Description

The present application claims priority according to Chinese Patent Application No. 202010232145.X, filed with the National Intellectual Property Administration of China on March 27, 2020, entitled “Action Determination Method, System and Apparatus,” herein incorporated by reference in its entirety.

Technical field

This application relates to the field of computer technology and, in particular, to a method, system and device for determining an action.

State of the art

The device linking application allows the server to determine an action appropriate for an event detected by an event detection device according to the script associated with that event, and to trigger another device according to that script to perform the specified action. For example, in one security scenario, after an alarm device detects an alarm event, it reports the alarm event to the server. Upon receiving this alarm event, the server determines that video recording is an appropriate action and triggers the tracking device to record.

In practice, if the appropriate action is determined by the event, the adequacy of the determined action is low. Therefore, it is necessary to use multiple events to jointly determine the appropriate action, i.e. it is necessary to use a group of events to determine the appropriate action, which increases the adequacy of the action definition. For example, in the above case, the recording action is determined directly by the alarm event, but it may happen that the tracking device does not detect the target object. In this case, the recording action determined by the alarm event is not adequate, but triggering the tracking device to perform the recording action will still occur, resulting in the creation of unnecessary data records.

From the above, it is clear that there is a pressing need for an action determination method to efficiently determine an appropriate action jointly across multiple events.

Since the interval between the times of presence of any two events in the target event group does not exceed the predetermined permissible duration of non-synchronization, all events in the target event group can be considered to occur at the same time, and then the appropriate action for the target event group can be taken determined by the association rule.

Carrying out the invention

To create a clearer idea of the purposes, technical solutions and advantages of the invention according to this application, it will be disclosed in detail below using examples of the accompanying drawings and in the section “Implementation of the invention.” Of course, the disclosed embodiments represent only some, but not all, embodiments of the invention herein. All other embodiments obtained by those skilled in the art based on the embodiments contained in this application are included within the scope of protection of this application.

To achieve the goal of determining a suitable action jointly from multiple events, in one embodiment of the present application, a method for determining an action is provided. Moreover, the method for determining an action can be used in a server that is part of the action determination system. Moreover, the action determination system additionally contains at least one event detection device. An event detection device is, in particular, a device for detecting an event occurring. For example, the above event detection device may be an alarm device for detecting an alarm event.

Referring to FIG. 1. FIG. 1 is a flow diagram of a method for determining an action according to one embodiment of the invention according to the present application. The method for determining an action includes steps 101-102, in which:

Step 101: The current event detected by the event detection device is obtained.

Specifically, when an event detection device detects an event, it can send the detected event directly to the server or forward the detected event to the server through another device. Moreover, the event content of any event may include, in particular, an event detection device identifier and an event identifier. The server can obtain information, such as the event detection device that detected the event and the type of event that occurred, from the contents of the received event.

Since the content of an event can be considered to characterize the event, in one case, sending a detected event to a server may mean sending the content of the detected event to the server. Based on this, Step 101 of obtaining the current event detected by the event detection device may mean obtaining the content of the current event detected by the event detection device.

The event detection device identifier may be at least one of a sequence number, a serial number, and a communication address of the device, and the event detection device that detected the event can be identified by the above identifier.

The event identifier may be an event code obtained by assigning codes to each possible event in advance, and the event that has occurred can be determined by the event identifier.

In one embodiment of the present invention, in the case of using an event detection device to detect events on multiple channels, said event content may further comprise an event presence channel identifier. An event presence channel is a channel in which an event detected by an event detection device occurs, and the event presence channel identifier may be a channel number, a signal transmission path sequence number, etc. The channel in which the event occurred in the event detection device can be determined by the channel ID of the presence of the event. Moreover, the above channel may represent an area where events can occur at the observation location, for example, a vehicle door area, an entrance area to an administrative building, a road intersection area, etc. The above channel may also be a connection related to an image acquisition device, such as a camera, where one camera corresponds to one channel.

For example, an access control device on a vehicle has an identifier M1, wherein the access control device M1 serves to detect events occurring on the left front door, left rear door, right front door and right rear door of the vehicle, that is, the access control device M1 serves to detect events occurring on 4 channels. Moreover, the channel identifier where the left front door is located is L1, the channel identifier where the left rear door is located is L2, the channel identifier where the right front door is located is R1, and the channel identifier where the right rear door is located is R2. Possible vehicle door events include an opening event and a closing event, where the opening event identifier is OP and the closing event identifier is CL. If the access control device detects the opening of the front left door, then an event with the content "M1-L1-OP" can be sent to the server, and the server can determine from the received event content that the access control device with ID M1 has detected that the opening event with ID OP occurred on the front left door corresponding to the L1 channel of the presence of the event.

To subsequently determine an action, after Step 101 in which the current event detected by the event detection device is obtained, the server may determine the time of occurrence of the current event.

In one embodiment of the present application, the server may determine the time contained in the content of the current event as the time of the presence of the current event. In particular, the specified event content may also include the presence time of the event, wherein the contained time is the time at which the event detection device determines the presence of the current event, whereby the server can directly determine the presence time of the event from the event content without having to determine the presence time of the event by his own clock and other information, which increases the efficiency of determining the action. In addition, there may be errors in the server's time systems and the event detection device, and there may be a delay in sending due to network latency during the event sending process, resulting in discrepancies between the time the current event is received by the server and the actual time the current event is available. events. In this way, the time contained in the event content serves as the presence time of the event, which can improve the accuracy of the presence time and, as a result, improve the accuracy of the search for matches of a group of events when searching for matches in a group of events occurring simultaneously in the future, to improve the adequacy of the definition target response action for a group of events.

In one embodiment of the present application, the server may determine the time of receipt of the current event as the time of the presence of the current event. In particular, the server may perform time alignment on the event detection device so that the server's time system and the event detection device's time system can be consistently consistent with each other, and also to enable the sending delay to be ignored when the event detection device sends events when the network is in good condition. In the above case, the server may take the time of receipt of the received event as the time of the presence of the event.

Moreover, in one embodiment of the present application, the above action determination system further comprises a relay server, wherein, after the event detection device detects a current event, it can send the detected current event to the relay server, and the relay server in turn , receives the current event and sends the current event to the server.

Step 102: If there is a target event group that matches any event group according to the association rule and contains the current event among the received events, determine the target response action appropriate for the target event group according to the association rule.

Moreover, the interval between the times of presence of any two events in the target group of events does not exceed a predetermined permissible duration of non-synchronization. In particular, since time discrepancies between different devices are possible, as well as delays in the process of transmitting events, there are also discrepancies in the availability of received events. If we take the permissible duration of non-synchronization as the permissible maximum discrepancy range, then we can consider that two events whose presence time interval is less than the above maximum discrepancy range are synchronously occurring events. The allowed duration of non-sync can be 2 seconds, 3 seconds, 5 seconds, etc. The target group of events may include events that occurred earlier and/or later than the current event. In another case, if it is possible to keep multiple devices in sync over time, the value of the specified permissible duration of non-synchronization can also be equal to 0. That is, if the time of occurrence of two events coincides, then the two events are considered to occur at the same time.

In one embodiment of the present application, if it is determined that the interval between the presence times of any two events in the target event group does not exceed a predetermined permissible duration of non-synchronization, then it may be determined that the interval between the earliest presence time and the latest the presence time of the presence times of all events in the target event group does not exceed the permissible duration of non-synchronization.

In addition, since the current event is a currently received event, in order to ensure that the current event is used as an event on which the action is triggered, the target event group contains at least the current event. The current event is the event being processed at the current time and represents the latest event received. For an event group that does not contain the current event, the start action process was completed before the current event was processed, and there is no need to repeat the specified process. Thus, the target event group includes at least the current event, thereby avoiding repeated execution of the action trigger steps and thereby saving computing resources.

The specified association rule is a pre-configured rule containing a pre-defined mapping between a group of events and a response action. Moreover, each group of events can correspond to one or more response actions, that is, one group of events can determine one or more response actions. Moreover, the contents of the response action may include an action identifier. The action identifier may be an action code obtained by assigning codes to each of the possible actions in advance, where the action may be identified by the action identifier. Moreover, these actions may also differ depending on specific application scenarios. For example, these actions may be video data storage, audio data storage, object recognition, and the like.

In one embodiment of the present application, a match with a group of events according to the linking rule means that the target group of events and the given group of events according to the linking rule contain the same number of events and the same event content. For a target group of events that matches the group of events by the association rule, the appropriate response action can be determined by the association rule. For a group of events that does not match any group of events according to the association rule, it is difficult to find a suitable response action according to the association rule.

Moreover, the specified event content can be characterized based on the event type and the resource number of the corresponding event detection device.

In another embodiment of the present application, when matching the target event group with the event groups according to the linking rule, in addition to the number of events contained and the content of the event, the time of occurrence of the event can also be taken into account. In this case, based on the above, it is determined that the target group of events coincides with the group of events according to the linking rule only when the times of occurrence of the events contained in the target group of events and contained in the group of events according to the linking rule also coincide.

In one embodiment of the present application, based on the received events, a search can be made for the presence of a target group of events that matches the group of events according to the association rule and contains the current event, and if such a target group of events is found, determine the target response action appropriate for the target group of events, according to the association rule.

Since the association rule contains a correspondence between an event group and a response action, and the target event group matches the event group under the association rule, a response action suitable for the target event group can be determined by the association rule, and a specific response action can be performed as target response.

In one embodiment of the present application, if multiple target event groups are received for a current event, then target responses corresponding to the corresponding target event groups can be found according to the corresponding association rule.

In one of the embodiments of the invention according to the present application, after receiving the current event at the specified Step 101, the value of the difference between the time of presence and the time of receipt of the current event can also be determined. If the difference value meets a predetermined delay tolerance condition, and there is a target event group matching the event group by the association rule and containing the current event among the received events, a target response action suitable for the target event group by the association rule can be determined. Moreover, if the presence time of the current event is the receiving time when the server receives the current event, the specified difference value is 0, and in this case there is no need to determine the difference value between the presence time and the receiving time.

Said delay tolerance condition may include that said difference value is not greater than a predetermined delay tolerance duration, or that said difference value is less than a predetermined duration threshold. Moreover, the specified duration of the permissible delay can be 7 seconds, 8 seconds, 10 seconds, etc. without limitation in this embodiment of the invention according to the present application. The specified duration of acceptable delay may be different from the duration threshold.

If the specified difference value is greater than the duration of the acceptable delay, or the difference value is not less than the predetermined threshold duration value, it indicates that the received event is abnormal, and therefore the target event group determination for the current event is not performed; Moreover, if the specified difference value is not more than a predetermined duration of the permissible delay or the difference value is less than a predetermined threshold duration value, the target group of events can be determined from the current event.

In one embodiment of the present application, the received event may be an event whose difference value between the presence time and the receipt time meets a predetermined delay tolerance condition from among the cached events detected by the event detection device. That is, in this embodiment, an event corresponding to the delay tolerance condition from among the cached events detected by the event detection device is referred to as a “received event.” In this way, events can be sorted to filter out unsuitable events, thereby increasing the adequacy and efficiency of identifying the target group of events. Moreover, if the presence time of the current event is the receiving time when the server receives the current event, the specified difference value is 0, and in this case there is no need to determine the difference value between the presence time and the receiving time.

In one embodiment of the present application, upon receiving an event detected by an event detection device, the received event may be cached.

In another embodiment of the present application, for each received event, after the event is received, a difference value between the presence time and the event receipt time can be determined, and the event is cached only if the difference value meets a predetermined delay tolerance condition, in As a result, for each of the cached events, the difference between the presence time and the reception time corresponds to a predetermined condition for the acceptable delay. Thus, all cached events meet the specified latency tolerance condition, and whenever a decision is made about whether to find a target response action after receiving the current event, the decision can only be made for cached events.

In another embodiment of the present application, the received event may be an event from among the cached events detected by the event detection device whose presence time is within the second time range. Moreover, the second time range is a time range specified with the current time as the reference point and a predetermined duration of the allowable delay as the extension duration. In particular, the received event may be cached, and when determining the target group of events, the target group of events is determined only from among the cached events whose presence time is within the second time range. Alternatively, it is also possible to cache only those events whose occurrence time is within the second time range, and filter events outside the second time range over time to discard events that occur too early and are unusable, thereby saving caching resources . Thus, the received events are events from among the cached events whose presence time is within the second time range.

In one embodiment based on the above-disclosed embodiment, it is possible to continuously search for events from among the cached events whose difference value between the presence time and the current time is greater than a predetermined duration of the acceptable delay; and filter out the found event from cached events.

In one embodiment of the present application, the received event may be not only an event that meets a predetermined delay tolerance condition, but also an event whose occurrence time is within the second time range. For example, if the delay tolerance condition is that the specified difference value is less than a predetermined duration threshold, and the specified duration threshold value and the delay tolerance duration are different from each other, then the specified received event is the intersection of an event of the second type with an event of the third type . Moreover, an event of the second type is an event whose difference value is less than the threshold duration value, and an event of the third type is an event whose presence time is within the second time range.

Determining an action using the solutions proposed in the embodiments includes the steps of: obtaining a current event detected by an event detection device; if there is a target group of events that matches any group of events according to the association rule and contains the current event among the received events, a target response action suitable for the target group of events is determined according to the association rule. Since the interval between the times of presence of any two events in the target event group does not exceed the predetermined permissible duration of non-synchronization, it can be assumed that all events in the target event group occur at the same time, and also that the response action is suitable for target group of events can be determined by the association rule. From the above, it follows that a suitable action can be determined jointly from a plurality of events by applying the action determination solution proposed in the above-disclosed embodiments.

The action determination solution proposed in the above-disclosed embodiments will be disclosed below with a specific example.

It is assumed that an infrared device for detecting whether emitted infrared rays are reflected, a camera 1 for acquiring images and detecting the presence of an object in the collected images, and a camera 2 for acquiring images and detecting a red light from the acquired images are located at the observation location. . The allowed duration of non-sync is 20 seconds. The association rule contains event group 1 and event group 2, wherein event group 1 includes a first event and a second event, event group 2 includes a second event and a third event, wherein the first event indicates that an object is detected, the second event indicates that infrared rays have been reflected, and the third event indicates that a red light has been run. The response action corresponding to event group 1 is recording by camera 1, and the response action corresponding to event group 2 is recording by camera 2.

If the infrared device detects that infrared rays have been reflected at the 10th second, a second event will be generated. The server receives the second event as the current event. Events received by the server up to this time include the second event received at 1 second, the third event received at 3 seconds, and the first event received at 8 seconds.

From the above, it follows that the target event group containing the first event received at the 8th second and the second event received at the 10th second is the same as the specified event group 1, with a time interval of 2 seconds between the 8th second and the 10th second does not exceed the permissible non-synchronization duration of 20 seconds, and the response action corresponding to event group 1 is a recording by camera 1. Thus, the target response is determined to be a recording by camera 1, and the camera Camera 1 starts recording.

In one embodiment of the present application, the response action content may further include a response device identifier.

Moreover, the response device is a device for performing a certain action. For example, the response device may be a hard disk device that performs the action of storing video data, or the like.

A response device identifier is an identifier of the response device, which may be at least one of a sequence number, a serial number, and a communication address of the device, wherein the response device may be identified by the specified identifier. Thus, not only the action taking place, but also the response device for performing that action can be determined by the content of the response action.

In one embodiment of the present application, if the response device is capable of performing a response action for multiple response channels, said action content may further include an action response channel identifier. An action response channel is a channel that is triggered as a reaction to a response action from among all the response channels of the response device. The action response channel identifier may be a response channel number or the like. An object that is triggered as a reaction to an action in a response device can be identified by the ID of the action response channel.

For example, the identifier of a video storage device in a surveillance system is H1, wherein the video storage device H1 is used to store video data transmitted by the first signal source, the second signal source, and the third signal source, i.e. Video storage device H1 can perform response actions for 3 response channels. Moreover, the identifier of the response channel where the first signal source is located is Y1, the identifier of the response channel where the second signal source is located is Y2, and the identifier of the response channel where the third signal source is located is Y3, and the response action performed by the video data storage device , includes a storage action whose identifier is S1. If the response action includes, but is not limited to: triggering a video storage device with response device ID H1 to perform a storage action with ID S1 in response to an input video signal from a second signal source with action response channel ID Y2, then the contents of the response action actions may represent "H1-Y2-S1".

Referring to FIG. 2. FIG. 2 is a schematic diagram of a binding rule according to one of the embodiments of the invention according to this application. The binding rule contains each event group and the response actions appropriate for the corresponding event groups. The event content of each event in the event group includes an event detection device ID, an event presence channel ID, an event ID. The content of each action in a response action includes a response device ID, an action response channel ID, an action ID. If the target event group is "C-2-2, H-6-1", the triggered associated action can be defined as the action "P-5-5" according to the presented association rule. Moreover, the first letters in “S-2-2” and “N-6-1”, namely C and N, are identifiers of event detection devices, and the first numbers, namely 2 and 6, are identifiers of availability channels events, with the second numbers representing event identifiers; wherein the letter P in "P-5-5" represents the response device identifier, the first number 5 represents the corresponding action channel identifier, and the second number 5 represents the action identifier.

If the target event group is "C-2-2, H-6-1", the linking rule can determine that the response action appropriate for the specified target event group is "P-5-5".

In one embodiment of the present application, after a target response action suitable for a target group of events has been determined by the association rule, said action determination method further includes the step of: triggering, depending on the determined target response action, a response device for performing a target response action.

Specifically, after a target response action has been determined, the server may determine a response device to perform the specified target response action based on the action content of the target response action and send an instruction to run the target response action to the specified response device. Upon receiving the trigger instruction, the reactor identifies the object to perform the action by the channel ID in the action content of the target response action and implements the target response action for the specific object.

In one embodiment of the present application, if multiple target responses are identified, instructions to trigger suitable target responses may be sent to the respective response devices to trigger each response device to execute the suitable target response.

In one embodiment of the present application, if the server includes a server and a relay server, then after a target response action is determined, the server may send an instruction to initiate the target response action to the relay server, and the relay server in turn , triggers the appropriate response device to perform the target response action.

In one embodiment of the present application, FIG. 3, upon receiving the current event at said Step 101, the method may further include the following steps 103-104, in which:

Step 103: Determine one or more groups of events to match containing the current event from among the received events.

Moreover, the interval between the times of presence of any two events in each of the defined one or several groups of events for comparison does not exceed the permissible duration of lack of synchronization.

In particular, if the number of received events does not include any other event that meets the requirement that the interval between the time of the presence of this event and the time of the presence of the current event should not exceed the permissible duration of lack of synchronization, i.e. If the interval between the presence time of any of the received events and the presence time of the current event exceeds the permissible duration of non-synchronization, the current event can be directly accepted as one or more event groups for comparison. Thus, one or more event groups for matching includes only the current event and does not include other events from among the received events.

If the received events include at least one other event that meets the requirement that the interval between the time of the occurrence of this event and the time of the presence of the current event should not exceed the permissible duration of non-synchronization, the current event may be combined with events of this type to form one or several groups of events to compare with the time interval of the presence of any two events not exceeding the permissible duration of non-synchronization. Since there are many combinations of multiple events, many groups of events can be obtained for matching. The matching event group may also contain only the current event, which is not limited in the embodiment of the present application.

For example, suppose that the received events include E1, E2, E3, and E4, where E3 is the current event, and the interval between the times of occurrence of any two specified events does not exceed the permissible duration of non-synchronization. In this case, the defined groups of events for comparison include: (E3), (E1, E3), (E2, E3), (E4, E3), (E1, E2, E3), (E2, E3, E4), (E1, E3, E4), (E1, E2, E3, E4).

In one embodiment of the present application, the number of events included in the group of events to be matched may be within a predetermined number range, wherein the predetermined number range may be [1, 4], [2, 4], [3 , 5], etc. If the number of events in an event group to match is too large, the combinations of the current event with other events will be too complex, which will consume significant computational resources and may not subsequently result in the event group to be matched with event groups by the association rule. If the number of events in the group of current events to match is too small, a response action may be determined with a small number of events present, which may reduce the adequacy of the determined response action. Limiting the number of events in an event group for matching to a predetermined number range not only improves matching efficiency, but also ensures that an appropriate response action is determined.

In one embodiment of the present application, the number of events in an event group for matching may not exceed the maximum number of events in each event group according to the association rule. For example, if a linking rule has 5 event groups, then the number of events in each event group is 3, 4, 2, 2, and 3, with a maximum of 4 events per group.

If the number of events in a matching event group is greater than the specified maximum number, an appropriate association rule response cannot be determined for that matching event group. Therefore, the number of events in a matching event group can be limited to no more than the above-mentioned maximum number, thereby reducing the likelihood of obtaining an unusable matching event group and thereby saving computational resources.

Step 104: Search the identified one or more matching event groups for a target event group that matches the association rule event group.

That is, the target group of events that matches the group of events according to the association rule is determined from among the identified one or more groups of events for matching.

In particular, a group of events to be matched can be matched sequentially with groups of events using a linking rule. If a group of events for matching and any group of events according to the linking rule contain the same number of events and the same events, we can assume that the group of events for matching coincides with this group of events according to the linking rule, i.e. the presence of a target group of events that matches the group of events according to the association rule can be established.

In one implementation, it is possible to determine whether the events are the same by the contents of the events.

Additionally, in one embodiment of the present application, when searching for a target event group, it is also possible to first search for a binding rule to determine if there is a comparable event group containing the current event. If there is no comparable event group, it means that the current event cannot trigger a suitable action. If there is a comparable group of events, it is decided whether each event in the comparable group of events occurred within the acceptable duration of non-synchronization before or after the time the current event was present. If each event occurred in this way, then the comparable group of events can be defined as the target group of events. The decision is made for each comparable group of events in turn until all comparable groups of events have been reviewed.

Referring to FIG. 4. FIG. 4 is a flow diagram of another method for determining the action of one of the embodiments of the invention according to the present application. The above-disclosed Step 103, which determines one or more groups of events to match, may, in particular, include the following steps 1031-1032, in which:

Step 1031: Add the current event to the event queue depending on the time of the current event.

Moreover, an event queue is a queue in which received events are arranged in order by time of availability. The specified order by availability time includes the order of availability from early to late and the order of availability from late to early.

In one of the embodiments of the present application, the difference between the time of presence of the current event and the time of receipt of the current event can be determined. If the difference value is greater than the predetermined tolerable delay duration, it means that the received event is an anomalous event, and therefore the current event is not added to the event queue. If the specified difference value is not greater than the predetermined duration of the acceptable delay, the specified current event can be put in the event queue at a position corresponding to the time it occurred.

For example, suppose the current event's receive time is the 15th second and the preset delay time is 6 seconds: if the current event occurs at the 10th second, then the difference between the receive time and the presence time is less than the preset delay time , in connection with which the current event is added to the event queue; if the current event occurs at the 5th second, then the difference between the specified receiving time and the presence time is greater than the specified predetermined duration of the permissible delay, and therefore the current event is not added to the event queue.

In one embodiment of the present application, the events placed in the event queue may be events occurring within the second time range.

Moreover, the second time range is a time range specified with the current time as the reference point and a predetermined duration of the allowable delay as the extension duration. For example, if the current time is the time at the 8th second, and the predetermined duration of the allowable delay is 5 seconds, then the second time range is the time range from the time at the 3rd second to the time at the 13th second.

In this case, the events cached in the event queue are events for which the difference between the available time and the current time is no more than a predetermined duration of the acceptable delay.

In particular, with respect to a received event, as time passes, an event whose difference value between the availability time and the current time is greater than the predetermined duration of the acceptable delay is discarded from the event queue. Thus, events cached in the event queue represent events whose availability time is close to the current time, and events that occur too early and are unusable are discarded, thereby reducing the length of the event queue and saving caching resources.

Step 1032: Determine one or more groups of events to match containing the current event from the event queue based on the tolerable duration of non-synchronization.

For example, each of the events can be matched one at a time in an event queue based on the tolerable out-of-sync duration to obtain events whose presence time interval does not exceed the allowed out-of-sync duration to determine a group of events to match based on the events received.

In one embodiment of the present application, the event queue may include a plurality of positions, wherein each position corresponds to one point in time, wherein the times associated with corresponding positions in the event queue are subject to a predetermined change rule, wherein the position of each events in the event queue is the position corresponding to the time of occurrence of this event. In particular, said predetermined change rule may be a forward chronology rule, but is of course not limited to a progressive rule and may also be a backward chronology rule, for example.

Thus, for an event occurring at any point in time, a position corresponding to that point in time in the event queue can be determined, after which the event is added to a certain position.

Referring to FIG. 5. FIG. 5 is a schematic diagram of an event queue according to one of the embodiments of the invention according to this application. In FIG. 5, the numbers 0, 1, 2... indicate the corresponding moments in time, while each position in the event queue is indicated by a grid, i.e. each time moment corresponds to one position, and the chronology of time points corresponding to the corresponding positions is direct. Each event is placed in the event queue depending on the moment in time corresponding to the time of availability. Let us assume that the current event is event 4, and the time of occurrence of event 4 is the time at the 4th second, and therefore the specified event 4 is placed at the position corresponding to the 4th second, as shown in the figure.

In one embodiment of the present invention, the times associated with the corresponding positions in the event queue may be times within the second time range. In this way, all events cached in the event queue are events that have a presence time close to the current time, and events that occur too early and are unusable are discarded, reducing the length of the event queue and saving caching resources.

In one embodiment of the present application, if each position in the specified event queue corresponds to one point in time, then in the above Step 1032, in which one or more groups of events are determined for matching, one or more groups of events for matching are determined containing the current event, from the event queue by sequential matching in the event queue in the matching period. The specified comparison period is not a real, but a virtual period for determining events from the event queue over a certain length. When defining an event, the identified event is the event located within the matching period.

Moreover, the length of the comparison period is the length corresponding to the permissible duration of non-synchronization in the event queue. That is, if we characterize the length of the comparison period in terms of duration, the length of the comparison period does not exceed the permissible duration of non-synchronization, and therefore the interval between the times of the presence of any two events in the comparison period does not exceed the permissible duration of non-synchronization, and, therefore, the events in the comparison period can be considered synchronous events. Thus, events obtained by comparison, for which the interval between the times of the presence of any two events does not exceed the permissible duration of non-synchronization, can be ignored and, thereby, the efficiency of the comparison can be increased.

The length of the matching period is preferably equal to the permissible duration of non-synchronization. In this case, a maximum number of events can be determined at one time with an interval between the times of presence of any two events not exceeding the permissible duration of non-synchronization, based on the comparison period.

In addition, if the length of the comparison period is less than the permissible non-synchronization duration, then the difference between the length of the comparison period and the length of the permissible non-synchronization duration can be set to be less than the predetermined difference in length. The specified predetermined length difference can be found depending on the accuracy of the event duration.

In another embodiment of the present application, the length of the comparison period may also be no less than the length between adjacent positions corresponding to adjacent times in the event queue. For convenience of description, this length is hereinafter referred to as “extent between adjacent positions.” If the length of the comparison period is less than the specified length between adjacent positions, the comparison period can only contain events that occurred simultaneously at the same time, and only the current event could have occurred simultaneously, resulting in the resulting group of events for comparison containing only the current event, then it is difficult to find a response to many events. If the length of the matching period is not less than the specified length between adjacent positions, the matching period may contain events that occurred at two or more times at the same time, so the probability of having multiple events in the group of events to match is high, and it is easier to find a response action from the set events. It should be noted that in this case, when obtaining a group of events for comparison, it is necessary to take into account the interval between the times of the presence of any two events, while events with an interval exceeding the permissible duration of non-synchronization are excluded, so that the interval between the times of the presence of any two events in the group of events for comparison did not exceed the permissible duration of non-synchronization.

The maximum number of events in an event group for matching is related to the length of the matching period. The longer the comparison period, the more time points the comparison period contains. Since each point in time corresponds to one position in the event queue, and one or more events can occur at each position, the longer the matching period, the greater the maximum number of events in the event group for matching.

In particular, in the process of sliding the comparison period, there may be multiple events in the comparison period, including the current event. By combining multiple events in a matching period, you can obtain multiple matching event groups containing the current event.

Referring to FIG. 6. FIG. 6 is a schematic diagram of a comparison period according to one of the embodiments of the invention according to this application. If, as shown in FIG. 6, the permissible duration of non-synchronization is 4 seconds, and the length of the matching period is the length between corresponding places in the event queue at times with an interval of 4 seconds. Assuming that the current event is event 4, the matching period slides to the current position, and that the matching period contains event 2, event 3, and event 4. The matching event groups derived from the matching period include: ( event 4), (event 2, event 4), (event 3, event 4), (event 2, event 3, event 4).

In one embodiment of the present application, since the group of events to be matched must contain the current event, when the matching period slides, the current event must also remain within the matching period. The matching period sliding range is a queue area corresponding to a first time range in the event queue, wherein the queue area corresponding to the first time range is an area between a start position corresponding to the start time of the first time range and a final position corresponding to the end time of the first time range.

Moreover, the first time range is a range with the time of presence of the current event as the center and the permissible duration of the lack of synchronization as the duration of the extension. Specifically, it represents the first time range obtained by extending forward and backward, respectively, with the tolerable duration of non-synchronization as the extension duration and the presence time of the current event as the center. For example, if the reference time is the time at the 5th second, and the acceptable duration of non-synchronization is 3 seconds, then the first time range is the range from the 2nd second to the 8th second.

The queue area corresponding to the first time range is an area formed by positions in the queue corresponding to corresponding times in the first time range. Take FIG as an example. 5: If the first time range lasts from 0th second to 4th second, then the queue area corresponding to the first time range is the area formed by 4 positions from the left; if the first time range lasts from 0 to 8 seconds, then the queue zone corresponding to the first time range is the zone formed by 8 positions from the left.

Take FIG as an example. 6: The queue zone corresponding to the first time range is the zone from the 0 second place to the 8 second place in the event queue, and the sliding of the matching period must occur within the specified queue zone.

In one embodiment of the present application, matching can be performed sequentially from a position corresponding to the start time of the first time range as a starting position in the queue area corresponding to the first time range in the event queue by sliding the matching period within a predetermined the length of the sliding step. During the matching process, a group of events to match in the matching period containing the current event is searched for in a given queue area until the matching is completed.

The predetermined length of the sliding step may be the extent between adjacent positions corresponding to adjacent times in the event queue, or the extent between positions corresponding to time ranges separated from each other by a plurality of times, or a predetermined fixed duration.

In one embodiment of the invention of the present application, a predetermined length of the sliding step can be set depending on the accuracy of the timing of the occurrence of the event. For example, if the event presence time precision is 1 second, then the predetermined length of the sliding step can be set to the length corresponding to the time interval of 1 second in the event queue; If the event presence time accuracy is 0.1 seconds, then the predetermined length of the sliding step can be set to the length corresponding to the time interval of 0.1 seconds in the event queue.

Events within the matching period can be combined with the current event to form one or more matching event groups containing the current event until the matching ends.

In one case, if along the sliding direction of the matching period, the number of events corresponding to positions from the first position to the second position in the event queue is less than a predetermined number of events, it may indicate the end of the matching, the first position being the position corresponding to the starting side of the matching period in the first time range, and the second position is the ending position in the first time range.

The above one example of "end matching" in this embodiment is not limiting.

Additionally, in one embodiment of the present application, the binding rule comprises a mapping between a group of events, a response action, and a trigger time range. That is, for each group of events, the appropriate response action and the trigger time range corresponding to this group of events are written according to the association rule.

The specified trigger time range can be considered as the time range for applying the association rule. If the occurrence time of events in the target event group is within the specified trigger time range, the appropriate response action is determined by the association rule on the target event group as the target response action. If the occurrence time of events in the target event group is outside the specified trigger time range, the linking rule is considered not to apply and a suitable response action is not determined by the linking rule as the target response action.

The specified start time range can be preset depending on the application scenario. Let's take as an example an access control device in a certain company. During the time period 8:00-17:00 from Monday to Friday, the frequency of entry and exit of personnel into and out of the company is high, and in the rest of the time period it is low. Therefore, the trigger time range of the access control device to start access control can be set as the period 8:00-17:00 from Monday to Friday.

In one embodiment of the present invention, when determining a target response action, a target trigger time range corresponding to a target group of events can be determined by an association rule. If there is an intersection of the target trigger time range with the third time range, a response action suitable for the target event group is determined as the target response action. The specified trigger target time range is the trigger time range captured as part of the association rule match for the target event group.

Moreover, the third time range is the range from the earliest availability time to the latest availability time from the availability times of events in the target event group. For example, if the earliest availability time in the target event group is 15:00:05 and the latest availability time is 15:00:12, the third time range is the range from 15:00:05 to 15:00:12.

In particular, if there is an intersection of the target trigger time range with the third time range, the occurrence time of events in the target event group can be considered to be within the target trigger time range, and the trigger rule takes effect. Therefore, a response action suitable for the target group of events is determined as the target response action. If the target trigger time range does not intersect with the third time range, the timing of events in the target event group can be considered to be outside the target trigger time range and the trigger rule does not take effect, causing the target response action to be determined.

Referring to FIG. 7. FIG. 7 is a schematic diagram of another linking rule according to one embodiment of the invention according to the present application. Suppose the target event group is "A-1-1, B-2-1, D-3-2", the third time range related to the target event group is the range 0:00:56-1:00:02 Monday, and the target launch time range is 1:00:00-5:00:00 Monday. It is obvious that the third time range intersects with the target trigger time range, and therefore the said rule is considered to be in effect. Therefore, “R-1-3” is defined as the target response action.
