technical field

Systems of electronic devices for the detection and localization of changes in predetermined spaces for the protection and safety of places, people and goods.

Background technique

Many place, people, and goods security and protection systems are implemented through the use of different types of sensors including, for example, thermal sensors, intrusion sensors, chemical sensors, environmental microphones, and cameras. In order to provide information necessary to protect and ensure the safety of places, people and goods, it is necessary to use information about any changes occurring in the space to be monitored. For example and for clarity, a change occurring in the monitored space could be the opening of a door or the presence in the room of a person who does not possess electronic identification.

Hitherto known security and protection systems activate an alarm whenever there is a change in the space monitored by the security and protection system, such as the opening of a door or the presence of a presence on a video display unit of a camera, which can be recorded by video The analysis algorithm interprets it as an intrusion.

Unfortunately, the system cannot choose when changes in a monitored space represent a threat to the safety and/or protection of that space without generating a large number of false alarms. In particular, the system is unable to correlate signals from various common sensors (which do not have specific characteristics and are currently available on the market) with each other in order to analyze all the possible identifications even by all common sensors of different technologies. Variation, the sensor monitors a given portion of the space to be monitored. Numerous tests have demonstrated that correlating sensors by differentiating events pre-defined by the user as relevant from those that are not leads to a substantial reduction in the number of false alarms while increasing the selectivity of the protection and safety system.

The exact position of each individual change in space represents an essential element for correctly relating the changes detected by the sensors to each other.

This lack of selective capability of hitherto known safety and protection systems is partially offset by the use of GPS eg for the geographic location of foreign bodies causing changes in the monitored space.

Unfortunately, the adoption of the GPS system has a number of disadvantages:

• Inherent inaccuracies in GPS technology.

The fact that the GPS system is rarely able to locate changes: As mentioned above as an example, foreign bodies that produce changes are not provided with and cannot be located with the help of GPS detectors that can at best locate detected changes The sensor, of course, is not the change itself. This deficiency is clearly the main disadvantage of the hitherto known safety and protection systems.

・The GPS system cannot be used in all locations. For example, it cannot be used indoors, especially in the case of protecting such a location as a bank's underground vault.

The GPS used in hitherto known safety and protection systems uses a two-dimensional coordinate system which does not allow positioning variations in three-dimensional space: for example considering the position of an operator performing his own activities in a suspended position (e.g. on a steel tower or scaffolding) protection requirements. Accidental displacement of the operator towards the danger zone cannot be detected by hitherto known safety and protection systems using GPS systems, leading to the risk of accidents.

• The use of sensors equipped with GPS is an additional cost to the system.

Contents of the invention

The hitherto known disadvantages are overcome by a system of electronic devices for the detection, location and correlation of changes in the space, for the protection and safety of places, people and goods in the space, which will be addressed below The system is described.

The system according to the invention also defines further improvements to the place, people and goods protection and security system also described below. The system according to the invention is able to correlate the changes of the signals from the sensors based on criteria related to their coherence in space in an innovative and advantageous manner, thus allowing an accurate assessment of events based on safety rules preset by the user and Classify it as a relevant event or a non-relevant event. This characteristic will be illustrated more extensively in the description of Fig. 2, which shows, by way of example and with specific reference to said relevant characteristic, the mode of operation of the system according to the invention.

The system according to the invention of electronic devices for the detection and localization of changes in predetermined spaces for the protection and safety of places, people and goods is based on a first data processing electronic device comprising at least two sensors, a user interface and at least one second 2. Architecture of data processing equipment.

It is pointed out here that by one or more sensors is meant one or several sensors as defined above generally available on the market, ie without any specific characteristics for use in the framework of the present invention.

The first data processing device is connected to a second data processing device. In a preferred embodiment, the first device is separate from the rest of the system and is preferably a personal computer, smartphone, tablet, or terminal equipped with a user interface.

The second device, which is more complex than the first device, is equipped with a first electronic module which, based on the mentioned location to be monitored, renders the location to be monitored into a three-dimensional virtual reality with an appropriate fidelity . It is pointed out that the degree of fidelity with which the location to be monitored is reproduced by the first electronic module into three-dimensional virtual reality depends on the monitoring requirements set by the user. For this reason, the words "appropriate fidelity" have been used to describe how the first electronic module reproduces the location to be monitored into three-dimensional virtual reality.

If the place to be monitored is a square, the level of fidelity required to reproduce the square in 3D virtual reality is lower than when the place to be monitored is a room. Objects and elements to be monitored are usually of larger size in squares than in rooms: in squares, for example, cars or people have to be monitored, while in rooms, for example, paintings have to be monitored. , Vase, Paper, People. In the example above, the level of fidelity required to render the plaza into 3D virtual reality is lower than that required for the room according to the example above, where objects and elements to be monitored typically have a larger Dimensions of objects and elements present in the room.

Said second data processing device is suitably preset to:

obtaining and storing from the first device a set of security rules set by a system user for the location to be monitored;

Receiving data and/or signals from sensors, both of which are referred to herein as "signals";

continuously and three-dimensionally map changes in values representing signals received from sensors into the mentioned three-dimensional virtual reality over time;

for each part of the three-dimensional virtual reality, processing all variations of the signals mapped thereon to extract data suitable for applying said set of security rules set by said user for said place to be monitored;

correlating changes in signals received from different sensors and referring to the same part of space with each other;

applying the set of security rules set by the user for the location to be monitored based on processing of changes to the mapped signal;

An alarm signal specified by said rules is activated on the first electronic device and/or other external devices.

As mentioned above, the second data processing device maps changes in the signals from the sensors over time into three-dimensional virtual reality. This mapping is performed on the basis of: the subdivision of the virtual reality according to a cell-based three-dimensional grid; the association of each sensor's three-dimensional grid and its respective signal with the cells.

In order to properly process the signals from the sensors, said second data processing device comprises one or several third data processing devices independent of each other and communicating with each other. Each of these devices is referred to below as a "proxy device".

Each proxy device is connected to at least one sensor and is capable of processing the signals of each sensor it is connected to.

In order to properly process the signals from the sensors, said second data processing device also includes a fourth data processing device (hereinafter referred to as a gateway) capable of: Those agent devices of signals associated with a collection of cells, hereinafter referred to as "associated agents";

The association between the proxy devices identified in this way is activated.

Each proxy device is able to independently analyze the signal from the sensor.

Based on an analysis of changes in said signal, each agent device:

infer the occurrence of an object or event;

classify said object or said event by type;

placing said object or said event in a cell of a grid of virtual reality;

The probability of being wrong or the reliability of being correct is calculated alternatively, hereinafter referred to as "reliability".

By means of said feature, each agent device is able to continuously communicate its own analysis results and its respective reliability to the remaining agent devices associated with said each agent device.

Thus, each agent device is able to process the analysis results and reliability received from each relevant agent as well as its own analysis results and reliability to arrive at an overall analysis result and overall reliability. In the system according to the present invention, overall analysis and overall reliability are performed by an agent device automatically identified based on predetermined criteria, and the agent device transmits the result of the overall analysis and the overall reliability to the gateway. The transmission is done continuously, and similarly, the proxy device that transmits the results of the overall analysis and the overall reliability to the gateway is continuously identified based on preset criteria.

Finally, the gateway applies the set of security rules set by the user for said place to be secured and protected by activating specified notifications and/or alarm communications based on the results of the overall analysis mentioned and the overall reliability, e.g. it activates a visual An alarm, such as a flashing light, or a signal is sent to the first data processing device, such as an audible signal or a message.

Detailed ways

Figure 1 shows a system (1) of electronic devices for the detection and localization of changes in predetermined spaces for the protection and safety of places, people and goods. Said figure 1 shows four sensors (2) and first data processing electronics (3). Said device (3) can be a personal computer, as shown in the figure, but it can also be a tablet, a smart phone, or any other terminal equipped with a user interface.

The second data processing device (4) is shown in dashed lines. Said second device (4) may be implemented on any hardware (eg server) suitable for processing data.

The device (4) is connected to a first data processing device (3) and comprises a first electronic module (5) (not shown in the figure) which is to be monitored with appropriate fidelity ( A) (not shown in the figure) rendering into three-dimensional virtual reality (not shown in the figure). In the second device (4), there is also a second electronic module (6) (not shown in the figure), which is capable of acquiring and storing the set of security rules set by the user for the place (A), receiving data and/or signals from sensors (2), mapping values and changes representing signals from the sensors into said three-dimensional virtual reality in a continuous manner over time, in three dimensions, and for each portion of the three-dimensional virtual reality , process all signals mapped onto it to extract data suitable for applying the set of security rules set by the user for the place (A), apply the set of security rules set by the user for the place (A) based on processing of the mapped signal ) set security rule set, and activate the alarm signal specified by it on the first data processing device (3) and/or other external devices.

Mapping over time the values representing the signals from the sensors (2) into a three-dimensional virtual reality is performed by the second data processing device (4) on the basis that the virtual reality is based on the detailed , the three-dimensional grid of each sensor (2) and the association of its respective signal with the cell. This mapping is not shown in the figure due to the apparent difficulty of representation.

Figure 1 also shows the presence of a third data processing device (7), called a proxy device, in the second data processing device (4). The agent devices (7) are represented graphically as four devices. They are suitable for processing signals from sensors. They are independent of each other and communicate with each other. Each of said agent devices (7) is connected to a sensor (2). According to the invention, the agent device can in any case be connected to one or several sensors (2).

Each of said proxy devices (7) is adapted to independently analyze signals successively from the sensors in order to:

- recognize the occurrence (change) of an object or event;

- categorizing (categorizing) said objects or said events by type;

- positioning said object or said event with reference to a cell of a grid of virtual reality (positioning);

- Alternatively calculate the probability of being wrong or the reliability (reliability) of being correct for the analysis done.

Each of the agent devices (7) is also able to process the results of the analysis done and the reliability received from each agent device (7) in relation to the results of its own analysis (collectively referred to as "overall analysis and overall reliability") to continuously communicate each change, classification, location (collectively referred to as "results of the analysis") and their respective reliability to the remaining agent devices (7) associated with said each agent device, And the overall analysis and overall reliability can be continuously communicated to the gateway device (8), as already mentioned in the summary of the invention. The transfer is performed by an agent that is automatically identified based on predetermined criteria.

Figure 1 also shows the presence of a fourth data processing device (8), called a gateway, in the second data processing device (4). Said fourth device is capable of identifying the proxy device (7) having the signal of the sensor to which each proxy device (7) is connected associated with the set of cells of the three-dimensional grid characterized by a non-empty intersection, called are "associated agents" and can activate associations between said thus identified agent devices (7).

The gateway (8) is also able to apply the set of security rules set by the user for said place (A) based on the above-mentioned overall analysis and overall reliability by activating notifications or alerts predetermined by the user.

Figure 2 shows an example of the operation of the system for classifying changes according to the invention. Two sensors ( 2 ¹ and 2 ² ), which in this example are two cameras, monitor the common area of the place (A) to be monitored. The agent devices (7 ¹ and 7 ² ) are related to each other, connected to the sensors (2 ¹ and 2 ² ) monitoring the common area as already mentioned.

In the example shown in Figure 2, each of the sensors (2 ¹ and 2 ² ) detects a change. Changes detected by each sensor (2 ¹ and 2 ² ) are localized by determining that both sensors ( 2 ¹ and 2 ² ) detect changes in the same location based on the mapping of the second electronic module ( 6 ).

In fact, each of said sensors detects a change and transmits its respective signal to the proxy device (7 ¹ or 7 ² ) to which it is connected.

Said agent devices (7 ¹ and 7 ² ) recognize that the occurrence of an object or event does occur, in other words there is a change, as defined above in the summary of the invention. Changes are located and categorized with reference to cells of virtual reality: in this example, would be the presence of a person as shown in the graphical representation of FIG. 2 . The system according to the invention determines that one person is involved, since each of the two agent devices (7 ¹ and 7 ² ) related to each other transmits to the other the detected change, its type and its location. In the example shown in Figure 2, each of the devices ( ⁷¹ and ⁷² ) communicates to the other that it has been identified as being attributable to a person who can be classified with a certain reliability as being in a precise location in virtual reality change of the object. In case the location is the same for both changes, each agent (7 ¹ ) and (7 ² ) recognizes that both changes correspond to the same change. Said changes are comprehensively classified by proxy devices (7 ¹ and 7 ² ) based on the classifications provided by both said proxy devices and their respective reliability.
