Description

Access control system

This creation is about an access control system, especially an access control system that can be automatically set and secured.

The traditional security system is to activate the security function when there is no one in a specific area (such as a building or a house), and an alarm can be triggered when there is a small intrusion into the area or the entrance and exit are damaged. However, the user must remember to enable the security function when leaving to obtain the corresponding protection. Before entering the range, the security function must be released and the access control verification must be performed before entry.

The aforementioned security system cannot be applied to the entrances and exits (such as community gates, side entrances) where people often enter and exit, and there is a lack of security guarantees. Even if the security system is used, it is quite inconvenient for the user. The user must first release the security function, and then perform the access control verification to unlock the door, and close the door after unlocking and passing, and remember to re-enable the security function.

In view of this, this creation proposes an access control system that can automatically release and set security in response to passers-by passing through the entrance and exit.

In one embodiment, the access control system includes an access control host, a lock detection device, and a security host. The access control host is used to obtain and verify an identity information and control a door lock according to the verification result. The lock detection device detects whether the door lock is locked or unlocked. The security host has security mode and release mode, and communicates with the lock detection device to obtain the detection result of the lock detection device, and enters the security mode in response to the door lock changing from the unlocked state to the locked state, and responds to the door lock from The locked state changes to the unlocked state and enters the release mode.

In summary, the access control system proposed in this creation can automatically set and release security according to the locked state of the entrance and exit, so that the person who wants to pass only needs to perform identity verification once to pass, and automatically release and set security before and after passing.

Regarding the terms "first" and "second" used in this article, they are used to distinguish the referred elements, not to sort or limit the differences of the referred elements, and are not used to limit the creation The scope. Moreover, the term "coupling" as used means that two or more elements make physical or electrical contact with each other directly, or make physical or electrical contact with each other indirectly; for example, if the first device is described in the text as being coupled In the second device, it means that the first device can be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connecting means. The "communication connection" used in this article refers to wired communication or wireless communication between two or more components.

Referring to FIG. 1, it is a schematic diagram of the architecture of the access control system of the first embodiment of the present creation. The access control system is applied to an entrance and exit, and the entrance and exit includes a door lock 1 for opening or closing the entrance and exit. The access control system includes an access control host 2, a lock detection device 3, and a security host 4.

Here, the door lock 1 is an electronic lock, which operates through power supply and receives a control signal to unlock it. In some embodiments, the door lock 1 is an anode lock or a magnetic lock. When the power supply is lost, the door lock 1 will be in the unlocked state; otherwise, the door lock 1 will be in the locked state. In some embodiments, the door lock 1 is a cathode lock. When the power supply is lost, the door lock 1 will be in the locked state; otherwise, the door lock 1 will be in the unlocked state.

The access control host 2 is used to obtain and verify the identity information of the person to pass, and to control the door lock 1 according to the verification result. The access control host 2 can confirm the identity of the person who wants to pass according to the access control card induction, password input, fingerprint recognition, face recognition and other methods. When the verification is passed, the access control host 2 outputs a control signal to the door lock 1 to unlock the door lock 1.

The lock detection device 3 can detect whether the door lock 1 is in a locked state or an unlocked state. In one embodiment, the lock detection device 3 is coupled to the lock status output terminal of the door lock 1 to detect the output signal of the lock status output terminal to identify the door lock 1 in the locked state or the unlocked state. In one embodiment, the lock detection device 3 is coupled to the control terminal of the door lock 1 to detect the control signal input to the door lock 1 to identify the door lock 1 in the locked state or the unlocked state. In one embodiment, the lock detection device 3 detects whether the bolt of the door lock 1 is in the unlocked position, so as to identify whether the door lock 1 is in the locked state or the unlocked state. Here, the lock detection device 3 may be, for example, a light detector, which recognizes whether the lock tongue is in the locked position by identifying whether the light received by the light detector is blocked.

The security host 4 has a security mode and a release mode, and is connected to the security control center. In the security mode, the security host 4 will send an alarm to the security control center based on the trigger of the security sensor (such as a glass vibration sensor) connected to the communication. The security sensors are arranged at the corresponding entrances and exits to detect abnormal intrusion events at the entrances and exits. In the release mode, the security host 4 will ignore the triggering of the security sensor and will not send an alarm to the security control center. The security host 4 communicates with the lock detection device 3 to obtain the detection result of the lock detection device 3, and enters the security mode in response to the door lock 1 changing from the unlocked state to the locked state, and responds to the door lock 1 from the locked state Change to the unlocked state and enter the unlocked mode. Thereby, when the door lock 1 is unlocked, the security host 4 will automatically enter the release mode; when a person who wants to pass through the entrance and exit, the door lock 1 will be locked so that the security host 4 will automatically enter the security mode. Therefore, people who want to pass do not need to perform complicated steps such as security release, identity identification, security setting, etc., entrances and exits can still be maintained under security monitoring, and at the same time, legitimate personnel can pass freely.

In some embodiments, in order to avoid misoperation caused by the time difference between unlocking the door lock 1 and releasing the security mode (that is, the door lock 1 is unlocked before entering the release mode, causing an alarm to be issued), the security host 4 sets an allowable time. If the allowable time elapses after the door lock 1 is unlocked, the security host 4 is still in security mode, and the security host 4 will issue an alarm; otherwise, if the security host 4 has entered within the allowable time after the door lock 1 is unlocked If the mode is released, no alarm will be issued.

In some embodiments, the access control system includes two access control hosts 2, which are respectively arranged at both ends of the entrance and exit, so as to perform identity verification for the persons who want to pass from both ends. When any access control host 2 unlocks the door lock 1 due to the verification, the security host 4 will automatically enter the release mode. When the door lock 1 is locked, the lock detecting device 3 will detect that the door lock 1 is changed from the unlocked state to the locked state, so that the security host 4 enters the security mode.

Refer to Fig. 2, which is a schematic diagram of the architecture of the access control system according to the second embodiment of the present creation. Compared with the first embodiment, the access control system of the second embodiment may further include a door opening button 5, a door detecting device 6, a setting device 7 and a warning device 8. However, it is understandable that in some embodiments, in addition to the constituent elements of the access control system of the first embodiment, it may only include part of the door opening button 5, the door detecting device 6, the setting device 7, and the warning device 8. element.

As shown in FIG. 2, the door opening button 5 is coupled to the control terminal of the door lock 1 and outputs a control signal to unlock the door lock 1 in response to a pressing action. The access control host 2 and the door opening button 5 are respectively arranged at both ends of the entrance and exit. In this way, a person who wants to pass at one end close to the door opening button 5 only needs to press the door opening button 5 to unlock the door lock 1 without verification of identity.

As shown in FIG. 2, the door detection device 6 is connected to the security host 4 in communication. The door detecting device 6 is used for detecting whether the door corresponding to the door lock 1 is in an open state or a closed state. The door detection device 6 sends a warning signal to the security host 4 when the duration of the door open state exceeds a threshold (for example, more than three minutes). In this way, the security host 4 can send a notification message to the manager's device (for example, the manager's mobile phone) in response to the warning signal, so that the manager can know that the door has been opened for too long. The sending method of the notification message may be, for example, push broadcast, short message, email, etc.

Referring to FIG. 3, it is a schematic diagram of the structure of the lock detection device 3 and the door detection device 6 according to an embodiment of the present invention. The lock detection device 3 is implemented by the first I/O device 31. The first I/O device 31 includes an input terminal I1 and an output terminal O1. The door detection device 6 includes a magnetic reed sensor 61 and a second I/O device 62. The second I/O device 62 includes an input terminal I2 and an output terminal O2. The input terminals I1 and I2 respectively include one or more digital input pins; the output terminals O1 and O2 respectively include one or more digital output pins.

The input terminal I1 of the first I/O device 31 is coupled to the lock state output terminal of the door lock 1 to detect that the door lock 1 is in the unlocked state or the locked state. The input terminal I2 of the second I/O device 62 is coupled to the magnetic reed sensor 61 to detect whether the door is in the door open state or the door closed state. The input terminal I2 of the second I/O device 62 is also coupled to the output terminal O1 of the first I/O device 31. In response to the first I/O device 31 detecting that the door lock 1 has changed from the locked state to the door locked state, the output terminal O1 of the first I/O device 31 continues to output the first maintenance signal for a period of time (for example, three minutes), to The input terminal I2 of the second I/O device 62 remains at the result of detecting that the door is closed, and the first sustain signal is not output after this period of time, so that the input terminal I2 of the second I/O device 62 It is detected that the door is open, so that the second I/O device 62 sends the aforementioned warning signal to the security host 4. It can be understood that the first I/O device 31 has a timer to count the duration of the first sustain signal; the first I/O device 31 and the second I/O device 62 respectively have communication modules for communicating with the security host 4.

Refer to Figure 2 and Figure 3 together. The setting device 7 is connected to the security host 4 in communication. Specifically, the setting device 7 has an operating interface (such as a button) and a communication module connected to the security host 4 for communication. The setting device 7 can send a setting signal to the security host 4 to activate an extended door opening function. The security host 4 responds to the setting of the extended door opening function so that the door detecting device 6 does not issue a warning signal. For example, when the user needs to open the door for a long time, the setting device 7 can be operated to send a setting signal. After receiving the setting signal, the security host 4 can send an exemption instruction to the second I/O device 62. The output terminal O2 of the second I/O device 62 is coupled to the input terminal I2 of the second I/O device 62. According to the non-sending command, the output terminal O2 of the second I/O device 62 continues to output the second sustain signal for a period of time, so that the input terminal I2 of the second I/O device 62 remains at the result of detecting the door closed state. Therefore, during this period of time, although the door is actually in an open state, the second I/O device 62 will not send the aforementioned warning signal to the security host 4. Until the user closes the door, the sensing signal of the magnetic reed sensor 61 changes, and the second maintaining signal disappears with the change of the door state, and the extended door opening function is cancelled.

In some embodiments, the user can also send another setting signal by operating the setting device 7 so that the security host 4 sends a release exemption command to the second I/O device 62. According to the canceling non-sending command, the output terminal O2 of the second I/O device 62 will stop outputting the second maintenance signal, so that the input terminal I2 of the second I/O device 62 can obtain the real door state, and thus the extended door opening function is cancelled.

As shown in FIG. 2, the security host 4 is also connected to a warning device 8 in communication. The security host 4 drives the warning device 8 to output a warning in response to the warning signal. The warning can be expressed through sound, light, etc. That is, the warning device 8 is a device that can generate signals such as sound, light, etc., such as a buzzer, a warning light, and the like. In this way, when the door has not been closed for a long time, the warning device 8 can remind the on-site personnel to close the door, reducing safety loopholes. In addition, in the security mode, when the security sensor is triggered or the door detection device 6 detects that the door is open (that is, the corresponding entrance and exit has an abnormal intrusion event), the security host 4 can also drive the warning device 8 to output Warning, remind on-site personnel to be vigilant.

In some embodiments, the security host 4 stores a schedule setting, and the schedule setting has an activation period and an exempt period. During the activation period (for example, during the night without guard period), the security host 4 automatically enters the security mode or release mode according to the detection result of the lock detection device 3 corresponding to the door switch state, and during the exempt period (for example, during the day when there is a guard period), Keep in release mode.

In some embodiments, the access control system may further include a camera (such as a web camera) installed at the entrance and exit, which is connected to the security control center in communication. In this way, when the security control center receives an alarm sent by the security host 4, the security control center can obtain a video and archive from the camera or immediately monitor the entrance site.

In some embodiments, the power supply of the access control system is independent of the power supply of the door lock 1.

In some embodiments, the security host 4 is also communicatively connected with a device status sensor, which can be used to detect the working status of other devices in the field, such as the activation status of the generator and whether the fire alarm is reporting or not. The security host 4 can send this information to the security control center, so that the security control personnel can have a more comprehensive understanding of the on-site situation and can provide immediate assistance.

In summary, the access control system proposed in this creation can automatically set and release security according to the locked state of the entrance and exit, so that the person who wants to pass only needs to perform identity verification once to pass, and automatically release and set security before and after passing. In addition, door position detection can promptly remind on-site personnel to close the door immediately, reducing security loopholes. On the other hand, the extended door opening function can also be activated according to demand, and the time period for automatic setting and security can be scheduled to enable flexibility in use.
