It is suitable for various government departments, such as banks, hotels, computer rooms, armories, offices, intelligent communities, and factories.

[0003] The existing access control system lacks specific control analysis of the operating status of the gate in each access gate. As a result, when the access gate fails, maintenance personnel are required to conduct multiple troubleshooting on the gate.

[0018] Furthermore, each gate in the access control system corresponds to the running status signal of the gate in the current detection period, and the specific analysis process is as follows:

[0019] S11, extracting the displacement data of the gate plates of each gate machine in the access control system corresponding to the current detection period from the operating parameters of the gate plates of each gate machine in the access control system corresponding to the current detection period, and extracting the reference displacement data of the gate plates corresponding to the gate machines from the system storage library;

[0021] Obtain a reasonable displacement difference of a gate plate in a current detection period corresponding to the gate machine. If the displacement difference of a gate plate in a current detection period corresponding to the gate machine is less than or equal to a reasonable displacement difference of a gate plate in a current detection period corresponding to the gate machine, it indicates that the displacement state of the gate plates in the current detection period corresponding to each gate machine in the access control system is normal, and a normal displacement signal of the gate plates in the current detection period corresponding to each gate machine in the access control system is generated, and step S12 is executed. Otherwise, it indicates that the displacement state of the gate plates in the current detection period corresponding to each gate machine in the access control system is abnormal, and an abnormal displacement signal of the gate plates in the current detection period corresponding to each gate machine in the access control system is generated and sent to the early warning module;

[0023] The response speed of the gate plate of each gate machine in the access control system corresponding to the current detection period is subtracted from the reference response speed of the gate plate of the gate machine, and the response speed difference value of the gate plate of each gate machine in the access control system corresponding to the current detection period is obtained, and the absolute value is taken and recorded as the response speed difference value of the gate plate of each gate machine in the access control system corresponding to the current detection period;

[0024] Obtain a reasonable response speed difference value of the gate plate of the gate machine corresponding to the current detection period.

[0026] Compare the current value of the gate drive corresponding to the current detection period of each gate in the access control system with the reference current value of the gate drive corresponding to the gate. If the current value of the gate drive corresponding to the current detection period of the gate is less than or equal to the reference current value of the gate drive corresponding to the gate in the current detection period, it means that the driving state of the gates of each gate in the access control system corresponding to the current detection period is normal, and a normal driving signal of the gates of each gate in the access control system corresponding to the current detection period is generated, and step S14 is executed. Otherwise, it means that the driving state of the gates of each gate in the access control system corresponding to the current detection period is abnormal, and a driving abnormality signal of the gates of each gate in the access control system corresponding to the current detection period is generated and sent to the early warning module;

[0028] The pressure value of the gate plate of each gate machine in the access control system during the current detection period is compared with the pressure value threshold of the gate plate of the gate machine. If the pressure value of the gate plate of each gate machine in the access control system during the current detection period is less than the pressure value threshold of the gate plate, it means that the pressure state of the gate plate of each gate machine in the access control system during the current detection period is normal, and a normal pressure signal of the gate plate of each gate machine in the access control system during the current detection period is generated. Otherwise, it means that the pressure state of the gate plate of each gate machine in the access control system during the current detection period is abnormal, and an abnormal pressure signal of the gate plate of each gate machine in the access control system during the current detection period is generated and sent to the early warning module.

[0029] Furthermore, the access control system includes the following monitoring methods for the personnel entry and exit parameters of each gate corresponding to the current detection period:

[0030] The facial images of the personnel in the current detection period of each gate in the access control system are collected by the CMOS image sensor in the CMOS module to obtain the facial images of the personnel in the current detection period of each gate in the access control system;

[0031] The images of personnel corresponding to the current detection period of each gate in the access control system are divided into two categories: authorized and unauthorized, and the number of entries and exits of authorized personnel corresponding to the current detection period of each gate in the access control system is recorded as the number of entries and exits of authorized personnel corresponding to the current detection period of each gate in the access control system, and the number of entries and exits of unauthorized personnel corresponding to the current detection period of each gate in the access control system is recorded as the number of entries and exits of unauthorized personnel corresponding to the current detection period of each gate in the access control system;

[0033] Furthermore, the personnel entry and exit status signals of each gate in the access control system corresponding to the current detection period are specifically analyzed as follows:

[0034] Obtain the number of authorized personnel entering and exiting, the number of unauthorized personnel entering and exiting, the length of stay of authorized personnel, and the length of stay of unauthorized personnel in each gate of the access control system during the current detection period;

[0035] The number of authorized persons entering and exiting and the length of time the authorized persons stay in each gate in the access control system corresponding to the current detection period are taken as the x-point coordinates and the y-point coordinates in the plane coordinate system, respectively, to obtain the authorized persons entering and exiting state index (x, y) of each gate in the access control system corresponding to the current detection period;

[0036] The number of unauthorized persons entering and exiting and the length of time that unauthorized persons stay in each gate in the access control system corresponding to the current detection period are taken as the x' point coordinates and y' point coordinates in the plane coordinate system, respectively, to obtain the unauthorized persons entering and exiting state index (x', y') of each gate in the access control system corresponding to the current detection period;

[0038] By comparing the personnel entry and exit status coefficient of each gate in the access control system corresponding to the current detection period with the set personnel entry and exit status coefficient threshold of each gate in the access control system corresponding to the current detection period, if the personnel entry and exit status coefficient of each gate in the access control system corresponding to the current detection period is greater than the set personnel entry and exit status coefficient threshold, it means that the personnel entry and exit status of each gate in the access control system corresponding to the current detection period is abnormal, and an abnormal personnel entry and exit status signal of each gate in the access control system corresponding to the current detection period is generated and sent to the early warning module at the same time; otherwise, it means that the personnel entry and exit status of each gate in the access control system corresponding to the current detection period is normal, and a normal personnel entry and exit status signal of each gate in the access control system corresponding to the current detection period is generated.

[0039] Furthermore, the specific warning operation mode of the warning module is as follows:

[0040] When receiving the abnormal displacement signal of the gate plate of each gate machine in the access control system corresponding to the current detection period, the early warning module sends a No. 1 early warning message to the execution terminal;

After filtering and decoding based on the obtained displacement signal, the single displacement data of the gate plate is calculated according to the change of the displacement signal, and the single displacement data of the gate plate of each gate machine in the access control system corresponding to the current detection period is obtained.

[0060] The card reading time of each gate in the access control system corresponding to the current detection period is read by the RFID card reader to obtain the card reading time of each gate in the access control system corresponding to the current detection period, and the start time of the gate movement state of each gate in the access control system corresponding to the current detection period and the stop time of the gate movement state of each gate in the access control system corresponding to the current detection period are obtained by the speed sensor to obtain the start time and end time of the gate opening of each gate in the access control system corresponding to the current detection period, obtain the stroke of the gate fully opened in the access control system corresponding to the current detection period, and obtain the opening stroke of the gate in the access control system corresponding to the current detection period. By calculating the closing time from the card reading time to the gate opening of each gate in the access control system corresponding to the current detection period, the gate opening time of each gate in the access control system corresponding to the current detection period is obtained, and then the gate opening time of each gate in the access control system corresponding to the current detection period is divided by the opening stroke of the gate in the access control system corresponding to the current detection period, and the response speed of each gate in the access control system corresponding to the current detection period is obtained.

[0061] The pressure sensor is used to detect the pressure signal received on the gate surface of each gate in the access control system during the current detection period, and the pressure data of the gate in the access control system during the current detection period are obtained, wherein a number of pressure detection points are evenly distributed on the gate surface of each gate in the access control system during the current detection period.

[0062] The current sensor is used to detect the current signal of the gate drive motor of each gate in the access control system during the current detection period, and the current data of the gate drive motor of each gate in the access control system during the current detection period are obtained.

[0063] The maximum pressure value is selected from the pressure data of each gate in the access control system corresponding to each detection time point in the current detection period as the pressure value of each gate in the access control system corresponding to each detection time point in the current detection period.

[0064] The maximum current value is selected from the current data of the gate drive motor of each gate in the access control system during the current detection period when the gate drive motor is running, as the current value of the gate drive motor of each gate in the access control system during the current detection period when the gate drive motor is running.

[0065] The gate analysis module is used to analyze the operating parameters of the gates of each gate in the access control system corresponding to the current detection period, and obtain the analysis parameters of the gates of each gate in the access control system corresponding to the current detection period. Thus, the operating status of the gates of each gate in the access control system corresponding to the current detection period is analyzed, and the operating status signal of the gates of each gate in the access control system corresponding to the current detection period is obtained. The specific analysis process is as follows:

[0066] S11, extracting the displacement data of the gate plates of each gate machine in the access control system during the current detection period from the operating parameters of the gate plates of each gate machine in the access control system, and extracting the reference displacement data of the gate plates corresponding to the gate machines from the system storage library.

[0067] The single displacement data of the gate plate of each gate machine in the access control system corresponding to the current detection period is subtracted from the single reference displacement data of the gate plate of the gate machine to obtain the single displacement difference of the gate plate of each gate machine in the access control system corresponding to the current detection period, and the absolute value is taken and recorded as the single displacement difference of the gate plate of each gate machine in the access control system corresponding to the current detection period.

[0068] Obtain a reasonable single displacement difference of the gate plate in the current detection period corresponding to the gate machine. If the reasonable single displacement difference of the gate plate in the current detection period corresponding to the gate machine is less than or equal to the reasonable single displacement difference of the gate plate in the current detection period corresponding to the gate machine, it means that the displacement state of the gate plates in the current detection period corresponding to each gate machine in the access control system is normal, and a normal displacement signal of the gate plates in the current detection period corresponding to each gate machine in the access control system is generated, and step S12 is executed. Otherwise, it means that the displacement state of the gate plates in the current detection period corresponding to each gate machine in the access control system is abnormal, and an abnormal displacement signal of the gate plates in the current detection period corresponding to each gate machine in the access control system is generated and sent to the early warning module.

[0069] S12, extracting the response speed of the gate of each gate in the access control system corresponding to the current detection period from the operating parameters of the gate of each gate in the access control system corresponding to the current detection period, and extracting the reference response speed of the gate corresponding to the gate from the system storage library.

[0070] The response speed of the gate plate of each gate machine in the access control system corresponding to the current detection period is subtracted from the reference response speed of the gate plate of the gate machine to obtain the response speed difference of the gate plate of each gate machine in the access control system corresponding to the current detection period, and its absolute value is taken and recorded as the response speed difference of the gate plate of each gate machine in the access control system corresponding to the current detection period.

[0071] Obtain a reasonable response speed difference value of the gate plate of the gate machine corresponding to the current detection period. If the response speed difference value of the gate plate of the gate machine corresponding to the current detection period is greater than or equal to the reasonable response speed difference value of the gate plate of the gate machine corresponding to the current detection period, it indicates that the response state of the gate plates of each gate machine in the access control system corresponding to the current detection period is normal, and a normal response signal of the gate plates of each gate machine in the access control system corresponding to the current detection period is generated, and step S13 is executed. Otherwise, it indicates that the response state of the gate plates of each gate machine in the access control system corresponding to the current detection period is abnormal, and an abnormal response signal of the gate plates of each gate machine in the access control system corresponding to the current detection period is generated and sent to the early warning module.

[0073] Compare the current value of the gate drive corresponding to each gate machine in the access control system in the current detection period with the reference current value of the gate drive corresponding to the gate machine. If the current value of the gate drive corresponding to the gate machine in the current detection period is less than or equal to the reference current value of the gate drive corresponding to the gate machine in the current detection period, it means that the driving state of the gate of each gate machine in the access control system in the current detection period is normal, and a normal driving signal of the gate of each gate machine in the access control system in the current detection period is generated, and step S14 is executed. Otherwise, it means that the driving state of the gate of each gate machine in the access control system in the current detection period is abnormal, and an abnormal driving signal of the gate of each gate machine in the access control system in the current detection period is generated and sent to the early warning module.

[0074] S14, extracting the pressure value of the gate plate of each gate machine in the access control system corresponding to the current detection period from the operating parameters of the gate plate of each gate machine in the access control system, and extracting the pressure value threshold of the gate plate corresponding to the gate machine from the system storage library.

[0075] The pressure value of the gate plate of each gate machine in the access control system during the current detection period is compared with the pressure value threshold of the gate plate of the gate machine. If the pressure value of the gate plate of each gate machine in the access control system during the current detection period is less than the pressure value threshold of the gate plate, it means that the pressure state of the gate plate of each gate machine in the access control system during the current detection period is normal, and a normal pressure signal of the gate plate of each gate machine in the access control system during the current detection period is generated. Otherwise, it means that the pressure state of the gate plate of each gate machine in the access control system during the current detection period is abnormal, and an abnormal pressure signal of the gate plate of each gate machine in the access control system during the current detection period is generated and sent to the early warning module.

The specific analysis process is as follows:

[0083] Extract the number of authorized personnel entering and exiting each gate in the access control system corresponding to the current detection period from the personnel entry and exit parameters of each gate in the access control system corresponding to the current detection period, and obtain the number of authorized personnel entering and exiting each gate in the access control system corresponding to the current detection period;

[0084] Extract the number of unauthorized personnel entering and exiting each gate in the access control system corresponding to the current detection period from the personnel entry and exit parameters of each gate in the access control system corresponding to the current detection period, and obtain the number of unauthorized personnel entering and exiting each gate in the access control system corresponding to the current detection period;

[0085] Extract the stay time of authorized personnel in the current detection period of each gate in the access control system from the personnel entry and exit parameters of each gate in the access control system corresponding to the current detection period, and obtain the stay time of authorized personnel in the current detection period of each gate in the access control system;

[0086] Extract the unauthorized personnel stay time of each gate in the access control system corresponding to the current detection period from the personnel entry and exit parameters of each gate in the access control system corresponding to the current detection period, and obtain the unauthorized personnel stay time of each gate in the access control system corresponding to the current detection period;

[0087] The number of authorized persons entering and exiting and the length of time the authorized persons stay in each gate in the access control system corresponding to the current detection period are taken as the x-point coordinates and the y-point coordinates in the plane coordinate system, respectively, to obtain the authorized persons entering and exiting state index (x, y) of each gate in the access control system corresponding to the current detection period;

[0088] The number of unauthorized persons entering and exiting and the length of time that unauthorized persons stay in each gate in the access control system corresponding to the current detection period are taken as the x' point coordinates and y' point coordinates in the plane coordinate system, respectively, to obtain the unauthorized persons entering and exiting state index (x', y') of each gate in the access control system corresponding to the current detection period;

[0089] Connect the authorized personnel access status index (x, y) of each gate in the access control system corresponding to the current detection period, the unauthorized personnel access status index (x`, y`) of each gate in the access control system corresponding to the current detection period, and the coordinate points (x, 0) and (x`, 0) clockwise to draw a quadrilateral, obtain the area of ​​the drawn quadrilateral, and use it as the personnel access status coefficient of each gate in the access control system corresponding to the current detection period.

[0090] By comparing the personnel entry and exit status coefficient of each gate in the access control system corresponding to the current detection period with the set personnel entry and exit status coefficient threshold of each gate in the access control system corresponding to the current detection period, if the personnel entry and exit status coefficient of each gate in the access control system corresponding to the current detection period is greater than the set personnel entry and exit status coefficient threshold, it means that the personnel entry and exit status of each gate in the access control system corresponding to the current detection period is abnormal, and an abnormal personnel entry and exit status signal of each gate in the access control system corresponding to the current detection period is generated and sent to the early warning module at the same time; otherwise, it means that the personnel entry and exit status of each gate in the access control system corresponding to the current detection period is normal, and a normal personnel entry and exit status signal of each gate in the access control system corresponding to the current detection period is generated.

[0091] It should be noted that, under normal circumstances, the number of times authorized personnel enter and exit and the length of time authorized personnel stay at each gate in the access control system corresponding to the current detection period are relatively stable, while the number of times unauthorized personnel enter and exit and the length of time unauthorized personnel stay at each gate in the access control system corresponding to the current detection period are relatively unstable. Therefore, the greater the number of times unauthorized personnel enter and exit and the length of time unauthorized personnel stay at each gate in the access control system corresponding to the current detection period, the more abnormal the entry and exit status of personnel at each gate in the access control system corresponding to the current detection period is.

[0092] As a preferred solution, the present invention monitors and analyzes the personnel entry and exit parameters of each gate in the access control system corresponding to the current detection period, thereby analyzing the abnormal personnel entry and exit parameters of each gate in the access control system corresponding to the current detection period, so as to intuitively understand the personnel entry and exit situation of each gate in the access control system, avoid the illegal personnel passing through the gates in the access control system without effective monitoring and management, provide accurate information data for subsequent identity analysis and verification, and significantly improve the control and management security of each gate in the access control system.

[0093] The early warning module is used to perform corresponding early warning operations based on the running status signals of the gate plates in the current detection period corresponding to each gate in the access control system and the personnel entry and exit status signals of each gate in the access control system corresponding to the current detection period. The specific early warning operation methods are as follows:

[0094] When receiving the abnormal displacement signal of the gate plate of each gate machine in the access control system corresponding to the current detection period, the early warning module sends a No. 1 early warning message to the execution terminal.

[0095] When receiving the abnormal response signal of the gate plate of each gate machine in the access control system corresponding to the current detection period, the early warning module sends a second early warning message to the execution terminal.

[0096] When receiving the abnormal driving signal of the gate plate of each gate machine in the access control system corresponding to the current detection period, the early warning module sends a No. 3 early warning message to the execution terminal.

[0097] When receiving the abnormal pressure signal of the gate plate of each gate machine in the access control system corresponding to the current detection period, the early warning module sends a No. 4 early warning message to the execution terminal.

[0098] When receiving abnormal signals of personnel access status of gates corresponding to the current detection period in each gate machine in the access control system, the early warning module sends a No. 5 early warning message to the execution terminal.

[0099] The execution terminal is used to perform corresponding execution operations based on the warning information sent by the warning module of the access control system. The specific operation methods are as follows:

[0100] When receiving the No. 1 warning information sent by the warning module, the maintenance personnel are arranged to inspect and handle the displacement status of the gate plates corresponding to each gate in the access control system.

[0101] When receiving the No. 2 warning information sent by the warning module, the maintenance personnel are arranged to inspect and handle the response status of the gate plates corresponding to each gate in the access control system.

[0102] When the No. 3 warning information sent by the warning module is received, the maintenance personnel are arranged to inspect and handle the driving status of the gate plates corresponding to each gate in the access control system.

[0103] When the No. 4 warning information sent by the warning module is received, the maintenance personnel are arranged to inspect and handle the pressure status of the gate plates corresponding to each gate in the access control system.

[0104] When receiving the No. 5 warning information sent by the warning module, the maintenance personnel are arranged to check the personnel access status corresponding to each gate in the access control system.

[0105] The system repository is used to store the reference displacement data of the gate corresponding to the gate machine, the reference response speed, the reference current value of the gate drive, and the pressure value threshold of the gate.

[0106] The above formulas are all dimensionless and numerical calculations. The formula is a formula that is obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation. The size of the coefficient is to quantify each parameter to obtain a specific value. Regarding the size of the coefficient, it is acceptable as long as it does not affect the proportional relationship between the parameter and the quantified value.
