Description

Technical Field

[0001] The present invention relates to the technical field of intelligent access control in the electric power industry, and in particular to a system for realizing remote switching of access control equipment at each station end based on an intelligent access control service. Background Art

[0002] In the access control system of the power industry, the remote switch system is an important means of controlling the access of unauthorized and temporary personnel when there are no on-duty personnel at each station. In the remote control of the access control platform or monitoring platform, the switch status of the access control equipment can be remotely managed, the access to the site can be monitored in real time, and the identity can be remotely verified to ensure that only authorized personnel can enter, ensuring the safety and stable operation of power facilities. At present, the common solution is that the terminal equipment system deployed at the station directly connects to the access control equipment, and then the terminal equipment system connects to the access control platform. However, most of the existing substation access control controllers, face recognition integrated machines and other access control devices come from different manufacturers, and the protocol standards are not unified, which makes it difficult for the terminal equipment system to adapt to all access control devices. In addition, this secondary docking mode through the terminal equipment system requires the purchase of terminal equipment systems in addition to access control equipment, which increases costs. The terminal link itself increases the difficulty of troubleshooting when problems are encountered during implementation. Due to the complex docking relationship, it also brings challenges to the operation, upgrade and maintenance of the system.

[0003] In the power industry, remote door opening and closing systems and video surveillance systems have been widely adopted. Although they can strengthen the monitoring and security management of people entering and leaving, when reviewing and checking the entry and exit records, it is necessary to watch the video footage of the door opening moment to confirm the person, and it is usually necessary to call the monitoring playback function; for short-term situations, it is feasible to use video playback to confirm the entry and exit of people; if the time is long, such as more than one year, a large amount of hard disk capacity is required to store video recording data; for scenes with large personnel flow, the process of checking and confirming the entry and exit of people is relatively complicated and takes more time; for this reason, the applicant proposes a system based on intelligent access control services to realize remote opening and closing of access control equipment at each station, which can modulate and demodulate the protocol standards of different access control equipment, be compatible with access control equipment, simplify the access control system docking process, improve system stability and security, optimize operation and maintenance management and upgrade maintenance processes, realize remote real-time monitoring and recording functions, and quickly review and confirm the information of people entering and leaving; it brings more convenient solutions for the safe and effective management of access control systems in the power industry. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a system for remotely switching on and off the access control equipment at each station based on an intelligent access control service. The system is configured with an access control platform, an intelligent access control service, access control equipment and a real-time monitoring camera. The system modulates and demodulates the protocol standards of different access control equipment, is compatible with access control equipment, simplifies the access control system docking process, improves system stability and security, optimizes operation and maintenance management and upgrades the maintenance process, realizes remote real-time monitoring and recording functions, and quickly reviews and confirms the information of people entering and leaving the system. This provides a more convenient solution for the safe and effective management of the access control system in the power industry.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A system for remotely opening and closing access control equipment at each station end based on intelligent access control service includes an access control platform, an intelligent access control service, access control equipment and a real-time monitoring camera, characterized in that: the access control platform of the system for remotely opening and closing access control equipment at each station end based on the intelligent access control service provides real-time monitoring and display of doors, door opening and closing record viewing and equipment management functions; the intelligent access control service is composed of an instruction processing module, a capture module, a drive allocation module and a drive; the access control equipment includes an access control controller, a face integrated machine and an access control integrated machine; the real-time monitoring camera is used for real-time monitoring and confirmation of people entering and leaving, and real-time capture and storage; specifically: the access control platform:

[0007] The device management at the front end of the access control platform can view and set detailed information of the access control device, including the device name, corresponding protocol number, IP, port, user name, password, serial number and other information. This information corresponds to the device table in the database. The access control device management should also be able to view and configure the door, including the name of the door, the bound surveillance camera and the node association of the device, etc. It can cope with the situation where one device corresponds to multiple doors. For the surveillance camera bound to the door, the camera IP, port, user name, password, channel number, camera manufacturer and other necessary information for connecting to the camera can be configured. This information corresponds to the door table in the database.

[0008] The backend of the access control platform connects to the access control service through MQTT, HTTP and other methods, sends door opening and closing instructions to the access control service, and receives the door opening results returned by the access control service; after clicking the door control button in the real-time door monitoring on the front end of the platform, the backend of the platform will send instructions to the intelligent access control service, including the door ID number, control type and other information; the prompt of the current issued instruction can be displayed, such as clicking to open the door, the prompt "Door opening has been issued, the issuance time is a certain year, month, day, hour, minute, second, waiting for service reply"; after receiving the door opening control success result returned by the access control service, the prompt becomes "Door opening has been successfully executed, the execution time is a certain year, month, day, hour, minute, second".

[0009] Smart access control service:

[0010] The intelligent access control service consists of a command processing module, a capture module, a driver allocation module, and a driver;

[0011] The instruction processing module is connected to the access control platform via MQTT, HTTP, etc. After receiving the instruction sent by the platform, it analyzes and determines it, and then sends the instruction to the driver allocation module after confirmation;

[0012] The capture module is responsible for capturing images and provides a capture calling interface. When the camera's IP, port, user name, password, channel number, preset position to be adjusted and other parameters are input, the capture module will call the corresponding capture interface, return the real-time snapshot of the door opening and closing, save it locally and generate an HTTP access URL for the caller to use;

[0013] The driver allocation module is responsible for managing the driver, including opening, closing, and command allocation of the driver. It is the middleware between the command processing module and the driver. When starting the service, the driver allocation module will read the information in the device table and start the corresponding driver or load the device according to the protocol number. After receiving the instruction issued by the command processing module, the driver allocation module finds the corresponding device information such as device ID number, device protocol number, etc. according to the door ID number, and then selects the corresponding driver to issue the instruction accordingly.

[0014] The driver is connected to the device based on the IP network protocol of the access control device. Each driver is a separate module and implements only one protocol. Different protocols are connected to different drivers. Each driver corresponds to a unique protocol number. The protocol number is determined when the driver is developed. The corresponding driver can be found according to the protocol number.

[0015] Access control equipment:

[0016] Access control devices are access control devices from any manufacturer, including access control controllers, facial recognition integrated devices, access control integrated devices, etc. If the device models are different but the protocols are the same, in this case, only one supporting driver is needed, and no secondary driver development is required. In special cases, if the device is not connected but the terminal system deployed on the station side, only an IP network-based protocol needs to be provided, and the access control service driver can also be connected; although the current access control device protocols of various manufacturers are not unified, the functions of remote door control and door event status collection and reporting are almost essential basic functions of the access control controllers of various manufacturers, and the access control service driver only needs to be connected according to the protocol;

[0017] Real-time surveillance camera:

[0018] Real-time monitoring cameras are used to monitor the door in real time to confirm the entry and exit of people. They support the calling interface or protocol of real-time capture and storage, so that the access control service capture module can capture photos of the moment of entering and exiting the door, which can be convenient for later review and inspection of entry and exit records. You only need to click a button in the door opening and closing records of the access control platform to view it. The real-time monitoring camera is placed facing the entrance and exit to capture pictures at the fastest speed. The linkage calling of the camera preset position will take a short time. The real-time monitoring camera monitors multiple locations, so it is installed and placed farther away to leave two or three seconds for calling the preset position.

[0019] Furthermore, the door real-time monitoring at the front end of the access control platform can visualize the access control equipment, with buttons for opening and closing the door that can be clicked, and the real-time monitoring screen of the door from the camera bound to the door can be viewed; the real-time switch status of the door can be displayed, and the real-time switch status of the door is collected, updated and reported by the access control service; the front end of the access control platform can display the door opening event, which is read from the event table of the database and used to display the remote door opening record, which should include the door name, update time, operator, door opening and closing type, etc. There is a details button behind each door opening record, which can be clicked to view the camera snapshot picture at the moment when the door is opened or closed successfully, and observe the on-site picture of people entering and leaving the door;

[0020] Furthermore, the front end of the access control platform can be accessed at the main station or at the station end, and is not limited to the main station or the monitoring center. If there are sufficient personnel, the door can be controlled at the station end; if there are insufficient personnel, the door can be controlled at the main station or the monitoring center.

[0021] Furthermore, the intelligent access control service can modulate and demodulate the protocol standards of different access control devices, be compatible with access control devices, simplify the access control system docking process, improve system stability and security, optimize operation and maintenance management and upgrade maintenance processes, realize remote real-time monitoring and recording functions, and quickly review and confirm the information of people entering and leaving.

[0022] Furthermore, the driver in the smart access control service will collect the status, events and other information of the device in real time. After receiving the assigned instructions, the driver will send the instructions to the device. After receiving the instructions, the device will execute the instructions and reply with the execution results. After receiving the reply, the driver will transfer the results to the driver allocation module, the driver allocation module will transfer the results to the instruction processing module, and the instruction processing module will report the results to the access control platform backend.

[0023] Furthermore, the computer that deploys the access control service in the smart access control service configures an HTTP image service. When clicking the details button of the door opening event on the front end of the access control platform, the image will be accessed according to the HTTP URL of the record in the database, so that the real-time image of the moment of opening and closing the door can be viewed. The HTTP image service can freely select a suitable one.

[0024] Furthermore, in addition to docking devices, the driver in the smart access control service can also dock terminals and access control systems of other manufacturers, and only needs to provide a protocol based on the IP network.

[0025] The benefits of this application are:

[0026] 1. High compatibility;

[0027] The system can connect to most of the access control devices on the market that support TCP / IP protocol, and has high expansion compatibility;

[0028] 2. Convenience;

[0029] At present, many solutions for access control docking in the conventional power industry need to be implemented through the access control terminal system. This system does not require secondary docking with the terminal system, which is more convenient.

[0030] 3. High efficiency;

[0031] The driver of the intelligent access control service connects to the device according to the protocol based on the IP network of the access control device. Each driver is a separate module and implements only one protocol. Different protocols are connected to different drivers. Each driver corresponds to a non-repetitive protocol number. The protocol number is self-defined during driver development. The corresponding driver can be found according to the protocol number. It simplifies the system architecture and completely gets rid of the dependence on the secondary connection of the terminal device system deployed on the station side, reduces the system complexity, improves the module stability, is more convenient to implement, and has higher processing efficiency.

[0032] 4. Lightweight data storage;

[0033] The system simplifies data storage by only capturing the image at the moment the door is opened. This image is used to verify entry and exit through the image on the platform's door opening record page. The access control service automatically calls the surveillance camera capture interface to obtain the image, making its data lightweight and effectively reducing data storage requirements.

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0041] like Figure 1-6 As shown, a system for remotely switching on and off access control devices at each station based on intelligent access control services is shown, including an access control platform, intelligent access control services, access control devices and real-time monitoring cameras, such as Figure 4 As shown, the access control platform based on the intelligent access control service to realize remote opening and closing of the access control equipment system at each station provides real-time door monitoring display, door opening and closing record viewing and equipment management functions; the intelligent access control service is composed of a command processing module, a capture module, a drive allocation module and a driver; the access control equipment includes an access control controller, a face recognition integrated machine and an access control integrated machine; the real-time monitoring camera is used for real-time monitoring and confirmation of people entering and leaving, and real-time capture and storage; specifically:

[0042] Access control platform:

[0043] The device management at the front end of the access control platform can view and set detailed information of the access control device, including the device name, corresponding protocol number, IP, port, user name, password, serial number and other information. This information corresponds to the device table in the database. The access control device management should also be able to view and configure the door, including the name of the door, the bound surveillance camera and the node association of the device, etc. It can cope with the situation where one device corresponds to multiple doors. For the surveillance camera bound to the door, the camera IP, port, user name, password, channel number, camera manufacturer and other necessary information for connecting to the camera can be configured. This information corresponds to the door table in the database.

[0044] The front end of the access control platform monitors the doors in real time and displays the access control equipment visually. There are buttons for opening and closing the doors that can be clicked, and the real-time monitoring screen of the doors from the cameras bound to the doors can be viewed. The real-time open and close status of the doors can be displayed, which is collected, updated and reported by the access control service. The front end of the access control platform can display the door opening events, which are read from the event table of the database and used to display the records of remote door opening, which should include the door name, update time, operator, door opening and closing type, etc. There is a details button behind each door opening record. Click it to view the camera snapshot picture at the moment when the door is opened or closed successfully, and observe the on-site situation when people enter and exit the door.

[0045] The backend of the access control platform connects to the access control service through MQTT, HTTP and other methods, sends door opening and closing instructions to the access control service, and receives the door opening results returned by the access control service; after clicking the door control button in the real-time door monitoring on the front end of the platform, the backend of the platform will send instructions to the intelligent access control service, including the door ID number, control type and other information; the prompt of the current issued instruction can be displayed, such as clicking to open the door, the prompt "Door opening has been issued, the issuance time is a certain year, month, day, hour, minute, second, waiting for service reply"; after receiving the door opening control success result returned by the access control service, the prompt becomes "Door opening has been successfully executed, the execution time is a certain year, month, day, hour, minute, second".

[0046] Smart access control service:

[0047] The intelligent access control service consists of a command processing module, a capture module, a driver allocation module, and a driver;

[0048] The instruction processing module is connected to the access control platform via MQTT, HTTP, etc. After receiving the instruction sent by the platform, it analyzes and determines it, and then sends the instruction to the driver allocation module after confirmation;

[0049] The capture module is responsible for capturing images and provides a capture calling interface. When the camera's IP, port, user name, password, channel number, preset position to be adjusted and other parameters are input, the capture module will call the corresponding capture interface, return the real-time snapshot of the door opening and closing, save it locally and generate an HTTP access URL for the caller to use;

[0050] The driver allocation module is responsible for managing the driver, including opening, closing, and command allocation of the driver. It is the middleware between the command processing module and the driver. When starting the service, the driver allocation module will read the information in the device table and start the corresponding driver or load the device according to the protocol number. After receiving the instruction issued by the command processing module, the driver allocation module finds the corresponding device information such as device ID number, device protocol number, etc. according to the door ID number, and then selects the corresponding driver to issue the instruction accordingly.

[0051] The driver is connected to the device based on the IP network protocol of the access control device. Each driver is a separate module and implements only one protocol. Different protocols are connected to different drivers. Each driver corresponds to a unique protocol number. The protocol number is determined when the driver is developed. The corresponding driver can be found according to the protocol number. For example, in the device management configuration of the front end of the access control platform, the protocol number of a certain access control controller is 3. When the service is started, the driver allocation module can find the corresponding driver according to the protocol number and load the device, which is easy to expand the connection.

[0052] This design method simplifies the system architecture, completely gets rid of the reliance on secondary docking of the terminal equipment system deployed at the station end, reduces system complexity, improves module stability, and is more convenient to implement; if there is a problem with a driver, the relevant driver can be quickly located and solved according to the protocol, without affecting other drivers. At the same time, it is also convenient for system expansion, providing a more flexible and efficient solution for the deployment and maintenance of access control systems in the power industry;

[0053] The driver shown will collect the status, events and other information of the device in real time. After receiving the assigned instructions, the driver will send the instructions to the device. After receiving the instructions, the device will execute the instructions and reply the execution results. After receiving the reply, the driver will transfer the results to the driver allocation module, which will transfer the results to the instruction processing module. The instruction processing module will report the results to the back end of the access control platform. After the device successfully opens (closes) the door, an opening (closing) door event will be generated. After the driver collects and obtains the newly added opening (closing) door event of the device, it will transfer the event to the driver allocation module. The driver allocation module finds the corresponding door according to the device ID and the door node number, and then captures the picture first and then transfers it. The capture calls the capture module, and the parameters such as the camera corresponding to the capture are passed into the capture interface. After the capture is completed, the HTTP URL for the access control platform to access and view the picture will be returned, and the door event and URL will be transferred to the instruction processing module together. The instruction processing module stores the relevant information of the event such as door name, update time, operator, door opening and closing type, URL, etc. in the database, and the event of successful door control can be seen on the platform.

[0054] The computer that deploys the access control service is configured with HTTP image service. Clicking the details button of the door opening event on the front end of the access control platform will access the image according to the HTTP URL of the record in the database, so that the real-time image of the moment of opening and closing the door can be viewed. The HTTP image service is not an invention of this patent, and you can freely choose a suitable one;

[0055] The driver shown will obtain the door switch status of the device in real time. When the device opens the door, the door status will be collected and transferred to the instruction processing module through the driver allocation module. The instruction processing module updates the door status to the database and reports it to the back end of the access control platform. The platform reads the database, analyzes the reported data, and the real-time door open (closed) status can be seen on the front end of the platform. In addition to docking devices, the driver can also dock terminals and access control systems of other manufacturers. It only needs to provide protocols based on IP networks. Access control devices:

[0056] Access control devices are access control devices from any manufacturer, including access control controllers, facial recognition integrated devices, access control integrated devices, etc. If the device models are different but the protocols are the same, in this case, only one supporting driver is needed, and no secondary driver development is required. In special cases, if the device is not connected but a terminal system deployed on the station side, only an IP network-based protocol needs to be provided, and the access control service driver can also be connected; although the current access control device protocols are not unified among manufacturers, the functions of remote door control and door event status collection and reporting are almost essential basic functions of access control controllers from various manufacturers, and the access control service driver only needs to be connected according to the protocol; some manufacturers will also encapsulate the protocol and provide a docking SDK library;

[0057] Real-time surveillance camera:

[0058] Real-time monitoring cameras are used to monitor the door in real time to confirm the entry and exit of people. They support the calling interface or protocol of real-time capture and storage, so that the access control service capture module can capture photos of the moment of entering and exiting the door, which can be convenient for later review and inspection of entry and exit records. You only need to click a button in the door opening and closing records of the access control platform to view it. The real-time monitoring camera is placed facing the entrance and exit to capture pictures at the fastest speed. The linkage calling of the camera preset position will take a short time. The real-time monitoring camera monitors multiple locations, so it is installed and placed farther away to leave two or three seconds for calling the preset position.

[0059] The smart access control service shown can modulate and demodulate the protocol standards of different access control devices, be compatible with access control devices, simplify the access control system docking process, improve system stability and security, optimize operation and maintenance management and upgrade maintenance processes, realize remote real-time monitoring and recording functions, and quickly review and confirm the information of people entering and leaving.

[0060] like Figure 1 As shown, the access control service and access control platform are deployed in the monitoring center or the main station, and the access control devices such as the access control controller and the face recognition integrated machine are deployed at the station end. The access control service is connected to the back end of the access control platform through the instruction processing module, and is connected to the access control device through the driver. The access control devices at each station end need to communicate with the access control service network. If they are not in the same network segment, port mapping can be done;

[0061] The duty personnel of the monitoring center and the station end can access the access control platform at the monitoring center or each station end, click the open / close button for the door that needs to be controlled on the platform, and the back end of the access control platform will send the door control command of opening / closing the door to the access control service. After the service instruction processing module receives the instruction, it will be transferred to the corresponding driver through the driver allocation module, and then sent to the device through the docking driver. After receiving the instruction, the device executes the instruction and then replies to the driver instruction execution result. The driver transfers the received result to the instruction processing module through the driver allocation module. The instruction processing module reports the platform door control result, and then the duty personnel can see the result of this door control on the platform.

[0062] like Figure 2 As shown, in the device event reporting process shown, after the device executes door control, if the control execution is successful, an access control event will be generated. The access control service either discovers new events through real-time query and queries new events, or the device protocol or SDK actively reports the event. After the driver receives the new event returned by the device, it will transfer the event-related information such as the event occurrence time, door opening and closing type, door node number, etc. to the driver allocation module. The driver allocation module will find the camera information bound to the door according to the device ID number and the door node number, and call the capture module accordingly to capture and save the picture, and then transfer the return URL and event-related information to the instruction processing module. The instruction processing module stores the access control event in the event table in the database;

[0063] The access control platform checks the door opening event, reads the information in the database event table for record display, so that the on-duty personnel can check the door opening event and click the details button. The platform will obtain the real-time snapshot picture from the HTTP service according to the HTTP URL in the database for display, so that the on-duty personnel can see the real-time snapshot picture of the door opening and closing; if the door control fails for some reason or the device is offline, no new record will appear, and a new record will definitely appear if the door control is successful.

[0064] like Figure 3 As shown, it is a schematic diagram of updating the door opening and closing status of the access control device. The access control service either obtains the latest door status by real-time query of the door status, or the device protocol or SDK actively reports the door status. After the driver receives the door status returned by the device, when the door status changes, it will be transferred to the instruction processing module through the driver allocation module. The instruction processing module reports the door status to the back end of the access control platform and then puts it into storage; after the on-duty personnel issue a door control order at the real-time door monitoring of the access control platform, if the platform receives the door status change reported by the access control service, it will update the door status in the real-time monitoring of the door to open or close, or the platform refreshes the page to re-read the door status in the database door table to display the real-time switch status of the door.

[0065] like Figure 5 As shown, it is a specific implementation diagram of a site. The backend of the access control platform, the intelligent access control service, the http image service, and the database are all deployed in the monitoring center or the main site. The access control service directly connects to the access control device at the site through the IP network, without the need for secondary connection with the terminal device system, which is easy to implement.

[0066] like Figure 6As shown, when the access control service is deployed at the main station or monitoring center, a schematic diagram of connecting multiple stations is shown. The back end of the access control platform and the intelligent access control service are deployed at the monitoring center or the main station, and the on-duty personnel at each station can access the platform at the station. It can be seen from the figure that the access control service connects to devices of different models and protocols from various manufacturers under multiple stations, and is compatible with various access control devices in the case of inconsistent standards. At the same time, it simplifies the access control system connection process, reduces hardware costs and operation and maintenance costs, is easy to implement, and the system is more stable and secure.

[0067] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.

Access control equipment: The access control equipment is any manufacturer's access control equipment, including access control controllers, face recognition integrated machines, and access control integrated machines. If the device models are different but the protocols are the same, in this case, only one supporting driver is needed, and no secondary driver development is required. In special cases, if the docking is not a device but a terminal system deployed on the station side, only an IP network-based protocol needs to be provided, and the access control service driver can also be docked. Although the current access control equipment protocols of various manufacturers are not unified, the functions of remote door control and door event status collection and reporting are almost essential basic functions of access control controllers of various manufacturers. The access control service driver only needs to be docked according to the protocol. Real-time surveillance camera: Real-time monitoring cameras are used to monitor the door in real time to confirm the entry and exit of people. They support the calling interface or protocol of real-time capture and storage, so that the access control service capture module can capture photos of the moment of entering and exiting the door, which can be convenient for later review and inspection of entry and exit records. You only need to click a button in the door opening and closing records of the access control platform to view it. The real-time monitoring camera is placed facing the entrance and exit to capture pictures at the fastest speed. The linkage calling of the camera preset position will take a short time. The real-time monitoring camera monitors multiple locations, so it is installed and placed farther away to leave two or three seconds for calling the preset position.

2. According to claim 1, a system for remotely opening and closing access control equipment at each station based on intelligent access control service, characterized in that: The front end of the access control platform monitors the doors in real time and displays the access control equipment visually. There are buttons for opening and closing the doors that can be clicked, and the real-time monitoring screen of the door from the camera bound to the door can be viewed. The real-time switch status of the door can be displayed, and the real-time switch status of the door is collected, updated and reported by the access control service. The front end of the access control platform can display the door opening event, which is read from the event table of the database and used to display the record of remote door opening, which should include the door name, update time, operator, and door opening and closing type. There is a details button behind each door opening record. Click it to view the camera capture picture at the moment when the door is opened or closed successfully, and observe the on-site picture when people enter and exit the door.

According to claim 1, a system for remotely opening and closing access control equipment at each station based on intelligent access control service, characterized in that: The intelligent access control service can modulate and demodulate the protocol standards of different access control devices, be compatible with access control devices, simplify the access control system docking process, improve system stability and security, optimize operation and maintenance management and upgrade maintenance processes, realize remote real-time monitoring and recording functions, and quickly review and confirm the information of people entering and leaving.

4. According to claim 1, a system for remotely opening and closing access control equipment at each station based on intelligent access control service, characterized in that: The driver in the smart access control service will collect the status and event information of the device in real time. After receiving the assigned instructions, the driver will send the instructions to the device. After receiving the instructions, the device will execute the instructions and reply with the execution results. After receiving the reply, the driver will transfer the results to the driver allocation module, the driver allocation module will transfer the results to the instruction processing module, and the instruction processing module will report the results to the access control platform backend.

5. According to claim 1, a system for remotely opening and closing access control equipment at each station based on intelligent access control service, characterized in that: The computer that deploys the access control service in the smart access control service is configured with an HTTP image service. When clicking the details button of the door opening event on the front end of the access control platform, the image will be accessed according to the HTTP URL of the record in the database, so that the real-time image of the moment of opening and closing the door can be viewed. The HTTP image service can freely select the appropriate one.

6. According to claim 1, a system for remotely opening and closing access control equipment at each station based on intelligent access control service, characterized in that: In addition to docking devices, the driver in the smart access control service can also dock terminals and access control systems of other manufacturers, and only needs to provide a protocol based on the IP network.
