Description

Technical Field

[0001] The present invention relates to the field of electric communication technology, in particular to a remote access control system, which aims to improve the evacuation efficiency and safety in emergency situations such as fire. Background Art

[0002] In today's society, large crowded places such as shopping malls, schools, airports and stations generally adopt a strategy of centralized management of main entrances and exits in order to improve management efficiency and maintain order, while other safety exits are restricted through access control systems or locking methods. This strategy does simplify the management process in daily operations, but it also hides major safety hazards. Especially in emergency situations, such as when a fire occurs, it is extremely difficult and time-consuming to manually open these exits because management personnel are usually not near the restricted safety exits. Many examples have shown that if the safety exits cannot be opened in time, the risk of casualties will be greatly increased.

[0003] At present, there are several key problems in the current social situation that need to be solved urgently: First, the access barriers caused by access control and locking mechanisms are significant. Although some building designs adopt emergency measures such as fire linkage to cut off power supply to disable access control, a large number of buildings have not yet installed automatic fire alarm systems. Even if relevant systems are installed, there is a risk of linkage failure or response delay. Secondly, there is a significant contradiction between management needs and safety needs. An access control system that can meet daily management needs (no need to lock, while preventing people from entering and exiting at will) and can be opened quickly and safely in an emergency has become an urgent need. Furthermore, the existing access control systems generally lack remote wireless opening and status display functions, resulting in slow emergency response, and the complexity of the lines and long distances increase the difficulty of maintenance and management. In addition, as the core of 24-hour monitoring, the human resources of the fire control room have not been fully utilized in the existing access control system to improve the overall safety efficiency. Finally, the current wireless smart fire protection technology mainly stays in the alarm stage, and there is still a lack of terminal equipment that can effectively link with the access control system. Summary of the invention

[0004] In view of the problems existing in the above-mentioned background technology, the present invention proposes an innovative access control opening system, which aims to effectively replace the traditional locking method and solve the problem of access control linkage failure, thereby improving the security management level of large and crowded places.

[0005] Technical solution: The door opening system of the present invention remains in a closed state under normal working conditions, which is equivalent to the traditional locking function, but it incorporates advanced intelligent technology. When the automatic fire alarm system fails to effectively cut off the power supply and open the door for some reason, the staff of the fire control room can quickly use the newly added automatic and manual remote opening functions to wirelessly operate the door control system to achieve rapid opening of the door and receive feedback signals on the door opening and closing status in real time. This design not only enhances the emergency response capability of the access control system, but also improves the overall safety efficiency. Technical Effects

[0006] Double protection: The present invention provides a strong opening protection for the evacuation door which needs to be locked for daily management and needs to be quickly escaped in case of fire, which not only meets the daily management needs, but also ensures the safe evacuation in emergency situations.

[0007] Remote control and status display: The functions of remote wireless access control and real-time display of access control opening and closing status overcome the defects of traditional access control systems such as complex lines, long distances, and difficult maintenance and management, and improve the reliability and ease of use of the system.

[0008] Wide applicability: Regardless of whether the building is equipped with an automatic fire alarm system, the present invention can be installed and used, effectively solving the problem of inconvenience in manual opening after locking, and expanding the application scope of the system.

[0009] Resource integration and efficiency improvement: Taking full advantage of the fact that the fire control room is staffed 24 hours a day, the safety efficiency and emergency response speed are significantly improved by integrating human resources and intelligent technology.

[0010] Centralized control and intelligent linkage: One access control host can control almost all fire partition access control devices in large and long-distance places, which is simple and efficient to operate. At the same time, the present invention can be linked with the intelligent fire protection system to solve the problem that the alarm information cannot be linked with the local access control after being uploaded to the cloud, thus realizing real intelligent management.

[0011] Solution for places without fire alarm system: For places without automatic fire alarm system but need to improve the effectiveness and timeliness of door opening, the present invention provides a good solution to ensure the timely opening of door under fire conditions.

[0012] Cloud-based smart fire protection linkage: This invention realizes the linkage function with the cloud-based smart fire protection system, further improving the overall safety level and emergency response capabilities.

[0013] In summary, the present invention provides a new door opening system that integrates the convenience of daily management and the safety in emergency situations, which provides strong support for the safety management of large-scale crowded places and has significant social benefits and practical value. System composition.

[0014] Access control: The access control part uses an electronic door lock or a magnetic device to control the opening and closing of the evacuation door. When the access control switch in the access control controller is powered on, the access control is closed; when the power is off, the access control is opened. The contact number of the fire control room and the contact information of the person with management authority will be posted on the door, so that in an emergency, the personnel can quickly get in touch with the fire control room staff or the management personnel with the authority to open the access control.

[0015] The access controller is one of the core components of the access control system, and is responsible for receiving, processing and transmitting instructions. It can not only receive the opening or closing signal from the remote access control host and send corresponding control instructions to the access control, but also monitor the opening and closing status of the door in real time to ensure the stable operation of the access control system. Core functions and installation location: The main function of the access controller is to receive and respond to the instructions of the remote access control host, and connect to the access control through a wired connection to achieve precise control of it. At the same time, it is also responsible for receiving the status information of the door opening and closing signal switch, and transmitting this information to the access control host in real time, so that the host can accurately grasp the working status of the access control. In order to ensure the stability and timeliness of signal transmission, the access controller is usually installed near the controlled door. The access controller has four built-in functional modules, which work together to achieve efficient and intelligent access control management. Antenna module: The antenna is the key to ensure reliable signal transmission. In some indoor places, the wireless signal may not be effectively delivered due to interference from building structures or environmental factors. At this time, the antenna can be introduced into open areas such as outdoors to ensure unimpeded communication between the access controller and the access control host. Internet of Things module: This module is responsible for signal collection and transmission. It can not only receive the status information of the door opening and closing signal switch and feed it back to the access control host, but also convert the digital or analog signal sent by the host into an electrical signal, and convert it into a current on-off signal for the access control through the access control power supply, so as to realize the opening and closing of the access control. Access control power supply: Provide stable and reliable power support for the access controller and the controlled equipment to ensure that it can work continuously and stably. Intercom and broadcast module: This module plays a vital role in emergency situations. When someone presses the access control special alarm button, the access controller will immediately start the alarm evacuation sound to remind people to evacuate quickly, and at the same time prompt the staff to get in touch with the fire control room so as to open the access control in time and ensure the safe evacuation of people. Fire control room staff can achieve voice communication between the fire control room and the evacuation door through the dialogue and broadcast module.

[0016] The access controller can not only receive and process instructions from the remote access control host, but also respond in an emergency. For example, in a place where there is no fire alarm system and smart fire linkage or the linkage fails, personnel can trigger an emergency response by pressing the dedicated access alarm button. After receiving this signal, the access controller will immediately send the information to the access control host and start the alarm evacuation sound. After seeing the alarm information, the staff in the fire control room can quickly open all the access control in the fire area to ensure the safe evacuation of personnel. At the same time, authorized managers can also remotely operate to open the access control of the corresponding alarm place through the user operation interface such as mobile phone APP to achieve fast and accurate emergency response.

[0017] IoT module: It is a signal transmission device, which can be a remote wireless transmission module such as 4G, 5G, LORA, WiFi, etc. It transmits the opening and closing instructions of the remote access control host to the access controller. And it converts the electrical signal of the door opening and closing into a digital or analog signal and wirelessly feeds it back to the remote access control host.

[0018] The access control host mainly includes the following functions: Command control and status monitoring: The host can accurately send opening or closing commands to the access control controller, and collect and process the working status signals of the access control in real time. After processing, the information will be displayed on the host screen in a clear and intuitive way. Whether it is open or closed, it is clear at a glance. Inspection and programming: The host has built-in powerful programming functions, allowing users to customize the linkage opening method of the access control according to actual needs, and set a regular inspection plan for the access control. Through this function, the system can regularly conduct a comprehensive inspection of the access control, promptly discover and report any potential faults, thereby ensuring the continuous and reliable operation of the access control system. Fire alarm linkage: In an emergency, the host can quickly receive emergency commands from the fire automatic alarm system host, and respond immediately to open the corresponding access control. This function ensures that personnel can be quickly evacuated in emergency situations such as fires, and improves the level of safety protection. Smart fire protection networking: As an important part of the smart fire protection system, the access control host can achieve seamless docking with other fire protection equipment, becoming a key component for the linkage triggering of fire alarm information. It is usually installed in the fire control room and plays a vital role.

[0019] Detailed explanation of the internal structure: The access control host is equipped with a high-performance CPU control unit and multiple functional modules, including input IoT module, output IoT module, signal antenna, fire alarm host communication module, display output module and manual input disk. These modules perform their respective duties and together constitute a powerful functional system of the host. The input IoT module is responsible for two-way communication, which can not only receive cloud information, but also upload local information to the cloud, realizing real-time exchange and sharing of information. The manual input disk contains various operation buttons, which is convenient for users to perform manual control, improving the flexibility and convenience of operation. The output IoT module is responsible for issuing the instructions processed by the CPU to the access control controller and receiving its feedback information, ensuring the accurate transmission and execution of the instructions. The fire alarm communication module realizes real-time communication with the fire alarm host, ensuring the timely transmission and processing of fire alarm information. The display output module intuitively displays the information processed by the CPU on the screen, so that users can understand the current status of the access control system at a glance. As the core of the host, the CPU control unit receives and processes the information input by other units according to the preset logic of manual programming, and outputs relevant instructions, realizing intelligent control and management of the entire access control system. The dialogue and broadcast module is mainly responsible for realizing the broadcast and dialogue functions with the access control controller, so that the fire control room can grasp the actual situation of the fire partition from a long distance, and realize the on-site broadcast and speech functions of the fire partition in the fire control room.

[0020] Diversity of opening instructions: The access control host can accept opening instructions from multiple parties, including cloud alarm information, fire alarm system alarm information and manual triggering. Once the opening instruction is received, the host will quickly open the access control according to the preset logic. Especially in the case of failure of the fire alarm host, the remote access control host can still manually open the relevant access control wirelessly remotely, ensuring the safe evacuation of personnel in an emergency. At the same time, under economic conditions, personnel who need to be evacuated or on-site staff can also obtain alarm information through the contact number posted on the door, and then open the access control as soon as possible.

[0021] Wireless smoke sensor linkage: If wireless smoke sensors are installed in the building, when the smoke sensor of a fire partition confirms the alarm, the information will be quickly uploaded to the cloud. After receiving this information, the access control host will immediately open the corresponding access control of the fire partition. In the event of automatic trigger failure, the fire control room staff can also manually open the access control of the corresponding fire partition, and the closing process is also convenient.

[0022] Linkage with common automatic alarm host: The access control host can also be linked with common automatic alarm host. When two smoke sensors in the same fire partition alarm at the same time, the fire alarm host will send the alarm information to the access control host through various communication methods (such as network cable, bus, Internet of Things module, etc.). After receiving this information, the host will immediately send an opening signal to the control cabinet, and the control cabinet will quickly open the door, thereby ensuring the rapid evacuation of personnel in an emergency.

[0023] Fire module, fire alarm detector and fire alarm host: The fire module is responsible for transmitting the instructions of the fire alarm host to the access controller and the access control host, and feeding back the opening and closing status signal of the evacuation door to the fire alarm host. The fire alarm detector is used to detect fire information and transmit the fire information of the fire area to the fire alarm host. After receiving the alarm signal, the fire alarm host sends an opening signal to the access control host and the access controller through the fire module, and collects and displays the opening and closing status signal of the evacuation door. At the same time, the host will also send the alarm information to the sound and light alarm, issue an alarm information, and remind people to evacuate.

[0024] The user interface provides a platform for managers to interact with the access control host. Through the APP, web page (WEB operation page), fire control room host operation interface or Windows / macOS application and other user operation pages, managers can view the access control status in real time, send operation instructions, and realize remote door opening in an emergency.

[0025] When the personnel who need to be evacuated contact the access control manager through the phone number posted on the closed evacuation door, the manager can open the door in an emergency through the user interface at any time and anywhere. At the same time, when the relevant manager leaves the fire control room for some reason, he can also obtain relevant fire alarm information and operate relevant door opening instructions on his mobile phone.

[0026] In addition, after the smart firefighting instructions are uploaded to the cloud, staff can obtain relevant information about the smart firefighting on their mobile phones and computers, and manually open relevant access control systems when the linkage fails to ensure the safe evacuation of personnel.

[0027] Compared with the prior art, the beneficial effects of the present invention are specifically manifested in the following aspects: Significantly improve emergency response speed: Compared with the existing technology, this invention introduces a remote wireless opening function, so that in emergency situations such as fire, the staff in the fire control room can quickly and remotely operate the access control system, greatly shortening the opening time, thereby improving escape efficiency and reducing the risk of casualties. Enhanced system reliability: Traditional access control systems often rely on the linkage of the automatic fire alarm system, but there are problems with linkage failure or response delay. The present invention provides a dual opening mechanism (automatic and manual remote opening), which can ensure the smooth opening of the access control system even if the automatic fire alarm system fails, thus enhancing the overall reliability of the system Reduce maintenance costs and management difficulty: Traditional access control systems increase the difficulty of maintenance and management due to complex lines and long distances. This invention simplifies the system structure and reduces line maintenance costs through wireless communication technology. At the same time, the centralized control function of the access control host makes management more convenient and reduces management difficulty. Improve resource utilization efficiency: As the core of 24-hour monitoring, the fire control room's human resources are not fully utilized in the existing technology. This invention integrates the fire control room's human resources and intelligent technology to achieve remote monitoring and operation of the access control system, significantly improving resource utilization efficiency Enhanced system compatibility and scalability: This invention is not only applicable to buildings that have installed automatic fire alarm systems, but also to places that have not installed relevant systems, which enhances the compatibility of the system. At the same time, the centralized control function of the access control host makes the system easy to expand, and new access control equipment can be easily added to meet future expansion needs. Promoting the construction of smart fire protection: This invention realizes linkage with the smart fire protection system, closely combines the alarm information with the access control system, and realizes real smart management. This helps to promote the construction of smart fire protection and improve the overall fire safety level of the city. Improve user experience and satisfaction: In daily management, the present invention provides a convenient access control operation mode, which can prevent people from entering and leaving at will without locking. In an emergency, the access control can be quickly opened to ensure the safety of personnel. This access control system that meets both daily management needs and emergency situations will greatly improve the user experience and satisfaction In summary, compared with the existing technology, the present invention has significant beneficial effects in terms of emergency response speed, system reliability, maintenance cost and management difficulty, resource utilization efficiency, system compatibility and scalability, smart fire protection construction, user experience and satisfaction. These advantages make the present invention have broad application prospects and important social value in the safety management of large crowded places. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. It should be clear that the described embodiments are only a part of the present invention, not all of it. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown in the figure, a remote access control host has the ability to centrally manage access controllers and the access control doors they control in multiple buildings. Each access controller can control at least one or more evacuation doors at the same time. This figure takes two access controllers connected to five evacuation doors as an example to illustrate the workflow of the remote access control system. Importantly, these access controllers can be deployed in locations far apart, even across different cities.

[0035] When a fire occurs inside a building, if the evacuees arrive at Door 1 and find it blocked by the access control, there are two ways to open the evacuation door: The first method is to call the emergency contact number posted on Door 1, which is directly connected to the fire control room staff or the administrator of the user operation interface. After receiving the call, the staff can remotely unlock the access control through the operation button on the remote access control host or through the user operation interface (such as mobile phone APP, web page, Windows or Mac OS application) after verifying the identity of the caller and confirming the fire alarm information. This series of operations mainly relies on the wireless communication technology of the Internet of Things to realize the information transmission between various components.

[0036] The second method is to press the dedicated access control alarm button and intercom next to Door No. 1. The alarm button is equipped with a protective diaphragm and can only be pressed in an emergency. Once triggered, the alarm information will be immediately sent by the access control controller to the remote access control host through the Internet of Things module. The access control host simultaneously uploads the information to the cloud management system, and the staff can see the alarm information on the remote access control host and the user operation interface respectively. After the host receives the alarm information from Door No. 1, it will start the intercom system. After confirming the identity of the caller and the details of the fire alarm, it will send a door opening command to the access control controller through the remote access control host or the user operation interface (such as a mobile phone APP). The command is accurately transmitted to the access control controller through the connection between the front-end Internet of Things module and the Internet of Things module of the access control host, and then all the evacuation doors in the fire compartment where Door No. 1 is located are opened, such as Figure 1 The figure shows door 1 and door 2. At the same time, the opening status of door 1 and door 2 will be fed back to the access controller through the opening and closing signal switch, and then transmitted to the access control host through the above method, so that the staff in the fire control room can know the information that the door has been opened in time.

[0037] Subsequently, the fire control room staff can play preset or manual immediate evacuation instructions through the access control host. This information is transmitted to the speakers near each evacuation door through the access control controller, thereby effectively guiding people to evacuate safely and orderly through the evacuation door.

[0038] like Figure 2 The figure shows the working logic diagram of the internal components of the access control host. As a fire control device with integrated technology, the access control host has a built-in high-performance CPU control unit. As the "brain" of the entire system, it is responsible for receiving, processing and outputting information. In addition, the host is also equipped with an input IoT module and an output IoT module, which together realize two-way communication with the cloud. The input IoT module can not only receive instructions from the cloud control system, but also upload local information to the cloud. When the access controller sends information to the host, the host will upload it to the cloud through the input IoT module; similarly, any instructions issued by the user through the operation interface will first reach the cloud control system and then be transmitted back to the host through the input IoT module.

[0039] The manual input panel is an important part of the host. It contains various operation buttons, allowing users to conveniently perform manual control. The output IoT module is responsible for conveying the instructions processed by the CPU to the access controller and receiving its feedback information to ensure the accurate execution of the instructions.

[0040] The fire alarm communication module realizes real-time communication with the fire alarm host, ensuring that the access control host can respond quickly and take appropriate measures in emergency situations such as fire. The display output module intuitively displays the information processed by the CPU on the screen, allowing users to clearly understand the operating status of the system.

[0041] In addition, the dialogue and broadcast module provides a communication channel between the fire control room staff and the evacuation door intercom. After the access control alarm button is pressed, the staff can use this module to communicate with the people near the evacuation door, and after confirming the situation, notify the people in the fire partition of the evacuation information through the broadcast function.

[0042] In areas with poor antenna signals, the antenna can be connected to an open outdoor area to ensure that the access control host is not restricted by location or environment, thereby maintaining a stable communication connection.

[0043] like Figure 3 The figure shows the operation interface of the access control host. The operation interface mainly includes a display screen, operation buttons, and a broadcast and telephone operation area. The display screen can clearly display the real-time status of each access control, whether it is open or closed, it is clear at a glance. In the operation button area, for example, buttons 1-28 correspond to control access control numbers 1 to 28, so that users can control the opening and closing of each access control individually. In particular, a total button is also set in the operation button, and centralized control of multiple access control can be achieved through one-button operation, such as 1-7, 8-14, 9-21, 22-28 and other combinations, which greatly improves management efficiency. In emergency situations such as fire, all access control in the fire compartment of a building can be quickly opened to buy precious time for personnel evacuation. Even without a fire alarm host, users can rely on these buttons to send opening and closing instructions to the access control cabinet individually to achieve flexible management of access control.

[0044] The broadcast and dialogue operation area provides users with the functions of talking to the alarm person and broadcasting evacuation broadcasts. When receiving an alarm message from a dedicated alarm button or intercom, the user can quickly pick up the microphone to talk to the other party to confirm the fire situation. Once confirmed, the microphone can be used for manual broadcasting to inform the evacuees of relevant precautions; or a button can be selected to automatically broadcast the preset evacuation broadcast content to guide people to evacuate in an orderly manner.

[0045] like Figure 4 The figure shows the internal modules and external working logic of the access control controller.

[0046] The access controller mainly contains four core functional modules: antenna, IoT module, access control power supply, and dialogue and broadcast module. The antenna is designed to ensure stable signal transmission, especially when wireless signals are difficult to penetrate in some indoor places, the antenna can be extended to the open area outdoors to ensure smooth communication between the access controller and the access control host. The IoT module is responsible for receiving and sending signals. It can not only collect status information from the door opening and closing signal switch and feed it back to the access control alarm host, but also convert the digital or analog signal sent by the access control alarm host into an electrical signal, and then adjust the current on and off of the access control through the access control power supply to realize the opening and closing of the access control. As an energy source, the access control power supply provides stable power support for external broadcasting, access control magnets, intercoms, access control special alarm buttons, and evacuation door opening and closing signal switches, and accurately controls the opening and closing of the access control through the on and off of the power supply.

[0047] In terms of external working logic, the access controller has multiple functions. First, it can receive signals from the dedicated access alarm button installed near the evacuation door. In the absence of a fire alarm system or the linkage with the smart fire protection fails, personnel can press this button once they find a fire. After receiving the signal, the access controller will immediately send it to the access control host, and then upload it to the cloud. After the staff in the fire control room sees the alarm information through the monitoring platform, they can quickly open all the access control in the fire area to ensure the rapid evacuation of personnel. At the same time, managers with corresponding permissions can also remotely open the access control of the corresponding alarm place through user operation interfaces such as mobile phone APP.

[0048] In addition, the access controller can also receive information about the door opening and closing signal switch. The door signal switch monitors the door's opening and closing status in real time and sends this status to the access controller in the form of an electrical signal. The access controller transmits this information to the access control host in real time through its internal Internet of Things module, thereby achieving real-time monitoring and management of the access status.

[0049] Functions of the dialogue and broadcast module: When someone presses the dedicated alarm button for access control, the access control controller will immediately start the alarm evacuation sound to remind people to evacuate quickly, and at the same time start the intercom to realize the dialogue function between the intercom microphone of the access control host in the fire control room and the intercom microphone near the evacuation door. When the dialogue is completed and the fire is confirmed, the staff will open the access control, play the broadcast or manually broadcast the evacuation information, and realize the connection of the dialogue and broadcast functions of the fire control host.

[0050] like Figure 5As shown in the figure, Building A is equipped with an automatic fire alarm system and is connected to the fire control room. When a fire occurs, the fire alarm detector (including the on-site manual alarm device) can quickly identify the fire and send an alarm signal to the fire alarm host. The fire alarm host then activates the sound and light alarm, issues an evacuation order, and simultaneously sends an order to open the door to the access control host and the fire module. After receiving the order, the fire module converts the digital signal into an electrical signal and transmits it to the building's access controller. Once the access controller receives this signal, it will immediately power on and open the door. At the same time, the access control host maintains real-time communication with the access controller through its built-in Internet of Things module. As long as the access controller receives any (or simultaneous) opening signal from the fire module or the access control host, it will immediately execute the door opening operation. After the door is opened, the access controller will receive the feedback signal of the evacuation door opening and closing signal switch and send it to the fire alarm host and the access control host. During the entire signal transmission process, the fire module and the fire alarm host and access controller use cables for transmission, while the access controller and the access control host use wireless communication. This wireless control function provides a powerful supplement to the wired transmission of the fire module, and can effectively deal with problems such as poor line, signal attenuation, cable aging, transmission failure and module failure, ensuring that the access control can be opened quickly and smoothly in an emergency.

[0051] The above opening method is automatic opening. However, when the on-duty personnel leave or the device is set to non-automatic mode, the automatic opening function will fail, and the access control needs to be opened manually. After the building detector detects the alarm information and transmits it to the fire alarm host, the fire alarm host will communicate with the access control host, and the access control host will upload the command to open the access control to the cloud through the Internet of Things module. Staff can view the information of fire equipment in real time and send instructions through user interface devices such as mobile phones. At the same time, they can also receive fire alarm information pushed by the access control host through mobile phone APP and other methods.

[0052] If the linkage start method fails, or the fire alarm host does not receive feedback information about the access control opening, or there is a fault in the building fire alarm system that causes the corresponding fire partition access control to fail to open completely, the staff can use the user interface device management account to perform a one-click operation to remotely open the access control of the corresponding fire partition of the building. The IoT module will wirelessly transmit the opening signal to the access control controller, and then the access control of the corresponding fire partition of the building will be opened. The remote access control host will simultaneously receive feedback information about the opening of the corresponding fire partition access control.

[0053] After the fire is over, the fire control room staff can close the access control in the following ways: close the corresponding fire partition access control with one-click operation on the access control host; close the corresponding fire partition access control through the user interface device management account operation; close the corresponding fire partition access control one by one at the access control controller site; or manually close the access control on the fire control host control panel. The Internet of Things module will wirelessly transmit the closing signal to the access control controller, and then the access control will be closed. The access control host will receive feedback information on the closure of the access control of the corresponding fire partition of the building, and synchronously feedback it to the fire alarm host. At the same time, the access control controller will also feedback the closing signal to the fire alarm host through the fire module. Subsequently, the access control will return to the normal working mode, that is, the state where the evacuation door access control is powered on and closed.

[0054] It should be noted that the embodiments described above are only used to help explain the working principle and practical application of the present invention, and do not describe all the details in detail, nor limit the specific implementation methods of the present invention. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and use the present invention.
