Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a flowchart of an embodiment of the Internet of Things-based remote control method for fire-fighting equipment according to the present invention. Detailed Implementation

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, specific embodiments and accompanying drawings will be used to clearly and completely describe the technical solution protected by this application. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this patent.

[0022] This application provides a method, system, device, and medium for remote control of fire-fighting equipment based on the Internet of Things, solving the urgent technical problem of remotely controlling fire-fighting equipment.

[0023] A method for remote control of fire-fighting equipment based on the Internet of Things, the method comprising: Step S1: The user information transmission device acquires the fire scene data collected by the fire detector; Step S2: Establish an encrypted communication connection between the user information transmission device and the fire remote monitoring center; Step S3: The fire remote monitoring center acquires fire scene data through the user information transmission device, displays the acquired fire scene data on the display screen, and sends control commands to the user information transmission device; The user information transmission device is responsible for transmitting information and control commands between the fire scene and the remote fire monitoring center to ensure that fire equipment can be operated remotely safely and efficiently.

[0024] Fire alarm control panel and fire detectors are installed at various locations where fire protection is required. Fire detectors are used to detect smoke concentration and ambient temperature, while fire alarm control panel is used to control the start and stop of fire fans, the opening and closing of fire pump valves, the opening and closing of zoned roller shutters, and the opening and closing of floor vents. User information transmission devices are typically installed in the on-site fire control room to acquire smoke concentration and ambient temperature detected by fire detectors. Based on this information, they control the start / stop of fans and the opening / closing of valves in the fire alarm control system. Through an encrypted network connection, they communicate bidirectionally with the remote fire monitoring center, sending data and receiving commands. These user information transmission devices serve as the information bridge for the Internet of Things (IoT) fire protection system, enabling remote personnel to view and control fire equipment in real time.

[0025] The user information transmission device establishes an encrypted connection with the fire remote monitoring center using a wired network, mobile network (2G / 4G / 5G), or Wi-Fi. The communication protocol employs secure formats such as TCP / UDP, HTTPS POST+JSON, or MQTT+SSL+JSON to ensure data transmission is not intercepted by hackers. In other words, instructions issued by the fire remote monitoring center are sent and received in encrypted form to prevent unauthorized access.

[0026] When the fire remote monitoring center issues control commands, the user information transmission device is responsible for verifying authorization. Using the AK-SK authentication mechanism, it verifies the command signature to ensure the command originates from a legitimate source. Commands that fail verification are rejected, protecting system security. Afterward, the transmission device converts the authorized command into a protocol command that the device can understand (232 serial port protocol, 485 serial port protocol, CAN protocol, TCP / UDP protocol, or other custom protocols) and sends it to the fire linkage controller for execution. The user information transmission device monitors the execution results of the fire equipment in real time (whether the fan has started successfully) and feeds back the status to the fire remote monitoring center. This ensures fast and accurate fire operation.

[0027] The user information transmission device supports periodic automatic inspection, records temperature curves, and pushes alarms to the terminal when the temperature rises too quickly.

[0028] The user information transmission device is the core of the Internet of Things (IoT) fire protection system. Through encryption and authentication, it prevents malicious control. Firefighters can automatically start fire pumps and adjust fans through the fire remote monitoring center without going to the site. It can also automatically detect existing fire hazards, send alarms in a timely manner, and prevent the fire from spreading.

[0029] Step S5: The user information transmission device verifies the authorization status of the control command, decrypts the command content and verifies the authorization using the AK-SK authentication mechanism, converts the authorized control command into a device protocol command, and sends it to the corresponding fire linkage controller. By verifying the authorization status of control commands through a user information transmission device and using the AK-SK authentication mechanism to decrypt and verify permissions, the problem of lack of security authentication in command transmission in existing technologies is solved, effectively preventing unauthorized operations and ensuring the legality and security of fire control commands.

[0030] By automatically converting authorized control commands into device protocol commands and sending them to the fire alarm control panel, the problem of incompatibility between remote commands and on-site device protocols is solved, achieving seamless integration of control commands with various types of fire alarm equipment and avoiding response delays caused by manual protocol conversion.

[0031] Step S6: The user information transmission device monitors the execution result of the fire linkage controller and feeds back the execution result to the fire remote monitoring center in real time.

[0032] The fire remote monitoring center uses Internet of Things (IoT) technology to monitor the smoke concentration and ambient temperature at the fire scene in real time. Based on the smoke concentration and ambient temperature, it can remotely control the start and stop of fire fans, the opening and closing of fire pump valves, the opening and closing of zoned roller shutters, and the opening and closing of floor air vents in emergencies.

[0033] The fire remote monitoring center collects smoke concentration and ambient temperature data from the fire linkage controllers at each fire scene through a user information transmission device. All information is transmitted in encrypted form (such as HTTPS or MQTT+SSL) to prevent hacking.

[0034] The fire remote monitoring center is equipped with a display screen, which shows the smoke concentration and ambient temperature collected by the fire linkage controllers at each fire scene from the user information transmission device. The display screen shows the detected ambient temperature and smoke concentration. Based on the ambient temperature and smoke concentration, the fire remote monitoring center remotely controls the fire linkage controller at the corresponding fire site. It issues commands through AK-SK certification to control the start of fire fans, the opening and closing of fire pump valves, the opening and closing of zoned roller shutters, and the opening and closing of floor air vents. Only commands that have passed AK-SK certification will be executed.

[0035] The fire remote monitoring center can also analyze the ambient temperature curve in real time and display the temperature curve on the screen. If the temperature rise rate exceeds the threshold, a fire early warning signal is immediately generated, the fire linkage controller is controlled to take action, and the alarm flashes on the screen.

[0036] Based on the above embodiments, in order to further improve the IoT-based remote control method for fire equipment provided in the above embodiments, and to provide an implementable approach, in one embodiment, the encrypted communication connection adopts at least one of the following communication methods: Wired network, 2G / 4G / 5G mobile network or WIFI; The communication protocol uses TCP / UDP, HTTPS POST+JSON, or MQTT+SSL+JSON format for encrypted data transmission.

[0037] In one exemplary embodiment, the verification control instruction authorization includes: Provide the Access Key ID and Secret Access Key to the fire remote monitoring center; Verify the match between the signature carried by the control command and the encryption algorithm; Requests to execute instructions that have not passed AK-SK certification will be rejected.

[0038] According to another embodiment of the present invention, the conversion device protocol instructions include: It comes pre-installed with multiple communication protocol templates, including RS-232 serial port protocol, RS-485 serial port protocol, CAN bus protocol, and TCP / UDP protocol; Match the corresponding communication protocol template based on the host protocol identifier in the control command.

[0039] It should be further explained that both the fire alarm control panel and the fire detectors are installed at various locations where fire protection is required. The fire detectors are used to detect smoke concentration and ambient temperature, while the fire alarm control panel is used to control the start and stop of the fire fans, the opening and closing of the valves of the fire pumps, the opening and closing of the zoned roller shutters, and the opening and closing of the floor vents.

[0040] Furthermore, as a refinement and extension of the specific implementation methods of the above embodiments, in order to fully illustrate the specific implementation process of this embodiment, another remote control method for fire-fighting equipment based on the Internet of Things is provided, the method further including: The detected ambient temperature is used to generate temperature curve data; When the rate of temperature rise exceeds the threshold, a fire warning signal is generated, the fire alarm control panel is activated, and the alarm flashes on the display screen.
