Description

Technical Field

[0001] This utility model relates to the field of fire alarm control panel technology, specifically to a remote control device and system for a fire alarm control panel. Background Technology

[0002] In the current fire monitoring and emergency response system, the fire alarm control panel, as the core control unit, undertakes key tasks such as receiving signals from fire detectors, executing linkage control logic, and driving the activation of fire extinguishing equipment. However, with the expansion of urban building scale and the increase in the complexity of fire protection systems, traditional fire alarm control panels have gradually revealed significant shortcomings in remote management, status visualization, and emergency control. Although some systems have attempted to introduce user information transmission devices or graphical remote monitoring platforms to achieve remote uploading and visualization of alarm information, these solutions generally suffer from problems such as functional fragmentation, strong protocol dependence, and insufficient control depth, making it difficult to meet the practical needs of modern fire protection for "early detection, early control, and early response."

[0003] Specifically, in existing technologies, some scholars have proposed remote control methods based on user information transmission devices. This approach achieves data interaction between the host and the platform through protocol parsing. However, its control commands are limited by the host's native protocol, failing to cover all brands and models, and lacks direct intervention capabilities regarding the host's manual / automatic status. In other words, this method cannot intuitively view the host's status and relies on parsing the host's uploaded information. Furthermore, while existing remote monitoring systems integrate graphic displays, video surveillance, and alarm hosts into a single industrial control computer, achieving visualized monitoring and remote operation, their dispersed deployment of multiple devices and redundant structure not only increase installation and maintenance costs but also fail to address the industry pain point that some hosts cannot remotely trigger critical functions (such as manual / automatic mode switching) due to protocol closures. More importantly, GB 25506-2010 "General Technical Requirements for Fire Control Rooms" clearly stipulates that fire alarm systems should be in automatic mode. However, in actual operation and maintenance, in order to avoid false alarms and malfunctions, many projects have kept the main unit in manual mode for a long time, and then manually switched it after confirming a real fire alarm. This "last mile" bottleneck seriously delays the efficiency of emergency response, and existing technologies have failed to provide a systematic solution that takes into account compatibility, integration and deep control capabilities.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] This utility model provides a remote control device and system for a fire alarm control panel, which can at least partially improve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A remote control device for a fire alarm control panel includes: a fire alarm control panel data acquisition and control device, an image acquisition module, and a manual / automatic switching module. The data terminal of the fire alarm control panel data acquisition and control device is used for communication with a fire alarm control panel. The data terminal of the fire alarm control panel data acquisition and control device is electrically connected to the data terminal of the image acquisition module. The data terminal of the fire alarm control panel data acquisition and control device is used for communication with a remote server. The output terminal of the fire alarm control panel data acquisition and control device is electrically connected to the control terminal of the manual / automatic switching module. The output terminal of the manual / automatic switching module is used to control the manual / automatic key of the fire alarm control panel. The image acquisition module is configured to acquire panel images of the fire alarm host, the fire alarm host acquisition and control device is configured to acquire the operating information of the fire alarm host and report it to the remote server, as well as receive and decrypt encrypted instructions sent by the remote server and send instructions to the fire alarm host, and the manual / automatic switching module is configured to switch the state of the fire alarm host from active state to manual state or switch the state of the fire alarm host from manual state to active state.

[0008] This utility model also provides a remote control system for fire alarm control panels, which includes: multiple fire alarm control panels, a server, and a remote control device for fire alarm control panels as described above. The data terminal of the fire alarm control panel is communicatively connected to the fire alarm control panels and the server for data interaction.

[0009] In summary, the fire alarm control panel remote control device and system proposes an integrated solution combining "protocol simulation + mechanical execution" for the scenario of "remote control of the fire alarm control panel." Centered on a highly integrated acquisition and control device, it utilizes the address rules of the original manufacturer's proprietary master-slave protocol to disguise itself as a "superior host," directly issuing reset, silencing, and equipment start / stop commands to the fire alarm control panel via RS-232 / RS-485 / CAN bus, achieving deep control without requiring protocol openness. For manual / automatic mode switching that cannot be completed via data frames, the device utilizes a built-in magnetic clamping arm + rotary motor + position feedback micro-actuator to remotely turn the key switch, completing the physical state switch and sending back a confirmation signal. The device also provides encrypted Ethernet / 4G dual-channel cloud connection and reserves a network port for camera access, transmitting panel images in real time to achieve a closed loop of "status visibility + command controllability." The cloud platform is responsible for encrypted command issuance and data aggregation, allowing users to view host information, video footage, and remotely control the device with a single click through the terminal. This solution is compatible with multiple brands of hosts without altering the existing cabling or disrupting the original system hierarchy. It solves three major pain points that have long plagued maintenance personnel: "closed protocols, inability to remotely adjust manual or automatic modes, and lack of visibility of status." It significantly reduces the response time from fire confirmation to coordinated execution, and improves the reliability, compliance, and deployment efficiency of remote fire management.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0012] refer to Figure 1 As shown, the first embodiment of this utility model discloses a remote control device for a fire alarm control panel, which includes: a fire alarm control panel data acquisition and control device, an image acquisition module, and a manual / automatic switching module. The data terminal of the fire alarm control panel data acquisition and control device is used for communication with a fire alarm control panel. The data terminal of the fire alarm control panel data acquisition and control device is electrically connected to the data terminal of the image acquisition module. The data terminal of the fire alarm control panel data acquisition and control device is used for communication with a remote server. The output terminal of the fire alarm control panel data acquisition and control device is electrically connected to the control terminal of the manual / automatic switching module. The output terminal of the manual / automatic switching module is used to control the manual / automatic key of the fire alarm control panel. The image acquisition module is configured to acquire panel images of the fire alarm host, the fire alarm host acquisition and control device is configured to acquire the operating information of the fire alarm host and report it to the remote server, as well as receive and decrypt encrypted instructions sent by the remote server and send instructions to the fire alarm host, and the manual / automatic switching module is configured to switch the state of the fire alarm host from automatic to manual or switch the state of the fire alarm host from manual to automatic.

[0013] Preferably, the image acquisition module is a camera module.

[0014] Preferably, the communication methods between the fire control panel and the fire alarm control panel include RS232, RS485, and CAN.

[0015] Preferably, the communication method between the fire control panel and the remote server includes 4G or Ethernet.

[0016] Preferably, the control protocol between the fire alarm control panel and the fire alarm host is a master-slave relationship simulation control, wherein the fire alarm control panel simulates the master and the controlled fire alarm host is configured as the slave, so that the fire alarm control panel simulates the master protocol to control the simulated slave fire alarm host.

[0017] Specifically, in this embodiment, the fire alarm control panel connects to the fire alarm host via RS232, RS485, CAN, or other methods. Simply put, the fire alarm control panel collects operational information from the fire alarm host. For example, if a smoke detector in a sub-device of the fire alarm host triggers an alarm, the control panel obtains the alarm information from the alarm host through its RS232 or RS485 interfaces and uploads it to the platform. This allows the platform to remotely monitor the fire alarm host's status. Furthermore, remote control commands from the alarm host are encrypted and sent via the cloud platform. The fire alarm control panel decrypts these commands before sending them to the fire alarm host. In other words, the fire alarm control panel can also control actions such as resetting, silencing, starting and stopping bus devices, and starting and stopping multi-line devices via the cloud platform. It should be noted that the difference between the fire alarm control panel and existing systems is that the fire alarm control panel highly integrates routing, 4G, data acquisition, and control modules, unlike existing solutions where multiple modules are separate.

[0018] Furthermore, when remote control is required, the original fire alarm control panel can only be operated locally via buttons to activate related devices, such as audible and visual alarms, smoke exhaust fans, and fire hydrant pumps in the event of a fire. The remote control device for the fire alarm control panel, however, can connect remotely through the master-slave network interface of the original fire alarm control panel, and then issue relevant commands from the cloud platform to operate the fire alarm control panel and its sub-devices. Specifically, the server sends encrypted commands to the acquisition and control device, which decrypts them and sends reset, silencing, and start / stop commands to the alarm control panel according to the original master-slave protocol format. The alarm control panel identifies the source address as "master," executes the corresponding action, and returns confirmation, completing the protocol-level remote control. It should be noted that traditional fire alarm control panels can establish local master-slave networks, allowing the master to control the slave devices. The control commands in this device are also issued through a simulated master mechanism.

[0019] The camera can access the network provided by the fire alarm control panel and transmit important information from the panel to the platform. Specifically, the camera module is connected to the control panel via Ethernet, capturing and uploading images of the control panel in real time for remote verification of button presses, light status, and switching results, forming a visual closed loop. Thus, the device uses "protocol simulation" to complete common controls, "mechanical rotation" to fill protocol blind spots, and "image confirmation" to ensure reliable operation, achieving true remote management of the fire alarm control panel without altering the original wiring or disclosing proprietary protocols.

[0020] Please see Figure 2Preferably, the manual / automatic switching module adopts a mechanical clamping arm device, which includes a magnetic clamping arm, a cross-slot clamping head, a rotary motor, and a positioning detection module. The control end of the rotary motor is electrically connected to the output end of the fire alarm control panel. The magnetic clamping arm is installed on the fire alarm control panel and is telescopic. The magnet on the clamping arm is used for auxiliary fixation. The cross-slot clamping head is configured on the magnetic clamping arm and engages with the manual / automatic key of the fire alarm control panel. The output end of the rotary motor is connected to the magnetic clamping arm to drive the cross-slot clamping head and the manual / automatic key of the fire alarm control panel to rotate together. The positioning detection module is used to detect whether the manual / automatic key has rotated to the correct position.

[0021] GB 25506-2010 "General Technical Requirements for Fire Control Rooms" Clause 4.2.1c states: "Fire alarm systems, fire extinguishing systems, and other linkage control equipment should be kept in normal working condition. Equipment that should be in automatic mode should not be set to manual mode." In actual operation and maintenance, many projects keep fire alarm activation in manual mode for extended periods to prevent false alarms and accidental activation. The manual switch is only switched to automatic mode upon confirmation of a real fire. At this point, the fire control panel will execute the built-in linkage procedures, such as starting the fire pump, closing fire doors, and activating smoke exhaust fans. Therefore, manual-to-automatic switching is a crucial function in remote fire control systems.

[0022] Specifically, in this embodiment, due to the large number of brands of fire alarm control panels, the manual and automatic modes of some fire alarm control panels cannot be switched via protocol. Therefore, this device involves a mechanical clamping arm structure (this structure is installed on the fire alarm control panel via a telescopic clamping arm, with magnets on the clamping arm for auxiliary fixation). This auxiliary mechanical structure allows for the rotation of the manual / automatic key, remotely controlling the key's rotation and achieving manual / automatic mode switching. For manual / automatic keys that cannot be controlled via data frames, the manual / automatic switching module is magnetically attached to the metal frame of the control panel, with the module's output shaft aligned with the key (i.e., the fire alarm control panel's manual / automatic key can be inserted through the cross slot on the actuator). The fire alarm control panel's control settings have adjustment buttons to control the key's rotation angle. By controlling a micro motor to drive the cross slot head to rotate forward or backward, the key rotates. Once in position, the module provides a feedback signal, and the device stops outputting, achieving a physical switch between manual and automatic modes. Throughout the process, the module and panel are not rigidly connected, thus not damaging the original structure and adaptable to various types of fire alarm control panels' manual / automatic switching keys. Furthermore, this actuator has a position switch to detect whether the key selection control has been executed correctly. This manual / automatic switching device effectively solves the problem of remote manual / automatic switching of the fire alarm control panel. The magnetic clamp installation does not alter the structure and is of great significance for maintaining the consistency of the fire alarm control panel.

[0023] In summary, the fire alarm control panel communication device communicates with the server via 4G or Ethernet, enabling it to collect information from and control the fire alarm control panel. In addition to software control, it includes a mechanical structure for manual / automatic control of the fire alarm control panel, and provides a network interface for the control panel's monitoring camera to connect. Specifically, the fire alarm control panel remote control device is designed to address three key pain points for fire safety personnel: enabling the fire alarm control panel to understand remote commands, see the actual status of the panel, and operate the mechanical key. It connects in parallel via any maintenance port of RS-232 / RS-485 / CAN, requiring no modification to the original circuit and operating immediately upon power-up. The internal control module sets its own source address as the host, periodically querying the alarm control panel. The host, acting as a slave, transmits encrypted operating data via 4G or Ethernet. On-duty personnel can view fire alarms, faults, shielding, and manual / automatic status indicators in real time on the terminal, solving the problem of "invisible status." When remote control is required, reset, mute, start / stop commands issued by the platform are also sent in master-slave protocol frame format. The host recognizes the commands, executes them immediately, and returns confirmation, achieving "zero wiring and deep control." Addressing the issue of some main unit manual / automatic keys being detached from the bus, the manual / automatic switching module on the side wall of the device uses a magnetic base to attach to the panel. A micro motor drives the key to rotate, and the switch stops upon receiving a feedback signal, completing the physical switch. This process neither damages the lock cylinder nor affects the original structure, truly implementing the GB 25506-2010 clause that "the key must not be left in manual mode for extended periods." A synchronously operating camera module transmits the panel image back in real time. The platform verifies the command results using the image, forming a "visual-execution-confirmation" closed loop, eliminating misoperation and omissions. Therefore, this utility model replaces the traditional "multi-device distributed" solution with a single "box," is compatible with multiple brands of main units, requires only fifteen minutes to install, significantly reduces construction and maintenance costs, and shortens the response time from fire confirmation to coordinated execution. It provides a simple, safe, and compliant remote fire management upgrade path for existing buildings and new projects.

[0024] Compared with existing technologies, the aforementioned fire alarm control panel remote control device has the following advantages: 1. High integration, incorporating multiple functions, facilitating deployment and implementation. 2. The device control commands simulate master-slave communication within the fire alarm control panel system, without damaging the original system. 3. The addition of a mechanical control structure addresses the issue of some functions being uncontrollable by the main unit via commands.

[0025] The second embodiment of this utility model provides a remote control system for a fire alarm control panel, which includes multiple fire alarm control panels, a server, and a remote control device for the fire alarm control panel as described above. The data terminal of the fire alarm control panel is communicatively connected to the fire alarm control panels and the server for data interaction.

[0026] Preferably, the server communicates and interacts with mobile terminals and PCs via a cloud platform.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
