Description

Technical Field

[0001] This invention relates to the field of fire monitoring technology, and in particular to a fire remote control system and method. Background Technology

[0002] With the acceleration of urbanization and the increase in building volume, the importance of fire safety management is becoming increasingly prominent. As the core of building fire protection, automatic fire alarm systems undertake the critical tasks of fire monitoring, alarm, and linkage control. Traditional fire alarm systems typically use a fire alarm controller as the core, connecting various detectors and actuators to form a localized monitoring network.

[0003] However, existing fire management practices present the following key technical challenges: First, the fire equipment market is saturated with numerous brands, and fire alarm controllers from different manufacturers typically employ proprietary, closed underlying communication protocols. This makes it difficult for devices from different brands to interconnect, creating data silos. For managers with multiple dispersed projects (such as chain enterprises or property groups), it is difficult to achieve centralized monitoring and remote control across regions and manufacturers through a unified platform, increasing operation and maintenance costs and management complexity.

[0004] Therefore, there is a need for a fire remote control system and method that can solve the problems of decentralized fire equipment management, difficulty in remote control, and incompatibility of heterogeneous equipment protocols in the existing technology. Summary of the Invention

[0005] One of the objectives of this invention is to provide a fire protection remote control system that can solve the problems of decentralized fire protection equipment management, difficulty in remote control, and incompatibility of heterogeneous equipment protocols in the prior art.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: A fire protection remote control system includes a fire alarm controller and data acquisition equipment installed in a fire control room, and also includes a fire protection cloud platform in the cloud. The fire alarm controller is used to receive signals from the fire protection equipment at the bottom floor and to perform logical judgment and linkage control. The data acquisition equipment is used to acquire data frames sent by the fire alarm controller during the data uplink process and to verify the received data frames; The data acquisition equipment is also used to parse data frames according to preset protocols in the communication protocol library, convert them into standardized format data, and upload them to the fire protection cloud platform; The fire protection cloud platform is used to receive data, store and analyze the data, and update the operating status of fire protection equipment in real time on a visual interface.

[0007] Furthermore, during the data downlink process, the fire cloud platform is used to provide a human-machine interface to receive control requests initiated by users for specific fire equipment or fire alarm controllers. The fire protection cloud platform is used to generate corresponding general control commands based on control requests and send them to data acquisition devices; After receiving a general control command, the data acquisition device converts the general control command into a specific private protocol command that the fire alarm controller can recognize, based on the device type and command configuration table stored internally, and then sends it to the fire alarm controller.

[0008] Furthermore, the fire-fighting equipment includes one or more of the following: smoke detectors, heat detectors, manual alarm buttons, audible and visual alarms, smoke exhaust fans, and fire pumps.

[0009] Furthermore, the data acquisition device is physically connected to the fire alarm controller via a serial port, and accesses the Internet via a wireless or wired network, thereby establishing a communication connection with the fire protection cloud platform.

[0010] Furthermore, the fire protection cloud platform is used to generate corresponding general control commands based on the control request and send them to the data acquisition equipment after the user enters the correct control password to verify their identity.

[0011] Furthermore, when the data acquisition device parses the data frame, it identifies the starting character and command word of the frame header and extracts key information from the data segment, including functional attributes, information type, device status, loop number, address number, and device type. After parsing, the data acquisition device converts the heterogeneous hexadecimal protocol data into JSON format data that the fire cloud platform can recognize, and encapsulates the reporting time and device source address information before uploading it to the fire cloud platform.

[0012] Furthermore, it also includes image acquisition equipment, installed in the fire control room, for acquiring surveillance video from the fire control room; The data acquisition equipment is also used to acquire surveillance video from image acquisition equipment and upload it to the fire protection cloud platform; The fire protection cloud platform is also used to receive surveillance videos, use image recognition algorithms to identify the personnel on duty in the fire control room, and calculate the number of personnel on duty. The fire protection cloud platform is also used to generate abnormal alarm information for on-duty personnel when it detects that there are no on-duty personnel in the fire control room or that the number of on-duty personnel is lower than the preset personnel threshold.

[0013] Furthermore, the fire protection cloud platform is also used to record the duration of the absence of personnel when it is detected that there are no personnel on duty in the fire control room; Upon receiving a fire alarm signal, the fire cloud platform also determines whether there are personnel on duty in the fire control room. If there are personnel on duty in the fire control room and no control operation is detected through the fire alarm controller within the first preset time, the fire cloud platform generates a remote control reminder. If there are no personnel on duty in the fire control room, the fire cloud platform is also used to immediately generate remote control reminders and display the duration of the absence of personnel on duty on the human-machine interface. At the same time, it can receive control requests for specific fire equipment or fire alarm controllers through the human-machine interface.

[0014] Furthermore, the fire protection cloud platform is also used to determine a conflict resolution strategy based on the head orientation and movement trajectory of the identified personnel if the monitoring video detects the return of on-duty personnel after receiving a control request. If the fire cloud platform detects that the operator's head is facing the signal indicating that they are first observing the fire equipment, and then inputs a local control command through the fire alarm controller, it will determine whether the local control command conflicts with the remote control command to be issued by the fire cloud platform; if there is a conflict, the fire cloud platform will generate an early warning message through the human-machine interface. If the fire protection cloud platform detects that the movement trajectory of the on-duty personnel shows that they are heading directly to the fire alarm controller, and the recorded duration of the on-duty personnel leaving is less than the second threshold, then it obtains the local control command input through the fire alarm controller and determines whether the local control command conflicts with the remote control command; if there is a conflict, the fire protection cloud platform displays the local control command on the human-machine interface.

[0015] The second objective of this invention is to provide a remote fire control method using the aforementioned system.

[0016] This solution pre-installs a communication protocol library in the data acquisition device and adopts a mechanism for protocol parsing and standardized conversion. It can parse and convert heterogeneous private protocol data from different manufacturers into a standardized format that is universal to the cloud platform. At the same time, it translates the general control commands in the cloud into private commands for specific devices, breaking down the communication barriers between fire protection equipment of different brands. This allows users to achieve unified monitoring and remote reverse control of fire protection equipment of different brands and locations on the same platform without worrying about the differences in the underlying hardware. Attached Figure Description

[0017] Figure 1 This is a logic block diagram of a first embodiment of a fire remote control system. Detailed Implementation

[0018] The following detailed description illustrates the specific implementation method: Example 1 like Figure 1As shown in this embodiment, a fire remote control system includes fire-fighting equipment, a fire alarm controller, data acquisition equipment, and a fire cloud platform. In other embodiments, the fire alarm controller may also be a fire linkage controller.

[0019] The fire protection equipment specifically includes field equipment such as smoke detectors, heat detectors, manual alarm buttons, audible and visual alarms, smoke exhaust fans, and fire pumps. These devices are connected to the fire alarm controller via bus, multi-line direct control panel, or wireless means.

[0020] As the main equipment on site, the fire alarm controller is responsible for receiving signals from the underlying fire protection equipment and performing logical judgments and linkage control.

[0021] As a hub connecting the on-site fire protection network and the cloud, the data acquisition equipment is physically connected to the fire alarm controller on one end via a serial port (such as RS232 or RS485), and accesses the Internet via a wireless network (such as 4G / 5G / NB-IoT) or a wired network on the other end, thereby establishing a communication connection with the fire protection cloud platform. For example, a long connection can be established through the MQTT protocol to achieve real-time bidirectional data transmission.

[0022] The data acquisition equipment has a built-in communication protocol library with preset protocols for different brands of fire alarm controllers.

[0023] The data acquisition equipment is used during the data uplink process, specifically the acquisition and uploading phase of status information, to acquire data frames sent by the fire alarm controller via the serial port and to verify the received data frames. For example, it uses the CRC16 checksum algorithm to calculate the checksum of the received data and compares it with the checksum at the end of the frame. If the verification passes, the data is confirmed to be valid.

[0024] The data acquisition device is also used to parse data frames according to preset protocols in the communication protocol library. Taking the parsing of a manufacturer's hexadecimal serial communication protocol as an example, the data acquisition device identifies the start character (such as 0xF0) and command word (such as 0xA5 indicating a send event) in the frame header, and then extracts key information such as functional attributes (such as 0xC3 indicating a fire alarm), information type (such as 0x01 indicating a probe), device status, loop number, address number, and device type from the data segment.

[0025] After parsing, the data acquisition device converts the heterogeneous hexadecimal protocol data into standardized format data (such as JSON format) that the fire cloud platform can recognize, and encapsulates information such as reporting time and device source address, and uploads it to the fire cloud platform via the network.

[0026] The fire protection cloud platform receives data, stores and analyzes it, and updates the operating status of fire protection equipment in real time on a visual interface, such as normal, fire alarm, fault, start-up, and feedback, thereby enabling remote monitoring of on-site fire protection facilities.

[0027] During the data downlink process, i.e., the issuance and execution phase of remote control commands, the fire protection cloud platform provides a human-machine interface to receive control requests initiated by users for specific fire protection equipment or fire alarm controllers. In this embodiment, control requests include two categories: host control and component control. Host control includes global commands for the fire alarm controller, such as reset, silencing, and self-test. Component control involves starting or stopping specific fire protection equipment such as smoke exhaust fans and water pumps.

[0028] The fire protection cloud platform is used to generate corresponding general control commands based on the control request and send them to the data acquisition equipment after the user enters the correct control password to verify their identity.

[0029] After receiving general control commands from the cloud, the data acquisition device converts the general control commands into specific private protocol commands that the fire alarm controller can recognize, based on the device type and command configuration table stored internally, and then sends them to the fire alarm controller.

[0030] Specifically, the data acquisition device calls the corresponding protocol driver based on the brand and model of the currently connected fire alarm controller. For example, if it is necessary to control the XX brand fire alarm controller to perform a reset operation, the data acquisition device assembles a data frame that conforms to the brand's protocol. For example, it constructs a hexadecimal instruction sequence containing the start character 0xF0, the target address 0x00, the data length 0x01, the command word 0xA1 (reset), and the calculated CRC16 check value, and sends it to the fire alarm controller via the serial port.

[0031] For component control, such as starting a smoke exhaust fan at a specific address, the data acquisition device generates a control message containing specific address information based on the component's loop number, address number, and the corresponding start command word (e.g., 0xC1 or other manufacturer-defined function codes). Upon receiving this serial port command, the fire alarm controller parses the control intent and drives the corresponding fire-fighting equipment to perform actions (e.g., fan start) via fieldbus or direct control lines. Feedback signals from the fire-fighting equipment actions (e.g., fan operation feedback) are then fed back to the data acquisition device via the fire alarm controller and uploaded to the fire protection cloud platform, thus forming a closed-loop remote control process.

[0032] This embodiment also provides a fire remote control method using the above-described system.

[0033] This solution pre-installs communication protocol libraries for various brands of fire alarm controllers in the data acquisition equipment and employs a protocol parsing and standardization conversion mechanism. This enables the parsing and conversion of heterogeneous proprietary protocol data from different manufacturers into a standardized format common to the cloud platform. Simultaneously, it translates general control commands from the cloud into proprietary commands for specific devices, breaking down communication barriers between different brands of fire protection equipment. This allows users to achieve unified monitoring and remote reverse control of fire protection equipment from different regions and brands on the same platform without needing to worry about differences in the underlying hardware.

[0034] This solution not only supports the reporting of status information but also enables the precise issuance and execution feedback of remote control commands. Through serial port connections between the data acquisition device and the fire alarm controller, as well as a long-term MQTT connection to the cloud, the system can verify data validity in real time. After issuing control commands, it uploads feedback signals from the acquired devices to the PTZ (pan-tilt unit), significantly improving the reliability and real-time performance of remote control and ensuring the effective implementation of remote operations.

[0035] Example 2 The difference between this embodiment and Embodiment 1 is that the system described in this embodiment also includes an image acquisition device, installed in the fire control room, for acquiring monitoring video from the fire control room. In this embodiment, the image acquisition device is a surveillance camera. Correspondingly, the data acquisition device is also configured to acquire monitoring video from the image acquisition device and upload it to the fire protection cloud platform.

[0036] The fire protection cloud platform also receives surveillance video and uses image recognition algorithms to identify personnel on duty in the fire control room and calculate their number. It also generates an alarm for abnormal personnel when no personnel are detected in the fire control room, or when the number of personnel falls below a preset threshold. Furthermore, the platform records the duration of personnel absence when no personnel are detected in the fire control room.

[0037] When the system receives a fire alarm signal, the fire protection cloud platform determines whether there are personnel on duty in the fire control room. If there are personnel on duty in the fire control room, and no control operation is detected through the fire alarm controller within a first preset time (e.g., 15 seconds), the fire protection cloud platform generates a remote control reminder.

[0038] If there are no personnel on duty in the fire control room, the fire cloud platform will immediately generate a remote control reminder and display the duration of the absence of the personnel on duty on the human-machine interface. At the same time, it will receive control requests for specific fire equipment or fire alarm controllers through the human-machine interface.

[0039] The fire protection cloud platform is also used to determine conflict resolution strategies based on the head orientation and movement trajectory of personnel identified during monitoring video when a control request is received. If the fire cloud platform detects that the operator's head is facing the signal indicating that they are first observing the fire equipment, and then inputs a local control command through the fire alarm controller, it will determine whether the local control command conflicts with the remote control command to be issued by the fire cloud platform. If there is a conflict, the fire cloud platform will generate an early warning message through the human-machine interface to prevent mis-input due to the operator's haste upon returning to duty.

[0040] If the fire protection cloud platform detects that the movement trajectory of the on-duty personnel shows that they are heading directly towards the fire alarm controller, and the duration of the recorded departure of the on-duty personnel is less than the second threshold (e.g., 30 seconds), then it obtains the local control command input through the fire alarm controller and determines whether the local control command conflicts with the remote control command. If there is a conflict, the fire protection cloud platform displays the local control command on the human-machine interface to reflect the priority of understanding the on-site environment.

[0041] This solution, by introducing image acquisition equipment and AI image recognition technology, can monitor the personnel on duty in the fire control room in real time. It automatically alarms when no personnel are on duty or the number of personnel is insufficient, and records the duration of the absence, ensuring that the fire control room is staffed or its status is traceable during critical moments, thus improving the standardization of fire safety management. Moreover, this solution does not simply switch control between remote and local control; instead, it deeply analyzes the head direction and movement trajectory of the personnel on duty to infer their psychological state and level of understanding of the situation. When it detects that the personnel on duty observe signals before operating, it indicates that they are acquiring information. If there is a command conflict, the system generates an early warning, effectively preventing control confusion caused by information gaps between remote and local systems. When it detects that the personnel on duty have briefly left (less than a second threshold) and then directly approach the main unit to operate it, the system determines that they have direct knowledge of the situation (e.g., they have just returned from an inspection after a situation occurred). In this case, by displaying the information without triggering an alarm, the system respects and prioritizes the rapid response made by on-site personnel based on firsthand information, avoiding frequent system warnings that could interfere with emergency response. In other non-specific scenarios (such as hasty operations after a long absence), the system generates a warning by default, effectively preventing misoperations that may occur due to the staff's impatience upon returning to duty. This achieves the optimal solution for human-machine collaboration in complex and ever-changing fire scene scenarios.
