Abstract
Description
Technical Field
[0001] This invention relates to the field of traffic fire safety, and in particular to a method for remote and on-site control of fire monitors in highway tunnels. Background Technology
[0002] As a key node in the modern transportation network, highway tunnels are enclosed, long and narrow, and have dense traffic. Once a fire occurs, it is characterized by rapid fire spread, rapid smoke accumulation, sharp decline in visibility, and difficulties in evacuation and rescue. This can easily lead to secondary disasters such as major casualties, property damage, and prolonged traffic disruptions.
[0003] Existing methods for controlling fire monitors in highway tunnels rely on a "fire alarm - fire control room confirmation - dispatch of personnel to the scene" process. When a fire occurs, the automatic fire alarm system or personnel must first confirm the fire and transmit a signal to the fire control room. After confirming the fire, on-duty personnel then notify firefighters to rush to the scene. In the long and unique space of a highway tunnel, it takes time for personnel to reach the location of fire-fighting equipment, and fire monitors and other equipment are difficult to control remotely, relying solely on on-site firefighting operations. Therefore, the long fire response time is detrimental to early fire control. Furthermore... Therefore, the present invention provides a method for remote and on-site control of fire monitors in highway tunnels, so as to shorten fire response time, improve the automation level of fire monitor control, and take into account on-site control functions. Summary of the Invention
[0004] The purpose of this invention is to provide a remote and on-site control method for fire monitors in highway tunnels, so as to solve the problem that the existing fire monitor control methods in highway tunnels have long fire response time and are not conducive to early fire control.
[0005] The present invention solves the above-mentioned technical problems through the following technical solutions, the present invention comprising: A method for remote and on-site control of fire monitors in highway tunnels, comprising the following steps: S1: Assign unique numbers to the water cannon module and the camera respectively, and establish a one-to-one association between the water cannon module and the camera based on their deployment positions; S2: The camera monitors the road conditions in real time. When a fire occurs, the camera image provided by the camera determines the camera closest to the fire. S3: Based on the association between the water cannon module and the camera in step S1, determine the rotating water cannon module through the camera; S4: The fire control host sends a start signal to the rotating water cannon module through the field control box; S5: The rotating water cannon module is activated and aims at the fire point to carry out firefighting operations; S6: Monitor the firefighting operation through the corresponding numbered camera of the rotating water cannon module and adjust the control signal in real time until the firefighting operation is completed.
[0006] Furthermore, between steps S3 and S4, there is also step A1: detecting whether the working signal of the fire pump room input to the fire control host is normal.
[0007] Furthermore, in step S1, the step of assigning unique numbers to the water cannon module and the camera is as follows: S101: Starting from one end of the tunnel and ending at the other end, multiple equally spaced deployment points are divided within the tunnel. S102: Install water cannon modules and cameras at each deployment point; S103: The water cannon modules and cameras are numbered sequentially according to the tunnel's orientation.
[0008] Furthermore, the step S2, which involves determining the camera closest to the fire location using the image provided by the camera, is as follows: S201: Compare all camera images and select the image with the largest proportion of fire point pixels; S202: Locate the camera number that recorded the image and identify it as the camera closest to the fire.
[0009] Furthermore, the water cannon module includes a water inlet pipe, a water cannon solenoid valve, a water pressure push rod solenoid valve, a water pressure push rod, and a water cannon; One water inlet pipe is connected to the water cannon's water supply port via a water cannon solenoid valve; The other path is connected to the water pressure push rod via a water pressure push rod solenoid valve; The movable end of the hydraulic push rod is connected to the water cannon; The field control box is electrically connected to the water cannon, the water cannon solenoid valve, and the water pressure push rod solenoid valve, respectively. The field control box communicates with the water cannon, the water cannon solenoid valve, and the water pressure push rod solenoid valve.
[0010] Furthermore, the specific steps for the fire control host to send control signals in step S4 are as follows: S401: The fire control host sends a fire control signal to the transfer box; the fire control signal includes a water pressure push rod solenoid valve opening signal, a water cannon solenoid valve opening signal, a water cannon opening signal, and a water cannon attitude adjustment signal. S402: The relay box converts the received fire control signals, converts optical signals into electrical fire control signals, and sends them to the field control box; S403: The field control box transmits the received electrical control signals to the water cannon module.
[0011] Furthermore, step S6 involves monitoring and adjusting the control signal in real time using the corresponding numbered camera as follows: S601: Check the deviation distance between the water jet from the fire point and the location of the fire point in the camera with the corresponding number; S602: The fire control host, transfer box and field control box sequentially send water cannon attitude adjustment signals to the water cannon to control the angle, pitch and spray velocity of the water cannon nozzle, and reduce or even eliminate the deviation distance between the water cannon spray jet and the fire point.
[0012] Furthermore, the working signals of the fire pump room in step A1 include the fire power supply on / off signal, the fire pump start / stop status signal, and the fire water pressure signal; In step A1, the signals that are normal are the fire power supply on / off signal, the start / stop status signal, and the fire water pressure signal, which meet the requirements of fire-fighting operations.
[0013] Furthermore, the remote and on-site control method for fire monitors in highway tunnels also includes a voice broadcast system control step S7, specifically including: S701: Real-time monitoring of on-site firefighting operations via camera; S702: Based on the on-site firefighting operation situation, send command instructions to the voice broadcasting system through the fire control host to guide on-site firefighters in carrying out firefighting operations.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes a remote and on-site control method for fire monitors in highway tunnels. A fire control host sends fire control signals, such as the opening signal of the water pressure push rod solenoid valve, the opening signal of the water monitor solenoid valve, the water monitor activation signal, and the water monitor attitude adjustment signal, to the on-site control box via a relay box. The fire control host then controls the rotating water monitor module, achieving remote control of the fire monitor. This shortens the fire response time and improves the automation level of fire monitor control.
[0016] 2. This invention enables command and control of on-site firefighters and firefighting operations through a voice broadcast system, and allows on-site firefighters to control fire monitors through a field control box. The coordinated operation of the voice broadcast system and the field control box achieves on-site control of firefighting operations. Attached Figure Description
