specific Embodiment approach

[0040] Specific implementation method: When the rear central monitoring and control platform 2 receives an alarm message from a certain tunnel, the corresponding tunnel code on the rear central monitoring and control platform 2 turns red, and the central monitoring and control platform 2 will send query information through 4G communication To the 4G communication circuit unit in the communication control device 1 at the tunnel entrance where the fire broke out. The 4G communication circuit unit sends signals to the controller circuit unit. The communication control device 1 and the video monitoring device 9 are wired connected through a network cable, and the communication control device 1 sends the video query signal to the video monitoring device 9 near the place where the fire occurs in the tunnel, and the video monitoring device 9 monitors the video of the place where the fire occurred. The signal is sent to the communication control device 1, and the communication control...

Abstract

The invention discloses a passive autonomous water mist high-efficiency fire extinguishing system for tunnels. The system comprises a communication control device, a central monitoring and control platform, a light-emitting diode (LED) display screen, a tunnel ventilation system, a high-efficiency water-based fire extinguishing water tank, a water mist nozzle, a sensor monitoring device, an activated carbon absorbing layer and a video monitoring device. Once a fire is confirmed to be true, a fire control center is immediately notified to dispose of the fire of the tunnel, and a message is displayed on the LED display screen at a place which is 2000 meters away from the tunnel for indicating that vehicles cannot enter the tunnel. On-site disposal personnel can send commands to control a fire extinguisher to act in the area with the fire in the tunnel and send commands to control a ventilation fan in the tunnel to be opened by means of the central monitoring and control platform. The passive autonomous water mist high-efficiency fire extinguishing system guarantees the monitoring sensitivity and accuracy as well as the high efficiency of implementation of fire extinguishing, therebygreatly improving the safety around the fire in the tunnel, and further greatly guaranteeing the lives and property in the tunnel.

Description

technical field [0001] The invention relates to the field of tunnel traffic safety protection, in particular to a passive and autonomous fine water mist fire extinguishing system for tunnels. Background technique [0002] In the past 10 years, due to the ever-increasing traffic flow, improvement of road conditions and the complexity of transported goods, the fire risk of traffic tunnels has increased, causing many serious fire accidents. There are roughly three reasons for tunnel fires: 1. It is caused by the vehicle itself catching fire or two vehicles collide; 2. It is caused by the explosion and leakage of vehicles transporting dangerous goods; 3. It occurs due to the failure of electrical equipment in the tunnel. The main characteristics and hazards of tunnel fires are the large volume of smoke, rapid diffusion, random occurrence of tunnel fires, heavy road congestion, which is not conducive to rescue, rapid fire development, and difficult to control. [0003] Nowadays,...
