Tunnel fire-fighting system

Abstract

The invention relates to a tunnel fire-fighting system. Two fiber redundant token ring networks are disposed in left and right holes of an expressway tunnel and are independent of each other. A tunnel master control PLC (programmable logic controller) and a plurality of tunnel field PLCs are connected in the fiber redundant token ring networks, and a variable message sign, a lane indicator, lighting equipment, a CO/VI detector, tunnel ventilation equipment and a fire detector are in signal connection with the tunnel field PLCs, each tunnel field PLC is in signal connection with a monitor computer through the tunnel master control PLC, and the monitor computer is also in signal connection with sprinkling fire-extinguishing equipment and gas fire-extinguishing equipment in the tunnel through a DDC (direct digital control) controller; the monitor computer further transmits alarm information to wireless signal transceivers in passing-by vehicles through a wireless network and gives out warnings through a vehicular warning unit, other vehicles receiving the warning information are not more than 10km away from the tunnel in which an accident happens, and the warning information includes a tunnel name and coordinate location of the tunnel in which the accident happens and countermeasures.

Description

technical field [0001] The invention relates to a tunnel fire protection system. Background technique [0002] As a tunnel area with a relatively high accident rate in expressway sections, in order to ensure driving safety and improve driving efficiency, tunnel monitoring systems are usually installed in long or extra-long tunnels. In addition to monitoring the ventilation, lighting and driving conditions in the tunnel, when necessary In addition to releasing inductive and instructive information. At the same time, it is also necessary to build a tunnel fire linkage system to determine reasonable and effective fire safety measures. [0003] The function of the fire linkage management system is to automatically monitor the heat, light and smoke when a fire occurs in the area, so as to issue an audible and visual alarm and link the output contacts of other equipment to control the automatic fire extinguishing system, emergency broadcast, accident lighting, fire water supply a...
