Wireless intelligent tunnel fire monitoring system and method

Abstract

The invention discloses a wireless intelligent tunnel fire monitoring system and method, and a wireless communication mode is adopted. The method comprises the steps that a main controller is arranged on the side of a fire protection control room to conduct tunnel fire situation monitoring and fire protection linkage control over a tunnel fire; a plurality of fan controllers are arranged on the side of a fan; a plurality of fire detectors and fire alarms are arranged in a tunnel, and a fire broadcast controller is arranged in the tunnel; a plurality of signal relay transmission units (router) are arranged between the controllers and the main controller arranged on the side of the fire protection control room, and the signal relay transmission units are used for signal relay transmission between the controllers and the main controller arranged on the side of the fire protection control room; a tunnel fire condition is monitored under a normal situation; and when a situation of fire protection linkage occurs, the fan is controlled to conduct fire protection, smoke exhausting, fire alarming and fire fighting broadcast starting. The wireless intelligent tunnel fire monitoring system has the advantages of strong anti-interference, automatic monitoring, convenient installing and debugging, low maintaining cost and the like. The control requirements of reliability, anti-interference and stability on the tunnel fire monitoring system are met, and the wireless intelligent tunnel fire monitoring system can be applied to a tunnel fire protection and ventilating system widely.

AI Technical Summary

Problems solved by technology

[0002] At present, various tunnel fire-fighting and tunnel ventilation systems that appear on the market mainly adopt simple wired control mode to realize the functions of tunnel fire-fighting and tunnel ventilation. Large amount of system construction, high system installation and maintenance costs

With the continuous expansion of the scale of my country's fire protection industry, the improvement of fire protection industry technology and the development of intelligent fire protection, the traditional mode of tunnel fire protection and ventilation control using wired monitoring is becoming more and more difficult due to its shortcomings such as anti-interference and difficult installation and maintenance. Can not meet the monitoring requirements of modern fire protection system

At the same time, in order to master the status data of the field equipment, the tunnel fire control and ventilation control room needs to monitor the operation status of each field equipment and communicate with the fire control host. Since the tunnel fire protection and tunnel ventilation equipment are in a distributed state, the existing wired monitoring The network can no longer adapt to the requirements of the new monitoring mode

[0003] At present, the wired tunnel fire monitoring system uses the monitoring network of RS485 and other buses. This system uses a bus network. When a node in the network fails, it will affect the operation of the entire network. Its reliability, real-time And anti-interference and poor network scalability, it is not easy to monitor the expansion of the network scale

Some systems also use other network structures (such as CAN monitoring network) to improve the performance of the monitoring system to a certain extent, but still use wired network systems, and the anti-interference and reliability of the system are still not high
