Internet of things-based cable trench fire protection system

Abstract

A cable trench fire extinguishing system based on the Internet of Things, including a remote control center and several thermal aerosol fire extinguishers with electric ignition devices installed in the cable trench, each thermal aerosol fire extinguisher is equipped with a wireless communication module and an integrated address module Each control unit module is connected with its wireless communication module and piezoelectric igniter signal on the same hot aerosol fire extinguisher. The addresses set by the address modules of all control unit modules are different. The communication module is signal-connected with the remote control center; the beneficial effect of the present invention is that the structural design of the present invention is reasonable, not only can effectively prevent fire hazards in cable trenches, but also can reduce false trigger rates, improve operational stability and reliability, and ensure that equipment of normal operation.

Description

Technical field[0001]The invention relates to a cable trench fire fighting system based on the Internet of Things.Background technique[0002]One of the signs of modern cities in the world is that all cables enter the ground. This is also the current development trend of urbanization and urbanization in China. Information construction has become a national strategic plan, and information transmission facilities have become national infrastructure. Cables to the ground can not only ensure the completion of information transmission, but also have the advantages of safety and convenience. Since there are many live cables arranged in the cable trench, and the cable trench is generally closed and long and narrow, the existing cable trench has certain fire hazards, and once a fire occurs, it is easy to spread and lose control. In order to prevent fire hazards, the current plan is to install fire extinguishing equipment in the cable trench. The trigger condition of the existing fire extingui...

AI Technical Summary

Problems solved by technology

Because there are many live cables arranged in the cable trench, and the cable trench is generally closed and narrow, the existing cable trench has certain fire hazards, and once a fire occurs, it is easy to spread and get out of control

In order to prevent fire hazards, the current solution is to install fire extinguishing equipment in the cable trench. The trigger condition of the existing fire extinguishing equipment is usually temperature. There may be fires around but not triggered, which will affect the normal operation of the equipment
