Fire warning system and method

Abstract

The invention provides a fire alarm system and method. The fire alarm system comprises a temperature measuring optical fiber, temperature measuring main station equipment, a monitoring terminal and an alarm display, wherein the temperature measuring optical fiber is used for acquiring the temperature of a conveying belt, and outputting a corresponding light signal; the temperature measuring main station equipment is connected with the temperature measuring optical fiber, and is used for supplying power to the temperature measuring optical fiber, and receiving the light signal output by the temperature measuring optical fiber; the monitoring terminal is remotely connected with the temperature measuring main station equipment, and is used for receiving and displaying temperature information and acquisition position information output by the temperature measuring main station equipment; the alarm display is connected with the temperature measuring main station equipment, and is used for receiving and displaying the temperature information and the acquisition position information output by the temperature measuring main station equipment. According to the method, the temperature measuring optical fiber is used for continuously acquiring the temperature of the conveying belt, and the temperature of the conveying belt is monitored by using the monitoring terminal, so that the function of making an alarm of the fire of the conveying belt is realized.

Description

technical field [0001] The invention relates to fire prevention technology, in particular to a fire early warning system and method. Background technique [0002] At present, in industrial and mining enterprises, most coal transportation methods are transported by conveyor belts. The conveyor belt is usually a mechanical product composed of rubber and metal. The metal material is used as the frame and transmission parts, and the rubber is used as the load-bearing part, that is, the belt. In the process of conveying coal, when the belt load is too heavy and it is pressed by coal and contacts the idler roller, due to mechanical reasons, the belt conveyor drum and idler stop rotating or the belt and idler friction heat when the speed is slow, making the conveying When the belt temperature rises, when the temperature exceeds the minimum temperature for ignition of the conveyor belt, a fire may occur. [0003] Existing systems for monitoring conveyor belt fires usually place sm...

AI Technical Summary

Problems solved by technology

[0003] Existing systems for monitoring conveyor belt fires usually place smoke sensors and carbon monoxide sensors and other equipment at important parts such as the head, middle, and end of the belt. This discrete indirect detection of smoke or carbon monoxide content after a belt fire can only be performed in After the fire is monitored, the fire has already occurred, and the early warning of the fire danger cannot be realized.
