Problems solved by technology

[0006] Currently, the market Early warning radios have a single function, mostly for rural economic construction, and are mainly used for early warning of natural disasters. However, automatic alarm devices are mostly used in mines, which can only have a passive effect on early warnings inside mines, and cannot actively monitor mines. Early warning, unable to meet market demand

Description

technical field [0001] The invention relates to an early warning broadcast system, in particular to a multifunctional early warning broadcast system. Background technique [0002] Mine should establish and maintain safety risk pre-control management procedures to comprehensively identify various hazards in the mine production system and operation activities, clarify the possible risks and consequences of hazards, and classify, classify, monitor, Early warning, control, and accident prevention. [0003] Mine gas explosion is a heat-chain reaction (also called chain reaction). When the explosive mixture absorbs a certain amount of energy (usually the heat energy given by the ignition source), the chain of the reaction molecule is broken and dissociated into two or more free radicals (also called free radicals). Such free radicals have great chemical activity and become active centers for continuous reactions. Under suitable conditions, each free radical can be further ...
