An Intrinsic Safe Design for the Coal Mine Gas Explosion-Proof Monitoring
Abstract:
The explosion-proof monitoring system of oxygen content usually is used situates in an explosive mine gas explosion monitoring site, the spark and thermal effects in its monitoring circuit are likely to form dangerous explosion source. Based on the intelligent control technology of MCU(msp430) and radio data transmission technique, this mine oxygen content monitoring system was designed according to the highest mining explosion-proof standards, so that its monitoring circuit can meet the intrinsically safe explosion-proof requirements. That is, when the hardware circuit of a explosion-proof monitoring of oxygen content was designed, the factors for limiting the heat source energy with forming the spark and thermal effects must be considered seriously.
