【Abstract】 A breakdown monitoring alarm system for the machines with closed circuit ventilation was developed in the paper. The choosing of the system as well as its working principles was expounded, meanwhile offering the circuit diagram of key units and poiniting out briefly what should be paid attention to when manufacturing such machines. The device could be directly used to monitor 8 machines with closed-circuit ventilation simultaneously, or more if necessary.更多还原
