Design of standby power supply for monitoring and controlsystem for refuge chamber
LIU Ya-hui
Abstract：To ensure at least 96 hours normal functioning of standby power supply during the blackout in coal mine refuge chamber,according to the various kinds of equipment monitoring system,and the low power consumption of single equipment,an intrinsically safe standby power supply was designed.The hardware and software design was introduced in detail,the hardware design comprised standby battery pack,charging circuit,output protection circuit and power management circuit.The power supply can reduce the loss of the energy transfer process,improve use efficiency of the battery,reduce the weight and installation difficulty,and improve the reliability.
