Gas Concentration Monitoring System Based on Soft Redundancy and ZigBee

Abstract:

The scheme based on soft redundancy and ZigBee is introduced due to the inadequacy of existing mine gas concentration monitoring system. The system is divided into underground and aerial parts. The gas concentration of mine working site can be tested automatically by underground part, which can transmit the data to the ground using ZigBee wireless communications technology. Two sets of identically configured PLC control system constitute the aerial part, which can meet redundancy requirements by procedures and directives. The solid technical support in mine safe operation can be provided based on the system, which improves the stability and reliability of the gas concentration monitoring.
