Design of Gas Control System Based on MODBUS Protocol
Abstract：In view of the signal output type of infrared CH4 sensor,the advantages and disadvantages of digital signal and simulation signal are compared.The RS-485 digital signal is being chosen as sensor signal output type.The experiment results have validated the anti-interference capability of the RS-485 digital signal in complex environment of power plant.
