摘要
针对红外甲烷传感器的信号输出类型,比较了数字信号和模拟信号在传输上的优劣,选择以RS-485数字信号为传感器的信号输出类型。通过实验,验证了RS-485数字信号在电厂复杂环境下的抗干扰能力。
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.
