摘　　要：本研究针对沼气发电工程监测系统的现实需求,提出了一套由多传感器数据采集、无线数据传输、无线接收数据与PLC监测系统组成的系统装置。该系统将采集的温度、压力、流量与pH值等信号,转换成数字信号后经nRF401无线数传模块传送至PLC控制器,PLC控制器处理数据后,将其保存至计算机的数据库中,并实时显示动态曲线。测试表明该系统操作简单、稳定性好,能够实现沼气发电工程的信息监测功能。According to the real demands of biogas power generation project monitoring system, this paper puts forward a set of system device consisting of multisensory data acquisition, wireless data transmission, wireless data receiving and PLC monitoring. The system can collect the temperature, pressure, flow rate and pH signal, converted into digital signals and transmit them to PLC controller by nRF401 wireless module. After processing data, PLC controller saves it to a computer database and displays the dynamic curve. The test shows that this system has the advantages of simple operation, good stability and can realize the monitoring function of biogas power generation project.
