摘　　要：采用了基于正交频分复用技术的电力线通信(PLC)调制解调器MAX2990构成的自动抄表系统(AMR),可实现大型公共建筑的水、电、气、空调等能耗数据的自动抄送;通过码分多址模组CM800A实现数据的远程传输,本系统能实时监测现场环境变量(温湿度,风速,水流量)并实现相应控制;实验数据表明,本系统具有较强的抗干扰能力、较高的带宽利用率和较快的响应速度。A automatic meter reading system with OFDM--Based Power Line Communication Modem MAX2990 is presented. The system can collect data of water, electricity, gas and air-conditioning power consumption remotely from large-scale public buildings by using the CMS00A based on CDMA, and can supervise Real--timely environmental variables, such as temperature, humidity, wind speed and water flow rates and implement the corresponding control. Experimental data shows that the system has stronger anti--interference capability, higher bandwidth utilization and faster response time.
