摘　　要：在采用电力线进行供电的工业环境中,通信布线以及通信距离的限制越发显现,但直流电力线载波通信的方式以布线方便、通信稳定、传输距离远等优势逐渐成为人们的选择。所设计的低压直流电力线载波通信系统采用PWBS751和PWBS331分别作为整个低压直流电力线载波通信的主机、从机模块,配合外围直接耦合电力传输线的载波电路,实现载波信号在低压直流电力线上的全幅DC电压脉冲半双工通信。最后还对搭建好的低压直流电力线载波通信系统进行最高传输速率和稳定性测试,测试结果验证了该载波系统设计的可行性和可靠性。In the industrial environment where power is supplied through power lines,the limitation of communication wiring and communication distance is more and more apparent.However,the DC power line carrier communication has gradually been accepted because it has the advantages of convenient wiring,communication stability,long distance transmission,etc.The low-voltage DC power line carrier communication system designed in this article uses PWBS751 and PWBS331 respectively as the host and the slave module,which work with the external direct coupling power transmission line carrier circuit to achieve full-size DC voltage pulse half-duplex communication for a carrier signal on low-voltage DC power line.Finally,the highest transmission rate and stability are tested for the established low-voltage DC power line carrier communication system.The test results verify the feasibility and reliability of the designed carrier system.
