摘　　要：设计了一种基于LonWorks电力载波技术的控制器,通过双频窄带传输克服了电力线传输高噪声、高衰减、高失真和阻抗变化问题,实现了数据在电力线上可靠通信。控制器采用主机AT89S51和从机TMPN3150作为智能处理核心,分析了在Slave_B并行接口模式下数据在主机与从机之间的传递。通过数字信号处理器等附加器件,控制器完成向电力线上发送与接收数据。试验表明,LonWorks电力载波控制器具有良好的性能。A controller based on LonWorks power line carrier technology was designed, which can achieve re- liable data transmission through a dual carrier and narrow band frequency capability to solve noise sources, attenua- tion, distortion and impedance changes. Intelligent processing core of the controller was constituted by master pro- cessor AT89S51 and slave processor TMPN3150 and data was communicated with Slave B parallel transmission mode. The controller sent data to power line and received data from power line using digital signal processors and additional devices. The experiments shows that the controller has a good performance.
