摘　　要：针对在小数据量、弱实时性和长距离通信场合中电力载波通信电路复杂的问题,提出一种电路简单、成本低的二线制总线。利用时分复用的原理,设计了二总线能量/信息传输电路,包括通信电源电路、节点能量接收和信息调制电路。在此基础上,利用数据帧地址优先发送的原则,设计了具有总线仲裁机制的通信协议。在智能地下车库中的应用表明,该设计能够完成能量和信息的分时传输,易于工程实现。In short data frame, weak real-time and long-distance communication applications, technology of power line carrier communication is too complex to use. A two-wire bus is presented, which has simple circuit and low-cost features. Based on tinledivision multiplexing principle, the energy/information transmission circuit for the bus is designed, which includes communications power supply circuit, the node receiving energy and information modulation circuit. By using the principle that bus priority decided by the address in data frame head, a communication protocol with bus arbitration mechanism is designed. The bus is applied to a smart underground garage, which show that it works wells and is easy to implement in engineering.
