摘　　要：在由PC机和多台单片机构成的分布式控制系统中,通过采用MAX3162E芯片在串行通信接口电路中完成了RS-232与RS-485间的信号转换,并定义了通信协议,用VB和C51语言分别设计了PC机和单片机的串行通信程序。程序实际运行良好,具有参考与实用价值。In the distributed control system composed of PC and multi single chip microcomputers, the RS -232/RS -485 muhiprotocol transceiver MAX3162E is used in the interface circuit between them. By Visual Basic and C51 language, the communication program between multi single chip microcomputers and PC is achieved, which is based on the user - defined protocol. The tested communication program runs very well and is referential for engineers.
