【摘要】 提出了一种在分布式单片机控制系统中 ,多机间进行高性能串行通信的方案。采用 RS485串行接口标准及两级单片机主从式结构 ,实现了成本低、传输距离远、抗干扰能力强的通信。此设计方案在远程分布式安全防卫系统中得到很好的应用。更多还原

【Abstract】 The scheme of the serial communication of high performance among multi-processor is provided in the control system of the single chip processor of distributing type. Based on RS485 serial interface standard and two grades of structure of principle and subordinate type of single processor computer, communication is realized with low costs, long-distance transmission, anti-interference with strong ability. Experiment result that the design is well used in the long-distance security system.更多还原
