【摘要】 文章介绍一种树型嵌入式系统网络的设计方案,用单片机的一个串口与上网通信,另一个串口与下网通信,实现树型嵌入式系统网络的实时通信,并完成相应的接口电路设计以及通信原理和路径选择算法。该方案已成功的应用于KJ15A矿井机车运输监控系统中,实际应用表明,系统结构简单、易于扩展及性能稳定可靠。更多还原

【Abstract】 The design of the tree-model network of the embedded system is introduced.By using one serial port to communicate with the upper net and the other serial port with the lower net,real-time communication of the network of the embedded system is realized.The overall structure of the network,the communication principle and the design of the interface circuit are described.The hierarchical model of the network is analyzed in detail.This design has been successfully applied in the KJ15A controlling system,which proves that such network has simple structure and stable performance and can be expanded.更多还原
