【摘要】 本文介绍一种由一台PC486／586作主机、一台MCS51系统作主站、32台MCS51系统作子站的分布式数据采集通讯系统的总体实现。该系统具有有线、无线两种通讯方式以及自动转换功能。考虑到降低成本，本系统还设计了专门长线发送器、接收器电路，解决了不需中继器有线传输10KM以上的问题。更多还原

【Abstract】 This article introduce the realization of one kindcommunication network of distribute data collectionsystem which is composed of main computer with aPC486/586. main station with a MCS51 system.and 32slave-station with MCS51 system. This system havewire communication’ wireless communication and autoswitch function in two mode. In order to reduce costing, we design special transmitter and receiver circuitwith which can transmit 10KM in wire without relay.更多还原
