摘　　要：本文介绍了一种基于单片机STC89C52的主从式无线数据传输网络系统,目标是实现温度、湿度数据的实时监控。它主要研究通过无线传输方式组成单片机主从式数据传输网络,要求从机利用传感器采集所处环境的温度、湿度数据,以无线传输方式发送给主机并显示。从机电路包括湿度数据采集电路、A/D转换电路、温度检测电路、电源电路、数据发送电路。通过对单片机的按键处理,使主单片机具有轮流显示和指定显示功能。同时,为了方便监控者记录数据及美观,在主机上设计了按键显示时钟功能。This paper introduces a wireless data transmission network system which is based on master-slave STC89C52, with the goal of supervising temperature and humidity data in real time. It mainly research the wireless data transmission network which is made of master-slave single chip through the method of wireless transmission, requesting the slave single chip to collect temperature and humidity data of the environment using sensors and then send it wirelessly to the master single chip to display. The circuits of slave single chip include the humidity data acquisition circuit,the A / D conversion circuit, the temperature data acquisition circuit, the power circuit and the data transmitting circuit.The master single chip can display in rotating and specifying with the key handling of the slave single chip. Meanwhile, in order to make the monitor conveniently recording data and beautiful ,the designer designs the clock-display function in the master single chip.
