本文提出了一种基于ZigBee无线技术的校园供暖温度监测系统方案，并设计出了相应的无线传感器节点。本方案中使用基于AD590的温度测量电路，PIC16F877A微控制芯片和MRF24J20无线芯片搭建无线传感器网络。该无线传感器网络由一个位于控制室的协调器充当中心节点及若干个置放于各楼层暖气片旁的终端节点一起，构成一个星型网络。-In this paper, a ZigBee-based wireless technology campus heating temperature monitoring system programmes, and to design the corresponding wireless sensor nodes. The programme based on the use of the AD590 temperature measurement circuit, PIC16F877A chips and micro-control structures MRF24J20 wireless chip wireless sensor networks. The wireless sensor networks in the control room by a coordinator to act as the central node and several placed in each floor Heating-node next to the terminal together, constitute a satellite network.
