摘　　要：针对自动化监测领域对无线通信技术的需求,提出一种基于ZigBee、GSM和PSTN的远程分布式温湿度实时监测系统设计方案;采用AT89S52单片机,IP-Link 1221-2034无线模块,DS18B20和DHT11等单总线温湿度传感器构建ZigBee无线传感器网络;以ARM7芯片LPC2114为核心,利用GSM模块TC35i或者嵌入式Modem,将ZigBee无线传感器网络监测的温湿度数据通过GSM网络或者PSTN网络传输给远程手机或计算机终端;系统具有硬件成本低廉、软硬件扩展性强、适用性广、人机交互界面友好和使用方便等优点,有一定的实用价值。Aiming at the requirement to wireless communication technology in automatic monitoring fields, a design scheme of remote distributed temperature and humidity real-time monitoring system based on ZigBee, GSM and PSTN is proposed. A kind of ZigBee wireless sensor network （WSN） was constructed by using AT89S52 MCU, wireless module IP-Link 1221--2034 and 1 wire temperature and humidity sensor DS18B20, DHTll. This system takes ARM chip LPC2114 as the core, with GSM module TC35i and embedded modem, it is able to transfer temperature and humidity data monitored by Zigbee wireless sensor network to remote mobile phone and computer terminal by means of GSM and PSTN. It has the advantages of low hardware cost, strong software and hardware expandability, extensive applicability, friendly man-machine interface, easy to use and has certain practical value.
