摘　　要：针对环境监测系统布线复杂、数据的实时性和准确性低等问题,提出了一种基于ZigBee技术的分布式传感器网络平台。选用SHT75传感器实现对监测点温湿度信息的精准采集,并通过由CC2530芯片和CC2591射频前端组建的ZigBee网络完成数据的远距离传输和汇聚。数据经过阈值比较,可以进行声光报警或GSM短信报警。同时,采集的温湿度信息将通过Z-SensorMonitor软件在PC端实时显示和存储。本系统提高了数据的实时性和可靠性,降低了环境监测成本。Aiming at such problems as complex wiring, and low real-time performance and accuracy of data in environment monitoring system,a distributed sensor network platform is designed based on ZigBee technology. It uses SHT75 sensor to achieve the accuracy col- lection of temperature and humidity information,and uses ZigBee network formed by CC2530 chip and CC2591 RF front end to achieve long-distance transmission and accumulation of data. After data is compared with threshold, sound and light alarm or GSM SMS alarm is realized. At the same time,collected temperature and humidity information are displayed and stored on PC though Z-SensorMonitor soft- ware. The system improves real-time performance and data reliability, and reduces environmental monitoring costs.
