摘要

设计了一种基于无线透传传感网络的分布式环境监测系统.设计采用1100E射频芯片作为无线收发芯片,通过在ATmega128L微处理器中编写透传算法程序,实现对各环境参数的数据透传,使用RS 232C串口与PC机进行通信,实现了对目标监测区域各环境参数的实时采集.给出实验测试采集到的多组数据,通过对实验数据的分析,说明该设计可以在400 m内同时实现对254个无线节点的实时监测,测量误差约为±0.1%~±3%.%A distributed environment monitoring system based on wireless transparent transmission sensor networks was designed. A 1100E RF chip is taken in this design as a wireless transceiving chip. The data transparent transmission of the pa-rameters in various environments is realized by writing transparent transmission algorithm routine in ATmega128L microproces-sor. Real-time acquisition of parameters in target mornitoring region and various environments was implemented by using RS-232C serial port and PC to communicate. Multi-group data acquired by experiment test are presented. The analysis of the experi-mental data illustrates that this system can achieve real-time monitoring of 254 wireless nodes simultaneously within 400 meters, and the measurement error is about ±0.1% ~±3%.
