为了保障电梯安全可靠运行,提出了一个电梯温湿度测控系统;系统节点的微处理器选用了Atmega128L,无线收发器选用了CC2420,温湿度传感器使用了SHT11,传感器节点之间通信协议使用了6LoWPAN,能直接与互联网上的终端用户进行点到点的通信;系统实现了对电梯温温度的测量控制、超限报警、数据统计分析等功能,解决了电梯安装运行空间小,不便布线的问题;经验证,本系统的温度测量精度为±0.4℃,湿度测量精度为±0.3%RH,系统数据传输质量可靠,投资少、方便扩展、实用性强,能满足电梯温湿度监控需求。

In order to ensure safe and reliable running of the elevator, proposed a elevator temperature and humidity monitoring and con- trol system. The system used Atmega128L as microprocessor, used CC2420 as wireless transceiver, used SHTll as temperature and hu- midity sensors, used 6LoWPAN as communication protocol between sensor nodes. Sensor nodes can directly communication with end users for point to point on the Internet. The system realized the monitoring and control of the temperature and humidity, transfinite alarm, data statistics and analysis, and other functions, resolved the problems of small installation and running space and inconvenient cabling. The ex- periment result shows the system＇ s temperature measurement precision is ± 0. 4 % and humidity measurement accuracy is ± 0.3 %R H, da- ta transmission quality is reliable. The system has the advantages of low investment, easy extension, strong practicability, can satisfy the demand of elevator temperature and humidity monitoring and control.
