Design of Temperature and Humidity Monitoring System for Museum Environment

该文设计了一种基于433 MHz频段无线传感器网络(WSN)的馆藏文物温湿度监测系统。系统以SI4432无线射频收发器和STM8L微处理器为核心,采用SHT15采集温湿度信息。通过设计的组网通信协议使系统具有自组网、路由自动查找及低功耗等特点。实验表明,系统能准确地监测当前环境温湿度并将采集数据发送给监控主机,且误码率及丢包率较低,通过监控机可实现对温湿度、网络状态等信息的采集、管理和分析。

A temperature and humidity monitoring system for museum collections based on WSN operating at433 MHz has been designed in this work.The system uses SI4432 wireless transceiver and STM8 Lmicroprocessor as the core,and the temperature and humidity informations were collected by SHT15.The designed communication protocol enables the system to have the characteristics of Ad hoc network,automatic routing and low-power.The experimental results show that the proposed system can monitor the temperature and humidity conditions,and automatically send the collected data to the monitoring host.The system has the features of low bit error rate and packet loss rate.The acquisition,management and analysis of the temperature and humidity data,network status can be realized through the monitor.
