摘要
为了实现野外偏远、无GPRS信号地区土壤墒情、温度及降雨量的远程无线实时监测,设计了一套由土壤墒情及相关影响信息实时采集系统、铱星通信以及互联网技术构成的'物联网'架构式土壤墒情实时监测系统,围绕铱星SBD(Short burst data)终端模块9602开发了具有独立知识产权的数据采集系统。该系统实现了智能化、网络化的土壤墒情实时监测,以及历史数据的查询、下载,根据设定阈值进行短信报警、传感器和通信故障报警等功能。该系统自2011年8月在山东省、北京市等地运行以来,可以安全、稳定、可靠地获取监测土壤含水率、温度及降雨量信息。通过试验可知铱星通信在空旷地带成功率为97.2%,单个节点通信费用为每月200元(12 000字节),达到了对土壤墒情、温度和降雨量变化规律进行长期监测的目的。
In order to monitor the real-time soil moisture, temperature and rainfall in remote area where GPRS communication is not accessible, a real-time soil moisture monitoring system was designed by using Iridium communications, real-time information acquisition and Internet technology. The ＂ Internet of Things＂ architecture was founded and the self-developed Iridium transparent transmission module as well as real-time data acquisition module were designed based on the terminal module 9602 in short burst data （SBD） transceiver. It implemented intelligent, network-based real-time soil moisture monitoring, as well as historical data querying, downloading and text message alarming according to the preset threshold values. Functions such as sensors and communication failure alarm made it possible for safe, steady, reliable communications. Since August 2011, the system came into operation in Shandong Province, Beijing City and other places. System could be safe, stable and reliable to obtain the soil moisture content, temperature and rainfall. The running result indicated that the data transmission system had the advantages of high reliability, low communication fees and wide coverage. The data receiving rate could reach to 97.2 % , and the communication fee was ￥200 Yuan per month, which achieved the aim of long-term monitoring of soil moisture, temperature and rainfall.
