分布式无线土壤湿度监测系统的设计

The Design of Distributed Wireless Soil Humidity Monitoring System

设计了一种分布式无线土壤湿度监测系统,由多个从机和一个主机组成。从机负责测量点土壤湿度数据的采集,装置分布安装在一片待测土壤的多个测量点中,主机负责土壤湿度数据的收集和显示。主机和从机之间是无线双向通信。系统包括土壤湿度信息采集、无线模块、按键控制以及显示模块等部分。系统可以对一片土壤的湿度进行同时监测,其结构简单、使用方便,具有小型化、可视性好等特点,同时采用无线方式,无需馈线连接,主机和从机可以随时移动,可扩展性好。

A distributed wireless soil humidity monitoring system is designed. The system is composed of multiple hosts and a server. Host is responsible for survey points to collect the data of soil humidity, device installed in a distribution for the soil of muhiple points. The server is responsible for soil humidity data collection and display. The host and server is wireless communication. Hardware includes soil humidity information collection, wireless module, key control module and display module etc. The system can simultaneously monitor a soil. Experiments show that the monitoring system is stable, reliable, high precision, showing the value of good stability etc.
