便携式土壤墒情采集器设计
|
摘要
针对目前土壤墒情采集器存在兼容性差、精度低以及稳定性差等问题,设计了一种便携式多通信接口的土壤墒情采集器。基于FD阻抗变换原理的土壤湿度传感器和数字温度传感器可同时测量土壤的温湿度;多种通信接口设计可满足不同需求的无线数据传输。GPS用于传感器地理位置信息获取,通过蓝牙或GPRS网络可将测得土壤信息发送至手机及远程服务器,也可直接存储。试验结果表明,所设计的便携式土壤墒情采集器,具有响应速度快、稳定性高、成本低等优点,可实现土壤温湿度的便携式采集与数据的多途径传输。
Considering that there are many problems in soil moisture collectors,such as bad compatibility,low precision,and poor stability,a portable multiple wireless communication interfaces soil moisture collector is designed.The collector,based on a frequency domain impedance transformation principle soil water content sensor and a digital temperature sensor,can measure soil temperature and moisture simultaneously.Its variety of communication interfaces is suitable for wireless transmission to different needs.GPS is used to obtain geographical location information.The measured soil information can be sent to mobile phones and remote servers via Bluetooth or GPRS network.The data can also be directly stored in the local data logger.The experiment results shows that the portable soil moisture collector has advantages of fast response,high stability,low cost,etc.It can portably collect soil moisture and temperature,and transmit data through multiple channels.
