摘要:

介绍了一种土壤温湿度、盐度、电导率等生态水文数据采集系统。该系统以单片机为核心控制单元,结合土壤参数传感器,设计了传感器接口电路、通信时序控制、SD卡存储电路及显示电路等;同时根据黑河生态水文传感器网络试验对实验的要求,实现了基于SDI-12总线的数据采集器和传感器之间的通信协议,以及生态水文数据的测量、存储及传输。在此基础上,结合网络通信和流域数据管理平台,可以实现完整的生态水文无线传感器网络。

关键词: 数据采集系统SDI-12总线土壤参数传感器    
Abstract:

This paper gives an introduction about a new kind of data acquisition system which can collect certain kinds of eco-hydrological data such as soil temperature,humidity,salinity and conductivity.The system is based on microcontroller.The sensor interface circuits,communication timing control circuits,SD storage circuits and display circuits were designed for the Hydra Probe II soil property sensor.Based on the requirements of Eco-hydrological wireless sensor network in Heihe river basin,the communication protocol between data acquisition systems and the sensors were realized by SDI-12 bus.The Eco-hydrological data can be measured,stored and transfered by the proposed system.Combined with Network communication and Watershed data management platform,an eco-hydrological wireless sensor network can be easily realized.

Key words: Data acquisition system    SDI-12 bus    Soil property sensor
