针对传统土壤p H值检测技术手段落后、数据实时性差且无法与检测现场地理信息数据融合、检测设备功能单一、灵活性差等问题,研究了一种基于GPRS的远程土壤p H值快速检测系统。集成土壤p H值参数快速检测、实时显示、远程传输等技术于一体,采用高性能、低功耗的微控制器STM32F103RBT6为核心处理芯片,ZA-SOPHA101为土壤p H值检测传感器,以GPRS网络为载体实现了现场检测数据的远程实时传输。在青海省西宁市大通县景阳镇进行了测试,结果表明:该设计结构合理、运行稳定,实现了现场土壤p H数据的快速检测以及实时远程传输,并具有精度高、灵活性强、可靠性好等特点,满足土壤p H值快速检测的应用需求。
Aiming at the problem that traditional soil p H value detection technology lags behind, the real-time data is poor and can not be integrated with the on-site geospatial information data, the testing equipment has single function and poor flexibility, a remote soil p H value rapid detection system based on GPRS is studied. Integrated soil p H value parameters rapid detection, real-time display, remote transmission and other technologies in one, the use of high-performance, low power microcontroller STM32F103RBT6 as the core processing chip, ZA-SOPHA101 soil p H value detection sensor to GPRS network As the carrier to achieve the remote real-time transmission of field test data. The test was carried out in Jingyang Town, Datong County, Xining City, Qinghai Province. The results show that the design is reasonable and stable in operation, which can realize rapid detection and real-time remote transmission of p H data in the soil and has the advantages of high precision, flexibility and reliability Good sex and other characteristics, to meet the soil p H value of rapid detection of the application requirements.
