【摘要】：由于农田的环境气候较为多变,农田环境较为开阔,使得实时采集农田气候要素信息成为难题。针对如何解决上述难题,本文设计了一套农田气候自动观测系统,旨在实现农田气候要素的实时采集、实时查询、数据存储,为农田管理者、农业研究者等提供农田气候观测数据。观测系统应用的技术包括嵌入式技术、传感器技术、电路电子技术、无线通信技术。观测系统的应用场景为农业大田环境。观测系统包括两个主要部分,分别为农田气候要素数据采集器和业务端软件。农田气候要素数据采集器包括主采集器和分采集器两部分。主采集器以AT9263芯片为控制核心。采用高精度模数转换芯片完成模拟量到数字量的转换工作。同时具有GPRS无线传输功能和CF卡接口,保证数据的实时上传和长期存储。分采集器以STM32为控制核心,以工业级IC设计信号处理电路。当分采集器接收到主采集器的命令时,将采集数据传送给主采集器。业务端软件以Labview为开发平台。实现农田气候要素的实时观测和命令的下达。操作简单,界面友好,方便管理人员对农田气象要素观测数据的监测和掌握。
[Abstract]:Because the climate of farmland is changeable and the environment of farmland is open, it is difficult to collect the information of farmland climate elements in real time. In this paper, an automatic observation system of farmland climate is designed, which aims to realize the real-time collection, real-time query and data storage of farmland climate elements. Agricultural researchers and so on provide farmland climate observation data. The application technology of observing system includes embedded technology, sensor technology, circuit and electronic technology. Wireless communication technology. The application scene of the observation system is the agricultural field environment. The observation system consists of two main parts. The farmland climate factor data collector consists of two parts: the main collector and the sub-collector. The main collector takes AT9263 chip as the control core and adopts high precision. The analog to digital conversion chip has the function of GPRS wireless transmission and CF card interface. To ensure the real-time upload and long-term storage of data. The divider uses STM32 as the control core and IC as the industrial level to design the signal processing circuit. When the divider receives the command of the main collector. The acquisition data is transmitted to the main collector. The software of the service side takes Labview as the development platform to realize the real-time observation of farmland climate elements and the issuance of commands. The operation is simple and the interface is friendly. It is convenient for managers to monitor and master the observation data of farmland meteorological elements.
