摘要
及时准确地获取田间信息是实现农田智能化管理的前提,是精细农业发展的基础。为解决田间信息的远程获取与无线传输问题,提出并实现了一种田间信息的远程获取与无线传输系统。同时,主要介绍了系统的组成以及工作原理,设计了土壤墒情站硬件及组成,阐述了自动气象站数据传输方式的选择。在该系统中,利用GPRS DTU实现了远程计算机、数据采集器之间的数据传输。
Getting the accurate farm information in time is the premise of intelligent management farm land. However, it is the foundation of the development of precision agriculture. In order to solve the problem of the information of remote ac- quisition and wireless transmission in the field, I put forward and implement a kind of the system that can get long range information and transmit information by using wireless means. The main centre of this paper is the content of the system and working principle. I design the soil moisture station of the hardware and content. In addition, I state the choice of transmission mode of the automatic weather station. In this system, I finish the data transmission between remote computer and data acquisition unit by using GPRS DTU.
