基于GPRS的茶园环境参数无线监测系统的设计

Design of Wireless Monitoring System for Tea Farm Environmental Parameters Based on the GPRS

茶园一般建在比较偏远的山区,所以对茶树的管理以及获悉茶树周围每天的生长环境便是一大难题。针对这一情况,设计了一套基于GPRS茶园环境参数的无线监测系统,能够监测茶园大气温度、湿度,土壤温度、含水量以及光照强度等环境参数。该系统硬件部分包括太阳能供电、单片机控制、A/D转换、数据采集与处理、GPRS无线传输5个模块。软件通过KEIL C51进行C程序的编写与调试,主要包括环境参数的采集与处理、数据的无线传输及利用TCP进行网络通讯。采用LabVIEW 8.20开发环境进行上位机监测中心人机界面设计,调用LabVIEW里的文件输入输出函数建立数据库,对茶园环境参数进行每日每月定时的储存与访问,以便对茶树的生长环境进行连续监测。

In genera,tea garden constructions are in remote mountain area,so the management of tea tree and grasp the every day growth environment of tea tree is a major problem.In view of this situation,this paper designed a set of wireless detection system based on GPRS environmental parameters of tea garden.It can monitor atmospheric temperature,humidity,soil temperature,water content and light intensity and other environmental parameters in tea garden.The hardware part of this system includes solar power supply and single-chip microcomputer control,A/D conversion,data acquisition and processing GPRS wireless transmission five modules.The preparation and debugging for the C program of the Software through the KEIL C51,mainly including environmental parameters of the acquisition and processing,the data of wireless transmission and the TCP network communication,adopting the LabVIEW8.20 development environment for PC monitoring center the man-machine interface design,calling LabVIEW files from the input/output function,to establish the database of the garden environment parameters for the daily tea time per month of storage and access,so as to continuous monitoring the growth environment of the tea tree.
