摘　　要：传统的温室监控系统主要采用RS485总线构成,无法满足大型林业企业对分布在不同地理位置的各个温室生产基地进行集中监控和管理的需求。为此,进行了改进和扩充,并将其应用到林业幼苗抚育温室的管理过程中,方法如下。首先利用各类传感器对温室环境参数进行测量,采用了STC单片机对测量的模拟量进行采集与前期处理,处理后的数据经过RS485通讯网络向上传输,通过GPRS模块实现监控系统与Internet网络的无缝连接,在远端集中管理、显示数据,使系统整体性能得到充分的提高,跨地域的远程监控成为了可能。The traditional monitoring system for greenhouse mainly adopts RS-485 bus,which cannot meet the requirements of large forestry enterprises＇ centralized monitoring and management for distributed greenhouse production bases.This paper introduces a kind of GPRS-based remote monitoring system which improved and extended the traditional type in order to be applied in the management process of forest seedling and tending in greenhouse.This system will measure the parameters of greenhouse through various sensors and then use STC microcontroller to collect and pre-process the analogues that measured from above,and finally transmit the processed data for communication through RS-485 bus.Thanks to the GPRS module which realizes the seamless link between monitoring system and the Internet,the system can transmit data remotely,and display data in remote centralized-managing computers.And this could fully improve the whole system performance,making remote monitoring across region possible.
