基于SIM900A的农业远程控制系统设计
摘要：
随着GSM(GlobalSystemforMobilecommunication)移动通信网络的迅速
普及，新技术的开发和应用已经提到一个十分重要的位置。短消息业务（SMS）作
为GSM网络的一种基本业务，基于这种业务的各种应用已得到越来越多的关注。
本文设计了一种基于GSM短消息的远程控制系统。在给出系统的总体设计的
基础上，设计了系统的硬件和软件，采用模块化的设计。硬件部分以单片机
C8051F340为核心，还包括单片机外围电路、SIM900A通信模块。软件部分通过
KeilC软件进行编程，实现棉蚜快速监测装置的远程控制。
基于SIM900A的农业远程控制系统通过用户手机向GSM网络发送短信，接收
用户机的控制命令对棉蚜快速监测装置的远程控制。其原理简单、方便快捷、
数据精度满足生产要求，与传统的控制系统相比有着独特的优势。
