摘  要:随着科技发展，自动化控制技术、通信技术等高新科技的成熟，人们可以拥有舒适轻松的环境来享受现代便捷的生活，并能方便的使用智能产品，来满足自己的需求。研究人员致力于智能产品的研究、设计与发明，他们希望设计的产品是现代化的、安全的、能满足人们各种需求的。在这个新时代，每个家庭每个成员都想要过安心、舒适、健康和方便的生活。随着时间的推移，越来越多的人有这样的需要，远程智能控制系统慢慢的进入了人们的视野，并飞快的发展。

在此设计中采用的是GSM网络通过手机发送短信息的指令向远程小灯等发送短信。在传送指令的过程中，只要使用短消息的频段就可以了，这样节省了电线，减少了污染，并且能够保证交互式的、智能的和安全的。每个单元的SIM900A模块和GSM模块互相连接接收用手机远程控制发来的指令，由核心芯片STC89C52RC单片机来控制。本设计主要研究的是通过手机发送短信息指令进行传输并转换为控制信号的过程，建立特定的模型，用C语言进行编译，串行端口数据稳定的传输，准确的控制系统，经过一系列的操作过后对设计的可操作性、实用性和完整性进行了验证。

The Design of Short Message Control System Based on GSM

Abstract:With the development of science and technology, the mature of high and new technology such as automation control technology and communication technology, people can have comfortable and easy environment to enjoy modern and convenient life, and can easily use intelligent products to meet their own needs. Researchers are committed to the research, design and invention of intelligent products. They want to design products that are modern, secure and meet the needs of people. In this new era, every family member wants to live in peace, comfort, health and convenience. With the passage of time, more and more people have such needs. The remote intelligent control system has slowly entered the field of vision and has been developing rapidly.

In this design, GSM network is used to send short messages to mobile phones and send short messages to remote small lights. In the process of sending instructions, the frequency of short messages is available, which saves wires, reduces pollution, and ensures interactive, intelligent and safe. The SIM900A module and the GSM module of each unit are connected to each other to receive instructions from remote control of mobile phones, and are controlled by the core chip STC89C52RC single chip microcomputer. This design mainly studies the process of transmitting and converting to control signals by sending short message instructions through mobile phones, setting up a specific model, compiling with C language, transmitting stable serial port data, accurate control system, and after a series of operations, the maneuverability, practicality and integrity of the set are made. The verification is done.
