摘要

本课题的任务是实现一个控制组件，用户可以通过手机发送短信对三个模块的安全进行报警，分别是设置温度的报警、电子密码锁密码输错3次的报警、红外检测外来人员的报警。控制组件主要由GSM模块TC35、液晶显示LCD12864、单片机AT89S52及温度传感器ds18b20、红外检测头组成。控制组件由主程序、按键控制程序、液晶显示初始化及功能模块程序、ds18b20检测温度程序、TC35短信程序等功能模块组成。其中主程序负责和TC35进行短消息发送，LCD12864负责显示温度、设置温度、密码锁模块、红外检测设置的工作状态。三个模块的功能、报警状态检测和短信报警是本软件的难点问题，软件设计部分将对这几个问题进行了详细的描述。本设计中，系统增加了十六个按键的矩阵键盘用于各个模块状态的选择、报警系统的设置、密码锁密码的输入等。

Intelligence Security System Design

Abstract

This paper completely implements the standard PDU encoding and decoding functions, and will give a detailed description later about that.The purpose of this paper is to design a component, which can through the phone to send a text message to the three module security alarm. They are Set temperature alarm, Password wrong three times alarm and Infrared detection alarm. The hardware of the component consists of a GSM module named TC35,a MCU named AT89S52，a Liquid Crystal Display named LCD12864, and Temperature sensor named DS18b20.

Control component by the procedures, key control procedures, liquid crystal display initialization and function module procedures, ds18b20 detection procedures, TC35 text message program temperature function module. Among them main program is responsible for and on short message sending TC35, LCD12864 responsible for display temperature, temperature, combination lock setting module, infrared detection set working condition. Three modules of the system, alarm state detection and alarm messages is the difficult problem in the software, software design part will be a few to this problem are described. This design, system increases the sixteen buttons for each module of the matrix keyboard the choice of state, alarm system establishment, the locks of the input password.

Key Word: AT89S52 SMS message GSM module TC35 Safety alarm
