北京理工大学珠海学院 2020 届本科生毕业设计报警系统中的通信技术与应用研究报警系统中的通信技术与应用研究摘 要当今世界，随着人民生活水平的大幅改善，广大人民群众对于家庭财产的保护显得尤为重视，为了保护居民的家庭财产、在家中出现火灾及外人进入的情况下使家人及时得到警报，设计出一种简单实用的报警器逐步成为大众日益关心的一方面。本文主要介绍的研究主要是基于 STC89C52, GSM 家庭报警安全与报警系统的设计。该系统有两个功能传感器用于检测人体入侵的 HC-SR501 传感器与检测火灾情况的MQ-2 传感器，对于警情的发生较为敏感，能够及时发现并于第一时间发出报警。而且通过添加的 GSM 模块，能向预先指定好的手机发出实时的警情信息，从而使家人第一时间得到通知，即使家中无人也能够及时做出相应措施。这种防盗器可以安装在较为隐蔽的地方来进行信号检测，而且 GSM 模块能够向手机发送报警短信，便于远程监控。本设计主要包括信息采集、信息处理、报警与 GSM 模块等部分。北京理工大学珠海学院 2020 届本科生毕业设计关键字：单片机；HC-SR501 传感器；GSM；MQ-2 传感器北京理工大学珠海学院 2020 届本科生毕业设计Research on communication technology and application in alarm systermAbstractPresent world, because of the great improvement of people's living standards, more and more people begin to pay more attention to the protection of their family property. In order to protect people's family property, in the case of fire at home and the entry of outsiders, the design of a simple and practical alarm has gradually become an increasingly concerned aspect of the public. The system is connected with two kinds of sensors, which are used to detect human body (hc-sr501 sensor) intrusion and fire (mq-2 sensor). This paper mainly introduces the design of GSM home alarm and security system based on STC89C52.It is sensitive to the occurrence of alarm, and can detect and send out alarm at the first time. So that the family can be informed at the first time, even if there is no one a...
