Design of an important regional alarm system based on Internet of things

Abstract With the rapid development of science and technology, we become more and more prominent security requirements for some of the important region is more so。 Therefore in the Internet of things is a trend in the widely used under, this topic will alarm system and IOT combination, develop a IOT based communication alarm system, not only to meet the market demand, more convenient for people's lives。

In this paper, firstly, the research status of related technology and research is described, and then the infrared detection technology and ZigBee technology are introduced。 After on the subject of the system design, the design mainly uses the infrared detection technology to enter the region important for personnel detection, voice prompts for a password, through wireless communication technology will send the information to the monitoring center to verify the detection to the legitimacy of the identity of the person, so as to construct the warning system based on the Internet of things。 This design respectively from the hardware, software, the two part of the in-depth study。 In the aspect of hardware, the system for all the points for infrared detection module, voice alarm module, wireless communication module, MCU control module, each part of the hardware circuit are expounded in turn; in terms of software, mainly from the wireless communication module, MCU control module and keyboard design and scanning process three aspects to carry on the design。

This paper has 20 figures, 2 tables, 23 references。
