The system of the intelligent burglar alarm

Abstract：With the continuous penetration of modern science and technology, people gradually began to pursue a high quality of life with health, comfort, safety, and convenience. With the fast-paced life, although the social level has improved, there have been many destabilizing factors along with it, and family security risks cannot be underestimated. Traditional safety precautions are too simple and have not been effective in modern society. Therefore, for the development of smart homes, it is particularly important to use electronic and communication technologies to achieve a more complete security system.

This design is to establish a home fire alarm system based on GSM short message module. This article elaborates the design of the hardware and software part of the whole system, the types of selected components, the circuit design of each module and the overall circuit connection. 51-chip microcomputer system, pyroelectric infrared sensor and smoke sensor are used to detect the intruded signal. When the two modules detect the signal, the system sends alarm information through the GSM module and realizes the remote alarm function. Through tests, it has been proved that the designed system is reliable, stable in operation, convenient in operation, simple in hardware structure, and high in cost performance. It can meet the needs of fire and theft prevention and has wide application prospects.
