Intelligent cell anti-theft alarm system

Abstract

The invention discloses an intelligent cell anti-theft alarm system comprising a control module (2) with a single chip microcomputer as the core, a security sensing circuit (1) connected with the control module, and an alarm circuit (3) connected with the control module. The security sensing circuit comprises a passive infrared sensor (8), a Fresnel lens mounted on the passive infrared sensor, and a sensing signal processing integrated circuit (9) connected with the passive infrared sensor. The other end of the sensing signal processing integrated circuit is connected with the control module. The intelligent cell anti-theft alarm system further comprises a key control module (4), a self-contained power supply module (5), a display module (6) and a wireless communication module (7). Signs of human activity is detected by the passive infrared sensor and transmitted to the control module, and alarm is realized through the alarm circuit. The intelligent cell anti-theft alarm system is simple in structure, easy to implement and not high in cost.

Description
