Pyroelectric infrared detection anti-theft monitoring system

Abstract

The invention discloses a pyroelectric infrared detection anti-theft monitoring system. The pyroelectric infrared detection anti-theft monitoring system comprises a power module, a processor, a pyroelectric infrared sensor, and an audible and visual alarm module, wherein the power module is used for supplying power to the entire system, a signal output end of the pyroelectric infrared sensor is connected with a signal input end of the processor through a data line, the signal output end of the processor is connected with an input end of the audible and visual alarm module, the processor is used for processing a voltage signal of an infrared change generated by human body movement and sending an alarm signal to the audible and visual alarm module, the audible and visual alarm module issuescorresponding alarm after receiving the alarm signal, and the audible and visual alarm module comprises a buzzer module and an LED indicating circuit. Compared with the prior art, the signal collectedby the pyroelectric infrared detection anti-theft monitoring system disclosed by the invention is transmitted to a single chip microcomputer by the data line, the single chip microcomputer performs corresponding data processing, and the single chip microcomputer system and alarm system can be placed closer to a stolen person to not only alert a thief, but also alert the stolen person.

Description

technical field [0001] The invention relates to the field of photoelectric detection, in particular to a pyroelectric infrared detection anti-theft monitoring system. Background technique [0002] Campus theft cases that disrupt campus order and infringe on the rights and interests of teachers and students, and theft cases in rural areas with weak prevention and control measures occur frequently. Various theft events emerge in an endless stream, prompting people to design and develop anti-theft systems. When people talk about anti-theft, they think of monitoring, but it is not always the case. Anti-theft systems are divided into human defense, physical defense, and technical defense according to the prevention and control methods. Our common monitoring is a kind of technical defense. The common alarm detectors have active Type and passive infrared alarm, etc., are conducive to people to monitor in production and life. Due to the continuous development of science and techno...

However, the domestic alarm system is not perfect and mature enough. It is precisely because of the imperfection of the domestic system that the alarms are shoddy, which makes the installation rate of the products low, the use rate low, the alarm rate low, and even to a certain extent. The inconvenience of the people in production and life
