Problems solved by technology

In the past anti-theft systems, technical measures such as pyroelectric and microwave were generally used to collect human body intrusion signals. These have good results when applied indoors. The proposed measures have a very high rate of false alarms in actual use, and sometimes even fail to work properly

Abstract

The invention relates to the technical field of safety protection and provides an infrared safety protection alarm device. The device comprises an infrared transmitting circuit and an infrared receiving alarm circuit. The device disclosed by the invention is used for the technical field of safety protection.

Description

technical field [0001] The invention relates to the field of security technology and provides an infrared security protection alarm device. Background technique [0002] In industry and agriculture, fire protection, banking, hotels, shopping malls, aerospace and other departments, it is often necessary to monitor and alarm the environment to prevent theft. For banks, hotels, etc., anti-theft alarms are even more crucial. In the past anti-theft systems, technical measures such as pyroelectric and microwave were generally used to collect human body intrusion signals. These have good results when applied indoors. The proposed measures have a very high rate of false alarms in actual use, and sometimes even fail to work properly. [0003] We know that in the conventional environmental parameters, human intrusion detectors are very susceptible to changes in parameters due to the influence of the environment. With the maturity of infrared and laser technology, many infrared...
