Full-function safety early warning device based on millimeter wave radar

Abstract

The invention discloses a full-function safety early warning device based on a millimeter wave radar and relates to the technical field of early warning devices. The full-function safety early warning device based on the millimeter wave radar comprises a supporting mechanism, an opening and closing mechanism, an equipment installation bin and an early warning device mechanism, wherein the supporting mechanism is embedded in a structural outer wall; the opening and closing mechanism is installed on the supporting mechanism, the opening and closing mechanism comprises a rectangular frame, and a door plate is hinged to the inner side of the rectangular frame; the equipment mounting bin is arranged on the inner side of the supporting mechanism, and the equipment mounting bin is located in the door plate; the millimeter-wave radar early warning device comprises a shell, a millimeter-wave radar sensor, a fire-fighting sensor module, a security and protection sensor module, an environment monitoring sensor module, a processor module, a communication module and a buzzer alarm are arranged in the shell, and through integration of the multiple sensors, sensitivity is improved, and false alarms and missing alarms are reduced.

Description

technical field [0001] The invention relates to the technical field of early warning devices, in particular to a full-function safety early warning device based on millimeter wave radar. Background technique [0002] The anti-theft alarm function of the traditional security system generally uses microwave detection or microwave plus infrared double detection to detect the human body. The number of people can easily lead to false positives or false negatives. At the same time, the detectors of the fire alarm system are mostly single-signal detection, such as smoke, temperature, gas alarm, etc. The above-mentioned systems need to be equipped with alarm hosts separately, which is costly and cannot take into account both alarm accuracy and signal sensitivity. [0003] In addition, the existing safety early warning devices generally adopt an external method, which is easy to fall into dust, and the safety early warning devices can completely stop working when there are people at...

[0002] The anti-theft alarm function of the traditional security system generally uses microwave detection or microwave plus infrared double detection to detect the human body. The number of people can easily lead to false positives or false positives

At the same time, the detectors of the fire alarm system are mostly single-signal detection, such as smoke, temperature, gas alarm, etc. The above-mentioned systems need to be equipped with alarm hosts separately, which is costly and cannot take into account both alarm accuracy and signal sensitivity.

[0003] In addition, the existing safety early warning devices generally adopt an external method, which is easy to fall into dust, and the safety early warning device can completely stop working when there are people at home, but the existing safety early warning devices are always in operation, resulting in a waste of power resources
