Dovetail slot translation device and method of infrared detector for detecting unmanned or moving and static people

Abstract

The invention discloses a dovetail groove translation device of a passive infrared detector for detecting person existence or dynamic and static persons, and a dovetail groove translation method. The dovetail groove translation device consists of a solid-state relay, an electromagnet coil, a dovetail groove slide block, a dovetail groove, a reset spring and a cover plate, wherein the bottom of a dovetail groove chute is provided with a through hole, and the through hole is a window of external infrared signals of the detector; a dovetail groove translation mechanism adopts the electric driving of the solid-state relay and an electromagnet so that the detector has the function of detecting the person existence or dynamic and static persons; self-lubrication materials are adopted for manufacturing the dovetail groove slide block and the dovetail groove, and the dovetail groove translation mechanism has the advantages of multidirectional stress and less maintenance / no maintenance; a pyroelectricity infrared sensor and a signal conditioning module are reversely arranged and embedded in the slide block, the top of the slide block is flush with the top of the chute, and the gravity center of the slide block is enabled to be positioned in the chute; and two end surfaces of the cover plate are respectively designed into flat / concave surfaces, the direction of the flat / concave surfaces of the cover plate is regulated according to the installation of the top / wall of the detector, the mass production of the detector is favorably realized, users can favorably reduce spare products, and the total ownership cost is reduced.

Description

technical field [0001] The invention belongs to the detection technology category of passive pyroelectric infrared detectors, in particular to a dovetail groove translation device and a method thereof for detecting no one or moving or static people. Background technique [0002] With the rapid development of my country's economy, the lack of resources and the pace of social transformation are accelerating. On the one hand, the population flow is gradually increasing, and the social security situation is becoming more and more complicated; therefore, people pay more and more attention to the safety of life and property. On the other hand, the shortage of energy and electricity hinders the sustainable development of China's economy and will not be fundamentally improved in the foreseeable time; therefore, building a resource-saving society has become the consensus of the whole society. Taking security as an example, the traditional means of civil defense, physical defense and...

Problems solved by technology

[0010] The above-mentioned useful explorations have proposed the method of "static human body, detector moving" and "multi-sensor information fusion" to detect static human body, which has certain reference value, but the exploration results are still limited; therefore, it is necessary to use passive pyroelectric infrared Detectors, conduct in-depth research and innovation on the basis of existing research results, and realize the detection of unmanned or moving or static people with the help of simple, cheap, reliable, low / maintenance-free technology
