86 type infrared sensor apparatus with tunable detection directions and angles

Abstract

The invention discloses an 86 type infrared sensor apparatus with tunable detection directions and angles. The apparatus herein includes a probe assembly, a console assembly, a power supply module, an assembly panel, a probe wire harness and a power supply wire harness. The probe assembly is composed of a signal processing plate, a Fresnel lens and a through hole core. The through hole core is of a through structure therein. The signal processing plate and the Fresnel lens are mounted inside the through hole core. The probe assembly is mounted between a semi-spherical pedestal and a locking ring. The semi-spherical pedestal is at the front end of a box body with a pedestal. The probe assembly can move up and down to tune detection directions and locks the locking ring. A rectangular cover which is at the front end of the through hole core can limit direction angles. According to the invention, the apparatus herein can be installed to most of 86 type electrical panels that meet industrial standards, and can be installed after perforating blank panels. The apparatus herein is different from 86 type infrared sensors that are commonly seen in market in that the probe assembly of the apparatus herein can freely tune detection directions and detection angles, so that the apparatus herein is very advantageous in places that require precise positioning of body moving objects.

Description

technical field [0001] The invention relates to the technical field of passive human body pyroelectric infrared sensing, which can be used for indoor human body moving target positioning, and can also be used for security intrusion detection, energy-saving lighting and other related fields. Background technique [0002] my country has entered an aging society, and the proportion of vulnerable groups such as the elderly living alone and the widowed elderly is relatively high. Especially when accidents occur in home life, it is usually not easy to be discovered by the outside world in time, and even serious consequences may occur. Care for such vulnerable groups can be achieved through the innovative application of guardianship technology. Passive human body pyroelectric infrared sensing technology is widely used in the fields of security detection and energy-saving lighting. Provide convenience for the guardianship of special groups such as widows, widows, and the elderly. ...

AI Technical Summary

Problems solved by technology

In practical applications, a series of design and technical issues such as directional detection, signal forwarding and power supply wiring need to be dealt with. The probe part of the traditional 86-type infrared sensor is a fixed structure, which has a large detection angle and poor directional ability, especially when installed in In the suspended ceiling position, the orientation effect is worse
