Infrared temperature measurement-based multifunctional human sensing switch and implementation method therefor

Abstract

The invention discloses an infrared temperature measurement-based multifunctional human sensing switch and an implementation method therefor. The multifunctional human sensing switch comprises an array type infrared thermopile sensor, a main control chip, a wireless transmitting and receiving circuit, a relay, an alarm device and a voltage converting circuit, wherein the array type infrared thermopile sensor is used for measuring heat source temperature information in a room; the heat source temperature information comprises information of a human body moving state, a human body stationary state and high temperature heat sources such as human body temperature, flame and the like; a state of the relay can be controlled via a main controller and the wireless transmitting and receiving circuit, and alarms are timely sent out upon presence of the high temperature heat sources such as the flame and the like; effects of energy conservation, environment protection, fire hazard early warning and the like can be fulfilled; a problem that a traditional infrared pyroelectric sensor-based human sensing switch can only detect dynamic human bodies while stationary human bodies cannot be detected and only one function can be provided can be solved; the multifunctional human sensing switch and the implementation method therefor are wide in application scope and good in effects.

Description

technical field [0001] The invention relates to the technical field of infrared sensing, in particular to a multifunctional human-sensing switch based on infrared temperature measurement and a realization method thereof. Background technique [0002] Most of the traditional human-sensing switches use infrared pyroelectric sensors, which can only detect the dynamic human body. Once the person is in a resting state, misjudgment will occur, and the traditional human-sensing switch does not have the ability to detect the temperature of multiple points in the area. Function, so it does not have the function of fire and human body fever alarm, so the scope of application is narrow, and the user experience effect is not good. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The purpose of the present invention is to provide a multi-functional human-sensing switch based on infrared temperature measurement and its reali...
