Technical field
The utility model relates to a kind of electronic-controlled installation of full attitude human inductor, belongs to sensor field.
Background technology
Device as lighting energy saving control mainly contains pyroelectric infrared sensor and microwave Doppler sensor at present.But these two kinds of sensors all are the human bodies that can only detect in the motion, do not have detectability for actionless human body.
Pyroelectric infrared sensor is the working method that adopts the human body infrared signal.The infrared ray that the human heat produces focuses on the pyroelectric infrared sensor through Fresnel lens.Because signal is very faint, so pyroelectric infrared sensor adopts differential principle to design at signal processing mode.Therefore only have when human body to be under the state of walking about, just can effectively detect, do not have detectability for static human body.
The microwave Doppler sensor is based on Doppler effect.The fixed frequency microwave that hard-wired radar sends runs into the reflection wave that stationary object produces, and its frequency does not change, and Doppler shift will occur the reflection wave that runs into the moving object generation, and the change of frequency can be used for calculating relative velocity.Radar Doppler receives reflection wave signal in the launched microwave signal, and both are mixed new low frequency signal of difference frequency generation mutually, claims Doppler signal, and this signal can be used for having judged whether that mobile human body exists.Therefore this inductor also can only detect moving object.
Summary of the invention
The present invention seeks in order to remedy deficiency of the prior art; a kind of settling mode based on the human body infrared temperature sensor is provided, can detects dynamically and static human, can be widely used in lighting energy saving control and building energy management system; greatly be conducive to energy-saving and emission-reduction, protection of the environment.
