Background technology
At present, pyroelectric infrared sensor obtains using very widely at lighting field, and is very big to reducing the energy resource consumption effect.But because the principle of induction of pyroelectric infrared sensor, such infrared human body pick-up unit all can only detect the human body in the motion, does not have detectability for actionless human body.This defective has limited further applying of pyroelectric infrared sensor greatly, such as, desirable human inductor is just earnestly expected in the control to inner temperature of room, illumination in the building automatic.
Domestic patent Z200810067283.6 discloses a kind of thermal release electric infra-red ray human body detection device, comprises Thermoelectric Infrared Sensor, Fresnel lens, electronic circuit and travel mechanism, and described Thermoelectric Infrared Sensor is fixed in the travel mechanism.Described travel mechanism comprises driving arrangement and the bracing frame that is driven by driving arrangement, and described Thermoelectric Infrared Sensor is fixed on the bracing frame.This moving structure drives Thermoelectric Infrared Sensor and moves, and makes static human body have motion with respect to Thermoelectric Infrared Sensor.
Analyze from the structure of Fresnel lens, the lens in the vertical direction is divided into some annular regions.Each annular region is divided into some equal portions, and each equal portions is a lens unit.After light passes through these lens units, will form light and dark visible range and blind area.Because each lens unit has only a very little visual angle, is the visible range in the visual angle, is the blind area outside the visual angle.Any two adjacent lens cells are all arranged separately with a blind area and visible range, their intermittently and not overlapping and intersections.Because the such architectural feature of Fresnel lens has determined the motion of the diametric motion of the relative human body detection device of human body than circumferencial direction, has lower sensitivity.The travel mechanism of patent Z200810067283.6 adopts the mode that swings, and the most of situation of mode of motion belongs to radial motion like this, and therefore, detection sensitivity can not reach optimum efficiency.
Summary of the invention
The objective of the invention is electric rotating machine to be driven the Fresnel lens rotation, utilize the principle of relative motion, carry out the detection of static human in order to overcome weak point of the prior art.
The technical solution adopted for the present invention to solve the technical problems is:
