Fig. 2 is the limited block synoptic diagram of controller;
Fig. 3 is the control block diagram of infrared inductor.
Embodiment
Combine accompanying drawing that the utility model is described further at present:
With reference to Fig. 1-3; A kind of infrared inductor of static human body; Comprise the installation chassis 1 of installing and fixing, play the shell 2 that holds with protective effect, the power lead that is connected with the outside, signal wire, ground wire; And the Fresnel lens 3 that carries out optical focus, carry out the pyroelectric infrared sensor 9 of human infrared radiation induction and carry out central controlled controller 8.
Described pyroelectric infrared sensor 9 is installed on the described controller 8; Described pyroelectric infrared sensor 9 is arranged on the optical centre of described Fresnel lens 3; Described controller 8 is installed on the described installation chassis 1 through turning axle; Described power lead, signal wire, ground wire are connected with described controller 8; On described installation chassis 1, electric rotating machine 5 and gear train are set; Described electric rotating machine 5 is connected with described controller 8, and described electric rotating machine 5 drives described Fresnel lens 3 and described controller 8 rotations through described gear train, and the sense of rotation of described controller 8 sense of rotation and described Fresnel lens 3 is opposite.Through with described Fresnel lens of reverse rotation 3 and controller 8, can make static human body is the states that are in relative motion with respect to described pyroelectric infrared sensor 9, and reaches certain speed, so just reaches the purpose of detection static human.
On the described installation chassis 1 mounting bracket 4 is set, described mounting bracket 4 fixing described electric rotating machines 5.
