Abstract
The utility model relates to an infrared sensor module which is composed of an infrared control circuit, a trigger switch circuit and a drive circuit. An output signal of the trigger switch circuit is transmitted to the trigger switch circuit. An output signal of the trigger switch circuit is transmitted to the drive circuit. The infrared sensor module adopts a light-shading control mode, controls relay output, provides trigger signals to other related control devices, has advantages of low cost, simple control, strong compatibility and the like, can be widely applied to control equipment of energy saving, power saving and antitheft.
Description
Technical field
The utility model relates to a kind of induction module, particularly be a kind of infrared induction module.
Background technology

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of infrared induction module is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of infrared induction module, consisted of by infrared control circuit, trigger switch circuit and drive circuit, the output signal of described infrared control circuit is transferred to the trigger switch circuit, and the output signal of described trigger switch circuit is sent to drive circuit.
Described infrared control circuit consists of by infrarede emitting diode VL and with photodiode VLS that infrarede emitting diode VL forms correlation, described infrarede emitting diode VL is in series with variable resistance RP, the output of described photodiode VLS is connected to transistor Q1, and the collector electrode of described transistor Q1 is connected with resistor R1.
Described trigger switch circuit is made of the resistance R 3 that triode Q2 and collector electrode thereof connect.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model adopts the light shading type control mode, control relay output, other related control devices provide triggering signal in order to link, have the advantages such as cost is low, control is simple, compatible strong, be widely used in energy-conservation, economize on electricity, the control appliance such as antitheft.
Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of infrared induction module of the present utility model, consisted of by infrared control circuit 1, trigger switch circuit 2 and drive circuit 3, the output signal of described infrared control circuit 1 is transferred to trigger switch circuit 2, and the output signal of described trigger switch circuit 2 is sent to drive circuit 3.
Described infrared control circuit 1 consists of by infrarede emitting diode VL and with photodiode VLS that infrarede emitting diode VL forms correlation, described infrarede emitting diode VL is in series with variable resistance RP, the output of described photodiode VLS is connected to transistor Q1, the collector electrode of described transistor Q1 is connected with resistor R1, and described trigger switch circuit 2 is made of the resistance R 3 that triode Q2 and collector electrode thereof connect.
When the infrared light path that has human body between infrarede emitting diode VL and photodiode VLS, infrared control circuit 1 recovers unimpeded, the spike blackout of the base stage of triode Q2, triode Q2 is in cut-off, its collector output is high level, relay J is not in attracting state because two ends all are high potentials.
When human body leaves infrared light path between infrarede emitting diode VL and the photodiode VLS, make triode Q2 transient switching, its collector output is low level, relay J gets electric, be in attracting state, the contact J1 of relay J is by transferring normally closed point normal battle to, and other related control devices provide triggering signal in order to link, have the advantages such as cost is low, control is simple, compatible strong, be widely used in energy-conservation, economize on electricity, the control appliance such as antitheft.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
