Abstract
The utility model discloses a novel infrared sensing device which comprises a first human body infrared sensor, a fixed frame, a logic circuit and a master control circuit, as well as a rotation device and a second human body infrared sensor, wherein the first human body infrared sensor is fixed on the outer side surface of the fixed frame; the rotation device comprises a motor and a rotating wheel; the second human body infrared sensor is fixed at the bottom of the rotating wheel; and the motor is fixed on the fixed frame and drives the rotating wheel to rotate through a rotation shaft. In the device, a static human body sensor is replaced by the human body infrared moving sensor, and relative motion is generated between an infrared test element and a static human body all the time. Therefore, the problem that a senor clamps a human body can be thoroughly solved, and relative motion (vibration and rotation) can be generated between the infrared test element and the static human body all the time by virtue of the principle of relative motion, thus an infrared scanning and searching function can be realized, and continuous output of the human body infrared sensors can be achieved.
Description
Technical field
The utility model belongs to new infrared induction field, is specifically related to be used for the new infrared induction installation in field such as induction door recloser.
Background technology
Infrared inductor is used for a lot of fields; Be to be used for induction door by what people knew mostly; What general induction door was used is human body infrared inductor or microwave remote sensor; The human-body infrared sensing device is thermally sensitive sensor, and this sensor is used for its advantage of induction door: when human body and sensor had relative motion, sensor had signal output.Shortcoming: motionless if human body gets into detection zone, sensor does not just have signal to export.So induction door folder people's problem can occur.
Though microwave remote sensor sensitivity is high, to the output of static people, animal also no signal, induction door folder people's phenomenon can appear also.
For security consideration, we need provide a kind of when human body entering surveyed area is motionless, and sensor also will have signal output to avoid induction door folder people's potential safety hazard to occur.
The utility model content
The purpose of the utility model provides a kind of new infrared induction installation, and this device becomes the static human body sensor and is human body infrared moving sensor, lets and produces relative motion between infrared detection device and static human body always.Thoroughly solve induction door folder people's problem, it is than microwave remote sensor better effects if.Overcome the weakness of original infrared sensor and microwave remote sensor.
Utilize relative motion principle, let produce relative motion (vibration, rotation) between infrared detection device and static human body always, thereby realize the noctovisor scan search function, make human infrared sensor accomplish free of discontinuities output always.
For realizing above-mentioned purpose, the utility model provides a kind of new infrared induction installation, comprises the first human body infrared inductor, fixed frame, logical circuit and total control circuit.
A kind of new infrared induction installation also comprises the wheelwork and the second human body infrared inductor, and the said first human body infrared inductor is fixed on the lateral surface of said fixed frame, and the said second human body infrared inductor is arranged on the said wheelwork.
Said wheelwork comprises motor and runner, and motor is fixed on the said fixed frame, and said motor drives said runner through rotation axis and rotates, and the said second human body infrared inductor is fixed on the bottom of said runner.Said runner is left-right rotation in 180 ° scope.
The said second human body infrared induction produces relative motion with the people before the people is still in induction door, said second infrared inductor is passed to logical circuit with signal, and logical circuit reaches total control circuit with signal again, the unlatching that sense of control is answered the door.
The utility model has overcome the shortcoming of human body infrared inductor and microwave sensor; Utilize relative motion principle; Become the static human body infrared sensor and be the movement human infrared sensor, let produce relative motion between infrared detection device and static human body always, thoroughly solve induction door folder people's problem.
The utility model also is applicable to and is used for the infrared anti-theft alarm device, and sensitivity is higher, can be used for the infrared automatic camera device of free of discontinuities, can solve classroom illumination lamp intelligent controller, have the people the time phenomenon of cutting off the power supply automatically also appears.

Wherein, the 1-first human body infrared inductor, the 2-second human body infrared inductor, 3-fixed frame, 4-motor, 5-runner, 6-rotation axis.
Embodiment
Like Fig. 1, shown in 2,3; When the new infrared induction installation in the present embodiment is used for induction door, comprise the first human body infrared inductor 1, the second human body infrared inductor 2, fixed frame 3, wheelwork; Logical circuit and total control circuit are fixed on the first human body infrared inductor 1 on the lateral surface of fixed frame 3, and wheelwork comprises motor 4 and runner 5; Motor 4 is fixed on the fixed frame 3; Motor 4 drives runner 5 through rotation axis 6 and rotates, and the second human body infrared inductor 2 is fixed on the bottom of runner 5, and runner 5 is left-right rotation in 60 ° scope.
Like Fig. 3, shown in 4, when the people is static stand in induction door before the time, the first human body infrared inductor 1 sends the infrared signal search circuit; Runner 5 in the wheelwork is through motor left-right rotation in 60 ° scope; Because the second human body infrared inductor 2 in the bottom that is fixed on runner 5, along with runner 5 carries out side-to-side movement in 60 ° scope, just in time and between the static human body produces relative motion; Make the human body infrared inductor accomplish unremitting output always; The signal that produces is sent to logical circuit, and logical circuit sends the band total control circuit with signal again, and induction door is opened then.
Utilize relative motion principle, become the static human body infrared sensor and be the movement human infrared sensor, let produce relative motion between infrared detection device and static human body always, thoroughly solve induction door folder people's problem.
