Description of drawings
Fig. 1 is a specific embodiment of the invention course of work synoptic diagram;
Fig. 2 is the structural representation of the specific embodiment of the invention.
Embodiment
As depicted in figs. 1 and 2, a kind of thermal release electric infra-red ray human body detection device comprises Thermoelectric Infrared Sensor 3, Fresnel lens 7, travel mechanism and electronic circuit.The electronic circuit of Thermoelectric Infrared Sensor is prior art, and is not shown.Travel mechanism comprises drive unit and bracing frame 2.Drive unit is a motor 1, and driving mechanism also can be other equipment certainly, as cylinder, solenoid valve etc.
Bracing frame 2 is fixed on the axle head of motor 1, and bracing frame 2 can be a different shape, does circular or semicircle helping and rotates steadily.Thermoelectric Infrared Sensor 3 is fixed on the top of bracing frame 2.Also be provided with left lateral journey switch 4 and right lateral journey switch 5 on the bracing frame 2, lay respectively at the left and right both sides of Thermoelectric Infrared Sensor 3 on the bracing frame 2.
Motor 1 can be direct current generator, alternating current generator or stepper motor etc.Be the work of control motor 1, the control circuit of design runlength switch in electronic circuit, the control circuit of travel switch are accepted start and stop and the forward and backward that the travel switch signal is controlled motor.
The course of work of this pick-up unit is a (see figure 1):
1) at first, motor 1 clockwise rotates, and drives Thermoelectric Infrared Sensor 3 and is moved to the left.
2) when Thermoelectric Infrared Sensor 3 moves to the position of left lateral journey switch 4, when receiving left lateral journey switching signal, electronic circuit sends out stop signal, and motor 1 stops operating.
3) electronic circuit is by the timer time-delay T1 time.
4) after the T1 time delays finished, circuit sent control signal, and starter motor 1 counterclockwise rotates, and drove Thermoelectric Infrared Sensor 3 and moved right.
5) when Thermoelectric Infrared Sensor 3 moves to the position of right lateral journey switch 5, when receiving right lateral journey switching signal, electronic circuit sends out stop signal, and motor 1 stops operating.
6) electronic circuit is by the timer time-delay T1 time.
7) after the T1 time delays finished, circuit sent control signal, and starter motor 1 clockwise rotates, and drove Thermoelectric Infrared Sensor 3 and was moved to the left, so constantly circulation.
Thermoelectric Infrared Sensor 3 is in order to reduce the loss of travel mechanism, to increase life of product moving to the static certain hour of left and right end points.And existing Thermoelectric Infrared Sensor 3 just provides power supply for power saving receiving after there is signal in human body, after detecting less than human body signal, also detect less than human body behind time-delay a period of time T2, just close power supply, so reliability in order to ensure pick-up unit, timer delay time T1 is less than human body that electronic circuit sets time-delay closing supplying time T2 when not existing, otherwise might omission.
In the above-mentioned course of work, Thermoelectric Infrared Sensor 3 moves between the travel switch of the left and right sides, promptly moves with respect to human body 6, thereby has simulated the motion of static human body 6, makes Thermoelectric Infrared Sensor 3 can detect static human body 6.In order all to respond to well in whole intervals of pick-up unit, it is approximate consistent with the minute surface radian of Fresnel lens 7 that the rotational trajectory of Thermoelectric Infrared Sensor 3 keeps.
It is pointed out that 2 of motor 1 and bracing frames can be provided with reduction gear, select with convenient design and parts.Travel switch can detect the device that Thermoelectric Infrared Sensor 3 moves into place for contact switch or photoelectric sensor switch or other.Also travel switch can be set, directly control alternately rotating and reverse of motor by cpu control circuit.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
