Technical field
The utility model is related to lighting area more particularly to a kind of self-test infrared inductors.
Background technology
Existing pyroelectric infrared-sensing device can not detect infrared thermal signal when main device damages, when someone passes through
When, pyroelectric infrared-sensing device can not be triggered, leads to the users such as the lamps and lanterns that the rear of pyroelectric infrared-sensing device connected
Electric appliance can not work normally.
Such as mounted on underground garage sensing lamp in nobody lamps and lanterns be not work or half bright state (plays energy saving work
With), if at this moment, inductor, which has damaged, cannot just detect someone's process, the lamp installed there just can not work normally, lamp
It is just constantly in and does not work or half bright state, bring inconvenience to user.
Utility model content
The utility model provides a kind of self-test infrared inductor, by placing an inspection in the front position of pyroelectricity probe
Measuring resistance periodically sends a signal to detection resistance to simulate triggering pyroelectricity probe, will be unable to when pyroelectricity probe is damaged by
Triggering or feedback signal, the purpose is to detect whether infrared inductor damages, information is sent out with not ad hoc fashion in time, so as to and
When lamps and lanterns are repaired, prevent inductor from damaging and bring inconvenience to user.The utility model is suitable for lighting area.
Technical solution is used by the utility model：
A kind of self-test infrared inductor, includes circuit board, on circuit boards equipped with MCU, signal amplification module and infrared
Induction module, the MCU are connected and are controlled the operation of consumer electronics, and the infrared induction module includes a pyroelectricity probe,
It is characterized in that：Selftest module is additionally provided on the circuit board, the selftest module includes the detection electricity of a simulation human body temperature
Resistance, the detection resistance are fixed on the front of pyroelectricity probe induction end；The outside of the pyroelectricity probe is equipped with probing shell,
The probing shell both sides, which are equipped with, to be exceeded pyroelectricity probe and detection resistance is fixed on to the convex block in front of pyroelectricity probe.
More preferably, a kind of self-test infrared inductor, it is characterized in that：The MCU controls selftest module is periodically to detection resistance
Signal is sent to simulate triggering pyroelectricity probe, the temperature signal of pyroelectricity probe sensing detection resistance simulation will simultaneously detect
Signal feeds back to MCU after the amplification of signal amplification module, and the MCU is according to whether receive feedback signal to judge that pyroelectricity is visited
Whether head damages.
More preferably, a kind of self-test infrared inductor, it is characterized in that：The MCU is after selftest module is triggered, it is impossible to receive
During the signal of pyroelectricity probe feedback, MCU controls consumer electronics continuous service or is run according to pre-set programs.
This programme periodically sends a signal to detection electricity by placing a detection resistance in the front position of pyroelectricity probe
Triggering pyroelectricity probe is simulated in resistance, when pyroelectricity probe damage will be unable to be triggered or feedback signal, is detected so as to reach
The effect whether infrared inductor damages allows user that can find failure in time, effectively prevents inductor and damages to making
User brings inconvenience.
Description of the drawings
The utility model is further described below with reference to the drawings and specific embodiments:
Fig. 1 is the device figure of the utility model；
Fig. 2 is the schematic diagram of the utility model.
Figure label is shown：
1-MCU, 2- signal amplification module, 3- infrared induction modules, 31- pyroelectricity probes, 4- consumer electronics, 5- self-test moulds
Block, 51- detection resistances, 6- circuit boards, 7- probing shells.
Specific embodiment：
The utility model provides a kind of self-test infrared inductor, suitable for lighting area.The utility model can be by as follows
Mode is implemented：
As shown in Figs. 1-2：A kind of self-test infrared inductor, includes circuit board 6, and MCU1, signal are equipped on circuit board 6
Amplification module 2 and infrared induction module 3, the MCU1 are the microcontroller of entire inductor operation in order to control, and MCU1 is connected and controlled
The operation of consumer electronics 4 processed；The signal that the signal amplification module 2 includes amplification 3 feedback signals of infrared induction module is put
Big device；
The infrared induction module 3 includes a pyroelectricity probe 31；Selftest module 5, institute are additionally provided on the circuit board 6
The detection resistance 51 that selftest module 5 includes a simulation human body temperature is stated, the detection resistance 51 is fixed on pyroelectricity probe 31
The front of induction end.
The outside of the pyroelectricity probe 31 is equipped with probing shell 7, and 7 both sides of probing shell, which are equipped with, exceeds pyroelectricity spy
First 31 and detection resistance 51 is fixed on to the convex block in the front of pyroelectricity probe 31.
The MCU1 controls 5 timing of selftest module to send signal to detection resistance 51 to simulate triggering pyroelectricity probe 31,
Pyroelectricity probe 31 senses the temperature signal that detection resistance 51 is simulated and amplifies the signal detected by signal amplification module 2
After feed back to MCU1, the MCU1 is according to whether receive feedback signal to judge whether pyroelectricity probe 31 is damaged.
The MCU1 is after selftest module 5 is triggered, it is impossible to i.e. inductor when receiving the signal of the feedback of pyroelectricity probe 31
It has been damaged that, MCU1 controls 4 continuous service of consumer electronics or run according to pre-set programs.For example, when consumer electronics 4 are lamp, in advance
If program can control shining for lamp stroboscopic, to remind user's inductor that there are failures.
To sum up, this programme sends letter by placing a detection resistance 51, timing in the front position of pyroelectricity probe 31
Triggering pyroelectricity probe 31 is simulated number to detection resistance 51, will be unable to be triggered when pyroelectricity probe 31 is damaged or feedback letter
Number, so as to achieve the effect that detect whether infrared inductor damages, allow user that can find failure in time, effectively prevent
Inductor is damaged to bring inconvenience to user.
