Utility model effect
The ultrasonic ranging of pole low energy consumption involved by the utility model, passive sensor integrative sensor, when You Ren sensor sensing district, wake MCU unit up by passive sensor unit and allow ultrasonic ranging cell operation, the distance of test person or height, the method of dormancy and closed condition is again entered after having worked, MCU unit is allowed to enter dormant state at one's leisure, ultrasonic ranging unit is allowed to be in closed condition at one's leisure, make average power consumption only tens or tens uA of whole equipment, extend service time of battery to greatest extent.
Accompanying drawing explanation
Fig. 1 is the ultrasonic ranging of the utility model pole low energy consumption in an embodiment, the structured flowchart of passive sensor integrative sensor; And
Fig. 2 is the ultrasonic ranging of the utility model pole low energy consumption in an embodiment, the structural representation of passive sensor integrative sensor.
Embodiment
Referring to drawings and Examples, the ultrasonic ranging of the pole low energy consumption involved by the utility model, passive sensor integrative sensor are explained in detail.
Fig. 1 is the ultrasonic ranging of the utility model pole low energy consumption in an embodiment, the structural representation of passive sensor integrative sensor.
Fig. 2 is the ultrasonic ranging of the utility model pole low energy consumption in an embodiment, the structural representation of passive sensor integrative sensor.
As depicted in figs. 1 and 2, the ultrasonic ranging of pole low energy consumption, passive sensor integrative sensor have: MCU unit 1, passive sensor unit 2, ultrasonic ranging unit 3, wireless module unit 4 and power supply unit 5.
MCU unit 1 responds to the movement of infrared thermal releasing charge carrier, measures distance or the elevation information of object in real time.
Passive sensor unit 2 is connected with MCU unit 1, and quantity is three, is arranged on the surperficial centre position of sensor.Passive sensor unit 2 adopts the material of high Seebeck coefficient to make the detecting element being of a size of 2*1mm.Two detecting elements are loaded in each detector, and by two detecting elements with opposite polarities in series, to suppress the interference produced because own temperature raises.To be detected by detecting element and the infrared radiation received is transformed into faint voltage signal, amplify backward outer output through the field effect transistor be contained in probe.The infrared ray centre wavelength of human body radiation is 9 ~ 10--um, and the wavelength sensitivity of detecting element almost stable within the scope of 0.2 ~ 20--um is constant.The window that one is equipped with filter glass has been offered at transducer tip, this optical filter is 7 ~ 10--um by the wavelength coverage of light, just in time be suitable for the detection of human infrared radiation, and the infrared ray of other wavelength is absorbed by optical filter, so just define a kind of special passive sensor unit 2 being used as detection human body radiation.
Ultrasonic ranging unit 3 is connected with MCU unit 1, is arranged on the upper surface of sensor.The distance of ultrasonic ranging unit 3 test person or height.
Wireless module unit 4 is connected with MCU unit 1.MCU unit 1 is sensed to obtain the movement of infrared thermal releasing charge carrier by wireless module unit 4, and distance or the elevation information of the object measured in real time send to remote control device.
Power supply unit 5 is connected with MCU unit 1.Power supply unit 5 adopts powered battery, without the need to wiring, and convenient and flexible installation.
Passive sensor unit 2 real-time working, automatically dormant state is entered after MCU unit 1 starts, only open in short-term when passive sensor unit 2 responds to action, then dormant state is kept, ultrasonic ranging unit 3 is only opened after MCU unit 1 is waken up, be in power-off or closed condition At All Other Times, to reduce equipment power dissipation to greatest extent.
Passive sensor unit 2 working current is about several uA, and ultrasonic ranging unit 3 working current about several mA, MCU unit 1 work often works about hundreds of uA, undercurrent 1uA during dormant state.Average power consumption can be down to ten to tens uA, with significant increase battery life by above-mentioned principle of work.
The effect of embodiment and effect
The ultrasonic ranging of pole low energy consumption involved by the present embodiment, passive sensor integrative sensor, when You Ren sensor sensing district, wake MCU unit up by passive sensor unit and allow ultrasonic ranging cell operation, the distance of test person or height, the method of dormancy and closed condition is again entered after having worked, MCU unit is allowed to enter dormant state at one's leisure, ultrasonic ranging unit is allowed to be in closed condition at one's leisure, make average power consumption only tens or tens uA of whole equipment, extend service time of battery to greatest extent.
Above-mentioned embodiment is preferred case of the present utility model, is not used for limiting protection domain of the present utility model.
