The street lamp of corridor control at present is mainly sound-controlled apparatus, and its shortcoming is to need the people to applaud, and shouts or firmly pedal that the floor sends that the sound of certain decibel could trigger sound-controlled apparatus and the Switching Power Supply of connecting street lamp makes it luminous.The place of monitoring with camera system, general video camera all is to work incessantly, in fact do not need shooting sometimes, if by human inductor control camera system of the present utility model, start camera system in the time of can be in the people comes across induction range, be compared to the former and obviously have advantage.
The utility model content
The purpose of this utility model, promptly providing a kind of human inductor, can launch stable electromagnetic wave, as the static body, when entering this electromagnetic zone as human body, this stable electrical magnetic wave is subjected to the disturbance of static electricity on human body field, this inductor is sensed this disturbance, and other device of being attached thereto of start signal output, as lights a lamp, alarm, or camera system.
For achieving the above object, the utility model is provided with a high-frequency oscillating circuits, and it sends stable electromagnetic wave, and induction static body, when sensing the static body, and its conducting warning device; One regulator rectifier circuit, it comprises rectifier, filter and pressurizer are converted to power for illumination the working power of high-frequency oscillating circuits; One power unit, the deferent segment of its pressurizer is connected to high-frequency oscillating circuits, thus it provides power supply; One low-pass amplifier, it receives the output of radio-frequency generator and with its amplification; One floated comparator, its reception exports delay circuit to through the low-pass amplifier amplifying signal and with comparative result; One delay circuit, it is connected to the pickup time of relay with control relay.The utility model also comprises light-operated circuit, its output is connected to power supply, thereby the control power supply determines to the high-frequency oscillating circuits power supply whether high-frequency oscillating circuits works, and this light-operated circuit contains photo resistance, resistance is by its suffered intensity of illumination decision, thus the break-make of decision power supply.Wherein radio-frequency generator comprises by the transistor that has antenna, inductance, and electric capacity and resistance are formed, and antenna is connected to transistor drain, and this antenna launching electromagnetic wave receives the electromagnetic wave that is subjected to the disturbance of static body, and it is fed back to radio-frequency generator.The input of low-pass amplifier of the present utility model is connected to the output of described radio-frequency generator, and its output signal is amplified.The input of floated comparator of the present utility model is connected to the output of low-pass amplifier.Delay circuit of the present utility model receives the comparator output signal through broadening output, and delay circuit has manual delay function.Thereby the power supply of realizing automatic sensing and conducting miscellaneous equipment makes its work.
Use the utility model and can control coupled equipment automatically, thereby be implemented in when needing its work, its unit switch of conducting makes its work, turn-off its power supply when not needing its work, power saving and need not manpower control, its novelty and other characteristics can cooperate the following drawings and DETAILED DESCRIPTION OF THE PREFERRED and clearly be understood.
Description of drawings:
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is a detailed circuit diagram of the present utility model.
Embodiment
At first see also accompanying drawing 1, operation principle of the present utility model is that the electromagnetic wave that radio-frequency generator produces is launched through antenna, in the time of in static bodies such as human body appear at this electromagnetic space, antenna feeds back to radio-frequency generator with the electromagnetic distu of induction, radio-frequency generator outputs signal to low-pass amplifier, signal after amplifying is sent to floated comparator, and the comparative result of comparator is input to delay circuit after broadening output, drive relay then and the power turn-on of controlling miscellaneous equipment whether.
In an embodiment of the present utility model, please refer to accompanying drawing 2, human inductor comprises voltage stabilizing rectification circuit, high-frequency oscillating circuits.Wherein in the voltage stabilizing rectification circuit, the civil power of input by the bridge rectifier rectification, exports the power circuit part to through filtering and voltage stabilizing then after capacitor C 9 and resistance R 22 step-downs.The power unit circuit further with voltage drop to 12 volts and through pressurizer, as three terminal regulator 7812, to the high-frequency oscillating circuits supply power.The output of high-frequency generator is input to low pass amplifying circuit ICD after dividing half that is depressed into supply voltage through resistance R 7 and R8, its low frequency signal to high-frequency generator output amplifies and compares, and the interference of the signal of elimination 50Hz, it outputs signal to floated comparator.Antenna is not sensed the static body in high-frequency generator, during as human body, 7 pin of comparator 1CB are output as high level, the 8 pin output low levels of comparator 1CC, and when induction static body, 7 pin output low levels, 8 pin output high level triggers BG3 conducting in the power supply, makes the luminous or startup warning device of electric light, and after the people leaves, turn-off the power supply of electric light or warning device.
In some place, in the certain hour section, as daytime, do not need this inductor work, and need this inductor work in the other period, this can be realized by another embodiment of the present utility model, can be in series with photo resistance RD on the base stage of transistor BG5 in power circuit, during daytime, the resistance of photo resistance RD is very little, not conducting of BG5, the entire circuit non-transformer can not trigger work, after darkness, it is big that the resistance of photo resistance RD becomes, the BG5 conducting makes relay J K1 conducting, thereby to the high-frequency oscillating circuits power supply, high-frequency oscillating circuits is being sensed the static body, during as human body, 7 pin of comparator 1CB are output as high level, the 8 pin output low levels of comparator 1CC, and when induction static body, 7 pin output low levels, 8 pin output high level triggers BG3 conducting in the power supply, makes the luminous or startup warning device of electric light, and after the people leaves, turn-off the power supply of electric light or warning device.
