Description

Double-ended night-vision remote-sensing delay-action circuit breaker

The utility model relates to two ends night vision remote sensing delay switch, the two ends night vision remote sensing delay switch of more clearly the say so illumination of public places such as being used for building corridor, corridor, lavatory and warehouse, occasion such as antitheft.

The night vision remote sensing delay switch in past is used for military affairs more, and complex structure, cost are also expensive, are not suitable for civilian occasion.In recent years, country always energy savings as one of important research project.Along with development and national economy, building constructions is more and more, and the illuminating lamp electricity consumption of public place and corridor, corridor is also more and more.For convenience, lamp switch has been installed in these places mostly.But people usually forget these switches of switching.Therefore, these illuminating lamps usually become " altar lamp ", and effective rate of utilization is low, have consumed a large amount of electric power in vain, have caused waste to country.In order to save electric energy, public places such as many corridors, corridor are not installed illuminating lamp without hesitation, and people grope action, and are very inconvenient again.In order not only to throw light on but also economize on electricity, the contact delay switch of light-emitting diode has just appearred having.But this switch also has shortcoming and defect, the one, and terminals are many, and at least three contacts are installed complicated.The 2nd, press just switch but must catch to touch, unhygienic.The 3rd, just delay time is fixing after setting,, then to repeatedly contacts to press and just can as staying the long period in these occasions.In the lavatory of hospital, the contact delay switch becomes all means of infection, endangers very big.

The purpose of this utility model, be to overcome above-mentioned shortcoming and defect, a kind of public place such as corridor, corridor, lavatory and warehouse illumination, occasion such as antitheft of being used for is provided, simple in structure, cost is low, must not touch, hygienic and convenient, the utilance height, energy-saving effect is obvious, the two ends night vision remote sensing delay switch that can control automatically.

In order to achieve the above object, the utility model two ends night vision remote sensing delay switch by housing, be fastened on the lid on the housing and the electronic circuit that is installed in the housing is constituted.Have two holes that can transmit and receive infrared light respectively on the housing.The infrared reception amplifier that electronic circuit is formed by the infrared emission amplifier of forming with elements such as operational amplifier and infrarede emitting diodes, with elements such as two-level operating amplifier and infrared light-emitting diodes, with infrared reception amplifier coupling and have the operational amplifier, driving amplifier of time capacitor C, the relay circuit that drives with driving amplifier is constituted.Two infrared diodes are installed in respectively in two holes on the housing, are convenient to outwards transmitting and receiving of infrared light.The model of infrared diode is 2DF, 2DU.Reality be the photoelectric properties unanimity to the pipe, its stable performance, low price.Four computings are sent out device big and can be sent out device LM747 circuit big by a slice integrated four-operational amplifier LM324 circuit or two integrated pair of computings and constitute, and low price is functional.

The utility model has adopted infrared electronic technology,, receive by the infrared reception amplifier that with infrared light-emitting diode is transducer again and amplify faint infrared ray to outside spatial emission infrared light beam by the infrarede emitting diode of the infrared emission amplifier of optoelectronic integration.Emission constitutes an infrared visual field with reception.In the time of in object enters the visual field, object is with reflected infrared ray.The component that is reflected is received by infrared reception amplifier and amplifies, and detection becomes dc control signal, with the driving relay, thereby realizes on off state.Simultaneously, after object entered the switch visual field, the direct current after the detection was to keeping the capacitor charging, and the capacitor volume size has determined human body to leave the delay time of switch visual field, back with the time of discharging and recharging.The pre-amplifier of infrared reception amplifier adopts direct current to amplify, and infrared light-emitting diode presents low-resistance when ambient brightness surpasses certain value, thereby makes amplifier enter saturation condition.The saturated amplifier generation obstruction that makes is not worked at the bright place of light to guarantee the back level.When ambient brightness was dark, infrared light-emitting diode presented high resistant, makes amplifier enter the linear condition operate as normal.So, just can distinguish the environment of light and shade automatically.In other words, can not work during the utility model light on daytime, could work when having only night or light dark.It is the multivibrator of load with infrarede emitting diode and resistance that the infrared emission amplifier is one actually.Infrared light-emitting diode is an infrared light transducer[sensor actually.

Supply power mode of the present utility model adopts parallel stabilized voltage power supply.In the loop of load and power supply, lighting bulb and a capacitor provide energy for circuit to stabilized voltage power supply by a voltage-stabiliser tube two ends string.In other words, an end of the present utility model gets final product with being connected in parallel on the 220V civil power with the other end after lighting bulb is connected again.The task of the utility model two ends night vision remote sensing delay switch comes to this and finishes.

The utility model has only two terminals, and the mode of connection is the same with regular tap, installs simple and conveniently, has overcome the shortcoming of contact delay switch three terminals in the past.Simultaneously, it has overcome human body contact and manual deficiency, hygienic and convenient.It only when night, dark place human body enter in the field range of this switch switch just move.The people leaves behind the switch visual field switch disconnection of just delaying time.When environment bright when certain certain value, also be failure to actuate even the people enters switch switch the visual field in, thereby reach the effect that makes things convenient for economize on electricity.It can be in the field range of 0.5～2M action message, bright adjustable threshold value, delay time can be adjusted in several seconds～a few kilosecond time ranges.Its quiescent dissipation is little, and a year power consumption has only 0.5～1 degree.Its driving power is big, but the incandescent lamp bulb of load 15～100W.In addition, it is in light weight, health, and cost is low.It can be widely used in public place such as corridor, corridor, lavatory and warehouse illumination, occasion such as antitheft.

Below in conjunction with embodiment and accompanying drawing thereof night vision remote sensing delay switch in the utility model two ends is done further explanation.
