Abstract

The utility model discloses a lighting circuit controller which comprises a single chip microcomputer. The single chip microcomputer is orderly connected with a light operated electronic switch circuit, an infrared detection and receiving circuit, and a street light wire control circuit. The lighting circuit controller can automatically turn off lights by day and turn on lights by night through utilizing the operation of the single chip microcomputer and the control of the light operated electronic switch. An infrared transmitting and receiving device is used for detection, and the single chip microcomputer is used for recording time and number and judging walking direction. Street lights are turned on and turned off according to pedestrian walking direction and the condition that whether pedestrians are available the streets or not, so a large quantity of power is saved. The working time of the lights is relatively reduced, and the service life of the lights is accordingly extended.

Description

The lighting circuit controller

Technical field

The utility model relates to a kind of device of controlling lighting circuit, specifically a kind of lighting circuit controller that utilizes single-chip microcomputer and light-operated switch control illumination.

Background technology

Present stage is adopted time control in the little sub-district intraoral illumination system of the density of population more, and this way to manage makes street lamp continuous illumination whole night, causes the huge waste of electric energy, has shortened the useful life of light fixture simultaneously.Illuminator in resident's corridor adopts sound control circuit mostly in addition, and this control mode has influenced resident's studying and living to a certain extent.

The content of utility model

The technical problems to be solved in the utility model is big at the prior art waste of energy, light fixture short deficiency in useful life, the operation of a kind of use Single-chip Controlling operation whole system is provided, utilizes light-controlled electronic switch control illuminator, realize that street lamp cuts out night and connect daytime completely, save the lighting circuit controller of electric energy, light fixture long service life.

Solve the problems of the technologies described above by the following technical solutions: a kind of lighting circuit controller, comprise single-chip microcomputer, described single-chip microcomputer is connected with light-controlled electronic switching circuit, infrared detection and receiving circuit, streetlight control circuit successively.

Adopt technique scheme, compared with prior art, the utility model utilizes single-chip microcomputer operation operation, and the control of light-controlled electronic switch can realize day putting out bright automatic control at night.Adopt infrared emission and receiving system to detect, utilize single-chip microcomputer to come timing, counting and direction of travel to judge, realization has or not with direction of travel according to the pedestrian connects the street lamp of needs illumination and closes the street lamp that need not throw light on.Thereby can save a large amount of electric energy.Because the opening time of illuminating lamp reduces relatively, and then has prolonged the useful life of lighting, and installation cost low (being about 250 yuan), the 3150-10285 unit of can reducing expenses.This installs remarkable in economical benefits, and social benefit is good.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

See Fig. 1, a kind of lighting circuit controller comprises following a few part: light-controlled electronic switching circuit, infrared detection and receiving circuit, streetlight control circuit, Single-chip Controlling unit.Light-controlled electronic switching circuit, infrared detection and receiving circuit, streetlight control circuit are connected with the Single-chip Controlling unit respectively.

See Fig. 2, the light-controlled electronic switching circuit is made up of resistance R 1, photodiode D1, and resistance R 1 is connected in series with photodiode D1 and forms the light-controlled electronic switching circuit, is connected with the P0.0 interface of single-chip microcomputer 8051.Its operation principle is: on daytime, natural lighting intensity is big, photodiode D1 conducting, and the signal of input single-chip microcomputer 8051 is a low level.Single-chip microcomputer 8051 control street lamps quit work; At dusk, when intensity of illumination dropped to a certain degree, photodiode D1 ended, and the signal of input single-chip microcomputer is a high level.Single-chip microcomputer is according to this signal controlling street lamp work.

Infrared detection and receiving circuit are made up of infrared photodiode D2 and resistance R 2.Infrared photodiode D2 and resistance R 2 are connected in series and form infrared detection and receiving circuit, are connected with the P0.1 interface of single-chip microcomputer.The Infrared that the optoelectronic switch reflector sends directly enters infrared detection and receiving circuit, and when object to be detected passed through between infrared detection and the receiving circuit and blocks light, receiving circuit produced switching signal.During nobody process infrared detecting device, receiving circuit is subjected to infrared excitation, infrared photodiode D2 conducting, and the signal of input single-chip microcomputer is a low level, the Single-chip Controlling streetlight control circuit quits work; Through out-of-date, the infrared ray of directive infrared detection and receiving circuit is blocked by human body as the people, and infrared photodiode D2 ends, and the signal of input single-chip microcomputer becomes high level, and single-chip microcomputer is according to the corresponding street lamp work of this signal controlling.

Streetlight control circuit is made up of NAND gate circuit, photoelectrical coupler, street lamp connecting circuit, and photoelectrical coupler adopts MOC3021, and its input is connected with resistance R 3, is connected with the output of NAND gate circuit.The input of NAND gate circuit is connected with the P1.0 interface of single-chip microcomputer 8051.The output of photoelectrical coupler is connected with the street lamp connecting circuit, the street lamp connecting circuit is made up of relay J, street lamp L, and relay J one end is connected with photoelectrical coupler, and the other end is connected with street lamp L, relay J, street lamp L connect the 220V alternating current, form the street lamp link circuit.

When single-chip microcomputer 8051 delivery outlet P1.0 output high level, become low level through behind the photoelectrical coupler, make the photoelectrical coupler conducting after the photoelectricity coupling, to input to consequent circuit low level, at this moment relay J is charged, its coil of adhesive, thus connect street lamp L.

The control mode of Single-chip Controlling unit such as Fig. 3: street lamp of a Single-chip Controlling.

Its course of work is as follows:

When the P0.0 of single-chip microcomputer mouth receive light-controlled electronic switch input connect or disconnect signal the time, call corresponding startup, the program that quits work, thereby the control street lamp connects or disconnects completely.When system is in the Energy Saving Control state, single-chip microcomputer is according to the having of the detected pedestrian of infrared detecting device, nothing and direction of travel, state and the decision of pedestrian's quantity are carried out the numeration program and are controlled the program that street lamp is connected, disconnected, needing to realize the street lamp of illumination to connect the automatic control that the street lamp that need not throw light on disconnects.
