Abstract
A district street lamp intelligent management system, is characterized by comprising an illumination testing circuit, composed of a photoresistor and an integrated operational amplifier circuit, an output end of the illumination testing circuit is connected with an input end of an SCM, the output end of the SCM is connected with a switch tube connecting a relay coil, wherein the input end of the switch tube is connected with the output end of the SCM, the output end of the switch tube is connected with the relay coil, an normally open contact of the relay is connected with a power contactor coil, the normally open contact of the power contactor is connected with the input end and output end of firing lines of the district street lamp. The utility model has the beneficial effect of discriminating daylight and darkness through testing illuminance by the illumination testing circuit, and timely opening and shutting the illumination testing circuit street lamp, thereby reaching the effect of convenient management and energy saving, with simple structure and easy popularization.
Description
Technical field
The utility model relates to a kind of road lamp management system, particularly a kind of sub-district street lamp intelligent management system.
Background technology
The street lamp of sub-district is opened and is turn-offed by administrative staff usually.Owing to can not in time open and turn-off, influenced the normal use of street lamp, owing to can not in time open, make troubles for the life of sub-district, owing to can not in time turn-off, even the phenomenon of long life lamp appears out, brought the waste of the energy.
Summary of the invention
The purpose of this utility model provides a kind of sub-district street lamp intelligent management system.
The technical scheme that its technical problem that solves the utility model adopts is: have lighting detecting circuit, lighting detecting circuit is made up of photo resistance and integrated operational amplifier circuit, the output of lighting detecting circuit is connected with the single-chip microcomputer input, the single-chip microcomputer output is connected with the switching tube that is connected relay coil, the input of this switching tube is connected with the single-chip microcomputer output, this output end of switching tube is connected with relay coil, the normally opened contact of relay is connected with the power contactor coil, and the normally opened contact of power contactor connects sub-district street lamp live wire in-out end.
The beneficial effects of the utility model are to detect illuminance by lighting detecting circuit, distinguish daytime and dark, in time open and turn-off illuminating street lamp, reach convenient management and energy-conservation effect, and it is simple in structure, are easy to promote.
Description of drawings
The utility model is described in further detail below by accompanying drawing.
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
Embodiment
Consult Fig. 1.Single-chip microcomputer adopts the PIC12C508 8-bit microcontroller.
Lighting detecting circuit is made up of photo resistance R and integrated operational amplifier circuit AJ, photo resistance R is connected with the input of integrated operational amplifier circuit AJ (embodiment is positive terminal) by diode D, another input termination bias voltage (embodiment is an end of oppisite phase) of integrated operational amplifier circuit AJ.The output of lighting detecting circuit is connected with single-chip microcomputer PIC12C508 input, single-chip microcomputer PIC12C508 output is connected with the switching tube that is connected relay coil, the input of this switching tube is connected with single-chip microcomputer PIC12C508 output, this output end of switching tube is connected with relay coil, the normally opened contact of relay is connected with the power contactor coil, and the normally opened contact of power contactor connects sub-district street lamp live wire in-out end.
Lighting detecting circuit detects illuminance.Under dark state, photo resistance R has high resistance, the input terminal voltage of integrated operational amplifier circuit AJ is almost equal to zero, diode D conducting, and integrated operational amplifier circuit AJ is to single-chip microcomputer PIC 12C508 input output low level, single-chip microcomputer PIC12C508 output output high level, connect the switching tube conducting of relay coil, control relay adhesive, and then the adhesive of control power contactor, the normally opened contact closure of power contactor, sub-district street lamp live wire is communicated with.Otherwise, by day under the illumination state, integrated operational amplifier circuit AJ is to single-chip microcomputer PIC12C508 input output high level, single-chip microcomputer output output low level, the switching tube that connects relay coil ends, and control relay becomes disconnection from adhesive, and power contactor becomes disconnection from adhesive, the normally opened contact of power contactor disconnects sub-district street lamp live wire, thereby realizes the intelligent management of sub-district street lamp.
