Description
Affiliated technical field
The utility model relates to a kind of street lamp control system, and its function is to change the light intensity of regulating street lamp automatically with environmental light intensity.
Background technology
At present the street lamp control system that adopts all is giving of centralized control street lamp: a certain particular moment of every day street lamp control system give electricity, throw light on thereby control street lamp.But the deficiency of this control mode maximum can not be controlled the light intensity of street lamp exactly flexibly.For example, when running into the rainy weather on daytime, this street lamp control system in time start-up control street lamp provides illumination.
Summary of the invention
In order to overcome the deficiency that the transitional street lamps system can not automatically adjust light strength, the utility model provides a kind of road lamp system, and this street lamp control system can be controlled light intensity bright dark of street lamp according to the intensity variations of environment.
The technical scheme that its technical problem that solves the utility model adopts is: utilize phototriode that environmental light intensity is gathered, convert ambient light signal to analog electrical signal, handle through amplification filtering, the analog digital conversion is sent into and is carried out data processing in the single-chip microcomputer, and output digital signal, pass through digital-to-analogue conversion again, the light intensity of control street lamp.Like this, run into daytime during rainy weather,, just can control the light intensity of street lamp, to reach the purpose of flexible control street lamp light intensity because phototriode can be collected light intensity in time and send into single-chip microcomputer and handle.
The beneficial effects of the utility model are, by external environment condition light intensity control street lamp light intensity, adopt single-chip microcomputer in the circuit, accurately handle, and simple in structure, cost is lower.

Embodiment
In figure one, collect ambient light signal by phototriode, by the preliminary amplifying signal of differential amplifier circuit.
At figure two, among the figure three, send into signal by 1,2, through the further amplifying signal of high resistant differential amplifier circuit, once more, signal is sent in the low pass filter of figure three by 3, and by 4 output signals.
In figure four, by 4 signal is input in the analog/digital converter, make analog signal conversion become digital signal and input in the single-chip microcomputer, handle by specific program, and send among the figure eight by bus 5,6.
In figure eight,,, thereby digital signal is converted to analog signal, the light intensity of control street lamp by 5 input Single-chip Controlling digital-to-analogue conversion signals by 6 input data.
Claims (2)
1. a street lamp control system is characterized in that, by signal acquisition circuit, the amplification filtering circuit, analog-to-digital conversion circuit, single-chip microcomputer treatment circuit, D/A conversion circuit is formed in proper order, and ambient light signal is by the phototriode collection, and street lamp is controlled by D/A conversion circuit.
2. street lamp control system according to claim 1 is characterized in that, preserves the program of regulating the street lamp light intensity in single-chip microcomputer.
