Abstract
The utility model discloses a kind of charging current value that utilizes to judge intensity of illumination and then street lamp to be carried out to the illumination induced intelligent solar street light of light on and off operation, it is characterized in that comprising solar panels, rechargeable battery, A/D converter, microcontroller and street lamp five part, the charging current change utilizing the induction of the solar panels of solar street light to intensity of illumination itself to cause judges outdoor brightness, Dominating paths lamp on/off, without the need to artificial change control time or additional sensing device.
Description
Technical field
The utility model relates to a kind of solar street light, especially can judge intensity of illumination and outdoor brightness according to charging current, the intelligent solar road lamp of automatic light on and off.
Background technology
At present, the known solar street light light on and off time all controls with single-chip microcomputer timing controlled or photo resistance voltage dividing bias circuit.Single-chip microcomputer timing controlled is the time being set bright light by single-chip microcomputer timer and turned off the light, when the operation that the time then just carries out bright light or turns off the light.Photo resistance voltage dividing bias circuit is the voltage being changed bleeder circuit by the change in resistance of photo resistance, realizes the light on and off controlling street lamp.But the defect of employing timing control method for making is the different time in a year, Various Seasonal, the time of daybreak and darkness can change, and often need the time of artificial amendment setting, and photo resistance voltage dividing bias circuit control methods utilizes external sensor part, integrated level is low, and cost is higher.
Summary of the invention
In order to overcome the deficiency that existing solar street light control method often needs artificial modification time and utilizes external sensor part, the utility model provides a kind of new control method, this control methods utilize solar street light self solar panels to illumination respond to cause charging current change judge outdoor brightness, automatically light or extinguish street lamp.
The know-why that the utility model solves its technical problem is: solar street light is charged by its solar panels to internal cell and store electricity with coming to street lamp power supply, road lamp power supply, in charging process, charging current changes with the change of intensity of illumination, we can judge outdoor brightness according to the value of charging current, thus control the light on and off of street lamp.Can there be the lumen parameter of standard in each solar panels producer when solar panels dispatch from the factory, the i.e. relation of intensity of illumination and electric current, a value X is set according to this value, add an A/D converter at charging circuit and measure charging current value, and be converted to digital value A, compare with set point X, as A >=X, represent that outdoor is brighter, street lamp extinguishes; As A<X, represent that outdoor is comparatively dark, street lamp is lighted.
Technical solutions of the utility model are specially: a kind of solar street light, and it comprises solar panels, rechargeable battery, A/D converter, microcontroller and street lamp five part; Solar panels are connected with rechargeable battery, and connect an A/D converter between solar panels and rechargeable battery, A/D converter is connected to microcontroller, and microcontroller controls street lamp; A/D converter between solar panels and rechargeable battery for detecting the size of charging current, and converts current value to digital value; The current digital value that A/D converter detects passes to microcontroller, by the result comparing value and the programmed values detected, microcontroller judges that street lamp should be lighted or extinguish, and then sends instruction Dominating paths lamp on/off.
The beneficial effects of the utility model are, outdoor brightness is divided in the solar panels induction zone that can be carried by solar street light, and realize the Based Intelligent Control to solar street light light on and off, do not need to adopt outside sensing element, integrated level is high, with low cost.
Accompanying drawing explanation
Fig. 1 is know-why schematic diagram of the present utility model;
In figure: 1-solar panels, 2-rechargeable battery, 3-A/D converter, 4-microcontroller, 5-street lamp.
Embodiment
In FIG, solar panels (1) receive illumination and carry out opto-electronic conversion and charge to rechargeable battery (2), battery (2) provides operating voltage for circuit (3,4) and street lamp (5), and charging circuit adds an A/D converter (3), measure charging current value, and current value is converted to digital quantity A and passes to microcontroller (4), this value and set point X compare by microcontroller (4), as A >=X, represent that outdoor is brighter, street lamp extinguishes; As A<X, represent that outdoor is comparatively dark, street lamp is lighted.
Claims (3)
1. a solar street light, it comprises solar panels, rechargeable battery, A/D converter, microcontroller and street lamp five part, it is characterized in that solar panels are connected with rechargeable battery, connects an A/D converter between solar panels and rechargeable battery; A/D converter, can detect the size of charging current, and convert current value to digital value; A/D converter is connected to microcontroller, and microcontroller controls street lamp.
2. solar street light according to claim 1, is characterized in that, the current digital value that A/D converter detects passes to microcontroller, compares with the set point in program.
