Control of discharge: when sheet machine PIC16F684 the 10th pin by resistance R7 and R47 carry out dividing potential drop solar panels voltage detected lower than 2.5V time, battery 30 start to street lamp according to arrange pattern power.If battery 30 voltage lower than 11.1V, then enters into discharge prevention state.
Pattern set-up mode: the mode of operation that can be arranged street lamp by the button on equipment easily, comprises period and voltage, can be divided into altogether at least three periods and at least three kinds of power selection modes, is preferably set to 5 periods and 5 kinds of power modes.Concrete operations pattern is as follows:
Control panel 20 has three charactrons 202, first Digital sum pipe 202 show working hour, second charactron 202 shows the time of this period lasts, and the 3rd charactron 202 shows the voltage swing of this period output.Such as three charactrons show 2,5,6.5 successively, and represent current street lamp work station the 2nd period, this period will continue 5 hours, and current battery output voltage is 6.5V.
In addition, under light-operated+time control pattern, when normally working, by key-press input signal, charactron 202 will show different working stages, value class and numerical values recited in turn.
Such as, push button successively, what first charactron 202 showed 1,2,3,4,5 represents respectively and was operated in for the first period, the second period, the 3rd period, the 4th period and bright period in morning.
If second charactron 202 shows h, represent that the value type of current display is the hourage of time control, the hourage (0 ~ 9) of operation duration under this stage of digitized representation of now the 3rd charactron 202 display.
If second charactron 202 shows P, represent that the value type of current display is the rank of power output, the performance number (0 ~ 4 exported under this stage of digitized representation of now the 3rd charactron 202 display, 0=0%, 1=25%, 2=50%, 3=75%, 4=100%)
Such as: numeral method 1h2, represent first the period work duration be 2 hours.
Numeral method 1P3, represents that the power of the first period output is 75%.
By above-mentioned setting, in the time that night is different, we can arrange different mode of operations, and such as: in two hours of 18:0020:00, arranging power output is that in four hours of 30%, 20:00-24:00, arranging power output is 90%; In two hours of 00:0002:00, arranging power output is in four hours of 70%, 02:00-06:00, and arranging power output is 60% etc., makes street lamp be in different brightness.The output of power controls to be that logical superpotential output size controls, and when needs export small-power, main control chip 10 controls battery 30 supply voltage to be reduced.By adjustable timing dimming, energy-conserving and environment-protective.
Controller described in the utility model embodiment is voltage increase and current constant type controller, and voltage increase and current constant drives and completes primarily of chip HV9911.The current precision of TB9911 can reach 2%, and efficiency, up to 90%, possesses current constant control, overvoltage protection, short-circuit protection, PWM dimming function able to programme.
Voltage transitions control principle of the present utility model is as follows: this equipment is voltage increase and current constant type, battery 12V/24V boosted one-tenth 32V, and during full power, constant current is 0.9A.That voltage increase and current constant type control chip is selected is TB9911, TB9911 be closed circuit switching mode LED drive IC design, have good transient response for LED current with to pulse-width adjustment light modulation.Be designed to full-load current in the utility model embodiment and be set to 0.9A, continuous current is mainly arranged by two outside resistance, output current I=0.263 (R80*R81)/(R80+R81).The resistance of what R80 and R81 selected here is 0.56 ohmic precision 1%.The PWM light modulation of TB9911 is the 5 pin output pwm signals by single-chip microcomputer, makes outside street lamp be operated in corresponding power rating, thus controls the brightness of street lamp.The voltage of over-voltage protection point is set to VOUT/36 and is less than 1.25V.Output voltage is set to 32V.Wherein inductance needs to select Sendust Cores inductance.
Sun controller for road lamp disclosed in the utility model embodiment, adopt boosting non-isolated structure, peak efficiency can reach 96%, and user can arrange 5 sections of adjustable (or more) timing dimmings, energy-conserving and environment-protective.By gradual change type light modulation, reduce discomfort during light modulation, farthest can save electric energy, and the service life of extension device.
It should be noted that; the foregoing is only preferred embodiment of the present utility model; not thereby limit scope of patent protection of the present utility model, the utility model can also carry out the improvement of materials and structures to the structure of above-mentioned various parts, or adopts technically equivalent ones to replace.Therefore the equivalent structure change that all utilizations description of the present utility model and diagramatic content are done, or directly or indirectly apply to other correlative technology fields and be all in like manner all contained in the scope that the utility model contains.
