Abstract
An intelligent solar energy amber flashing light in low power consumption, a control circuit of the amber flashing light is formed by a microcomputer control chip PIC16F676 as the core; the amber flashing light is driven to work by the pulse width modulation (PWM) control waveform which is changed by a control procedure in the microcomputer control chip automatically, on one hand, the luminous brightness of a LED in the amber flashing light is strengthened in the daytime, and the luminous brightness of the LED in the amber flashing light is reduced at night, on the other hand, when the terminal voltage of a battery has a falling trend, the luminous brightness of the LED in the amber flashing light is also reduced progressively, and when the terminal voltage of the battery continues falling, the control procedure changes the flash frequency of the amber flashing light automatically and progressively so as to utilize the electric energy rationally and lengthen the continuous working capacity of the amber flashing light at the rainy day effectively.
Description
Affiliated technical field
The utility model relates to a kind of intelligent low-power consumption solar energy brown flasher, adopting microcomputerized control chip PIC16F676 is the control circuit that core is formed brown flasher, drive brown flasher work with pulse-width modulation (PWM) control waveform, electric weight situation according to ambient light brightness and storage battery, automatically change the luminosity and the flicker frequency of brown flasher by the control program in the microcomputerized control chip, reasonably utilize electric energy thereby reach, further strengthen the overcast and rainy continuous firing ability of brown flasher.
Background technology
General common solar energy brown flasher has only a kind of fixing working method, i.e. luminosity and the fixing flicker frequency work of brown flasher under the normal situation of accumulator electric-quantity to fix, in order to strengthen the overcast and rainy continuous firing ability of brown flasher, can only increase the configuration of power-supply system or the luminosity of reduction lamp, the result one who brings like this is the increase of cost, the 2nd, the visual degradation of brown flasher, especially poorer in the stronger effect on daytime of ambient light.
Summary of the invention
In order to adjust the operating state of brown flasher automatically according to the electric weight situation of ambient light brightness and storage battery, reasonably utilize electric energy, under the prerequisite that does not reduce performance, further strengthen the overcast and rainy continuous firing ability of brown flasher.The utility model provides a kind of intelligent low-power consumption solar energy brown flasher, the main microcomputerized control chip PIC16F676 that adopts is the control circuit that core is formed brown flasher, drive brown flasher work with pulse-width modulation (PWM) control waveform, electric weight situation according to ambient light brightness and storage battery, automatically change the luminosity and the flicker frequency of brown flasher by the control program in the microcomputerized control chip, circuit structure is simple, and working stability is reliable.
The technical scheme that the utility model adopted is: with a microcomputerized control chip PIC16F676 is the control circuit that core is formed brown flasher, detect entering apparatus with a photoelectrical coupler (U3) as ambient light, its input is connected on the outlet line of solar module, its output inserts the input port (RA4) of PIC16F676, with two groups of series resistance (R13, R14 and R15, R16) be connected on storage battery two and bring in the change conditions that detects accumulator voltage and two input port (RC0 that are linked into PIC16F676 respectively, RC1), the position of each input port of PIC16F676 end can be changed by its inner control program.Under different ambient lights, different magnitudes of voltage can appear in the RA4 port of PIC16F676, when detecting at RA4 when being daytime, the output of PIC16F676 will the bigger pwm control signal of output duty cycle make the LED average current in the brown flasher increase, and the luminosity of the brown flasher lamp panel of being made up of a plurality of LED will strengthen; When detecting at RA4 when being night, the output of PIC16F676 will make the LED average current in the brown flasher slow down little by the less pwm control signal of output duty cycle, the luminosity of LED lamp panel will reduce, simultaneously, on another input port RC0 of PIC16F676, the voltage detection signal of storage battery is by this port input, when downward trend that the terminal voltage that detects storage battery occurs, the pwm control signal that PIC16F676 will progressively adjust output makes the LED average current in the brown flasher slow down little, the terminal voltage of storage battery continues the downward trend of appearance after PWM control is adjusted to designed minimum value, at this moment, PIC16F676 will begin progressively to adjust the intermittent time of the pwm control signal of output, thereby reduces the flicker frequency of brown flasher; After battery tension recovered normally, brown flasher can be adjusted to the operating state of acquiescence automatically.The RC1 port of PIC16F676 is used for detecting the under-voltage and overpressure situation of storage battery.
The beneficial effects of the utility model are, can and not increase the overcast and rainy continuous firing ability that can further strengthen brown flasher under the prerequisite of system configuration at the overall performance that does not reduce brown flasher.
The general hardware circuit time to street lamp that is easy to realize is controlled, and does not need the software programming of complicated specialty, and making and maintenance are easier to, and circuit structure is simple, and working stability is reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is circuit theory diagrams of the present utility model.
Among the figure: U1: microcomputerized control chip PIC16F676, U2: circuit of three-terminal voltage-stabilizing integrated, U3, U4: photoelectrical coupler, T1:NPN type triode, T2, T3:N channel field-effect triode, BAT: storage battery, LED: be light-emitting diode, LEDS: lamp panel, D0～D4: diode, C1～C5: electric capacity, R1～R21 are resistance, and PV+, PV-are the solar module input port.
Specifically execute mode
In the drawings, U1 is microcomputerized control chip PIC16F676, mainly finish charging control to storage battery, brightness adjustment control and discharge prevention function, on its port RA4, connecting photoelectrical coupler U3 by resistance R 4, port RC0, RC1 is respectively by resistance R 15, R16 and R13, R14 is connected the two ends of storage battery, charging control signal removes to control T3 after the output of RA5 port is isolated by photoelectrical coupler U4, dimming control signal and discharge prevention signal remove to control T1 from the output of RC2 port, T2 is connecting the luminous lamp panel of the brown flasher of being made up of several light-emitting diodes on the source electrode of T2; RA2 is the function of temperature compensation control port, variations injunction temperature by sampling diode D3 is carried out temperature-compensating, RC3 and RC4 are directly connected to LED1 and LED2 as the output port of operating state indication, other of PIC16F676 all do not connect on the power supply VSS by resistance with port, and the terminal voltage of storage battery is by the U2 conversion and stablize+be added in the vdd terminal of PIC16F676 for its work behind the 5V.The input of photoelectrical coupler U3 is connected on PV+ and the PV-by current-limiting resistance R6, by day, during the solar module normal power generation, the input of photoelectrical coupler U3 just has electric current and flows through, and output can become low level, at night, when solar module can not normal power generation, the input of photoelectrical coupler U3 does not have electric current, and output can become high level, and PIC16F676 changes the waveform of adjusting dimming control signal by the level that detects the RA4 port.On port RC0, connecting resistance R 15 and R16, after the voltage of storage battery has change, by after R15 and the R16 sampling dividing potential drop information that changes being sent among the PIC16F676 by the RC0 port, deciding the brightness adjustment control waveform by the program of PIC16F676 inside.On port RC1, connecting the under-voltage and overvoltage that resistance R 13 and R14 are used for detecting storage battery.The position of each port can redefine by programming in the circuit.
