Embodiment
Automatically photovoltaic lighting control device is regulated to be described further below in conjunction with the drawings and specific embodiments to the utility model discharge power: as shown in the figure, containing controller, computer monitoring, solar cell, storage battery, inverter, DC lighting system, alternating-current illuminating system in the present embodiment, described controller and computer monitoring are by 485 bus serial ports wiring, and controller is connected respectively by binding post with computer monitoring, solar panel, storage battery, inverter, DC lighting load.
Described controller contains single-chip microcomputer, memory, I/O equipment and communication module.Described inverter is connected with interchange lighting load.The output signal of described solar panel is current signal.
Solar panel output voltage, the detection of electric current.Detect the output voltage that solar panel is different, and according to different voltage, system makes different control treatment.Detect solar panel output electric current measure, make system by certain control algolithm, make system works at maximum power point, and open tracking maximum power point by day, during night, close this function.Lead acid accumulator charge and discharge controls.System is in order to protect storage battery as far as possible, and life-saving, adopts corresponding charge and discharge control strategy according to different capacity.Controller system, realizes control and the scheduling of efficient information processing and each functional module.Computer supervisory control system, by serial ports and controller system real-time, interactive data, supervisory control device system mode.
Accompanying drawing 1 is the photovoltaic lighting system frame diagram of solar cell, and this system is made up of parts such as solar cell, controller, computer monitoring, storage battery, inverter, DC lighting system, alternating-current illuminating systems.Specific works principle: the direct current that solar module produces to be used to DC load by a controller part or delivered to and change into alternating current, and a part is charged to storage battery under the irradiation of sunlight daytime; When sunlight is not enough, storage battery send load to use by DC control system to DC load or through inverter.Controller and computer monitoring are by 485 bus serial ports wiring in addition, thus by serial ports and controller system real-time, interactive data, supervisory control device system mode.
Accompanying drawing 2 is the maximum power tracing main circuit diagram of solar panel, realizes the tracking of maximum power point, controls exactly, the duty ratio of the switching device in regulating circuit with the algorithm of maximum power tracing to DC-DC change-over circuit.The design adopts Buck-Boost circuit realiration MPPT function, and the output of photovoltaic cell group connects the input of One Buck-Boost converter body, and the output of One Buck-Boost converter body is subject to the control of MPPT algorithm, powering load, charge in batteries.
Accompanying drawing 3 is the measurement illuminated circuit diagram of solar cell.When illumination shines on silicon photo diode, it produces weak current, conversion is amplified through I-V two-stage, produce measurable voltage, size is at 0-5V, because the voltage after impinging upon illumination on silicon photo diode and conversion presents approximate linear relationship, so can in advance by regulating lamp illuminance, its illumination at silicon optical sensor is made to be 100Lux, then keep this illumination constant, adjustable resistance R5 is regulated to make the voltage 0.50V of output Out, then keep R5 constant, the illumination of silicon optical sensor is worked as in inspection is successively 200-1000Lx, OUT exports the voltage linear with it at 1V-5V.
Accompanying drawing 4 systems soft ware is divided into lighting controller software and supervising software.Wherein Lighting control mainly comprises: DC-DC controls, maximum power point tracking module, accumulator cell charging and discharging administration module, intelligent dimming module, serial communication module.Control system is according to solar battery array, the operating state of storage battery and load is divided into two kinds of operational modes, charge mode and electric discharge mode of operation, control system according to solar battery array, the operating state automatic switchover operational mode of storage battery and load.
Charge mode: when control system runs on charge mode, single-chip microcomputer has two-way PWM to export, i.e. PWM1, PWM2, is respectively used to control power switch pipe Q1, Q2.Have again following two kinds of situations when system works is in charge mode: 1 solar battery array power output is greater than bearing power, unnecessary electric energy supplies to charge a battery and realizes the MPPT maximum power point tracking of solar battery array; 2 load ports, solar battery array only charges a battery.
