Abstract

The invention belongs to the field of power supply systems and discloses a power supply system which comprises a solar cell, a control circuit, a photosensitive resistor, a storage cell, a mains supply, a power supply circuit and an advertising board. The power supply system is characterized in that the solar cell, the storage cell and the mains supply are connected with the control circuit, the mains supply, the storage cell and the advertising board are connected with the power supply circuit, a single chip microcomputer is arranged in the control circuit, the photosensitive resistor is arranged on the control circuit, and a storage cell charging management chip is arrange don the power supply circuit. Through a charging control circuit applied to a grid-connected LED environment-friendly advertising board power supply system, a control system has functions of time control and reverse charging resisting; the power supply system aims at intelligently charging a lead acid storage cell, so that the circumstance that service life is quickly reduced due to overcharging and over-discharging of the lead acid storage cell, and energy resources are fully utilized. The power supply system is simple in structure and easy to popularize.

Description

A kind of electric power system
Technical field
The invention belongs to electric power system field, particularly relate to a kind of electric power system.
Background technology
Along with constantly giving prominence to of energy crisis, the utilization for new forms of energy more carrys out rate and significantly promotes.Photovoltaic lighting apparatus, by feat of energy-saving and environmental protection, feature easy for installation, establishes critical role in illuminating industry.In recent years, along with constantly improving and development of commercialization, advertisement career also does larger and larger, and the energy is dropped on advertisement career more and more many.Based on environmental protection and energy saving theory, You Duo company produces solar billboard in the market, but these billboards generally do not fully take into account how to make storage battery energy transfer ratio problem in maximum and useful life.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of effective energy storage and the electric power system rationally transformed.
A kind of electric power system, comprises solar cell, control circuit, photo resistance, storage battery, civil power, power supply circuits and billboard; It is characterized in that described solar cell, storage battery is all connected with control circuit with civil power; Civil power, storage battery are all connected with power supply circuits with billboard; Wherein be provided with single-chip microcomputer in control circuit; Bright resistance is arranged on control circuit; Power supply circuits are provided with charge in batteries managing chip.
A kind of electric power system of the present invention, what it is characterized in that described storage battery adopts is lead acid accumulator.
A kind of electric power system of the present invention, is characterized in that the supply power voltage of described billboard is 15V.
A kind of electric power system of the present invention, is characterized in that described billboard adopts LED to be light emitting source.
A kind of electric power system of the present invention, is characterized in that described battery management chip is CN173.
A kind of electric power system of the present invention, by being applied to the charging control circuit of parallel net type LED environment protection advertisement board electric power system, control system possesses time control, anti-reverse charging, for Lead-acid Battery Intelligent Charging, making lead acid accumulator not because overcharging, crossing and put and reduce rapidly useful life, making the energy be fully used simultaneously.Electric power system structure of the present invention is simple and be easy to promote.
Accompanying drawing explanation
Fig. 1 is structural schematic block diagram of the present invention.
Embodiment
A kind of electric power system, comprises solar cell, control circuit, photo resistance, storage battery, civil power, power supply circuits and billboard; It is characterized in that described solar cell, storage battery is all connected with control circuit with civil power; Civil power, storage battery are all connected with power supply circuits with billboard; Wherein be provided with single-chip microcomputer in control circuit; Bright resistance is arranged on control circuit; Power supply circuits are provided with charge in batteries managing chip.
A kind of electric power system of the present invention, what described storage battery adopted is lead acid accumulator, and lead acid accumulator is used for energy storage, for LED billboard.The supply power voltage of described billboard is 15V.Described billboard adopts LED to be light emitting source, and it is low, high than same power modulation brightness that it has voltage, energy-conservation feature.Described battery management chip is CN173.Solar panel is the energy main source of parallel net type LED environment protection advertisement board electric power system, and effect is that solar energy is converted into electric energy, is stored in lead acid accumulator.Control circuit controls the charging stage of lead acid accumulator, realizes the trickle to battery, constant current, overcharge, floating charge pattern, and control storage battery and civil power are to the electric power thus supplied of LED billboard simultaneously.The use of photo resistance, photo resistance in order to absorb light better, structure of generally laminating, the larger resistance value of intensity of light is less, and on the contrary, more small resistance value is larger for the intensity of light, and photo resistance is at high temperature, still can reliablely and stablely work under the adverse circumstances such as many wet.Start-up time for lead acid battery charge does not need accurate control, only relies on sunlight intensity and determines, and with low cost, is applicable to solar charging electric management system.Under the control of charging Control management system, solar components daytime is to 12V lead acid battery charge, evening, lead acid accumulator provided electric power to LED advertising lamp, when overcast and rainy or other situations cause lead acid accumulator cannot store enough energy continuously, civil power can be used as accessory power supply and powers to LED billboard.
