Description of drawings
Fig. 1 is a module frame chart of the present utility model;
Fig. 2 is a unit in kind of the present utility model connection diagram.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult illustrated in figures 1 and 2ly, solar display screen of the present utility model comprises:
Photovoltaic panel array 1, being one another in series by many groups solar cell panel assembly constitutes, and output is connected in intelligent controller 2.Preferential embodiment, described solar cell panel assembly adopt list/polycrystal silicon cell assembly to constitute.Because the output power of solar cell is at random, in the different time, different places, the output power of a same solar cell is different.Closing between solar module output rating and the electrical appliance power input and tying up to the East China approximately is 2-4: 1, and concrete ratio is by requiring decision with electronic display working time every day and to continuous overcast and rainy electricity consumption.The about 120W/m of the output power of solar cell 2The output E-I characteristic of photovoltaic panel array 1 has strong nonlinear, and with meteorological conditions such as solar radiation intensity, environment temperature, wet weather, mists substantial connection is arranged.It is output as with the direct current measurement that changes sunshine, make photovoltaic generating system work that more satisfactory operating mode be arranged, and all to bring into play the maximum potential of photovoltaic panel array 1 output power under current sunshine to any sunshine, this will use an intelligent controller 2, make to reach duty harmonious, efficient stable between battery pack 3 and the electronic display 5.
Intelligent controller 2 comprises a shell, which is provided with Wiring port, is provided with control circuit in it, and input is connected in photovoltaic panel array 1, and the two-way battery pack 3 that is connected in, and output is connected in DC converter 4.Described control circuit comprises a controller circuitry and the overcharge protection circuit, over-discharge protection circuit, short-circuit protection circuit, overload protecting circuit, the tandem PWM charging circuit that are connected thereon.Intelligent controller 2 output is supplied with the required working power of electronic display 5 through DC converter 4.Described intelligent controller 2 is EPHC-EC intelligent controllers, and the control chip of controller circuitry can 51 singlechip chips, its embedded Control Software.
Battery pack 3 is connected in intelligent controller 2.Preferred embodiment, accumulator are 2, and first accumulator 31 and 32 series connection of second accumulator constitute battery pack 3.Control circuit in the intelligent controller 2 of its connection is according to the characteristic of battery pack 3 final discharging voltage curve corrections, control is revised, eliminated the inaccuracy of simple Control of Voltage overdischarge, meet the intrinsic characteristic of battery pack 3, be that different discharge rates has different end of a period voltage, guaranteed that battery pack 3 obtains the most effective use.And connect thereon overcharge protection circuit, over-discharge protection circuit, short-circuit protection circuit, overload protecting circuit, tandem PWM charging circuit guaranteed to have and overcharged, cross put, electrical short, overload protection, etc. full-automatic protection control.Adopt tandem PWM charging main circuit, make the loss of voltage of charge circuit use the charging circuit of diode reduce near half, the more non-PWM of charge efficiency is high by 3%～6%, has increased the electricity consumption time.Cross the lifting charging of putting recovery, directly fill normally, the floating charge automatic control mode makes system that be arranged longer serviceable life; Has temperature compensation accurately simultaneously.Other has intuitively the LED luminotron and indicates current battery pack 3 duties, and the user is come into plain view.The controller circuitry of intelligent controller 2 can closed when system makes a mistake automatically, security and reliability when the assurance system moves.
For battery pack 3 its pool-sizes are physical quantitys of an outbalance, because the intake of solar photovoltaic generation system is extremely unstable, so generally need the configuration battery system to work.The choice of capacity of battery pack 3 directly influences the reliability and the system price of system.The choice of capacity of battery pack 3 generally will be followed following principle: at first can satisfy under the prerequisite of using night, the energy of solar module stores as far as possible on daytime, also wants simultaneously to store the electric energy that satisfies continuous overcast and rainy night lighting needs.The too small needs that can not satisfy night lighting of the capacity of battery pack 3, the capacity of battery pack 3 is excessive, and battery pack 3 is in the power shortage state all the time on the one hand, influences the life-span of battery pack 3, causes waste simultaneously.
DC converter 4, input is connected in intelligent controller 2, and output is connected in electronic display 5; Described DC converter 4 is exported the Control of Voltage of battery pack 3 to the driving DC voltage of electronic display 5.
Electronic display 5 comprises a shell and is arranged at its interior display control circuit, demonstration storage unit and display panel module that input is connected in DC converter 4.The shell of described electronic display 5 is a hermetically-sealed construction, on it and be provided with antidetonation and swing protection member and heat conduction member.Electronic display 5 adopts the outdoor pixel pipe of PH10mm display design, and real image is plain to show that the beam split color separation is better, and the color saturation height, for whole luminous, color is even, literal clear display, exquisiteness, true to nature all have big visible angle in level with vertical, can realize the single-point maintenance.The screen tube core uses and is positive wave long tube core, and strict emission wavelength with each LED display is controlled in the 5nm; Provide LED true to nature, complete, high-quality to show that screen image resolution, sharpness are very high to literal, screen text is clear not to glimmer.The screen body form to adopt the body structure of splicing flexibly, and shell is hermetically-sealed construction, it on and be provided with antidetonation and swing protection member and heat conduction member, satisfies protection against the tide, anticorrosion, prevents travel fatigue, the requirement of high temperature resistant, electrostatic prevention, fire protection flame retarding, antidetonation.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
