Abstract
A continuous service solar battery control device is composed of a mechanical portion and a circuit control portion, wherein, the mechanical portion is composed of a stepper motor and an engaged gear driving device, the stepper motor control circuit is composed of a day and night overturning control signal circuit; signals provided by the signal circuit are a stepper motor impulse signal is output every 0.05-0.2 seconds, and a timing circuit of 8-15 seconds is set up; in addition, the signal of overturning and starting every time(the signal for starting rotation) consists of signals of starting and stoping of the artificial light source. The energy conversion efficiency of the solar battery is improved by tracking the deflection of the sun and the lighting source, in conjunction with the application of a super capacitor charge circuit, light at night can still allow the solar battery to covert and store energy, and the invention has simple structure and easy operation.
Description
Technical field:
The present invention relates to the control device of solar cell working, especially continuous service solar cell control device.
Background technology
Solar cell generally is considered to work when diurnally has sunlight, has maximum operating efficiency this moment certainly, thereby the deflection that also has operation control device to be used for sun-tracing improves energy conversion efficiency, but does not think that obviously solar cell can work double tides.Yet along with the application of ultracapacitor circuit, light still can make solar cell have Conversion of energy and was stored night.Still there is not this design for scheme at present.
Summary of the invention
Main purpose of the present invention is to prolong the operating time of solar panel, thereby improve the gross generation in its 24 hours, with part solve the transformation efficiency that solar battery process exists at present low, require harshness, input-output ratio to cross problems such as height to operational environment.Traditional solar cell phase counterglow fixed-site, night, energy output was zero, also was subjected to the influence of sunshine condition daytime.
Technical scheme of the present invention is: continuous service solar cell control device, device mainly is divided into mechanical part and circuit control section.Mechanical part is that stepping motor and meshed gears transmission device constitute, and stepping motor control circuit is to be made of the control signal circuit that overturns round the clock; Stepping motor control circuit is: the signal that signal circuit provided is that every 0.05-0.2 exports a stepping motor pulse signal second, and is provided with the timing circuit of 8-15 second, as continuing for 10 seconds; In addition, the signal of each upset startup is the signal controlling that " starting rotation " opened and closed by artificial light source.The present invention can be in the rotation that drives under the signal of control circuit about strip solar panel 180 degree, as required and illumination condition control solar panel, makes it in can both be under the existing illumination condition best work of each period.
The invention has the beneficial effects as follows: thus the energy conversion efficiency of following the tracks of the deflection raising solar cell of the sun and lighting source, and cooperate the application of ultracapacitor charging circuit, light still can make solar cell have Conversion of energy and was stored night, and it is of the present invention simple in structure, easy to use.

Embodiment
Overall structure and mode of operation are as shown in Figure 1
Mechanical part:
Stepping motor can be chosen the different statical moments on the various markets, " six lead-in wires " stepping motor of location torque according to for needs.As: 42BYG228 type stepping motor.Rotation precision is 1.8 degree, can comparatively accurately control the angle of rotating according to signal, and can realize clockwise rotating, rotating counterclockwise two kinds of rotation directions; Statical moment (HoldingTorque) is 2000gcm, and location torque (Detent Torque) is 220gcm.Stepping motor and meshed gears transmission device (comprise and adopt 1: the gearbox of 10-20) constitute, generally make the inclined to one side turnback of mechanical transmission mechanism enough meet the application of satisfying solar cell and satisfy existing sunray to meet the condition of work of throwing light on night.
Circuit part:
1, controllor for step-by-step motor
Controllor for step-by-step motor adopts integrated six line stepper motor drivers, has 12 ports.
2, signal circuit
According to the requirement of controllor for step-by-step motor, be pulse signal of output in per 0.1 second if want cell panel Rotate 180 degree, the signal demand that signal circuit provided, continued for 10 seconds; In addition, every adjacent twice rotation institute should provide different just commentaries on classics (+5V)/(0V) signal reverses." starting rotation " can when that is: artificial light source is enabled, be rotated to cell panel towards light source position by the signal controlling of artificial light source; When artificial light source is closed, rotate to towards position of sun.Timing circuit is made of time-base circuit.As shown in Figure 3.
Roughly sequential chart is as follows: Fig. 4 sequential chart is the signal timing diagram of control rotating
When controlling the signal of rotating: just change during high level, reverse during low level
Fig. 5 is the signal timing diagram of control turn signal, turn signal: high level changes, and low level is not changeed, and promptly T1 is the upset period among the figure, and T2 is the static period
Cycle time, T was: T=T1+T2=(Ri+Rii+Riii) * C*ln2
The ratio of T1 and T2 is (Ri+Rii)/(Rii+Riii)
Each comprises 100 small-signals among Fig. 6 in the upset period:
T1′+T2′＝t0＝T1/100＝(R1+R2)*C*ln2。
For the influence of the heating effect (can cause the reduction of solar battery efficiency) that reduces artificial light source, we also will carry out the heat insulation processing of moisture film to solar panel.
