The specific embodiment
Embodiment one:
Present embodiment from the solar cell of the motion tracking sun and optical fiber lighting illumination system as shown in Figure 1, comprise sun light tracking sensor 100, follow-up control circuit 101, mechanical driving device 102, general power be the batteries formed of the maintenance-free lead accumulator of solar panel 106, the cover accumulator cell charging and discharging controller 107 of 150W, two 12V50AH 108, a DC12V-AC220V inverter 109, collective optics array 103, pass light optical fiber 104.Wherein, gather sunshine collective optics array 103, drive mechanical driving device 102 that the collective optics array rotates, control mechanical driving device follow-up control circuit 101, to follow-up control circuit transmit the sun light tracking sensor 100 of sunshine position signalling, the biography light optical fiber 104 that receives converge sunlight is formed the sun light tracking collecting transmitters, its concrete structure can repeat no more referring to " lighting equipment of automatic tracking sun " (number of patent application is 99228399).Solar panel 106 be fixedly installed in collective optics array (lens arra) 103 around, its output is connected through the input of charging-discharging controller 107 with batteries 108, the output of batteries 108 connects lighting 111 through accumulator cell charging and discharging controller 107, indoor illumination intensity automatic controller 110 and inverter 109, and the power input of follow-up control circuit links to each other with the output of batteries through the accumulator cell charging and discharging controller.Whole system is installed on the support 112.
The physical circuit of above-mentioned accumulator cell charging and discharging controller 107 as shown in Figure 2, this controller mainly is made of status monitor circuit, anti-error-polarity connection circuit, anti-reverse charging circuit, anti-overcharge circuit, anti-overdischarge circuit.Wherein, resistance R 7, R8, adjustable resistance P1 send into the voltage signal of battery at the sampling discrepancy end of analog-digital converter ADC0809 and chip microprocessor 8751 (carrying the EPROM of 4K), form status monitor circuit (chip microprocessor can also adopt 8744,8397 etc., and analog-digital converter can also adopt 5G14433, AD574 etc.); Diode D2, D4 and D1, D3 are connected on the output and input two ends of charge-discharge circuit respectively, form anti-error-polarity connection circuit and anti-reverse charging circuit; The P1.2 of chip microprocessor 8751 meets the relay J XQ3 of control charging circuit break-make through input inverter IC5-2, photoelectrical coupler IC6-1,1/7 Darlington transistor MC1413, forms anti-overcharge circuit; The P1.1 of chip microprocessor 8751 meets the relay J XQ2 of control discharge circuit break-make through input inverter IC5-3, photoelectrical coupler IC6-2, Darlington transistor 1/7MC1413, forms anti-overdischarge circuit.
During 107 work of accumulator cell charging and discharging controller, the magnitude of voltage of batteries is sampled among the analog-digital converter ADC0809, convert data signal to and send in 8751 by R7, R8, P1.Shown in Fig. 3 accumulator cell charging and discharging controller Automatic Control Theory block diagram, when solar irradiation is mapped to solar cell 106, status monitor circuit in the accumulator cell charging and discharging controller 107 judges at first whether batteries 108 has reached the discharge lower limit 116 of setting, if just sending signal by P1.2, the electric weight deficiency makes relay J XQ2 break contact, stop to discharge 117, to avoid overdischarge; If the electric weight abundance just makes relay J XQ2 adhesive, discharge 118, for follow-up control circuit 101 and lighting provide power supply.Judge whether to need charging 119 then, just send signal by P1.1 and make relay J XQ3 break contact if arrive the charging higher limit of setting, stopping is that it charges 120, overcharges avoiding; Then the electric energy that solar cell 106 produces is charged 121 by the contact of JXQ3 adhesive to it if need charging.The system of present embodiment self power consumption is 10W, calculated in 10 hours by working every day, needing electricity consumption is 0.1KWH, accumulator cell charging and discharging controller 107 is calculated charge value 122 in the batteries 108 at any time according to the status monitoring circuit of inside, just the P1.0 by 8751 sends instruction when available power residue 0.3KWH, relay J XQ1 is discharged, break contact, stop other electrical appliance power supply 123 outside follow-up control circuit 101, so just can guarantee that follow-up control circuit 101 has enough electric weight of work in three days.If strengthen the power of solar panel, it is that various electrical equipment use that native system can provide more electric energy.
Shown in Fig. 1 system principle diagram, sun light tracking sensor 100 sends the position signalling of sunshine to follow-up control circuit 101, follow-up control circuit 101 drives lens arra 103 by mechanical driving device 102 and solar battery array 106 moves to respective direction, make lens arra 103 and solar battery array 106 accurately aim at the sun gradually, by fibre bundle 104 sunshine is transferred to place such as indoor illumination such as 105 grades then.When weather was better, through darg, batteries 108 just can reach maximum accumulation of energy value.When night and rainy weather, batteries 108 can provide electric energy for lighting 111 by accumulator cell charging and discharging controller 107.
Because considering sunshine is not change all the time, all can influence the stable of indoor illumination intensity cloudlike, atmospheric turbulance etc., the vision of giving the people is with uncomfortable sensation, therefore present embodiment also comprises a cover indoor illumination intensity automatic controller 110, its circuit theory mainly is made up of photo-detector 114, illuminance control circuit 115, lighting 111 as shown in Figure 4.Described photo-detector can be photo resistance, photodiode, photosensitive triode or photocell; Described illuminance control circuit comprises operation amplifier circuit, delay circuit and switch control element, and wherein the operation amplifier circuit of present embodiment is made up of LM258, the resistor network (reference voltage is provided) that links to each other with the end of oppisite phase of LM258; Delay circuit mainly is made up of the LM555 timer; The switch control element is controllable silicon, solid-state relay, mechanical relay or photoelectrical coupler.Behind the photo-detector resistance in parallel, link to each other with the in-phase end of operational amplifier, lighting links to each other with the switch control element in the illuminance control circuit.
The operation principle of illumination automatic controller 110 as shown in Figure 5.When the illumination intensity signal value of photo-detector 114 with room light is sent in the illuminance control circuit 115 at any time, operation amplifier circuit is set this signal value with adjustable resistance reference voltage is compared, pass through the judgement of NAND gate and the time-delay of LM555 timer circuit then, be switched on or switched off a certain group of lighting successively, adjust total luminous power of lighting 111.When light intensity surpassed certain value, the luminous power of lighting 111 was 0; When indoor illumination value does not reach requiring of setting, just room light is being compensated in the illuminance control circuit 115 by the luminous power of adjusting lighting 111, make indoor illumination intensity constant, guarantee that room lighting reaches the requirement of setting, make native system practical more.
Present embodiment gets up solar electrical energy generation and optical fiber daylighting reasonable combination, has made full use of its advantage separately, does not consume conventional power supply, and can reach the higher solar energy utilization rate, can wait the place of power shortages to use in the open air.Through evidence, effect is very good.
