A solar cell panel is respectively connected with a storage battery and an inverter through a charging and discharging controller; the inverter is connected with a priority output terminal; the priority output terminal is connected with an electric appliance; the storage battery is respectively connected with an ampere meter and a voltage meter; the ampere meter and the voltage meter are connected with an input signal processing circuit; the input signal processing circuit is connected with an AT89S52 singlechip; the AT89S52 singlechip is connected with an output control circuit; and the output control circuit is connected with the priority output terminal. The solar power management system has the technical effects that an automatic processing control device is combined with a software control program, various electric appliances are arranged in different priorities according to the importance of the electric appliances in specific occasions, and the electric quantity of solar photovoltaic power generation is distributed; and moreover, and the electric quantity judgment is realized by judging the current, voltage or electric power in the system.
Description
Technical field
The allocation manager system is carried out in the use that the present invention relates to a kind of electric weight that solar energy power generating is produced.
Background technology
Because solar energy power generating receives solar irradiation time and weather condition restriction; Solar power system generally has energy storage device; When not generating electricity very much is that electrical appliance provides electric power, and the electric weight that stores in this case is limited, and the use of electrical appliance is restricted; The solar power system that adopts is not at present classified by the significance level of demand to electrical appliance, or disposable electric weight is used up, and all electrical appliances are all stopped using, and have so also influenced other basic electricity demands, like the night illumination demand etc.How the use to limited electric weight is optimized, be the solar energy generation technology development the problem that will face.
Summary of the invention
The purpose of this invention is to provide a kind of solar electric power management system.
Technical scheme of the present invention is, a kind of solar electric power management system, and solar panel connects accumulator and inverter respectively through charging-discharging controller; Inverter connects the priority lead-out terminal, and the priority lead-out terminal connects electrical appliance; Accumulator connects reometer and voltage table respectively, and reometer and voltage table connect the input signal treatment circuit, and the input signal treatment circuit connects the AT89S52 single-chip microcomputer, and the AT89S52 single-chip microcomputer connects output control circuit, and output control circuit connects the priority lead-out terminal.
The present invention has following technique effect; Adopt automatic processing controls device to combine software control procedure; The significance level difference of in the specific occasion, using according to various electrical appliances is arranged in different priority, and the use of solar energy power generating electric weight is distributed; The judgement of electric weight is to realize through the judgement to the electric current in the system, voltage or electric power.Automatically processing controller comprises: signals collecting input block, output control unit, software control procedures such as chip processing unit, current/voltage.The control principle of software control procedure is: under solar electrical energy generation amount condition of limited, progressively stop power supply according to the ordering that electric weight changes according to priority from low to high from big to small; To inserting this management system but the electrical appliance that does not meet this system's electrical quantity designing requirement stop power supply.
Description of drawings
Fig. 1 is a circuit block diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of solar electric power management system is characterized in that: solar panel connects accumulator and inverter respectively through charging-discharging controller; Inverter connects the priority lead-out terminal, and the priority lead-out terminal connects electrical appliance; Accumulator connects reometer and voltage table respectively, and reometer and voltage table connect the input signal treatment circuit, and the input signal treatment circuit connects the AT89S52 single-chip microcomputer, and the AT89S52 single-chip microcomputer connects output control circuit, and output control circuit connects the priority lead-out terminal.
Automatically processing controller comprises: signals collecting input block, output control unit, software control procedures such as AT89S52 single-chip microcomputer processing unit, current/voltage.Signals collecting input blocks such as current/voltage are through the measure electric weight of voltage measuring apparatus to the voltage of accumulator in the solar power system; Electric weight use respectively from big to small Q0, Q1, Q2 ... Qn representes, through current measuring device the electric current in the using electricity system is measured current value I.Output control unit is provided with several output control terminal mouths, represents different priority respectively, and priority is represented with P0, P1, P2...Pn from high to low.
The control principle of software control procedure is: under solar electrical energy generation amount condition of limited, progressively stop power supply according to the ordering that electric weight changes according to priority from low to high from big to small, table 1 is the concern correspondence table of electric weight Q with priority P.The electrical appliance of judging connecting system whether compliance with system designing requirement is to be worth In according to current value I with the current ratio of setting in the software to compare, and when I >=In duration T, stops this electrical appliance power supply.
Table 1: electric weight Q is with priority P output relation correspondence table
| Electric weight Q | Priority P |
| Q0 | P0、P1、P2...Pn |
| Q1 | P0、P1...Pn-1 |
| ... | ... |
| Qn-1 | P0、P1 |
