Embodiment
The utility model is to the deficiency of solar energy application system traditional control method, and innovation has proposed a kind of novel application controls mode.This control mode realizes based on the service intermittent system.
Analyze from principle, break through the restriction of traditional control method, the utility model is with energy resource system and the total system of application system integration for being controlled by an electric energy measurement unit and singlechip controller.Specifically as shown in Figure 2: this service intermittent system is provided with an electric energy measurement unit on energy storage device; Measure the electric energy surplus of energy storage device in real time; And the output of electric energy measurement unit is connected with a singlechip controller; The control output end of this singlechip controller links to each other with switching circuit with the input of charging-discharging controller, and the break-make control of the switching command and the switching circuit of charging-discharging controller is provided.As shown in Figure 2, the power storage of solar components PV conversion is in energy storage device, and controller changes the directly work of control application component through detecting the energy storage device electric energy stored.When the energy storage device electric energy stored reaches between singlechip controller preset a standard definite value or standard regions; Controller output makes that charging-discharging controller discharges, second control command of electronic switch closes; The work of control application component, along with the work of application component, the energy storage device electric energy stored is consumed; When below the standard definite value that reaches setting or outside between standard regions; Controller first control command that output makes charging-discharging controller charging, electronic switch disconnection according to operation result, the control application component quits work, and energy storage device continues charging.Repeat this process repeatedly, to reach application target.As shown in Figure 3, be the energy curve of this solar energy application system energy storage device.
The utility model has thoroughly changed the application controls mode of solar energy source system or other regenerative resource, changes the core condition of application controls into by the decision of the power capacity in the energy storage device new controlled condition by conventional methods such as artificial judgment, timing controlled.And change Just because of this, the configuration needs account form of energy storage device thoroughly changes in the application system.Usually the energy storage device of some related application systems disposes three to five times that need reach solar energy energy output every day usually.Owing to consider cost performance, use lead acid accumulator usually, and its cycle life has only on average about 500 times, improved use cost greatly.Because the lead-acid battery volume is bigger, the structure optimization of application system is restricted simultaneously.And change at the configuration requirement of the utility model energy storage device: the energy storage device energy storage capacity satisfies application component short time continuous firing demand at least.
Thereby, adopt the configuration requirement of energy storage device behind the utility model will reduce to one of the percentage of conventional method even lower.Under this configuration condition; System can adopt expensive but the better novel battery of performance; For example lithium iron battery, super capacitor or high power capacity electrochemical capacitor or the like, the cost of system and performance will be significantly improved, particularly through using heavy-duty battery; Can significantly prolong the maintenance period of battery, thereby reduce cost of use.
What is worth mentioning is that energy storage device is as the temporary parts of energy, through the electric energy of short time storage solar energy converting; When reaching certain reserves; Just start application component work, in the shorter time, the energy of being stored is discharged, accomplish application function.In operating time, condition etc. not being forced the application demand that limits, the control method of the utility model can reduce the overall cost that adopts solar energy and other regenerative resource power supply significantly, increases substantially efficiency, reduces use cost.
Embodiment one is applied to solar energy oxygenation control system:
The function of oxygen-increasing device is to improve the oxygen content of water in the various water environments, adopts the water surface to stir usually or directly uses air pump mode of injection air in the water to realize.No matter whether adopt solar energy, present product oxygen-increasing device all is independently, to it electric energy is provided through power circuit or solar power station.When the oxygen content in the water descends; Need manually start its work; Problems such as battery service, volume are big, unreasonable structure all are located at the bank and solar power station is because it exists, and for wide waters, need to lay a large amount of electric power cables; Work management is complicated, and its cost performance also can't be controlled on the other hand.
As shown in Figure 4, the oxygen-increasing device of use the utility model control method can be realized the continuous oxygen supply to water body.At fine day; Under the sufficient situation of illumination, the air pump operating frequency is higher, and under the more weak situation of illumination such as overcast and rainy and early morning, dusk; The operating frequency of air pump is lower; But, always can work, and no longer need Artificial Control through the accumulation booster air pump of a period of time as long as solar components can be converted to electric energy.
In this example, what preset in the singlechip controller is between standard regions, and measured electric energy surplus is lower than following the prescribing a time limit between standard regions; The energy storage device charging; Motor-driven as application component quits work, and measured electric energy surplus is higher than going up in limited time between standard regions, energy storage device discharge; Motor-driven starts and operation, is depleted to until the electric energy surplus to be lower than lower limit between standard regions.
Owing to need to drive powerful parts---air pump, adopted to have the bigger super capacitor of specific power as energy storage component, because it has high cycle life, long-term work does not need to change.
Simultaneously structurally, because the energy storage device configuration significantly reduces, volume greatly reduces, and can realize the integrated of solar components, control system, pump, energy storage device.Through the special control method of the utility model, can realize the unmanned operation of complete unattended duty, it is very convenient that a large amount of layings are applied to water field of big area.
Embodiment two is applied to soil testing assemblies:
Plant husbandry such as agricultural production and forestry is if can monitor soil environment, to alleviating workload, improving output and have material impact.But because traditional scheme is difficult to solve power issue, perhaps cost is higher, is not suitable for the agricultural production of poor benefit, and the utility model scheme is applied to soil and detects that to have a cost low, the characteristics that reliable long-term working property is high.
In agricultural production, can't extended immobilization lay power circuit in the farmland, and use traditional Application of Solar Energy power supply technique; Exist cost high, be difficult to problems such as miniaturization laying, popularization, and if use removable battery; Exist again difficult in maintenance, can't long-term work etc. problem.
As shown in Figure 5, adopted a small-power solar components in this example, energy storage device uses a jumbo electrochemical capacitor (also can be the less super capacitor of capacity).What preset in the singlechip controller is the standard definite value, when measured electric energy surplus is lower than the standard definite value, and the energy storage device charging, application component decommissions; And when measured electric energy surplus is higher than the standard definite value, the energy storage device discharge, the application component running is lower than the standard definite value once more until the electric energy surplus.Because the continuity of soil monitoring is less demanding; Therefore through a low power solar cell, through long-time (in hour) charging, wait for be full of energy storage component after; Controller promptly begins to be transducer and sample circuit power supply; Gather and translation data, send to host computer through communication module after accomplishing, thereby accomplish the sampling process of a Monitoring Data.
This instance can the implemented with low cost soil monitoring, can according to different environment for use characteristics configuration different power, satisfy the needed electric energy of communication of different distance and pattern in the plant husbandry widespread adoption, can be applied to various plant husbandry application.
Except that above-mentioned two embodiment, the novel application of the utility model method of possibly effecting a radical cure also may be implemented under other multiple applied environment, for example: the lawn sprayer unit; Aquarium oxygen increasing pump, water pump; The used for aquiculture oxygen increasing pump; Agricultural; All kinds of solar energy ventilation heat releases or the like.
