Embodiment 1

[0024] Embodiment 1 is applied to the solar aeration control system:

[0025] The function of the oxygenation device is to increase the oxygen content of water in various water environments, which is usually achieved by stirring the water surface or directly injecting air into the water with an air pump. No matter whether solar energy is used or not, the current product aeration device is all independent, and is provided with electric energy by a power line or a solar power station. When the oxygen content in the water drops, it needs to be started manually, and solar power stations are located on the shore due to problems such as battery maintenance, large size, and unreasonable structure. For vast waters, it is necessary to deploy a large number of For power cables, work management is complicated, and on the other hand, its cost performance cannot be controlled.

[0026] Such as Figure 4 As shown, using the oxygen increasing device of the control method of the present i...

Embodiment 2

[0030] Embodiment 2 is applied to a soil detection device:

[0031] If the soil environment can be monitored in agricultural production and forestry and other planting industries, it will have an important impact on reducing workload and increasing production. However, because the traditional solution is difficult to solve the power problem, or the cost is high, it is not suitable for low-efficiency agricultural production, but the solution of the present invention has the characteristics of low cost and high long-term working reliability when applied to soil detection.

[0032] In agricultural production, it is impossible to lay power lines on the farmland for a long time. However, using traditional solar energy application power supply technology has problems such as high cost, difficulty in miniaturization and deployment, and maintenance difficulties if replaceable batteries are used. Inability to work for long periods of time.

[0033] Such as Figure 5 As shown, a low...

Abstract

The invention discloses an intermittent working system and an intermittent working control method for a solar energy application system. An energy source system of the intermittent working system absorbs and converts solar energy, and stores the solar energy into an energy storage device by a charging and discharging controller. An electric energy measurement unit measures the remaining electric energy of the energy storage device in real time, and inputs the remaining electric energy into a singlechip controller. The singlechip controller performs an operation according to the measured remaining electric energy and own preset standard definite value or standard interval serving as switching control output, and realizes a control command for the charging and discharging of the charging and discharging controller or the switching on and switching off of an electronic switch. By the system and the method, core conditions for application control are changed from conventional methods such as manual judgment, timing control and the like into intelligent responses given by the singlechip controller according to electric energy capacity in the energy storage device, so the needs of the solar energy application system in the energy storage device are greatly reduced, a system maintenance cycle is prolonged, and the reliability and stability of the solar energy application system are further improved.

Description

technical field [0001] The invention relates to a solar energy application control system, in particular to an intermittent working system for low-cost solar energy application and a control method thereof. Background technique [0002] With the increasing energy consumption in industrial production and life, the energy crisis is irreversibly approaching the world, which makes people pay more attention to the application of solar energy, an inexhaustible renewable energy source, and invest a huge amount of scientific research put in. A variety of solar energy application systems have emerged as the times require. For example, lawn spraying devices realized by solar energy storage; aquarium oxygenation pumps and water pumps; aquaculture oxygenation pumps; various solar ventilation and heat removal devices, etc. [0003] At present when renewable energy such as solar energy is being paid more and more attention, its application level, especially in application control, still...
