Regarding the solar panel 10 (such as a solar photovoltaic panel), it is used to convert sunlight energy into electrical energy.

The energy storage device 20 is electrically connected to the solar panel 10 to store the electric energy converted by the solar panel 10.

The water storage device 30 is a water storage tank or a water storage tank, which is used to store water and discharge water for irrigation.

In this example, the energy storage device 20 is a supercapacitor, and the pumping device 40 is a submersible motor; among them, the submersible motor is an energy-consuming device. Generally, the electric energy converted by the solar panel cannot directly make it run. Therefore, The present invention stores the electric energy converted by the solar panel 10 in a super capacitor. According to the characteristics of easy energy storage and extremely low output internal resistance of the super capacitor, a large current submersible motor can be started smoothly. The design can reduce the volume of the solar panel 10, has the advantages of easy installation and lower installation cost, effectively improves the performance and can operate even when the environment is low light; in design, the first pipeline 41 of the pumping device 40 is also There is a check valve 412; the check valve 411 can prevent the water in the first pipeline 41 from flowing back to the pumping device 40, and can continue to store water when pumping again.

When the voltage value of the energy storage device 20 is greater than the first voltage condition value, the voltage comparator 21 outputs a start signal to the microcontroller 50 so that the microcontroller 50 controls the switch S1 of the energy storage device 20 Is turned on to supply power and start the pumping device 40 for pumping; when the voltage value of the energy storage device 20 is less than the second voltage condition value, the voltage comparator 21 outputs a stop signal to the microcontroller 50 to make the The microcontroller 50 controls the switch S1 of the energy storage device 20 to close, thereby stopping the power supply and stopping the pumping device 40; when the water level reaches the preset position of the water level switch S2, the microcontroller 50 controls the pumping device 40 stops working; and when the environmental information sensed by the sensing device 60 meets the irrigation condition value, the microcontroller 50 controls the first outlet valve 31 or the third outlet valve 421 to open, and irrigates according to the preset The length of time to discharge water.

In more detail, the sensing device 60 can be a light sensor or a humidity sensor. The light sensor is used to sense the illuminance of the surrounding environment, and the humidity sensor is used to sense the soil moisture value.

Assume that the present invention has two sensing devices 60, namely a light humidity sensor and a light sensor, and the irrigation condition value of the microcontroller 50 includes a humidity condition value and a light condition value, and the humidity The condition value is set to 50, and the light condition value is 1000; and the related process embodiments of water storage, energy storage, irrigation, etc. of the present invention are described as follows:

As shown in Figure 2, which is the water storage and energy storage irrigation flow chart of the present invention, the process steps are as follows:

First set the initial value of the irrigation time T;

Then, the soil moisture is sensed by the sensing device 60;

Then the microcontroller 50 determines whether it is daytime; if it is not during the day, close the valves (the first, second, and third outlet valves, 31, 411, 421) and the switch S1, and the microcontroller 50 Enter sleep mode; if it is daytime, compare whether the sensed soil moisture value M is less than the set humidity condition value;

If the soil moisture value M is less than the set humidity condition value (default is 50), the irrigation mode will be carried out according to the set irrigation time T length (T=0 means the time is up, stop irrigation and switch to water storage mode), Stop irrigation or return to soil moisture sensing when the voltage is low;

If the soil moisture value M is greater than the set humidity condition value, it means that there is no need for irrigation and the water tower storage mode (that is, the water source is pumped to the water storage device 30 for storage); and when the water level is full, the energy storage The device 20 stops power supply and switches to a charging mode (energy storage), and stops charging after it is fully charged.

As shown in Figure 3, it is the charging mode flow chart of the present invention. First, detect the battery (the energy storage device 20) voltage V (V=0~4.2v), and then determine whether the voltage V is less than 4.2v, if so , The switch S1 is turned on and charging is performed; if not, the switch S1 is turned off and charging is stopped.

As shown in Figure 4, it is the flow chart of the irrigation mode of the present invention. First, the light sensor is used to detect the sunlight illuminance L (L=0~100000lx), and the irrigation time T is set to 20; if the illuminance L is greater than 1000 , The switch S1 and the third outlet valve 421 are controlled to open, and irrigation is performed according to the set irrigation time length (when there is sunlight, the water is directly supplied by the pumping device 40), and the third outlet valve 421 is closed when the time is reached; If L is less than 1000, the first outlet valve 31 is controlled to open and the water is discharged from the water storage device 30, and the irrigation is performed according to the set irrigation time length (there is no sunlight directly supplied by the water storage device 30), and the water is closed when the time is up First outlet valve 31.

As shown in Figure 5, it is the flow chart of the water storage mode of the present invention. First, the light sensor is used to detect the sunlight illuminance L (L=0~100000Lx). If the illuminance L is greater than 1000, the switch S1 and The The second water outlet valve 411 enables the pumping device 40 to pump the water source to the water storage device 30 for storage (there is sunlight to store water), until the full water level is reached (the water level switch S2 preset position is reached), the switch is closed S1 and the second outlet valve 411 stop water storage; if the illuminance L is less than 1000, the switch S1 and the second outlet valve 411 are controlled to be closed, and no water storage is performed.

Of course, the above process settings for water storage, energy storage, and irrigation are just examples; in practice, users can also change their settings according to different needs; of course, when there is insufficient light and water is urgently needed, users can also By self-operation, the energy storage device 20 is powered to start the water pumping device 40 to pump water, or the first water outlet valve 31 is directly opened and the water storage device 30 supplies water for irrigation.

Based on the above detailed description, those who are familiar with this technique can understand that the present invention can indeed achieve the aforementioned objects, and that it has actually complied with the provisions of the Patent Law.
