FPGA-based solar automatic watering device

technical field

The utility model belongs to the technical field of solar energy and relates to a flower watering device, in particular to a solar automatic flower watering device based on FPGA.

Background technique

With the improvement of the quality of life, more and more families like to plant potted plants. Due to the fast-paced urban life, people often forget to water the potted plants, causing the potted plants to die due to lack of water. At the same time, overwatering some dry plants can cause the plants to die.

Contents of the invention

The purpose of the utility model is to provide a solar automatic watering device based on FPGA, which can not only water potted plants in time, but also prevent excessive watering.

In order to achieve the above object, the technical solution adopted by the utility model is: a solar automatic flower watering device based on FPGA, including a water tank and a control device, and the control device adopts FPGA; a water level sensor is installed on the water tank; the water outlet of the water tank communicates with the water pump , the water outlet of the water pump is connected with multiple electric valves; the number of soil temperature and humidity sensors is the same as the number of electric valves; the water pump and multiple electric valves are connected with the relay control circuit, and the control device is respectively connected with the relay control circuit, water level sensor, Solar cells and multiple soil temperature and humidity sensors are connected.

The automatic flower watering device of the utility model adopts a soil temperature and humidity sensor to detect the real-time humidity of the flower soil, and waters when the humidity is less than a set minimum threshold value. FPGA intelligently controls the water pump by controlling the relay control circuit to realize automatic intelligent watering. For different flowers, different humidity thresholds are set to prevent improper watering from causing flowers to die. Solar energy is used to provide electric energy, so that the flower watering device does not need an external power supply, thereby saving energy.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the automatic flower watering device of the present utility model comprises water tank 1 and control device 4, and control device 4 adopts FPGA; The soil temperature and humidity sensor 10 is connected, the solar cell 2 is connected with the storage battery 3; the water level sensor 8 is installed on the water tank 1, and the water level sensor 8 is connected with the control device 4 signal; the water outlet of the water tank 1 is connected with the water pump 7, and the outlet of the water pump 7 The water port communicates with a plurality of electric valves 6; the number of buttons 9, the number of soil temperature and humidity sensors 10 and the number of electric valves 6 are the same. The water pump 7 and the plurality of electric valves 6 are all connected to the relay control circuit 5 , and the relay control circuit 5 is connected to the control device 4 .

Soil temperature and humidity sensor 10 adopts SLHT5-1 digital temperature and humidity sensor.

LCD display 11 adopts LCD1206 liquid crystal display.

When using the automatic flower watering device of the present utility model: inject clear water in the water tank 1, embed a soil temperature and humidity sensor 10 in the soil of each potted plant that needs automatic watering, and place an electric sensor 10 on each potted plant that needs automatic watering at the same time. valve 6. Control the potted variety of automatic watering according to needs and set the humidity threshold and the watering time of this potting soil in the control device 4, set the watering time by FPGA to realize quantitative watering. The soil temperature and humidity sensor 10 collects the humidity value of the potting soil in real time, and transmits the humidity value to the control device 4. When the humidity value of the potting soil detected by the soil temperature and humidity sensor 10 in a certain potting soil is less than the set humidity When the threshold is reached, the control device 4 sends a signal to start the water pump 7 and the electric valve 10 placed on the potted plant through the relay control circuit 5 for watering. Control circuit 5 closes water pump 7 and this electric valve 10, stops watering.

When the flower grower wants to determine whether a specific potted plant needs to be watered, the potted plant can be selected by button 9. At this time, the soil temperature and humidity sensor 10 in the potted plant transmits the humidity value of the potted plant soil to the control device 4, and the control device 4. Send the humidity value to the LCD display 11 for display. If the potted plants need to be watered, the control device 4 sends a signal to start the water pump 7 and the electric valve 10 placed on the potted plants through the relay control circuit 5 to water, and when the watering time reaches the set watering time, the control device 4 sends a signal to close the water pump 7 and the electric valve 10 through the relay control circuit 5, and stop watering.

During the flower watering process, when the water level sensor 8 detects that there is no water in the water tank 1, the water level sensor 8 sends a signal to the control device 4, and the control device 4 closes the water pump 7 and the electric valve 6 that is discharging water through the relay control circuit 5, and cuts off the automatic valve 6. Watering circuit, stop watering flowers.

When the sunlight is sufficient, the solar cell 2 generates electric energy to provide power to the entire system and to charge the storage battery 3. At this time, the storage battery 3 does not supply power to the system. When the solar cell 2 does not generate electric energy, the storage battery 3 supplies power to the system.
