If the humidity is lower than the threshold, a control signal is generated and transmitted to the execution unit to start irrigation; The image processing layer uses image recognition and positioning functions. This layer is responsible for analyzing the images collected by the camera, determining the location of the flowers, using edge detection or color segmentation to determine the shape and position of the flowers, and passing its coordinate data to the drive control unit; The data fusion layer is responsible for fusing the data from multiple sensors to generate comprehensive irrigation decisions.

[0022] Specifically, the humidity sensor interface: This interface is used to connect the soil moisture sensor to collect the moisture data of the flower soil in real time. Through the ADC (analog-to-digital converter), the analog signal output by the humidity sensor can be converted into a digital signal that can be processed by the microcontroller processor, ensuring that the data can be processed accurately.

[0023] Ambient temperature and humidity sensor interface: This interface connects the ambient temperature sensor and the ambient humidity sensor to collect the temperature and humidity information of the surrounding environment. The acquisition of ambient temperature and humidity data can not only determine the watering needs of flowers, but also help optimize the watering plan. For example, when the ambient humidity is high, the amount of watering can be reduced to save water resources.

[0024] Image acquisition interface: The system is equipped with image recognition function. The image acquisition interface can be connected to a camera (such as OV7670 camera) to obtain image information of flowers and convert the image signal into a data format for the microcontroller to perform image analysis and position recognition processing.

[0025] Humidity data processing layer: This layer is used to process the data collected by the soil moisture sensor and compare the current humidity with the preset humidity threshold. If the humidity is lower than the set threshold, the system will generate a control signal and pass the signal to the execution unit to start the irrigation process.

The rotating shaft of the second steering gear (6) is connected to the first end of the first pipe member (7). The third steering gear (9) is installed at the second end of the first pipe member (7). The rotating shaft of the third steering gear (9) is connected to the second end of the second pipe member (8). The first end of the second pipe member (8) is a free end. The hose is inserted into the first end of the first pipe member (7) and exits from the second end. Then, it is inserted into the second end of the second pipe member (8) and exits from the first end.

8. A method for automatic watering of household flowers, characterized in that: The household flower automatic watering system according to any one of claims 1 to 7 comprises the following steps: S1. Environmental monitoring The humidity sensor in the environmental monitoring device continuously monitors the humidity of the flower soil. When the humidity is detected to be lower than the set threshold, the sensor transmits a signal to the microcontroller processor; S2, microcontroller response After receiving the signal of insufficient humidity, the microcontroller starts the watering process: S201, selecting a watering position: using a camera to identify the position of the flower, or determining a specific watering position based on manually marked position data; S202, adjusting the steering gear: adjusting the angle of the watering device by controlling the steering gear 1 (2) so that the watering device is directed toward the flowers; S203, drive module starts: Servo 1 (2) adjusts the rotation angle of the entire device so that the water outlet can be aimed at the target flower; Servo 2 (6) and servo 3 (9) are responsible for adjusting the height of the water outlet so that the water can directly reach the roots of the plants; S204, watering operation: When the water outlet reaches the predetermined position, the microcontroller sends a signal to activate the water pump or solenoid valve; Water pump mode: The water pump draws water from the water storage device and delivers the water to the outlet for irrigation; Solenoid valve mode: open the solenoid valve and use gravity to let the water flow and reach the flowers; Based on the real-time monitoring of soil moisture, the microcontroller will control the opening and closing of the water pump or solenoid valve; S3, watering completion and adjustment: After watering is completed, the microcontroller controls the servo to restore the water outlet to the default position and turn off the water pump or solenoid valve; and records the relevant data in the EEPROM or SD card.
