TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent gardening and small-scale agricultural irrigation, in particular to a multi-mode intelligent potted plant watering method and system. BACKGROUND

[0002] The potted plant intelligent waterer is an automatic watering device specially designed for potted plants. It can monitor humidity, temperature, season and time in real time through intelligent sensors, and automatically adjust watering frequency, water volume and watering time according to the actual water demand of plants, to ensure that the potted plants get the right amount of water supply. This intelligent waterer not only saves the trouble of manual watering, but also effectively avoids the problem of plant wilting or root rot caused by improper watering, greatly improving the convenience and scientific nature of potted plant maintenance.

[0003] The maintenance of potted plants or small-scale garden crops has high requirements for watering time, water volume and frequency. The household watering equipment on the market usually has three defects: First, watering through a certain structure or timer can easily lead to excessive or insufficient watering; Second, relying on a single soil humidity sensor cannot obtain the watering characteristics of plant types, and the soil sensor is prone to failure, which can also lead to excessive or insufficient watering; Third, lacking the ability to perceive and decide seasonal, light intensity and environmental factors, it cannot achieve precise watering strategy by choosing time and amount, which leads to the need for frequent user intervention, insufficient automation and intelligence, and difficulty in achieving "intelligent and unmanned" maintenance.

[0004] Therefore, a multi-mode intelligent potted plant watering method and system are designed, which has multiple modes, can integrate multiple environmental information, has sensor fault tolerance function, and can intelligently adapt to seasons and select plant types. SUMMARY

[0008] Preferably, when the target watering mode is a constant humidity mode, step S3 specifically comprises: S34: Comparing the real-time collected soil humidity with the preset humidity opening threshold and the humidity closing threshold; S35: If the soil humidity is lower than the preset humidity opening threshold, a control instruction for starting the watering operation is generated; S36: If the soil humidity reaches or is higher than the preset humidity closing threshold, a control instruction for stopping the watering operation is generated.

[0009] Preferably, the abnormal fault tolerance process in step S5 is specifically: when it is determined that the soil humidity sensor data is abnormal, the current watering mode is automatically switched to the timing mode, and a prompt information is sent through the man-machine interaction interface.

[0010] Preferably, the way to determine that the soil humidity sensor data is abnormal is: in the constant humidity mode or the intelligent mode, the single watering duration exceeds the preset safe duration, and the soil humidity data does not change as expected.

[0029] S3033: Condition judgment and instruction generation, the system combines real-time data to judge: whether it is the recommended period? Is the current humidity lower than the target range? Is the UV intensity up to the trigger condition? According to the judgment result, accurate instructions to open / close the irrigation nozzle or atomization nozzle are generated.
