Embodiment Construction

[0057] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0058] like figure 1 As shown, the irrigation system consists of camera 5, sprinkler irrigation pump 2, mobile nozzle 7, hose reel 3, buffer water tank 1, ultrasonic seedling height measuring probe 10, Raspberry Pi main control unit 4, 4G network module 6, cloud server 8, APP 9 composition. The water demand status of the seedling tray and the coverage rate of the seedlings are calculated and completed by the camera 5 and the main control unit 4 of the Raspberry Pi. The weather forecast information is obtained through a 4G network module 6, and the data request of the cloud server 8 is responded to, and the field data is real-time Pass to cloud server 8. The precise irrigation of seedlings is completed by mobile nozzles 7, each group of mobile nozzles 7 can serve an area of ​​5m, and each group of hose reels 3 can support 25m of linear moveme...

Abstract

The invention discloses a fuzzy control irrigation method for rice seedling raising in hard land. The method comprises the following steps of: calculating the evapotranspiration of seedlings; carrying out fuzzy double-coefficient evapotranspiration calculation on the seedlings by considering a basic crop coefficient and a soil evaporation coefficient; monitoring the growth state of seedlings through a camera carried by an unmanned aerial vehicle, and adopting a movable sprinkling irrigation head to achieve precise irrigation of seedling trays. The sprinkling irrigation system is composed of a camera, a sprinkling irrigation pump, a fixed nozzle, a main control unit, a 4G network module, a cloud server and an APP. The paste logic fully considers the evapotranspiration effect of crop moisture, the evapotranspiration required by a seedling tray on the day is estimated through illumination, humidity, atmospheric pressure and temperature values of 24-hour weather forecast and seven-stage fuzzification, and then the basic irrigation amount is formed through correction of a fuzzification double-crop coefficient method. According to the invention, low-cost precise drip irrigation is realized, and the method has wide application prospect and feasible practical value.

Description

technical field [0001] The invention relates to garden gardening sprinkling irrigation devices, in particular to a fuzzy control irrigation method for rice seedling raising on hard ground. Background technique [0002] The traditional irrigation method for rice seedling raising on hard ground consumes a lot of water. Water saving and energy saving are two important ideas of intelligent irrigation. Water saving is particularly important when the frequency of irrigation operations is low. According to seedling production practices, improper irrigation will result in a 10%-30% reduction in seedling production. With the development of information technology, sensor networks and automation have been widely used in modern agriculture, and modern intelligent irrigation has gradually replaced traditional irrigation methods. The basis of intelligent irrigation is usually the determination of planting soil moisture and the calculation of crop water demand. The measurement of soil mo...
