Embodiment 1

[0039] see figure 2 As shown, the sprinkler execution module includes an annular track water tank 1, which is installed on the outside of the farmland, the outer wall of the annular track water tank 1 is equipped with a water inlet pipe 2, and the inner wall of the annular track water tank 1 is provided with several mobile water pumps 3 , the output end of the mobile water pump 3 is provided with a nozzle 4, the number of the nozzle 4 and the mobile water pump 3 can be set according to the size of the farmland, in the actual implementation process, the number of the nozzle 4 and the mobile water pump 3 is usually selected as three to five. The shape of the farmland is circular, and the center of the farmland coincides with the center of the circular track water tank 1. The spraying distances of several nozzles 4 are different, and the sum of the spraying ranges of all the nozzles 4 completely covers the farmland, that is, with the mobile water pump 3 Continuously moving on t...

Embodiment 2

[0041] see image 3 As shown, the growth monitoring module is used to analyze the growth state of the crops in the farmland: divide the farmland into growth areas i, i=1, 2, ..., n, n is a positive integer, take color images of the growth area i and The captured color image is enlarged into a pixel grid image i, and the color feature extraction is performed on the obtained pixel grid image i through the feature extraction technology to obtain the green feature component of the pixel grid. In machine learning, pattern recognition and image processing, the feature extraction starts from the initial We start with a set of measurement data for , and build derived values ​​(features) that are intended to be informative and non-redundant, thereby facilitating subsequent learning and generalization steps. Sum the green feature components of all the pixel grids of the pixel grid image i and take the average to obtain the green performance value LBi of the pixel grid image i; obtain th...

Embodiment 3

[0046] see Figure 4 As shown, the specific process of the difference analysis model to analyze the growth difference of growth area i includes: establishing force growth set {SZ1, SZ2, ..., SZi}, calculating the variance of the growth set and marking the obtained value as the difference coefficient CY, the difference coefficient is a reflection of the degree of deviation between the growth state of crops in a single growth area and the standard state. The larger the value of the difference coefficient, the more the number of unqualified growth areas in the overall qualified farmland, and the unqualified The worse the growth state of the crops in the growing area, the worse the growth balance of the crops in the farmland. The difference threshold CYmax is obtained through the storage module, and the difference coefficient CY of the growth set is compared with the difference threshold CYmax: If the difference coefficient CY <difference threshold CYmax, it is determined that the...

Abstract

The invention relates to the technical field of farm irrigation, is used for solving the problem that an existing farm irrigation system cannot check abnormal reasons when crops grow abnormally, and particularly relates to an internet-based farm irrigation analysis control system, which comprises a control platform, the control platform is in communication connection with a spraying execution module, a growth monitoring module, an anomaly analysis module, a spraying analysis module and a storage module, the spraying execution module comprises an annular track water tank, a water inlet pipe is installed on the outer side wall of the annular track water tank, and a plurality of movable water pumps are arranged on the inner side wall of the annular track water tank; sprayers are arranged at the output end of the movable water pump, and the spraying distances of the multiple sprayers are different. According to the invention, through the growth monitoring module, the growth state of the crops can be detected and analyzed according to the growth characteristics of the crops, and the phenomenon that abnormal growth of the crops in individual growth areas is ignored due to the fact that overall growth is qualified is prevented.

Description

technical field [0001] The invention relates to the technical field of farmland irrigation, in particular to an internet-based farmland irrigation analysis and control system. Background technique [0002] Soil water potential is the intensity index of soil moisture and the determination of the direction of soil water movement. It is closely related to the effectiveness of water absorption by plants. It is an important irrigation control index for crop water supply in farmland. Nutrient organs have an important impact on crop growth and yield formation; [0003] However, the existing farmland irrigation control system can only spray the crops regularly and quantitatively, but cannot detect the overall growth status and growth differences through the characteristics of the crops, and also check the abnormal causes when the crops grow abnormally. There are many factors that affect the growth status of crops, and it takes a lot of manpower and time to manually check one by one...
