Embodiment 1
[0088] An irrigation method based on dynamic double-layer extreme learning machine such as figure 1 As shown, the data related to the known irrigation water demand is collected and normalized, and then the double-layer extreme learning machine is trained to obtain the final prediction model, and the data related to the expected irrigation water demand is normalized and input to the final Irrigate after the prediction model obtains the predicted irrigation water demand, and the specific steps are as follows:
[0089] (1) Collect the soil environment data and meteorological data of the farmland. The collected soil environment data and meteorological data come from the agricultural Internet of Things equipment developed by the Information Center of the Shanghai Municipal Agriculture Commission, including the daily average temperature and humidity of the soil, the average daily temperature and humidity of the air, The daily average total solar radiation, the wind speed at a height...
Embodiment 2
[0140] An irrigation method based on a dynamic multi-layer extreme learning machine, the method is basically the same as that of Embodiment 1, the difference is that the multi-layer extreme learning machine is a three-layer extreme learning machine, and the selected data is a total of 5000 groups, divided into 10 Data block, the coefficient of determination R of the prediction index between the predicted irrigation water demand and the actual demand value obtained from the final calculation 2 =0.97405, the predicted results are the average values obtained by running the program 20 times.
