The invention provides an intelligent liquid supply method for a fully mechanized coal mining face, a storage medium, electronic equipment and a system. According to the method, coal mining equipmentaction data and a pump station outlet pressure value in a historical time period are iteratively trained through a preset machine learning model, so that the relation between the pump station outlet pressure value and the coal mining equipment action data at the same moment is determined, and an outlet pressure value pre-estimation model is obtained through iterative training. After the action data of coal mining equipment are input into the outlet pressure value pre-estimation model, the target pressure value of the outlet of a pump station can be estimated in advance, and the opening, closing or working frequency of each pump body in the pump station is controlled according to the pre-estimated target pressure value of the outlet of the pump station, so that the liquid supply pressure and the liquid supply quantity can be immediately regulated and controlled, the lagging defect does not exist, and the production efficiency of a working surface is greatly improved.
