Intelligent injection system

The invention discloses an intelligent ejection system which comprises an ejector, a monitoring module, a gas concentration prediction module, an ejection flow adjusting module and a spray cavity containing box. The ejector is provided with a plurality of spraying cavities with different calibers, and the spraying cavities are horizontally embedded in the spraying cavity containing box. The monitoring module is used for monitoring basic data of a working area and transmitting the basic data to the gas concentration prediction module; a gas concentration prediction model based on TSO-XGBoost is stored in the gas concentration prediction module; the gas concentration prediction model takes basic data of a working area as input, predicts gas concentration in a future time period and transmits the gas concentration to the injection flow adjusting module; the injection flow adjusting module selects a to-be-used spraying cavity according to the gas concentration and drives the spraying cavity containing box to move
