The invention discloses an automatic blasting high-pressure gas generation system which comprises a high-pressure gas generation bottle, a protective box, an MCU controller, and an external device. The high-pressure gas generation bottle is fixedly installed in the cavity of the protective box through a base. The right side of the high-pressure gas generation bottle is connected with multiple high-pressure pipelines. A high-pressure gas flow sensor is arranged on the inner wall of each high-pressure pipeline. The left side of the high-pressure gas generation bottle is connected with an L-shaped blasting pipeline. A communication device, a power supply and a mainframe box are installed on the left side of the inner wall of the protective box in sequence from top to bottom. The input end of the MCU controller is electrically connected with the output ends of a high-pressure gas pressure sensor, a temperature sensor, the high-pressure gas flow sensors and the power supply. The MCU controller is electrically connected with the communication device. The automatic blasting high-pressure gas generation system has high degree of automation, high safety performance and high practicality. High-pressure gas flow output can be monitored in real time.
