Underground coal mine intelligent frequency conversion integrated fracturing pump control system and control method

The invention discloses a coal mine underground intelligent frequency conversion integrated fracturing pump control system and method, and the system comprises a pump module, a permanent magnet motor module, an integrated frequency converter module, a pump station special control room module, a pump station special mobile transformer, a pump station water tank and a water supply system. Fracturing equipment modules are freely expanded according to requirements, and a plurality of fracturing pump sets are connected in parallel, so that accurate control over fracturing duration, fracturing flow and fracturing pressure is achieved, the application range of fracturing and the working condition matching degree of fracturing are improved, the pressure and flow adjusting ranges of different geological conditions are met, and the fracturing efficiency is improved. The coal mine underground kilometer directional hydraulic fracturing control system realizes accurate control of the fracturing effect of a coal mine under
