Automatic adjusting system for underground flow regulator and operation method of automatic adjusting system

The invention discloses an automatic adjusting system for an underground flow regulator and an operation method of the automatic adjusting system. A measuring short joint framework arranged at the upper end of a flow regulator anchoring mechanism is included and provided with a DSP, the DSP is connected with a sensor set and a motor assembly, and a signal conditioning and data collecting unit is arranged between the DSP and the sensor set. The sensor set is used for collecting air nozzle front-back pressure, temperature and air nozzle aperture parameters, the air nozzle front-back pressure, temperature and the air nozzle aperture parameters are sent to the DSP through the signal conditioning and data collecting unit, the DSP controls the motor assembly to adjust the aperture of an air nozzle through changing of the circulation area between a valve element and a valve base according to the received information, and automatic adjustment is achieved. The automatic adjusting system for theunderground flow regulat
