and step S8, if △ G2 is not less than △ GH and P2 is not less than P0, delaying △ t to judge P1 again, if P1 is not less than P0, reducing P1, measuring the roller deviation away from the driving side to be △ G22 until △ G L < △ G22< △ GH, stopping driving the propulsion oil cylinder, and if P1< P0, not driving the propulsion oil cylinder.
6. The control method of claim 5, wherein the oil pressure analog signals of different propulsion cylinders are collected by an oil pressure sensor to a P L C control module, and the analog signals are converted into digital signals by the P L C control module.
7. The control method according to claim 5, wherein the P L C control module generates a determination signal to the adaptive control module, and the adaptive control module generates a driving electric signal to the execution module to drive the propulsion cylinder.
8. The control method according to any one of claims 5 to 7, further comprising a step S9, wherein the step S9 is to collect the driving motor current signal, convert the driving motor current signal into a digital signal D1 in the P L C control module, compare the digital signal with the current set value D0 and the duration set value T0, and if D1 is greater than or equal to D0 and the duration △ T1 is greater than or equal to T0, generate an electric signal to the adaptive control module, and generate a driving electric signal by the adaptive control module until the execution module drives each propulsion cylinder.
9. The control method of claim 8, wherein the adaptive control module generates a driving electrical signal to the actuator module to drive the retraction cylinder.
10. A storage medium, comprising a stored program, wherein the program, when executed, controls an apparatus in which the storage medium is located to perform the method of any of claims 5-9.
