Parameter calibration control method suitable for excavator

The invention belongs to the technical field of excavators, and particularly relates to a parameter calibration control method suitable for an excavator. The parameter calibration control method comprises the specific work flows that a terminal P1 retrieves positions of an index number and a sub-index number of a parameter A; an a2 value is sent to a controller P2 in an index channel through a CANbus; the controller P2 receives a change value a2 of the parameter A through the CAN bus and judges whether a2 is consistent with a current value a1 of the parameter A of a storage area or not, if yes, the a1 of the storage area is changed into a2, a calibration success result is fed back to the terminal P1, and if not, the step 4 is executed; and the controller P2 judges whether the received a2value conforms to the precision, range and access type of the parameter or not, if not, the a1 of the storage area is kept unchanged, and a calibration failure result is fed back to the terminal P1, otherwise, the a1 of the st
