CONTROL METHOD AND CONTROL SYSTEM FOR ROTATION MECHANISM OF ENGINEERING MACHINERY AND ENGINEERING MACHINERY

摘要

Provided in the present invention are a control method and control system for a rotation mechanism of an engineering machinery and the engineering machinery, for use in solving the problem of poor reliability in the prior art of using an RCV controller to control the rotation mechanism of a tower crane. The method comprises: a controller of the engineering machinery receiving a speed command signal, converting the speed command signal into a power control signal required by a power controller then transmitting to the power controller; the power controller converting the power control signal into a control signal of a power module then transmitting to the power module; and the power module controlling a torque motor of the rotation mechanism on the basis of the control signal transmitted by the power controller. Employment of the technical solution of the present invention allows for improved reliability in controlling the rotation mechanism of the tower crane.
