Reliability test device for wind turbine generator overhaul elevator and control method

The invention discloses a reliability test device for a wind turbine generator overhaul elevator and a control method, and belongs to the technical field of reliability test devices for elevators. A driving motor rotates forwards to take up a traction rope to drive a lifting bin to lift, a stop signal for controlling the driving motor to stop running is obtained, and the lifting bin is stopped when the driving motor stops running; a signal for driving the lifting bin to descend is obtained, an operation signal for driving the driving motor to operate is sent out to drive the driving motor, the driving motor rotates reversely to release the traction rope, the lifting bin descends under gravity, a stop signal for controlling the driving motor to stop operating is obtained, and then the lifting bin is stopped. Wherein the operation of the driving motor is controlled by remote control triggering, the operation of the driving motor is controlled by a stroke counter, the operation of the driving motor is controlled
