Abstract

The invention discloses a lifting stage control device and a control method thereof. The lifting stage control device comprises a master controller, a PLC (programmable logic controller), a plurality of servo motors, lifting platforms, pressure sensors, position sensors and rotating-speed sensors. The number of the lifting platforms is as same as that of the servo motors. The pressure sensors are arranged on the lifting platforms. At least one position sensor is arranged on each lifting platform. The rotating-speed sensors are arranged on the servo motors. The PLC is electrically connected with the servo motors. The servo motors are electrically connected with corresponding lifting platforms. The rotating-speed sensors, the pressure sensors and the position sensors are electrically connected with the master controller respectively. A display screen is arranged on the master controller. The lifting stage control device and the control method thereof have the advantages that lifting conversion efficiency of a stage and safety needs of performers during performance can be guaranteed, modification cost is low, and multiple operating modes of the stage in an unloaded or loaded state can be realized.

Description

technical field [0001] The invention relates to the technical field of stage control, in particular to a control device and control method for a lifting stage with good safety and high lifting efficiency. Background technique [0002] The existing lifting stage usually uses PLC+servo control motor to realize the stage operation. In terms of artistic expression, it is realized by setting PC program or manual control by the workers after the performance. In terms of implementation method, it is relatively primitive to operate by experience, resulting The labor intensity of the workers in the backstage of the performance is high, the control accuracy is poor, and some difficult stage actions cannot be realized; in terms of performance safety, the traditional lifting platform control device only takes personal safety as the first consideration, sacrificing some of the lifting platform. Action requirements, such as whether the actor is on the stage or not, can only realize the sl...
