Abstract

The invention discloses a lifting stage control device and a control method. The lifting stage control device comprises a main controller, a PLC (programmable logic controller), a plurality of alternating current servo motors, lifting tables, current sensors, at least one position sensor and rotating speed sensors, wherein the number of the lifting table is the same as that of the alternating current servo motors, the current sensors are respectively arranged on each alternating current servo motor, the at least one position sensor is arranged on each lifting table, the rotating speed sensors are respectively arranged on each alternating current servo motor, the PLC is electrically connected with each alternating current servo motor, each alternating current servo motor is electrically connected with the corresponding lifting table, the rotating speed sensors, the current sensors and the position sensor are respectively and electrically connected with the main controller, and a display screen is arranged on the main controller. The lifting stage control device and the control method have the characteristics that the stage lifting conversion efficiency is ensured, the safety requirement of actors in the performance process is also ensured, the modification cost is low, and the multi-operational modes of stages in the unloaded and loaded states can be realized.

Description

Technical field [0001] The invention relates to the technical field of stage control, in particular to a lifting stage control device and a control method with good safety and high lifting efficiency. Background technique [0002] The existing lifting stage usually adopts PLC+servo control motor to realize the stage operation. In terms of artistic expression, it adopts the setting PC program or manual control by the workers after the performance. The realization method is operated based on experience, which is relatively primitive. The labor intensity of the workers at the back of the performance is high, the control accuracy is poor, and some difficult stage actions cannot be achieved; in terms of performance safety, the traditional elevator control device only takes personal safety as the first consideration, and sacrifices some of the elevator Action requirements, such as whether the actor is on the stage or not, can only achieve the slow rise or fall of the lifting platform, ...
