The Design And Research On Stage Trolley Based On Servo-driven Technology

This topic deeply analyzes the real-time requirements of the real-time interactive function of the stage,and develops a three-degree-of-freedom configurable programming stage mobile trolley and control system based on servo drive technology.The system adopts the two-level networked cooperative servo drive technology to solve the problem of synchronous operation of multiple servo motors or cars.The configurable programming technology realizes off-line programming,real-time control and form reconfigurability of the trolley system,group programming and other functions,the car can not only be in a set time to ensure that the car presents a specific shape or display effect,but also can achieve on-site recovery in case of sudden power failure at the preset time,position and input conditions.The function can also carry or actively cooperate with the actor to complete the pre-set moving track on the stage.The stage uses mobile manned vehicles to integrate mechanical,control,communication,computer,artificial intelligence and other technologies.It has good robustness,high real-time performance and easy programming.First of all,this paper deeply analyzes the design of the overall system architecture of the mobile drive car for the servo drive stage to meet the manned,omnidirectional movement,multi-point servo cooperative control,information fusion positioning,and can form a motion shape library based on database programming.Information interaction and monitoring alarms,configurable programming and other functional requirements.Secondly,the in-depth theoretical analysis of the dynamic system of the mobile trolley for the stage is carried out,and the design of the reliable mechanical mechanism is designed.The omnidirectional movement control technology is adopted to realize the function of free rotation without turning radius,and the monitoring and dispatching PC is constructed.A two-level distributed network control system is formed between the network controller and the network controller and the independent servo drive.Thirdly,a configurable programming monitoring and scheduling platform is designed.Based on the periodic time-driven technology,the platform completes the functions of configurable programming and real-time monitoring and scheduling.Finally,the core problems of the car network and monitoring and dispatching system are debugged and analyzed in depth,and the important methods that can be optimized are prospected.
