Research And Development Of4D Motion Seat Control System Based On PC And PLC

At present, the4D dynamic movie as a type of new developed film, it contains film art, computer technology, automatic control technology and other high and new technology, and it has better effect expression of movie arts. Relative to the comon3D movie, more attractive4D dynamic movie has very unique advantages. It adds the realistic seat action effects imitating action in the movie scene, and surrounding transformation between the wind, storm, thunder and various kinds of smell changes. These two effects are implemented by dynamic seat and special equipment. According to the content of the movie, dynamic seat makes the corresponding imitate action, let the audience feel very strong feeling of Sporty experience. Coupled with the visual impact brought by the film, it can produce a kind of live fast and prosper, immersive, fantasy film experience.For all sections of4D dynamic cinema’s whole complex work system, among of them, the control system of seat’s movement plays a significant character. It is controlling of its dynamic seat make imitation actions and the special effects similar to movies. The study of4D dynamic seat in China started late, in comparison to other developed countries, the development of4D dynamic seat control technology is comparatively backward. Depending on the project in an enterprise, in consideration of4D dynamic seat control system requires higher stability and security, and it requires easy operation, low price and high accuracy action etc. Based on consulting many relevant aspects of the resources and making the on-the-spot investigation of many domestic existing4D dynamic seat, aiming at a certain type of three degrees of freedom’s dynamic seat with hydraulic control, this topic has made the detailed analysis and design, then developed a servo control system based on PC and PLC control. Combining with dynamic seat and hydraulic transmission mechanism, this topic produced a prototype of4D dynamic seat system. And this topic make comprehensive functionalsy stemic experiment of the prototype, the test consequences reveal that the control system achieved design control requirements and capabilities, and the feasibility of4D dynamic seat control system based on PC and PLC proposed by this topic is verified.This topic use CP1E type PLC of omron company as the core components of the control system In the design process of4D motion seat based on PC and PLC control system,and join analog input/output unit,digital proportional amplifier,linear displacement sensors and other components in the system,complet the hardware circuit design for a certain type of4D motion seat control system.On the basis of the working principle and functional characteristics of the all parts in control system,and manufacture PLC control cabinet meeting the requirements of control,then write corresponding control program of PLC with the help of CX-Programmer tool software.Then in the exploitation circumstance of Windows application platform, employing Microsoft Visual Studio2010programming tool software,and applying object-oriented C++programming language compile control software on PC. Finally according to the overall design scheme of this topic, make integration of the hardware and software of the control system and, basic machine and hydraulic transmission mechanism of seat, produce the prototype and test.
