Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] Such as figure 1 , the dynamic seat control system includes 1 PC (host computer), 1 main controller PLC (Omron), 1 A / D module, 1 D / A module, 1 switching power supply, 3 proportional amplifiers, 3 linear displacement sensors, 3 hydraulic cylinders, 3 electromagnetic proportional directional valves, 1 electric motor, 1 hydraulic pump, and 1 electromagnetic overflow valve.

[0017] After the host computer (PC) control program reads the pre-programmed action file, it sends the position control command of the 4D dynamic seat to the PLC through the serial port communication, and the PLC outputs the analog quantity after being converted by the D / A module according to the command of the host computer. The signal is sent to the proportional amplifier, and then the amplified analog signal is output to the electromagnetic proportional directional valve to control the openi...

Abstract

A new 4D cinema dynamic seat control system adopts a closed-loop control method with position feedback, which ensures the accuracy of position control and improves the reliability and stability of system motion control. It can realize the three freedoms of lifting, pitching and rolling High-speed motion, which can simulate various motion scenes in movies. The system works stably, the action simulation is more realistic, and can give the audience a more realistic sense of presence, and the performance is stable and the cost is low, so it has a good prospect for promotion and application.

Description

Technical field [0001] The invention relates to a novel 4D cinema dynamic seat control system, which is suitable for the mechanical field. Background technique [0002] With the development of film technology, there has been a wave of 4D motion film fever in recent years. This special film is a high-tech system engineering that combines virtual reality technology, computer network intelligent control technology, automatic control technology and film art. The core component of 4D dynamic movie is the dynamic seat. Its main feature is that when the audience enjoys the movie, the dynamic seat also makes corresponding imitation actions with the evolution of the plot on the screen, giving the audience a strong immersive experience. and a sense of thrill. It can generally do movements in three directions, namely lifting movements, left and right tilting movements and forward and backward pitching movements. Most of the dynamic seats need to be imported and are very expensive. A ...
