Design Of The Space Seat’s Acquisition And Control System

In recent years, with the continuous expansion of cultural and creative, virtual space travel has been widely welcomed. The space seat as a carrier has the value of research and development. Based on this, the space seat’s acquisition and control system is designed.The system is divided into three parts:seat control system, joystick design and display terminal design. The seat can move up and down or swing around. The joystick achieves the basic functions, including the direction keys, numeric keypad and its throttle. And you can customize the device functions. Character is displayed on the LCD monitor through the display terminal.It’s simple and smooth.Control system is designed with microcontroller as the core, peripheral with serial communication circuit, relay driver circuit and the A/D sampling circuit. Control program is developed based on the hardware platform. Based on AT90USB162microprocessor,the joystick system is designed. USB communication circuit and USB interface program are designed based on the USB enumeration process and data transmission process. Display terminal system is developed on FPGA platform,combined with video D/A converter chip to control the VGA display. In the design process, the design of hardware circuit,the working principle and development process of FPGA and the VGA timing are introduced in detail in this paper.After debugging and testing, the data acquisition and control system has high stability, and can realize the extended function according to changes in demand. So the system has high research and application value.
