Based On The Design Of Special Vehicles Gyroscope Attitude Solver

With the economic development in today's society, people's material cultural level is getting higher and higher, the automobile is becoming increasingly popular, it's necessary to master the automobile driving skills, the most important issue in automobile driving is security. With the development and application of gyroscope sensor technology, measurement technology and DSP technology, the automobile intellectualization level is increasingly high, the automobile emulated driving system develops rapidly, and the range of application is very wide. This paper presents an attitude algorithm device based on the combination of gyroscope and DSP technology, it is used in the special automobile emulated driving system, the main function is to process the attitude data of model automobile sampled by the gyroscope and simulate the model automobile attitude.This passage firstly introduces the principle of MEMS Gyroscope sensor, in this project, we select ADIS16355 MEMS gyroscope sensor produced by ADI company to sample the data of model automobile, on the base of reading mass correlative references, the DSP TMS320F2812 of TI is used as the control core, choose attitude algorithm device as the study object, analyze the data sampled by gyroscope on the model automobile, design the automobile attitude algorithm device based on gyroscope.After analyzing the data sampled by ADIS16355 gyroscope on the model automobile, according to demand of the system we work out the whole design of the attitude algorithm system, and present the scheme of hardware design and the software design. The hardware designs mainly include MCU, power supply, clock, reset, Jtag, UART, TOP board and so on, to meet the accuracy requirement of the attitude algorithm system in software, the main system program, the initialization program, the interrupt program, data processing program and so on are compiled with C language in the environment of CCS.Finaly, I do the test through experiment based on the hardware design platform, and provide the output wave of the attitude algorithm device. The result of experiment is satisfactory, it means the design of experimental platform is rational, and also reaches the accuracy requirement, at last we give the summarization of the thesis.
