The Data Acquisition System Of The Rigid Body Measuring And Data Processing Technique

The technique of measurement position and attitude of the dynamic target is InertialTechnology. It involves many areas and includes military, aerospace, maritime transport, landtransport, etc. It is quite a wide range of applications, especially in the military field, andachieved substantial results. Many of the practical application of technology is very mature.With the continuous development of inertial technology needs in the area and control ofnavigation, strapdown navigation system has been very good development. With thetraditional platform inertial systems, strapdown system with high reliability, small size, lightweight, relatively low cost, however, low accuracy. So strapdown navigation system suitablefor use in medium-accuracy and low cost requirements of the occasion.This paper introduces the basic principle of MEMS sensors and structuralcharacteristics, and briefly describes the system used in the STM32microcontroller, wirelesscommunication modules and systems for data processing of the basic process, explain thebasic working principle of this system and the theoretical support, the system introduces thebasic theory of strapdown navigation algorithm. The main work is as follows:1. Constitute the moving object detection device of the attitude information to themicroprocessor core. The use of wireless transmission of data into the computer.2. Attitude information of the detected conversion called the object motion informationby Strapdown navigation algorithm.3. Algorithm is written to the host computer software with VC. Calculation data areplotted to the screen.4. To test the object of some special state of motion, and according to thedata on the analysis of algorithms and sensors.This paper describes the system hardware and PC software constitutes a principle ofdesign ideas, and finally the system of sensors and algorithms of the test, and the analyzed theresult.
