Abstract:In order to improve the performance of stabilized platform, research and develop a data acquisition and processing system for various gyros in stabilized platform to achieve high speed, high accuracy and wide dynamic range. The system design requirements are proposed based on detail analysis of several typical gyros, such as dynamically tuned gyro (DTG), fiber optical gyro (FOG) and MEMS gyro. In the meanwhile, 8 channels and 24 bitsΣ-Δ analog-digital converter ADS1278 and 32bits digital signal processor TMS320F2812 are chosen to design and realization the hardware circuits, and also the software program is compiled. The experiment result shows that the errors of data acquisition and processing system are less than 1%, which can meet the requirements of stabilized platform gyros.
