[Abstract]:With the development of inertial technology, the precision of strapdown inertial navigation products has been improved, and the performance index of test equipment has been improved. In the process of research and development of strapdown inertial navigation products and production and testing, testing equipment is needed to calibrate and calibrate strapdown inertial navigation products, and the error models for compensation in navigation are obtained. In order to improve navigation accuracy and reduce navigation error of strapdown inertial navigation products, the test technology and test method of special test equipment for strapdown inertial navigation products are studied and implemented. The output signal acquisition and processing of strapdown inertial navigation products are studied and realized. This paper first introduces the research background and research status of inertial navigation technology and test equipment. Secondly, the design scheme of data acquisition and processing in Strapdown Integrated Inertial Navigation Test system is described in detail, and the multi-type analog signal conditioning and processing is realized by using the self-developed universal transmission module. Based on PCI bus 16-channel optocoupler isolation pulse data acquisition card is developed to realize multi-pulse synchronous counting of gyroscope and accelerometer. The principle and design scheme of data acquisition unit are described in detail. Finally, the test data and error are analyzed. The part of data acquisition and processing in this paper solves the requirement of verification and calibration of strapdown integrated inertial navigation system compatible with many types of inertial navigation products.
