Fiber Optic Gyro Automatic Test System

The performance evaluation of fiber-optic gyro is a very important aspect of fiber-optic gyro design. A comprehensive, rapid and standard automatic test system is necessary to detect parameters of fiber-optic gyro to meet the actual test requirements. The paper focuses on the software design of fiber-optic gyro automatic test system.In the performance evaluation of fiber-optic gyro, many projects are very similar. In order to improve the reliability and scalability of test system, the software design of fiber-optic gyro automatic test system uses a separation model with testing platform and specific test projects. Testing platform is responsible for collecting and displaying data, test projects are responsible for controlling the assisted test equipment and make some simple calculations. Specific test projects connect with testing platform through the dynamic link library.In data collection module of testing platform, multi-thread technology is used to collect multi communication ports, it can reduce system resource occupancy and speed up data collection. General data frame format method is used to receive the data flow in the different format. By this method, the problem of communication format adaptation can be solved and the application range can be expanded. In data display module of testing platform, floating window is used to display real-time collection data and statistics of real-time collection data. In data plotting module of testing platform, the attribute page is used to switch single channel data plotting or multi-channel data plotting to show. In data storage module of testing platform, with the design idea of dual-buffer exchange for storage, fiber-optic gyro automatic test system can realize the massive data collection and storage.In actual applications, fiber-optic gyro automatic test system is stable and accurate. It achieves to the design requirements and meets the requirements of performance evaluation.
