分布式高炮复合数据同步采集系统

摘要

为满足分布式高炮测评系统对复合数据采集的实时性和同步性需求，解决异步数据影响测评系统准确性的问题，提出分布式高炮复合数据同步采集系统。该系统由多个复合数据采集终端组成，复合数据采集终端基于I.MX515 ARM处理器和Linux实时操作系统并具有复合数据实时采集功能和GPS接口，多个复合数据采集终端之间通过GPS授时同步和时间戳同步技术确保数据的时间相关性。结果表明：该系统设计合理，能保证分布式高炮测评系统原始数据同步，提高武器射击评价系统的准确性和鲁棒性，已成功应用于某高炮射击成绩测评系统中。%For the purpose of real-time and synchronization acquisition of compound data in distributed anti-aircraft gun system, to solve the problem of asynchronous data affect the accuracy of the measurement system, a synchronous acquisition system of distributed anti-aircraft compound data is put forward. The system is composed of multiple composite data acquisition terminals. The compound data acquisition terminal based on I.MX515 ARM processor and Linux real-time operating system has the function of complex data real-time acquisition and GPS interface. Use GPS timing synchronization between multiple composite data acquisition terminals and timestamp synchronization technology to ensure that the data of time correlation. Results show that the system design is reasonable, and can keep the original data synchronization to improve the accuracy of the evaluation system of weapon shooting and robustness. It has been used in certain type artillery firing evaluation system.
