冲击波超压时基同步存储测试技术
Time-based synchronous storage testing technology for shock wave overpressure
摘要
Abstract
Shock wave overpressure testing is an important means of evaluating weapon performance,and its testing process requires the testing equipment to have multi-channel,high-capacity data storage and accurate recording functions of shock wave signal triggering time.On this basis,a time-based synchronous storage testing technology for shock wave overpressure is proposed.In this technology,based on GPS satellite timing technology,the device system clock is calibrated by means of serial data and PPS signals output by the GPS module.The multi-channel data storage technology is used to realize the management of data storage space and the retrieval of storage data file.The experimental results prove that the time-based synchronization error between the acquisition devices is 256 ns,and the proposed data storage technology can achieve a writing speed of 18.45 MB/s,which can ensure the storage of data integrity and the stable storage of the acquisition device data.关键词
