针对冲击波超压测试中存在时基统一性差、存储数据难以及时获取等问题,设计了一种具有时基统一和关键数据快速获取功能的冲击波超压测试系统。系统通过北斗授时模块对测试节点精确授时,并利用外置触发导线断线瞬间产生脉冲使多个测试节点同时启动,实现时基统一;运用内触发地址回溯检索,精确定位关键数据存储位置,使用无线终端完成关键数据的获取。实验表明该系统能够确保多个测试节点时基统一以及关键数据的快速准确获取。

Aiming at the problems such as the poor time base unity and the difficulty in obtaining the saving data in the shock wave over-pressure test, a shock wave overpressure test system with timebase unification and rapid acquisition of key data was designed. The system uses the Beidou timing module to precisely test the test node and an external trigger wire was used to instantly generate a pulse so that multiple test nodes can be started at the same time to achieve timebase unification. By using the internal trigger address backtracking, the key data storage location can be accurately located and the radio is used to complete the acquisition of key data. Experiments show that the system can ensure the timebase unity of multiple test nodes and the fast and accurate acquisition of the key data.
