摘要
运载火箭每一次模拟飞行试验会产生大量的飞行时序,为了验证飞行过程的正确性,系统人员要花费大量的时间和精力进行判读,且由于受主观影响,判读的可靠性较低。本文以应用在某新型运载火箭控制系统中的飞行时序自动判读技术为背景,介绍了一种新颖的时序自动判读技术,该技术利用数据库和三维哈希表实现了时序的实时定位和全自动判读,不仅满足了时序在飞行过程中的实时自动判读需要,也为飞行结束后的分析提供了可靠的判读结论,减轻了时序判读人员的工作量,提高了箭上软件的可靠性。
A lot of flight time-sequences appear during launch vehicles flight.The verification is the time-consuming,sensitive and exhausting work for the system staff because of the subjective reason.In this paper,a new time-sequences auto-verifying method based on the database and three-dimensional Hash tables is presented by means of application on control systems of some new type launch vehicles.By this new method,the real-time location of bus time-sequences and whole auto verification are realized.
