摘　　要：针对武器装备在总装测试中出现的接口时序不匹配,现有测试方法不能实现长期连续自动测试的问题,提出基于层次有向图的时序一致性测试方法。该方法首先通过建立接口时序的层次有向图模型实现标准时序描述,然后利用错误检测算法实现异常时序的检测和定位。实验结果表明,该方法能够对通信周期内单个逻辑性错误的异常时序实现准确检测,对不收敛的异常时序能实现完全检测,适用于单个错误的异常时序检测。Aiming at the problem that the timing of the interface of the weapon equipment in the final assembly test did not match well,the existing test method cannot achieve long-term continuous automatic testing,a timing consistency test method based on directed graph was proposed.This method firstly implemented the standard timing description by establishing a hierarchical directed graph model of interface timing,and then used the error detection algorithm to realize the detection and location of abnormal timing.The experimental results showed that this method could accurately detect the abnormal timing of single logical errors in the communication cycle,and could completely detect the abnormal timing of non-convergence,which was suitable for the detection of abnormal timing of single errors.
