Background
When a carrier rocket and a missile carry out the mode flight of a technical place and a launch place or the model development of a laboratory, a lot of tests are needed from a preparation stage before takeoff to the end of flight in an active section, millions of parameters of various types of signals are generated in each test, whether the parameters are normal or not needs to be carefully distinguished, the method is a complicated work and is very easy to make mistakes. The interpretation of these test data is also subject to different interpretation requirements in different processing cycles. The time left for interpretation within the transmission preparation procedure is very short, and manual means are simply not possible to accomplish a detailed interpretation of the test parameters.
In the prior art, interpretation of test parameters generally involves more manual intervention. And (3) if the analog signal is out of tolerance: firstly, an operator needs to print a time curve graph of test data and a data comparison parameter table; then comparing the normal parameter variation ranges one by one according to the criterion list documents, and marking the over-tolerance data in the graph; finally, forming an interpretation conclusion and manually recording. The working efficiency is low, the test and test requirements of a plurality of acquisition channels and huge data volume cannot be met, and the credibility of the interpretation result is difficult to ensure. In addition, there are some automatic interpretation systems that can implement upper and lower limit interpretation of analog signals. The interpretation function only aims at analog signals, the criterion mode is fixed and is not easy to expand, the method cannot be used for interpretation of parameters such as time sequence time series and pulse counting, cannot adapt to interpretation of various information of different test items, and is lack of expandability.
At present, for the interpretation of data, the criterion in the real-time interpretation processing stage and the criterion in the post-interpretation processing stage are the same, and the different requirements of the test on the real-time interpretation and the post-interpretation are not considered. In the real-time interpretation stage, in order to ensure the real-time performance of data interpretation, the interpretation requirement is relatively simple, generally, the upper and lower limits of data at the current moment are interpreted, and the sub-health state of some equipment cannot be judged; in the case of after-the-fact interpretation, in order to better mine the rules in the test data, the hidden sub-health state in the real-time interpretation stage needs to be more comprehensively interpreted, and the overall interpretation of the data is carried out, so that the test task is comprehensively and deeply analyzed.
