Embodiment Construction

[0017] It can be known from the background technology that if a certain indicator is out of tolerance during missile testing, it will immediately go to the missile fault diagnosis process. However, when conducting missile fault diagnosis, the current missile fault diagnosis is to test all the test items of the entire missile one by one; the current missile fault diagnosis method is inefficient. The inventor's research found that the production conditions are the same or close, and the faulty parts of the missiles in the same batch or several adjacent batches have a certain correlation. Therefore, by writing a missile fault prediction software, the most likely fault location is analyzed from the historical diagnosis records, so that the fault diagnosis software can diagnose and analyze more specifically, which can improve work efficiency and greatly shorten the test time.

[0018] The present invention will be further described below in conjunction with the drawings and embodiment...

Abstract

The invention provides a novel missile fault prediction device which is widely used in the aerospace automation measurement and control technical field. The device is mainly composed of a PXI measurement and control system, a KVM integral machine, a printer, a test cable, a historic fault database, and missile fault prediction software. By combining virtual apparatus technologies and automatic measurement and control technologies, the device is in direct butt joint with the missile fault prediction software. All previous missile fault diagnosis results are automatically stored in the historic database, and by employing a prediction algorithm, a next possible fault position is predicted, and a part most likely to break down is found, thereby helping the missile fault prediction software to rapidly determine a fault scope, and avoiding a diagnosis mode starting diagnosis from a fixed source. The device can effectively reduce diagnosis time and improve test efficiency, possesses higher use values, and is already applied to the test and fault diagnosis filed of missiles in various tactical models.

Description

Technical field [0001] The invention relates to the field of aerospace automatic measurement and control technology, in particular to a device and method for storing missile fault data, automatically performing algorithmic analysis on historical fault data, and giving conclusions, and finally helping testers to quickly complete missile fault diagnosis. Background technique [0002] Missile fault prediction software is mainly used in the fault diagnosis of missiles. Each missile must undergo a rigorous final assembly test before it leaves the factory. If an indicator is abnormal during the test, it is necessary to diagnose the missile immediately. The fault diagnosis of missiles currently has a dedicated equipment platform, and there is a dedicated fault diagnosis software to realize diagnosis automation. [0003] However, because the problem of an indicator often corresponds to multiple components on the missile, and there are often several correspondences between the various com...
