Problems solved by technology

[0005] The misconnection of the interface adapter of the test equipment is mainly reflected in: there are interface adapters and test cables with the same shape and size in the general test equipment, and the wrong plugging phenomenon caused by the test personnel ignoring the equipment identification, etc.

Embodiment

[0050] Code and paste QR codes on all missile products under test, and code and paste QR codes on both ends of the test cable connector and the interface adapter end of the test equipment. Before the missile test, the testers first hold the scanning device to scan the QR code on the tested missile product and the test cable, and the scanned information is immediately returned and stored in the QR code information database installed on the test industrial computer. The error prevention and error discrimination software of the test industrial computer reads the information content of the two-dimensional code, gives the judgment conclusion of whether there is an error, and displays it in the software interface.

[0051] Before the official missile test begins, the testers follow the figure 2The flow chart of the system operation is shown, and the anti-error inspection is carried out. Complete the QR code scanning verification of the missile product under test, the test equipmen...

Abstract

The invention provides an error prevention system and method for missile testing equipment, comprising: a two-dimensional code judging module, a resistance judging module, a digital I / O judging module, a PXI board assembly, a judging module, and a testing industrial computer. The present invention combines two-dimensional codes, resistance value identification, and electronic ID identification, aiming at problems such as confusion of the tested missile product, wrong connection of test cables, and test equipment interface adapters that are most likely to occur due to human errors during the testing process of missile products. Establish an anti-error system from the missile product under test to test cables, interface adapters and error-proof test software. Compared with the previous method of relying on manual inspection, the automatic program is used to detect errors from the product end to the test equipment end, which can effectively avoid failures caused by human errors and improve test safety.

Description

technical field [0001] The invention relates to the technical field of automatic measurement and control, in particular to a system and method for error-proofing a product terminal under test, a test cable, a test equipment interface adapter and test software during a missile test. Background technique [0002] During the use and maintenance of multi-type general-purpose automated test equipment for air defense missiles, failures or accidents may occur due to misoperation by personnel or system operation errors, such as plugging in wrong interface adapters, test cables, etc. These accidents are often easy to cause damage to the product under test and bring about a large impact loss. Among them, human error is the main factor considered in the error prevention design of test equipment. In the process of using general-purpose test equipment, human errors are mainly manifested in several aspects such as confusing the tested missile product, wrongly connecting the test cable, a...
