Problems solved by technology

The navigation-specific test equipment generally has no national or industry regulations for specific navigation test equipment. The existing practice is that the measurement personnel calibrate according to the technical specification of the equipment, and the test items given in the specification are generally from the manufacturer of the equipment. The main components and functions are sorted out, and most of them are circuit-level test items, and their test items are not completely suitable for the requirements of measurement
[0003] According to the existing measurement methods, the calibration cycle required to calibrate a special navigation test equipment is long and covers a wide range of specialties, which requires high requirements for the measurement laboratory

Embodiment 1

[0030] The present invention is realized through the following technical solutions, as figure 1 As shown, a method for determining the priority of calibration items for navigation-specific test equipment is to classify relevant files for navigation-specific test equipment, sort out keywords, use the classified related files and keywords to match, and sort out A collection of item numbers; logical operations are performed on the item collection to obtain priority calibration items in turn.

[0031] It should be noted that, through the above-mentioned improvements, the purpose of the present invention is to improve the measurement status quo that the calibration items of the current navigation-specific test equipment are not suitable for measurement characteristics, the calibration period is long, and the professional requirements of the metrology laboratory are high, and a new navigation-specific test equipment is proposed. The method of prioritizing the calibration items, so a...

Embodiment 2

[0035] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, it specifically includes the following steps:

[0036] Step F1: For the navigation-specific test equipment, filter out the files related to the navigation system that are similar to the equipment test items, and classify the screened files according to industry standard files and non-standard files, and then classify the industry standard files into Industry management standard documents and industry technical standard documents;

[0037] Step F2: For the special navigation test equipment, through its technical specification and actual calibration experience, analyze the actual function of its test items, and sort out the calibration items that meet the measurement performance requirements as keywords;

[0038] Step F3: According to the keywords sorted out and the documents screened out, carry out keyword search and matching according to the document clauses, and reco...

Embodiment 3

[0047] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, 3. The step F1 specifically includes the following steps:

[0048] Step F11: According to the instructions of the special navigation test equipment, analyze its test function, and filter the international and domestic documents related to navigation to find the documents with the same or similar test functions as the special navigation test equipment;

[0049] Step F12: Reclassify the selected files with the same or similar test functions as the special navigation test equipment; divide them into industry standard files and non-standard files;

[0050] Step F13: Divide the industry standard files into industry management standard files and industry technical standard files.

[0051] The industry standard documents include international civil aviation manuals and civil aviation management documents; the non-standard documents include customer requirements, related pape...

Abstract

The invention discloses a method for determining priorities of calibration items of special test equipment for navigation. Aiming at the special test equipment for navigation, related files are classified, keywords are sorted out, matching is carried out by using the classified related files and keywords, and a set of item numbers is sorted out; and logical operation is carried out on the item set, so that the calibration items with the priorities are obtained in sequence. Test items in a description of the special test equipment for navigation are converted into the calibration items with thedistinguished priorities, and metering items and circuit-level test items are separated, so that index requirements of the calibration items can be combined with industrial standard files or user requirements, a calibration result is more reliable, the calibration time is greatly shortened, and a reference can be provided for metering laboratories to select the calibration items of the special test equipment for navigation.

Description

technical field [0001] The invention relates to the technical field of metrology, in particular to a method for determining the priority of calibration items of navigation-specific test equipment. Background technique [0002] In the field of metrology, navigation-specific test equipment refers to those equipment that can only test navigation systems or equipment, or those non-universal test equipment used for special purposes. The measurement of navigation special test equipment is different from that of general test equipment. General test equipment generally has national or industry measurement regulations as the basis for measurement, and measurement personnel can complete the traceability of general test equipment according to the measurement items of the corresponding regulations. The navigation-specific test equipment generally has no national or industry regulations for specific navigation test equipment. The existing practice is that the measurement personnel calibr...
