Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The railway metrology technology authority manages the special metrology instruments for the entire railway. It needs to remotely monitor the metrology and calibration process of metrology and calibration stations located in various places in real time. This involves the transmission of process data and result data with high real-time, high reliability and high convenience. Using QR code to transmit and store data is a reasonable choice.

[0028] A QR code is a black and white graphic that records data symbol information using certain specific geometric shapes distributed in a plane according to a certain pattern. It has the characteristics of large information capacity, wide coding range, strong fault tolerance, high decoding reliability, low cost, easy production, durability and convenience of use. Therefore, it is widely used in product traceability and anti-counterfeiting, marketing promotion, mobile payment, ticketing services, social sharing and other occasions.

[0029] Therefore, the embodiment of the present application provides a method for measuring and verifying the readings of a track inspection device. The method is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, Figure 1 As shown, the method includes the following steps.

[0030] S1: Generate a QR code from the metrological verification data of the track inspection equipment according to a preset format and display it on a graphical user interface; the preset format includes the inspection unit, manufacturer, model specification, factory number, accuracy level, time, verification ambient temperature, verification date, multiple verification items i, verifier and checker, where i=1,...,N; the QR code includes a total QR code and several sub-QR codes; the total QR code is used to represent the metrological verification table of the track inspection equipment generated according to the preset format, and the several sub-QR codes are used to represent the metrological verification data of the track inspection equipment in the metrological verification table of the track inspection equipment.

[0031] S2: Instruct the metrology verification agency to synchronously read the QR code according to the metrology verification specification requirements.

[0032] S3: Automatically decode the two-dimensional code to determine the decoded measurement and verification data of the track inspection equipment.

[0033] In an exemplary embodiment, S1 may be replaced by the following steps.

[0034] S11: Generate a total two-dimensional code including all fields according to the measurement and verification data of the track inspection equipment.

[0035] S12: Divide the track inspection equipment metrology and verification data into a number of sub-fields according to the set field redundancy, and generate a sub-QR code corresponding to each sub-field.

[0036] Furthermore, the two-dimensional code system may be QR Code, PDF417, Code 49, Code 16K or Code One, etc.

[0037] The preset format of the data complies with the requirements of JJG1090 and TB / T3147, and should include the following fields: "Inspection unit, manufacturer, model specification, factory number, accuracy level, time, calibration environment temperature, calibration date, calibration item 1,..., calibration item N", and several reserved fields can be set.

[0038] Figure 2 FIG. 1 is a schematic diagram of a simple rail inspection equipment measurement and verification reading system in an embodiment of the present application. Figure 2 As shown, during the process of metrological verification of track inspection equipment such as track inspection instruments and rapid track inspection instruments, the relevant data is displayed on the graphical user interface 1. At the same time, the relevant data is encoded into a total QR code 2 and several sub-QR codes 3 using QR code encoding software, and displayed in a specific area of ​​the graphical user interface 1.

[0039] like Figure 3 As shown, the data related to the metrological verification of track inspection equipment include fields such as "inspection unit, manufacturer, model specification, factory number, accuracy level, time, verification ambient temperature, verification date, verification item 1, ..., verification item N, verifier, checker" and so on.

[0040] Static codes are used to transmit process data of metrological verification, and the code system can be QR code.

[0041] A total QR code containing all fields is generated from the measurement and calibration data of the track inspection equipment; the measurement and calibration data of the track inspection equipment is divided into four sub-fields: "calibration platform superelevation indication h10, track inspection instrument forward indication h1", "track inspection instrument forward indication h1, track inspection instrument reverse indication h2", "track inspection instrument reverse indication h2, indication error" and "calibration platform superelevation indication h10, indication error". There is redundancy between the fields, and four corresponding sub-QR codes are generated.

[0042] In an exemplary embodiment, S2 may be replaced by the following steps.

[0043] S21: using a collection device to collect the two-dimensional code in real time, and synchronizing the two-dimensional code to a metrology and verification agency through a network using a dynamic code or a static code.

[0044] Furthermore, the total QR code and the sub-QR code are read synchronously; dynamic code or static code is used to transmit process data or result data of metrological verification.

[0045] In an exemplary embodiment, S3 may be replaced by the following steps.

[0046] S31: Instruct the metrology verification organization to use a code reader to scan the total QR code and each sub-QR code respectively, and decode the total QR code and each sub-QR code according to the preset format to generate decoding data; the decoding data includes total QR code decoding data and sub-QR code decoding data.

[0047] S32: Verify the decoded data, and use the decoded data that passes the verification as the decoded track inspection equipment metrology verification data.

[0048] In an exemplary embodiment, S32 may be replaced by the following steps.

[0049] S321: Determine whether the decoded contents of the total two-dimensional code decoded data are consistent with the decoded contents of the sub-two-dimensional code decoded data. If so, execute S322; if not, execute S323.

[0050] S322: Determine whether the decoded data verification passes.

[0051] S323: Determine the decoding data with the highest appearance frequency among the total two-dimensional code decoding data and the sub-two-dimensional code decoding data, and select the decoding data with the highest appearance frequency as the decoding data.

[0052] Take two sub-QR codes as an example: a field in the total QR code decoded data displays 0.25, a field in the first sub-QR code decoded data displays 0.26, and a field in the second sub-QR code decoded data displays 0.25. Therefore, the decoded data with the highest frequency is 0.25. Therefore, 0.25 passes the verification and the data is filled in with 0.25.

[0053] Furthermore, the metrology verification agency uses a code reader to scan the total QR code and decodes the data according to a preset format; the metrology verification agency uses a code reader to scan each sub-QR code and decodes the data according to a preset format; verifies the decoded data; and confirms and stores the data that passes the verification.

[0054] In practical applications, such as Figure 2 As shown, a network camera 4 or other equipment can be used to collect the total QR code 2 and the four sub-QR codes 3 in real time, and the images of the total QR code 2 and the four sub-QR codes 3 can be synchronously uploaded to the computer 6 of the metrology verification agency through the network 5.

[0055] The metrology verification agency uses a code reader 9 to scan the total QR code 7 on the graphical user interface of the computer 6, and decodes the data according to a preset format; the metrology verification agency uses a code reader 9 to scan each sub-QR code 8 on the graphical user interface of the computer 6, and decodes the data according to a preset format; verifies the decoded data; and confirms and stores the data 10 that passes the verification.

[0056] like Figure 4As shown, the metrology verification agency uses the code reader 9 to scan the total QR code 7 on the graphical user interface of the computer 6, and decodes the data according to a preset format; the metrology verification agency uses the code reader 9 to scan and decode the four sub-QR codes 8 on the graphical user interface of the computer 6, and decodes the data according to a preset format; the decoded data is verified, and if the decoded contents of the total QR code 7 and the sub-QR code 8 are consistent, the verification is passed; if they are inconsistent, the decoded data with the highest frequency of occurrence between the total QR code decoded data and the sub-QR code decoded data is determined, and the decoded data with the highest frequency of occurrence is selected; the data 10 that passes the verification is confirmed and stored.

[0057] In practical applications, the track inspection equipment includes a level 1 track inspection instrument, a level 0 track inspection instrument, a fast track inspection instrument, and the like.

[0058] This application uses QR codes to record and transmit the metrological and calibration data of track inspection equipment. Only a small number of changes need to be made to the graphical user interface of the workbench. It has good data reliability and transmission convenience, low technical difficulty, and is convenient and practical. It helps to achieve remote real-time acquisition of metrological and calibration data of track inspection equipment with high real-time performance, high reliability and high convenience.
