The checking system is a software system for assisting a user in performing active message checking, and checks messages with different contents by taking a scene as a unit.

The checking system comprises several functional parts:

1) and (3) scene classification: and subdividing all messages into ten different scenes according to the difference of sending conditions for checking, and ensuring that the message checking coverage rate reaches 100%.

2) And (3) auxiliary test design: in the stage of designing the test case, the manual work is completely replaced to complete all work of calculating the summarized data, the efficiency is higher, the accuracy is higher, and a design case initial table, a summary table of various data conditions and related data for a user to compile the test case are output.

3) Checking the message: the message content is intelligently checked according to the application principle and the engineering data, the process is completely and automatically completed by the system, the checking result is not interfered by the user service capacity, the calculation accuracy and the external conditions, and the user can check the data calculation step during checking and obtain the final checking conclusion.

According to the invention, through long-term and massive experience summarization of a work flow of message checking, and by combining related documents (such as technical conditions of TB T3439-2016 column control center, notification of general iron [2014]246 China railway company about printing of a temporary method for managing column control data, and the like), the whole active message checking work is systematically divided into ten scenes, and in order to further optimize the work flow and reduce the time consumption in the work connection process, each scene (the checking work) is further divided into two implementation stages:

(1) a design stage: after the user inputs engineering data, different types of forms for assisting the user in designing the test case are respectively generated according to different requirements of each scene, wherein the forms mainly comprise the following contents: items required to be checked in the scene, the overall situation combing of the station information, various types of calculation data required in case design, design forms of test message cases and the like.

(2) And (3) checking: a virtual coordinate system is formed internally according to engineering data, the corresponding position relation between each element (such as a transponder, an annunciator, a station and the like) is determined, then an initial version message is formed according to an application principle and various standard methods, finally the message in the TCC is compared with the calculation initial version message, and various compatible data differences are automatically processed in the comparison process.

After the active message checking works in a selected scene, firstly, a test case under the scene needs to be designed, and the system automatically calculates according to the message characteristics of the scene and by combining engineering data: data and initial version design tables which may need to be used when all the design cases are used for users to refer; the application principle is integrated into the checking system in an algorithm mode, and corresponding terms (from the application principle and various specifications) are automatically used for verifying the correctness of each field value in the message and processing compatible differences among a plurality of manufacturers when the message is checked.

Various designs of the checking system are carried out with the fundamental purposes of high efficiency, intellectualization, high precision and labor cost saving. In the design stage of designing the test case, in order to save the time for manually calculating data and improve the accuracy of the data, the system automatically calculates all data which originally need to be manually calculated, for example, all track sections and speed-limiting sections need to be arranged and combined together and the values such as length and the like need to be calculated manually, the system can automatically complete the arrangement and calculation process at present, and a user only needs to use an output result; in order to save manpower, reduce the service threshold of the checking personnel and improve the checking accuracy in the checking stage of the message, the checking system embeds the application principle into the message, so that a non-professional user can normally use the message, for example, the original user needs to calculate the description range of the message according to the application principle and judge whether a plurality of groups of data can be combined, the algorithm is written into the system, and the user only needs to check the calculation process and the checking result.

After receiving the new version of TCC software, the message checking personnel of the road bureau checks all the messages stored in the message checking personnel, and the system subdivides the whole work into ten scenes in order to ensure that the message checking is not omitted, so that all the messages can be completely covered by the ten scenes. Referring to fig. 1, the ten scenarios are:

(1) TSRS initialization-CBI inbound signal opening

(2) TSRS init-siding through trailer

(3) TSRS initialization-positive line speed limit

(4) TSRS initialization-lateral speed limit (in station)

(5) TSRS initialization-CBI in-out signal closing

(6) TSRS init-CBI fault

(7) TSRS uninitialized-CBI inbound signal open

(8) TSRS uninitialized-CBI in-out signal closing

(9) TSRS uninitialized-CBI failure

(10) Shunting device

The checking work is carried out only according to the scene classification, all (needing to be checked) messages can be completely covered, the independence of each scene can ensure that a plurality of people work in parallel, and the defect that single-thread work consumes long time is eliminated. The road bureau can only check the messages under partial scenes according to the actual needs of the road bureau.

The checking system further optimizes the existing flow on the basis of summarizing the defects of the working flow of the past message checking, and divides the message checking work under each scene into two stages, namely a design stage (test case design) and a checking stage (field value checking in the message), which are shown in figure 2.

The system is used for assisting a user in designing test cases, the user inputs engineering data, the system replaces manual work, automatically calculates all data required by designing the test cases, generates data integral condition carding at the same time, enables the user to master the data condition from a macroscopic view, and outputs the content mainly comprising route types, link relations, data ranges, route numbers, items required to be verified through routes, corresponding relations between speed-limiting sections and track sections, primary speed-limiting design tables of main lines and lateral lines calculated according to the principle and the like. Compared with the existing working mode, the form forming time, the data calculating time and the personnel business culture time consumed by the user at the stage can be basically ignored.

In the checking stage, a user inputs engineering data, a message to be checked and a design example table (optional), the system forms an initial version message according to the application principle after forming an internal virtual coordinate system according to the engineering data, then compares the messages of different manufacturers with the initial version message, intelligently processes compatible problems of merging of various sections, dissimilarity processing of different manufacturers and the like, the checking content mainly comprises checking of message structures, description ranges and field values, and finally, comparison results are summarized according to classification to form a report table for output. The user does not need to check the principle and switch the calculation values line by line among the tables, the system can automatically complete all the work, all the calculation processes are transparent and visible, and the user can check the calculation values at any time.

The user can select proper data from the table in fig. 3B to fill in the table in fig. 3A according to the test requirement.

And (3) checking: after a user selects a corresponding scene, a message, engineering data and a design case table are input, the system generates other information packets except a speed limit information packet according to the engineering data and an application principle, then generates the speed limit information packet according to corresponding information in the design table, matches the corresponding message according to a file name after the whole generation is finished, compares the speed limit information packet and the corresponding message, combines the speed limit information packet and the corresponding message with different manufacturers in the comparison process, and finally classifies, summarizes and outputs results in a grading way.
