In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0042] To solve the problems in the background art, embodiments of the present disclosure provide a train virtual marshalling key technology test requirement extraction method and device. Specifically, various running data of train virtual marshalling running are acquired; the various running data are matched with various train virtual marshalling key technologies to determine the train virtual marshalling key technologies corresponding to the various running data; the various running data are divided into a first data set of the train virtual marshalling key technologies corresponding thereto; and test requirements of the various train virtual marshalling key technologies are generated according to the running data in the first data set of the various train virtual marshalling key technologies.

[0043] In this way, the attribution of various operation data can be divided by matching various operation data at train virtual marshalling running time with various train virtual marshalling key technologies, and then the test requirements of various train virtual marshalling key technologies are generated, the systematic extraction of the test requirements of train virtual marshalling key technologies is realized, and the actual engineering application effect of train virtual marshalling key technologies is improved.

[0044] The train virtual marshalling key technology test requirement extraction method and device provided by the embodiments of the present disclosure will be described in detail below with reference to the specific embodiments combined with the accompanying drawings.

[0045] Figure 1 A flowchart of a train virtual marshalling key technology test requirement extraction method provided by an embodiment of the present disclosure is shown in FIG. 1. Figure 1 As shown in FIG. 1, the train virtual marshalling key technology test requirement extraction method 100 can include the following steps:

[0046] S110, obtaining various operation data at train virtual marshalling running time.

[0047] The operation data can include but is not limited to: marshalling train running speed, marshalling train interval, marshalling train station running interval, marshalling train communication delay, marshalling train station stopping time difference, marshalling train station departure time difference, marshalling train station stopping accuracy, etc.

[0048] S120, matching various operation data with various train virtual marshalling key technologies to determine the train virtual marshalling key technologies corresponding to various operation data.

[0049] Exemplarily, the various operation data can be judged according to the index parameter judgment conditions of various train virtual marshalling key technologies to determine the index parameter judgment conditions met by various operation data.

[0050] The train virtual marshalling key technologies can include: train virtual marshalling safety protection technology, train virtual marshalling cooperative control technology and other train virtual marshalling key technologies; the index parameter judgment condition is used to judge whether the operation data is the index parameter required by the corresponding technology.

[0051] For any kind of operation data, the train virtual marshalling key technology corresponding to the index parameter judgment condition met by the operation data is determined as the train virtual marshalling key technology corresponding to the operation data.

[0052] In this way, the index parameters of various train virtual marshalling key technologies can be determined according to the index parameter judgment conditions of the various train virtual marshalling key technologies, and then the train virtual marshalling key technologies to which the various operation data belong can be effectively determined.

[0053] In S130, the various operation data are divided into the first data set of the corresponding train virtual marshalling key technology.

[0054] In S140, the test requirements of various train virtual marshalling key technologies are generated according to the operation data in the first data set of the various train virtual marshalling key technologies.

[0055] In some embodiments, for the first data set of any train virtual marshalling key technology, the operation data in the first data set can be matched with various technical elements of the corresponding train virtual marshalling key technology, the technical elements to which the various operation data in the first data set belong are determined, i.e., the technical elements to which the various operation data in the first data set belong are determined, and then the various operation data in the first data set are divided into the second data set of the corresponding technical element.

[0056] The technical elements are important components of the train virtual marshalling key technology. For example, the technical elements of the train virtual marshalling safety protection technology include but are not limited to: basic safety parameters, intermediate variables, final safety results, and other safety functions; the technical elements of the train virtual marshalling cooperative control technology include but are not limited to: target reference curve, tracking control algorithm, etc.

[0057] According to the operation data in the second data set of the various technical elements of the corresponding train virtual marshalling key technology, the test requirements of the various technical elements are generated and are taken as the test requirements of the corresponding train virtual marshalling key technology.

[0058] For example, for the second data set of any technical element of the corresponding train virtual marshalling key technology, the test items corresponding to the various operation data in the second data set can be generated according to the operation data in the second data set, wherein the test items can include: number, content, parameter, verification object, etc., and then the test requirements of the corresponding technical element are quickly generated according to the various test items generated, and then the test requirements of the various technical elements of the corresponding train virtual marshalling key technology are taken as the test requirements of the corresponding train virtual marshalling key technology.

[0059] In this way, the operation data can be further divided into the second data set of the technical elements of the train virtual marshalling key technology based on the first matching, and then the test requirements of the various train virtual marshalling key technologies are generated in a more detailed manner.

[0060] In some other embodiments, if the train virtual marshalling key technology is a designated train virtual marshalling key technology, the operation data in the first data set of the train virtual marshalling key technology can be matched with various technical elements of the train virtual marshalling key technology, the technical elements corresponding to various operation data in the first data set are determined, and then various operation data in the first data set are divided into the second data set of the corresponding technical elements. According to the operation data in the second data set of various technical elements of the train virtual marshalling key technology, the test requirements of various technical elements are generated and used as the test requirements of the train virtual marshalling key technology.

[0061] If the train virtual marshalling key technology is not a designated train virtual marshalling key technology, the test requirements of the train virtual marshalling key technology are directly generated according to the operation data in the first data set of the train virtual marshalling key technology.

[0062] In this way, the overall efficiency of test requirement extraction can be improved while generating the test requirements of the designated train virtual marshalling key technology in a more refined manner.

[0063] In the embodiments of the present disclosure, the attribution of various operation data can be divided by matching the various operation data during the train virtual marshalling with various train virtual marshalling key technologies, and then the test requirements of various train virtual marshalling key technologies are generated, the systematic extraction of the test requirements of the train virtual marshalling key technology is realized, and the actual engineering application effect of the train virtual marshalling key technology is improved.

[0064] It is worth noting that after S140, the train virtual marshalling key technology test requirement extraction method 100 can further include:

[0065] The test items in the generated test requirements of various train virtual marshalling key technologies are valued, for example, the test items in the generated test requirements of various train virtual marshalling key technologies are quickly valued according to the index parameters (i.e. theoretically calculated parameter values) of various train virtual marshalling key technologies.

[0066] According to the valued test requirements, a train virtual marshalling key technology test requirement list is generated, which is used as a guide for train virtual marshalling key technology testing.

[0067] In this way, the test cost and test cycle of the train virtual marshalling key technology can be reduced, and the test efficiency of the train virtual marshalling key technology can be improved. In addition, the train virtual marshalling key technology testing can be more targeted and accurate, effectively reducing the errors and risks in technical research and actual application, providing important support and guidance for the research of train virtual marshalling technology, and promoting the innovation and development of train virtual marshalling technology.

[0068] It can be understood that, in order to make the train virtual marshalling key technology test requirement list more in line with the actual situation of the train virtual marshalling key technology, the corresponding test case can be generated according to the test requirements in the generated train virtual marshalling key technology test requirement list, and the test case is executed, and according to the execution result of the test case, the value of the test item in the corresponding test requirement is optimized and adjusted.
