Problems solved by technology

[0004] At present, the research on expressway master data in the industry is still immature, and a complete expressway master data management process has not yet been formed, and the establishment of master data standards is the prerequisite for realizing master data management; therefore, to realize the large-scale application of big data technology in expressways application, it is urgent to identify master data from the huge expressway data resources and establish a standard system for expressway master data to ensure the unity and standardization of expressway master data. Provide a good data base

specific Embodiment II

[0103] Specific embodiment II: take the expressway of province A as an example to carry out the master data identification described in the present invention.

[0104] First, we analyze the key business of expressway operation in province A, and combine the opinions of business experts to obtain the fuzzy complementary judgment matrix A as follows:

[0105]

[0106] According to the formula (6), the matrix A is calculated, and the weight vector Z of each evaluation index is obtained as:

[0107] Z=(0.167,0.150,0.152,0.117,0.133,0.148,0.133) (12)

[0108] The characteristic matrix Z of this weight vector is calculated by the weight vector Z according to the formula (9) * for:

[0109]

[0110] Then according to the obtained weight vector feature matrix Z * Compatibility judgment with the fuzzy complementary judgment matrix, I(A,Z) can be obtained from the formula (7) * )=0.132≤0.2, conforming to the compatibility judgment, indicating that the fuzzy judgment matrix has...

Abstract

In order to overcome the defects in the prior art, the invention provides a main data acquisition method and system, and the method comprises the steps: obtaining a main data evaluation index according to the characteristics of a target scene; constructing a fuzzy analytic hierarchy process model to obtain a main data identification model; and identifying data in a target scene through the main data identification model to obtain main data in the target scene. According to the method, a main data evaluation index is obtained according to the characteristics of the target scene, and then a main data identification model is obtained on the basis of constructing a fuzzy analytic hierarchy process model; and finally, data in the target scene are identified through the main data identification model to obtain main data in the target scene.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a method, a system, an electronic device and a computer-readable storage medium for acquiring master data of an intelligent expressway. Background technique [0002] At present, some companies have designed and implemented unique data coding platforms in the power grid, automobile, petroleum, steel, insurance, communication, tobacco and railway industries based on the characteristics of their respective industries and the in-depth study of the group's system. Or master data management system, which improves the management level of enterprise master data. For this reason, the present invention combines the functional requirements of the smart expressway business system in province A to study a set of effective methods for the standardization of expressway master data, laying a solid foundation for the efficient management of expressway master data.
