Description

Technical Field

[0001] The invention belongs to the technical field of construction inspection of four-electricity interfaces, and specifically discloses an information-based railway four-electricity interface inspection and construction method. Background Art

[0002] As a key component of high-speed railway technology, the four electrical interfaces are generally inspected manually on-site during construction. However, they have the following defects: 1. Existing inspection methods usually rely on two-dimensional drawings, which makes it impossible to intuitively feel the overall layout of the project and the location of the interfaces. Inspection is difficult, information acquisition speed is slow, and there are high requirements for the professionalism of inspectors. 2. In view of the wide variety of interfaces and the large differences between the four electrical professions, a large number of professional and technical personnel are required for the early inspection. However, due to the single form of training in existing technologies, which mainly rely on paper materials and on-site explanations, the training effect is limited, the training cycle is long, and it cannot meet the needs. 3. Existing inspection methods rely on manual analysis and processing of data. In terms of data management, there are problems such as inconvenient on-site information verification and recording, unclear inspection technical standards, non-standard management processes, non-closed-loop problem rectification, unclear process traces, inconvenient information query, incomplete data summary and analysis, and unclear improvement direction.

The four electrical interfaces inspection process is initiated simultaneously online and offline. Offline inspections are conducted in a three-party joint inspection system. Online inspections are conducted on the information management platform, using standardized inspection content and record forms as the basis, creating a customized closed-loop management process for the four electrical interfaces engineering inspections.

Inspectors can conduct inspections according to unified standards, avoiding the differences caused by unclear standards. By customizing the full closed-loop management process, each link of the interface inspection is standardized. From the initiation of the inspection task to the handling of the problem, to the final confirmation of the sale, each link has a clear process and person in charge to ensure the standardization of the management process. Online data is automatically archived so that every operation and data in the inspection process can be recorded. The quality common problem analysis unit 32 is used to summarize the quality common problems of the four-electric interface project, analyze the causes, and formulate refined construction process quality control points to avoid the recurrence of similar problems and provide a clear direction for project improvement.
