Description

Version management, line acquisition and message verification method for RBC data Technical Field The present disclosure relates to rail transit technologies, and in particular, to a method for version management, line acquisition, and message verification of RBC data. Background In a railway signaling system, a radio block center (Radio Block Center, RBC) acts as a critical train control device, the operation and testing of which relies on a series of basic data with complex correlations. These data typically exhibit multi-level, multi-version features that are difficult to manage. In the prior art, complex version association tables are relied on to record and maintain the association relationship between data items. This approach attempts to preserve the historical relevance of the data, but as versions iterate frequently, the data hierarchy increases, resulting in a dramatic increase in database storage costs. More importantly, the complex association relation is easy to be confused, inconsistent or broken in the continuous updating and maintaining process, and the data integrity and reliability are difficult to guarantee. The second scheme is to directly perform full overwrite writing on the target data at the time of version update. This approach, while simple to operate, thoroughly destroys the historical state of the data, making it impossible to trace back and reproduce any historical version. Meanwhile, in a complex multi-layer data context, the rough updating mode is extremely easy to cause data inconsistency or conflict across layers, and potential risks are brought to stable operation of the whole system.
