Description

Multisource monitoring system for rail transit monitoring items Technical Field The invention belongs to the technical field of engineering data monitoring, and particularly relates to a multisource monitoring system for rail transit monitoring items. Background Along with the continuous increase of track traffic, deep foundation pits, construction of adjacent business lines and underground engineering monitoring projects, the on-site monitoring system usually simultaneously comprises a total station, a static level gauge, an inclination sensor, a displacement meter, a water level meter, a crack meter, a manual measuring terminal and other devices, and is respectively managed by platforms of different manufacturers or on-site acquisition programs. The above devices differ significantly in field definition, unit architecture, timestamp format, coordinate references, communication protocols, sampling frequency and quality constraints, resulting in lower efficiency of multi-source data access, alignment, sharing and supervision linkage. In the prior art, common practice is to collect multi-source data through a universal data access platform or a single manufacturer platform, complete format conversion, time alignment and coordinate conversion by combining with an artificial script, and perform asset registration, approval circulation and authority configuration in a subsequent management system. The method can meet the basic requirements of 'being accessed, displayed and derived' to a certain extent, but has the following problems that firstly, most systems take time alignment and space alignment as preprocessing steps, lack of linkage constraint of topological relation with engineering working procedures and monitoring objects, so that the situation of 'form alignment and semantic dislocation' of data of the same measuring point under different working conditions is easy to occur, secondly, the existing data asset management is usually classified and circulated towards a general data set, quality evidence, alignment basis, equipment fingerprints and parameter versions in the process of monitoring data access management are difficult to integrate and package, so that verifiability and traceability after delivery are insufficient, thirdly, when a general platform is directly applied to a track traffic scene, only interface or field adaptation is adopted, track traffic engineering constraints such as a line, an interval, a working point, a component, a measuring point, mileage coordinates and a working procedure stage are not converted into rule constraint of a method per se, and stable engineering closed loops are difficult to form. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a multi-source monitoring system for track traffic monitoring items, which can embed topological structures, mileage coordinate systems and process stage constraints in track traffic monitoring scenes into real-time access, asset packaging and transfer delivery processes, improves access reliability, asset verifiability and delivery controllability of multi-source monitoring data, solves core pain points of data isomerism, unreliability, difficult traceability, high risk and high cost in track traffic monitoring, and realizes the reliable and controllable full life cycle of data from acquisition to delivery.
