Operation data acquisition method and operation data acquisition system for trains

Abstract

The invention provides an operation data acquisition method and an operation data acquisition system for trains. The method includes by a data gateway, acquiring a data packet from an acquisition terminal, and sending the data packet to message queue middleware; by the message queue middleware, extracting identification codes of the acquisition terminal from the data packet, and storing operationdata in the data packet into message queues corresponding to the identification codes, wherein the different identification codes correspond to the different message queues; when the operation data are data focused by a data center, sending the operation data to the data center by the message queue middleware. An efficient and reliable message transmission mechanism of the message queue middlewarecan be utilized in the method, the operation data can be efficiently and reliably transmitted to the data center, and the data integrity is guaranteed. In addition, the data center only receives thedata of its own interest, so that the data processing efficiency of the data center is improved, and the system reliability is ensured.

Description

technical field [0001] The invention relates to the technical field of train communication, in particular to a method and system for collecting train operation data. Background technique [0002] Trains are the main body of rail transit. Accurately collecting and processing train running data in real time is a basic requirement for rail transit operations. In the prior art, the collection terminal is directly connected to the data center, and the data center obtains the current running data of the train from the collection terminal and processes the current running data. [0003] In the actual application scenarios of rail transit, multiple trains are often running on each line at the same time. At this time, there will be a large amount of concurrent data that needs to be reported to the data center at the same time. When the data center processes a high amount of concurrent data, it often occurs The problem of insufficient processing capacity makes it difficult to ensure ...

AI Technical Summary

Problems solved by technology

In addition, the data center only receives the data that it is interested in, thereby improving the efficiency of data processing in the data center and ensuring the reliability of the system, so as to solve the problem of running multiple trains on each line at the same time in the prior art. There is a large amount of concurrent data that needs to be reported to the data center at the same time, and when the data center handles a high amount of concurrent data, it often has the problem of insufficient processing capacity, which makes it difficult to ensure the reliability of rail transit

In addition, when the network is unreliable, it is easy to cause data loss
