Train running state data analysis method and system and rail transit vehicle

Abstract

The invention discloses a train running state data analysis method and system and a rail transit vehicle. The method comprises the following steps: converting a train-ground transmission protocol document into a table file, importing the table file into a database, and generating a corresponding analysis coding rule for a signal in each protocol in the table file; analyzing and exporting data in the database by utilizing the analysis coding rule, and configuring a display rule to obtain a configuration table; importing the configuration table into the database; in the analysis process of the vehicle real-time data, a database is inquired, and an analysis coding rule is obtained; and analyzing the vehicle real-time data according to the analysis coding rule, and displaying the real-time running state of the vehicle according to a display rule. Configuration and adaptation of train-ground transmission protocols of different train types and different versions of train-ground transmissionprotocols of the same train type can be achieved, configuration of train operation state display is achieved, the efficiency of train operation state data monitoring dynamic display is improved, and the manual workload is reduced.

Description

technical field [0001] The invention relates to the technical field of train monitoring, in particular to a method and system for analyzing train running state data. Background technique [0002] With the continuous development of urban rail transit, higher requirements are put forward for the safety of train operation. In the prior art, by using the vehicle-ground transmission equipment configured on the train to collect, process and send the real-time operation data of the vehicle, the ground system receives and analyzes the real-time operation data sent by the vehicle-ground transmission equipment and monitors the real-time operation status of the train. The demonstration shows that it can effectively monitor the real-time running status of the train and improve the operational safety of the train. [0003] However, trains of different models have different vehicle-to-ground transmission protocols, and the same vehicle-to-ground transmission protocol also has different v...

Problems solved by technology

[0003] However, trains of different models have different vehicle-to-ground transmission protocols, and the same vehicle-to-ground transmission protocol also has different versions, which makes the analysis of real-time train running status data extremely complicated. It shows that the delay requirement is extremely high, and the separate programming and analysis of the protocol becomes complicated and time-consuming, which will affect the efficiency

At the same time, the different operating data of different models and the different train operating status data displayed in the train HMI system require that the train operating status data displayed by the ground train monitoring system is also different, and the train operating status information already displayed by the train monitoring system should be adjusted. also extremely inconvenient

Therefore, it is difficult to configure and adapt different versions of the vehicle-to-ground transmission protocol of different models, and different versions of the same vehicle-to-ground transmission protocol, and it is impossible to realize the unified configuration of train operation status data display. New protocols and protocol version upgrades need to modify the code, and the ground display and vehicle display longer delay
