Cloud-based rail transit multi-bus data analysis system

Abstract

The invention discloses a cloud-based rail transit multi-bus data recording and analyzing system, and belongs to the field of maglev, subway and other rail transit vehicles, wherein the system comprises a data recording and analyzing instrument and a cloud server; the data recording and analyzing instrument is used for acquiring real-time data and accumulated data of a normal state and a fault state in the running process of a rail transit train; the cloud server is used for receiving the real-time data and accumulated data, transmitted by the data recording and analyzing instrument, of the normal state and the fault state of the train in the running process, storing faults occurring in the running process of the rail transit train in real time and carrying out fault analysis and diagnosis, wherein the cloud server transmits a fault analysis and diagnosis result back to the data recording and analyzing instrument, and the data recording and analyzing instrument transmits a diagnosis result and a processing measure of the cloud server to a train bus; a fault prediction mode of the cloud server has a real-time fault analysis capability; program upgrading and equipment health state detection of the data recording and analyzing instrument can be remotely realized by the system, so that investment of manpower and material resources can be reduced.

Description

technical field [0001] The invention relates to the field of rail transit vehicles such as maglev, subway, and light rail, and in particular to a cloud-based rail transit multi-bus data analysis system. Background technique [0002] With the rapid development of the rail transit field, the operation data of the train in the whole life cycle has not been reasonably analyzed and utilized. These data can provide important data support for train operation maintenance and fault diagnosis. [0003] The train backbone network of rail transit is composed of the sub-network and maintenance network of each train, and several network relay devices realize the signal relay and interference isolation functions. The train maintenance subnet is composed of the equipment that the train needs to maintain, the maintenance switch and the train-to-ground wireless transmission unit, and realizes the purpose of maintaining the vehicle equipment locally or remotely; the train subnet has multiple ...

AI Technical Summary

Problems solved by technology

[0004] However, most of the current data recorders use on-board solid-state hard disks for storage, and data reading and analysis consume manpower and material resources; the running status of the train cannot be grasped in time, and the fault diagnosis process is redundant and time-consuming

In many newly opened subway lines, although data recorders with 4G / WLAN connection and transmission functions are equipped, the signal transmission volume is not large, and the real-time operation status of the train cannot be grasped in time

Secondly, the current data logger has a single interface and poor versatility

[0005] Handling and analysis of train faults Wait until the train is offline and out of service, the timeliness of troubleshooting is greatly reduced
