Fault data transferring and analysis system for railway vehicles

The present invention relates to a failure data transmission recording apparatus for a railway vehicle electric train, and in particular, receives and analyzes various data including position coordinates in real time from respective components provided in the electric locomotive, and then analyzes the various data to the outside. The present invention relates to an electric vehicle fault data recording device for a railway vehicle that wirelessly transmits to a server and stores a fault point and driving record data.

In general, the introduction of computers in the field of railway vehicles began in the early 1980s, but initially only the monitor function using a speed recorder and a number of fault indicators was used to show and record the failure of major equipment installed in the vehicle. After that, with the development of computer and communication technology, the TIS (Train Information System) was developed, and the train status monitoring function such as the failure and operation status of the propulsion control system, the braking system, the auxiliary power supply system, and the status record and alarm in the event of heavy use It is now possible to generate a function. In addition, it has the function to record the operation status, fault condition, crew action contents for inspection support and accident cause analysis, and output from the ground computer device by using IC card.

Recently, however, a TCMS (Train Control & Monitoring System), which includes more control functions than the onboard information system (TIS), has been introduced in Korea. Computers can control the auxiliary power supply, high voltage and passenger service. In addition, through the interface with the Automatic Train Operation (ATO) and Automatic Train Control (ATC), the driving and braking force is instructed on behalf of the crew, thereby making constant stops and precise stops at stations. By being able to perform control functions, automatic and unmanned operation of trains became possible.

Classified as In this case, the TCMS is generally composed of a coordinated control computer, a vehicle control computer, and a monitor device, and a high speed field bus between the TCMS computer and low speed serial data communication with other devices. Receives each vehicle information and commands the control command. Furthermore, the future technical direction of the TCMS is to display and record the operation status and failure status of the main devices of the vehicle on the monitor for maximum performance of the vehicle system, and to communicate and optimize the interface between these devices. The trend is progressing to a comprehensive control device capable of performing control functions. This requires continuous research and development for the application of the latest computer technology and communication technology, and research that includes comprehensive functions considering safety and reliability from the perspective of passengers and operators. In particular, in terms of vehicle inspection support function and maintenance, inspection information (failure data) can be transmitted to the station (base) quickly through the wireless device through the interface between the onboard signal device and the comprehensive control device so that the maintenance can be performed quickly. It is necessary to strengthen the function. Recently, vehicle control devices (TIS, TGIS) that perform monitoring functions have been developed and applied to metropolitan and metropolitan electric vehicles.
