Description

Device Recorder for Railway Vehicles {Device For Recording Events of Train}

The present invention relates to an event recording apparatus mounted on a railroad car, and more particularly, to a sensor and a camera and a vehicle in a railroad car in a black box type event recording device storing various event related data that may occur during the operation of a railroad car. By combining the data input from the control device as a plurality of different data units to have a plurality of different memory modules for storing each of the different data units, it is possible to determine the exact cause from a variety of angles when an event occurs In addition, it relates to a new railway vehicle event recorder that improves the reliability and safety of stored data.

Conventional trains are equipped with a recorder, that is, an event recorder for storing the train speed and operation information during operation to check the status of the train or to analyze the cause when a train accident occurs. In the event recorder, since the storage means is formed in a single structure, there is a problem in that, in the event of an error in data storage, analysis of data for analyzing the cause of an accident is impossible.

In order to solve this problem, a conventional train driving information recording apparatus has been proposed in which a backup memory means is added. For example, the same data is simultaneously stored in a registered publication of Korean Patent No. 10-10414475 (registered on June 8, 2011). An apparatus having a memory module configured as dually as possible is described. Accordingly, even when an error occurs in any one memory module, train operation information may be continuously recorded in another memory module used for backup.

However, in such a driving information recording apparatus having a backup memory module, only vehicle speed information and driving information are stored, and information such as image information for intuitively identifying a situation cannot be stored. There was still a problem that it could be insufficient to use as sufficient data to determine the cause of the problem. In addition, since the same data is stored in each of the dual memory modules, there is a limit to providing data for analyzing the cause of the event from various angles. Furthermore, in the conventional apparatus, data was stored only in a vehicle, and after the event occurred, the recording apparatus could be read only after disconnecting the recording apparatus from the train and connecting the cable to an external system such as a control room. This makes it necessary to strongly protect the outside of the recording device against shocks, and it is difficult to cope with intrusion through communication networks such as hacking.

Therefore, in the event recording apparatus for railway vehicles, it is possible to determine the cause of the incident from various angles by storing various types of data, and to diversify the storage module to prepare for errors in record storage, and also in real time If the system is configured to transmit data wirelessly, it would be advantageous not only to be available as sufficient data for determining the cause of the event but also to secure the safety of the data.

The present invention has been made in order to overcome and solve the problems of the prior art described above and to provide various additional advantages. The present invention provides a black box-type event recording apparatus for storing various event-related data that may occur during the operation of a railroad vehicle, and not only driving information input from a control device or sensor mounted on the vehicle, but also image information from a camera mounted on the vehicle. It is an object of the present invention to provide a new railway vehicle event recorder that allows for the recording of abundant data that allows input to be interpreted at various angles.
