Train Operation Safety Management System {A SAFETY SUPERVISION SYSTEM FOR TRAIN SERVICE}

The present invention relates to a comprehensive safety management control system for train operation, and more specifically, each train is provided with a driving recorder (Black Box) for detecting and recording the overall operating state and the current position of the train, By using the recording device, it is possible to grasp the environment of trains (cars) or railroads, so that it can be used as an analysis data for safe operation of the trains later. Related to the railroad safety management system to ensure the safety of the train operation by ensuring the real-time monitoring of the construction section and railroad crossing section of the railroad tracks and the control of the central control system to determine the risk situation. will be.

In recent years, the domestic train accidents are very large, and in this case, the loss will be enormous, including the direct human material damage as well as the indirect damage caused by delayed logistics transportation including passengers.

This means that the railway transportation sector, which makes up a large portion of logistics transportation, is relatively behind its importance compared to other existing transportation infrastructures.

In particular, train accidents that occur frequently in railway construction sections or railroad crossings are not simply a matter of human accidents, but even after the damages are dealt with and the accidents are terminated, the sequelae that occurs does not become a simple financial form of compensation. The reality is that after the accident, the victim or the perpetrator of the accident will cause various direct and indirect problems.

Therefore, in order to solve such a problem, a number of techniques related to a train safety driving system have been disclosed.

However, in the conventional train operation system, a system for controlling a branch point of a track, a station yard, or a crossing is mostly limited to the local train operation control.

The present invention has been made under the above-mentioned background, and an object of the present invention is to provide a driving recorder (Black Box) for detecting and recording the overall driving state and current position of the train, and using the driving recorder. By understanding the environment of trains (cars) or railroads, it can be used as an analysis data for safe operation of the train in the future, and when abnormal situations arrive during the operation of trains, these situations are transmitted to the central control system in real time to prevent accidents. It is to provide a train operation safety management system that monitors the situation of railroad crossings and railroad crossings in real time and is under the control of the central control system that determines the risk situation.
