The present invention relates to a mobile terminal and a train inspection and railway operation safety management system using the same.

Trains are a very important means of transportation and logistics because they can carry a lot of passengers and carry a lot of cargo at the same time compared to ordinary vehicles.

Therefore, as the logistics volume increases and high-speed trains appear in recent years, the use of trains is gradually increasing.

These trains are connected to a plurality of driven cars in front of the power car to run at high speed on the rail, so many casualties and physical damage can be seen in the event of an accident. Therefore, safety prevention is the most important issue in the operation of trains.

However, because the rails on which trains run are connected across the country, or between countries and continents, at distances of tens to thousands of kilometers, it is easy for the engineer to drive by keeping a watchful eye while driving the train for a long time. not.

In addition, when obstacles appear on the rails or around the rails, or when normal train operation is difficult due to bad weather or natural disasters, the managers go out to the site and check the situation. After the matters are received by the operation control center, information on the matters confirmed by the operation control center will be notified to the train operating the train, the trains to be operated, and the site management center. There is a problem that takes a lot of time to inform the facts.

That is, in the conventional case, an accident occurrence or abnormal train operation signal due to a railroad error is received by the operation control center, and the operation control center sends the location information and confirmation order of the corresponding railroad to the regional management center of the region, The management center sends the location information and confirmation command to the manager of the area in order, and finally, the inspector in the area moves to the location of the railway where the abnormality occurred and checks the status of the railway status and abnormalities. The results were reported in reverse and reported to the Operational Control Center for processing.

However, in this way, the entire operation control center transmits the information on the occurrence of abnormality and the confirmation order through the subordinate management system step by step. As soon as the information is not delivered to the working workers, and the information transmission time is delayed, stable operation of the railway is not easy and secondary safety accidents are not prevented in advance.
