In addition, the line operator is connected to the terminal system or client computer system to the situation room system via the wireless Internet network or wired Internet network to input and modify the track work information.

In addition, if there is no response operation of the engineer (eg, train speed deceleration, train stop, etc.) without the safety confirmation signal received in the train system so that the train reaches the working position, the train operation control device controlling the train operation is controlled. It is to prevent accidents due to unresponsiveness of the engineer by inputting signals to control train operation.

As is well known, trains are mass transportation means that high safety is the first priority, and many devices are continuously developed to ensure the safety of trains and passengers, improve the operation efficiency and service quality, and improve driving convenience. come.

AUTOMATIC TRAIN STOP SYSTEM (ATS), AUTOMATIC TRAIN PROTECTOR (ATP), AUTOMATIC TRAIN CONTROL SYSTEM (ATC), AUTOMATIC TRAIN OPERATING SYSTEM (ATO) Train control systems (TCS) such as train control and monitoring system (TCMS) are the representative devices to secure the safety of trains, improve operating efficiency and improve driving convenience.

These train operation control devices are devices that secure the safety of the train by detecting the occupation of the tracks of the preceding train to control the train operation, and further enable unmanned automatic operation by exchanging information on the train operation.

As technology advances further, safety becomes more important as the train speeds up, the number of trips increases, and passenger traffic increases, and the concept of safety has advanced from the safety of the train itself to the safety of the surroundings of the train.

Train access warning devices that notify rail workers of train access and evacuate ahead of time are a very useful device for securing worker safety.

In this case, there is a problem that it can not be practically used. Second, because it detects and informs whether a train enters through a wireless communication device, the problem that the signal transmission reliability is degraded and cannot be used in a radio shade area or a disturbance area. Third, there is a problem that the accident can not be prevented when the worker does not hear the alarm to enter the train, or evacuated due to the inevitable situation, and fourth, the train driver does not know the location of the work Of course, you can check whether the operator has evacuated by hearing the train alarm. There was no problem.

As the industry developed, the technology of location detection using GPS and mobile communication using mobile communication network further developed, and this technology was introduced to the train approach warning device to further develop the train approach warning technology.
