Description

A COMBINED ON-BOARD TRAIN SYSTEM FOR USING AN AUTOMATIC TRAIN CONTROL, AN AUTOMATIC TRAIN STOP AND AN AUTOMATIC TRAIN PROTECTION}

The present invention relates to a combined vehicle system capable of operating a train on a route having different ground signal equipment, and more particularly, to an ATC, an ATS, and a train to the same route on which the train will operate. The present invention relates to an ATC-SP combined on-vehicle device that can be easily switched between ATC, ATS, and ATP, regardless of whether different ground signal equipment such as an automatic protection device (ATP) is installed.

In general, a signal control system for the safe operation of train operation is classified into a ground signal system in which a control center is a ground signal device and a vehicle signal system in a vehicle, and ATS facilities are representative of the signal system. There are many types according to the transmission / reception method and additional function of onboard signal, but ATP or ATC facility is typical.

The ATS (Automatic Train Stop) system is a device that automatically decelerates or brakes the speed of the train in order to prevent a collision with the preceding train when driving exceeding the speed limit of the signal.

The ATP (Automatic Train Protection) system is a device that automatically controls the speed of subsequent trains according to the location of preceding trains by receiving information required for train operation through grounders (Balise, Beacon, etc.) installed on the track. It is possible to leave the signal system without dismantling or switch to the next-generation signal system by using a ground signal.

The ATC (Automatic Train Control) system is a vehicle signal system that transmits the train operating conditions on the ground to the vehicle using track circuits or information transmission devices and displays the allowable speed continuously in the car, and the speed of the train exceeds the allowable speed. In this case, it automatically stops or decelerates the train within the allowable speed. It adds automatic acceleration function, stop position, door opening, etc. to ATP function, and is used for KTX.

Since the various types of automatic train control devices described above are distributed and installed on subway lines and national railways, in order to operate a track on which a ground device of a specific train control auto control device is installed, a vehicle system of the same automatic train control device is installed. Only trains can operate. This is because the efficiency of the train operation can not be improved, the compatibility of the train for each operating line is lacking, and this causes a problem that it is difficult to efficiently train according to the traffic conditions of each operating line.

In particular, in the case where the ground devices of the automatic train control system are divided into two or more kinds of sections, in order to operate the train, it is economical to install two or more onboard trains corresponding to each automatic train control system. There is a problem that a large cost is required.

Furthermore, two or more kinds of onboard devices can be installed in a train to switch the operation, but the control state of the automatic train control system can be switched from one automatic train control system to another automatic train control system. In the city, there is a problem that can be caused by a malfunction due to immaturity of the switching operation, and an accident due to careful attention and skilled skill.

In order to solve the conventional problems as described above, an object of the present invention is to enable the train operation in the ATC-ATS-ATP mutual section so that the train can be operated regardless of the route installed by the ground device of the different signal system divided by section To provide an ATC-SP combined car-mounted device.

In addition, the present invention can automatically operate the train by selecting the signal automatically without the need for a separate switching process to prevent malfunction or accidents due to the immaturity of the driver even when operating a route installed with a different signal system An object of the present invention is to provide an ATC-SP combined onboard vehicle.
