If the driving position to which the driving signal generated in the first input / output device rack 10 'is to be applied is the second input / output device rack 20', the third input / output device rack 30 'similarly outputs the corresponding signal. In this case, the second input / output device rack 20 ′ applies the corresponding signal to the I / O CPU 208 to drive the relay through the corresponding I / O card 204. Therefore, it is possible to drive a signal, a sorting light, a line converter, and the like connected to the relay.

The second input / output device rack 20 'when the driving of the signal, sorting light, and line converter corresponding to the signal transmitted from the first input / output device rack 10' is completed. The frequency generator 210 converts the driving completion signal into a frequency by data conversion.

Accordingly, the frequency generated by the frequency generator 210 is applied to the first input / output device rack 10 'via the railroad rail 4b, and the first input / output device rack 10' is a frequency detector ( 114), the corresponding data is detected and decoded and converted, and the driving completion data through the decoding is stored.

In the above flow chart, in order to explain the signal flow of the railway signal control system according to an embodiment of the present invention, it is described as being limited to driving signals for traffic lights, but this is merely described as such for convenience of description. It is not limited to a traffic light or a signal device, and means a process of transmitting driving signals to a selection light or a line converter instead of a traffic light.

On the other hand, the railway signal control system and method according to an embodiment of the present invention is not limited only to the above-described embodiment, various modifications are possible without departing from the technical gist of the invention.
