Control Apparatus for Automatic Switch to Main Information Process Module in Train Control System}

The present invention relates to signaling equipment for railway, subway, and affiliated railroads, and is a sub-system of an interlocking device (IXL: Interlocking) interlocked by control of a train control system. All inputs and outputs are automatically transferred to the main information processing module (hereinafter, abbreviated as "circle") even if a fault occurs due to an external surge or the switch is removed. The present invention relates to an automatic switching device to a main machine using a relay in a train control system for maintaining a communication interface with a device.

In general, as illustrated in FIG. 1, a train control system (TCS) is generally classified into an automatic train control (ATC) 2 and a centralized traffic control (CTC) 3. Each device is connected to each other through a communication network.

Here, the interlock device 4, which is a sub-system of the train control system 1, is installed in the station's machine room, the interlocking machine room (IEC), and the outdoor equipment box (OT), which is the central level (CL) and the site. It is divided into information processing module of level (LL) and trackside level (TL).

The track side information processing module is a facility for safely configuring the course of a train and presenting driving conditions to a train crew. It is a system for interworking a signal and a track changer. It is to achieve the purpose.

The track information processing module is a device that performs interworking by an electrical or mechanical method such as a signal switch and a track changer to support smooth train operation in a station yard.

However, the line side information processing module included in the interlocking device 4 described above has a control object having DC or AC input / output characteristics by one module, and has no failure prevention function.

That is, the general line side information processing module does not take any means to check whether the cause of the error is the failure of the control device or the transmission line when a signal error occurs, so that the time for checking the cause of the error is long. Not only that, but also the problem that could not prevent accidents due to errors inevitably.

Accordingly, in the event of a failure of the trackside information processing module, conventionally, the entire train signal system may be affected, which may result in enormous economic and social losses, furthermore, loss of life, and thus, a very high cost. The ripple effect was very serious.

In order to improve such a problem, conventionally, after multiplexing the track side information processing module and monitoring the abnormality of the multiplexed track side information processing module in real time, if a failure occurs in one information processing module, Korean Patent Registration No. 10-0673535 discloses a switching system and a method for multiplexing an information processing module of a train track to automatically switch to another information processing module for multiplexing.
