As the ATS / ATC integrated On-board signaling system, an integrated system of automatic train stop (ATS) and automatic train control (ATC), ATS and ATC sections can be operated as a single system by establishing an optimal signal device.
On-board Signaling System consists of ATS / ATC Rack, Aspect Display Unit (ADU), ATC Antenna, ATS Antenna, ATS Antena Junction Box and Tachometer generator.
ATS, ATC Function
ATS function of Interittent Control Multi-Variable, continuous velocity inspection mode is integrated with ATC function of ground continuous speed code inspection mode.
There is the function of automatic switching and manual switching between ATS / ATC signal systems.
It provides test function for safe operation of the train through operating the ATS/ATC system in a virtual sequence of operations before the vehicle leaves the base and checking abnormality of signal and braking device in advance.
Redundancy System design
With the application of redundancy system, it is possible to operate without any change since it is switched to the standby system in case of operating system failure in operation.
10.4 “Touch TFT-LCD displays operation information such as speed limit and notifies the driver of the audible warning sound according to the situation. The driver can operate emergency operation, 15 km / h operation, pre-departure test, etc. with screen touch.
Operation Record Function
When a fault occurs, it is easy to identify the cause, and it can be used for maintenance work since various driving events occurred during train operation are saved in memory.
The information can be downloaded with LAN by using dedicated software.
The ADU has a large capacity memory that periodically records information such as transmitted signals from the ATS/ATC Rack, train speed, etc., and saved information can be checked using dedicated software.
Domestic: KORAIL EMU
It consists of a redundancy system of 1 system (main operating system) and 2 system (auxiliary operating system) to control ATC and ATS function and interfaces to each other between vehicles and components.
Man Machine Interface (MMI)
The driving information such as the current speed, the state of doors, and the speed limit of the vehicle is displayed and notifies the driver of the audible warning according to the situation depending on the information transmitted from on-board ATS/ATC Rack installed in the driver’s compartment.
• 10.4” TFT LCD, Touch Screen
• Automatic screen brightness control, Selt Test function
• S / W upgrade using USB and download log information function
It is installed at the front part of the front axle of the forward of EMU and receives speed code information from the wayside signal system via the rail.
It is a device to transmit the variation signal to ATS Rack responding to the ATS wayside coil on the control point.
ATS Junction Box
It is an intermediate connection between the ATS Antenna and ATS/ATC Rack and makes it easy to install and maintain.the wiring.
