Business On-board Signalling System
ATC/ATO Device
ATC/ATO On-board Signaling System is the device that displays continuously the allowable speed of the vehicle by receiving operating conditions on the wayside and performs the function of automatically stop or decelerate trains if the train exceeds the permissible speed and automatic operation function to stop the vehicle in the right position by slowing down the speed according to ATO marker detection at the time of station entry. CSIN Tech manufactured and supplied On-board Signaling System consists of ATC/ATO Rack, Aspect Display Unit (ADU), Tachometer, ATC Antenna, TRA Antenna, TRA Antena Junction Box, TWC Antena and TWC Antena Junction Box.
Major Products
-
Aspect Display Unit(ADU)
The driving information such as current speed 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 ATC/ATO Rack installed in the driver’s compartment.- 10.4” TFT LCD, Touch Screen
- • Automatic screen brightness control, Self Test function
- S/W upgrade using USB and download log information function
-
ATC/ATO Rack
It is On-board signaling system that carries out the automatic operation through the function of ATC, automatically stops or decelerates a train if it exceeds the permissible speed and stops in the exact spot in the train station by decelerating speed according to ATO marker detection.It consists of Control Power module (redundancy system), Control Rack (redundancy system composition), Receiver Rack (single system composition), Receiver Power Module, and Test Module.
-
ATC Antenna
It receives information from the speed code via the rail(Railway circuit). -
TRA Antenna
It can detect the PSM of the route and receives location information for the train to stop in place. -
TWC Antenna
It is an information transmission medium and is transmitted/received in a digital modulation method with the wayside loop. -
Tachometer
It generates pulses according to the rotation of the wheels, and the On-board Signaling System calculates the speed of the train using the pulse signals of the tachometer. -
TRA Junction Box
It is an intermediate connection between the TRA Antenna and ATC/ATO Rack and makes it easy to install and maintain the wiring. -
TWC Junction Box
It is an intermediate connection between the TWC Antenna and ATC/ATO Rack and makes it easy to install and maintain the wiring.
Major Function
-
01
TWC
Function
It performs the function of information sending and receiving with wayside devices installed in the station when a train enters the station and stops.
-
02
Train Speed Computing
It displays the speed by computing the value of wheel diameter and the speed pulse signal from the tachometer installed on the axle of the train.
-
03
Stop to the
Right Spot
It performs the function to stop the vehicle in the right spot by slowing down the speed according to wayside installed ATO marker detection at the time of station entry.
-
04
Speed Limitation Information Recognition
It recognizes the speed limit information by receiving the signals in the closed loop installed in the railway with a pair of ATC antennas installed under the train (TC car).
-
05
Pre departure
Test
It is the test to check safe operation of the train through operating the ATC/ATO device in a virtual sequence of operations before the vehicle leaves the base and checking abnormality of signal and braking device in advance.
-
06
User
Interface
Aspect Display Unit displays the operation information such as the speed limit on a 10.4" Touch TFT-LCD and notifies the driver of the audible warning according to the situation. Emergency operation, 15km/h operation, and a pre-departure test can be operated.
