High-speed railroad is the compound of high-technology, and is effectively controlled by on board computer system. On board computer system refers to the computer equipment and subsidiary devices, the network transmission system linking computers, the serial link connecting computers with subsidiary devices, the input-output control line for train condition check and operation order and etc.
Checking train conditions and train order control function such as operation order, and train control
Supporting engineer’s driving and providing defect-repairing information
Providing defect-repairing information to repair maintenance workers
Supporting train crew preparation and providing data wireless transmission interface (remote control function, service maintaining function)
Supervising passenger convenience facilities and providing defect alert in text for train crews
During the cold winter when there is no operation of transport, railroad is often covered with snow and ice. Therefore, when the first train runs next morning, it intervenes contact between overhead contact wire and pantograph, and causes decline in current collecting and negatively influences the vehicle or electric devices on ground.
In order to prevent such situations, thawing system using theory of electric heater to radiate heat with electric resistance will melt the ice and snow on overhead contact wire and send electricity safely to the train.
Trucks are the running gear of railroad vehicles. High-speed railroad vehicle uses free-motion articular trucks. Articular trucks are made as human body joints move freely. They are light and noiseless and provide a comfortable ride. Also, in case the train is derailed, there is less risks of destruction due to the wheel structure of a single iron-body type
Automatic Train Control(ATC), Interlocking Device(IXL), Centralized Traffic Control(CTC), Trunked Radio System(TRS), Supervisory Control And Data Acquisition(SCADA), Measure Information System(MH) and etc
