Application Case | JHCETCH On-board Controller Supports European Train Control System
In today’s rapidly advancing technological era, the development of smart cities has become a central theme for major urban areas. As a crucial component of smart cities, the safe and efficient operation of rail transit systems directly impacts the quality of travel and convenience of urban life. Against this backdrop, the extensive application of rail transit onboard controllers has introduced intelligent and efficient solutions to urban rail transit systems.
Customer application requirements
For subways to operate safely and reliably, they rely on the Automatic Train Control (ATC) system, which is based on wireless communication. The ATC system uses technical measures to control train direction, spacing, and speed, ensuring safe operation and improved efficiency.
This is achieved through uninterrupted two-way communication between on-board equipment and trackside equipment. Trains continuously transmit key information, such as identification, position, direction, and speed, to the control center, which dynamically calculates the maximum braking distance based on the train’s real-time speed and position. Among these, the professional on-board controller plays a critical role in data aggregation and analysis. It collects and processes data from the train’s acquisition modules and transmits the information to the control center, which in turn guides the train’s speed and position.
A European railway company hopes that JHCTECH can provide an advanced on-board computing platform with high vibration resistance, high robustness, wide operating temperature range, efficient computing power and support for remote management for the European Train Control System (ETCS). The following features are required:
⭐ Highly reliable processor platform
⭐ Compact and scalable design
⭐ Fanless wide-temperature design for robustness and stability
⭐ Efficient AI computing capabilities
⭐ Multiple I/O interfaces to ensure effective data collection
