Rail Transit
The global railway network serves as the artery of modern commerce and transportation. At the core of these complex systems—powering signaling, passenger information displays, train control, and communication networks - lie critical electronic components. These components require a fortress: a chassis capable of withstanding the relentless impacts, vibrations, and harsh environments encountered in daily operation.
Beijing Rdekono Electronic Equipment Co., Ltd. is a leading manufacturer of 19-inch subracks, providing robust solutions for Train Control and Management Systems (TCMS). We have developed a series of subrack installations for projects such as network units, security units, and brake units. These are deployed aboard the "Fuxing" Express EMUs (operating at 250 km/h, 300 km/h, and 350 km/h), Chinese standard high-speed trains (on lines including Jingxiong, Jingzhang, and Jinghu), as well as metro projects in cities like Kunming, Chongqing, Guangzhou, Beijing, and Tianjin.
Application: 160 km/h Power-Concentrated EMUs, installed in the leading car.
Configuration: Rack-mount, wall-mount, and pedestal-mount versions.
Beijing Rdekono designed and developed the 1.6A Central Processing Platform initially in a rack-mount subrack configuration, with subsequent upgrades to pedestal-mounted and wall-mounted structural versions. This platform remains in mass production and long-term operational service.
Electronic equipment located in the leading car is subjected to the most severe operational environment. Constant vibration and shock can lead to connector loosening, PCB failure, and data transmission interruptions. The platform demands exceptional mechanical ruggedness and system redundancy to ensure zero-false-alarm integrated alarming and continuous, secure data storage under these demanding conditions.
Core Functions: Integrated alarm processing, safety data storage, human-machine interface (HMI), centralized power distribution, real-time network transmission.
High Availability: Features a dual-processor redundant architecture for uninterrupted operation.
Scalability: Supports expandable subsystem monitoring to adapt to various train consists and functional requirements.
Installation Flexibility: Three mounting options (rack, wall, pedestal) to accommodate tight spaces within the car body.
Application: 250 km/h "Fuxing" Chinese Standard EMU.
The axle box is a critical component connecting the wheelset to the bogie, and its vibration data is directly related to operational safety. The acquisition host must filter out high-frequency mechanical noise, accurately capture specific frequency vibration signals indicative of bearing faults, and maintain stable operation under severe transient shocks to prevent data loss.
High-Precision Acquisition:Designed for processing high-frequency, high-dynamic-range vibration signals.
Shock and Vibration Resistance: Structurally reinforced for reliable operation in the high-vibration environment near the bogie.
Reliable Connectivity: Utilizes high-reliability connectors to prevent signal interruption caused by vibration.
Application Line: Beijing-Xiong'an High-Speed Railway.
Project Involvement: Jakarta–Bandung High-Speed Railway Project.
We developed a new generation of 450 km/h intelligent system subracks for the Beijing-Xiong'an line, including the main subrack for the safety monitoring system, the main subrack for the video surveillance system, and the onboard multi-network data integration platform subrack. We also participated in the design of several specialized subracks for the Jakarta–Bandung HSR.
Next-generation intelligent high-speed rail imposes extreme demands on data processing bandwidth and real-time performance. The system must integrate and process massive, multi-source data from video, sensors, and networks simultaneously. All subracks require efficient thermal management and superior Electromagnetic Compatibility (EMC) within confined spaces to prevent signal cross-interference.
High-Speed Processing Capacity: Supports the massive real-time data generated at speeds up to 450 km/h.
Multi-Network Integration: Integrates multiple network protocols and data buses.
Specialized Subrack Series:
Signal Conditioning Subrack (High-Voltage): Interfaces with and processes high-voltage side sensor signals.
Onboard Signal Conditioning Subrack (Low-Voltage): Handles low-voltage control and signal conditioning.
Pantograph-Catenary Data Acquisition Device Subrack: Dedicated to monitoring pantograph-catenary interaction dynamics.
Application: Fuxing Hao / Fuxing Series EMUs.
As a critical device for train-to-ground communication, the WTD must ensure continuous and integral data transmission under complex conditions involving high-speed mobility, frequent handovers, and significant electromagnetic interference (EMI). Its mechanical structure must guarantee stable connections for internal communication modules and maintain effective long-term thermal dissipation.
Continuous Communication: Provides a robust physical platform foundation for the critical train-to-ground data link.
Electromagnetic Compatibility (EMC): Optimized design ensures stable operation within the complex onboard electromagnetic environment.
Efficient Thermal Management: Structural design ensures operating temperatures remain within safe limits for communication modules during prolonged operation.
Application: Fuxing Series EMU.
The CCU acts as the "brain" of the train, and its reliability directly determines the vehicle's operational capability. It needs to integrate data from various train systems and execute logical decisions, placing the highest demands on the subrack's backplane communication capability, power integrity, and noise immunity. It must achieve fault-tolerant operation.
System Core: Serves as the central platform for whole-train control and decision-making.
High-Reliability Backplane: Ensures high-speed, error-free data exchange between various functional boards.
Clean Power Design: Provides stable and clean power supply to the central processors and critical chips.
Installation Location: Train under-frame.
Equipment mounted on the under-frame is directly exposed to dust, moisture, ice, snow, and impact from ballast and track debris. The electronic control units for the brake system require the highest levels of sealing and corrosion resistance, and must withstand severe shocks transmitted from the track, ensuring brake commands are executed accurately and without failure.
High Ingress Protection (IP) Rating: Features a high IP rating for effective protection against dust and water ingress.
Excellent Shock Resistance & Corrosion Protection: Materials and surface treatment technologies are suited for the harsh under-frame environment.
Mechanical Ruggedness: Structural design ensures functional integrity under long-term vibration exposure.

The subrack does not have a series of profiles, and after receiving an order, it is usually customized and processed according to the drawings. Products from different customers and products of different specifications from the same customer all need to be redesigned and processed, resulting in higher costs;
