In the urban rail transit network, the platform door system, as the "first line of defense" to ensure passenger safety and maintain operational order, is directly related to the travel safety and commuting efficiency of tens of thousands of passengers. Behind all this, it is inseparable from a reliable, intelligent and efficient core support - the platform door power supply system.

Huiyeda has been deeply involved in the field of rail transit power supply for 30 years, and its self-developed platform door power supply system, with the core advantages of "dual redundancy architecture + super instantaneous load and power supply capacity + intelligent monitoring + full-scene adaptation", has become the trusted choice of more than 400 rail transit lines and more than 7,000 stations at home and abroad.

The platform door power supply system adheres to the concept of modular and hierarchical design, consisting of four core parts: drive power supply, control power supply, power distribution unit and monitoring unit. The design can be flexibly configured according to the specific needs of different platforms, providing the most suitable solution for both new lines and old line renovation projects.

Our technical advantages: not only power supply, but also intelligent empowerment, integrating high intelligence, high reliability and stability, and high efficiency and energy saving

Fully redundant and high-reliability architecture design to achieve zero interruption of power supply

The system adopts N+1 redundancy design of all modules of drive power supply and control power supply, and all core modules support online hot swapping. Any module failure can be switched instantly without inductive, and non-stop maintenance can be realized, which builds the highest level of reliability cornerstone for the safe operation of the subway.

Super instantaneous load and power supply capacity

The drive power supply has an instantaneous overload capacity of 2.5 times the rated power, which can easily meet the peak power requirements of the platform door motor at the moment of starting, anti-pinch and other moments, ensuring that the door body can move quickly, smoothly and accurately under any circumstances;

Intelligent battery life cycle management

The system independently manages power supply and charging, and monitors battery voltage, temperature, and internal resistance in real time. Health assessment and preventive maintenance are carried out through intelligent algorithms to maximize the life of the battery pack and ensure that emergency energy is always in the optimal state.

Panoramic intelligent monitoring and convenient interaction

It is equipped with a 7-inch color touch screen intelligent monitoring unit and integrates full-state visual management. It supports multiple communication protocols and can seamlessly connect with the station's ISCS system and platform door controller (PSC) to achieve remote monitoring, data management, and fault warning. intelligent monitoring and convenient interaction;

Innovative separate dual power supply system architecture

Innovatively adopts independent power supply scheme for drive power supply and control power supply. The drive power supply provides strong power for the DCU and motor, and the control power supply (including UPS) provides highly stable logic power for PSA, PSC, etc., with a clear division of labor, no interference with each other, and doubled the reliability of the system.

Full EMC and high compliance

The whole system has passed a complete EMC test and strictly complies with the highest international and domestic standards such as EN, GB, DL/T, IEC, etc., ensuring stable operation in complex electromagnetic environments without interfering with other equipment, which is widely recognized by the market and the basic guarantee for safe network access.

At present, the system has been successfully applied to key lines such as Beijing Metro Line 14, Shanghai Metro Line 2, Guangzhou Metro Line 3, as well as the rail network of new first-tier cities such as Xi'an, Chengdu, and Kunming, touching more than 400 lines and more than 7,000 stations, with an operation stability rate of 99.8%, which has been highly recognized by rail transit groups in various places.

Our platform door power supply system is not just a simple power supply equipment, but a comprehensive solution that integrates high reliability, high intelligence, high efficiency and energy saving. Its core value is reflected in three levels: First, at the level of safety assurance, we ensure that the platform door system can operate stably in any extreme situation by using industrial-grade components, comprehensive redundancy design, strong impact resistance and perfect protection mechanisms, and provide the most solid protection for the life safety of passengers. Secondly, at the level of operational efficiency, we liberate operation and maintenance personnel from tedious and repetitive work through intelligent remote monitoring, predictive maintenance and refined energy management, and realize the leap from "passive maintenance" to "intelligent operation and maintenance", significantly reducing operating costs and improving the overall operational efficiency of rail transit. Finally, at the level of green development, we have maximized energy utilization efficiency by adopting advanced power electronics technology and energy-saving control strategies, actively responded to the national "dual carbon" strategy, and contributed to the construction of a green, low-carbon and sustainable urban transportation system.

Cities are developing, subways are extending, and the needs for safety and stability remain unchanged. As a leading enterprise in the field of rail transit power supply, Huiyeda has established a full life cycle service system from product design, manufacturing to installation and commissioning, and after-sales service, promising to respond within 24 hours, be on site within 48 hours, and solve problems within 72 hours, providing customers with worry-free guarantees, jointly building a safety defense line for urban rail transit, helping the construction of smart subway to a new height, and injecting reliable power into the rail transit operation of every city!
