• The equipment of the traction substation and step-down station is scattered, monitoring islands are isolated, and fault location is difficult • Traditional architectures have a single point of failure risk and cannot meet the unattended requirements. • Traditional solutions are fixed, insufficient flexibility, and difficult to expand | AC and DC power supply systems | The AC and DC power supply system is an intelligent power solution designed for rail transit traction substations, step-down substations and traction step-down hybrids, and its core lies in the deep integration of traditional discrete AC power screens and DC power screens through advanced intelligent integration technology to build a unified high-reliability power supply platform. The system not only realizes the centralized and high-quality power supply of AC and DC mixed loads in the station, but also carries out unified monitoring and intelligent management of the operating status, power quality, battery health and energy flow of the whole system through the integrated monitoring unit, and supports automatic switching of dual power supply, intelligent battery maintenance and remote "four remote" functions, so as to ensure the safety and continuity of rail transit power supply, significantly improve the operation and maintenance efficiency and energy management level, and is the key infrastructure to support the intelligent and intelligent operation of the rail transit power system. | • High frequency and high efficiency, dense power • Module redundancy, online maintenance • Panoramic view, intelligent alarm • Global parameters, remote control • Open protocol for seamless access • Plug and play for easy maintenance | • Improve power supply reliability and eliminate single points of failure • Unified monitoring simplifies operation and maintenance to meet the unattended needs of intelligent substations • Optimize life cycle cost (TCO) • Support intelligent upgrading and sustainable development |
• Energy efficiency black hole with high operating costs • Extensive management, passive and inefficient operation and maintenance • Experience solidification and lack of scene intelligence • Siloed systems and silent data value • Reliability and compatibility challenges | Smart lighting power system | The smart lighting power system solution is a set of "source-network-load-intelligence" integrated digital lighting management system that deeply integrates power electronics, Internet of Things and data analysis technology. The solution takes intelligent and highly reliable lighting power supply as the core of perception and control, and realizes the deep integration of power supply management, status monitoring and policy control of global lighting equipment by building a multi-modal converged communication network and a cloud-edge collaborative computing platform. The system not only completes the hardware upgrade from "traditional power supply" to "adjustable, controllable and measurable digital power supply", but also realizes the paradigm shift of lighting business from "empirical operation and maintenance" to "intelligent operation" through data-driven, providing the overall value delivery of a safe, energy-saving, efficient and sustainable light environment for various scenarios. | • Manchester coded dimming, 0-100% stepless adjustment • The overall energy efficiency of the system ≥ 95%, and the comprehensive energy saving is 40%-70% • Support multiple scenario modes such as normal operation, shutdown, and fire protection • Illuminance sensor linkage for on-demand lighting • Seamless integration with BAS/ISCS for remote centralized monitoring | • Reduce electricity bills and O&M costs to achieve a quick return on investment • Improve the level of management refinement and operation and maintenance automation, free up manpower, and improve efficiency. • Improve the light environment experience of passengers and contribute to the construction of green subways • Build perceptible, manageable, and optimized urban digital infrastructure nodes |
• Traditional evacuation indication systems cannot dynamically adjust direction • Battery maintenance is difficult, may fail in an emergency, and does not meet the requirements of the new national standard of GB 51309 | Intelligent evacuation power system | The fire emergency lighting and evacuation indication system adopts advanced bus technology and power electronics technology, integrates all emergency lamps and supporting equipment in the building, and the system host monitors the working status of the terminal lamps and equipment of the system in real time 24 hours a day. It enables the fire scene personnel to quickly evacuate through the real safety route, so as to guide the personnel to avoid smoke and fire escape safely, accurately and quickly, and avoid casualties to the greatest extent, which effectively solves the defects of the traditional evacuation system such as fixed direction, unsatisfactory indication effect, high maintenance cost, and poor safety performance. | • Intelligent dynamic guidance for safe and precise escape • High reliability two-bus architecture, flexible and efficient deployment • Distributed intelligence with high-speed response • Non-polar wiring design, convenient and reliable construction • Guided by light and sound to improve escape efficiency | • Millisecond switching, safe voltage output, guarding the life channel • National standard certification, automatic inspection, and worry-free fire acceptance • Intelligent management extends battery life and reduces O&M costs by 50% • Remote monitoring, black box traceability for predictive maintenance |

When the mains power is lost, the UPS outputs the battery energy inverter to the load to achieve uninterrupted output. All power converters (such as triac rectifiers, IGBT inverters, etc.) and system components (such as bypass and static switches of inverters) used in this series of UPS are controlled by advanced DSP (Digital Signal Processor). The high speed and precise control performance of DSP greatly improve the control accuracy of the UPS, further enhance the reliability, and achieve stable, clean and uninterrupted power output. At the same time, it also provides diversified communication solutions and friendly human-machine interfaces, which is convenient for users to design and monitor the machine. | • Online dual-conversion DSP technology • Independent air duct heat dissipation design to ensure uniform heat dissipation of the whole machine • Automatic bypass and external manual bypass design to ensure uninterrupted power supply for repairs • Redundant design of power strips to ensure a safer system • Pure sine wave output, high voltage accuracy, low total harmonic distortion • Rich communication interfaces, equipped with RS485, RS232, RJ45 and other interfaces | • Ensure the continuous operation of core systems such as signals and communications, and eliminate operation interruptions caused by power supply problems • Easy operation and maintenance, reducing fault repair time • Efficient and energy-saving directly reduces electricity bills; intelligent battery management extends battery life and reduces replacement costs • Transform UPS from a "black box" device to a digital asset for transparent management |
