Qingmai Enlightenment Company also maintains an office in the Amazon Technology Building, Licang District, Qingdao, Shandong Province, primarily engaged in railway equipment trade-related operations.

QM-I Fully electronic computer interlocking system

The QM-I fully electronic computer interlocking system complies with the "Technical Conditions for Computer Interlocking " issued by the Ministry of Railways and has obtained the software copyright certificate for the interlocking system As a key control equipment for railway signals, this system adopts the latest technology and uses fully electronic execution units (modules) to directly drive and collect signals, switches, track circuits, various connecting circuits, etc

QM-TDCS Railway Traffic Dispatch and Command System

The Railway Traffic Dispatch Command System (TDCS) adopts digital, networked, and information-based technologies Realize real-time, centralized, and transparent command of train operations at the stations under its jurisdiction, adjust transportation plans through automated means, and issue train schedules and dispatch commands through computer networks

CSM-QM Centralized signal monitoring system

This system consists of a central subsystem, a station subsystem, and a network transmission subsystem, with key equipment adopting a dual machine hot standby system

FZQ-CTC Decentralized and Autonomous CTC System

The FZQ-CTC decentralized autonomous dispatch centralized system is an important technical equipment for railway modernization, an important part of the comprehensive information construction of modern railways, and a new form of transportation organization for modern railways

Integrated monitoring and intelligent diagnosis system for turnouts

As an important basic equipment on the trackside, the turnout conversion system plays a crucial role in ensuring the safe operation of trains and improving transportation efficiency The switch conversion system has always been a key maintenance and repair equipment for the electrical department due to its complex and diverse application environment and high failure rate It ranks first in the on-site maintenance workload for many years

QM-DK Crossing safety protection system

The QM-DK crossing safety protection system is a safety protection system suitable for railway level crossings The system automatically implements crossing warning by detecting locomotives or trains, manually or automatically closes the crossing, and opens the crossing after the train passes, thereby achieving safety protection and control of the crossing

25Hz track circuit microelectronic receiver

By replacing the traditional binary two-position relay with a 25Hz track board card, the indoor equipment required for conventional 25Hz phase-sensitive track circuits can be significantly reduced, minimizing cabinet space occupation and substantially lowering costs

QM-YK Single driver remote-controlled operation system

To address the issues of manual operation and high personnel requirements for railway switchgear in factories and mines, this system enables locomotive drivers to perform remote switch control from the driving position, transforming the traditional "multi-person on-site operation " into a "single driver operation mode " This significantly reduces workforce requirements and enhances operational efficiency

QM-IDCC Intelligent Scheduling and Centralized Management System

By applying advanced computer technologies, operations research optimization theories, and management concepts, this approach achieves digitalization of railway production management, intelligent transportation command, and transparency in operational processes It enhances overall efficiency and safety in transportation operations, reduces workforce requirements and labor intensity, unlocks potential for increased efficiency, and establishes a modern model for railway transportation organization and management

ATO Plant/Mine/Railway Autonomous Driving System

The autonomous driving solution based on the ATO system employs CBTC (Communication-Based Train Control) technology to enable automatic control, real-time monitoring, and fault self-diagnosis

Interval rail breakage monitoring system

System Overview: The interval rail breakage monitoring system is developed based on the Provisional Technical Conditions for Rail breakage Monitoring Equipment (Tie Gong Dian [2020] No 156) issued by China Railway Group

Monitoring system for track breakage of switch rails

The system can monitor the online, real-time, and high safety and health status of switch rails and point rails Based on the propagation of sound waves in steel rails, when encountering defects or complete breakage of the rail, the energy of the sound waves will experience significant attenuation and reflection By detecting the characteristic changes of the sound wave signal at the receiving end, the state of the rail can be determined
