I am responsible for the company’s products and marketing, and developed and promoted the following system:(A) Railway Signalling Dynamic Logic Electronic Drawing SystemRailway Signalling Dynamic Logic Electronic Drawing System is a set of system which realizes signal safety supervision and data intelligent diagnosis by analyzing the data of signal equipment, and judges whether the operation of signal system has safety risk and whether the signal equipment may fail. The system can be used as a subsystem of the railway signal centralized monitoring system, and can also be used independently. This functional requirement has been written into Technical Conditions of Railway Signal Centralized Monitoring System and promoted as a standard function nationwide.(B)Railway C3 Wireless Timeout Fault Localization Comprehensive Analysis SystemRailway C3 Wireless Timeout Fault Localization Comprehensive Analysis System is a comprehensive analysis system for judging the wireless operation status of 350 km/h China Railway High-speed. At present, China Railway High-speed with a speed of 350km/h uses the GSM-R wireless system to realize the communication between the trackside and the cab, and transmits the trackside-cab control information in two directions. If there is a wireless timeout between the cab and the trackside, it will cause the train to slow down from 350km/h to 250km/h, which will seriously affect the efficiency of train running. Therefore, China State Railway Group Co., Ltd. began to issue a document to solve this problem in 2022. I have worked with HollySys to start up a research project in Chengdu Bureau to solve develop this system. Once the system runs successfully, all China's high-speed rail trains will be equipped with this system, bringing huge social and economic benefits.

Centralized Signal Monitoring System 2020 (CSM 2020) is an important railway signal equipment to monitor the status of railway signal equipment, find hidden dangers of railway signal equipment, analyze and diagnose railway signal equipment faults, realize information security supervision of railway signal subsystem interface, assist and guide on-site maintenance and fault handling, and improve the application quality and maintenance level of signal system equipment. It is an essential tool system for the operation and maintenance of railway signal equipment. This system conforms to Q/CR442—2020 Technical Specification of Railway Centralized Signaling Monitoring System. As standard equipment that must be configured for each station of the railway, Centralized Signal Monitoring System 2020 (CSM 2020) has been popularized and applied in the national railways and subways, resulting in important social and economic benefits.I have led my team to develop Centralized Signal Monitoring System 2020 (CSM 2020) for Sichuan WangDa Technologies Co., Ltd. and this system has acquired CRCC (China Railway Production Certification Center) accreditation in Apr. 2022, and has been applied in Chengdu Bureau and metro lines. As provided in Expert Employment Agreement, Sichuan WangDa Technologies Co., Ltd. will continue to procure my dynamic logic electronic drawings system in its subsequent monitoring system project.

Beijing SWJTU Richsun Science and Technology Co., Ltd. is a company that I participated in the start-up. As the deputy general manager in charge of product development, I was responsible for the company’s overall product development management and technology development. The products that I planned and developed include: (A)Section Supervisory Control System (QJK) Section Supervisory Control System (QJK-KS) is one of the core control equipment of Chinese ordinary speed railway (160km/h line) and can realize the functions of section occupancy logic check, section direction control, inter-station safety information transmission, etc. This system was planned and developed by me and use to make up for the technical loopholes in The 2011 Yongwen Railway Line July 23rd Train Rear-end Accident. The system has become the standard equipment of China's ordinary speed railway. Beijing SWJTU Richsun Science and Technology Co., Ltd. occupies more than 95% of China’s QJK equipment market and has been successfully applied in more than 2,000 stations in China.(B)Signal Integrated Monitoring and Supervising System (IMS)Signal Integrated Monitoring and Supervising System is a core monitoring equipment of China Railway High-speed (CRH) and can realize the functions of safety supervision and fault alarm analysis of the whole signal system, which is of great significance to improve the safety state supervision and fault intelligent diagnosis of signal device.

I was responsible for the overall affairs of the products of the Integrated Supervisory Control Systems product line and the management of R&D center personnel, focusing on the core technology development and product promotion of the disaster prevention monitoring system. Main products include: (A) Railway Disaster Prevention And Supervisory Control SystemThe Railway Disaster Prevention And Supervisory Control System is a set of intelligent monitoring system for monitoring, alarming and early warning analysis of disasters that threaten the safety of railway operation, such as strong wind, rainstorm, blizzard, earthquake, debris flow, mountain sliding wave and high bridge falling objects, and can exercise train control in time, which escorts the transportation safety of China Railway High-speed (CRH) facing frequent disasters. The disaster prevention and safety system has been widely used in China as a necessary system for passenger railroads and above.(B) Railway Integrated Video Surveillance SystemThe Railway Integrated Video Surveillance System is a large-scale video monitoring system based on IP network. It can realize real-time video monitoring and intelligent analysis of various key areas along the railway, factories and mines. It provides comprehensive video services for various business departments and provides strong visual protection for railway transportation safety. Video surveillance products developed by Jiaxun Feihong play an important role in security system of national key programs, such as Datong-Qinhuangdao Railway and Wuhan-Guangzhou Passenger Dedicated Line.

As the manager of station signalling products department and technical leader, I led his team to complete research and development of a great number of core signalling products, which mainly include: (A) Train Control Center (TCC)Train Control Center (TCC) is one of the core control systems of the Chinese Train Control System (CTCS). It is responsible for calculation and control of various safety logics when the train runs on the section line between the two stations. I was the team leader and technical leader of TCC system in HollySys, participated in formulation of TCC norms for Chinese railways, and led my team to develop related equipment. At present, over 1,000 sets of HollySys TCC equipment have been applied in Chinese railway stations.(B) Computer Based Interlocking System (CBI)I developed an updated Computer Based Interlocking System meeting the requirements of China Railway High-speed (CRH), Passenger Dedicated Linesm and railway lines for enterprises. The new version of computer based interlocking system (CBI) realizes the integration with TCC, CSM, ATP and other systems through network communication, which together constitute the complete structure of China Train Control System ( CTCS ).(C) Line-side Electronic Unit (LEU)/Euro BaliseLine-side Electronic Unit (LEU)/Euro Balises is one of the core control systems of the CTCS /ETCS. It is responsible for sending trackside signal control commands to high-speed trains in the form of short-range wireless security messages to ensure the complete and safe transmission of trackside-train information, and realize the location of the train.(D) Automatic Train Protection (ATP)Automatic Train Protection (ATP) is one of the core control systems of the Chinese Train Control System (CTCS). It is installed on the Electrical Multiple Units and responsible for train over-speed protection.
