Thanks to CTOnews.com netizen West Window old clues delivery! CTOnews.com June 29 news, China's first 80 km/h A "China standard" subway train officially released in Guangzhou today, will be put into operation in Guangzhou subway.

According to introduction, the train fully adopts Chinese standards, applies autonomous key components, completes test verification, marking that China's urban rail transit equipment level has entered a brand-new stage.

The train was jointly developed by CRRC Changke Co., Ltd. and Guangzhou Metro Group. It has achieved autonomy of key components, generalization of parts, modularization of parts, system integration, functional configuration and standardization of the whole vehicle. Major breakthroughs have been made in key core technology research. Key systems such as car body and bogie have fully adopted Chinese standards. 28 key components such as bearings, couplings, chips and high and low voltage electrical components have achieved autonomy, breaking through foreign technology monopoly. It greatly reduces the cost of train maintenance and operation, promotes industrial scale and standardization, and has the characteristics of advanced wisdom, green energy saving, safety and comfort. It is the latest independent innovation achievement in the subway field in China.

China standard subway train is a brand-new product platform with technology leading, which is dominated by Chinese standards, adopts the design concept of standardization, modularization and serialization, inherits the existing subway train operation experience, and independently develops in combination with the domestic subway user demand. Metro trains can be divided into A, B, C and other models according to the width of the car body, among which Type A trains have the largest width and the largest passenger capacity, and 80 kilometers per hour is also the speed grade adopted by most urban center subway lines.

The successful development of 80km/h Type A Chinese standard subway train marks the important achievements of the series of Chinese standard subway train projects, further solves the bottleneck problems restricting the development of urban rail transit in China, such as dependence on imports of key parts and lack of unified products and technical platforms, and helps China's urban rail transit achieve high-quality development.

As an additional vehicle purchased by Guangzhou Metro Line 2, the brand-new metro will take the lead in verifying the feasibility of the national major technical equipment tackling project-80km/h A-type Chinese standard metro train platform, laying a foundation for the interconnection and exchange of spare parts of subsequent metro vehicles, thus improving vehicle utilization rate, reducing spare parts hoarding rate and reducing operation cost.

This series of standard trains also has a great breakthrough in intelligence. It is equipped with intelligent operation and maintenance system, which can realize real-time detection of online status of key train systems. Data can be transmitted to Suiteng OS platform of Guangzhou Metro. Official personnel can track the real-time status of trains, collect data analysis and excavate hidden dangers through Suiteng OS platform, so as to realize intelligent operation and maintenance of train life cycle.

At the same time, it is also equipped with bow net, track, tunnel and other comprehensive detection systems, combined with the actual operation conditions to monitor other professional equipment, as if equipped with "subway doctor."

It is said that through the intelligent operation and maintenance system of vehicles based on Suiteng OS, the data interaction between vehicles themselves and other specialties such as signals, power supply and tracks has been realized, a unified platform for data fusion and data multiplexing has been built, and a solid foundation has been laid for building Guangzhou Metro intelligent ecosystem.

This series of trains adopts permanent magnet traction system and comprehensive energy-saving control technology. Compared with traditional asynchronous traction system, the whole vehicle saves more than 15% energy; lightweight high-frequency auxiliary reverse system is adopted, which reduces the weight of each train by more than 600 kg, further reducing the operation energy consumption; train air conditioner has air purification and virus killing functions, improving the air quality of passenger compartment and creating green train.

CTOnews.com believes that safety and comfort are the most important concerns for passengers. According to the official, its standard train meets or surpasses the requirements of standardized subway in reliability, availability, maintainability and safety technical indicators (RAMS), optimizes the vibration and noise indicators of key components in combination with line characteristics, and cooperates with active noise reduction technology to bring quiet and comfortable riding space for passengers. With the goal of optimizing passenger experience, temperature and humidity sensors and CO2 concentration sensors are added to comprehensively adjust the indoor environment of the passenger compartment, and the warm and cold compartments are divided according to passenger demand, which can provide comfortable riding experience for passengers.
