China Net: Commissioner Zhao，Hello！Welcome to be a guest on China.com’s “China Interview” program。
Zhao Hongwei: Dear netizens of China.com，Hello everyone！I am Zhao Hongwei, member of the 14th National Committee of the Chinese People’s Political Consultative Conference。
Member of the National Committee of the Chinese People's Political Consultative Conference、Zhao Hongwei, 188bet app Chief Researcher of China Academy of Railway Sciences Group Co., Ltd., was interviewed by China.com's "China Interview"。 China.com Yang Jia Photography
China Net: my country is currently the country with the fastest high-speed rail operations in the world。We are paying attention to April 2022，CR450 sets a world record for open line intersection speed of high-speed rail EMU trains，This marks the full launch of the “CR450 Science and Technology Innovation Project” included in the country’s “14th Five-Year Plan”。We would like to ask you to introduce it，Current research and development status of 188bet sports betting CR450 EMU？What are the difficulties and highlights of this technological breakthrough？
Zhao Hongwei: "CR450 Science and Technology Innovation Project" and the development of CR450 EMU have been included in the country's "14th Five-Year Plan"，The development of EMU is currently in progress。In January 2022，Promulgated the "Overall Technical Conditions for CR450 EMU"，Specifies the line conditions for EMU operation、Operational requirements and other technical requirements，More importantly, it also has some intergenerational characteristics requirements，To further consolidate my country’s leading position in high-speed rail，R&D faster、More secure、More environmentally friendly、More energy efficient、More intelligent、EMU with better system provides fundamental basis and compliance。
There are still many difficulties in the development of CR450 EMUs。For example, it is required to further reduce the energy consumption of EMUs，This requires further reduction in air resistance on the one hand，At the same time, 188bet sports betting the efficiency of the traction system must be improved。
The second difficulty is the braking distance，Need to adopt some new technologies、New materials lower it down。Therefore we need to overcome many difficulties。
Furthermore, the noise level needs to be further reduced。From 350 kilometers per hour to 400 kilometers per hour，The noise increase is also 2 to 3 decibels，To achieve a noise level of 68 decibels when operating at a speed of 400 kilometers per hour，Requires us to reduce the noise caused by the increase in speed。This also requires the further application of some new technologies、New sound-absorbing and sound-insulating materials reduce the corresponding noise，This requires the adoption of many new technologies in EMU structure and material application。This is the difficulty in the development of this EMU，It will also become the highlight of the successful development of this EMU。
China.com: This year is the first year to fully implement the spirit of the 20th National Congress of the Communist Party 188bet Online Sports Betting and Casino of China。Next step，In what aspects will China’s high-speed railway develop to contribute to my country’s realization of a higher level of modern railway power？
Zhao Hongwei: Now we are fully developing the “CR450 Technology Innovation Project”，At the same time, develop the CR450 EMU。CR450 EMU will have higher operating speed，More secure、More energy-saving and environmentally friendly、More intelligent，At the same time, the system is better。
Speaking of higher operating speeds，We will further improve the technical standard system for a speed of 400 kilometers per hour，Achieve self-reliance and self-reliance in science and technology，Finally achieved commercial operation with a speed of 400 kilometers per hour。
In terms of greater security，By adopting some more stringent safety standards，Safety from wheel rail、Powder and Net Safety、Carry out the design of EMUs in terms of structural safety and other aspects。simultaneously，Some monitoring methods will also be used，To further ensure the driving safety of EMUs。
188bet best bookmaker In terms of energy saving，EMU will further use energy-saving and environmentally friendly materials，simultaneously，Adopt some energy-saving and environmentally friendly facilities such as wastewater recycling and reuse devices。EMU will further reduce energy consumption，Improve efficiency，Ultimately, the energy saving and environmental protection level of the EMU will be further improved。
In terms of intelligence，EMU will adopt TSN time-sensitive network，Building a new generation of in-vehicle network，At the same time, using 5G mobile communication technology to establish vehicle-to-ground communication connections，Building a foundation for intelligent operation and maintenance，Evaluate health status and predict faults。In the end, the EMU is not only the best in one aspect，But to achieve system optimization。
In short，CR450 EMU will have higher operating speed，will be more comfortable、More secure。
China Railway has always been a leader in the field of high-speed railway，Passed the development of CR450 EMU，will further consolidate and expand 188bet our country’s leading advantages。China Railway will also provide support and services for Chinese-style modernization。
China.com: Thank you for being a guest on our program again.
Zhao Hongwei: Thank you.
