People's Daily watch Jilin: independently develops and builds high -speed rail business cards

Autonomous research and development to create high -speed rail business cards

Reporter Liu Yiqing

Compared with the experimental data, the details of the adjustment of the plan, Zhang Guoqin is designing drawings in the office. Zhang Guoqin, 40, is an engineer of CRRC Changchun Rail Bus Co., Ltd. (hereinafter referred to as "CRRC Great Passenger"), and is also the electrical design director of the Beijing Zhang Zhang high -speed rail intelligent EMU.

Layers of mountains are stacked, and there are many rocks. The conditions of the high -speed railway line of Jingzhang are complicated. Once the vehicle fails, it will directly affect the operation of the entire line. In this regard, the Beijing Zhang high -speed rail intelligent EMU creatively configures the power battery system with a two -way charging function. With the current power and the location of the vehicle, the driver moves forward and retreats according to the current power and the location of the vehicle. You can walk to the nearest station emergency.

However, the independent research and development of this item is a lot of challenges. It has occurred several times that may lead to the failure of the entire plan. Zhang Guoqin and his colleagues are precise computing, field testing, and repeated tests. I don't know how many nights have been boiled. Finally, the design team handed over the answer sheet. On the basis of the Fuxing, it innovated and developed more than 70 intelligent sub -functions of 19 major items. High -speed EMU Smart Edition 1.0.

In recent years, CRRC's R & D team has continued to work and climbed the peak. Advancing into the self -developed unmanned area, the deputy chief engineer Chang Zhenchen led the team to the problem from the tens of thousands of lines. The network control system of the standard EMU of China achieved independent control; In the operation area, 7 points for precision welding ...

The high -speed rail is a beautiful business card in my country. Zhang Guoqin said that in order to control the right of technical speech, CRRC has a channel for talent development channels such as chief technical experts and senior technical experts, and provides the opportunities for high -level titles for young people who are appraisal. In the design team of the Beijing Zhang high -speed rail intelligent EMU, more than 90%of them are designers under 35 years old. In order to do a good job of the "bidding belt", CRRC encourages high -skilled leaders to form an operator workstation, which has accumulated more than 1,300 technical problems and tens of thousands of trainers.
