1100 sensors assist the high-speed experimental train of CSR

Introduction: From CSR Sifang Co., Ltd., we learned that higher-speed test trains were recently completed at China South Locomotive Sifang. The test speed of this test vehicle will be higher than the actual maximum operating speed of the train currently on the Beijing-Shanghai high-speed rail. It will carry out 11 major categories of tests. The train itself has more than 1,100 sensors and 545 sensors used in the test.

According to reports, this higher-speed test train project is under the deployment of the Ministry of Science and Technology and the Ministry of Railways, with the "Eleventh Five-Year Plan" national science and technology support project - common basis and system integration, the national 973 plan project - the key 500 kilometers per hour speed train Relying on the research of mechanical behavior, the company is mainly based on CSR Sifang Co., Ltd., and is based on the research platform opened by the National High-speed EMU Assembly Engineering Technology Research Center. It adopts a combination of production, learning, research and application. Many scientific researches were successfully completed in recent days.

It is understood that this test train is based on the CRH380A's innovative results, with the primary objective of safe and reliable operation at higher speeds. It focuses on system criticality, traction, and drag reduction to integrate system, headform, body and steering. The rack, traction and braking systems were fully innovated. The key technology of the train has achieved autonomy and industrialization in CSR.

At the scene, the reporter saw that the test vehicle body was gray, with black stripes and "CRH" signs in the middle. The front of the vehicle was like a sword, and the tail was a rocket. The reporter saw in the train that there were experimental equipment and instruments in one compartment and two compartments. The words aerodynamics experiment, lead-in relationship experiment, traction performance experiment, and brake performance experiment were marked on the label; the three compartments were integrated. In the system, all test data and information are collected and evaluated here; four cars and five cars are seats, similar to the first class CRH380A trains; the sixth car is a rocket rear.

According to the technicians, the test speed of this test vehicle will be higher than the actual maximum operating speed of the train currently on the Beijing-Shanghai high-speed rail, and 11 categories will be tested. The train itself has more than 1,100 sensors and the sensors used in the test are 545. One. From the birth of the train to the termination of service, researchers will study the factors that affect train safety, energy saving, and passenger comfort in high-speed operations.

It is understood that this test vehicle is composed of six vehicles, all of which are power cars. The level of intelligence in train safety monitoring, fault diagnosis, etc. has reached a higher level; new technologies such as Ethernet ring control and windage braking, carbon fiber, and magnesium alloy New materials such as nano-sound insulation have been successfully applied on this test train.
