Aerospace High-speed Rail Obstacle Avoidance Radar Launches First Data Acquisition in Xian, Shaanxi

[China Instrument Network Instrument R&D] Recently, 25 high-speed rail obstacle avoidance radar test teams of the China Aerospace Science and Industry Second Institute (CAST) went to Shaanxi Xi'an High-speed Railway Dongju to carry out the first test data collection. After a week of data collection and analysis processing, the experimental team acquired a large number of The real and effective result data provides effective data support for the subsequent formal product development.

High-speed rail obstacle avoidance radar was developed to ensure the safety of high-speed trains at night when entering and leaving the warehouse. It uses a combination of millimeter-wave radar and visible light camera detection system to work around the clock. It automatically detects and pre-empts obstacles such as trains, gates and pedestrians in front of the track. , inform the driver of parking.

The high-speed trains are mostly carried out at night and in the early hours of the morning, and currently the operators of the station are manually driving the track manually. Due to poor lighting conditions at night, fatigue of personnel and lack of driving experience of the driver of the station, there have been many accidents such as train collision and collision of the train with the gate and pedestrians.

High-speed rail equipped with obstacle avoidance system can effectively solve the occurrence of such problems. When carrying out warehouse operations, obstacles in front of the train can be automatically detected and alarmed in time to remind drivers to stop and avoid collisions. At present, there are no such products in China.

After the test team entered the Xi'an high-speed railway car section, in accordance with the principle of efficient work, completed the test equipment state self-test work in a relatively short period of time to ensure that the test equipment and the test product status is normal.

This test is completely based on the time schedule of the trains entering and exiting the high-speed train section of Xi'an High-speed Railway. The test team members finished the test at 2 o'clock in the morning, and they were very hard. In order to obtain satisfactory test results, the test team, defying the hardships, compared the collected data one by one and conducted detailed analysis to strive to obtain the most valuable test data.

During the test period, the participants also often conducted technical exchanges with users of the high-speed railway segment, conducted a comprehensive analysis of the main features of the product at the current stage, and detailedly introduced the functional indicators of the tested product in conjunction with the current test situation, and technically enabled the user Deepen the impression of the product, and at the same time demonstrate the technical strength of the project where 25 is located, laying a good foundation for cooperation in the follow-up product development and testing.

High-speed rail obstacle avoidance radar can greatly reduce the risk of collision between the EMU and EMU, EMU and rail obstacles. Finally, the formal product test is successful, and the products will be popular throughout the country and have good development prospects. The success of this test has effectively verified the reliability of 25 developed products, and has broad space for development in this field.
