Rail Transit Turntable Conversion Equipment Status Perception and Intelligent Operation and Maintenance
Key technologies and applications
01
Introduction to the award-winning achievements
This project starts from three aspects: state perceptibility under complex conditions of switch conversion equipment, fault diagnosis under multi-source noise, and adaptability of operation and maintenance in mutable environments, forming an sensor technology system for intelligent operation and maintenance of switch conversion equipment, realizing all-round and multi-dimensional state monitoring of switch conversion equipment such as mechanics, optics, and electricity. It independently innovated the key technologies for intelligent operation and maintenance of rail transit switch conversion equipment, greatly reducing the operating costs of ; it pioneered the complete system of comprehensive monitoring of switch conversion equipment, realizing independent innovation of comprehensive monitoring and operation and maintenance technology and management model of turnout switch conversion equipment. The overall results have reached the international leading level and have been applied to 27 urban rail lines in 18 railway bureaus, 15 cities in my country, and multiple "Belt and Road" national lines. The number of turnout conversion equipment failures has dropped by more than 15% annually, supporting the safe operation of many major national railway projects such as Sichuan-Tibet Railway (Lalin Section), Beijing-Zhangjiakou High-speed Railway, and has gone abroad to serve the railway construction of "Belt and Road" countries such as Hungary, Serbia , and achieved huge social and economic benefits.

Laser multi-degree of freedom error for CNC machine tools simultaneously measured
Key technologies and applications
01
Introduction to the award results
oriented to "how to improve the accuracy of CNC machine tools " national major needs Looking for the two prominent problems of existing CNC machine error measurement instruments with "incomplete measurement, unfast measurement, and inaccurate measurement, and monopolized by European and American countries", the project proposed the principle of 42 geometric error instruments for direct laser measurement of five-axis CNC machine tools, fast automatic measurement method for geometric errors of 21 CNC machine tools, and the simultaneous measurement method and principle of linear axis/rotary axis/spindle multi-degree of spindle-axis coupled dual-frequency lasers based on single polarization-maintaining fiber; conquer key technologies such as light drift common path compensation, 18-error single target lens sensitivity, and precise steering positioning of space light rays. ; Solve problems such as the polarization direction control of the orthogonal polarization laser transmission of a single fiber, the instrument's own error compensation and the unified measurement model of different types of CNC machine tools. For the first time, it has developed a 42-item geometric error instrument for laser high-precision direct measurement of five-axis CNC machine tools with complete independent intellectual property rights. It has significant advantages such as complete measurement parameters, high comprehensive measurement accuracy, high measurement efficiency, and no blind spots in measurement. It has been applied in the high-end equipment manufacturing of , aerospace and other industries, and has achieved significant social and economic benefits. He has obtained 3 US patents, 2 European patents, 512 Chinese invention patents, and published more than 60 academic papers. Through the scientific and technological achievements identification of in the Chinese Instrument Society, it is at the international advanced level. Among them, the simultaneous measurement technology of linear shaft/rotating shaft six-degree of freedom error and the 42 error laser direct measurement technology of five-axis CNC machine tools is at the international leading level.
