摘要：
A traction calculation platform of high-speed train based on the braking curve of train control onboard equipment is designed for the compliance verification between block section length and train control system on railway passenger dedicated line. The web technologies, such as HTML, CSS, JavaScript, Vue.js, Node.js and Koa, are used to develop the B/S structure application platform, where the MySQL is used as the back-end database. The platform is divided into five functional modules, i.e., the basic data processing, the train operation simulation, the train tracking headway calculation, the block section validation and the statistical analysis. Particularly, the train operation simulation module is the core of the traction calculation platform, which is composed of infrastructure data, train dynamics model, the braking curve algorithm of train control onboard equipment and speed control. The braking curve algorithm of train control onboard equipment has the function of train overspeed protection, which generates the permitted speed and brake command according to the information of the movement authority and the train speed distance to realize the closed-loop processing of train operation simulation. The train control engineering data of the Beijing-Shanghai high-speed railway and CRH3A EMU parameters are selected for train traction calculation and the train tracking headway of high-speed railway is obtained, and the design length of block section is proved to meet the braking distance requirements of train control onboard equipment. Results show that the platform can be applied to the length compliance verification of block section and validating the matching between block section design and train control system. © 2020, Editorial Department of China Railway Science.
