Simulation Research on Speed Curve of High Speed Train Based on Object-Oriented Technology

The high-speed train speed control is the core content of the high-speed train control system. It is one of the key high-speed railway research technologies, which affects the transportation efficiency of the railway transportation system. It has theoretical and practical significance for its research. Due to the long modeling period and low code reuse rate during high-speed train speed simulation research, considering the train characteristics and geographical conditions, the highspeed train CRH3 EMU is the research object, which is more realistic. The motion and computer model of high-speed trains simulates the operation of vehicles in the high-speed train during the time-saving operation mode by using object-oriented technology as an example. It proves the correctness and effectiveness of the object-oriented technology simulation program. Provide a reference for subsequent research.

I. Introduction

Railway signaling system is a collection of technical measures and supporting equipment needed to realize traffic command, train operation supervision and management, which play an important role in ensuring the safety of train operation and improving the operational efficiency of railway transportation. The core of rail transit signal is the automatic train control ATC (Automatic Train Control) system, which consists of computer interlocking, automatic train protection ATP (Automatic Train Protection) and automatic train monitoring ATS (Automatic Train Supervision) and other subsystems [1], [2], [3]. The establishment of simulated train operation control system and simulated train operation mechanism in university laboratories is of great significance for subject research and classroom teaching. High-speed train speed control is the core content of high-speed train control system, and domestic scholars have done a lot of research on simulating high-speed train operation; their research mainly includes the following aspects: the application and simulation of fuzzy predictive control in automatic train driving system; through the study of the current third-party test platform for railroad signaling equipment [4]; the introduction of the research idea of software test management [5]; based on the interconnection Based on the integrated testing requirements of CBTC ATP system, the ground simulation environment was designed and implemented to realize the relevant functions of each part [6]; through reasonable planning, the simulation environment of the complete CBTC system was built to ensure the integrity of the whole CBTC system functions, which provides a reference for the construction of similar laboratories [7]; for the training of special interlocking functions of high-speed railways, it was proposed to realize the computer interlocking of high-speed railways through software simulation. For the training of special interlocking functions of high-speed railways, we proposed realizing the training program of computerized interlocking simulation of high-speed railways by software simulation, and carried out software development and implementation [8].
