High-speed rail sand table train control system

Abstract

A high-speed rail sand table train control system, including a simulated track and a simulated train, the simulated track includes at least 2 track sections and a control device and a ground signal machine located in the sections; the control devices have the same structure, including separately installed A frequency-shifting signal transmitter and a frequency-shifting signal receiver at both ends of the track section, the input end of the frequency-shifting signal receiver is connected to the analog track through a transmission line, and the output end is connected to the frequency-shifting signal transmitter of the next section through a transmission line connection, the control end is connected to the ground signal machine in this section; the simulated train includes an inductance coil, a small signal amplifier circuit, a frequency shift signal demodulator, a locomotive signal machine and a train traction system. The high-speed rail sand table train control system uses a frequency-shifting signal transmitter to send information to the track surface, uses a frequency-shifting signal receiver to demodulate the information, and controls the ground signal machine. The simulated train can receive frequency-shifting information from the track surface, and then control The locomotive signal machine lighting and train running speed, so as to truly simulate the railway scene.

Description

technical field [0001] The invention relates to a railway train control technology, in particular to a high-speed train sand table train control system suitable for signal transmission and reception in a high-speed rail sand table, locomotive signal machine lighting and train speed simulation control.

Problems solved by technology

[0002] With the rapid development of high-speed rail, high-speed rail signal technology is becoming more and more prominent as the core of high-speed rail train control. At present, major railway colleges and universities do not have high-speed rail sand table train control system, which is not conducive to the improvement of students' skills for railway colleges , affecting the quality of practical training in railway colleges and universities

In order to combine students' theory with practice, students need to carry out on-site practice, but because the railway site stipulates that interns can only watch, the effect of practice cannot meet the needs of teaching, therefore, railway colleges must be built to be suitable for the railway site equipment Professional experience and practice drill sites that meet the needs of practical teaching, but most of the current practice drill sites are only suitable for operation and driving related majors, and for signal workers, the parameters of the railway site need to be actually measured, so relevant and applicable train control system for high-speed rail

For the existing high-speed rail sand table train control system, most of them are related vehicle control devices designed by railway enthusiasts, without frequency shift parameters on the railway site, and there is no corresponding high-speed train train control technology
