High-speed rail sand table train control system

Abstract

Provided is a high-speed rail sand table train control system. The high-speed rail sand table train control system comprises a simulated track and a simulated train. The simulated track comprises two or more track sections, control devices arranged in the track sections and ground signal machines; the control devices have the same structures, each control device comprises a frequency-shift signal transmitter and a frequency-shift signal receiver which are arranged at the two ends of each track section respectively, an input end of the frequency-shift receiver is connected with the simulated track through a transmission line, an output end of the frequency-shift receiver is connected with the frequency-shift signal transmitter of a latter track section through another transmission line, and a controlling end is connected with the ground signal machine in the same track section; the simulated train comprises an inductance coil, a small-signal amplifying circuit, a frequency-shift demodulator, a train signal machine and a train traction system. According to the high-speed rail sand table train control system, the frequency-shift transmitter is adopted to send information to a rail surface, the frequency-shift receiver is used for demodulating the information and controlling the ground signal machines, the simulated train can receive frequency-shift information from the rail surface and control the train signal machine lighting and the running speed of the train, therefore, the real simulation of a railway site is achieved.

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
