Railway phase-sensitive track circuit practical training platform

Abstract

The invention provides a railway phase-sensitive track circuit practical training platform. The platform uses the integrated structure design and comprises an upper computer, a fault setting unit, a miniature power screen, a combined circuit and outdoor equipment. The outdoor equipment comprises a track transformer and a steel rail. The upper computer is used for practical training operation. Thecombined circuit is used for simulating controlling the outdoor equipment. The fault setting unit is used for fault setting or fixing. The miniature power screen is used for providing a track power supply, a local power supply and the working power supply of the internal circuit of the practical training platform. According to the practical training platform, two segment track circuits are established to be consistent with the site so that real simulation of the site fault of the railway can be performed, the function of manual adjustment of voltage and automatic voltage stabilization can be realized, free switching of microelectronic and relay phase-sensitive track circuits can be conveniently performed, fault simulation of two phase-sensitive track circuits can be realized, fault settingand fixing are completed on the upper computer, and thus the teaching efficiency is high and the requirements of the railway vocational colleges for experimental and practical teaching of the phase-sensitive track circuit can be met.

Description

technical field [0001] The invention relates to a railway teaching and training equipment, in particular to a railway phase-sensitive track circuit practical training platform suitable for technical training of personnel in higher vocational colleges, railway enterprises and institutions, and rail transit enterprises. Background technique [0002] With the further development of my country's high-speed railway and urban rail transit, phase-sensitive track circuits are widely used in rail transit. Phase-sensitive track circuits mainly provide train occupancy inspection and rail integrity inspection functions for railway sites, and 25Hz is mainly used on national railways. The main purpose of using 25Hz for the track circuit is to avoid the 50Hz current interference of the locomotive traction. In urban rail transit, since most of the subway track circuits use DC for locomotive traction, there is no traction current interference, so 50Hz or 25Hz is used. [0003] Due to the impo...

AI Technical Summary

Problems solved by technology

[0005] 1. During the fault simulation, the circuit is always cut artificially, and the relay is frequently plugged and unplugged, the teaching efficiency is low, and even the equipment is damaged;

[0006] 2. As far as schools are concerned, talent training must be connected with enterprises, and a set of equipment cannot be used for two types of phase-sensitive track circuits;

[0007] 3. Railway site personnel abide by the principle of three immobility, and cannot operate the equipment at work, and the improvement of skills is limited;

[0008] 4. The output voltage of the power panel on the railway site is fixed, and the overvoltage and undervoltage conditions cannot be simulated
