Railway platform light curtain protection device combined with laser detection and control method thereof

Abstract

The invention discloses a railway platform light curtain protection device combined with laser detection. The railway platform light curtain protection device is characterized by comprising a virtualplatform door arranged on the edge of a platform and a safety detection device; the virtual platform door comprises light curtain stand columns, light curtain top beams between the light curtain standcolumns and a plurality of plasma light generators distributed on the light curtain top beams; the plasma light generators are used for emitting visible light beams to generate a continuous light curtain, and a virtual channel corresponding to a train door can be formed by selectively closing part of the plasma light generators to eliminate part of the light curtain. A light curtain replaces a traditional scheme that a platform door is arranged beside the platform, the protection device is arranged on the premise of not retreating or slightly retreating, the occupied width of the platform isreduced, and the requirement for the width of the platform is lowered; compared with a traditional platform door, the virtual light curtain can adapt to more vehicle types. The safety detection deviceadopts a laser scanning correlation device for dynamic scanning, the accuracy is high, the coverage is large, and the personnel safety and the driving safety of a platform side area are ensured.

Description

Technical field [0001] The invention belongs to the field of railway platform protection, and in particular relates to a railway platform light curtain protection device combined with laser detection and a control method thereof. Background technique [0002] In order to ensure the normal operation of railway trains and the safety of passengers, improve the waiting environment, and improve the comfort of passengers waiting, it is usually considered to install protective devices at the edge of the platform, such as platform doors. The platform door is a device installed on the rail side edge of the railway platform to isolate the platform area from the track area. When the train arrives, open the sliding doors for passengers to get on and off the train. [0003] When the train passes the station without stopping and the speed is relatively fast, it is necessary to install platform doors and other protective facilities to ensure the safety of passengers. [0004] The existing railway...

AI Technical Summary

Problems solved by technology

[0005] Problem 1: Mixed running of multiple models. Due to the variety of domestic railway models (CRH1A, CRH2, CRH5, CRH6A, CRH1, CRH3C, CRH380A, CRH380B, CRH380AL, etc.), the number and location of train doors are complex and different. The platform doors should be the same as the doors. One-to-one correspondence, traditional platform doors are difficult to adapt to multiple vehicle types at the same time

[0006] Problem 2: Even if the platform door matches the doors of various models through mechanical design, for complex working conditions where different vehicles arrive at the station at different times and there are special circumstances, it is difficult to meet the seamless connection between large passenger flow and high-density traffic. System requirements are extremely high

[0007] Problem 3: The width and span of the railway platform is limited, and the installation of platform door equipment affects the evacuation of passengers and the safe and fast passage

[0008] Question 4: Judging from the design of existing platform doors at home and abroad, when compatible with multiple vehicle types or meeting the high-speed crossing conditions of the main line, the platform doors are generally installed in the way of setting back platform doors

However, the retreat of the platform door will directly cause the platform to be widened, the line spacing will increase, and the investment will increase.
