Anti-collision and early-warning system of railway vehicles

Abstract

The invention provides an anti-collision and early-warning system of railway vehicles. The system is composed of a speed collecting module, an inertia avigation module, a GPS (Global Position System) module, a parameter selection switch module, a display module, a sound module, a data storage module, a wireless network transmission module, a data processing and analyzing software module and the like, wherein the speed collecting module is used for collecting a frequency signal of the vehicle speed; the inertia avigation module is used for acquiring the changes of speed and direction of the railway vehicles entering into a tunnel; the GPS module is used for acquiring location, speed, direction and standard time of the vehicles; the display module is used for displaying speeds, directions, lines, distances and collision residual time information of the vehicle and the other vehicles; the sound module is used for safely alarming; the data storage module is used for storing full-route data in a driving process of the rail vehicle so as to be convenient for subsequent analysis and treatment; the wireless network transmission module is used for realizing real-time transmission of data; and the data processing and analyzing software module is used for analyzing and processing the information and judging whether a collision accident happens or not, as well as performing the corresponding early-warning treatment.

Description

technical field [0001] The invention relates to the field of rail vehicle operation safety, in particular to a rail vehicle operation positioning wireless detection and early warning system. Background technique [0002] Rail vehicles are one of the important components of existing transportation. Their large and fast passenger and freight volumes are one of the most important characteristics of rail vehicles. Therefore, their operating safety is very important. Once a major accident (collision) occurs Will directly affect the safety of life and property. Therefore, during the operation of rail vehicles, it is necessary to prevent major accidents (collisions) and ensure the safety of rail vehicles. The rail vehicle anti-collision warning system monitors various parameters such as the position and speed of the rail vehicle during operation, and sends these parameters of the rail vehicle through wireless technology. If there is another rail vehicle within a certain distance, ...

Problems solved by technology

However, this type of system also has obvious shortcomings: this type of system needs to be combined with the train control system, and it requires many links, especially the communication network along the railway line. The train needs to rely on the ground communication and control system during operation, so it is not suitable for independent Judgment, inconvenient to use and expensive, not suitable for loading general rail vehicles, especially line maintenance vehicles
