Problems solved by technology

Although all road bureaus have strengthened safety protection measures for shunting operations, shunting accidents are still unavoidable
At present, shunting accidents caused by human factors occur from time to time. For example, when shunting operations or when locomotives leave and enter the warehouse, the operators mainly rely on the lookout to confirm the shunting signals on the ground. The interference of the conditions, and the accident that the shunting signal cannot be correctly identified
Therefore, once personnel make mistakes in operation, it will often cause dangerous accidents such as off-line, jamming, slipping, etc., or side conflicts, overturning, and even car crashes and fatal accidents.

Embodiment 1

[0076] A railway shunting signal safety early warning system, including a video data acquisition module, a video data preprocessing module, an image analyzer, a signal display screen, a voice prompter, a telecommunication 4G router and a video data storage module,

[0077] Described video data acquisition module collects the video data of 1-150m ahead of shunting;

[0078] The video data acquisition module includes a first video acquisition camera and a second video acquisition camera, and the first video acquisition camera is installed on the tops at both ends of the locomotive to collect long-distance video data in front of the train; the second video acquisition camera is installed In the middle of the two ends of the locomotive, collect video data at short distances in front of the train; select and collect video data at different distances in front of the train according to the speed of the train. In ordinary shunting or trains with a running speed of less than 160km / h, th...

Embodiment 2

[0095] A kind of data preprocessing method of video data preprocessing module described in embodiment 1, its steps are,

[0096] (1) According to the Retinex theory, establish the formula: I(x,y)=L(x,y)R(x,y),

[0097] Where I(x,y) represents the RGB image to be defogged, L(x,y) represents the light component, which refers to the low-frequency component in the image; R(x,y) represents the reflection component, which has nothing to do with the light effect , as long as it is the detailed information of the image;

[0098] (2) Use grayscale image for processing, convert RGB image I(x,y) into grayscale image I H (x,y),

[0099] (3) Use the Gaussian filter to estimate the illumination component L(x,y), and establish the formula:

[0100]

[0101] Among them, G is a Gaussian kernel with a size of M×N, and * represents a convolution operation;

[0102] (4) Calculate the reflection component R(x,y) through the Retinex principle, and establish the formula:

[0103] R(x,y)=I(x,...

Embodiment 3

[0112] The display signals of railway shunting operations in my country mainly have three colors: red, blue and white. The red light is the shunting protection signal for the branch line entrance that does not handle blockage and the end-type arrival and departure line in the station; the blue light is the prohibition signal for shunting operations in the station; the white light is the passing signal for shunting operations, so all The signal light color discrimination module directly judges the spatial position, size and type of the signal light in the video image, and the signal light color discrimination module judges the spatial position, size and type of the signal light in the video image.

[0113] A kind of method for judging the spatial position, size and type of the signal lamp in the video image of the signal lamp color discrimination module described in embodiment 1, its steps are,

[0114] (1) the video image that receives video data is divided into the grid of s ...

Abstract

The invention discloses a railway shunting signal safety early warning system. The system comprises a video data acquisition module, an image analyzer, a signal display screen, a voice prompter and atelecommunication 4G router. Video data can be transmitted to a railway management department through the telecommunication 4G router, and the system plays a crucial role in railway operation and maintenance, engineering construction, disaster prevention and reduction and public security maintenance. Meanwhile, the image analyzer adopts machine vision identification; intelligent video analysis technology, the method comprises the following steps: processing a front video image shot by a vehicle during advancing to obtain a signal lamp and incoming line information; the distance between the signal lamp and the locomotive is calculated in real time, relevant information is displayed through a signal display screen, and a voice prompter is used for carrying out proper voice prompt. The safetystate of the locomotive is comprehensively judged through the color and distance of the signal lamp and the running speed of the locomotive, and a voice prompter is used for voice prompt to guide a driver to drive safely, so that the purpose of safe operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of railway safety early warning, and in particular relates to a safety early warning system for railway shunting signals. The present invention also relates to a safety warning method of the railway shunting signal safety warning system. Background technique [0002] Railway transportation is an important industry to improve the level of transportation production and collectivization of people's materials. The rapid economic development has continuously promoted the growth of transportation volume, making railways play a pivotal role in the transportation industry. Among many types of railway work, shunting operation is an important link in the organization of traffic at railway stations. Along with the increase of transportation volume and the raising of railway speed, railway transportation accidents also emerge in an endless stream, have caused huge losses to the country and the people. Among them, the...
