Closed-state detecting system and method for hopper car with bottom door

Abstract

The invention discloses a closed-state detecting system for a hopper car with a bottom door. The closed-state detecting system comprises an image processing unit and a positioning unit (3), wherein the image processing unit comprises a high-definition camera (4) and an image processing module (5); the image processing module (5) is used for realizing recognition for the faulted bottom door; the positioning unit (3) is connected with the image processing module (5) and comprises a photoelectric sensing module (32) and a control module (33); the control module (33) is used for counting the control signals so as to realize positioning for a carriage with the faulted bottom door. The invention also discloses a closed-state detecting method for the hopper car with the bottom door. The closed-state detecting system disclosed by the invention has the advantages that by adoption of the image processing technology, the door-closing fault points can be automatically recognized by high efficiency, and a positioning system based on a photoelectric sensing technology is used for positioning the fault points, so that operators can find the door-closing fault points quickly and accurately and thedetection efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of door closing detection, and more specifically relates to a door closing state detection system and method for a bottom-opening hopper vehicle. Background technique [0002] Bottom-opening hopper car is mainly used to transport bulk cargo, such as coal, grain, etc., on railway lines. After the vehicle arrives at the destination, the bulk cargo is unloaded to the conveyor belt in the middle of the track or in the bottom pit by unloading at the bottom. . The bottom-opening hopper car is widely used in domestic and foreign power plants and coal transportation lines due to its high coal unloading efficiency. [0003] Since the unloading port of the bottom-opening hopper car is located at the bottom of the car body, in order to prevent the bottom door mechanism from accidentally opening during transportation and leaking the goods onto the track, thereby causing accidents that endanger driving safety, existing ...

AI Technical Summary

Problems solved by technology

[0003] Since the unloading port of the bottom-opening hopper car is located at the bottom of the car body, in order to prevent the bottom door mechanism from accidentally opening during transportation and leaking the goods onto the track, thereby causing accidents that endanger driving safety, existing bottom-opening hopper cars are equipped with secondary locking mechanism

After unloading coal, the bottom-opening hopper car closes the door through the door-closing bumper switch installed beside the track. Generally, the door will be locked after closing. When the system fails, the hopper car cannot complete the door closing action, and the door closing fails. Driving on the track will cause serious damage to the vehicle body and fixed facilities along the line, and even threaten driving safety. Therefore, it is necessary to perform door closing detection on the bottom-opening hopper car to ensure that the closing action is completed.

At present, in China, inspectors use the naked eye to judge whether the bottom door is closed. The bottom door is located at the lower part of the car body. During the inspection, the operator needs to bend down and stand close to the bottom door to make a judgment. The judgment efficiency is low and the labor intensity is high. There are missed judgments, Misjudgment phenomenon, and low positioning accuracy
