specific Embodiment approach 1

[0042] Specific implementation mode one: combine figure 1 Describe this embodiment, a kind of truck wheel diameter size dynamic detection device described in this embodiment, the detection device includes a vision module 1 and a control processing module 2;

[0043] The control processing module 2 is used to obtain the driving speed of the passing vehicle and the wheelbase of the front of the vehicle, and is also used to judge whether the passing vehicle is a truck, and if it is a truck, send a control signal; otherwise, do not send a control signal; Receive the image information, analyze and process the image information, and calculate the wheel diameter;

[0044] The vision module 1 is configured to receive a control signal, and collect images of the wheels of the truck according to the control signals to obtain image information.

[0045] In this embodiment, the visual module 1 is placed on the outer side of the rail 5 at a lateral distance of 50 cm from the rail 5, the ve...

specific Embodiment approach 2

[0046] Embodiment 2: This embodiment is to further limit the dynamic detection device for the diameter of a truck wheel described in Embodiment 1. In this embodiment, the control processing module 2 includes a wheel sensor 2-1, a control industrial control machine 2-2, control box 2-3 and acquisition industrial computer 2-4;

[0047] The control industrial computer 2-2 and the acquisition industrial computer 2-4 are respectively arranged in the control box 2-3;

[0048] The wheel sensor 2-1 is arranged on the side wall of the rail 5, and is used to obtain the driving speed of the passing vehicle and the wheelbase of the front;

[0049] Control the industrial computer 2-2, for judging whether the passing vehicle is a truck, if it is a truck, then send a control signal; otherwise, do not send a control signal;

Abstract

The invention discloses a truck wheel diameter dimension dynamic detection device and a detection method, relates to a railway truck wheel detection technology, and aims to solve the problems of low efficiency, time consumption and relatively large error of an existing manual detection method. The control processing module is further used for obtaining the running speed of a passing vehicle and the wheel base of a vehicle head to determine whether the passing vehicle is a truck or not, and if yes, sending a control signal, or otherwise, not sending the control signal; the processor is also used for receiving the image information, analyzing and processing the image information and calculating the wheel diameter; the vision module is used for receiving the control signal and collecting images of wheels of the truck according to the control signal to obtain image information. The beneficial effects are that the measurement precision is high and the real-time performance is strong.

Description

technical field [0001] The invention relates to a railway wagon wheel detection technology. Background technique [0002] The diameter of the truck wheel is an important parameter of the status data of the truck wheel. Due to the large difference in the diameter of the truck wheel of different models, it is difficult to measure directly with ordinary measuring tools; at present, the measurement of the truck wheel is still in the static measurement stage. Measurement is carried out at the workplace, and manual measurement is used, and manual measurement has problems of inefficiency, time-consuming, and large errors, which can no longer meet the fast, accurate, and automated detection requirements of modern railways. With the increasing number of trucks, the existing manual measurement methods can no longer meet the basic requirements of the diameter of truck wheels. Contents of the invention [0003] The purpose of the present invention is to solve the problems of ineffici...
