Appearance detection system and method of a vehicle signal machine

Abstract

The invention provides a system and method for detecting the appearance of a vehicle-mounted signal machine, wherein the system includes: a high-speed identification camera, a laser range finder, an image acquisition device and a controller; The bottom of one side; the controller is connected to the high-speed identification camera, laser range finder and image acquisition device, and is used to turn on the laser range finder at the first predetermined time to measure the distance between the signal machine and the signal machine after the high-speed identification camera recognizes the signal machine. The focal length of the image acquisition device is adjusted according to the distance information measured by the laser range finder, and the image acquisition device is turned on at a second predetermined time to collect image data of the signal machine. The invention can turn on the image acquisition device to collect the image data of the signal machine when inspection is required, prolonging the service life of the equipment; the focal length of the image acquisition device can be adjusted in real time according to the distance information measured by the laser range finder, and the accuracy of image acquisition can be improved.

Description

technical field [0001] The invention relates to the technical field of railway detection, in particular to a system and method for detecting the appearance of a vehicle-mounted signal machine. Background technique [0002] With the rapid increase in the operating mileage of high-speed railways and ordinary-speed railway lines, the inspection workload of signal machines has also greatly increased. The following questions: [0003] The accuracy of the inspection is low. Because the skylight time of the high-speed railway and the general-speed railway line is mainly at night, the lighting at night is poor, and it is prone to missed and wrong inspections, causing potential safety hazards. The inspection efficiency is low. An average of 3-5 kilometers of high-speed and ordinary-speed railway lines are inspected per hour. Hundreds of kilometers of high-speed and ordinary-speed railway lines take up a lot of human resources and inspection time. The risk is high, and there is a ce...
