Abstract

The invention discloses a high-speed image detection system for an underground railway. The system is applied to the railway and is characterized by comprising a wheel, a light source and a high-speed camera which are sequentially arranged above the railway, wherein the light source is a laser light source, a photoelectric encoder is arranged in the wheel and connected with a signal processing circuit, the signal processing circuit is connected with the high-speed camera and connected with a PC (personal computer) connected with a GPS (global positioning system), and the irradiation angle of the high-speed camera corresponds to the light source. The high-speed image detection system for the underground railway can meet automatic underground tour-inspection requirement.

Description

technical field [0001] The invention relates to a subway track high-speed image detection system. Background technique [0002] At present, subways in cities have high operating density, large passenger flow, and closed environments, which have extremely high requirements for operational safety; in the operation of subways, the impact and vibration of vehicles on railway tracks increase sharply with the increase of vehicle speed. No, it is directly related to the safety of the operating vehicles, and also to the safety of the people carried on the vehicles. [0003] In order to ensure the normality of the railway track, it is necessary to check the condition of the track every day, so as to detect abnormalities such as damage, fracture, and dislocation of the track in a timely manner. The manual inspection method of the subway track is time-consuming and laborious. There is no corresponding automatic inspection system. Contents of the invention [0004] The technical pro...
