Roller coaster track in-service detection system

Abstract

The invention relates to the technical field of recreation facility safety detection, and discloses a roller coaster track in-service detection system which comprises a track damage magnetic memory detection module, a track laser profile measurement module, a magnetic memory probe displacement detection module, an IMU trajectory tracking detection module, a data acquisition module, a data processing module and a data transmission module. The track damage magnetic memory detection module detects a magnetic signal of a measuring point on the track; the track laser contour measurement module detects a track contour through a laser contour sensor; the magnetic memory probe displacement detection module detects the displacement of a magnetic memory probe of the track damage magnetic memory detection module deviating from an initial position; the IMU trajectory tracking detection module obtains IMU signals of measuring points on a track; the data acquisition module performs data acquisition on detection data of each module; the data processing module stores and processes the collected data and sends the processed data to the cloud server. According to the invention, the track detection is more accurate, efficient, economical and safe.

Description

technical field [0001] The invention relates to the technical field of safety detection of amusement facilities, in particular to an in-service detection system of a roller coaster track. Background technique [0002] In recent years, many amusement parks or theme parks have been built all over the country. Roller coasters attract a large number of tourists because of their strong stimulation of the senses. However, as a large-scale amusement facility, the stimulation of centrifugal force, acceleration, and weightlessness that the roller coaster brings to tourists is due to its high-speed operation on the track. During long-term high-speed operation, periodic high loads will be imposed on the track due to roller coaster and tourist loads. It will lead to fatigue damage and deformation of the track. Once the track deformation of the roller coaster exceeds the allowable range or fatigue fracture occurs, it will lead to the derailment accident of the roller coaster, causing ...

Problems solved by technology

However, when using this method for inspection, it is necessary to design a separate inspection trolley, which is costly and cannot realize the in-service inspection of the track during the operation of the roller coaster; it is necessary to design inspection vehicles of different sizes for different specifications of the track, and the application range is narrow; Using CCD to detect the track gauge error is relatively large, which needs to be corrected by using an algorithm; using CCD to detect the track surface profile can only detect the damage on the track surface, but cannot detect the internal defects of the track, and the detection requires manual identification of defects, which is inefficient. Poor detection of microscopic defects

At the same time, the results of existing tests cannot be viewed remotely in real time
