Roller coaster track structure health monitoring system based on optical fiber sensing

Abstract

The invention discloses a roller coaster track structure health monitoring system based on optical fiber sensing, and the system comprises: an optical fiber grating sensor module which comprises a plurality of optical fiber grating strain sensors and a plurality of three-dimensional optical fiber grating acceleration sensors and is used for the real-time monitoring of key structure parameters; a fiber bragg grating demodulator which is connected with the fiber bragg grating sensor module through an optical fiber cable and is used for demodulating the wavelength signal generated by the fiber bragg grating sensor; and a monitoring host which is used for driving the fiber bragg grating sensor module, controlling demodulation of the fiber bragg grating demodulator and obtaining roller coaster track monitoring parameters through a communication network. The roller coaster track structure health monitoring system realizes lossless and anti-interference real-time monitoring of the roller coaster track, and has the advantages of being easy to install and maintain.

Description

technical field [0001] The invention relates to the field of roller coaster track structure detection, in particular to a roller coaster track structure health monitoring system based on optical fiber sensing. Background technique [0002] Roller coasters are typical equipment in large-scale amusement facilities, and the current domestic roller coasters are not equipped with early warning systems that can monitor their operating status, which brings great hidden dangers to the safe operation of roller coasters. The roller coaster belongs to the large-scale amusement facilities of the scooters, and is mainly composed of trains, tracks, columns, traction systems, braking systems, control systems, etc. Its working principle is: after the train is lifted by the chain to the highest point of the track, the train will automatically disengage the chain, slide freely along the track under the action of gravity, and finally return to the platform after being braked. [0003] With th...

Problems solved by technology

[0004] But to prevent these accidents from happening, it is far from being able to solve the problem just by relying on the attention of relevant departments and managers.

Through investigation and research, it is known that the damage and deterioration on the roller coaster track is the main cause of safety accidents. However, due to the continuity of production and economic considerations, it is impossible to achieve long-term real-time monitoring of the overall operating status of the roller coaster track.

Moreover, it is uneconomical and unrealistic to maintain the roller coaster track too frequently and blindly. Moreover, if the treatment method is unreasonable, it will cause more serious damage to the track and even produce some new defects.
