System and method for accurately detecting track of water slide

Abstract

The invention discloses a system and a method for accurately detecting a track of a water slide. The system comprises a to-be-detected slide way, a carrier phase difference module and a skin raft; a mobile station of the carrier phase difference module is fixed to the geometric center of the skin raft; a fixed station of the carrier phase difference module is arranged outdoors, and the horizontalheight of the fixed station is larger than that of a starting point of the to-be-detected slide way; and the mobile station is in communication connection with a handheld terminal. According to the system for accurately detecting the track of the water slide, a movement track of the skin raft is detected through RTK, and the nominal precision is 5cm horizontally and 10cm vertically, so that the requirements of the measuring precision are met; and when a test is carried out in a glass fiber reinforced plastic pipeline, the difference between the number of received satellite signals and the outdoor environment is not large.

Description

technical field [0001] The invention belongs to the technical field of amusement facilities, and in particular relates to an accurate detection system and detection method for a track of a water slide. Background technique [0002] After the design of the water slide is completed, it is necessary to analyze the motion trajectory of the raft, and proceed to the next technical link only after meeting the design requirements. The traditional analysis of the motion trajectory of the skin raft is generally based on the judgment of practical experience combined with the analysis of rigid body dynamics based on CAE. Technical means cannot detect the accurate acceleration and motion trajectory of the raft at the inflection point of the slideway and other positions with high acceleration, so it is difficult to design a slideway with ideal acceleration. Potential safety hazards can be eliminated by reserving enough design space, which increases the input cost of equipment. [0003] I...

[0002] After the design of the water slide is completed, it is necessary to analyze the motion trajectory of the raft, and proceed to the next technical link only after meeting the design requirements. The traditional analysis of the motion trajectory of the skin raft is generally based on practical experience and CAE-based rigid body dynamics analysis. Technical means cannot detect the accurate acceleration and motion trajectory of the raft at the inflection point of the slideway and other positions with high acceleration, so it is difficult to design a slideway with ideal acceleration. It can eliminate possible safety hazards by reserving enough design space, which increases the input cost of equipment

[0003] In the prior art, a three-axis fiber optic gyroscope can also be used to detect the trajectory of the raft. The three-axis fiber optic gyroscope has high measurement accuracy, but its own weight exceeds 1KG, and the heaviest exceeds 4KG. After adding batteries and memory cards, the portability is not enough.

[0004] In the prior art, UWB can also be used to detect the movement trajectory of the raft. The accuracy of this solution is controllable, but it needs to meet the measurement range of the water slide. At least 8 fixed stations are required. The more fixed stations, the higher the measurement accuracy. Installation and position calibration The process is complex, and the signal is sensitive to occlusion
