The Design of Wave Height Standard Device in the WTTVS and its Error Analysis

Abstract:

To make up the shortage of the existing calibration equipments of the wave measurement instruments, the WTTVS is designed, and the design of the wave height standard device as a subsystem of the WTTVS is introduced in this paper. The subsystem consists of two invar leveling staffs, a laser range finder and an incremental encode, in which the invar leveling staffs and the laser range finder are used to calibrate the encode. At the same time, the uncertainty of the subsystem is evaluated. As the result, the uncertainty is 3.48mm (confidence probability is 99%), which proves the feasibility of the design.
