Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 As shown, the present invention utilizes at least three water level gauges to form a space array to form an array-type wave monitoring device. The device includes the following components: a fixed horizontal support 1 on which at least three high-precision water levels Count 2, 3, 4. The three water level gauges 2, 3, 4 are distributed in a triangle on the horizontal support 1, and because there is a common installation base of the horizontal support 1, it is ensured that the three water level gauges 2, 3, 4 are at the same level.

[0033] The three water level gauges 2, 3, 4 are all connected to the remote computer processing terminal 6 through the cable 5 and necessary signal conversion equipment. The wave signal collected by the water level gauge is sent to the computer processing terminal after collection and processing f...

Abstract

The invention relates to an array type wave monitoring device and a wave measurement method. The device comprises a horizontal bracket of a fixed device, the horizontal bracket is provided with at least three water level meters in triangular distribution, and the three water level meters are at a same horizontal height; and the three water level meters are connected with a computer processing terminal by transmission lines and a signal conversion device. The method is to calculate the times tau AB and tau AC of wave from the first water level meter to the second water level meter and the third water level meter by utilizing any water level meter to measure wave height and cycle and utilizing the three angled water level metes according to a cross-correlation time-delay principle, and according to tau AB and tau AC and distances and angles among the water level metes, wave direction, wave speed and wave length lambda is equal to c multiplied by T0 are calculated.

Description

technical field [0001] The invention relates to a wave monitoring device and method, in particular to a matrix wave monitoring device and a measuring method thereof. Background technique [0002] The measurement of wave parameters such as wave height, wave direction, wave period, wavelength, and wave speed has extremely important significance and application value for marine engineering construction, marine fishery production, marine transportation, marine environmental protection, marine scientific research and even marine national defense. [0003] Existing wave measurement methods include: acceleration measurement method, pressure method, wave surface measurement method, wave surface roughness inversion method, etc., among which all are indirect measurements except wave surface measurement method. Equipment based on acceleration measurement and water pressure measurement must be deployed in water, which is difficult to deploy, easy to lose, and high maintenance costs. Th...
