Wave height measurement device and method used for ice-water mixing environment

Abstract

The invention provides a wave height measurement device and method used for an ice-water mixing environment. The device comprises ultrasonic sensors, laser emitters, a camera and a data processor, wherein the ultrasonic sensors and the laser emitters are fixed on the steel bracket of a ship; the ultrasonic sensors are arranged by being vertical to the water surface and keep a preset safe distancewith the water surface; and the laser emitters and the camera are independently fixedly arranged on the preset position of the steel bracket, wherein the preset position guarantees that reflected laser can be received by the high-definition camera when the laser emitted from the laser emitters are in contact with an ice surface. The system adopts ultrasonic non-contact measurement and overcomes the problem that a traditional measurement method can not measure the ice-water mixing environment. Since the ultrasonic sensors are not in contact with the ice-water mixing environment, the influence of original wave height measurement equipment on an experiment is avoided, the device disclosed by the invention is slightly affected by the environment, the defect that an experiment instrument is likely to wear and tear is overcome, high measurement accuracy is guaranteed, and an experiment device can be easily installed.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a wave height measuring device and method for an ice-water mixed environment. Background technique [0002] In ship and ocean engineering experiments, the measurement and observation of waves is one of the important research methods. At present, there are many devices and methods for measuring wave height. The commonly used wave measuring devices are contact type, mainly including resistive wave height sensor and capacitive wave height sensor. However, the main disadvantage of this type of sensor is that the resistance or capacitance is greatly affected by the environment, and the measurement accuracy is not high, especially when it is used to measure the environment where ice and water are mixed. Since the contact measurement equipment is in contact with the measured water surface during measurement, Therefore, the equipment is easily damaged, and the contact measurement equip...

Problems solved by technology

However, the main disadvantage of this type of sensor is that the resistance or capacitance is greatly affected by the environment, and the measurement accuracy is not high, especially when it is used to measure the environment where ice and water are mixed. Since the contact measurement equipment is in contact with the measured water surface during measurement, Therefore, the equipment is easily damaged. At the same time, the contact measurement equipment will also hinder the movement of ice cubes, so it cannot measure the environment where ice and water are mixed.
