A ship draft and river water level measurement system with special shrinking amplitude and water gauge

Abstract

The invention discloses a system for measuring ship draft and river water level based on special micro wave amplitude and a water gauge, belonging to the measurement field of the ship draft and the river water level and solving the technical problem that a measurement field video image comprising high-precision ship draft or river water level data can be displayed in real time by just using one miniature video picture. In the system, a technology of displaying the average height of irregular wave surfaces, a special micro technology of wave amplitude and ship water gauge maker or river water gauge, a video image monitoring system technology, an automatic tracking and shooting target technology of miniature camera equipment and the like are mainly adopted. The system has the advantages that visual, real, objective, just, clear and high-precision measurement data and measuring field live action which can be put on records is provided in real time by the video image and can be transmitted outside. The system has low cost, is simple and practical, is convenient to operate, carry and maintain and is energy-saving and environmentally-friendly, and the automatic measurement of the ship draft and the water levels of the river and the like is easily achieved.

Description

Technical field [0001] The present invention involves a measurement system for ships and river water levels of ships, especially the water and river water level measurement system that involves a special reduction amplitude and water ruler. Background technique [0002] The water level of rivers, channels, and reservoirs is very important hydrological data. Measurement of water level is very important. [0003] After the new ship is built, it is necessary to do a tilt test. The key step is to measure the water when measuring the state of the ship.The weight of the water ruler is the method of measured the weight of cargo in domestic and international trade to measure the weight of cargo transportation, cheap, and bulk goods.The key link of the water ruler is the measurement of water eating water.So far, simple visual inspection methods are still widely used for measurement of shipping.Although a variety of ships that have developed water or river water levels have been developed ...

AI Technical Summary

Problems solved by technology

The instrument is small in size, light in weight, and simple in structure, and can effectively eliminate the influence of waves on measurement accuracy, but its shortcomings are: poor practicability, because it does not use video image monitoring system technology, etc.

[0007] But its shortcomings are: the measurement accuracy is not high enough, the mechanism is relatively complicated, and the investment is large

Its disadvantages are: firstly, the error of the measurement result is the same as that of the visual method, and the accuracy is low; secondly, because the area of ​​the video screen that completely expresses the real scene of the measurement site must be large enough, resulting in huge equipment, complicated mechanism, high investment, and cumbersome operation, it cannot be realized. automated measurement

The reasons are as follows: 1. The utility model patent did not take technical measures to eliminate the impact of waves; 2. It did not take technical measures to "specially reduce" the wave amplitude; 3. miniaturization technology
