System for measuring ship draft and river water level based on special micro wave 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 invention relates to a measurement system for ship draft and river water level, in particular to a ship draft and river water level measurement system with special reduced microwave amplitude and water gauge. Background technique [0002] The water level of rivers, channels, and reservoirs is very important hydrological data, and it is very important to measure the water level. [0003] The inclination test must be done after a new ship is launched, and the key step is to measure the draft of the ship when it is empty. Water gauge weighing is a common method for measuring the weight of goods in domestic and international trade for bulk, cheap and bulk goods transported by ships. The key link of water gauge weighing is the measurement of ship draft. So far, the simple visual method is still widely used to measure the draft of ships. Although a variety of measuring instruments for ship draft or river water level have been developed at home and abr...

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
