Cargo weight counting device and ship cargo weight counting system

Abstract

The invention provides a cargo weight counting device which comprises an obtaining unit, a recognition unit and a processing unit. The obtaining unit is used for obtaining image data of water gauge scales corresponding to water lines obtained before and after ship unloading, the input end of the recognition unit is connected with the output end of the obtaining unit and used for recognizing water gauge scale values corresponding to waterlines obtained before and after ship unloading from the image data, the input end of the processing unit is connected with the output end of the recognition unit and used for controlling flight motion of the obtaining unit and determining the weight of cargos on a ship according to the water gauge scale values corresponding to the waterlines obtained before and after ship unloading, parameters of the ship and the density of water where the ship is located. The device can control the flight motion speed of the obtaining unit to rapidly and efficiently obtain and calculate needed data, the recognition unit can accurately and scientifically recognize the water gauge scale values corresponding to the waterlines obtained before and after ship unloading, and the problem that subjectivity exists in manual reading is avoided. The invention further discloses a ship cargo weight counting system which has the advantages of the cargo weight counting device.

Description

technical field [0001] The invention relates to the technical field of weighing, in particular to a cargo weighing device and a ship cargo weighing system. Background technique [0002] After the ship arrives at the destination, relevant departments need to weigh the cargo loaded on the ship. The principle of weighing the cargo loaded on a ship is as follows: obtain the water gauge scale corresponding to the water level line of the ship before and after unloading, and calculate the weight of the ship according to the two water scale scales before and after unloading, the parameters of the ship itself and the density of water. The weight of the loaded cargo. [0003] The existing technology is to manually calculate the weight of the cargo loaded on the ship. Specifically, because the overall volume of the ship is usually large, people cannot directly obtain the water scale corresponding to the current water level of the ship. After the ship enters the dock, People approach ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the prior art method of calculating the weight of cargo loaded on a ship requires the ship to enter the dock, and people take a boat to get close to the ship for reading, but it takes a long time for the ship to enter the dock, and the time period for reading the water gauge scale twice before and after unloading is long.
