Problems solved by technology

[0002] For a long time, the ship load calculation of my country's freight transportation has been mostly done manually, especially the calculation of coal, sand, ore and other cargo sources is troublesome and the accuracy is not high. Improper, especially the cargo owner's serious inaccurate (concealed) declaration of the weight of the cargo will easily cause the ship's imbalance and stability decline, which will not only affect the ship's navigation status, but may directly threaten the ship's navigation safety in serious cases

Abstract

The invention discloses an electronic ship draft monitoring system, and relates to a ship draft monitoring system. The present invention is composed of a slave machine equipped with four electronic draft gauges, a system host in the cab and an RS485 bus; the system host includes a microprocessor and an external memory connected to the microprocessor, a clock circuit, a keyboard circuit, and a liquid crystal display circuit, sound and light alarm circuit; the No. 1, No. 2, No. 3, and No. 4 slaves located on the left front, right front, left rear, and right rear sides of the ship are respectively connected to the serial port of the host microprocessor through the RS485 bus and the interface circuit. The invention can automatically collect ship draft information, and provide corresponding technical support for reasonable loading and navigation safety of ships; it has the advantages of high measurement accuracy, flexible control, reliable communication, and good real-time performance, and can be widely used in various types of rivers, lakes, and seas. Draft monitoring of ships.

Description

technical field [0001] The invention relates to a ship draft monitoring system, in particular to a ship draft monitoring system based on a planar capacitive electronic draft scale. Background technique [0002] For a long time, the ship load calculation of my country's freight transportation has been mostly done manually, especially the calculation of coal, sand, ore and other cargo sources is troublesome and the accuracy is not high. Improper, especially cargo owner's serious inaccurate declaration of the weight of the cargo (concealment), will easily cause the ship's imbalance and stability decline, which will not only affect the ship's navigation status, but may directly threaten the ship's navigation safety in severe cases. Contents of the invention [0003] The present invention aims at providing an automatic ship electronic draft monitoring system aiming at the above disadvantages. [0004] Technical scheme of the present invention is: [0005] It consists of a slav...
