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 electric ship draft monitoring system, which relates to a ship draft monitoring system. The invention is formed by a slave which is equipped with four electric draft scales, a system host arranged inside a cockpit and a RS485 bus. The system host comprises a microprocessor (100) and external memory storages (600), clock circuits (200), keyboard circuits (300), liquid crystal display circuits (400) and audible and visual alarm circuits (700) which are respectively connected with the microprocessor (100). A first slave (800), a second slave (900), a third slave (1000) and a fourth slave (1100) which are respectively arranged on port forward, starboard forward, port aft and starboard aft are respectively connected with interfaces of host microprocessor (100) through the RS485 bus and interface circuits (500). The invention is capable of automatically collecting the ship draft information, providing the corresponding technical support for the reasonable loading and navigation of the ships. The invention has the advantages of high measuring precision, swift control, reliable communication and good real-time, and can be widely used for the draft monitoring of various ships in rivers and seas.

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...
