FPGA (field programmable gate array) based ship anti-collision warning system

Abstract

The invention discloses an FPGA-based anti-collision warning system for ships, which includes a laser receiving module, a rotation control module, a signal conversion circuit module, an FPGA control module, an alarm module, a data input module, a liquid crystal display module, and a battery module; The laser signal output end of the module is connected with the laser signal input end of the signal conversion circuit module, the electrical signal output end of the signal conversion circuit module is connected with the electrical signal input end of the FPGA control module, and the alarm signal output end of the FPGA control module is connected with the alarm module's The alarm signal input terminal is connected, the rotation signal output terminal of the FPGA control module is connected with the rotation signal input terminal of the rotation control module, and the data output terminal of the data input module is connected with the data input terminal of the FPGA control module. The invention can detect the distance from the ship to the vicinity in real time and measure whether the bridge can be passed safely, thereby improving the reliability of the ship's navigation and reducing ship collision accidents.

Description

technical field [0001] The invention relates to an early warning system, in particular to an FPGA-based anti-collision early warning system for ships. Background technique [0002] Today, with the rapid development of the global economy, as an important means of transportation, ships carry a large amount of cargo transportation, and the safe navigation of ships is of great significance. However, in addition to the collisions between ships, there are also collisions between ships and reefs, submerged reefs, collisions between ships and bridges, etc. during navigation. With the continuous large-scale and professional development of modern ships, the increasing number of them leads to an increase in traffic density in water areas, and accidents such as collisions are prone to occur, resulting in huge casualties and property losses. [0003] In addition, there are some chemical tankers, oil tankers and other specialized ships carrying more and more dangerous goods, causing seri...

AI Technical Summary

Problems solved by technology

Ship-bridge collisions will cause serious consequences such as bridge damage, ship sinking, casualties, cargo oil leakage, environmental pollution, and long-term congestion of waterway transportation trunk lines. The manpower and material resources required for repairing or rebuilding bridges, dredging channels, and repairing ships are quite huge. Therefore, There is an urgent need for a ship collision avoidance warning system to avoid ship collision accidents
