Anti-collision alarming radar system and device for ships

Abstract

The invention discloses an anti-collision alarming radar system for ships, comprising a marine radar, an anti-collision alarming device and a three-port adaptor that connects a transmitter / a receiverof the marine radar with a display terminal and the anti-collision alarming device. The anti-collision alarming device comprises a display, an alarming apparatus, a data collecting board and a computer board, wherein the data collecting board is used for collecting detection signals, echo signals and bow signals from the radar to calculate the target distance and the angle and sending frame data formed by radar scan to a computer board; and the computer board is used for extracting the target point track data from the frame data to predict the future trend of target motion by associating and smoothing process via a track association algorithm and to evaluate and judge the risk level of the target in real time and then controlling the display and the alarming apparatus to display information and send the alarm signal. The invention further discloses an anti-collision alarming radar device for ships. The invention can be realized with low cost and is of great importance to ensure safetyof navigation of the ships.

Description

technical field [0001] The invention relates to a radar system, in particular to a fully automatic intelligent anti-collision warning radar system for ships. Background technique [0002] According to statistics, my country currently has as many as 280,000 fishing vessels engaged in offshore fishing, and the total number of offshore transport vessels has reached more than 400,000; moreover, the two types of vessels are mostly concentrated in merchant shipping lanes and nearby waters, resulting in dense ships in offshore waters , frequent ship collision accidents. Especially fishing boats, due to their small tonnage, naturally become the biggest victims in collision accidents, often resulting in shipwrecks and heavy losses. According to the national statistics of fishing boat collision accidents in 2007, a total of 318 collision accidents occurred, 210 ships sank, and 319 people died. Although most fishing boats are equipped with marine radar equipment, these radars are econ...

AI Technical Summary

Problems solved by technology

Although AIS can also provide auxiliary information to assist in collision avoidance, it is not effective for ships that are not equipped with AIS

Although the ship-borne VHF wireless telephone can conduct inter-ship dialogue, understand the information and status of other ships, and negotiate and avoid collisions, but due to the ambiguity and misunderstanding in the operator's language expression and communication, the speed of information exchange is slow and irregular, often The delay did not play a role in negotiating and avoiding collisions

[0007] Therefore, the above two systems are not suitable for offshore fishing boats, mainly because the system is complex and expensive

At present, the professional automatic anti-collision warning equipment that can be matched with the economical marine radar used by small and medium-sized ships is still blank
