Ship intelligent alarm system and ship

Abstract

The invention provides a ship intelligent alarm system and a ship, and relates to the field of ship navigation aiding. Information such as the positions, courses and navigational speeds of other ships is determined through a communication unit, and the information such as the position, course and navigational speed of the current ship is acquired through a data acquisition unit, and a control processing unit is used for calculating according to the two kinds of information; when the ship is in different navigation speeds, different early-warning conditions are used, and when the sailing states of other ships reach early-warning conditions, an alarm unit is controlled to give an alarm so that the ship can effectively avoid other ships; when the ships enter a port area and the ship density of a port is too high, the system automatically shuts off the alarm to avoid unnecessary disturbance; when the ships enter a specific water area, voice prompting is carried out through the alarm unit so that the sailors can effectively adjust routes, accidents are reduced, and the safety of the ships is guaranteed.

Description

technical field [0001] The invention relates to the field of ship navigation aids, in particular to a ship intelligent alarm system and a ship. Background technique [0002] my country is a big fishery country in the world. In 2010, the country's fishery population was 20.8103 million, of which 13.9921 million were employed in the fishery industry; it had 1.0656 million fishing boats, accounting for more than a quarter of the world's total; the total output of aquatic products accounted for the world's total output of aquatic products The proportion exceeds one-third; the total output value of the fishery economy is 1.28 trillion yuan, of which the fishery output value is 675 billion yuan, accounting for 9.3% of the agricultural output value. The development of fishery production is of great significance to ensuring national food security, increasing the income of farmers and fishermen, promoting ecological civilization, and safeguarding marine rights and interests. The prod...

Problems solved by technology

The avoidance of the AIS system only gives an indiscriminate alarm to the data of the ship

[0004] Moreover, based on the new data interaction of the AIS system, there are often cases where the ship name information cannot be displayed. There are two factors that cause this problem: one is the timeout refresh caused by the loss of the transmitted data packet, so that all the received information is refreshed To clear, the information needs to be re-received, resulting in the name of the ship not being displayed; secondly, because different types of AIS information have different update intervals, the static information update interval is 6 minutes, and the dynamic information depends on the change of the speed and direction of the ship, there are 2s, 5 report intervals of 31 / 3s, 6s, 10s, and 30s. Generally, the dynamic information is displayed immediately after receiving the dynamic information, while the ship name information is only displayed when the static information is received, resulting in that the ship name is often not displayed
