shipboard communication and interconnection (Manno 2015). Yingjun Zhang’s
team from Dalian Maritime University divided the technical framework of
unmanned ships into three parts: ship terminal autonomous navigation system,
high-performance maritime communication system and shore-based support system
(China Ship News 2015). Ship terminal autonomous navigation system is the core,
which involves intelligent perception, intelligent decision-making and reliable
implementation of decision-making technology. High-performance maritime communication system is responsible for transmitting information and instructions
between ships and shore, involving data compression technology, intelligent routing
technology and marine communication network security technology. Shore-based
support system includes monitoring center and information support center, involving
telemetry and remote control, complete information real-time push and intelligent
processing technology (Liu et al. 2016).
3.1 Information Perception Technology
Ships information perception refers to a technical means by which a ship can obtain
all kinds of information about itself and its surrounding environment based on a
variety of sensing equipment, sensing network and information processing equipment, so that the ships can navigate more safely and reliably. Ships perceived
information can be divided into its own state information and surrounding environment information. Its own state information includes the state information of various
equipments in the engine room, bridge and cargo compartment of the ship, as well as
the navigation position, speed, heading and other navigational state information of
the ships. It mainly relies on the existing pressure, temperature, speed, liquid level
and other sensors, and the sensing means are relatively mature. Surroundings around
information including ship and around obstacles, meteorological condition, water
depth, video monitor, audio monitor information, the flow speed and direction,
AIDS to navigation location, navigable areas, etc., which rely on AIS, maritime
radar, video cameras, laser sensor, laser radar sensor, a wind speed sensor, the
direction of the wind sensor, acquisition equipment, log, the depth of the water
meter, visibility voyage data recorder system (VDR), electronic chart (electronic
navigation chart) interaction information for vessel and shore, involved in the
process of perception between signal sort is more, the large amount of data and
information redundancy and conflict problems. It is worth further study (Burmeister
et al. 2014).
3.2 Communication Navigation Technology
Communication technology is used to realize the information interaction between
various systems and equipment on ships, as well as between ships and shoreline
stations, ships and navigational aids. Common modes of communication mainly
