The maritime information warfare platform does not include ()?

1. Including. The surface ships of the information-based maritime combat platform include amphibious ships. The information-based maritime combat platform mainly refers to the parts other than the weapon system, such as naval combat ships and naval combat aircraft, helicopters, amphibious armored vehicles, etc. operating at sea.

2. The information warfare platform mainly includes maritime, air and land combat platforms. The information-based combat platform refers to the weapon carrier equipped with a large number of electronic information equipment, including the information-based maritime combat platform, the information-based air combat platform and the information-based land combat platform.

3. Amphibious armored vehicles and other parts other than the weapon system. According to the query of Sohu News. Sea combat is the basic form of contract attack of various types of navy. The main task is to annihilate the enemy's combat ships and weaken the enemy's combat capability. The main feature of the offensive maritime combat ship formation battle is that the battlefield situation changes dramatically and the fighter is not easy to capture.

The role and significance of protecting marine ecosystems

The ocean has a powerful regulating role in climate. Coastal areas are the most suitable for human habitat on earth. Since ancient times, human beings have consciously chosen areas close to the ocean. Settlement, the population in coastal areas is now increasing explosively, and the population in some areas has exceeded the local population capacity limit.

Through the marine protected area, the original appearance of the natural environment and natural resources can be completely preserved; it can protect, restore, develop, produce and reproduce biological resources, preserve the diversity of biological species, and eliminate and reduce the adverse effects of man. Therefore, the rise of protected areas protects the marine environment for human beings and Its resources have opened up new ways.

In general, coastal ecosystems play an extremely important role in maintaining the ecological balance of ocean and land, protecting biodiversity, maintaining water quality, and providing leisure and economic value. Therefore, it is of great significance to protect and manage the coastal ecosystem.

This interaction helps to maintain the balance of the ecosystem and ensure the survival and development of various organisms. Therefore, the protection of marine and aquatic organisms is of great significance to maintaining ecological balance. Biodiversity: Marine and aquatic organisms are one of the richest sources of biodiversity on earth.

What kind of system is the Global Ocean Observation System?

Description: Global Ocean Observation System(GOOS) is an international cooperation system. Its main task is to apply a variety of technical means such as remote sensing, surface and subsusum surface observation, collect and process coastal, shelf waters and world ocean data for a long time and continuously, and open observation data and related data products to countries around the world.

The Global Ocean Observation System () is initiated and organized and implemented by the following four international organizations: Intergovernmental Oceanographic Commission (IOC), the World Meteorological Organization, the Council of the International Union for Science and the United Nations Environment Program. The GOOS project office is located at the IOC headquarters in Paris.

The establishment of the seabed observation network is a global detection system. Countries can share the data and research results of the seabed observation network, which further deepens the cooperation and exchange between countries. In addition, the seabedThe observation network is not only important in scientific research, but also can be used in the fields of marine safety, fisheries, tourism and resource development.

Submarine exploration is a way to directly observe the marine environment through underwater submarines. The advantage of this method is that it can go deep into the bottom of the ocean for observation and obtain more refined marine data.

Offshore traffic observation mainly includes six methods: latitude and longitude, radio navigator, radar, visibility observation, ship automatic identification system (AIS) and nautical positioning system. The details are as follows: Latitude and longitude meter: Use the latitude and longitude meter to measure the current longitude and latitude of the ship, so as to facilitate the crew to determine the position of the ship.

Classification of mobile communication system

Classification of mobile communication system can be classified according to its application.The maritime satellite mobile system is mainly used to improve maritime rescue work, improve the efficiency and management level of ship use, and enhance maritime communication services and wireless positioning capabilities.

Satellite mobile communication. Using satellite forwarding signals can also realize mobile communication. For on-board mobile communication, equatorial fixed satellites can be used, and for handheld terminals, it is more advantageous to use multi-constellation satellites in medium and low orbits. ( 4) Cordless telephone.

The mobile communication system consists of two parts: the space system and the ground system. Ground system: refers to satellite mobile radio stations, antennas, checkpoint stations and base stations. Since the birth of the mobile communication system in the 1980s, it will go through roughly five generations of development by 2020, and by 2010, it will transition from the 3rd generation to the 4th generation (4G).

Mobile communications is a communication method used between mobile users and fixed-point users or between mobile users. One or both parties to the communication are in motion. Mobile communication includes land, sea and air communication, and the frequency bands cover low frequency, medium frequency, high frequency, very high frequency and ultra-high frequency.

Special mobile communication; according to the activity range of the mobile station, there are land mobile communication, sea mobile communication and aviation mobile communication; according to the usage, the commonly used are mobile phone, wireless paging, cluster dispatch system, leakage cable communication system, cordless telephone, centerless location mobile communication system, Star mobile communication system, personal communication.

How does the nautical simulator reduce the cost of crew training

So many ships can be trained after meeting each other. The confrontation training between the crew members, such as avoiding collisions, doing some more professional operations (training) such as encounters (betwee ships), avoiding, chasing, etc.

First of all, before participating in the simulator training, we require students to arrange for a single training room exercise, such as power equipment disassembly, power equipment operation, ship power station operation, ship electrical technology and other training, and have a certain emotional understanding of the basic structure and operation methods of the cabin equipment, and the whole cabin Have a certain understanding.

The emerging low-cost desktop CBT technology based on the Windows operating system will certainly form a strong support for nautical practice teaching.

A: The ships and crew members purchased in the mall are common to all character archives, but the props used are only valid for each archive of the current character, and other characters are not.

What functions should a qualified warehousing management system have?

1. Inventory management: Support automatic replenishment. Through the automatic replenishment algorithm, it not only ensures the inventory of picking noodles, but also improves the utilization rate of warehousing space and reduces the probability of cellularization of cargo space. At the same time, it is also necessary to have the functions of inventory inquiry, inventory quantity warning, shelf life warning, first-in, first-out and other functions to achieve the goal of reasonable inventory control.

2. Storage function The warehousing function is a very convenient software that can improve the efficiency of warehouse management.After all products are labeled, they only need to be scanned with a data collector to complete the warehousing work when the products are warehoused.

3. First of all, a qualified warehousing management system should be able to provide a perfect data interface with the enterprise's ERP system, and also provide hardware interfaces, such as handheld barcode scanning terminals, barcode printers, etc.

4. The warehouse management system can help the warehouse managers of enterprises comprehensively control and manage the daily work of inventory materials such as warehousing, warehousing, allocation and inventory, so as to reduce inventory, improve inventory turnover, avoid inventory backlog or shortage, and ensure the smooth progress of production and operation activities. .
