"Ship News Network" is a public service website for real-time inquiry of ship dynamics. It can provide real-time ship dynamics for shipowners, shippers, freight forwarders, crew members and their families, and bring great convenience to ship safety navigation management, port dispatching plan, logistics, freight forwarders and so on.

Chinese name: ship news network theme: IT field: website area: wide-area nature: overview of ship dynamic public service website, system architecture, data source, products and services, main functions, conclusion, summary website obtains ship dynamic position by means of shore-based AIS, satellite AIS, Inmarsat-C, inmarsat D+, etc., using WebGis technology of public internet, which is intuitive and intuitive. No matter where users are, offices, cafes and airports, as long as they can surf the Internet through computers or mobile phones, they can access the ship news network conveniently and quickly to inquire about the real-time dynamics of ships around the world. System architecture Ship News Network adopts distributed computing and cluster technology. The main system architecture is divided into ship data server, chart server, ship data processing server and client server. The ship data server is used to store the real-time dynamic data of ships received from AIS all over the world. The server automatically converts the binary AIS data stream into readable data through the standard AIS protocol and stores it in the server. When the user requests on the foreground page, the ship data server automatically responds and updates the ship position to the latest. The chart server is used to store and process massive chart data. The server adopts the standard GIS architecture, divides the global charts into 18 levels, and stores the tiled chart data according to certain rules. When there is a user's request, the server automatically transmits the requested chart tiles to the user's computer and downloads them to the user's local cache, so that the next visit will be faster. The ship data processing server is used to process the massive ship dynamic data received every day. The client server is used to store the client's information, customization, authority, arrival reminder, short message sending and receiving, satellite D+ communication, etc. The data source is AIS shore-based AIS, which has the function of receiving and sending AIS messages. Ship News Network deploys AIS equipment receivers in various ports to automatically receive AIS messages sent by ships, and then analyzes the AIS messages through technical means. AIS data has the characteristics of fast speed and timely update, and is especially suitable for ship monitoring in ports and docks. Satellite AIS uses a high-sensitivity AIS receiver installed on a low-orbit satellite. When the satellite passes over the ship, it will receive the AIS signal of the ship and distribute the received AIS data to AIS data centers through the satellite ground station. The ship news network obtains data from the data center through the network, and finally displays it graphically on the chart in the form of ship position. Due to the limitation of communication performance of AIS itself, Inmarsat-C can only receive ship signals with a distance of 30-50 nautical miles. Once the ship is far away from the port, it is difficult to obtain the ship position information through AIS base station. Under this condition, it can only be obtained by satellite. Ship News Network can poll the ship through Station C, and when the ship receives the polling instruction, it will automatically return the current latitude, longitude, course, speed, time and other information. Inmarsat-D+ D+, a maritime communication satellite, is an enhanced version of Inmarsat D station, which has the functions of position report and short message. If you want to get the position of the ship through D+, you need to install a satellite communication device on the ship first, which can automatically send a position report to the ground control center on the shore every hour. In this way, the ship information network can collect the satellite position of the designated ship. Product service dynamic ship news online can locate ships in real time. According to the different speed of the ship, the frequency of ship position update varies from a few seconds to several minutes. Ships outside the coverage area of AIS base station will keep the position when the ship finally receives the signal. Through AIS signal, the ship sends out two kinds of information continuously. One is static information such as ship name, call sign, MMSI, IMO, ship type, captain and width, and the other is static information such as sailing state, draft, latitude and longitude, heading, speed, destination and estimated arrival time. Clipper Clipper is a closed-loop service system independently developed by ShipNews. It takes cargo stowage and chartering as the core, and takes shipowners and shippers as the service objects, and has derived and opened up many third-party logistics service providers, including freight forwarders, shipping agents, ports, finance, insurance, commodity inspection agencies, ship supply companies and so on. It is a fourth-party shipping transaction integration platform that provides OTS(OptionalSolutions) self-service integrated solutions for users. Clippers have changed the traditional way of collecting goods by sea chartering, and established and cultivated a new way to lead users into modern chartering business in the era of big mobile Internet. The birth of clippers subverted the traditional pattern that the maritime chartering market could only find an agent by phone. Using the characteristics of the mobile Internet, online and offline integration, from the initial information of finding a ship to the credit verification of users, to the online signing of contracts, to the supervision of logistics and the use of online payment, draw a perfect o2o closed loop, which is closely connected with shipowners to maximize the user experience. Through the five service systems, clippers can effectively save the logistics cost of shippers, and reduce the waiting and idling rate of ships. (1) The shipping search engine service can self-query the ship position, port plan, capacity, freight rate, pallets and related shipping service providers, expand the market forecast of users, and independently control the logistics cost by 30%. (2) On-line intelligent and accurate ship cargo stowage, negotiation and contract signing services can realize intelligent and accurate ship cargo information matching in real time on the basis of massive ship cargo information on Ship News Network, and can quickly complete intelligent cargo distribution. Realize the real online negotiation between shipowners and shippers, sign contracts, and squeeze ships to perform tracking services. Reduce logistics costs and improve transaction efficiency by 50%. (3) 24-hour call center customer service can alleviate the problems of poor operation and inconvenient time operation of both sides of the ship and cargo, and effectively improve the overall service100%. (4) Establish a marine ecosystem based on industry and integrity, realize the integrity comments of both sides of the ship and cargo and third-party logistics service providers based on online real transactions, and let platform participants establish their own integrity files. Effectively avoid dishonest shipping operations and provide third-party logistics service providers with logistics risks that can effectively reduce 80%. (5) Third-party logistics service providers accurately recommend real transactions as recommendation conditions, and accurately select shipping agents, financial insurance, commodity inspection agencies, shipping supply companies, etc. Continue to supervise and coordinate offline operations for both ship and cargo, thus reducing the burden of a large number of logistics operations. Ship Archives Ship News Network not only provides dynamic information of ships, but also provides ship database from Lloyd's Register of Shipping (now IHS- FairPlay). Lloyd's of the United Kingdom is the IMO number issuing, management and verification department designated by the International Maritime Organization (IMO), and the authority and integrity of its data are unparalleled. Shixun. Com is the exclusive authorized dealer of LRF in Greater China. The complete ship file service includes1.2000 international sailing ships with a gross tonnage of over 300 tons, more than 70000 shipowners and management companies, and more than 6000 shipyards. The data is updated once a week. The data includes more than 200 authoritative files such as detailed technical parameters, construction, P&I association, classification and PSC inspection records, shipowners, operators and transactions of ships and equipment. Satellite AIS AIS is a ship-borne communication equipment, which can continuously transmit the relevant information of the ship, and the data can be received by AIS receiver. Usually, the AIS receiving base station is deployed on land, which can only receive the data of ships within 60 kilometers near the base station, while the satellite AIS is equipped with an AIS receiver on the satellite, which can receive the AIS information of ships all over the world without geographical restrictions. Especially for ship monitoring in the ocean, it provides a revolutionary technical means. At present, the satellite AIS service has commercial value, and more than 20 new satellites will be launched in the next two years. By then, the scope and real-time performance of ship monitoring will be greatly improved, and the history of ship position information service will be completely rewritten! . Electronic Chart Ship News Network They adopted the standard C-map electronic chart produced by Jepperson Company. On this electronic chart, we can intuitively see the situation of all ports and waters in the world, and provide as much information as possible for the safe navigation and safety management of ships. At the same time, the country, port, berth, channel, buoy, anchorage, water depth, navigation obstacles and other information can be seen at a glance on the electronic chart. Mobile phone version of World News. In February and March of 20 12, com launched a variety of mobile phone versions, such as iPhone, ipad, Android and Java, which successfully transferred ship monitoring from computer to mobile Internet. All users only need to download hundreds of K apps, and they can query their ships anytime and anywhere on their mobile phones, which is convenient and fast! Ship Positioning API Ship News Network not only provides ship positioning services, but also develops a data platform (API) to support embedding in other websites and systems in a friendly way, which is convenient for users to realize ship monitoring and management in their own websites and systems. According to the user's purpose and the difficulty of realization, the ship news network provides three data development access methods: (1) complete map/chart+ship position data access; (2) Ship raw data docking; (3) Use the main function of hyperlink docking (1) to query the ship's position, and query the ship through information such as ship name, IMO, MMSI and call sign. (2) Historical trajectory, users can query the ship's navigation trajectory of 1-2 months; (3) Fleet management: users can manage the fleet simply and conveniently through customization and D+ fleet. (4) Arrival reminder: according to the user's settings, send the boat to the user's mobile phone to remind him to set off; (5) Marine meteorology: weather changes, temperature, air pressure, wind direction, wind speed, waves, visibility and other marine meteorological information are superimposed on the chart; (6) Add annotations, and customize to superimpose various personalized annotations on the chart; (7) Ship information, providing detailed information about Lloyd's 6,543,800+2,000 ships; (8) Ship screening, that is, according to the destination, arrival time, ship type, tonnage, country, port and other information, select qualified ships; (9) Ships in the port, count the names and quantities of all ships in the port, and inquire about ship information according to the permission authority; (10) maritime circle; Network national and domestic shipping users and establish a domestic shipping community platform. Conclusion Ship News Network is the earliest website providing ship position monitoring in China. At the initial stage of operation, it has been in a state of high fees and high thresholds, but it has been completely free since August 20 12, which is undoubtedly a good thing for all shipping-related personnel. This move makes maritime trade more transparent, and anyone can find the position of the ship he cares about anywhere, so that the position of the ship is no longer the exclusive privilege of the shipowner.
