technical field

The utility model relates to the fields of communication and ships, in particular to a central service platform device, a mobile terminal and a network system.

Background technique

The Automatic Identification System (AIS) is a kind of ship navigation equipment. Through the use of AIS, the measures to avoid collision between ships can be enhanced, and the functions of radar, ship traffic management system and ship report can be enhanced. AIS adopts the lower four layers of the Open System Interconnect (OSI) seven-layer protocol, and the information processor mainly realizes the low-level software and hardware support for AIS information transmission. The data control procedure of AIS uses High-level Data Link Control (HDLC) technology, HDLC is a bit-oriented protocol, uses bit stuffing to ensure data transparency.

The terminal equipment is connected to the AIS station computer through the AIS pilot port (Pilot Plug). At present, most of them use wired connection, and the port requirements for the terminal equipment are relatively high. If it is inconsistent with the AIS pilot port, it cannot be connected to the AIS station computer. The AIS station machine broadcasts AIS messages through VHF (Very High Frequency, VHF) to transmit ship movement information (such as ship position, speed and heading, etc.). The AIS base station receives the broadcast AIS message and forwards it to the central service platform. The central service platform analyzes the AIS message to obtain the ship movement information.

At present, the pilot can only know the ship's ship movement information through the AIS station computer. If he needs to get the information of other ships and ports, he needs to talk to the staff of the central service platform by telephone or walkie-talkie. This method affects the information. Accuracy and efficiency of acquisition.

The message header includes source address (including IP address) and destination address (including IP address), etc., and the message body includes AIS message. That is, the AIS message is packaged and put into the message body as data. The format of the AIS message is as follows: ! aaccc, x, y, z, c-c, v 3hh, <CR><LF>, where aaccc is an identifier, indicating what information is encapsulated in this sentence, such as identifying the water flow velocity carried in this message. x is the number of sentences required to transmit the message (usually at most 9), y is the sequence number of this sentence in the sentence sequence, and z is the identification mark of continuous information (0-9). c-c is the encapsulation information of this message, such as water speed information. v is the number of bits to fill (0-5). hh is the check byte. "!" means the start character, <CR><LF> means the end character. In the prior art, u is also carried behind the z, indicating the channel (A/B) for receiving the message. Since this embodiment uses the mobile communication network 101 to transmit the message, the channel transmission is no longer used, and the existing VHF transmission is not used. Therefore, this field can be omitted, which saves the message length and reduces the occupation of frequency band resources.

Preferably, the mobile communication network 101 includes a base station 104 (Node B or Evolved Node B) and a core network 105, as shown in FIG. 2 .

Can be 3-5 minutes) send natural information to mobile terminal 103. However, in the prior art, the natural information can only be obtained through the country's information release once every few years. Obviously, the natural information is not as accurate as the natural information obtained in this embodiment.

In this embodiment, the AIS message may also be extended to carry service information. The expanded message looks like: ! x, y, z, aaccc1, c-c, aaccc2, c-c, v 3hh, <CR><LF>, or such as: ! x, y, z, aaccc1, c-c, v 3hh, aaccc2, c-c, v 3hh<CR><LF>. aaccc1 indicates the identification of the original AIS message, aaccc2 indicates the identification of the extended service, and c-c after aaccc2 indicates the data of the extended service. In this way, the service link in the prior art and the link carrying the AIS message can be combined into one link, which reduces the influence of the link connection on the devices at both ends, and reduces the network overhead during channel transmission. Then, the central service platform 102 and the mobile terminal 103 can transmit the message including the AIS message carrying the service information through the mobile communication network 101 .

The mobile terminal 103 uses the received pilot number as an index, and obtains the ship natural information related to the own ship from the received ship natural information. Preferably, when the central service platform 102 sends the ship's natural information, it also sends the corresponding relationship between the ship's natural information and the pilot number. The scheduling plan includes information related to ship scheduling such as departure time, passing location, midway landing location, and return time.
