And 102, carrying out multicast group distribution according to data requirements to obtain a multicast group.
Because the data required by different intelligent application terminals may be overlapped, multicast group allocation can be performed according to the data requirements of different intelligent application terminals to obtain one or more multicast groups, and one multicast group corresponds to at least two intelligent application terminals.

For example, the target data corresponding to the intelligent application terminal 1 includes the host rotation speed, and the target data corresponding to the intelligent application terminal 2 also includes the host rotation speed, so that the intelligent application terminal 1 and the intelligent application terminal 2 are both divided into members of the same multicast group.

It should be noted that, in the above embodiment 1 and embodiment 2, only the multicast group is allocated to the intelligent application terminal, and in addition, the intelligent application terminal may exit from the multicast group, for example, when the intelligent application terminal has a program failure, even if data is obtained, it does not have meaning, the intelligent application terminal may exit from the multicast group, so as to further save the overhead of data transmission; or, the intelligent application terminal changes another multicast group, for example, the first application type of the intelligent application terminal is changed into the second application type through program reinstallation or upgrade, the data requirement is also changed, and then the member of the original multicast group needs to remove the intelligent application terminal and redistribute to another multicast group.

The application types of the intelligent application terminal are limited, so that data requirements are determined according to different application types, the intelligent application of the intelligent ship is highlighted in ship body, navigation, cabin, energy efficiency and ship safety, and the intelligent direction of the ship is pointed out.
Alternatively, on the basis of the embodiment 4 shown in fig. 4, in a preferred embodiment of the present application,

For example, the target data corresponding to the intelligent application terminal 1 includes the host rotation speed, and the target data corresponding to the intelligent application terminal 2 also includes the host rotation speed, so that the intelligent application terminal 1 and the intelligent application terminal 2 are both divided into members of the same multicast group. After the target data of each intelligent application terminal is determined by the data requirements, the target data is used for dividing the intelligent application terminals into one or more members of the multicast group, and the construction of data transmission in a multicast mode is realized.
Alternatively, on the basis of the embodiment 3 shown in fig. 3, in a preferred embodiment of the present application,

the data distribution module 303 is further configured to send the multicast data to the corresponding intelligent application terminal in a multicast manner.
By adopting the technical scheme, when ship data of an intelligent ship are acquired through various ship sensors, due to the fact that a multicast mode is adopted, the data distribution module 303 processes the ship data by using a preset multicast protocol to obtain multiple groups of multicast data, each group of multicast data corresponds to one multicast group, the intelligent application terminals corresponding to the multicast data can be determined under the condition that the multicast group corresponding to the multicast data is known, and the intelligent application terminals corresponding to the multicast data are determined in members of the multicast group, and the multicast data are sent to the corresponding intelligent application terminals through the multicast mode. The ship data transmission in a multicast mode is realized, data do not need to be transmitted independently for each intelligent application terminal, and the data transmission pressure is reduced.
