A communication method between groups of ships

Abstract

The invention discloses an intergroup communication method for ships, which includes a data sending end and a data receiving end. The specific steps of the method are as follows: first, the data sending end and the data receiving end complete handshaking; the data sending end automatically detects the communication situation with the data receiving end , when the data sending end and the data receiving end are communicating for the first time, then proceed to the next step; otherwise, skip to step six; the present invention will inform the data receiving end through the data notification table when the data transmission is performed for the first time, and this data sending The content of the data to be sent by the end and the order of the data to be sent; it is convenient for the data receiving end to establish a form in time, fill in the data in order, and complete a basic data transmission; at the same time, if it is not the first data transmission, it will self-check this transmission Whether the order and format of the transmitted data is the same as that of the last transmitted data, if they are the same, continue to transmit, otherwise, a data notification table will be re-established to inform the data receiving end of the specific content of the data sent this time.

Description

technical field [0001] The invention belongs to the field of ship communication, and relates to a ship component communication technology, in particular to a ship intergroup communication method. Background technique [0002] At present, in the process of ship communication, the basic data transmission format of the components in the ship is fixed, that is, the order and content of data transmission are fixed every time the data is transmitted, which leads to the problem that when the ship does not have certain For basic parameters, it still needs to be transmitted in the past according to the specified format and order, which not only affects the data of data transmission, but also occupies data communication resources and affects the overall work efficiency, so it is not necessary; [0003] Moreover, when data is being transmitted, due to the limitations of the ship’s communication network, some data takes up a lot of memory and is troublesome to transmit. There is a lack ...

Problems solved by technology

[0002] At present, in the process of ship communication, the basic data transmission format of the components in the ship is fixed, that is, the order and content of data transmission are fixed every time the data is transmitted, which leads to the problem that when the ship does not have certain For basic parameters, it still needs to be transmitted in the past according to the specified format and order, which not only affects the data of data transmission, but also occupies data communication resources and affects the overall work efficiency, so it is not necessary;

[0003] Moreover, when data is being transmitted, due to the limitations of the ship’s communication network, some data takes up a lot of memory and is troublesome to transmit. There is a lack of an effective data compression format that can compress the data that needs to be transmitted, reduce the size of the data, and speed up the speed of data transmission. ; In order to solve this technical defect, a solution is now provided
