Inter-group communication method for ship

Abstract

The invention discloses an inter-group communication method for ships, which comprises a data sending end and a data receiving end, and comprises the following specific steps: firstly, the data sending end and the data receiving end complete handshake; the data sending end automatically detects the communication condition with the data receiving end, and when the data sending end and the data receiving end are in primary communication, the next step is executed; otherwise, skipping to the step 6. According to the invention, when data transmission is carried out for the first time, the data receiving end, the data content to be sent by the data sending end and the sending data sequence are notified through the data notification table; a data receiving end can conveniently establish a tablein time and fill data according to a sequence to finish the transmission of basic data; meanwhile, if the data transmission is not performed for the first time, whether the sequence and format of thedata transmitted this time are the same as those of the data transmitted last time or not can be self-checked, if yes, transmission is continued, and otherwise, a data notification table is reestablished to inform a data receiving end of the specific content of the data transmitted 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
