1 Scope

This part of GB/T 31843 stipulates that between shipboard navigation and radio communication equipment, as well as these systems and other

Requirements and test methods for high-speed communication interfaces between ship systems in which aviation and radio equipment communicate. This section is applying existing international standards

On the basis of standard, the data transmission framework between shipboard Ethernet devices is proposed.

The Ethernet specified in this section is based on a bus network, and the receiver can receive messages from the transmitter when the following conditions are met.

--- This section includes provisions for multicast distribution of messages formatted according to the requirements of IEC 61162-1, such as location correction and

Other measurement methods; also includes provisions for the transmission of general data packets (binary files), such as transmission between radar and navigation data recorder

Input; also includes provisions for multicast distribution of messages formatted according to IEC 61162-3 requirements, such as position correction and other

measuring.

--- This part is limited to the protocol used by devices (network nodes) connected to a simplex Ethernet network.

It consists of two devices and control lines (network infrastructure).

--- The requirements presented in this section are limited to device interfaces. The provisions of the agreement are to ensure that the equipment implementing this part is transmitted between

Interoperability requirements for IEC 61162-1 designated sentences, IEC 61162-3PGN information, and general binary image data are also available

Ensure certain security of the device itself.

--- If the interface of the network infrastructure meets the requirements of other network functions (ONF, see 4.6), this part allows the equipment to adopt this part

The network infrastructure is shared by agreements other than the prescribed agreements.

--- This section includes provisions for network traffic filtering in order to limit the traffic of each device to a manageable level.

--- In addition to the requirements that can be summarized from the requirements of a single device, this section does not include any system requirements. Related standards

IEC 61162-460 further elaborated the system requirements.
