Scope

This part of GB/T 31843 is formulated according to the National Marine Electronics Association 2000 (NMEA 2000) standard. The NMEA 2000 standard contains minimum application requirements for the interconnection of serial data communication networks with actual ship-mounted marine electronics. Devices designed in accordance with this standard shall have the ability to share data (including instructions and status) with compatible devices in a single signal transmission channel. Data packets are transmitted through a series of data frames, and each data packet includes error and integrity checks to ensure frame delivery and delay. The actual data content of a data frame accounts for at most half of the transmitted data. This part is mainly applicable to the periodic transmission of relatively short data messages, and the messages are transmitted according to requirements or request instructions. Typical data contains discrete parameters (such as latitude and longitude of position), global positioning system (GPS) status values, autopilot steering commands, limited parameter lists (such as waypoints), and medium-sized data block data (such as electronic marine graph database update data). This standard does not apply to high bandwidth applications such as radar, electronic charts, video data or other complete database or file transfer applications. This part defines all relevant layers from the application layer to the physical layer of the International Organization for Standardization Open System Interconnection model (ISO/OSI), which need to implement the network functional requirements of this part. This standard defines the data format, network protocol and minimum physical layer required for the device to interface. The application of the International Convention for the Safety of Life at Sea (SOLAS) should include redundant equipment (eg double network, redundant network interface circuits) to reduce the impact of single point failure. The NMEA 2000 standard provides the basic tools and methods to support redundant devices, buses, and messaging. The installation design of some specific shipboard equipment is not within the scope of this part, but this part provides some guiding documents, see Appendix A.
