1 Scope

GB/T 31843 is based on this part of the National Marine Electronics Association 2000 (NMEA2000) standards. NMEA2000 standard Quasi contains minimum requirements for the application of marine electronic equipment on the serial data communication network and the actual ship installation interconnected. Provided pursuant to this section Meter device should have a single signal transmission path capability to share data with a compatible device (including instruction and state).

Data packets passing through a series of data frames, each data packet contains an error and integrity checking, and time frame to ensure that transfer Extension. The actual contents of a data frame of data transfer up to half of the data, this part is suitable for relatively short data packets periodically Transfer, packet transfer instruction as required or requested. Typical data contains discrete parameters (such as latitude and longitude of the location), Global Positioning System Block data (GPS) state value, the autopilot steering commands, limited list of parameters (such as waypoints), and medium-sized (such as the number of electronic charts Database update data). This section does not apply, such as radar, electronic chart, video, data, or other full database or file transfer applications High-bandwidth applications.

This section defines the International Organization for Standardization Open Systems Interconnection model (ISO/OSI) all from the application layer to the physical layer associated layer needs Perform network functional requirements of this part.

This section defines the minimum physical layer data formats, network protocols and devices to interfaces. The International Convention for the Safety of Life at Sea (SO-LAS) The application shall contain redundant devices (such as dual, redundant network interface circuitry) to reduce the impact brought about by the single point of failure.

NMEA2000 standard provides support for redundant equipment, and bus information transfer basic tools and methods. Certain ship-borne equipment safety Fashion design is not within the scope of this section, this section provides some guidance document, see Appendix A.
