NMEA is the abbreviation of National Marine Electronics Association and National Marine Electronics Association of the United States. It is now the unified RTCM standard protocol for GPS navigation equipment. The abbreviation of NMEA is also the Data Transmission Standards Industry Association. Here, it should actually be NMEA 0183. It is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent and related ASCII format. The comma separates the data stream. The length of the data stream varies from 30 to 100 characters. The data stream is usually output at intervals per second. The most commonly used format is "GGA", which includes the positioning time, latitude, longitude, altitude, the number of satellites used for positioning, DOP value, differential state and correction period. Other formats include speed, tracking, Date, etc. NMEA has actually become the most common data output format for all GPS receivers, and it is also used in most software packages that interface with GPS receivers.

The kus NMEA2000 gauge for the traditional marine tachometer, speedometer, balance gauge, water level gauge, water temperature gauge and oil level gauge are independent of each other, and each instrument needs an independent microcontroller, so the voltage and cost are high; Each instrument needs independent power line, ground line and backlight control signal line, and the wiring is complex; The traditional meter collects analog signals with poor anti-interference ability; Each meter head needs to be printed with a dial, which is labor consuming and environmentally friendly. The ship instrument of the nmea2000 network can display the engine running signal and the ship's own positioning signal at the same time, which is highly integrated, significantly reducing the number of ship instrument heads, reducing the user's use cost, and saving the bridge space.

In order to achieve the above goal, the utility model discloses a ship instrument based on the nmea2000 network, which includes the nmea2000 interface, a positioning signal receiver, a processing module, a memory and a display screen. The nmea2000 interface includes a can transceiver, and receives the engine running signal configured with the nmea2000 network. The positioning signal receiver receives its own positioning signal, and one end of the processing module is connected to the nmea2000 interface the other end of the positioning signal receiver is connected with the memory and display screen, and receives the engine running signal and positioning signal, controls the memory to store the engine running signal and positioning signal, and converts the engine running signal and positioning signal into corresponding image signal and/or digital signal and transmits them to the display screen, which displays the image signal and/or digital signal.
