how to hook a fuel level gauge to nmea 2000 network
The purpose of the new model is to provide a ship instrument(incloding fuel level gauge,speedometer and so on) based on NMEA2000 network, which can display the engine running signal and the ship's own positioning signal at the same time. It is highly integrated, which can significantly reduce the number of ship instrument headers, reduce the user's use cost and save the bridge space.
In order to achieve the above purpose, the utility model discloses a ship instrument based on NMEA2000 network, which comprises NMEA2000 interface, positioning signal receiver, processing module, memory and display screen. The NMEA2000 interface includes can transceiver and receives the engine running signal configured with NMEA2000 network. The positioning signal receiver receives its own positioning signal, and one end of the processing module is connected with the NMEA2000 interface The other end of the positioning signal receiver is connected with the memory and display screen, receives the engine running signal and positioning signal, controls the memory to store the engine running signal and positioning signal, converts the engine running signal and positioning signal into corresponding image signal and / or digital signal and transmits them to the display screen, and the display screen displays the image signal and / or digital signal.
Compared with the prior art, on the one hand, the utility model integrates and displays the engine running signal, ship positioning signal and other signals on a display screen, which significantly reduces the number of ship instrument headers, reduces the user's use cost and saves the bridge space. On the other hand, the processing module of the utility model converts the collected signals into corresponding image signals and / or digital signals and transmits them to the display screen for display. It can provide users with a beautiful graphical interface through the display screen, which is not only efficient and environmentally friendly, but also gives users a new operation experience. The input of NMEA2000 interface 10 is a digital signal. In order to facilitate the user's use, the ship instrument 100 is also provided with a conversion key. The user inputs the conversion command, and the processing module 30 converts the signal transmitted to the display screen 40 into corresponding units, such as knots, km / h or mph, according to the conversion command, so as to be applicable to all customer groups in different countries or regions.
