Manufacturing method of ship instrument based on NMEA2000 network


Background technique:

 


Traditional marine tachometers, speedometers, balance meters, water level gauges, water temperature gauges, and oil level gauges are independent of each other. Each instrument requires an independent microcontroller, which has high voltage and cost; each instrument requires an independent The wiring of power lines, ground wires, and backlight control signal lines is complicated; the traditional meters collect analog signals, which have poor anti-interference ability; each meter needs to print dials, which is labor-intensive and not environmentally friendly, so there is an urgent need A new ship gauge that solves the above problems.

 

The purpose of this utility model is to provide a ship instrument based on nmea2000 network, which can simultaneously display the engine running signal and the ship's own positioning signal, highly integrated, significantly reduce the number of ship instrument heads, reduce user cost, and save bridge space.

 

In order to realize the purpose, the utility model discloses a ship instrument based on the nmea2000 network, which includes an nmea2000 interface, a positioning signal receiver, a processing module, a memory, and a display screen. The nmea2000 interface includes a CAN transceiver, and the nmea2000 The engine running signal of the network, the positioning signal receiver receives its own positioning signal, one end of the processing module is connected to the nmea2000 interface, the positioning signal receiver, and the other end is connected to the memory and display screen, and receives the engine running signal and positioning signals, controlling the memory to store the engine running signals and positioning signals, and converting the engine running signals and positioning signals into corresponding image signals and/or digital signals and sending them to the display screen, the display The screen displays the image signal and/or digital signal.

 


Compared with the prior art, on the one hand, the utility model integrates and displays signals such as the engine running signal and the ship's positioning signal on one display screen, which significantly reduces the number of ship instrument gauges, reduces the user's use cost, and saves space on the bridge . On the other hand, the processing module of the utility model converts the collected signals into corresponding image signals and/or digital signals and sends them to the display screen for display, and can provide users with an exquisite graphical interface through the display screen, which is not only efficient in design and environmentally friendly , but also give users a new operating experience.


 
The utility model discloses a ship instrument 100 based on the nmea2000 network, comprising an nmea2000 interface 10, a positioning signal receiver 20, a processing module 30, a memory 50 and a display screen 40, the nmea2000 interface 10 includes a can transceiver, and receives configuration The engine running signal of the nmea2000 network, the positioning signal receiver 20 receives its own positioning signal, one end of the processing module 30 is connected to the nmea2000 interface 10 and the positioning signal receiver 20, and the other end is connected to the memory 50 and the display screen 40, And receive the engine running signal and positioning signal, control the memory 50 to store the engine running signal and positioning signal, and convert the engine running signal and positioning signal into corresponding image signals and/or digital signals and send them to The display screen 40, the display screen 40 displays the image signal and/or digital signal.

 

Wherein, the engine running signal includes speed, water temperature, oil pressure, oil level signal and so on.
