Marine gauge panel or boat gauge panel include the speedometer , tachometer , fuel level gauge , oil pressure gauge , voltmeter , water temp gauge , rudder angle indicator , trim gauge and so on. Customers can choose which gauges are needed. Also can customized.

The instrument on the ship is used to provide the required ship operation parameter information for the pilot. The ship's instrument panel is composed of various instruments and indicators, especially the pilot's warning light alarm. According to different working principles of ship instruments, they can be roughly divided into three generations.

The traditional speedometer is mechanical. A typical mechanical odometer is connected to a flexible shaft. There is a steel wire cable in the flexible shaft. The other end of the flexible shaft is connected to a gear of the transmission. The gear rotation drives the steel wire cable to rotate. The steel wire cable drives a magnet in the cover ring of the odometer to rotate. The cover ring is connected with the pointer and the pointer is set to zero through a hairspring. The speed of the magnet rotation causes the change of the size of the magnetic line of force, The balance is broken and the pointer is driven accordingly.

A common way is to obtain signals from the speed sensor on the transmission and deflect the pointer or display numbers through the change of pulse frequency . The buttons on the instrument panel are used to switch the display function of the instrument panel . For example , most of the buttons display the total mileage, which can be switched to the range mileage , or to the subtotal mileage and average fuel consumption. Depending on the model , the switching content is different. Long press should clear the subtotal mileage.

In order to meet the needs of the development of marine automatic power station towards the direction of bus intelligent control, in view of the defects of non digital marine synchronous instruments, the embedded microcontroller is used to carry out intelligent control of the instruments, and the electromagnetic compatibility (EMC) design of the microcontroller is carried out according to the working environment of the marine engine room, so as to realize the field bus interface design of bus embedded control , so that the synchronous instrument becomes a bus intelligent synchronous detection , indication.
