custom boat gauge panels instruments

• 2022-09-07

Our company has custom boat gauge panels. Generally speaking, the current marine boat gauge panels instruments are all electronic, so the working principle of marine frequency meters, power meters, power factor meters and so on is to sample voltage or current, convert voltage signals or current signals into digital signals, and then send them to the CPU of the custom boat gauge panels instruments, which is generally a single chip microcomputer. Nowadays, arm and DSP chips are also used. The single-chip computer calculates and processes the required data directly , and then displays it . For example, the frequency meter displays the frequency of the obtained voltage , the power meter displays the output power of the generator , the power factor meter displays the power factor of the load, and so on. To put it simply, it uses digital processing technology.

The early boat gauge panels instruments of this kind were electromagnetic. They all used the characteristics of alternating current to convert them into current signals and magnetic fields. Through the synthesis of several magnetic fields, the pointer was deflected and the required data was obtained.

As for wiring, there is a schematic diagram on the back of the custom boat gauge panels instrument. Please connect according to the schematic diagram . There are instructions. Usually, regular manufacturers have their own websites . Product instructions are also generally put on the Internet for users to download . At least , our company has been doing this for nearly 5 years.

In order to meet the needs of the development of boat automation power station in the direction of bus intelligent control , aiming at the defects of non Digital Marine synchronous custom boat gauge panels instruments, embedded microcontrollers are used to intelligently control the instruments, and the microcontrollers are designed for electromagnetic compatibility (EMC) according to the working environment of the ship engine room , so as to realize the field bus interface design of bus embedded control , and make the synchronous instruments become bus intelligent synchronous detection, indication. The control instrument, upper computer and other intelligent instruments are connected to the bus network through can interface The test shows that the intelligent instrument system based on Fieldbus has strong anti-interference and reliable performance. Compared with traditional instruments , it has a great improvement in measurement speed , accuracy , automation and cost performance.
