Composition Of Semi-automatic Measuring And Correcting Device For Yacht Magnetic Compass Deviation.

In front of us, we have made some simple introduction to the basic principle of the yacht magnetic compass self-error semi-automatic device, today we mainly introduce the composition of this device and its convenience for navigation operations.
The semi-automatic measuring and correcting device of yacht magnetic compass is fast and effective. It is mainly composed of magnetic field sensor and control box. Next, we will introduce the two major parts respectively.
1. Magnetic field sensor: its main function is to directly induce the synthetic magnetic field of 3 compass, geomagnetic and ship magnetic, and input the simulation information of the synthetic magnetic field to the control box. The sensor is installed on the upper glass plate of the compass.
2. Control box: its main function is to convert the simulated information of the synthesized magnetic field received by a specific device, and the CPU calculates the corresponding coefficient of deviation according to the corresponding mathematical model, as well as display the position of the magnetic bar required to correct the deviation and the number of soft iron sheets placed according to the size of the deviation. After determining the residual deviation, calculate and print the residual deviation on the course at every 5 degrees. After the input of geomagnetic difference, the system can be extended to calculate and display the true course of the ship.
Convenience brought by semi-automatic measurement and calibration device of yacht magnetic compass:
1, greatly simplified the test and calibration steps, just have left, right turn back a week.
2, shorten the test and calibration time, less than half an hour can end the work of test and calibration.
3. Save time and fuel.
4. What is more valuable is that there is no need to set artificial markers for correction of deviation on the shore, or choose a natural marker field, which not only reduces the fatigue of seafarers, but also improves the accuracy of measurement and calibration, and enhances the credibility of the yacht magnetic compass deviation table.
