Abstract

The invention discloses a high-precision digital magnetic compass device, which comprises a power box and an industrial personal computer. The device is characterized in that the device is also provided with a digital azimuth instrument and a digital magnetic compass, the industrial personal computer, the digital azimuth instrument and the digital magnetic compass are connected with the power box respectively, a telescope in the digital azimuth instrument is coaxially connected with an azimuth instrument sensor, the azimuth instrument sensor is in cable connection with a digital signal processing board, the digital signal processing board transmits digital signals to a communication module, and the communication module converts the signals and then inputs the signals into the power box; and a magnetic sensor in the digital magnetic compass is arranged at the upper end of a central shaft of a degausser, a degaussing correction device is arranged at the lower end of the central shaft of the degausser, the central shaft of the degausser can rotate in the degaussing correction device, the magnetic sensor is connected with the communication module, the communication module converts the signals and then inputs the signals into the power box, and the power box converts the received signals and then transmits the signals to the industrial personal computer. The device can perform automatic conversion and control, and has the advantages of simple and convenient operation, safety, reliability, and high cost performance.

Description

technical field [0001] The present invention relates to a modern electronic navigation system, suitable for ship navigation. Background technique [0002] The magnetic compass has been used for nautical pointing in the vast sea for nearly a hundred years. With the development of modern technology today, the traditional magnetic compass is no longer applicable. [0003] When the traditional magnetic compass is used, it must go through error correction and frequent azimuth conversion to get the true azimuth data before it can be used for chart operations. The true orientation measured on the chart must be converted into the magnetic compass orientation in order to be used as the basis for the operation. In addition, there are errors in the magnetic compass itself, and some sea-going ships equipped with magnetic compasses often cause shipwrecks and accidents due to the operator's miscalculation of azimuth. [0004] In view of the disadvantages of magnetic compass, some ships ...
