Magnetoelectric combined course indicator and combined course indicating method

Abstract

The invention provides a magneto-electric combined type heading indicator and a combined type heading indication method. The heading indicator consists of a flux gate compass, an electromagnetic controlled gyrocompass and a navigational computer, wherein, an output interface of the flux gate compass is connected to an input interface of the navigational computer, the output interface of the electromagnetic controlled gyrocompass is connected to the input interface of the navigational computer, the output interface of the navigational computer is connected to the input interface of the flux gate compass, the output interface of the navigational computer is connected to the input interface of the electromagnetic controlled gyrocompass, the output interface of the navigational computer is connected to an external heading display system. The invention utilizes electronic circuits and computer hardware and software technologies to organically combine the flux gate heading instruction technology with the gyro heading instruction technology, which can overcome the shortcomings that the flux gate technology cannot instruct true north of a geographic coordinate system and is liable to be interfered by the surrounding magnetic field environment, and simultaneously solve the problems that the starting time of a gyro heading indication system is long, and the heading indication accuracy is reduced over time.

Description

(1) Technical field [0001] The invention relates to a vehicle heading indicating device, in particular to a device which comprehensively utilizes the information of the earth's magnetic field and the information of the earth's rotation to indicate the heading. The present invention also relates to a heading indicating method based on the heading indicating device. (2) Background technology [0002] The compass that uses the information of the earth's magnetic field to indicate the course is one of the four great inventions in ancient China. Its main method is to suspend a permanent magnetic material in the liquid, and use the principle of repulsion of the same sex and attraction of the opposite sex to roughly indicate the direction of north and south. method. The basic principle of the "magnetic compass" technology widely used in modern navigation is also the same. At present, the magnetic compass used on the ship is large in size and heavy in weight, and needs to occupy a...

Problems solved by technology

[0011] The purpose of the present invention is to provide an organic combination of the fluxgate heading indication technology and the gyro heading indication technology, which can overcome the shortcomings of the fluxgate technology being unable to indicate the true north of the geographic coordinate system and being easily disturbed by the surrounding magnetic field environment. It is also a magnetoelectric composite heading indicator that can solve the problem that the gyro heading indicator system takes a long time to start and the accuracy of the heading indicator decreases with time.
