Gyrocompass signal simulating generator

Abstract

The invention relates to a gyrocompass signal simulating generator, and solves the technical problem that during phase zero crossing of a signal of a hand-operated self-synchronous motor, an output signal waveform is not in proportion to a reference fundamental wave signal but in proportion to a frequency signal. A computer control unit, a lower computer master control unit and four channels of digital-to-analogue conversion units connected with the lower computer master control unit are adopted, and each channel of digital-to-analogue conversion unit is successively connected with a signal amplifying circuit and an output interface; each output interface has a Y-shaped structure; the computer control unit transmits user input parameters to the lower computer master control unit; the digital-to-analogue conversion units convert digital signals transmitted by a master control unit into analogue signals; and the output voltage Vpp of the signal amplifying circuits is equal to 160 V + / - 10%, the carrier signal frequency is 100 HZ+ / - 10%, an envelope signal frequency range is adjustable in 1Hz+ / - 10%-30 HZ+ / - 10%, the problem is solved well, and thus, the gyrocompass signal simulatinggenerator can be used in production and repairing processes of ships and warships.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a gyrocompass signal simulation generator. Background technique [0002] At present, our country is a big ocean country and a big shipbuilding country. It is striding forward to a powerful ocean country and a powerful shipbuilding country. The influence of magnetism is small, and it can provide a more accurate heading reference, and it can also serve as a reference for the missiles and artillery on the ship. In the process of ship production and maintenance, a gyrocompass signal simulation generator is needed to help debug the equipment on the ship that needs to receive gyrocompass signals, which can greatly improve work efficiency. At the same time, the single-chip microcomputer technology is developing rapidly, with higher and higher precision and faster speed. It has been applied in various fields. Intelligent equipment is also the direction of research nowadays. Combined wit...

Problems solved by technology

The hand-operated self-aligning machine works in a complex environment for a long time. When the three-phase signal output by this method crosses zero, the output signal waveform is no longer proportional to the reference fundamental wave signal, but a signal frequency signal. Therefore, in At this working point, when the synchro that simulates the heading does not move, the heading angle of the signal receiving device increases or decreases continuously, and the synchro is no longer suitable as a gyrocompass signal simulation generator

At the same time, the equipment is low in intelligence, and the manual type cannot accurately control the angular velocity and rotation angle, which is prone to large errors and is inconvenient

Single-chip microcomputer and DSC module are the core, the method of realizing signal output is only three-way signal output, lack of fundamental wave signal, in addition, the output signal voltage of this method has not reached Vpp=160V
