Problems solved by technology

[0003] The gyro compass flow protection device in the prior art has the following disadvantages: 1. It does not have the function of alarm prompt and externally sending out a power failure alarm signal. The motor runs without phase for a long time, and even damages the gyro motor; 2. The maintenance personnel cannot intuitively find the fault point, which prolongs the detection and repair time; 3. No power-off fault alarm signal is sent out to the outside, and emergency shutdown and relocation prompt alarms cannot be performed. Subsequent processing

Embodiment Construction

[0015] Below we will further elaborate on an overcurrent protection and alarm device and method for a gyro compass of the present invention in conjunction with the accompanying drawings and specific examples, in order to understand its structural composition and working principle more clearly, but it cannot be based on this Limit the protection scope of the patent for the present invention.

[0016] Such as figure 1 As shown, an overcurrent protection and alarm device for a gyro compass, the device includes an overcurrent protection unit, an alarm indication unit and an alarm output unit, the overcurrent protection unit includes a fuse 1, and the fuses 1 are respectively connected in series Connected to each input line of the three-phase power supply, the fuse 1 is fused when a certain phase winding of the gyro motor 21 is over-currented, and the phase winding is disconnected to protect the gyro motor 21 accordingly.

[0017] The alarm indication unit includes a first resisto...

Abstract

The invention relates to an overcurrent protection alarm device and method for a gyrocompass. The device comprises an overcurrent protection unit, an alarm indication unit and an alarm output unit. The method comprises the steps that overcurrent protection of gyrocompass three-phase windings is performed through the overcurrent protection alarm device, a light-emitting diode is adopted for indicating the overcurrent winding, and an alarm signal is sent out for follow-up processing. The overcurrent protection alarm device has the advantages of being simple in structure, low in cost, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of ship navigation, in particular to an overcurrent protection alarm device and method for a gyro compass. Background technique [0002] For a long time, the gyro compass, as a navigation instrument that can accurately find the geographic north direction, has been widely used on various ships and has become the main instrument for maritime navigation. The gyro compass uses the fixed axis and precession of the gyroscope to sample the electromagnetic pendulum elevation angle signal in real time, and applies control and compensation current to the gyroscope to finally realize the stable north-pointing function. After the gyro compass is working, the gyro motor must rotate at a high speed so that the gyro can have fixed axis and precession. Therefore, the working state of the gyro motor determines whether the gyro compass can work normally. [0003] The gyro compass flow protection device in the prior art has ...
