Abstract
The utility model relates to a ship compass which comprises a gyrocompass, an inclination angle measurement device and an attitude interface circuit, wherein the gyrocompass and the output of the inclination angle measurement device are connected with the attitude interface circuit. The output is an output of course attitude signals. Therefore, measurement of the trimming angles and the heel angles of ships can be realized at a low cost. Meanwhile, the ship compass can provide course information with high accuracy. The ship compass is suitable for a ship guide system with the requirements for measuring the trimming angles and the heel angles of ships.
Description
Technical field
The utility model relates to a kind of mariner's compass, the especially a kind of course of boats and ships and the mariner's compass of measurement of dip angle.
Background technology
Mariner's compass can only be exported course information at present, and the pitch angle of boats and ships generally is to measure, show by mechanical pendulum hammer inclinator.Adopt the precision of the method lower, and can't be with the branch display, show that at needs the place at inclination angle can only refill an inclinator.Therefore to adorn many inclinators on the common ship.And generally can only adopt platform compass in the place that measurement of dip angle is had relatively high expectations.The general gyroscope that adopts two orthogonal installations of platform compass, the measurement in a responsible course, another is responsible for the measurement of attitude.Because accuracy requirements such as gyrostatic processing and assembling are very high, so platform compass cost height, can not be used widely.
Summary of the invention
Its purpose of the utility model just is a kind of mariner's compass is provided, and has realized boats and ships measurement of dip angle cheaply, can provide high-precision course information simultaneously.
The technical scheme that realizes above-mentioned purpose and get comprises gyrocompass, also comprises measurement of dip angle and gesture interface circuit, and described gyrocompass and measurement of dip angle output connect the gesture interface circuit, and it is output as course attitude signal output.
Compared with prior art the utlity model has following advantage.
Owing to adopted the structural design of gyrocompass and obliquity sensor combination, thereby realized boats and ships measurement of dip angle cheaply, can provide high-precision course information simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure principle schematic;
Fig. 2 is this device measurement of dip angle electricity principle schematic.
Embodiment
Embodiment comprises gyrocompass, as shown in Figure 1, also comprises measurement of dip angle and gesture interface circuit, and described gyrocompass and measurement of dip angle output connect the gesture interface circuit, and it is output as course attitude signal output.The gesture interface circuit is responsible for receiving the course information of gyrocompass output and the attitude information of measurement of dip angle circuit output, and its packing is sent.
Described measurement of dip angle comprises acceleration transducer, pre-amplification circuit, A/D change-over circuit and Single Chip Microcomputer (SCM) system, as shown in Figure 2, acceleration transducer is gathered acceleration information, through output voltage values after the internal conversion, magnitude of voltage is divided into two-way, one is the acceleration on the measured X direction of principal axis, another is the acceleration of measuring on the Y direction, the two-way voltage signal is through low-pass filtering, voltage after output is amplified after the operational amplifier processing and amplifying is given the A/D modular converter, the A/D modular converter is exported 12 bit digital quantity and is handled to single-chip microcomputer, the angle of inclination of the last serial port output of single-chip microcomputer digital quantity.
By gyrocompass with by the obliquity sensor combination that accelerometer is formed, realize the boats and ships measurement of dip angle.
Gyrocompass has the function of looking for north automatically, and its energy autostable is in meridian ellipse.Therefore, the orientation that it can the relative north orientation of measurement target or on movable body, indicate the course.
The whole hardware design principle of measurement of dip angle as shown in Figure 2, it partly is made up of acceleration transducer, pre-amplification circuit, A/D change-over circuit and Single Chip Microcomputer (SCM) system etc.Acceleration transducer is gathered acceleration information, and through output voltage values after the internal conversion, magnitude of voltage is divided into two-way, and one is the acceleration on the measured X direction of principal axis; Another is the acceleration of measuring on the Y direction.Voltage after output is amplified after two-way voltage signal process low-pass filtering, the operational amplifier processing and amplifying is given the A/D modular converter, and the A/D modular converter is exported 12 bit digital quantity and handled to single-chip microcomputer, the angle of inclination of the last serial port output of single-chip microcomputer digital quantity.
An interface card is arranged in system, receive course, inclination information simultaneously, and will send with the digital quantity form after all information package.Can show by repeater at remote port as required, and can realize that multichannel shows.
