Embodiment 1

[0026] Reference figure 2 In this embodiment, it is a heading sending device, which receives a heading angle of RS422 interface from a fiber optic compass, and sends a 1° / revolution auto-aligner signal to the load, one way is 10° / revolution and 360° / revolution The signal constitutes a dual-channel self-aligning machine signal, a 360° / revolution resolver signal.

[0027] The heading sending device in this embodiment includes: an interface unit, which is used to receive the heading angle of the RS422 interface sent by the optical fiber compass, and convert it into the target angle value of the CAN interface to send to the motion control unit through the CAN network. The heading data of different communication protocols of the sensor is converted into a unified format and sent to the internal CAN network through the CAN interface. The unified format includes ID+ data, with valid flags in the ID, and the heading value in the data.

[0028] The heading sending device also includes a p...

Abstract

The invention relates to course sending equipment which comprises an interface unit, a position feedback unit, a motion control unit, a motion execution unit, a gear chain and a sending unit. A course sending method comprises the steps that the interface unit is used for receiving a digital interface course angle sent by a sensor and sending the course angle serving as a target angle to the motion control unit; the position feedback unit detects a current actual angle of the sensing unit and feeds back the actual angle to the motion control unit; the motion control unit acquires a target angle value and an actual angle value, compares the target angle value with the actual angle value for calculation and outputs a control voltage signal to a servo amplifier; the servo amplifier drives an execution motion to drive the gear chain and the sending unit to get close to the target angle until the actual angle value is equal to the target angle value. The course sending equipment disclosed by the invention receives the digital course angle sent by the sensor, can output multiple paths of analog course angles and has the advantages of high driving capacity, high precision, high instantaneity and variety of output formats.

Description

Technical field [0001] The invention relates to ship equipment, in particular to a heading sending equipment in the navigation technology of ship heading. Background technique [0002] Ships need correct and consistent heading information when they are sailing, and the ship's heading information is generated by various sensors (such as magnetic compass, gyro compass, and fiber optic compass). The function of the heading transmitter is to accurately send the heading angle from the sensor to the equipment that needs the information, such as autopilot, radar, electronic chart, heading repeater, etc. On the one hand, the heading transmission device can increase the transmission power and drive more loads; on the other hand, it can isolate the load and the sensor system from each other to improve the reliability of the system. [0003] The performance of the course sending equipment will directly affect the accuracy of the ship's course information. In the prior art, the course sendin...
