Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] The invention relates to an autopilot based on CAN (Controller Area Network, local area control network) bus communication and control. By designing a reliable and reasonable networking method, not only the automatic driving function of the autopilot is realized, but also the autopilot is completed. Safe and effective data exchange between internal network and external network, with rich expansion functions.

[0028] figure 1 is a schematic diagram of an autopilot according to an embodiment of the present invention. Such as figure 1 As shown, the autopilot includes: an operation unit 102, connected to the first local area control network 106, for receiving specified heading information and control information for the control algorithm, and passing the specified heading information through the first local area control netw...

Abstract

This invention provides an autopilot, including: an operation unit connected to a first LAN control network and used for receiving the specified course information and controlling the control information of algorithm and sending the specified information and control information to a first main control unit through the first LAN control network; an interface processing unit connected to the first LAN control network and used for sending the information from an external device related to the current course through the first LAN control network; and a first main control unit connected to the first LAN control network and used for receiving the specified course information, the control information and the information related to the current course through the first LAN control network, and used for computing a rudder order through controlling the algorithm based on the specified course information, the control information and the information related to the current course, and used for controlling the steering apparatus based on the rudder order.

Description

technical field [0001] The invention relates to an automatic rudder on a ship, in particular to an automatic steering instrument. Background technique [0002] About the autopilot: [0003] The autopilot is used to realize the automatic driving of the ship. It is based on the follow-up rudder, using gyro compass or magnetic compass, GPS and other equipment, through real-time acquisition of the yaw signal between the actual course and the set course, the speed of the ship, and the environment such as sea conditions, wind, waves, currents, etc. Information, automatically run the track control algorithm, calculate and give the rudder order to control the ship to the specified course / track, and finally realize the automatic driving function. The interior of the autopilot involves data exchange between multiple functional units and various ship sensors. At the same time, it needs to be connected to the ship equipment network to exchange data with other ship equipment. [0004]...
