Abstract

The invention provides an unmanned ship system based on RTK technology. The system comprises an external reference station and a driving ship. The reference station is used for sending RTK differencedata. The driving ship is provided with a GNSS receiver used for collecting locating information of the driving ship; a radio module used for carrying out precision calculation according to the locating information and the RTK difference data sent by the reference station; a data acquisition module used for collecting driving data of the driving ship; a communication module used for receiving a remote control command of an external remote controller; a data fusion module used for fusing the driving data, the locating information and the RTK difference data obtained after precision calculationto obtain fused data; a ship master control unit used for receiving the fused data sent by the data fusion module and the remote control command of the external remote controller and generating a control signal; and a ship execution unit connected with the ship master control unit and used for responding to the control signal of the ship master control unit and controlling a sounding boat to carryout corresponding operation. The system greatly improves intelligence level and stability of the unmanned ship.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to an unmanned ship system based on RTK technology. Background technique [0002] With the development of social technology, unmanned driving technology has attracted the attention of the society, especially with the application and development of unmanned aerial vehicle technology, unmanned ship platforms (referred to as unmanned ships) have also emerged and developed along with the trend. Special missions such as maritime rescue, maritime survey, and dangerous goods monitoring provide a carrying platform and have great application prospects. Unmanned ships are a complex system that integrates ship design, intelligent control, artificial intelligence, information processing, detection and Its research content involves many aspects: automatic driving, autonomous obstacle avoidance, planning and navigation, pattern recognition, etc. Since unmanned ships are required to be able t...
