Abstract

The invention provides a remote and near-distance communication method and a communication system of a UUV (unmanned UUV), which are characterized in that through integrating the double modes of Beidou three-generation satellite communication and Bluetooth communication, when the UUV floats to the water surface, position information is acquired by utilizing a satellite position indicating device and is remotely transmitted to a shore station through a Beidou satellite, the shore station can issue a control instruction through the satellite, and the satellite position indicating device forwards the control instruction to a UUV navigation control center through an RS422 interface, so that remote state monitoring and navigation control are realized. In a short-distance range, the shore station directly communicates with the satellite position indicating device through Bluetooth to complete parameter configuration, instruction issuing and state reading. The method solves the problem that the traditional underwater acoustic communication is limited by distance, realizes the controllable communication of the UUV in the full time domain and the full space domain, improves the reliability, the safety and the operation and maintenance convenience of the UUV operation, and is suitable for the fields of ocean exploration, resource investigation, military application and the like.
