Background

With the increasing frequency and urgency of ocean exploration, underwater robots are widely used as an important tool.

Because the application environment of the underwater robot is complex and changeable, it becomes very important that the underwater robot and the mother ship keep communication. In particular, auv (autonomous Underwater vehicle) can communicate with a mother ship only using wireless communication equipment since it has no cable connection with the mother ship. The wireless communication which can be used for the underwater robot at present mainly comprises the following types:

the low-frequency radio communication generally uses a radio data transmission station as communication equipment, and is characterized by simple use, capability of receiving and transmitting data through a serial port and communication distance up to dozens of kilometers; the defects are that the communication speed is low, generally can reach dozens of kbps, the communication distance is greatly influenced by the environments such as terrain and the like, and the communication distance is greatly reduced when the communication distance is shielded; generally, only equipment cost is required to be invested, and additional payment is not required for communication.

The high-frequency radio communication can use a wireless network bridge as wireless communication equipment, data is transmitted and received through an Ethernet port, the communication rate can reach 11Mbps and 54Mbps, the communication distance can generally reach 3-5 kilometers, and generally only the line-of-sight communication can be performed due to higher frequency and lower signal diffraction capability; generally, only equipment cost is required to be invested, and additional payment is not required for communication.

Satellite communication is more typical of iridium and Beidou communication. Satellite communication is generally not influenced by terrain, communication distance is determined by satellite signal coverage, the iridium satellite can achieve global coverage, and the Beidou can cover peripheral areas of China at present. The satellite communication rate is low, the communication equipment cost and the traffic cost generated by communication need to be paid, and the communication cost is high.

2G/3G mobile communication, the communication speed can reach dozens of kbps to several Mbps, the communication can be carried out only in the place with 2G/3G mobile signals, the normal communication can be carried out on most of land and offshore, but no signals are generally available in the open sea. Besides the communication equipment cost, the traffic cost generated by communication needs to be paid, but the comprehensive cost is lower than that of satellite communication.

The underwater acoustic communication can be carried out underwater. The communication distance is related to the signal frequency, and the like, and the communication rate is generally low.

The communication means can be used independently only for keeping communication within a period of time when the underwater robot hits, various wireless communication devices are managed and dispatched comprehensively, and it is important to keep the underwater robot continuously connected with a mother ship during the mission execution.
