Description

technical field [0001] The invention belongs to the field of communication of underwater robots, and in particular relates to an ROV remote communication system capable of ensuring real-time control and monitoring of underwater robots. Background technique [0002] The ocean is a field that has not yet been developed on a large scale, especially the complex environment of the seabed and the rich and diverse natural resources in the deep sea. Deep sea operation research. Although the ocean development technology is not yet fully mature, underwater robots have achieved extensive scientific research value, engineering experience and economic benefits in deep sea operations. There are two types of underwater robots: one is autonomous, called AUV; the other is remotely controlled, called ROV. ROV is a robot in which the operator remotely controls the robot to work and explore underwater through cables, so the remote communication system is very important. The remote communicat...

Problems solved by technology

The use of optical fiber for communication, although it has the advantages of wide transmission frequency and less susceptible to electromagnetic interference, enhances the reliability of transmission to a certain extent, but its communication part requires light sources, drivers, modulators, optical fibers, repeaters, photoelectric detectors, etc. equipment, which obviously increases the difficulty of research and greatly increases the project development cycle

"Interface Design of RS485 Bus Debugging Equipment", China Science and Technology Information, 2011 (1): 58-60, proposed that RS-485 is a standard interface for bidirectional and balanced transmission, which can suppress common-mode interference, long transmission distance, and easy wiring. Simple and widely used in the industry, but the two-wire RS485 interface can only form a half-duplex network. During the communication process between the surface communication module and the underwater communication module, the bus resources are seriously occupied
