Abstract

The invention relates to an umbilical cable communication system for an underwater robot based on a power carrier. A PC terminal is connected to a first Ethernet switch through a network line; the first Ethernet switch is connected to a first power modem through the network line; the first power modem is connected to a second power modem through an alternating-current supply cable; the second power modem is connected to a second Ethernet switch through the network line; and the second Ethernet switch is connected to a data uploading and control instruction sending conversion plate through the network line. According to the invention, systemic data transmission of uploading of multi-channel sensor data, uploading of sonar data and sending of a control instruction is realized on two alternating-current supply cables; the transmission rate is high; and the communication manner is simple and reliable.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to an umbilical cable communication system for underwater robots based on power carrier. Background technique [0002] Underwater robot, also known as unmanned remote control submersible. A kind of extreme operation robot working underwater, which can dive into the water to replace humans to complete certain operations, also known as submersibles. [0003] The underwater movement and operation of the submersible is controlled and monitored by the operator on the surface mothership. Rely on the cable to provide power and exchange information to the body. Repeaters reduce cable interference with body movement. [0004] Chinese patent CN200820011902 discloses a remote control underwater robot repeater control device based on twisted pair, but it uses twisted pair to transmit communication, and the communication efficiency is low. The underwater robot in the prior art needs to use co...
