Robot communication system based on electric power carrier wave technology and method

Abstract

The invention relates to a robot communication system based on the electric power carrier wave technology and a method. The system comprises a robot, an electric power wire and an electric power carrier wave transformation device, wherein the robot is used for converting a signal source output signal needing transmission into a standard signal, the electric power wire is used for transmitting the signal in a carrier wave mode, the electric power carrier wave transformation device is connected with the robot and is used for receiving the standard signal sent by the robot, the standard signal is modulated at a high frequency carrier wave signal and is then emitted to the electric power wire for transmission, the electric power carrier wave transformation device is further used for filtering the high frequency modulation signal transmitted through the electric power wire from an electric line, and the frequency signal is demodulated into a voltage signal which is sent to a robot controller for remote control. Through the system and the method, use cost of the cable material and maintenance fee in a traditional cable communication mode are saved, and use reliability of the equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of robot automation, and in particular relates to a robot communication system and method based on power carrier technology. Background technique [0002] Power carrier is a unique communication method of power system. Power carrier technology has begun to be popularized and applied in existing product applications, such as smart home control network, remote meter reading system, remote street lamp monitoring system, and elevators to realize remote calling. The power carrier communication technology refers to the technology of using the existing power line to transmit analog or digital signals at high speed through the carrier mode. Its biggest feature is that it does not need to re-establish the network, as long as there are wires, data transmission can be carried out. [0003] However, in the existing robot workstations, the communication method of the robot master control adopts a special communication ca...
