Abstract

The invention relates to a power line signal transmission method and device and transmission electric equipment. The method comprises the following steps: receiving a communication signal and power supply voltage; coupling the power supply voltage and the communication signal so as to obtain a carrier signal; and transmitting the carrier signal to the controlled side through the power line. The power supply voltage and the communication signal of the control side are coupled to obtain the carrier signal and then the carrier signal is transmitted to the controlled side through the power line carrier so that power line carrier transmission can be realized, the communication line and the power line can be integrated, the number of connection lines between the control side and the controlled side can be reduced, the connection complexity can be reduced and the connection convenience between the control side and the controlled side can be improved.

Description

technical field [0001] The present application relates to the technical field of power communication, in particular to a power line signal transmission method, device and transmission electrical equipment. Background technique [0002] With the development of power communication technology, AC permanent magnet synchronous motors are often controlled by servo drives in automation equipment such as industrial robots and CNC machining centers. Servo drives are an important part of modern motion control. The connection between servo drives has always been divided into communication lines. And power lines, power lines can be classified according to the objects that provide energy support: strong electric power lines and low-voltage or low-power consumption power lines, communication lines can also be divided into multiple types according to different communication methods. In different application environments, the types and quantities of communication lines and power lines requi...
