Abstract

The invention discloses a DC power line communication device based on RS-485, and the device comprises a control circuit which outputs a control signal; the communication circuit is used for receivingthe control signal output by the control circuit, converting the control signal into a communication signal and outputting the communication signal; the coupling circuit is connected with the communication circuit; and the power supply circuit is connected with the coupling circuit, and the coupling circuit couples the communication signal with the direct current of the power supply circuit and outputs the coupled communication signal through a power line.

Description

technical field [0001] The invention relates to the technical field of industrial network communication, in particular to a DC power line communication device based on RS-485. Background technique [0002] In the field of industrial control, motors are widely used in various automation equipment as an executive component. In the field of small control motors, such as stepper motors and DC brushless motors, they can communicate with peripheral devices through various buses, such as: CANBus , Modbus, Profibus, Profinet, Ethercat, etc. [0003] In the field of motor control, a development trend is that the motor and drive control are integrated together to increase the degree of integration and reduce the size of the entire electronic control system. [0004] The communication bus is a key component of motor control. Existing systems rely on proprietary bus solutions that have worked well for years. However, as new functions are added, complexity increases. The market needs ...
