Abstract

The invention belongs to the technical field of power carrier communication and provides a variable-speed motor networking system based on power carrier communication technology. The variable-speed motor networking system based on power carrier communication technology programs, controls, and detects multiple variable-speed motor systems by a same power line such that the multiple variable-speed motor systems communicate with a master control device through the same power line when a communication line is not required to be laid. The variable-speed motor networking system is simple and fast in communication mode, low in cost, and free of radiofrequency radiation and the master control device may easily program, control, and monitor a motor controller in the variable-speed motor system. A problem of a complex communication mode and high cost of a wired network and a wireless network in the prior art is solved. A problem of radiofrequency radiation and increased standby power consumption of the motor controller is prevented when a wireless network is used.

Description

technical field [0001] The invention belongs to the technical field of power carrier communication, and in particular relates to a variable-speed motor networking system based on power carrier communication technology. Background technique [0002] At present, the motor as a power output device is widely used in various equipment that requires power drive, such as variable speed motors (such as permanent magnet synchronous motors, brushless DC motors, stepping motors, etc.) are controlled by their corresponding motor controllers. The speed control is used in equipment (such as air conditioners) that need to adjust the operating speed. The variable speed motor and the motor controller form a variable speed motor system. Generally speaking, a large number of variable-speed motors are required for power supply in large-scale systems, which is equivalent to the need to use multiple variable-speed motor systems, so the operation control of multiple variable-speed motor systems is...
