A driving and communication signal processing method based on the same physical line. The method of the present invention enables the parallel multi-cascade complex power electronic conversion system to realize the transmission and analysis of the drive signal and the communication signal line through a physical line. The system includes a remote control host, multiple drive controllers, and corresponding drive controllers multiple power devices. The remote control host is respectively connected to the local drive controllers 1, 2, ... N through the downlink signal lines 1, 2, ... N, and the signals transmitted by them respectively include drive information 1, communication information 1, ... drive information N, communication information N. Encode the drive information 1, 2, ... N and communication information 1, 2, ... N on the host computer through the high and low levels and the conduction time of the high and low levels, and then decode the local drive controller to convert the The above drive information and communication information are separated. The present invention has the following advantages: 1. Greatly reduces system communication wiring and saves cost; 2. The realization method is simple and effective.
Description
technical field [0001] The invention relates to a signal processing method, in particular to a method for simultaneously transmitting and analyzing a driving signal and a communication signal on a physical signal line. Background technique [0002] With the rapid development of the economy, my country has gradually increased its investment in high-power, high-voltage power transmission, flexible direct current transmission, high-speed rail, etc., making power electronics technology develop in the direction of high-power, high-voltage parallel and cascaded applications. breakthrough. [0003] For multi-parallel and multi-cascade complex power electronic conversion systems, it includes a remote control host and multiple local drive control units. The host needs to send the drive signal to the local drive control unit through the transmission line, and then strengthen the weak signal through the drive control unit and apply it to the power electronic device to complete the high...
