AI Technical Summary
Existing carrier communication and DC pulse communication schemes suffer from problems such as complex circuits, poor anti-interference performance, weak power supply capability, and low communication rate in power supply communication. There is a need for a power supply communication method that has simple circuits, good anti-interference performance, strong power supply capability, and high communication rate.
On a two-wire line, a first voltage signal and a second voltage signal are transmitted in a time-division and direction-division manner. The first voltage signal is used to transmit communication data, and the second voltage signal is used to transmit power. Communication data is transmitted by changing the waveform of the first voltage signal. The first voltage signal and the second voltage signal are voltage signals of different directions and alternate according to a preset time period.
It achieves a power supply and communication method with simple circuit structure, low deployment cost, strong communication reliability, strong power supply capacity, and high communication rate, without the need for additional isolators.
