Abstract

The present invention provides a method of using power line communication, adding a transmission line for signal transmission in the power supply line, including the following steps: the sender generates information to be sent; directly modulates the AC signal for power supply according to the information to be sent to The signal voltage in the transmission line; the receiver obtains information according to the variation of the signal voltage in the transmission line. By adopting the technical scheme of the present invention, data communication through AC signals can be realized only by adding one transmission line, and the transmission line and the live wire can be arranged together when wiring, so as to realize safe and reliable long-distance data communication in a relatively simple way, thereby greatly reducing the hardware cost.

Description

technical field [0001] The invention relates to the field of power line transmission, in particular to a method for using power line communication. Background technique [0002] With the development of information technology, the application of intelligence and remote communication in various occasions is gradually increasing, but at present, information communication generally adopts wired or wireless methods. The use of wireless transmission will generate electromagnetic radiation, which will cause damage to the human body, and due to the characteristics of wireless signals, it will cause signal attenuation when penetrating obstacles, which will cause problems such as information loss in signal transmission. [0003] In the way of wired transmission, such as UART, CAN, SPI, DALI, etc., in addition to the two power lines (VCC and GND), it is necessary to arrange another set of communication lines. In order to ensure the safety of electricity use, there must be a certain di...
