Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a two-wire power supply carrier communication device and method. Background technique [0002] There are a variety of communication methods in the current electronic computer technology field, specifically divided into wireless communication and wired communication; wireless communication such as Bluetooth communication, WIFI communication, 2G / 3G / 4G / 5G communication, and wired communication such as RS485 communication, RS232 communication , TTL communication, CAN communication and so on. Comparing the two communication methods, we will find that wireless communication has problems such as high circuit cost, high power consumption, radiation, and multiple wireless communications exist in the same space, which easily cause mutual interference; while wired communication belongs to proprietary system communication or The communication method in a fixed system, and fur...

Problems solved by technology

Comparing the two communication methods, we will find that wireless communication has problems such as high circuit cost, high power consumption, radiation, and multiple wireless communications exist in the same space, which easily cause mutual interference; while wired communication belongs to proprietary system communication or The communication method in a fixed system, and further comparison of several wired communication methods, we will find that they have their own advantages and disadvantages, some cannot carry out high-speed communication transmission, some cannot carry out long-distance transmission, and some will occupy a lot of hardware resources. When many devices need to transmit data at high speed in the same network, the above wired communication methods are not fully capable
