Problems solved by technology

[0003] However, the rectification of the communication system requires a lot of manpower and material resources, and the communication system needs to be re-planned and set up
Moreover, the rectification of the grounding system still cannot avoid the interference signals brought by the two communication devices for data transmission in the communication system to the equipotential body, nor can it avoid other near-field interference signals

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication device, method and system. Background technique [0002] In the prior art, when data is transmitted between communication devices in a communication system, the communication transformer in the communication device will be subject to various interferences, thereby generating interference signals to the data signals transmitted between the communication devices. In the prior art, the signal interference phenomenon is reduced by rectifying the equipotential body of the grounding system of the communication equipment. The rectified communication system requires each communication device to have a ground wire connected to the ground busbar, and then the ground busbar is connected to the ground through a thicker ground wire to ensure that the shells of the two communication devices are the same equipotential body , At the same time, the rectified communi...
