Communication quality detection method, electronic equipment and system

The invention discloses a communication quality detection method, electronic equipment and a system, a processor in first electronic equipment can transmit a first interference signal through an interference line under the condition that a twisted pair is in an idle state and a time interval from last execution of communication quality detection reaches a preset time interval; the interference is generated on the communication of the twisted pair in an idle state; obtaining first receiving information of a first communication module connected with the output end of the twisted pair, and performing analysis processing of communication quality based on the first receiving information to obtain a communication quality analysis result of the twisted pair; wherein the first receiving information represents information received by the first communication module through the interfered twisted pair. Based on the scheme, the communication quality of the twisted pair in the use process can be detected, and the detectio
