The PLC automated testing device can automatically test the PLC devices.

Description

technical field [0001] The invention relates to the communication field, in particular to a PLC automatic test equipment. Background technique [0002] With the rapid development of science and technology, equipment based on power line communication (PLC) technology has been more and more widely used. By using the power line that transmits current as the communication carrier, the power line communication has great convenience. Where there is a power socket, you can immediately enjoy 4.5-45Mbps high-speed network access without dialing, to browse the web, make calls, and watch online movies, so as to realize the "four-way network" integrating data, voice, video, and electricity. Network into one"! In addition, home appliances such as telephones, TVs, stereos, and refrigerators in the house can be connected by PLC for centralized control, realizing the dream of "smart home". At present, PLC is mainly used as an access technology to provide a broadband network "last mile" so...
