Description

technical field [0001] The invention relates to the technical field of medium-voltage multiple-input multiple-output power line carrier communication, in particular to a medium-voltage MIMO-PLC access terminal state monitoring device. Background technique [0002] Multiple-input multiple-output power line carrier (MIMO-PLC) communication technology is a communication access network technology that combines MIMO-OFDM and PLC technology to achieve higher efficiency and reliability. MIMO-PLC power line communication technology can solve the last mile communication problem in the Internet of Things. However, with the explosive growth of ubiquitous power Internet of Things terminals, the current medium-voltage MIMO-PLC technology is difficult to cope with the future communication scenarios of massive terminal access. At the same time, the security of power line transmission is facing increasingly severe tests. In the context of explosive growth in the number of system device con...
