SLAVE SUITABLE FOR ENERGY MANAGEMENT SYSTEMS AND ENERGY MANAGEMENT SYSTEM

摘要

The slave is used in an energy management system for collecting meter-reading data from an energy meter for measuring an amount of electric energy supplied from a power source to a predetermined place through a distribution line. The slave includes: a first interface unit configured to communicate with an upper device; a second interface unit configured to communicate with an electric appliance installed in the predetermined place; and a third interface unit configured to perform first wireless communication using an electric wave with a communication terminal. One of the first interface unit and the second interface unit is a wired communication unit configured to perform power line communication using the distribution line, and the other of the first interface unit and the second interface unit is a wireless communication unit configured to perform second wireless communication using an electric wave.
