SLAVE SUITABLE FOR ENERGY MANAGEMENT SYSTEMS AND ENERGY MANAGEMENT SYSTEM
First Claim
1. A slave suitable for energy management systems for collecting, from an energy meter for measuring an amount of electric energy supplied from a power source to a predetermined place through a distribution line, meter-reading data containing the amount of electric energy,the slave comprising:
- 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;
a third interface unit configured to perform first wireless communication using an electric wave with a communication terminal; and
a controller having;
a function of obtaining the meter-reading data from the energy meter;
a function of controlling the first interface unit to send the meter-reading data to the upper device; and
a function of controlling the third interface unit to send the meter-reading data to the communication terminal,one of the first interface unit and the second interface unit being a wired communication unit configured to perform power line communication using the distribution line, andthe other of the first interface unit and the second interface unit being a wireless communication unit configured to perform second wireless communication using an electric wave.

Abstract
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.
