<p>PURPOSE: An energy usage amount monitoring system is provided to accurately monitor and control the energy usage amount of a site remotely. CONSTITUTION: An energy usage amount monitoring system comprises an ubiquitous sensor network device(10), a data relay device(20), and an energy monitoring server(30). The ubiquitous sensor network device is connected to an instrument measuring an energy usage amount, acquires energy usage amount data, and transmits the data wirelessly. The data relay device transmits data through Ethernet communication after communicating with a ubiquitous sensor network wirelessly and collecting energy usage amount data. The energy monitoring server acquires and analyzes the energy usage amount data transmitted from the data relay device and controls the energy supply and break of a production system based on the analyzed data.
