Information output system, a home energy management system, method information output, and program

Discrimination system is a system for determining the operating state of the electrical device connected power from multiple power sources receivable power system. Determination system includes a measuring device (110), the information collection apparatus and a (120). Measuring device (110), the power source obtains the power information supplied to the power supply system for a plurality of power sources, respectively, and supplies electric power to meet the preset criteria based on the acquired power information to determine. The measurement device (110) acquires a current waveform for transmitting the waveform of the current flowing from the discriminated power source to the power supply system to the information collection device (120). Measuring device (110) transmits the waveform information generated on the basis of the acquired current waveform information collection device (120). Information collection device (120) acquires the waveform information measurement device (110) transmits, to determine the operating status of the electrical device connected to the power supply system based on the acquired waveform data (400).
