<1. First Embodiment>
[1.1. Schematic configuration of system according to first embodiment]
First, a schematic configuration of a system according to the first embodiment of the present disclosure will be described with reference to FIG. In the present embodiment, electromagnetic inherent noise (noise: hereinafter also referred to as inherent signal) generated by the operation of the electronic circuit of the home appliance is detected. As illustrated in FIG. 1, the system according to the present embodiment includes a home appliance 100, a detection device 200, and a reception device 300. Detection device 200 is attached to the back surface of home appliance 100. The detection device 200 detects an electromagnetic wave of the home appliance 100 and transmits information related to the electromagnetic wave to the reception device 300. The receiving device 300 determines the type, operation mode, and the like of the home appliance 100 based on the received information about the electromagnetic wave, and provides the user with information about the operation of the home appliance 100, particularly information about power consumption.

  As illustrated in FIG. 1, the detection device 200 includes a loop antenna 202, a detection unit 204, and a wireless transmission unit 206. The loop antenna 202 receives an electromagnetic wave signal (specific signal) generated by the home appliance 100 and sends it to the detection unit 204. The detection unit 204 detects the electromagnetic wave, and performs a predetermined spectrum analysis. The analysis data (power spectrum) is sent from the wireless transmission unit 206 to the receiving device 300 by wireless transmission.

The spectrum of the unique signal generated from the home appliance differs for each home appliance and each operation mode. For example, an air conditioner has a large spectrum of low-frequency components due to the operation of a compressor, and the spectrum changes when the operation mode is changed, such as increasing the air volume. On the other hand, television receivers and the like process video signals and thus have a high frequency component spectrum. Therefore, the model and mode of home appliance 100 can be determined based on the spectrum of the unique signal. In this manner, the type of home appliance 100 and the operation mode of home appliance 100 can be determined by detecting a specific signal generated from home appliance 100 and performing spectrum analysis.

Here, the power spectrum transmitted from the detection apparatus 200 is acquired, but the spectrum analysis may be performed on the reception apparatus 300 side. In this case, the RF determination unit 304 can perform the spectrum analysis. RF discriminating unit 304 discriminates electromagnetic waves based on the power spectrum of the electromagnetic waves, and discriminates the model of home appliance 100. The operation determination unit 306 determines the operation mode of the home appliance 100 based on the power spectrum of electromagnetic waves. The power estimation unit 308 estimates the power consumption of the home appliance 100 based on the model of the home appliance 100 and the operation mode. The data processing unit 310 processes the estimated power consumption data and performs predetermined statistical processing such as averaging processing for each hour. The display unit 312 displays the data processed by the data processing unit 310.

  Each component shown in FIG. 2 can be configured by a circuit (hardware) or a central processing unit such as a CPU and a program (software) for causing it to function.

By comparing the power spectrum detected by the RF determination unit 304 and the RF detection unit 302 with the power spectrum stored in the storage unit 314, the model of the home appliance 100 is determined. In addition, the operation determination unit 306 determines the operation mode of the home appliance 100 by comparing the power spectrum detected by the RF detection unit 302 with the power spectrum stored in the storage unit 314.

At this time, the type and operation of the home appliance 100 are determined from the detected spectrum data pattern by pattern identification. In the next step S16, it is determined whether or not the identification has been performed normally. If the identification is performed normally, the process proceeds to step S18. On the other hand, if the identification is not normally performed, the detected spectrum may be some noise and the process proceeds to step S22.

In addition to the case where the receiving device 300 itself performs display, the display information can be transmitted to a television receiver, a mobile phone, or the like for display. In the example of FIG. 5, since the power consumption exceeds a predetermined threshold, the message “Air conditioner is overused” is displayed. Thereby, the user who visually recognizes the display unit 312 can reduce the temperature setting of the air conditioner, thereby achieving energy saving.
