Description

This invention relates to an energy management system. An energy management system is known that manages the energy of an area equipped with predetermined controlled equipment. This energy management system includes a control device capable of wirelessly transmitting and receiving control signals to controlled equipment such as lighting and electrical appliances installed within a building (see, for example, Patent Document 1). Japanese Patent Publication No. 2014-113002 Figure 1 is a block diagram showing an energy management system according to an embodiment of the present invention.Figure 2 is a schematic diagram showing an example of an equipment system.Figure 3(a) is a block diagram of the detection slave unit, Figure 3(b) is a block diagram of the control slave unit, and Figure 3(c) is a block diagram of the master unit.Figures 4(a) and 4(b) are conceptual diagrams illustrating the grouping of lighting.Figure 5 is a conceptual diagram illustrating the hopping path.Figure 6 is a block diagram showing an energy management system according to a modified example.Figure 7 is a block diagram showing an energy management system according to a modified example. The embodiments of the present invention will be described in detail below with reference to the attached drawings. In the description of the drawings, identical or equivalent elements are denoted by the same reference numerals, and redundant descriptions are omitted. Figure 1 is a block diagram showing an energy management system 100 according to an embodiment of the present invention. As shown in Figure 1, the energy management system 100 is a system for managing energy within a managed area equipped with predetermined controlled equipment 3. The energy management system 100 comprises a detector 1, a detection slave unit 2, controlled equipment 3, a control slave unit 4, a master unit 6, a management unit 7, and a user interface unit 8. Furthermore, the energy management system 100 is composed of an equipment system 101 and a network system 102. The equipment system 101 is a system that constitutes the management area of the energy management system 100. The equipment system 101 is a system that includes a detector 1, a detection slave 2, a controlled equipment 3, a control slave 4, and a master unit 6. In the equipment system 101, the detector 1 and the detection slave 2 are connected by wiring W1. The detection slave 2 and the master unit 6 are connected by power line W2. The controlled equipment 3 and the control slave 4 are connected by wiring W3. The control slave 4 and the master unit 6 are connected by power line W4. Within the equipment system 101, information is transmitted between devices by power line communication (PLC communication). Power line communication is a communication method that transmits and receives communication signals using power lines, for example, by superimposing a communication signal of a different frequency from the commercial frequency onto a power waveform of the commercial frequency and transmitting it, and by separating and receiving the communication signal of a different frequency from this power waveform. It should be noted that power line communication may be subject to the Radio Law depending on its frequency band. However, in the energy management system 100 according to this embodiment, power line communication in the frequency band of 100 kHz to 450 kHz may be used, for example, in order to be usable both indoors and outdoors and to achieve a certain amount of data transfer. However, power line communication in higher or lower frequency bands may also be used. For example, the frequency band may be 10 kHz or less, or 2 MHz or more. Also, when using power line communication in the frequency band of 100 kHz to 450 kHz, the modulation method is not particularly limited, and either the OFDM method or the DCSK method may be adopted. Power lines are primarily wiring for supplying AC power at commercial frequencies, and they serve as the transmission path when performing power line communication. Specifically, power line communication is performed between the detection slave unit 2 and the control slave unit 4 and the master unit 6. In power line communication, communication signals can be superimposed not only on AC power distribution such as AC 100V and AC 200V, but also on DC power distribution, just as with AC. When detector 1 is, for example, a motion sensor or an illuminometer, the signal from these detectors 1 may first pass through the master unit 6, and then, depending on the master unit 6's judgment, power line communication may be performed to the control slave unit 4. However, depending on the master unit 6's program, it is also possible for the detection slave unit 2 to exchange commands with the control slave unit 4 using power line communication without going through the master unit 6. Figure 2 shows an example of the equipment system 101. Figure 2 shows an example in which the energy management s
