The communication system 80 of FIG. 18 is similar to the communication system 50 of FIG. 1 except that the communication device 100 is wirelessly connected, rather than wired to the home appliance.
That is, as shown in the drawing, the first communication between the communication device 100 and a home appliance, such as the refrigerator 200a, the washing machine 200b, the air conditioner 200c, the cooking apparatus 200d, and the like, which are located in the internal network 10, are performed. The module 110 may perform wireless data communication through WiFi communication.
Meanwhile, the second communication module 110 of the communication device 100 may receive power information from the power information transmission device 300 through Zigbee communication.
The communication device 100 of FIG. 18 may perform the operation of the communication device described with reference to FIGS. 7 to 15D as it is.
Meanwhile, the communication device 100 of FIG. 18 may manage power in the internal network 10. In this case, the communication device 100 may be called a home energy management system (HEMS).
The communication device 100 responds to the power information on the refrigerator 200a, the washing machine 200b, the air conditioner 200c, the cooking apparatus 200d, and the like based on the power information received from the power information transmission device 300. The recommended driving information can be transmitted.
For example, it is possible to generate recommended driving information to perform a specific time zone driving, and transmit it to at least one of the refrigerator 200a, the washing machine 200b, the air conditioner 200c, and the cooking appliance 200d.
On the other hand, the communication device 100 wirelessly transmits the power information received from the power information transmission device 300 to the refrigerator 200a, the washing machine 200b, the air conditioner 200c, the cooking appliance 200d, or the like. It is also possible.
The mobile terminal, the communication device, and the operation method thereof according to the present invention are not limited to the configuration and method of the above-described embodiments, but the above embodiments may be modified in various ways so that various modifications can be made. All or part may be optionally combined.
Meanwhile, the method of operating a mobile terminal or the method of operating a communication device of the present invention can be implemented as code that can be read by a processor in a processor-readable recording medium included in the mobile terminal or a communication device. The processor-readable recording medium includes all kinds of recording devices that store data that can be read by the processor. Examples of the processor-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet. . The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.
In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
