Description

Electrical devices The present disclosure relates to an electrical device, and more specifically, to an electrical device capable of reliably performing scalable data communication. Electric appliances can be household appliances such as washing machines, refrigerators, and air conditioners. As the functionality of electrical devices becomes more advanced, various functions are being added to them. To this end, multiple signal processing devices are used within the electrical device, and data communication is performed between each signal processing device. For example, when using UART (Universal Asylumunous serial Receiver and Transmitter) communication, which is an example of serial communication, for data communication between signal processing devices, data is transmitted in a cascade manner, so as the number of signal processing devices increases, there is a disadvantage that data communication becomes less smooth. FIG. 1 is an example of a configuration diagram of an electrical equipment system including an electrical device according to an embodiment of the present disclosure. FIGS. 2a to 2e are drawings illustrating various examples of the electrical device of FIG. 1. FIG. 3a is an example of an internal block diagram of an electrical device related to the present disclosure. Figure 3b is a drawing referenced in the description of Figure 3a. FIG. 4 is an example of an internal block diagram of an electrical device according to one embodiment of the present disclosure. FIGS. 5 to 11 are drawings referenced in the description of FIG. 4.

The suffixes "module" and "part" for components used in the following description are assigned solely for the ease of drafting this specification and do not inherently confer any particularly significant meaning or role. Accordingly, the terms "module" and "part" may be used interchangeably. FIG. 1 is an example of a configuration diagram of an electrical equipment system including an electrical device according to an embodiment of the present disclosure.

Meanwhile, the server (500) can provide data to an electrical device (200) connected via a network, etc. For example, the server (500) can provide update information to the electric device (200) at the request of the mobile terminal (600). As another example, the server (500) can provide update information to the electric device (200) when necessary, even if there is no request from the mobile terminal (600) or the electric device (200). Meanwhile, update information may include firmware update information, software update information, etc. An electric device (200) according to one embodiment of the present disclosure comprises a first signal processing device (410 in FIG. 4) and a second signal processing device (420 in FIG. 4).

The master communication interface (410b) transmits a first interrupt to the processor (518), and the second peripheral device communication interface (532) transmits a second interrupt to the slave communication interface (420b).
