If the control unit 370 calculates that the file has access authority based on the administrator authority information stored in the memory 340, the control unit 370 can grant access to the file (S291).

For example, when the administrator authority is a concept including a management class assigned to each of a plurality of administrators by classifying a plurality of administrators in a rank order manner, the control unit 370 controls access to the lower- (Access), and block access to the higher-level file of the lower-level manager. Accordingly, the air conditioner 50 can protect the information, and enable integrated management of the file by the super administrator.

As another example, when the administrator authority is a concept including a task classification assigned according to the task of the developer, the control unit 370 allows the program manager developer to access (access) the program manager file, You can block access to Monitoring Manager files. Accordingly, the air conditioner 50 controls the types of files that can be accessed to be different according to the administrator authority so that the files can be effectively managed according to the administrator authority.

The connection service server 120 can receive a signal corresponding to the determined voice command from the natural language processing server 112. [

If the determined voice command is related to the home appliance, the connection service server 120 can perform a corresponding operation by communicating with the home appliance control server 130.

Alternatively, if the determined voice command is not related to the home appliance, the connection service server 120 may communicate with the external service 121 to perform a corresponding operation.

For example, if the determined voice command is a command for requesting information such as weather, stock, news, etc., the connection service server 120 requests and receives the information from the server providing the service corresponding to the requested information .

The connection service server 120 may transmit the received information to the voice server 110, and the natural language processing server 112 may transmit the received information to the home appliance.

If the determined voice command is related to the home appliance, the connection service server 120 may generate a request signal corresponding to the determined voice command and transmit the request signal to the home appliance control server 130.

In this case, the response signal based on the determined voice command transmitted from the natural language processing server 112 to the home appliance may include the processing result information.

On the other hand, the home appliance can receive a response signal based on the determined voice command from the natural language processing server 112. Here, the response signal may include text data of a response corresponding to the identified voice command.

For example, when the user inputs a voice command to change the set temperature of the air conditioner, the response signal may include text data indicating that the set temperature has been changed.

On the other hand, the home appliance can transmit a signal including the text corresponding to the received response signal to the text-to-speech conversion server 113. Here, the signal including the text corresponding to the response signal may include an output text corresponding to the processing result information.

Meanwhile, the text-to-speech conversion server 113 may convert the text included in the received signal into voice data and transmit the voice data to the home appliance. The converted voice data may include a sound source file.

The home appliance can output a voice guidance message based on voice data received through the speaker.
