Abstract

A command processing device includes: a command reception section for receiving command data formed by a plurality of element data by successively receiving the element data; a state transition pattern storage section for storing a processing state transition pattern in the interpretation process of the command data; a state transition section for processing the element data one by one in the interpretation process of the command data and changing the processing state in the interpretation process according to the state transition pattern each time one element data is processed; and a control section for executing control according to the state finally decided by the state transition section.

Claims

1. A command processing device comprising:

a command reception section for receiving command data formed by a plurality of element data transmitted from an information processing device by successively receiving the element data;

a state transition pattern storage section for storing a processing state transition pattern in an interpretation process of the command data;

a state transition section for processing the element data one by one in the interpretation process of the command data and changing the processing state in the interpretation process according to the state transition pattern each time one element data is processed; and

a control section for executing control according to the state finally decided by the state transition section.

2. A command processing device as claimed in claim 1, further comprising an element data storage section for storing element data received by the command reception section,

wherein the element data storage section stores only a part of a plurality of element data constituting the command data.

3. A command processing device as claimed in claim 1, further comprising a state storage section for storing the state to be changed by the state transition section while correlating it to the identification information added to the command data,

wherein the command reception section receives the command data divided into a plurality of element data groups by successively receiving the element data one by one for each of the element data groups, and

the state transition section reads out a state corresponding to the identification information added to each of the element data group, changes the read out state according to the state transition pattern, and stores the state changed in the state storage section.

4. A command processing device as claimed in claims 1, further comprising a radio communication interface for performing communication via radio,

wherein the command reception section receives the element data via the radio communication interface.

5. A command processing device as claimed in claim 3, wherein the command reception section receives the command data as an IP datagram according to the TCP/IP protocol, and

the identification information is an identifier specified for a header portion of the IP datagram received via the communication path by the reception section.

6. A command processing device as claimed in claim 1, further comprising a communication interface communicably connected to a home electric appliance,

wherein the control section controls operation of the home electric appliance via the communication interface according to the state finally decided by the state transition section.

7. A command processing device as claimed in claim 6, the device further comprising a transmission section for transmitting data to the information processing device via the communication path,

wherein the control section receives information from the home electric appliance via the interface according to the state finally decided by the state transition section and transmits information received from the home electric appliance via the transmission section to the information processing device.

8. A command processing device as claimed in claim 1, further comprising:

a communication interface for connection with a sensor device; and

a transmission section for transmitting data to the information processing device via the communication path,

wherein the control section receives a detection result of the sensor via the communication interface, and

the control section transmits the detection result via the transmission section to the information processing device according to the state finally decided by the state transition section.

9. A command processing device as claimed in claim 2, further comprising:

a communication interface for connection with a sensor device; and

a transmission section for transmitting data to the information processing device via the communication path,

wherein the control section receives a detection result of the sensor via the communication interface, and

the control section transmits the detection result via the transmission section to the information processing device according to the state finally decided by the state transition section.

10. A control method of a command processing device comprising a processor, a memory, a communication interface for communication with an information processing device, and a control section for controlling a controllable device, the method comprising steps of:

receiving, by the communication interface, command data formed by a plurality of element data transmitted from an information processing device by successively receiving the element data;

storing, by the memory, a processing state transition pattern in an interpretation process of the command data;

successively processing, by the processor, the element data one by one in the interpretation process of the command data and changing the processing state in the interpretation process according to the state transition pattern each time one element data is processed; and

executing, by the control section, control decided according to a state finally decided by the transition by the state transition pattern.
