Problems solved by technology

[0006] However, in the technology disclosed in the above-mentioned patent documents, although the header part in the data packet is not stored, the variable storage area can be saved. However, since most of the payload parts constituting the data packet are still stored in the variable storage area Therefore, as a countermeasure to realize low power consumption, miniaturization, and cost reduction of the command processing device, it may not be perfect

[0025] figure 1 It shows an example of a system configuration including lighting equipment connected to one embodiment of the present invention. This system is configured including a control device 310 as an information processing device and a command processing device 301 . The wireless network 309 communicably connects the control device 310 and the command processing device 301 .

[0026] The control device 310 is a device that controls the lighting device 308 by controlling or monitoring the command processing device 301 . Specifically, the control device 310 is, for example, a remote controller or the like that transmits command data by wireless communication such as infrared rays or radio waves. The control device 310 may be a computer such as a personal computer including a CPU or a memory. For example, it may be a dedicated control device that automatically controls lighting equipment according to changes in external illuminance.

no. 2 approach

[0066] Next, as a second embodiment of the present invention, the command processing device 301 of the present invention capable of handling a more complicated protocol than the first embodiment, that is, a more complicated packet format, will be described. In this embodiment, the configuration of the command processing device 301 is the same as that of the first embodiment. figure 1 The shown configurations are the same, but the programs stored in the variable memory 322 are different.

[0067] In a general protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol), it is composed of multiple protocol layers, and a packet defined by a higher-level protocol is generally stored in a packet of a lower-level protocol. part.

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.

Description

technical field [0001] The present invention relates to a command processing device and a control method of the command processing device. Background technique [0002] Various methods such as Internet Protocol (IP) are being standardized as wired or wireless interconnection methods between electronic devices, and a large number of electronic devices incorporating command control devices based on the above methods are commercialized. We are developing the above-mentioned command processing device to be installed in various equipment such as portable information equipment, mobile phones, AV (Audio Visual) home appliances, white goods, various sensor equipment, fixed equipment, mainframe computers, and personal computers. Among them, for example, a command processing device for connecting portable electronic devices, small home appliances, sensor devices, etc. to a network requires miniaturization and low power consumption. [0003] A low cost is required for a command proces...
