Data extracting apparatus, data extracting method, and recording medium

A data extracting method to be executed by a data extracting apparatus, the data extracting apparatus comprising:

• a processor configured to execute a program;
• and
• a storage device configured to store the program,
• the data extracting apparatus being configured to access:
• configuration information that defines a work environment including a group of sensors;
• and a data extraction rule, which is used for extraction from the configuration information, and is defined for each event that indicates one of a change and abnormality of the work environment,
• the data extracting method, which is executed by the processor, comprising:
• detecting a specific event based on sensor data from the group of sensors;
• extracting related data related to the specific event from specific configuration information corresponding to an acquisition time of the sensor data out of the configuration information, based on a specific data extraction rule corresponding to the specific event detected in the detecting;
• and
• outputting the related data extracted in the extracting;
• wherein the configuration information comprises machine configuration information that defines, in a graph form, a hierarchical relationship among the group of sensors and a group of machines that are installed or movable in the work environment.

A computer-readable recording medium having recorded thereon a data extraction program to be executed by a processor,

• the processor being configured to access:
• configuration information that defines a work environment including a group of sensors;
• and a data extraction rule, which is used for extraction from the configuration information, and is defined for each event that indicates one of a change and abnormality of the work environment,
• the data extraction program causing the processor to execute:
• detection processing of detecting a specific event based on sensor data from the group of sensors;
• extraction processing of extracting related data related to the specific event from specific configuration information corresponding to an acquisition time of the sensor data out of the configuration information, based on a specific data extraction rule corresponding to the specific event detected by the detection processing;
• and
• output processing of outputting the related data extracted by the extraction processing;
• wherein the configuration information comprises machine configuration information that defines, in a graph form, a hierarchical relationship among the group of sensors and a group of machines that are installed or movable in the work environment.
