Information processing apparatus, information processing method, and information processing system

An information processing method for processing information relating to a target device that processes a target object, the method comprising:

• acquiring detection information of a physical quantity that changes according to an operation state of the target device by transmitting an acquisition request to the target device;
• receiving, from the target device, context information in response to the acquisition request, the context information relating to an operation status of the target device;
• specifying a processing period in which the target device is processing the target object based on at least the context information and a transmission time associated with transmitting the acquisition request such that the processing period excludes at least one non-processing period;
• extracting processing period detection information from the detection information based on the processing period such that the extracted processing period detection information includes a first portion of the detection information and does not include at least one second portion of the detection information corresponding to the at least one non-processing period;
• and
• determining an occurrence of a defect relating to processing by the target device based on the processing period detection information and the context information used for specifying the processing period.

A non-transitory recording medium comprising program code that, when executed by one or more processors, cause the one or more processors to,

• acquire detection information of a physical quantity that changes according to an operation state of a target device that processes a target object by transmitting an acquisition request to the target device;
• receive, from the target device, context information, the context information relating to an operation status of the target device;
• specify a processing period in which the target device is processing the target object based on at least the context information and a transmission time associated with transmitting the acquisition request such that the processing period excludes at least one non-processing period;
• extract processing period detection information from the detection information based on the processing period such that the extracted processing period detection information includes a first portion of the detection information and does not include at least one second portion of the detection information corresponding to the at least one non-processing period;
• and
• determine an occurrence of a defect relating to processing by the target device based on the processing period detection information and the context information used for specifying the processing period.
