Control apparatus, communication system, control method and program

A communication system comprising a distributed station and a control device, wherein

• the distributed station comprises a notification processor that notifies information related to one or more events occurred within a predetermined time period at a predetermined notification frequency, and
• the control device comprises
• an acquisitor that acquires the information,
• an information analyser that executes analysis processing on the information,
• a frequency derivator that derives an occurrence frequency of the information,
• a load derivator unit that derives a load of analysis processing of the information, and
• a frequency controller that controls the predetermined notification frequency with a frequency lower than the occurrence frequency as an upper limit on the basis of at least one of an analysis result of the information, an occurrence frequency of the information, and a load of analysis processing of the information.

A control method executed by a control device, the control method comprising:

• acquiring information from a distributed station that notifies the information related to one or more events occurred within a predetermined time period at a predetermined notification frequency;
• executing analysis processing on the information;
• deriving an occurrence frequency of the information;
• deriving a load of analysis processing of the information;
• and
• controlling the predetermined notification frequency with a frequency lower than the occurrence frequency as an upper limit on the basis of at least one of an analysis result of the information, an occurrence frequency of the information, and a load of analysis processing of the information.
