Summary:To provide a data acquisition system and a data acquisition method capable of acquiring data without increasing a communication load and a processing load after recovering from an abnormality.SOLUTION: In a data linkage system, a data acquisition unit for repeatedly acquiring data at a prescribed cycle from a base providing a service performs: determination processing of, when data is not acquired due to an abnormality caused by the service or an abnormality caused by a network connecting the base and a data acquisition system, determining whether or not to acquire the data that should have been repeatedly acquired in the prescribed cycle during a period from occurrence of the abnormality until recovery, based on date and time, the prescribed cycle and a current time for the data acquired at the prescribed cycle before the abnormality occurs; and acquisition processing of, when it is determined to acquire the data, acquiring the data that should have been acquired in one cycle in an acquisition interval shorter than the prescribed cycle.SELECTED DRAWING: Figure 10 【課題】異常の復旧後に、通信負荷及び処理負荷を増大させることなく、データの取得を可能とするデータ取得システム及びデータ取得方法を提供する。【解決手段】データ連携システムにおいて、サービスを提供する拠点からデータを所定のサイクルで繰り返し取得するデータ取得部は、サービスに起因する異常あるいは拠点とデータ取得システムを接続するネットワークに起因する異常によりデータが取得できなくなった場合、異常が発生する前の所定のサイクルで取得したデータの日時と、所定のサイクルと、現在時刻とに基づいて、異常が発生してから復旧までの期間において所定のサイクルで繰り返し取得すべきであったデータを取得するか否かを判定する判定処理及びデータを取得すると判定した場合、所定のサイクルよりも短い取得間隔で、一のサイクルで取得すべきであったデータを取得する取得処理を行う。【選択図】図10
