    • A data storage apparatus includes a sampling device for sampling data in a predetermined cycle, and a storage device for storing a plurality of items of the data sampled by said sampling device. The data storage apparatus also includes an updating device for updating the plurality of items of the data stored in said storage device to respective ones of the plurality of items of the data, which were sampled at later times than the plurality of items of the data were stored, in respective predetermined updating cycles which are shorter than the updating cycles of the plurality of items of the data which were sampled at respective earlier times.
    • 数据存储装置包括用于以预定周期对数据进行采样的采样装置和用于存储由所述采样装置采样的多个数据项的存储装置。 数据存储装置还包括更新装置,用于将存储在所述存储装置中的数据的多个项目更新为多个数据项中的多个项目,这些数据在稍​​后时间比多个数据项目被抽样 在相应的预定更新周期中存储,其比在较早时间被采样的多个数据项的更新周期短。

    • Abnormality detection is conducted with respect to data indicative of operating state of an apparatus, the abnormality type is then discriminated and a check is made as to whether the data are already recorded in association with the discriminated abnormality type in a memory region corresponding to the data, and if not, the data are recorded in association with the discriminated abnormality type there. Since, multiple recording of similar data related to transient abnormalities and other such events that are likely to occur repeatedly can be prevented, important data related to a diversity of abnormalities and failures can be efficiently recorded in the memory. Viewed from another angle, this means that the capacity of the memory can be reduced and that a cost-reducing effect can be anticipated. In addition, data important for troubleshooting abnormalities and failures, most notably transition period data, can therefore be efficiently recorded in the memory.
    • 对指示装置的运行状态的数据进行异常检测,然后鉴别异常类型,并且在对应于数据的存储区域中检查数据是否已经与识别的异常类型相关联地被记录 ,如果不是,则与该区别的异常类型相关联地记录数据。 由于可以防止与瞬时异常有关的类似数据的多次记录和可能重复发生的其他这样的事件,因此可以有效地将与异常和故障的多样性相关的重要数据记录在存储器中。 从另一个角度来看,这意味着可以减少存储器的容量,并且可以预期降低成本的效果。 此外,因此可以有效地将记录在异常和故障中的重要数据,尤其是过渡期数据。
