设备诊断装置
摘要：
本发明提供一种根据设备的时间系列信息，不仅用设备的工作状态，而且也加进工作环境和工作条件，推定设备的状态，并根据推定的状态诊断设备状态的设备诊断装置。该设备诊断装置具备从作为诊断对象的设备(3)接受时间系列信息，检测出时间系列信息的变化点的区间推定部件(101)、接受来自作为诊断对象的设备(3)的时间系列信息和来自区间推定部件(101)的变化点信息，将变化点作为边界在时间上分割时间系列信息，对每个分割成的区间从区间的前后关系或与其它的时间系列信息的关系推定设备(3)的状态的状态推定部件(102)、和根据推定的状态诊断设备(3)的设备诊断部件(103)。
摘要（英）：

An object of the present invention is to provide a diagnosis apparatus for diagnosing state of equipment which estimates the state of the equipment based on the time series information of the equipment considering not only the operation state of the equipment but also the operation environment and the operation condition, and diagnoses the state of the equipment according to an estimated state. The diagnosis apparatus for diagnosing state of equipment includes an interval estimation unit which receives time series information from diagnosis object equipment and detects a change point of the time series information, a state estimation unit which receives the time series information from the diagnosis object equipment and change point information from the interval estimation unit, divides the time series information temporally with the change point as a boundary, and estimates a state of the equipment from before and after relation of an interval or relation with another time series information per divided interval, and an equipment diagnosis unit which diagnoses the equipment according to an estimated state.
