    • First determination means 16 determines whether a deviation exceeds a threshold value, measurement means 17 measures the period in which the deviation exceeds the threshold value in accordance with the determination result, second determination means determines whether the period in which the deviation exceeds the threshold value continues for a certain period or more in accordance with the measurement result, third determination means 19 determines whether the absolute value of the deviation decreases, and trouble determination means 2 determines that a trouble occurs when the period in which the deviation exceeds the threshold value continues for a certain period or more and the absolute value of the deviation does not decrease.
    • 第一确定装置16确定偏差是否超过阈值,测量装置17根据确定结果测量偏差超过阈值的周期,第二确定装置确定偏差超过阈值的周期是否继续 第三确定装置19根据测量结果确定一段时间或更长时间,确定偏差的绝对值是否减小,并且故障确定装置2确定当偏差超过阈值的时间段持续时出现故障, 一定时间以上,偏差的绝对值不下降。

    • With the method in accordance with the invention at least one monitoring limit value is defined in advance for an operating variable to be monitored of the technical device. During the operation of the technical device the current value of the operating variable to be monitored is recorded at least twice at least within a finite time interval, and within the time interval a current monitoring reference value is determined by means of an interpolation between the monitoring limit value and the current value of the operating variable to be monitored. A particular advantage of the method in accordance with the invention is that monitoring of the operating variable is possible immediately after the technical device has gone into operation for the first time and that the quality of the monitoring is refined as a kind of learning process as operation proceeds.
    • 利用根据本发明的方法,对于技术装置的被监控的操作变量,预先定义至少一个监视极限值。 在技​​术装置的操作期间,要监视的操作变量的当前值至少在有限时间间隔内记录至少两次,并且在时间间隔内,通过监视之间的内插来确定当前监视参考值 限制值和要监视的操作变量的当前值。 根据本发明的方法的一个特别的优点是在技术装置第一次运行之后立即监视操作变量,并且将监控的质量作为一种学习过程作为操作来进行改进 收益。
