However, if the cause of the abnormality is not found in time, the defect may be enlarged, and even the unit may jump.
If the existing protection device is used for measuring abnormal variable quantity or the DCS is used for carrying out logic configuration detection, then the DCS is used for carrying out large-screen alarm, and when an operator monitors in real time, problems that a certain alarm quantity does not have a usable cable to the DCS, the DCS sampling period does not meet the real-time monitoring requirement, the logic downloading risk coefficient of the DCS in the running state is large and the like are caused, the operation is troublesome and labor-consuming, and the safety and stability of the unit are high in risk. If a fault recorder is adopted for detecting and alarming, the real-time monitoring of operation and maintenance personnel cannot be realized, so that alarm information can be omitted and cannot be found in time; if the fault recorder alarm information is transferred to a DCS system to carry out large-screen alarm, the method for monitoring the fault recorder alarm information in real time by operating personnel is not only limited by the requirement of the access quantity of analog quantity or switching quantity of the fault recorder and the fact that all the quantity of all points is not introduced, but also the condition that some alarm quantity does not have available cables to the DCS and the limitation that the sampling period of the DCS does not meet the real-time monitoring requirement. When a portable fault recorder is used for detecting and alarming, the problem that only analog quantity or switching value can be recorded in real time and threshold value judgment cannot be carried out exists, even if the problem of threshold value judgment is solved, because operation and maintenance personnel cannot monitor the problem in real time, alarm information can be omitted and cannot be found; if the threshold detection result is transferred to the DCS system to perform large-screen alarm, and the method for monitoring the operation personnel in real time needs to configure a signal cable to the DCS system to perform remote alarm, and is still limited by the problems that the DCS sampling period does not meet the real-time monitoring requirement, the logic installation risk coefficient of the DCS system is large in the operation state and the like.
