<p>PURPOSE:To enhance monitoring reliability by a method wherein the monitoring number of times is counted to judge whether monitoring is carried out over the prescribed number of times or more at every predetermined period and, when monitoring is not carried out over the predetermined number of times or more, an alarm is emitted. CONSTITUTION:A display number-of-time count part 5 counting the number of times displayed on a CRT display apparatus 4 to store the time, a timer 6 performing time control and a prescribed number-of-time setting part 7 storing the necessary number of times of monitoring within a predetermined period are provided. Then, the number of times of monitoring display is compared with the prescribed number of times of display at every control time of the timer 6. Further, a display number-of-time comparing part 8 outputting the comparing result and issuing an alarm to an equipment apparatus not reaching the prescribed number of times and a monitor screen display part 9 are provided. By this method, the confirmation of monitoring over the prescribed number of times or the scanty state of monitoring is easily found out. By this constitution, the monitoring reliability of a plant can be enhanced without relying on the experience or perception of an operator.</p> |
