On the other hand, the remote surveillance control target stabilized by the normal process shows a change that is consistent with the change of load or demand. These changes have characteristics that are time-based, day-of-week or seasonal, and do not deviate largely from the normal prediction range. Using these characteristics, it is possible to confirm whether the monitoring control operation is normally operated through appropriate prediction in the field where the instrumentation control system such as water and wastewater treatment is used, and the optimum time and energy can be used Can be monitored and controlled.

However, in a conventional remote monitoring control object, when a sensor of a monitoring system or a failure of a signal transmission system occurs, even if normal control is performed, the obtained monitoring information shows a specific change that does not depend on the control situation. Accordingly, when the operator of the monitoring and control system recognizes such a situation and fails to respond in a timely manner, a problem such as a control failure, a system congestion, and a large amount of defects occurs.

Referring to FIG. 4, the operation of the remote monitoring device based on the prediction information according to the embodiment of the present invention starts with a step of obtaining history information (i.e., second state information) (I.e., the first state information) and the setting information (i.e., the control command information) (S10) and activates the prediction algorithm (i.e.

Then, when a condition for generating an alarm by the prediction algorithm is satisfied (S30), an alarm is generated (S35). At this time, history information and trend information generated in real time and setting information by the administrator are reflected to the prediction algorithm (S40) and applied to the next round processing.

The prediction algorithm starts from the setting of the time information and the history information (S21, S22). At this time, since the prediction algorithm is based on the history information and the trend information, the information and the time of the existing server should be synchronized.

The prediction algorithm is activated when a monitoring period for the periodic prediction monitoring comes (S23).

Then, based on the history and trend information collected up to the previous cycle, a predicted maximum change value to be changed until the next cycle is calculated (S24).

Then, when the information S25 collected in the present period exceeds the estimated change maximum value (S26), the difference value is calculated by comparing the history and trend information collected in the present arrival period with the estimated change maximum value.

Then, it is determined whether the difference value is divergent or convergent for the reference time (S260). At this time, the divergence type is a case where the difference value continues to increase, and a case where the difference value continuously decreases.

Then, when the difference value is determined to be a divergence type, the duration is set (S261). Thereafter, the divergence duration from the start of the divergence to the present is compared with the return limit time (S262) When the time is exceeded, the first alarm signal (i.e., the preliminary alarm-A) is generated (S263).

If the difference value is determined to be convergent, the number of repetitions is set (S265), and the number of repetitions of divergence and convergence is calculated and compared with the maximum number of repetitions (S266). If the difference exceeds the maximum number of repetitions, And generates an alarm signal (i.e., a preliminary alarm-B) (S267).

At this time, the first alarm signal shows a sudden change in comparison with the existing cumulative trend, and the second alarm signal has a form similar to the cumulative trend in the long term, but shows a situation where the sudden change and convergence are repeated in the short term.

On the other hand, in this system, malfunction of the system due to failure of the monitoring system can be judged by predicting the result depending on the control situation and the control object. In other words, the system tends to rise or fall separately from the control level, or conversely, the situation where the result of the control execution is not reflected in the monitoring is recognized by the judgment algorithm based on the prediction information, Alarms can be generated.

Through the above-described process, the prediction server apparatus 30 can prevent a control system error due to a failure of the monitoring system or the acquisition of erroneous information, thereby improving the stability of the remote monitoring and control system.

According to the present remote monitoring and control system based on the prediction information according to the above-described process, it is possible to reduce the investment for improving the existing system by collecting and operating the monitoring control information while maintaining the configuration of the existing remote monitoring control system , The stabilization step of the system can be minimized. In addition, the remote monitoring control system based on the prediction information analyzes the monitoring control tendency according to accumulated state information, and minimizes the idle operation of the monitoring control system and the preliminary operation according to the process based on the analyzed trend information, It is possible to minimize the reserve amount according to the reaction delay time of the control object such as the quantity, the water level, and the pressure, which are managed by the management, and the energy saving effect can be realized accordingly. In addition, the remote monitoring and control system based on the prediction information can recognize an abnormal state of the system at an early stage to generate an alarm, prevent the occurrence of failure, reduce the down time of the system, and ensure stable operation .
