FIG. 1 is a diagram showing an example of the overall configuration of a plant to which the monitoring and operating device according to the present invention is applied. ] No. (-J to omit the explanation, and only the different parts will be described here. In other words, the monitoring operation device of this embodiment has this in place of the control device 3 and manual operation device 4 in FIG. 4. It is configured with a manual operation device 5 and a control device 6 which have different functions.

Here, as shown in a schematic diagram in FIG. 2, the manual operation device 5 includes, in addition to the above-mentioned automatic/manual changeover switch 41, run/stop indicator light 42, and run/stop operation switch 43.
It is equipped with a display 44 and a guidance indicator light 45. The display 44 displays at least the process amount of the plant controlled by each pump 1. Further, the guidance indicator light 45 is provided corresponding to each pump 1, and is used to provide guidance to the operator regarding operation or stopping of the corresponding pump 1.

On the other hand, the control device 6 has a function of determining which pumps 1 to operate or stop based on the operating state of each pump 1 and the process amount of the plant, and a function of operating or stopping the pump 1 in accordance with the determined contents during automatic operation. During manual operation, the pump 1 has a function of displaying the current process amount on the display 44 and outputting a guidance display of start or stop operation to the guidance indicator light 45 of the corresponding pump 1.

Next, the operation of the monitoring and operating device configured as described above will be explained using the flow diagram shown in FIG.

In FIG. 1, the control device 6 first calculates the number of operating pumps 1 based on the discharge flow rate of the pump 1 (step S1). Next, based on the operating state of the pump 1, the operating order of the pump 1 based on the pump operating time is calculated (step S2). Next, based on these calculation results, the pump 1 to be operated or stopped is determined (step S3). Then, when the automatic/manual changeover switch 41 of the manual operating device 4 is set to the automatic side (step S4), the corresponding pump 1 is automatically operated or stopped according to the content determined above ( Step S5).

On the other hand, when the automatic/manual changeover switch 41 of the manual operation device 4 is set to the manual side (step S4), the process display output is sent from the control device 6 to the display 44 of the manual operation device 5. The associated process amount is displayed, and a guidance display output is sent to the guidance indicator light 45 of the pump 1 to display operation guidance for operating or stopping the pump 1 (step S6).

That is, for example, if some abnormality occurs while some pumps 1 are currently in automatic operation, it is necessary to manually operate or stop the pumps 1. When performing this manual operation or stop operation, in this embodiment, the current related process amount is displayed as a bar or digitally on the display 44 of the manual operation device 5, and the operation is performed by the original automatic operation. Operation guidance for starting or stopping the pump 1 is displayed on the guidance indicator light 45 of the pump 1 to be operated.

In this case, if there are two or more pumps 1 that need to be manually operated or stopped, the corresponding pump 1 will be operated or stopped 1'' according to the operating order calculated by the control device 0 and 6. Operation guidance will be displayed sequentially.

As described above, the monitoring and operating device of this embodiment determines which pumps 1 to operate or stop based on the operating status of each pump 1 of the plant and the process amount of the plant, and during automatic operation, it determines which pumps 1 to operate or stop based on the determined contents. The control device 6 automatically operates or stops the corresponding pump 1, and during manual operation, the control device 6 displays the current process amount on the display 44 for the manual operation device 5.
Further, operation guidance for starting or stopping the pump 1 is displayed on a guidance indicator light 45.

Therefore, in the event of an abnormality, it is necessary to manually start or stop the operation, and conventionally, when performing this manual start or stop operation, the operator has to judge based on his experience based on the operation content of the control device. From what I have seen, manual operation is not only inferior in controllability compared to automatic control, but also requires the skill of an operator and notor, and must be operated with extreme caution. However, in this embodiment, when operating or stopping the pump 1 using the manual operation device 5, the user can follow the guidance display while checking the operating status of the plant and the process amount. -) allows for manual operation, which simplifies the operator's operations during manual operation, and also enables manual operation to be performed accurately and without errors in emergencies, eliminating all of the conventional problems mentioned above. I can do something.

It should be noted that the present invention is not limited to the embodiments described above, but can be similarly implemented in the following manner.

In the above embodiment, the case where the manual operation device 5'' is provided with the display 44 and the guidance indicator light 45 was explained as an example, but the display 44 can display not only the process amount but also failure information. Display, display of operating conditions during manual operation, and trend display to view process progress, etc., make it possible to further enhance functionality and perform more optimal manual operation.

[Effects of the Invention] As explained above, according to the present invention, equipment to be operated or stopped is determined based on the operating status of each equipment in the plant and the process amount of the plant, and during automatic operation, the equipment is determined according to the determined contents. The operation of starting or stopping the corresponding equipment is automatically performed, and during manual operation, the process amount of 1.7 is displayed, and the operation guidance for starting or stopping the equipment is displayed, so it is easy to operate the equipment. It is possible to provide an extremely reliable monitoring and operating device that displays the operating procedure for manual operation as guidance to the operator, simplifies the operator's operation, and enables accurate manual operation in an emergency without error.
