Abstract

PURPOSE:To relieve the load of a plant supervisor by supervising an operating section and a check section of a plant installation simultaneously at a same location. CONSTITUTION:The plant supervisory system is provided with an operation section 2 outputting a signal in the operating state of a plant installation 1 in on-line and a check state input device 12 receiving a signal in the check state of the plant installation 1. Then the signal in the operating state outputted by the operation section 2 and the signal in the check state from the check state input device 12 are received respectively by a plant supervisory equipment 11 and the state display corresponding to each signal is implemented by the same state display section. Since the state of the operation section 2 and the check section 3 of the plant installation 1 are supervised centralizingly by the one supervisory equipment 11 unifiedly, the man-machine performance is improved and the load of the plant supervisor is relieved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a plant monitoring system for plant equipment that enables simultaneous monitoring of operating parts and inspection parts of plant equipment such as a power plant.

[Conventional technology]

FIG. 5 is a block diagram showing a conventional plant monitoring system for plant equipment. In the figure, 1 is the plant equipment, 2 is the operating part of the plant equipment 1, and 3 is the part of the plant equipment 1 that is being inspected. 4 is a monitoring device for monitoring the state of the plant equipment 1, and 5 is an inspection state monitoring device for inputting and monitoring the inspection state offline by a person.

Next, the operation will be explained.

First, the state of the operating section 2 of the plant equipment 1 is input online to the plant monitoring device 4, and the operator monitors the operating state through a display device or the like. On the other hand, regarding the status of the inspection section 3 of the plant equipment 1 or the status that is being inspected, the equipment itself is being inspected, so online input is unreliable and cannot be used, so the aurator collects the status offline. , this is input into the inspection state monitoring device 5 and monitored. Thereby, the operator monitors this through a display device or the like.

[Problem to be solved by the invention]

Since the conventional plant monitoring system for plant equipment is configured as described above, plant monitors such as operators can

It is necessary to monitor the state of the plant equipment 1 using the plant monitoring device 4 while grasping the state of the inspection section 3 using the display device in the inspection state monitoring device 5. Therefore, the work for this monitoring is troublesome, and the above-mentioned plant There were issues such as a heavy workload for supervisors.

This invention was made in order to solve the above-mentioned problems, and aims to reduce the work burden on plant supervisors by making it possible to simultaneously monitor the operating parts and inspection parts of plant equipment in the same place. The purpose is to obtain a plant monitoring system for plant equipment that can perform

[Means to solve the problem]

The plant monitoring system according to the present invention includes a working unit that outputs a signal indicating the operating status of plant equipment online, and an inspection status input device that receives a signal indicating the checking status of the plant equipment offline, and the operating unit outputs a signal indicating the operating status of the plant equipment. The plant monitoring device receives the operating state signal and the inspection state signal from the inspection state input device, respectively, and displays the state corresponding to each signal on the same state display section.

[Effect]

The plant monitoring system of this invention centralizes and monitors the status of operating parts and inspection parts of plant equipment into one monitoring device, thereby improving man-machine efficiency and reducing the burden on plant supervisors. functions.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 is plant equipment, 2 is an operating part of the plant equipment 1, and 3 is an inspection part of the plant equipment 1, which are the same as in the conventional system. Further, 11 is a plant monitoring device that monitors signals of the operating status of plant equipment, which are online data of the operating unit 2, together with offline data of the inspection unit 3;
Reference numeral 12 denotes an inspection status input device that inputs a signal indicating the inspection status of plant equipment, which is offline data from the inspection section 3, to the plant monitoring device 11.

Next, the operation will be explained.

First, online data from the operating section 2 of the plant equipment 1 is input to the plant monitoring device 11. On the other hand, offline data of the inspection section 3 of the plant equipment 1 is collected by a plant supervisor and inputted into the inspection status input device 12. Therefore, the inspection status input device 12 transmits this offline data to the plant monitoring device 11. This plant monitoring device 11 has a status display section 20 such as a CRT screen as shown in FIG.
0, status displays 21 and 22 of the online data of the operating section 2 and the offline data of the inspection section 3 are distinguished and displayed simultaneously.

FIG. 3 shows the case where such status display 21, 22 is applied to the system monitoring of a concrete power plant.

According to this, the operating section 2 is indicated by a broken line, and the inspection section 3 is indicated by a solid line.

In addition, FIG. 4 is a comparison table for clearly indicating whether the specific display contents of the above-mentioned status displays 21 and 22 are those of the operating section 2 or the inspection section 3. It can also be displayed together with what is indicated.

In this way, by simultaneously displaying the status display of the inspection unit 3 and the operating unit 2 on the status display unit 20 of the plant monitoring device 11, the workload of the plant supervisor can be significantly reduced.
Furthermore, monitoring accuracy can be improved.

〔Effect of the invention〕

As described above, according to the present invention, the operating section is provided with an operating section that outputs a signal indicating the operating status of plant equipment online, and an inspection status input device that receives a signal indicating the inspection status of the plant equipment offline. The plant monitoring device receives the output operating status signal and the inspection status signal from the inspection status input device, and the status display corresponding to each signal is displayed on the same status display unit. The status of the operating parts and inspection parts of equipment, which were conventionally monitored using separate monitoring devices, can now be monitored simultaneously with a single status display section of the plant monitoring device, thus significantly reducing the burden on plant supervisors. In addition to being able to reduce the amount of noise, it also has the effect of improving monitoring accuracy.
