Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant operation support system for monitoring the operation and status of a plant such as a power plant, a waste treatment facility, a chemical plant, and the like, and managing the associated work.

[0002]

2. Description of the Related Art A plant operation support system having a configuration as shown in FIG. 13 is employed for performing and managing irregular operations and important operations in a periodic inspection of a plant. This plant operation support system is roughly divided into a work form management device 10 and an operation operation monitoring device 30, and supports the operation and status monitoring of the plant and the management of the work associated therewith.

[0003] The work slip management device 10 registers an operation target tag, an operator, and parameters to be checked during work in an irregular operation or an important operation of a plant in a work slip database 1 and issues a work slip 2. A work form data editing means 3 for performing such editing, a display processing means 4 for performing predetermined display processing, and a CRT 5 capable of displaying data.

[0004] The operation monitoring unit 30 is provided with a process data input unit 2 for inputting process data from a plant.
1, a tagging data editing unit 22 for editing tagging data such as operation prohibition / cancellation for an operation tag, a display processing unit 23 for performing a predetermined display process, and data can be displayed and operated. And a CRT 24.

Here, the driving operation monitoring device 30 has recently
A digital control system mainly using a T touch operation is used. For example, in the operation screen 60 shown in FIG. 14, the waste liquid is stored in the tank A, and the waste liquid is usually filtered from the pump P101 by the filter F101 mainly located between the valves W001 and W002 provided in the waste liquid treatment line. And then discharge.

At this time, the filter F101 may be replaced at the time of inspection of the plant or the like. After checking the state of the solution from the values of sensors such as a rate meter, the valves W001 and W002 are fully closed, and the valve W010, which is not normally used, is opened.
By means of 2, it is possible to implement work prohibition tagging and to keep other operators inoperable.

In this case, when a tag is attached, a message such as "under inspection" is displayed on the tag display pattern 61 as shown in FIG.
This is displayed at T24, and the operation can be prohibited.
After the operation is completed, the tagging data editing unit 22 releases the tagging in the operation prohibited state. The wallet operation itself can be set to an operation permission state by providing a key switch on an operator console or the like of the control system.

[0008]

When such an unsteady or important operation is performed, an operator designated in advance follows a predetermined procedure, checks the plant state sufficiently, and then performs an operation. It is important for work management not to perform unscheduled work such as limiting the target equipment.

[0009] However, the work slips are managed in a database or the like, but are separated from the tagging operation of the tag in the actual operation, and it is only a human system to select which tag to perform the tagging operation. I had to rely on the check.

Further, since the final operation is performed by a human system check, only the operator and the administrator who are authorized to perform the operation should perform the operation. However, there is a possibility that other operators can perform the operation. Was. In addition, the management by the key switch cannot perform the management corresponding to a plurality of works and the work of each worker, and the key itself may be stolen.

In addition, since the operation is non-stationary, it is highly necessary to operate after confirming that the process state is more conservative (safer) than a normal alarm set value from the viewpoint of safety. There is a high need to operate after confirming that the plant is in the state, and there is a possibility that the plant state may be overlooked or mistaken.

Although it is possible to change the logic and set values for that purpose, it is inefficient to perform such measures on an unstable operation, and it cannot be said that it is advantageous. Further, the actual performance of the work and the like are recorded on a work slip by recording it with a memo, and the work is returned and managed after the work is completed, so that complicated work is required.

Here, the driving operation monitoring device 30 and the work form monitoring device 10 can be connected by a LAN such as Ethernet (Ethernet), and correspond to editing, addition of transmission processing, and irregular operation for each data. It is possible to support management by adding an interlock as a mode, etc.
In particular, the operation monitoring device 30 mainly performs operation of a plant and monitoring of a periodic parameter, and there is a possibility that another disadvantage such as addition of complicated processing, increase in load of the device and increase in storage capacity may occur.

According to the present invention, in order to solve the above-mentioned problems, an identification operation based on a data designation operation procedure registered by an operator is permitted under a certain condition at the time of registering a work slip without impairing the operation monitoring function of the plant.
