Abstract

PURPOSE: To simutaneously prepare the correct procedures through plural terminals in a simultaneous preparing system of plural procedure tables which accumulates the simulated states of operation procedures to prepare a future pre-operation state and then prepares the operation procedure tables based on the pre-operation state for such jobs that maintain and check the facilities and equipments of a substation. CONSTITUTION: A CPU includes a simulated state management device in every process and an item name/simulated state management device at a common data part. The simulated state management device defines the initial state shown by the item name/simulated state management device as a temporary initial state and prepares a procedure and a post-operation state (S2 ). Then a first initial state is compared with the temporary initial state, so that it is decided whether the procedure is affected or not (S3 , S4 ). When the procedure is not affected, the procedure and the post-operation state are registered in a data base (S5 , S7 ). When the procedure is affected, a new procedure is prepared based on the latest state (S8 ).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for simultaneously creating a plurality of procedure tables in a system for stacking simulation states of operation procedures to create a future pre-operation state and creating a substation operation procedure table based on this state. Regarding

[0002]

2. Description of the Related Art A substation operation procedure table is created for maintenance and inspection of substation facilities and equipment, and a series of switch operation and confirmation procedures for stopping and using certain equipment. Consists of. The operating procedure table is usually 1 to
Created two weeks ago. The operation procedure table is created automatically or semi-automatically by the decision table method or the expert system.

Since this procedure table is prepared in advance of the day of operation, it is necessary to predict the state of the switch and the switchgear of the substation immediately before the operation in order to prepare the procedure. In the substation operation procedure table automatic generation expert system, the procedure table created by the system is simulated inside to create the substation simulated state after operation, and by stacking this, the future simulation state is created. There is.

Here, an example of a method of creating an initial state at the time of operation is shown in FIG. In FIG. 4, (1) is the present time = procedure 1
Before operation, (2) after operation of procedure 1 = before operation of procedure 2, (3) after operation of procedure 2 = before operation of procedure 3, (4) after operation of procedure 3 State = represents the state before the operation at the time of the operation.

Since the operation procedure handles a stop operation called a stop subject and a use operation as a set, the post-operation state of the stop operation and the post-operation state of the use operation are actually created.

[0006]

It is desirable to create the procedure table at the same time because there are many cases where 20 to 30 procedures tables are created per day, and the time for creating the procedure table is limited to night time. . In the system that creates the future simulated state and creates the initial state of procedure creation like the current method,
In order for more than one person to create a procedure table, it is necessary to configure the system as shown in Fig. 5 and put the procedure table created by each terminal and the substation simulation state created by it in a common database. There is.

FIG. 5 (a) shows a configuration in which a plurality of applications are activated by one CPU and each is displayed on a terminal, and FIG. 5 (b) is a configuration in which the applications are activated by a plurality of CPUs and a simulated state, etc. It is the configuration to access the shared data of the server.

However, with this method, when a procedure table is being created at one terminal, the initial state is uncertain if a procedure that is later than the operation date and time of the procedure table being created is created. The validity of the created procedure table is lost. For example, in FIG. 4, when the procedure 3 is being created, the state (4) is undetermined, and therefore the accurate procedure cannot be created.

If the database is locked during the procedure creation in order to make the simulated state consistent for each terminal operation, the procedure table cannot be created on multiple terminals at the same time. It will be the same as operating with one terminal.

The present invention has been made in view of the above points, and an object thereof is to provide a simultaneous preparation method of a multi-procedure table capable of preparing a correct procedure even if a procedure is simultaneously prepared by a plurality of terminals. It is in.

SUMMARY OF THE INVENTION The present invention accumulates simulated states of operation procedures to create a future pre-operation state, and based on this state, for maintenance and inspection of substation facilities and equipment. In the method of simultaneously creating a multi-procedure table for creating the operation procedure table, a simulated state management device is provided inside each process of the CPU, and a subject / simulated state management device is provided in the common data section. The simulated state management device creates a procedure creation and post-operation status with the initial state shown by as a temporary initial state, and at the end of the creation, compares the latest initial state with the temporary initial state and affects the procedure. It is characterized by judging whether or not there is no influence, registering the procedure and the post-operation state in the database, and when there is an influence, re-creating the procedure based on the latest state.

[0012]

[Operation] Before the procedure is created and after the procedure is created, the pre-operation states are compared with each other, and the procedure is not recreated when the status is changed within the range that does not affect the procedure creation. Creation time is shortened and the procedure can be created by multiple people.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the present invention, in order to simultaneously create a procedure table from a plurality of terminals, each process is provided with simulated state management devices 11a to 11d, and the common data section is provided with subject / simulated state management devices 12a and 12b, respectively. The procedure is created according to the flowchart shown in FIG.

First, in step S ₁ , when creating a procedure,
The initial state for creating a procedure from the time when the device is operated is referred to by the subject / simulated state management devices 12a and 12b, and the simulated state management devices 11a to 11a in each process are referred to.
Copy it to 11d.

Next, in step S ₂ , each process creates a procedure with the copied state (state A) as a temporary initial state. After the procedure is created, the simulated state management devices 11a to 11d in the process internally execute the procedure to create a new post-operation state (state B). At this time, the devices operated by the created procedure are marked and distinguished.

[0016] at the time the procedure creation and the creation of post-operation state has been completed, query the simulated state (state A ') at the operating time time again subject, mock state management apparatus 12a, to 12b (step S _3, step S ₄ ), If there is no difference from the state (state A) referred to before the procedure is created, the procedure and the state after the operation are registered in the database as they are (step S ₅ ).

[0017] If step simulated state after procedures created before creation is different (i.e., if the procedure table at the same time another terminal is created), engineered devices in the procedure in step S ₆ (marked equipment) Check the state, if there is no change in the state of the marked equipment, the procedure to register it as no effect on the procedure (step S _7). However, as for the simulated state, as shown in FIG. 3, the state of only the marked device in the post-operation state (state B) after creation is merged with the pre-operation state (state A ′) to obtain the correct simulation state (state C). Create and register.

[0018] If the state of the equipment to operate in the procedure created before the pre-operation state pre-operation state at the time of (state A) to the procedure after it is created (state A ') is different, as state failure (step S ₈₎ latest Recreate the procedure again based on the state of.

In the case of a subject in which a stop operation / use operation is a set, comparison and reflection are performed before and after each operation. In a normal stop subject, the operation procedure used is basically returned to the state before the stop operation, so the pre-stop operation state and the post-use operation state are compared, and if the simulated state is the same, the created procedure is the other stop subject. Has no effect on. However, if the pre-operation state and post-operation state are different, such as the subject of stop only or use only, the subject / simulated state management device 12a, 12b is more likely than the subject to change because the state before the operation of another subject changes. Extract the subject to be operated in the future and recreate the procedure.

In this way, the pre-operation states are compared before and after the procedure is created, and the procedure is not recreated when the status is changed within a range that does not affect the procedure creation. The procedure creation time in the field will be shortened and the procedure will be created by multiple people.

[0021]

As described above, according to the present invention, the simulated state management device is provided inside each process of the CPU, and
A subject / simulated state management device is provided in the common data section, and the simulated state management device creates a procedure and a post-operation state with the initial state indicated by the subject / simulated state management device as a temporary initial state. The latest initial state and the temporary initial state are compared to determine whether or not the procedure is affected.If there is no impact, the procedure and the post-operation state are registered in the database. Since the procedure is made again based on the state, the following excellent effects can be obtained.

(1) It is possible for a plurality of people to create a procedure at the same time, and even if a procedure needs to be recreated due to a change in state, the procedure with the corresponding subject is created.

(2) It is necessary to recreate the procedure even if there is a change in the initial state, because it is determined whether or not the procedure needs to be recreated by referring to the range in which the simulated state and the operating procedure affect. There are many cases where there is no.

(3) Since the system collectively manages the future state of the substation, the correct procedure can be created even if the procedure is created simultaneously by a plurality of terminals.
