Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a method for maintaining data relating to equipment to be monitored and controlled in, for example, a centralized power monitoring and control system.

B. Summary of the Invention The present invention is a data maintenance method for facility data such as definition of devices to be monitored and controlled, specification of processing method, CRT screen format, form format, etc. in a database of a computer system for monitoring and controlling. In the case of CRT
The screen is saved as a screen unit and the data is incorporated into the current online facility database to create a simulated facility database at the time of the planned transfer. Using this, the software is tested in advance, and then the system diagram format and report format are used. By performing the test of the simulated equipment data at the time of the change of the same as above, the change of the equipment data before the time of remodeling of the equipment to be monitored and controlled or before the time of changing the form format due to the operation change and Data maintenance can be carried out,
In addition, the capacity of the memory for storing data is small.

C. Conventional technology For example, in a centralized power monitoring and control system, the equipment to be monitored and controlled may be moved (added, changed, or deleted). In this case, the equipment data is also changed due to the equipment change, and it is tested whether the specified items are correctly displayed on the CRT screen after the change or whether the form format is printed correctly. There is a need. In the past, since the database was only for online, it is not possible to transfer the equipment data in advance, and to avoid stopping the online work being executed and testing the equipment data. In parallel with the modification of the equipment subject to monitoring and control, the equipment data after the transfer was tested for it at the same time.

D. Problems to be Solved by the Invention However, the constraint that the time for changing and testing equipment data must be synchronized with the time for changing equipment, as in the past, may cause labor allocation to workers, and There is a problem that the burden on the operator is heavy because the time for remodeling and testing is limited. In addition, the display contents of the screen requested by the user cannot be checked in advance by the computer system that is actually used, so that it can only be confirmed by the drawings and the like, which is inconvenient.

The present invention has been made in view of the above circumstances, in which the time for performing equipment data transfer and test is simulated in advance, and pseudo manual data is automatically generated when the actual transfer time comes. The purpose is to reduce the burden on the operator by using it.

E. Means for Solving the Problem In the database of a computer system for monitoring / controlling, the present invention defines equipment such as equipment to be monitored / controlled, designation of processing method, equipment data such as CRT screen format, form format, etc. In the data maintenance method for, the transfer data related to the equipment to be transferred (changed) in the future is created and saved in advance at the scheduled transfer time and by the processing unit of the equipment, and the transfer data is used to schedule the transfer. Create a pseudo equipment database in the above, test the software in advance using this pseudo equipment database, and when the change is actually made, incorporate the change data related to the change into the equipment database at that time. The transfer data for which the planned transfer time is Tn is the first for all the transferred data whose transfer time is before Tn. Using the data and the current equipment database, create a pseudo equipment database immediately before Tn, and then transfer the transfer data created by applying the transfer information implemented in Tn to this pseudo equipment database. It is created by using the CRT system diagram or a pseudo equipment database of the change information of the form, and then applying the change information to be executed at the time of the change to this pseudo equipment database of the system diagram and the form. It is something.

F. Embodiment FIG. 1 is a configuration diagram showing an example of hardware of a centralized power monitoring and control system for implementing the method of the present invention. In the figure
1 and 2 are computers that are duplicated with each other. One computer 1 belongs to the main system that executes online tasks, and the other computer 2 performs tasks such as performing tests using a pseudo equipment database. Belongs to the subordinate responsible. Reference numeral 3 denotes a system management device, which has a function of managing equipment data and switching recognition of the main and sub systems of the computers 1 and 2. This system management device 3 saves data relating to each facility to be monitored and controlled, the CRT system diagram and the form as a facility database in the first memory 4, and the computer 1 copies this facility database to the memory 10 of the computer 1. Using this, predetermined online real-time data processing is performed. The equipment database includes source data and object data.

Reference numerals 5 and 6 are a second memory and a third memory, respectively. In the second memory 5, the equipment to be changed in the future, the CRT system diagram, and the change data related to the form are stored at the scheduled change time and the equipment, It is created and saved separately for each processing unit of CRT system diagram and form. The transfer data is data including only the target part of the transfer, and includes the construction case name, the subject number, the scheduled work date and time relating to the transfer, the number of the CRT display screen including the target part of the transfer, and the like. In this example, the transfer data is created for each screen, but the present invention is not limited to this, and may be created for each design drawing, for example.

The second memory 6 is for storing in advance a pseudo online facility database used for testing facility data performed before construction. For example, assuming that the number of constructions scheduled to be performed since then is n, the simulated equipment database when the nth construction is performed in time series is currently performed by the data expansion unit 7 in the system management device 3. Is created by combining the equipment database and the transfer data for each of the first to nth constructions, and specifically, the data such as the screen including the transfer portion is replaced. Source data and object data are also developed for this pseudo database. The source data is expanded before the object data.

The test of the transfer equipment data is performed as follows before the corresponding construction is performed. For example, in the test associated with the n-th construction, as described above, the database for the future is artificially created by combining the current database and each transfer data relating to the 1st to the n-th construction to create the second database. The simulation is executed by the simulation execution unit 8 in the computer 2 by storing it in the memory 6, copying it to the memory 11 of the computer 2, and using this database. For example, it is carried out by displaying the screen of a CRT and checking whether the display is correct or not, and whether or not it is easy to see. When the n-th construction is actually performed at the scheduled time, the data expansion unit 7 creates the equipment database after the movement based on the movement data relating to the construction and the equipment database at that time, and creates the first memory. 4 and thereafter, this database is copied to the memories 10 and 11 of the computers 1 and 2 to perform online business. This means that the simulated equipment database at the time of the test carried out in advance can be used as an actual online database after the construction is completed. For that purpose, all the movement data related to the construction before the n-th construction is required. Against
It is necessary that similar tests be performed. The reason for this is that if the transfer data related to the previous work has not been tested, the test of the database itself on which the transfer data related to the nth work should be applied has not been completed, so the nth This is because the simulated equipment database created by anticipating the construction time of No. has not been tested.

Next, a method of creating equipment (n) -th equipment, system diagram, and form transfer data (n) will be described with reference to FIG. First, the data expansion unit 7 starts from the first to n.
-Change data (1) to (n-1) for the 1st construction
A pseudo-online database (n-1) at the time when the n-1th construction work is completed based on the current equipment database and the current equipment database, and is the nth construction target using a man-machine device (not shown). Equipment transfer information is input into the memory 5. With this result data creation unit 9,
Based on the input transfer information and the pseudo database, transfer data (n) relating to the equipment is created.

In the above, when the pseudo equipment database is expanded by using the movement data and the current equipment database, it is checked whether or not the illegal movement data is input. As a result of such a check, for example, if there are a plurality of data instructing the removal of the same equipment in a plurality of construction subjects, the data other than the first transfer data is excluded as an error. The transfer data (n) relating to the equipment created as described above is again set to 1 by the data expansion unit 7.
Pseudograph at the time when the (n-1) th change is completed based on the change diagrams (1) to (n-1) related to the system diagram and the form related to the (n-1) th change and the current online database. Create a database (n-1). Next, again using a man-machine device (not shown),
Enter the change data related to the system diagram and book that is the second change target. As a result, the data creation unit creates the change data (n) regarding the system diagram and the form based on the input change data regarding the system diagram and the form and the pseudo database. When the pseudo equipment database is developed by using the movement data created in this way and the current equipment database, it is checked whether or not the illegal movement data is input as described above. By performing such a check, data other than the first transfer data is excluded as an error, as described above.

The memories 4, 5 and 6, the data expansion unit 7, and the data creation unit 9 can be handled as the functions of the computer 1 or the computer 2.

In addition, since the primary system and the secondary system may be exchanged in the computer 1, the online facility database storage memory
10, Pseudo online facility database storage memory 11
The test efficiency can be further improved by installing the computer in each of the computers 1 and 2.

G. Effect of the Invention The present invention saves data relating to facilities, system diagrams, and forms that are scheduled to be transferred in the future, for example, in units of CRT screens, and incorporates these data into the current facility database to create a simulated facility database at the time of planned transfer. Since the equipment data is created and the equipment data is tested in advance using this, it is possible to freely select the time when the equipment data is changed and tested without matching the hardware construction time. At the same time, there is no restriction on the time, so there is no difficulty in assigning workers, and the burden on workers is small. Further, since the display contents of the screen requested by the user can be checked in advance, occurrence of trouble can be suppressed. Moreover, since the data corresponding to the equipment change is stored for each screen including the changed part, the memory capacity can be small.
