Description

Description: TECHNICAL FIELD The present invention relates to a method for maintaining data relating to equipment to be monitored / controlled in, for example, a centralized power monitoring and control system.

B. Summary of the Invention The present invention is a database of a computer system for monitoring and control, which defines the equipment to be monitored and controlled, specifies a processing method, and maintains data for equipment data such as a CRT screen format and a form format. In the method, data on equipment that will be transferred in the future can be
By saving these screens in units of screens and incorporating these data into the online facility database to create a simulated facility database at the time of the scheduled transfer, and conducting software tests in advance using this database, Transfer of equipment data and data maintenance can be performed before the remodeling time or before the change of the form format etc. due to operation change,
In addition, the capacity of the memory for storing data can be reduced.

C. Prior Art For example, in a centralized power monitoring and control system, there is a case where the equipment to be monitored / controlled is moved (added, changed or deleted). In this case, it is necessary to change the equipment data in accordance with the equipment change, and to test whether the specified items are correctly displayed on the CRT screen after the change or whether the form format is printed correctly. is there. In the past, because the database was only for online use, it was not possible to transfer equipment data in advance, and to avoid stopping online work being performed and testing equipment data At the same time, a test of equipment data after the transfer corresponding to the modification of the monitoring and control equipment was performed at the same time.

D. Problems to be Solved by the Invention However, the restriction that the timing for performing the transfer of equipment data and the test must be synchronized with the timing of the transfer of equipment as in the past may cause difficulty in assigning workers, and that There is a problem that the burden on the operator is large because the time for remodeling and testing is restricted. In addition, since the display contents of the screen requested by the user cannot be checked in advance by the computer system actually used, it is inconvenient because only the drawings can be checked.

An object of the present invention is to provide a data maintenance method capable of solving such a problem.

E. Means for Solving the Problems The present invention is a computer system database for monitoring and control, which defines equipment to be monitored and controlled, specifies a processing method, equipment data such as a CRT screen format and a form format. In the data maintenance method, the equipment data at the time of the scheduled transfer is created and stored in advance, using the data of each equipment and the current equipment data. Is created in advance, and a software test is performed in advance using the equipment data after the transfer, and when the equipment transfer is actually performed, the transfer data relating to the equipment transfer is incorporated into the equipment data at that time. The transfer equipment data whose scheduled transfer is at time Tn first includes all the transfer data whose scheduled transfer is before Tn and the current A pseudo online database immediately after Tn is created by using the online database, and then the pseudo online database is created by applying the transfer information of the equipment performed in Tn to the pseudo online database. .

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. The system management device 3 saves facility data relating to each facility to be monitored and controlled in the first memory 4 as a facility database, and the computer 1 copies the facility database to the memory 10 of the computer 1 and uses this. Perform predetermined data processing. The equipment database includes source data and object data.

Reference numerals 5 and 6 denote a second memory and a third memory, respectively. The second memory 5 stores transfer equipment data relating to the equipment to be changed in the future at the time of the change and at the processing unit of the equipment. It is created and stored in advance. The transfer facility data is data including only a transfer target portion, and includes a construction subject name, a subject number, a scheduled work date and time, a CRT display screen number including the transfer target portion related to the transfer, and the like. In this example, the transfer facility data is created in units of screens, but is not limited thereto, and may be created in units of one 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 works scheduled to be carried out after the present time is n, the time when the n-th work is performed in chronological order and the simulated facility database are stored by the data development unit 7 in the system management device 3 at present. Is created in combination with the equipment database of each of the first to n-th works and, specifically, data such as screens including the changed part is replaced. The source data and the object data are also expanded in this pseudo equipment 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, as described above, the test associated with the n-th construction is performed by combining the current database and each transfer data relating to the first to n-th constructions to create a pseudo-database for the future, and to create a second database. The data is stored in the memory 6, copied to the memory 11 of the computer 2, and is executed by the simulation execution unit 8 in the computer 2 using the 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. Then, when the n-th construction is actually performed at the scheduled time, the data development unit 7 creates a post-transfer equipment database based on the transfer equipment data relating to the work and the equipment database at that time, and stores the data in the first memory 4. The database is stored, and thereafter, the database is copied to the memories 10 and 11 of the computers 1 and 2, so that the online business is performed. This means that the simulated equipment database at the time of the test performed in advance can be used as an actual online database after the completion of the construction, but for that purpose, all the transfer data related to the construction before the nth construction is concerned. It is necessary that a similar test be performed for As for the reason, if the test is not performed on the transfer equipment data related to the previous construction, the test of the database itself to which the transfer equipment data related to the n-th work is to be applied has not been completed. This is because no test has been performed on the simulated equipment database created in anticipation of the n-th construction time.

Next, a method of creating the transfer facility data (n) related to the n-th construction will be described with reference to FIG. First, when the (n-1) th construction is completed by the data developing unit 7 based on the transfer equipment data (1) to (n-1) relating to the first to (n-1) th construction and the current facility database. Then, a pseudo online database (n-1) is created, and then the change information of the equipment which is the n-th construction target is input into the memory 5 using a man-machine device (not shown). As a result, the transfer facility data (n) is created by the data creation unit 9 based on the input transfer information and the pseudo database.

As described above, it is checked whether or not improper changed facility data is input when the pseudo facility database is developed using the changed facility data and the current facility database. As a result of such a check, for example, if there are a plurality of data instructed to be removed for the same equipment in a plurality of construction subjects, the data other than the first transfer equipment data is excluded as being erroneous.

It should be noted that the memories 4, 5, and 6, the data development unit 7, and the data creation unit 9
Can be treated as a function of the computer 1 or the computer 2.

Since the computers 1 and 2 may be exchanged between the master system and the slave system, the memory 10 for storing the online facility database and the memory 11 for storing the pseudo online facility database are provided.
Is installed in each of the computers 1 and 2, the test efficiency can be further improved.

G. Effects of the Invention The present invention creates a simulated equipment database at the time of a transfer by storing data on equipment scheduled to be changed in the future, for example, on a CRT screen basis, and incorporating these data into the current equipment database. Since the equipment data test is performed in advance using the software, the transfer of the equipment data and the time to perform the test can be freely selected without adjusting to the hardware construction time, and the time is limited. Since the assignment is not performed, there is no difficulty in assigning the workers, and the burden on the 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. In addition, data corresponding to equipment changes
For example, since the image data is saved in units of screens including the transfer part, the memory capacity can be small.
