Abstract

PURPOSE:To execute the performance test in the actual operating state by using one computer as a performance testing computer and using the other as a simulation signal generating computer to simulate the state change. CONSTITUTION:A simulation signal generating computer 3 obtains external information from equipment information preliminarily defined by a data base 1 and outputs it to a DMA area 7.

In this case, the computer interface device 10 compares external information with transmission information read from the DMA area 6 for the computer 2 and sends a signal to the computer 2 at the time of detecting the change, and the computer 2 recognizes the state change of a power system by an interruption signal to execute the actual work, thus executing the performance test.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a performance testing method for a multiplexed computer system used for power system monitoring and control.

(Prior art) Conventionally, in performance tests of power system monitoring and control systems, etc., it has been common to create external information from remote monitoring and control equipment, etc., and to simulate interrupt signals for state changes using a built-in computer. Ta. In other words, by creating external information received from a remote monitoring and control device, etc. in a computer that is performing a performance test under actual operating conditions, and simulating interrupt signals generated by changes in external information, Create an environment
They were required to carry out various tasks and required computer performance.

(Problems to be Solved by the Invention) According to the conventional method described above, since an environment equivalent to the actual operating state is created, external information to be received from a remote monitoring and control device, etc. is created, and problems occur due to changes in external information. The addition of arithmetic processing to simulate interrupt signals is itself different from actual operation. Furthermore, by simulating external information within the computer, interrupt signals generated by changes in actual external information were not transmitted from the external equipment, resulting in an operating state that was different from actual operation, making it impossible to perform accurate computer performance tests. .

Therefore, the present invention creates external information on one simulation system computer and transmits it to the other test system computer, thereby simulating the generation of an interrupt signal and the state change of the external information, which is equivalent to the actual operating state. The purpose is to provide testing equipment to obtain accurate computer performance.

[Structure of the invention]

(Means for solving the problem) A configuration is established in which information can be transmitted via a remote monitoring and control device between each system of a multiplexed computer system that has the same predefined equipment information, and external information is transmitted from the simulation system to the test system. Allow information to be transmitted.

(Function) External information is created from the equipment information predefined in the simulation system, and this external information is sent to the remote monitoring and control device while changing.Furthermore, the created external information is sent from the remote monitoring and control device to the test system. . This allows a performance test that operates as if it were receiving external information collected from a remote monitoring and control device.

The transmission system bus switching device 15 is configured to switch to the transmission system bus 13 side when performing a performance test of the computer 2 and to enable transmission between the computer interface devices 10 and 11.

are sent to the respective computers 2 and 3 via computer interface devices 10 and 11 (this is called upstream).
.

However, due to this switching, simulated information similar to the external information input from the transmission control device 12 can be sent from the simulated signal generation computer 3 to the transmission system bus 13 on the performance test computer 2 side (this is called downstream). Become. In addition,
The computer interface device 10 converts external information into DMA
When writing to the area 6, the information in the DMA area 6 is compared with the newly transmitted external information, and if there is a state change in the external information, the performance test computer 2 is notified by an interrupt signal.

Obtain predefined equipment information from database 1. This equipment information includes type information and validity determination information of each data for the transmission information array. Data type information refers to control information in transmission, 0N10
This is information that indicates binary information indicating FF or numerical information such as analog data, and validity determination information also includes equipment information indicated by 6 or higher, which is upper and lower limit value information that indicates a steady range in numerical information. transmission information in a steady state is created. For example, in the case of binary information, a steady state pattern is set, and in the case of numerical information, it is set as an intermediate value between an upper limit value and a lower limit value. Furthermore, the numerical information is changed at regular intervals, or the state is changed to an abnormal state, thereby simulating a state change. In addition, for binary information, changes in status at the time of a system fault are simulated. The simulated signal generation computer 3 outputs the external information obtained as described above to the DMA area 7 provided in the local memory 5.

Next, the computer interface device 11 reads the information in the DMA area 7 via the DMA bus 9 at regular intervals, sends it to the transmission system bus 13, and transmits it to the computer interface device 10. Computer interface device 10

At this time, the computer interface device 10 compares the external information read from the transmission system bus 13 with the transmission information read from the DMA area 6 for the previous performance test computer 2, and if there is a change in the external information, the DM
The signal is transmitted to the performance calculator 2 via the A bus 8. The performance test computer 2 recognizes the change in the state of the power system based on the interrupt signal obtained in this way, reads external information in the DMA area 6 created in the local memory 4, identifies the state of the power system, and changes the state of the power system. Performance tests will be conducted by performing actual tasks such as monitoring.
