This invention relates to a measurement value simulation information generation method for generating measurement value information in a simulated manner.

[Technical background of the invention] External to a computer system, for example, a direct memory access device (DMA device) or a process input/output device (
When testing software on a computer system that inputs measured value information using a Pi10 device or a modem device and performs processing such as monitoring, recording, and controlling equipment status and measured values, it is necessary to input measured values for testing from an external source. This is a procedure for providing information in some way and checking the behavior of the software in response to this information.

[Problems with the Background Art] However, in the process of producing software, the DMA device, PI10 device, modem device, etc. that make up the electronic computer system may not be ready due to the production process, and measurement value information cannot be input. There was a problem in that it was difficult to arbitrarily generate the measurement value information necessary for Tests 1 to 1 because there was no device to be measured that was outside the manufacturing range.

Furthermore, even in confirmation tests after software modifications have been made after system operation, it is impossible to change measurement value information from actual operation for testing purposes, making it difficult to carry out sufficient confirmation tests.

[Object of the Invention] The present invention was made to solve the above problems, and an object thereof is to provide a measurement value simulation information generation method that can generate arbitrary measurement value information as necessary. It is said that

[Summary of the Invention] In the present invention, simulated measured value data is inputted by a measured value simulated information generating means from an operator via a man-machine device, and written into a measured value storage area using the data; The timing of writing to the measurement value storage area and the address of the measurement value storage area to be written are determined, and based on this, the predetermined simulated measurement value data is written to the predetermined measurement value storage area at a predetermined time, and then the software By transferring control to the processing program, it is intended to execute the same processing as when measurement value information is actually input.

[Embodiments of the Invention] The present invention will be described in detail below. FIG. 1 is an overall configuration block diagram showing an example of an electronic computer system incorporating a measurement value simulation information generating means according to the present invention. The remote monitoring and control device 1 is for transmitting measurement value information to a computer system 2, and the computer system 2 is connected to a DNA device 3 that inputs the measurement value information transmitted from the remote monitoring and control device 1. , an HA information storage area 4 on the main memory into which DMA information is processed and written, a measurement value monitoring program 10 and a measurement value simulation information generation means 11.
a central processing control unit 5 for storing data for the measured value simulation information generating means 11, a printing device 7 as a man-machine device, and a CRT input/output device (1).
8 and an external memory 6 used as an input/output data area for a CRT input/output device (2) 9.

- CRT input/output device (1) 8 is the measurement value monitoring program 1
CRT input/output device (2) for outputting the processing results of 0.
Reference numeral 9 is for setting data used when the measurement value simulation information generation means 11 executes.

FIG. 2 explains the configuration of the DMA information storage area 4. The units of information processed by the DNA device@3 are divided into channels determined by the number of remote monitoring and control devices 1, words forming the channels, and bits forming the words.

Corresponding to this configuration, the DNA information storage area 4 is composed of areas for each word and each bit for each channel type. The measurement value information transmitted from the remote monitoring and control device 1 is either binary data or numerical data, and correspondingly, 16
Each word of the bit configuration is either a binary data word 12 or
numeric data word 13. As shown in the figure, the binary data word 12 has 3 to 15 bits each having a meaning indicating an individual state. Numerical data word 13 represents one numerical value using 3 to 15 bits. Note that bits 0 to 2 are for transmission processing.

Next, in the above configuration, how the measured value simulation information generating means 11 according to the present invention operates will be explained.

In FIG. 1, measured value information is input to a DMA device 3 at regular intervals by a remote monitoring and control device 1.

The DMA device 3 writes the information to a predetermined DMA information storage area 4 on the main memory, and further interrupts the central processing controller 5 if the binary data has changed from the previous value to monitor the measured value. Start program 10.

The measured value monitoring program 10 is activated by this interruption, and in addition to inputting and monitoring binary data, it also runs at regular intervals to input and monitor numerical data. The measurement value monitoring program 10 not only performs monitoring, but also stores the monitoring results in the external memory 6 and prints them on the printing device 7 as necessary.
It has the function of outputting the information to the computer and displaying it on the CRT input/output device (1) 8 to notify the operator.

The method of generating measured value simulation information in place of the measured value information by the remote monitoring and control device 1 and the DMA device 3 is as follows.

First, the operator displays a previously prepared measurement value simulation information setting screen on the CRT input/output device (2) 9, and sets a request while talking to the CRT screen service program. The measurement value simulation information setting screen has functions that enable settings such as selection of channels, words, and bits, values to be given to them, and how to change the values over time. The set data is stored in the setting data file 30 shown in FIG. 3 from this screen. When the settings are completed and the operator instructs to start execution from the screen, the measured value/simulation information generating means 11 starts running, extracts the data from the setting data file 30, and proceeds with the process. This process is based on the flowchart shown in FIG.

The measurement fa simulation information generating means 11 first inputs setting data in a setting data input process 31, learns the channel, word, and bit from the data in the next DNA address calculation process 32, and stores the corresponding DNA information storage area. Calculate the address of 4.

Subsequently, in the DMA information generation process 33, the DMA device 3
generates data having the same shape as that written in the DMA information storage area 4. Then, a time designation determination process 34 and a delay process 35 perform synchronization until the specified time, and a DMA information storage process 36 loads the data generated in the above process into the DMA information storage area 4.

Further, in a pseudo-interrupt generation process 37, an interrupt is generated in the central performance control unit 5, and software control is transferred to the measurement value monitoring program 10. In this way, the input of one piece of information can be simulated), and by repeating this for all setting data in the completion check process 38, a system test is executed for the measurement value information transmitted from the remote monitoring and control device 1. to become)

As described above, according to this embodiment, the function of the computer system that inputs measured value information and monitors the status of equipment and monitors measured values is simplified without using the remote monitoring and control device 1 or the DMA device 3. It can be confirmed by a suitable method). By enhancing the functions of the measurement value simulation information setting screen, it is also possible to generate simulation information by setting system initial values or setting a specific pattern.

The present invention is not limited to this embodiment, and the following modifications are also possible.

(2) The method is not limited to the method of inputting measurement value information using the remote monitoring and control device 1 and the DMA device 3, and any information transmission device may be used. That is, if the input is via a modem device, the modem device reception data and the measurement value simulation information generation means 11 for the reception area may be used, and if the input is via the PI10 device, the PI10 device input data and input may be used. The measurement value simulation information generating means 11 for Canilia may be used.

■The simulation information generation setting data given to the measurement value simulation information generation means 11 does not require the preparation of a dedicated CRT input/output device (2) 9, and uses an input/output device prepared for other processing purposes. It's okay.

In the embodiment of FIG. 1, a CRT input/output device (1) 8 can be used. Furthermore, data can also be set using a card input device, floppy disk device, HT device, or the like.

(2) The program for inputting and processing measured value information has been described as the measured value monitoring program 10, but any number of programs for inputting and processing 31 measured value information may have any processing purpose.

[Effects of the Invention] As explained above, according to the measurement value simulation information generation method according to the present invention, the function of the system can be sufficiently confirmed without requiring the remote monitoring control device 1, the DMA device 3, or the process input device. can do.

Therefore, during system development, the remote monitoring control device 1, DMA device 3, or process input! There is no need for combination with i-devices or special test equipment, which is effective in shortening the system development period and reducing system development costs. Furthermore, since the simulated information setting data can be saved for many cases and used repeatedly, it can be applied to system response tests and load tests, which is also effective in improving quality.

Furthermore, in confirmation tests accompanying software modifications after system operation, there are many cases in which actual information cannot be easily input, but this problem can be solved by this measurement value simulation information generation method as described above.
