Description

DETAILED DESCRIPTION OF THE INVENTION (1) The present invention relates to a test method for a process operation system, and in particular to a test method for a process operation system suitable for centrally managing test data of process operation amounts by various devices under test that operate the process. Concerning test methods.

A system as shown in FIG. 1 has been used as a system for centrally managing test data of process operation amounts by various devices under test. The conventional system shown in FIG. 1 is a configuration diagram when various plants installed in nuclear power plants, thermal power plants, etc. are used as test equipment. The system shown in Figure 1 is equipped with a detector 4 at the plant measuring end 2 that detects the process operating amount of the plant, and a converter 6 converts the detection output detected by this detector into an electrical signal. , is supplied to a process personnel dispatch device 12 of a process computer system 10 via a signal line 8. The process computer system 10 includes a process computer 14. A t-pellator operation panel 16 is provided. The process computer 14 takes in the signals supplied from the process people evacuation device 12 in constant synchronization, and performs signal conversion processing using this signal and (2) conversion specifications predetermined according to the type of each detector 40. and calculate and process the operating amounts of processes by various plants.

However, such a calculation method does not allow comprehensive testing of the hole including the entire plant measuring end 2 and signal line 8.

Therefore, as shown in FIG. 1, a simulated signal generator 18 that generates simulated signals for instructing various plant test operations is provided on the plant measuring end 2 side, and the simulated signal from this simulated signal generator 18 is The system instructs test operations of various plants by using the indicator 20, reads the process operation amount of the plant due to the test operations, and uses the readings of the indicator 20 as test data. A method has been adopted in which both records are compared with actual operation data of process operation amounts of various plants based on commands from the process input/output device 12. Specifically, this is performed by the processing procedure shown in FIG.

That is, in step 100, a measurement terminal to be tested is determined on the plant measurement terminal z side, preparations are made to generate a simulated signal, and the measurement point to be tested is communicated to the computer system 10 (IIl).Next, as shown in step 102, the measurement terminal to be tested is determined on the computer system 10 side At this point, the operator operates the operator operation panel 16 to enable the recording of test data for the specified measurement point, and prepares to collect test data for the measurement point.When the preparation is complete, the data is placed on the plant measurement end 2 side. Next, the process moves to step 104 and the simulated signal generator 1
8 outputs a simulated signal and records the reading of the indicator 20.

After this, the computer system 10 is requested to collect test data. After this, the process moves to step 106 and test data as shown in Table 1 is recorded.

When the recording of the test data is completed in step 106, this is reported to the plant measurement end 2 side. Next, the process moves to step 108, and on the plant measurement end 2 side, it is determined whether or not tests on all plants have been completed.

If all the tests have not been completed in step 10B, the process moves to step 110, where the simulated signal generator 18 again generates a simulated signal corresponding to the plant that has not been tested, and the process moves to step 104 again.

On the other hand, if all the tests are completed in step 108, the process moves to step 112, and the test data read by the indicator 20 is compared with the test data processed on the process computer system 10 side. In addition, the test was conducted at the same measurement point in the range of 0 to 100 inches,
Verify data at each stage.

However, the test method using the above processing has the following drawbacks.

(1) Generally, the plant measurement terminal 2 and the computer system 10 that centrally manage it are located at a distant location (6) -, and when testing using the method described above, it is necessary to It is necessary to allocate test personnel to

(2) When conducting a test, it is necessary to maintain close communication between the plant measurement end 2 side and the computer system 10 side, and a communication means is required for these communications.

(3) Since test data is recorded by testers who continuously monitor the test data and record representative data, errors in reading and recording are likely to occur.

(4) Since the test data is sampled continuously, it is not possible to analyze a wide range of tests due to the noise characteristics of the signal line 8, etc.

The present invention has been made in view of the above-mentioned conventional problems,
The purpose is to provide a method for testing a process operating system that can automatically select various devices under test and record test data.

In order to achieve the above object, the present invention instructs various devices under test that perform process operation to perform process operations, calculates actual operation data of the amount of process operation by the various devices under test based on this command, and performs a process corresponding to the instructions. Test 1 A test method for a process operation system in which a test operation is commanded to the device under test, test data of a process operation amount by each device under test is calculated based on this command, and these calculated data are recorded. The present invention is characterized in that command information for instructing the order of operation and operation procedure for the test devices in a predetermined order is determined, and data calculation based on the operation of each device under test is executed in accordance with this command information.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 3 shows a configuration diagram of a process operation system according to a preferred embodiment of the present invention, in which various plants installed in a nuclear power plant or the like are used as test equipment, similar to FIG. 1. @ This embodiment includes an identification pattern signal generator 20 that generates an identification pattern signal as command information for instructing the plant measuring terminal 2 to operate the various plants in accordance with a predetermined order of operating order and operating procedure. This system differs from the conventional system in that a switch 22 is provided, and data calculation based on the operation of each plant is executed in accordance with this identification pattern signal.

The identification pattern signal generator 20 generates a pulse-like signal according to the effective range of the test measurement point of each plant, as shown in FIG. 4(b), and outputs it as an identification pattern signal. That is, this identification pattern signal is a pulse-like signal having a change characteristic to be clearly distinguished from the detection signal by the detector 4 or the simulated signal. Furthermore, this identification pattern signal is composed of a start signal indicating the operating order for selecting the measurement point of the plant to be tested, and a mode signal indicating the operating procedure for instructing the test method for the selected measurement point. There is. The change characteristics of the start signal and mode signal are defined as follows.

That is, as shown in FIG. 4(b), after the start signal A remains on for the period d shown in FIG. 4(a), it returns to the off state and continues in that state for the same period d. That is, the signal has a characteristic that the on and off states continue for the same period d.

Furthermore, the mode signal B shown in Φ) is composed of four elements, and the combination of these elements defines 16 types of operation procedures. The combination of components showing this operating procedure is shown below.

oooo: o Chi level signal applied 0001: 25 Chi level signal applied 0010: 50 Chi level signal applied 0011 Near 5 Chi level signal applied 0100: 100 Chi level signal applied 0101: Thermocouple characteristic test 1111: Preliminary The above identification pattern signal is a signal changeover switch. 22
is supplied to the computer system 10 via. Therefore,
The computer system 10 side also requires a function to detect the identification pattern signal.

In addition, in order to differentiate the identification pattern signal B from the start signal A, it is expressed as an analog quantity with the maximum effective range of the measurement points to be tested in various plants as the state on (C level 1), and the minimum effective range as the state off (level 0). There is a need to.

Therefore, when detecting the identification pattern signal B, it is necessary to capture the fluctuation of the analog quantity. That is, (b
), a dead band a1+bl may occur in the identification pattern signal B for the ON state and OFF state. Therefore, it is necessary to make sure that the state value does not change even if the level of the identification pattern signal B changes slightly ◎ Father, the information per component of the identification pattern signal B is (a
) is sequentially supplied to the computer system 10 every period d shown in FIG. However, the input operation on the side of the computer system 10 receiving the identification pattern signal B is performed at a prescribed sampling period, regardless of the signal output operation of the identification pattern signal generating device 20. Therefore, if the input operation on the computer system 10 side is 1 second, it will take at most 1 second to actually operate the identification pattern signal supplied from the identification pattern signal generator 20 on the process computer 10.
There will be a time delay of seconds. Furthermore, since the identification bar (11) turn signal is an analog quantity, there is a time delay until the actual signal level is established.

Therefore, in this embodiment, the state quantity of one component of the identification pattern signal is continuously generated for a certain period of time.
Computer systems also perform continuous sampling over a certain period of time, and out of various detected state values, state values that satisfy certain conditions are considered positive, allowing signals with high fluctuation factors to be processed without synchronizing with the signal source. A method of detection was used.

In other words, 1-1- A method is used to constantly monitor whether or not an input corresponding to the maximum effective range of the scanning point indicating the start signal of the identification pattern signal has occurred every time the analog signal is operated on the X i system 10 side. there was. Specifically, the computer 10 is supplied with an input signal corresponding to the maximum effective range.
In the process, the value of this input signal is continuously compared with a predetermined state determination value until the input of the identification pattern signal is completed. That is, in the computer system 10, the identification pattern signal shown in FIG. 4(b) is sampled at a period of 01 m C2 shown in FIG. It is grouped and stored as information on human power values.

In CC) and (e) of Fig. 4, the identification pattern signals of (1)) are sampled in the period CI+02, and these are in the on state (1), in changing state (X), and in the state off Co).
The classification into three values is shown, (d), (f
) shows the state value of one component in period d.

The grouped information obtained in this way is determined based on predetermined state identification conditions (for example, a state in which the same state value continues three or more times in a row is regarded as a positive state value in the group), Find the final state identification pattern.

When the identification pattern signal is detected on the computer system 10 side, test data is input from the plant measurement terminal 2, and this switching operation is performed by operating the signal switching switch 22. Therefore, after the identification pattern signal is detected, the computer system 10 stops collecting data for the test target point until the time period e shown in FIG. 4(a) has elapsed. Then, after the test data (13) is established, the collection of test record data is started.

The test data is sampled outside the predetermined number of times, and the collected data for each sampling, the average value according to the number of sampling times, the engineering conversion value calculated based on this average value,
The standard value of the relevant measurement point according to the type of test and the deviation between the collected data and the standard value are determined and stored for each measurement point to be tested in various plants. Then, after all tests are completed, the test results are output in the form of a report.

In the above embodiment, the identification pattern signal was sampled at different periods, but the state duration time (d) of one component of the identification pattern signal and the analog signal scanning period (period C) by the computer system
I 1 C2) If conditions for identifying the status of grouped information are appropriately determined, it is possible to detect identification butter/signals that occur regardless of the manual scanning and scanning period of the computer system.

In this way, according to this embodiment, by inputting the identification pattern signal from the plant measurement end side, the computer system (14) can automatically detect the test start time and test method, and also record the test data. This can also be done without the intervention of the examiner.

Further, in the above embodiment, the test method is instructed by a one-sided method of inputting the identification pattern signal from the plant measurement terminal, but an audio notification device is provided on the computer system side, and this device allows the paging device, etc. Even if the tester at the plant measurement end side recognizes the test object measurement point group, test type, test data, etc. 1 detected on the computer system side via the computer system side, the same effect as in the above embodiment can be obtained.

As explained above, according to the present invention, test operations on the computer system side can be remotely controlled by giving an identification pattern signal from the plant measurement end side to the computer system side, so that measurement point selection and test data can be controlled remotely. It has the excellent effect of automatically recording data.
