For the numerical variable image 22 (numerical value X), it is confirmed whether the drawing is performed in a desired display color by changing the value of the assigned analog signal.

  FIG. 6 is a configuration example of monitoring screen information in the monitoring screen test apparatus. The monitoring screen information stored in the monitoring screen information storage device 1 includes a monitoring screen information ID for identifying the monitoring screen information and a plurality of variable image information. The variable image information includes additional information such as a variable image ID for identifying a variable image, a display position, names of a plurality of signals allocated to the variable image, and variable image change conditions.

T stored in the test item storage device 6 includes a test item ID for identifying the test item T, a monitoring screen information ID of a monitoring screen to be tested, a display position and size of a variable image, and a value for which signal. It consists of signal generation information on whether to set and correct image information when the test is successful. Correct image information is represented by an image pattern ID and a display state ID.

  FIG. 11 shows an example of test items in the monitoring screen test apparatus. FIG. 11A is a specific example of the test items for the valve A and the valve B, and FIG. 11B is a specific example of the test item for temperature values. The test items in FIG. 11 are for the monitoring screen 100 (S001) in FIG. The test item T1 whose test item ID is T1 is for testing the valve A. When all the digital signals DI001, DI002, and DI003 are set to OFF values, the image pattern is “valve” and the display state is “closed”. ”Is displayed, the test is defined to be correct. Hereinafter, the test item whose test item ID is T1 is referred to as test item T1. The test item T3 is for testing the valve B. If all the digital signals DI011, DI012, and DI013 are set to OFF values, the image pattern is “valve” and the display state is “closed”. It is defined that the test is correct. Since there are eight combinations of the values of the three digital signals, eight test items T for the variable images of the valve A and the valve B can be considered.

  In the case of a variable image to which an analog signal such as a numerical value X is assigned, it is not possible to test all values, so a value between the boundaries and a value between the boundaries are tested. In the variable image of temperature, there can be considered at least five types of test items T: a value exceeding the upper limit, an upper limit value, a normal value, a lower limit value, and a value exceeding the lower limit. In the test item T2 of FIG. 11B, it is defined that the test is correct if the analog signal AI001 is set to 30.000 and the image pattern is in the “normal” display state of “temperature numerical value”.

  FIG. 12 is a configuration example of test results in the monitoring screen test apparatus. The test result R stored in the test result storage device 8 includes a test item ID, a test result R indicating success / failure, and additional information which is image information when the test fails.

  A specific test execution example will be described using the test items in FIG. 11 as an example. First, the test item T1 will be described. As shown in the flowchart of FIG. 2, the automatic test execution means 9 takes out the test item T1 from the test item storage device 6 (step S1). Next, the monitor screen information ID (S001) is sent to the monitor screen generating means 2, and the signal generation information 1 to 3 is sent to the simulated data generating means 4. The simulation data generation means 4 generates a value that simulates the signal and gives it to the monitoring screen generation means 2 (step S2). The monitoring screen generating means 2 takes out the monitoring screen information from the monitoring screen information storage device 1 and generates a test monitoring screen by changing the variable image based on the value simulating the signal given from the simulated data generating means 4. And stored in the image storage device 3 (step S3). The generated monitoring screen is as shown in FIG.

  FIG. 13 is an example of a monitoring screen generated based on the test items of the monitoring screen test apparatus. FIG. 13A is a screen display 101 of the monitoring screen S001 generated based on the test item T1 for the valve A by the monitoring screen generation means 2, and FIG. It is the screen display 102 of the monitoring screen S001 generated based on the test item T2. A test example of the test item T2 corresponding to FIG. 13B will be described later.

  In FIG. 13A, the test target image G1 coincides with the display information image (image icon 15b in display state 2 shown in FIG. 9A) of “closed” of “valve” which is correct image information. Therefore, the image determination means 7 compares the image G1 to be tested with the display state of the image pattern stored in the image pattern storage device 5 associated with the correct image information of the test item T1, and determines the test item T1. It determines with success (step S4). The image determination means 7 transmits the result of the test item T1 to the automatic test execution means 9, and the automatic test execution means 9 stores the received result of the test item T1 in the test result storage device 8 (step S5).

  The automatic test execution means 9 determines whether or not the next test item T exists in the test item storage device 6 (step S6). Since the test item T2 exists, the processing from step S1 to step S5 is repeated. Next, the test item T2 will be described.

  The automatic test execution means 9 takes out the test item T2 from the test item storage device 6 (step S1). Next, the monitoring screen information ID (S001) is sent to the monitoring screen generation means 2, and the signal generation information 1 is sent to the simulated data generation means 4. The simulation data generation means 4 generates a value that simulates the signal and gives it to the monitoring screen generation means 2 (step S2). The monitoring screen generating means 2 takes out the monitoring screen information from the monitoring screen information storage device 1 and generates a test monitoring screen by changing the variable image based on the value simulating the signal given from the simulated data generating means 4. And stored in the image storage device 3 (step S3). The generated monitoring screen is as shown in FIG.

  In FIG. 13B, the temperature value of the image G2 to be tested is 30.000, and the character color is white. The test target image G2 matches the character color of the “normal” display information of the “temperature value” which is the correct image information (the character color of the display state 2 shown in FIG. 9B is white). Therefore, the image determination unit 7 compares the test target image G2 with the display state of the correct image information, and determines that the test item T2 is successful (step S4). The image determination means 7 transmits the result of the test item T2 to the automatic test execution means 9, and the automatic test execution means 9 stores the received result of the test item T2 in the test result storage device 8 (step S5).

  The automatic test execution means 9 determines whether or not the next test item T exists in the test item storage device 6 (step S6). Since the test item T3 exists, the processing from step S1 to step S5 is repeated. Test item T3 is similar to test item T1, and description thereof will not be repeated. After the test item T3 is completed, the automatic test execution means 9 determines whether or not the next test item T exists in the test item storage device 6 (step S6). If no other test item T exists, the process is performed. finish.

  As described above, the automatic test execution means 9 executes the automatic test by repeating the process for all the test items T stored in the test item storage device.

  The monitoring screen test apparatus 50 according to the first embodiment is able to discriminate a variable image that changes in accordance with the value of the signal from the plant by image processing by providing the image determination means 7. Therefore, unlike the conventional mistakes caused by the visual check by the person in charge of the test and the mistakes in the test due to the oversight, it is possible to prevent the erroneous mistakes due to the visual check by the person in charge of the test and the mistakes in the test due to the oversight. Since it is possible to prevent mistakes and oversights due to visual confirmation, it is possible to accurately test the monitoring screen. Moreover, the monitoring screen test apparatus 50 can automatically execute the test without the manual operation by providing the automatic test execution means 9. Test time can be shortened by automating the test by the automatic test execution means 9.

  Since the monitoring screen test device 50 includes the image pattern storage device 5, the correct image information of the test item T can be simplified and the data amount can be reduced.

  As described above, according to the monitoring screen test apparatus 50 of the first embodiment, the display of the variable images 20, 21, and 22 is changed based on the monitoring screen information in the test item T and the signal simulating the signal input from the plant. The monitoring screen generation unit 2 that generates the test monitoring screens 101 and 102, and the variable images 20, 21, and 22 of the test monitoring screens 101 and 102 generated by the monitoring screen generation unit 2 are the target variable images in the test item T. Since the image determination means 7 for determining whether the image information matches the correct image information is provided, it is possible to perform an accurate monitoring screen test that prevents mistakes and oversights caused by visual confirmation of the person in charge of the test.

  As the correct image information, the display position and size may be acquired from the electronic data of the specification created by the specification creation device of the monitoring screen. By creating the correct image information from the electronic data of the specifications, the correct image information can be created efficiently and accurately. Thereby, the test preparation time of the monitoring screen test apparatus 50 can be shortened, and the total test time including the preparation (test process) can be shortened.

Embodiment 2. FIG.
In the first embodiment, the example of automatically executing the monitoring screen test has been described. However, the correction of the monitoring screen information can be performed by guessing the error location of the monitoring screen information on the monitoring screen that failed the test and presenting the correction plan. It is possible to reduce the time and labor required for retesting. This will be described below.

  FIG. 14 shows a monitoring screen test apparatus according to Embodiment 2 of the present invention. The monitoring screen test apparatus 51 of the second embodiment is different from the monitoring screen test apparatus 50 of the first embodiment in that the monitoring screen information correction means 10, the estimation result storage apparatus 11, the correction plan estimation means 12, and the phenomenon information storage apparatus 13 are different. It is different in having. The monitoring screen information correction means 10 takes out the monitoring screen information from the monitoring screen information storage device 1 and corrects the monitoring screen information in response to the correction request. The estimation result storage device 11 stores the estimation result of the monitoring screen information correction proposal. The correction plan inference means 12 takes out the test result R and the test item T from the test result storage device 8 and the test item storage device 6 respectively, and estimates the error location and the correction candidate of the monitoring screen information. After the retest is executed using the automatic test execution means 10 with the monitoring screen information corrected by use, the estimation result is stored in the estimation result storage device 11. The phenomenon information storage device 13 stores a phenomenon when the test fails and a method for correcting the monitoring screen.

  In the second embodiment, the test result storage device 8 stores image information at the time of the correct answer as additional information regardless of whether the test result R is successful or unsuccessful. The monitoring screen information storage device 1 also stores corrected monitoring screen information.

  The monitoring screen information correction means 10 takes out the monitoring screen information from the monitoring screen information storage device 1 and corrects and saves the monitoring screen information based on the correction plan estimated by the correction plan estimation means 12.

  The estimation result storage device 11 stores information on whether or not there is a correction plan for the monitoring screen information for the failed test item T and, if present, the ID of the monitoring screen information for the correction plan.

  The revision suggestion means 12 extracts the test result R and the test item T that have failed in the test, and the related test result R and the test item T from the test result storage device 8 and the test item storage device 6, respectively. Based on the image information when the test result R is correct and when it fails, and the signal information of the test item T, the error location and the correction plan of the variable image description of the monitoring screen information are estimated. If there is a correction candidate, the monitoring screen information correction means 10 is used to correct the monitoring screen information, and the automatic test execution means 9 is used to execute a retest. The test item T that has failed and all the test items T including the ID of the corrected monitoring screen information are retested to confirm the correctness of the correction plan, and the result is stored in the guess result storage device 11.

  The phenomenon information storage device 13 stores the phenomenon information and the monitoring screen correction method when the test fails. The correction method of the phenomenon information and the monitoring screen is read by the correction plan inference unit 12. Here, the phenomenon information includes “phenomenon ID”, “failure phenomenon”, and “monitoring screen correction method”. Specific examples of the phenomenon information will be described later.

The operation of the correction plan inference unit 12 will be described with reference to the flowchart of FIG. FIG.
5 is a flowchart showing an execution procedure of a correction plan estimation process in the monitoring screen test apparatus 51. After all the tests are completed based on the flowchart of FIG. 2, the procedure of FIG. 15 is executed. First, the revision suggestion means 12 extracts the test result R from the test result storage device 8 (step S7). It is determined whether the test result R is a failure. If the test result R is unsuccessful, a correction plan estimation process from step S9 to step S19 is performed. The correction plan estimation process will be described later. If the test result R is successful, the process skips to step S20 (step S8). When the test result R is successful or when the correction plan estimation process (step S19 to step S19) in the case of failure ends, the correction plan estimation means 12 determines whether the next test result R exists in the test result storage device 8. It is determined whether or not (step S20), and if it exists, the process returns to step S7 to repeat the process. If it does not exist, the process ends.

  Next, the correction plan estimation process (step S9 to step S19) will be described. The correction plan inference means 12 determines whether an existing correction plan that is a correction plan for the target variable image of the test item T already exists by the correction plan estimation process for the other test item T previously performed in the estimation result storage device 11. Determine if. If there is already an existing correction plan for this test item T by the correction plan estimation process for another test item T previously performed in the estimation result storage device 11, the process skips to step S20 (step S9). If not, the failed test item T is taken out from the test item storage device 6 (step S10).

  Subsequently, the correction plan inference means 12 takes out the related test result R and test item T from the test result storage device 8 and the test item storage device 6, respectively (step S11). Based on the extracted test result R, the correct and unsuccessful image information of the test result R in the test item T, and the signal information of the test item T, the error location and correction of the variable image description in the monitoring screen information A plan is guessed (step S12). Specifically, the correction plan inference unit 12 reads the phenomenon information stored in the phenomenon information storage device 13, confirms whether the failed test result corresponds to the registered phenomenon, and estimates the correction plan. To do.

  It is determined whether or not a correction candidate exists in the phenomenon information storage device 13 (step S13). If there is no correction candidate, the correction proposal estimation process is terminated, and the process proceeds to step S19. If there is a correction candidate, the monitoring screen information correction means 11 is instructed to correct the monitoring screen information according to the corresponding monitoring screen correction method stored in the phenomenon information storage device 13 (step S14). Based on the corrected monitoring screen information, the automatic test execution means 9 is used to retest the failed test item T (step S15).

  In the retest, processing similar to the operation from step S2 to step S4 in the flowchart of FIG. 2 is executed to determine whether the retest is successful. If the retest fails, the process returns to step S13, and if successful, the process proceeds to the next step (step S16). In step S17, the test item T having the same monitoring screen information ID as the corrected monitoring screen information is extracted from the test item storage device 6, and the retest is performed with the corrected monitoring screen information (step S17). It is determined whether or not the test is successful for all test items T. If the test result R is the same as the previous execution result, or if the test item T that has failed has changed to success, the correctness of the correction plan can be confirmed. Conversely, if the previously successful test item T has changed to failure, the correction plan affects other test items T, so the correction plan is not adopted and the process returns to step S13 (step S18). If the correctness of the correction plan can be confirmed, the fact that there is a correction plan is stored in the estimation result storage device 11. If the correctness cannot be confirmed or there is no correction candidate, the fact that there is no correction proposal is stored in the estimation result storage device 11 (step S19).

  FIG. 16 is an example of the estimation result in the monitoring screen test apparatus. The estimation result stored in the estimation result storage means 11 includes a test item ID, information on the presence / absence of a correction plan, and, if there is a correction plan, an ID of monitoring screen information of the correction plan.

  A specific monitoring screen example will be described. This is a case where the monitoring screen includes a variable image representing the state of the tank. FIG. 17 is an example of a variable image in the monitoring screen test apparatus. As shown in FIG. 17, a variable image representing a tank determines an image icon to be displayed by a combination of two digital signals. In the example, when the digital signal 1 indicating the low water level is ON, the image icon 15c indicating the low water level, when the digital signal 2 indicating the high water level is ON, the image icon 15d indicating the high water level, both of the digital signals are OFF. In this case, an image icon 15e indicating normality is displayed. The image pattern of the variable image of the tank at this time is shown in FIG. FIG. 18 is an example of an image pattern in the monitoring screen test apparatus. In the image pattern of the variable image of the tank water level, image icons 15c, 15d, and 15e are registered in each of the cases where the water level is low, the water level is high, and the water level is normal.

  In the monitoring screen including the tank described above, the specification is such that the signal TANK1-L is assigned to the digital signal 1 representing the low water level and the signal TANK1-H is assigned to the digital signal 2 representing the high water level. In this case, as the test item T, three tests T13 to T15 shown in FIG. 19 are assumed based on the signal specifications. FIG. 19 shows an example of a first test item in the monitoring screen test apparatus. In the example of FIG. 19, only a combination of signal generation information and correct image information is shown.

  Consider a case where the monitoring screen to be tested is assigned in reverse by mistake of the signal TANK1-L and the signal TANK1-H when the monitoring screen creator creates the monitoring screen information. In this case, as a result of executing the test, the test items T13 and T14 fail, and T15 succeeds. As shown in FIG. 20, the test results shown in R13 to R15 are stored in the test result storage device 8. FIG. 20 is an example of a first test result in the monitoring screen test apparatus. Test result R13 is the test result of test item T13, test result R14 is the test result of test item T14, and test result R15 is the test result of test item T15. At this time, the additional information of the test result R stores an image at the time of failure and a successful image that should be obtained if it succeeds.

  When the test is completed, the correction plan inference means 12 takes out the test result R13 (step S7). The correction plan inference means 12 reads the test result R13, determines that the test has failed (step S8), and corrects the test item T13 by the correction plan estimation process for other test items T previously performed in the estimation result storage device 11. It is determined whether there is a plan (step S9). Since there is no correction plan in the estimation result storage device 11, it is determined that there is no correction plan, and the process proceeds to step S10. The correction plan inference means 12 takes out the test item T13 which is the target of the test result R13 (step S10). As the test item T related to the test result R13, the test items T14 and T15 having the same monitoring screen information ID and the same signal information and the test results R14 and R15 are taken out (step S11).

  The revision suggestion means 12 executes step 12. The correction plan estimation means 12 reads the phenomenon information stored in the phenomenon information storage device 13 and confirms whether or not the result of the failed test corresponds to the registered phenomenon. FIG. 21 is an example of the phenomenon information stored in the phenomenon information storage device 13. The phenomenon information includes a phenomenon ID, a failure phenomenon, and a phenomenon screen correction method. The failure phenomenon confirmation method and the phenomenon screen correction method can be realized by executing a program by a computer. The phenomenon ID is phenomenon information of the example of the tank, and the phenomenon ID of phenomenon 2 is the phenomenon information of the example of the variable image of the temperature value described later.

The correction proposal inference means 12 is an image when the combination of the T13 signal and value is R14 and the combination of the T14 signal and value is an image when the correct answer is R13. Since it is reversed between R13 and R14, it is determined that it corresponds to phenomenon 1 in the phenomenon information of the phenomenon information storage device 13, and the variable image signal is assigned in reverse according to the phenomenon screen correction method of phenomenon 1. I guess that. Then, as a correction plan, an assignment obtained by inverting the signal TANK1-L and the signal TANK1-H of the variable image TANK1 is set as a candidate for a correction plan for the monitoring screen information.

  The correction plan inference means 12 determines that there is a candidate for the correction plan of the monitoring screen information (step S13), and instructs the monitoring screen information correction unit 10 to correct the monitoring screen information as the correction plan candidate. The monitoring screen information correcting unit 10 corrects the monitoring screen information in response to the correction request, and stores the corrected monitoring screen information in the monitoring screen information storage device 1 with another ID (step S14). The correction plan estimation means 12 uses the automatic test execution means 9 to execute a retest with the corrected monitoring screen information (step S15). In this example, the test of T13 succeeds by retesting. The revision suggestion means 12 determines that the retest of T13 has succeeded (step S16), and executes the retest on the other test items T having the same monitoring screen information ID (step S17). This includes the T14 and T15 tests, each successful. The revision suggestion means 12 determines that the other test item T having the same monitoring screen information ID has succeeded (step S18). Since the correctness of the correction plan has been confirmed, the correction plan estimation means 12 stores the estimation results for the test results R13 and R14 of T13 and T14 in the estimation result storage device 11 (step S19).

  As a second example, a description will be given of estimation of a correction plan on a monitoring screen including a variable temperature value image. In this monitoring screen, let us consider a case where the upper limit value is wrongly set as the additional information of the variable image of the monitoring screen information and a value higher than the original upper limit value is set. For example, in the example of the monitoring screen shown in FIG. 3, it is assumed that the upper limit value 80.0 of the additional information of the numerical value X in the variable image information 3 shown in FIG. In this case, as the test item T, four tests T16 to T19 shown in FIG. 22 are assumed. FIG. 22 is an example of a second test item in the monitoring screen test apparatus. In the example of FIG. 19, only a combination of signal generation information and correct image information is shown.

  In this case, as a result of executing the test, T17 and T18 among the test items from T16 to T19 shown in FIG. 22 fail. As shown in FIG. 23, the test results shown in R16 to R19 are stored in the test result storage device 8. FIG. 23 is an example of a second test result in the monitoring screen test apparatus. Based on these results, the correction plan inference means 12 reads out the phenomenon information stored in the phenomenon information storage device 13 in the procedure of step 12, determines that it corresponds to phenomenon 2 in the phenomenon information, and follows the phenomenon screen correction method of phenomenon 2. It is estimated that the description of the upper limit value is wrong and the upper limit value is between 75.0 and 90.0. By listing several candidates for the upper limit value, correcting the monitoring screen information using them as candidates for a correction plan, and performing a retest, the upper limit value can be specified. When the upper limit candidate is estimated to be 80.0, both the test items T17 and T18 succeed. Therefore, the correction plan inference means 12 determines that the other test items T having the same monitoring screen information ID have succeeded (step S18). Since the correctness of the correction plan has been confirmed, the correction plan estimation means 12 stores the estimation results for the test results R17 and R18 of T17 and T18 in the estimation result storage device 11 (step S19).

  As a third example, let us consider a case where an incorrect signal that cannot be estimated at all is assigned to a variable image on a certain monitoring screen. In this case, since the candidate for the correction plan cannot be estimated from the related test result R and test item T, the estimation result storage device 11 stores the result without the correction plan (step S19).

The monitoring screen test apparatus 51 according to the second embodiment is provided with the monitoring screen information correction unit 10 and the correction plan estimation unit 12, so that the failed test result R and the test item T, and the related test item T and the test result. From R, it is possible to infer the error portion of the monitoring screen information and the correction plan, and perform a retest to confirm the correctness of the correction plan. For this reason, it is possible to reduce the labor involved in correcting the monitoring screen information and the labor of retesting.

  Since the monitoring screen test apparatus 51 includes the phenomenon information storage device 13, it is possible to perform an estimation operation of an error location and a correction plan in the monitoring screen information in a short time. Further, since the monitoring screen test apparatus 51 has the estimation result storage apparatus 11 for storing the information on whether or not there is a correction plan of the monitoring screen information and the estimation result including the correction plan when there is a correction plan, the failed test item T The existing revision plan that is a revision plan for the target variable image can be used, and the revision plan estimation process for all the test items T on the monitoring screen can be executed in a short time.

  The monitoring screen test apparatus according to the present invention can test a monitoring screen that displays the state of the plant and the state of other devices, and can be suitably used for a monitoring control system that performs monitoring control of the plant.
