  In the configuration shown in FIG. 8, data indicating the equipment state of the monitoring control target equipment 100 is collected as follows.

  First, data indicating the state of the monitoring control target equipment 100 is collected by the data collection function of the monitoring control program 112 incorporated in the monitoring control computer 111 of the monitoring control system 110 and stored in the monitoring control computer 111. .

  When a screen call / screen operation signal is output by the screen automatic call program 133 incorporated in the analysis computer 131 of the equipment data analysis processing system 130, a keyboard / mouse signal is generated based on the screen call / screen operation signal. A keyboard / mouse operation signal for calling a screen is generated by the program 132 and transmitted to the keyboard / mouse signal transmission device 118 of the monitoring control system 110 via the network 120. The keyboard / mouse operation data is notified from the keyboard / mouse signal transmission device 118 to the supervisory control computer 111 via the signal synthesizer 116.

  FIG. 9 is a flowchart showing an outline of the operation of the facility data analysis processing system 130 shown in FIG. As shown in FIG. 9, various keyboard / mouse operation signals for calling a screen are sequentially transmitted from the equipment data analysis processing system 130 to the monitoring control system 110 (S11), and these keyboard / mouse The operation signal is sequentially notified to the monitoring control computer 111 of the monitoring control system 110, and a screen corresponding to the keyboard / mouse operation signal is displayed on the monitor device 114 by the monitoring control program 112 (S12).

  By the way, in the prior art shown in FIG. 8, in order to display a screen showing the equipment state on the monitor device 114 of the supervisory control system 110, the equipment data analysis processing system 130 outputs a keyboard / mouse operation signal for calling a screen. The information is generated and notified to the monitoring control computer 111 via the signal synthesizer 116 of the monitoring control system 110 through the network 120.

  When such a keyboard / mouse operation signal notification method is employed, all of the series of keyboard / mouse operation signals transmitted from the facility data analysis processing system 130 for calling a certain screen are displayed on the monitor device 114. It is a necessary condition that it is accurately reflected in all the screens displayed on the screen.

Here, the screen identification data storage unit displays a screen displayed on the monitor unit as a result of transmission of the operation signal by the operation signal generation unit, and a partial image characteristic to the screen of that type for each different type of screen. This is a portion in which reference image data expressed as a set of data is preliminarily stored with screen identification data that is combined with operation signal specifying data that specifies an operation signal from which a screen of the type is displayed. The image determination unit is actually displayed on the screen based on the screen identification data stored in the screen identification data storage unit each time the screen is displayed on the monitor unit as a result of operation signal transmission by the operation signal generation unit. This is a part for determining whether the image data of the determination target screen matches the reference image data of the operation signal. The operation signal generation unit is configured to continue the generation and transmission of the operation signal only when the determination result by the image determination unit is coincident, and to stop the generation and transmission of the operation signal when they do not coincide with each other. .

A storage unit) 201 and an image determination program (image determination unit) 202 are added.

  Here, the screen identification data file 201 is a screen displayed on the monitor device 114 of the monitoring control system 110 as a transmission result of the keyboard / mouse operation signal by the keyboard (KB) / mouse signal generation program (operation signal generation unit) 132. This is a data file in which the screen identification data indicating the characteristics of each is stored in advance for each different type of screen. The screen identification data file 201 is stored in various memories or storage devices of the analysis computer 131 in the same manner as the image data file 136 and the equipment data file 137.

  FIG. 2 is a diagram showing a data configuration of the screen identification data 210 stored in the screen identification data file 201. As shown in FIG. As shown in FIG. 2, the screen identification data 210 includes a name or number (screen type) 211 indicating the screen type and a set of partial image data characteristic of the screen for each different type of screen. The reference image data 212 to be expressed is combined with the operation signal specifying data 213 for specifying the operation signal from which the screen of the type is displayed.

  In this case, if there is a unique operation signal name such as a name or number that can individually identify the operation signal from which each type of screen is displayed, the unique operation signal name is designated as operation signal identification data. What is necessary is just to use as 213. On the other hand, the reference image data 212 is substantial data expressed as a set of partial image data, but a specific data configuration of the reference image data can be appropriately selected. For example, a unique reference image data name such as a name or number that can identify each reference image data is used, and a table that associates the reference image data name with the screen type and operation signal specifying data is managed. A substantive reference image data file to which the reference image data name is added may be managed separately.

  The image determination program 201 is stored in the screen identification data file 201 each time it is displayed on the monitor device 114 of the monitoring control system 110 as a transmission result of the keyboard / mouse operation signal by the keyboard / mouse signal generation program 132. Based on the screen identification data 210, it has a function of determining whether the image data of the determination target screen that is actually displayed on the screen matches the reference image data of the operation signal.

  Further, along with the addition of the image determination program 201, the keyboard / mouse signal generation program 132 of the present embodiment continues to generate and transmit the keyboard / mouse operation signal only when the determination result by the image determination program 201 matches. In the case of mismatch, it has a function of canceling generation and transmission of keyboard / mouse operation signals.

  Along with the addition of the image determination program 201, the image analysis program 135 of the present embodiment performs an image analysis process on the image data of the screen determined to match the screen only when the determination result by the image determination program 201 matches. If they do not match, the image analysis processing of the image data of the screen is not performed.

[Operation]
In the configuration of the present embodiment as described above, data indicating the equipment state of the monitoring control target equipment 100 is collected as follows. In this embodiment, the operation of the monitoring control system 110 is exactly the same as that of the conventional monitoring control system 110 shown in FIG. 8, and the operation of the equipment data analysis processing system 200 is basically the same as that shown in FIG. 8 is the same as the operation of the conventional facility data analysis processing system 130 shown in FIG. 8, and the following description focuses on characteristic operations that are different from the conventional one.

  FIG. 3 is a flowchart showing an outline of the operation of the equipment data analysis processing system 200 in the present embodiment. As shown in FIG. 3, various keyboard / mouse operation signals for calling a screen are sequentially transmitted from the equipment data analysis processing system 200 to the monitoring control system 110 (S11), and these keyboard / mouse The operation until the operation signal is sequentially notified to the monitoring control computer 111 of the monitoring control system 110 and the screen corresponding to the keyboard / mouse operation signal is displayed on the monitor device 114 (S12) is the same as the conventional operation. is there.

  Then, an image signal displayed on the monitor device 114 of the monitoring control system 110 is transferred to the analysis computer 131 of the equipment data analysis processing system 200 through the network 120 via the image signal distributor 113 and the image signal transmission device 115. The operation up to the transmission (S13), the image data capturing program 134 capturing the image data, and storing it in the image data file 136 (S14) is the same as the conventional one.

  In the equipment data analysis processing system 200 of this embodiment, the image determination program 202 performs image determination processing on the image data stored in the image data file 136 before performing image analysis processing by the image analysis program 135. It differs from the conventional one in the point (S21) to be performed. In this image determination process (S21), the image determination program 202 uses the screen identification data 210 stored in the screen identification data file 201 to determine that the image data of the determination target screen that is actually displayed on the screen is the operation signal. It is determined whether or not it matches the reference image data, and the determination result is notified to the automatic screen calling program 133 and the image analysis program 135.

  When the determination result is a screen match (YES in S22), that is, when a correct screen that should be displayed is displayed by the transmitted keyboard / mouse operation signal, the screen automatic call program 133 displays the screen call / screen. The output of the operation signal is continued, and the keyboard / mouse signal generation program 132 continues the generation / transmission of the keyboard / mouse operation signal (S23). In this case, the image analysis program 135 performs image analysis processing of the image data of the screen determined to match the screen, generates facility data in the character data format, and stores it in the facility data file 137 (S24).

  On the other hand, if the determination result is a screen mismatch (NO in S22), that is, the correct screen that should be displayed by the transmitted keyboard / mouse operation signal is not displayed, and an incorrect screen is displayed. If so, the screen automatic call program 133 stops outputting the screen call / screen operation signal, and the keyboard / mouse signal generation program 132 stops generating / transmitting the keyboard / mouse operation signal (S25). In this case, the image analysis program 135 stops the image analysis processing of the image data of the screen determined to be inconsistent with the screen (S26).

  By performing the characteristic processing (S21 to S26) as described above, an illegal screen that does not correspond to the keyboard / mouse operation signal transmitted from the equipment data analysis processing system 130 on the monitor device 114 of the monitoring control system 110. Is displayed, the illegal screen display can be easily confirmed by the image determination processing by the image determination program 202.

  When the screens do not match, the generation / transmission of the keyboard / mouse operation signal can be automatically stopped, so that the unauthorized screen display or the unauthorized screen operation on the monitor device 114 of the monitoring control system 110 is promptly stopped. can do. In addition, when the screens do not match, the image analysis processing of the image data of the screen is not performed, and there is no inconvenience such as generation and storage of the apologized equipment data from the illegal image data.

For the sake of convenience, the description of specific numerical values of the size of the color element component is omitted in the drawing.

  FIG. 7 is a flowchart showing an example of image determination processing (S21) by the image determination program 202 when the reference image data 212 shown in FIGS. 4 to 6 is used. As shown in FIG. 7, the image determination program 202 uses the image file of the reference image data 212 and the partial image table related to the transmitted keyboard / mouse operation signal, and uses the partial image table for each of the reference image data. A process of determining whether or not the size of the color element component for each pixel matches between the actually displayed image data of the determination target screen and the partial image data is performed on the coordinate range of the data.
