Description

  Embodiments described herein relate generally to an update test apparatus, an update test method, and an update test program for plant equipment.

  The plant monitoring and control system controls a plant using various facilities in the plant such as a power plant and a steel plant as control elements. As components of such a plant monitoring control system, there are various plant devices such as a control device and a computer.

  By the way, the stoppage of the plant has a large influence on the outside, and the cost is very high. For this reason, the plant has a high necessity of continuing operation for a long time. And the update of the apparatus which comprises a plant monitoring control system affects the continuous operation of a plant, and cannot be performed frequently. For this reason, the usage period of the plant apparatus is also very long. For example, the same device needs to be used continuously for at least 15 years.

  However, when the plant device becomes obsolete, it is necessary to stop the plant and update the currently used plant device to a new plant device. At this time, it is essential to accurately transplant functions from the device before update to the device for update. In the following description, the plant device before update is the old device, and the plant device for update is the new device.

  As a method of verifying the transplantation of functions, there is a method of performing verification at a site where an old device that actually monitors and controls the plant is installed. This is a method of confirming whether an equivalent result can be obtained by supplying the same input to both the new apparatus and the old apparatus using additional hardware such as wiring. It is also necessary to perform a combination test between a new device to be updated and a device not to be updated.

JP 2006-234696 A JP 2001-265403 A

  As described above, the plant needs to be operated continuously for a long time. For this reason, it is desirable that the period during which operation is stopped for renewal is as short as possible. In particular, recent thermal power plants have a strong need for shortening the suspension period for renewal from the viewpoints of stable power supply, cost reduction, effective use of facilities, and the like.

  However, as described above, when verification of function transplantation is performed on site, there is a possibility that incompatibility may occur such that the new device does not perform the same operation as the old device. In this case, it is necessary to repair the new equipment locally. Then, the stoppage period of the plant for renewal will increase.

  In order to cope with this, it is necessary to shorten the on-site system update period by sufficiently confirming the operation of the new device at the factory where the hardware and software of the new device are assembled.

  However, it is difficult to verify the operation in the factory with an apparatus equivalent to that installed at the site. As described above, this is because the renewal period of the plant equipment is very long.

  In other words, when it is time to renew after starting to use the plant equipment, the hardware corresponding to the old equipment may not be stored in the factory, or it may be outdated and cannot be used as it is. . In this case, the same system cannot be constructed in the factory, and the same verification as the local site cannot be performed.

  Embodiment of this invention provides the technique which can shorten the update period in a field by verifying in a factory whether the operation of a new device and an old device is equivalent in the update of the device for plants. For the purpose.

  In order to achieve the above object, an update test apparatus for a plant apparatus according to an embodiment has the following configuration.

(1) Of the plant equipment used for plant monitoring and control, the old equipment section simulating the plant equipment before the update
(2) Among the plant equipment, a new equipment section that simulates a plant equipment for updating

The old device section has the following configuration.
(3) The first control logic unit that executes calculations based on the control logic of the plant equipment before update
(4) A first input / output data storage unit that stores input data input to the first control logic unit and output data that is a calculation result of the first control logic unit based on the input data.

The new device section has the following configuration.
(5) A second control logic unit that executes calculations based on the control logic of the plant equipment for update
(6) A second input / output data storage unit that stores input data input to the second control logic unit and output data that is a calculation result of the second control logic unit based on the input data

  In addition, as another aspect, it can also be grasped as a method for realizing the processing of each unit by a computer and a program to be executed by the computer.

[1-2. Update test equipment]
The update test apparatus 1 includes an old device unit 11, a new device unit 12, a switching unit 15, and a comparison unit 16. The old device unit 11 is a control program that performs a simulation of data input / output processing and arithmetic processing in the old device.

  This control program is basically a copy of the control program of the old device. However, there are cases where the current update test apparatus 1 cannot be executed as it is, for example, when the program language is old or when the corresponding OS is old. For this reason, the old apparatus unit 11 also includes an emulator unit that causes the update test apparatus 1 to execute the control program of the old apparatus.

  The new device unit 12 is a control program in the new device. This control program basically includes the same control logic as the control program of the old apparatus. However, since the new control program is applied to the new apparatus, the program language, the program structure, the corresponding OS, etc. are often different from the control program of the old apparatus. For example, the display interface or the like may be expanded or improved as compared with the control program of the old apparatus.

  Even if the control program is executed in the actual new apparatus, the update test apparatus 1 may not be executed as it is. In this case, the new apparatus unit 12 includes an emulator unit that causes the update test apparatus 1 to execute a control program for the new apparatus.

  The old device unit 11 and the new device unit 12 include a part realized by hardware in the old device and the new device. Details of configuration examples of the old device unit 11 and the new device unit 12 will be described later. The switching unit 15 is a processing unit that switches whether the computer 2 described later is connected to the old device unit 11 or the new device unit 12.

  The determination unit 16 a is a processing unit that determines whether there is a difference between the calculation result of the old device unit 11 and the calculation result of the new device unit 12. The input / output unit 16b is a processing unit that receives calculation results from the old device unit 11 and the new device unit 12 and outputs a determination result by the determination unit 16a. The storage unit 16c is a processing unit that stores calculation results and determination results.

[1-3. calculator]
The computer 2 is a device for monitoring the plant. A display device 21 and an input device 22 are connected to the computer 2. The display device 21 is a device that informs an operator of information necessary for an update test, such as a plant status and a process status, by displaying a graphic screen, a message, and the like. The input device 22 is a device in which an operator who views the display screen of the display device 21 inputs information necessary for an update test, such as a call for information and an operation instruction. Note that the computer 2 is the same as that installed locally. For example, in the case of the computer 2 whose time has not passed since the last update, the same product as the local is stored in the factory and can be used.

[1-4. Simulator section]
The simulator unit 3 is a processing unit that simulates plant input / output data. The simulator unit 3 includes a storage unit 31, a generation unit 32, and an input / output unit 33.

The old device unit 11 and the new device unit 12 include interface units 11a and 12a, input / output data storage units 11b and 12b, table storage units 11c and 12c, control logic units 11d and 12d, input units 11e and 12e, output unit 11f, 12f.

  The interface units 11a and 12a are interfaces that control reception of input data generated by the simulator unit 3 in a simulated manner and transmission of output data that is a calculation result in the old device unit 11 and the new device unit 12.

  The input / output data storage unit 11b (first input / output data storage unit) and the input / output data storage unit 12b (second input / output data storage unit) are processing units that store input data and output data. The table storage units 11c and 12c are processing units that store table formats for the input / output data storage units 11b and 12b to store input data and output data.

  The control logic unit 11d (first control logic unit) is a processing unit that performs arithmetic processing on input data according to the control logic of the control program of the old apparatus, and outputs a calculation result as output data. The control logic unit 12d (second control logic unit) is a processing unit that performs arithmetic processing on input data and outputs output data by the control logic of the control program of the new apparatus. As described above, the control logic unit 11d of the old device unit 11 and the control logic unit 12d of the new device unit 12 are basically the same.

  The input units 11e and 12e are processing units that input input data received by the interface units 11a and 12a to the input / output data storage units 11b and 12b. The output units 11f and 12f are processing units that output the output data stored in the input / output data storage units 11b and 12b to the switching unit 15, the comparison unit 16, and the interface units 11a and 12a.

[1-6. Plant and old equipment]
Further, for comparison with the old device unit 11 and the new device unit 12, the local plant 4 and the old device 50 installed in the site will be described with reference to FIG. First, the plant 4 includes detectors A1 and A2 and control target devices X1 and X2.

  The old device 50 includes an input / output terminal block 51, an input / output control unit 52, an input / output data storage unit 53, a control logic unit 54, an input unit 55, and an output unit 56.

  The input / output terminal block 51 is a terminal block connected to the detectors A1 and A2 and the control target devices X1 and X2 of the plant 4 via cables. Terminal numbers TI1, ТI2, ТO1, and ТO2 of the input / output terminal block 51 correspond to the detectors A1 and A2 and the control target devices X1 and X2 of the plant A, respectively. The input / output control unit 52 is a processing unit that controls transmission / reception of data to / from the detectors A1 and A2 and the control target devices X1 and X2 via the input / output terminal block 51.

The output unit 56 is a processing unit that outputs the output data stored in the input / output data storage unit 53 to the input / output control unit 52.

[2. Action]
[2-1. Control of plant with old equipment]
First, the example of control of the plant 4 by the old apparatus 50 is demonstrated. The input / output control unit 52 receives the input data output from the detectors A 1 and A 2 via the input / output terminal block 51. The input unit 55 inputs the input data received by the input / output control unit 52 to the input / output data storage unit 53.

  The input / output data storage unit 53 stores input data in a table format. FIG. 5 is an example of an input / output data table in the input / output data storage unit 53. In FIG. 5, the input / output point number is information for identifying the detector and the control target device.

  The device number is information indicating the storage position of the input / output data in the old device 50. This device number is, for example, a storage area address. The terminal number is information for identifying the terminal of the input / output terminal block 51. In the value column of FIG. 5, the current input value indicated by the input data and the current output value indicated by the output data are stored.

  For example, since the detector A1 is connected to the terminal number TI1 of the input / output terminal block 51, the input / output data storage unit 53 stores the input data from the detector A1 as the row value of the device number I0001. In addition, the control logic unit 54 performs an operation according to the value stored in the input / output data storage unit 53. The output data which is the calculation result is stored in the input / output data storage unit 53.

  For example, the input / output data storage unit 53 stores the value of the operation result as the value of the row of the control target device X1 and the device number O0001 in the table. The output unit 56 outputs the value of the row of the control target device X1 in the input / output data storage unit 53 to the terminal number TO1 defined in the table via the input / output control unit 52 as output data.

[2-2. Update test]
Next, the procedure of the test process by the update test apparatus 1 will be described with reference to the flowchart of FIG. This is a process of operating the old device 50 and the new device in a virtual environment and comparing the results.

  First, the switching unit 15 connects the old device unit 11 to the computer 2. The interface unit 11a of the old apparatus unit 11 waits for input data that simulates an input / output point of the plant 4 (NO in step S01). The generation unit 32 of the simulator unit 3 generates input data that simulates the input / output points of the plant 4. The input / output unit 33 of the simulator unit 3 transmits input data to the old device unit 11 via the network N.

  The interface unit 11a of the old device unit 11 receives the input data via the network N (YES in step S01). The input unit 11e inputs input data to the input / output data storage unit 11b (step S02). The input / output data storage unit 11b stores the input data according to the table format stored in the table storage unit 11c (step S03).

  An example of the items in this table is shown in FIG. In FIG. 6, the device number and the terminal number are the same as those in FIG. The simulator input point number in FIG. 6 corresponds to the input point number in FIG.

  The control logic unit 11d reads the input value stored in the table (step S04), and executes an operation based on the control logic of the old device (step S05). The input / output data storage unit 11b stores the output data, which is the calculation result of the control logic unit 11d, in a table (step S06).

  The output unit 11f outputs the output data of the calculation result corresponding to the input data to the switching unit 15, the comparison unit 16, and the interface unit 11a (Step S07). The interface unit 11a transmits the output data to the control target of the simulator unit 3 defined by the table (step S08).

  When the input / output unit 16b of the comparison unit 16 receives the output data, the storage unit 16c stores the received output data (step S09). In addition, when the output data is received, the computer 2 displays the calculation result of the old device unit 11 on the display device 21. Then, the switching unit 15 switches so that the computer 2 is connected to the new device unit 12 (step S10).

  The interface unit 12a of the new device unit 12 waits for input data that simulates the input / output points of the plant 4 (NO in step S11). The generation unit 32 of the simulator unit 3 generates the same input data as the old device unit 11 as input data that simulates the input / output points of the plant 4. The output unit 33 of the simulator unit 3 transmits input data to the new device unit 12 via the network N.

  The interface unit 12a of the new device unit 12 receives the input data via the network N (YES in step S11). The input unit 12e inputs input data to the input / output data storage unit 12b (step S12). The input / output data storage unit 12b stores the input data according to the table format stored in the table storage unit 12c (step S13). The items in this table are the same as in FIG.

  The control logic unit 12d reads the input value stored in the table (step S14), and executes an operation based on the control logic of the new device (step S15). The input / output data storage unit 11b stores the output data of the calculation result in a table (step S16).

  The output unit 12f outputs the output data of the calculation result corresponding to the input data to the switching unit 15, the comparison unit 16, and the interface unit 12a (step S17). The interface unit 12a transmits the output data to the control target of the simulator unit 3 defined in the table (step S18).

  When the input / output unit 16b of the comparison unit 16 receives the output data, the storage unit 16c stores the received output data (step S19). In addition, when the output data is received, the computer 2 causes the display device 21 to display the calculation result of the new device unit 11.

  The determination unit 16a of the comparison unit 16 determines whether there is a difference between the output data of the new device unit 12 and the output data of the old device unit 11 (step S20). The input / output unit 16b outputs the comparison result to the computer 2 (step S21). The computer 2 causes the display device 21 to display the comparison result of the comparison unit 16.

  As described above, the simulator unit 3 simulates an input point based on a pattern set in the storage unit 31 in advance. Examples of such input point value determination methods are shown in FIGS.

  FIG. 7 is simply a method of setting a predetermined value for each input point. FIG. 8 shows a method of setting a predetermined value at an input point as an input value when the output point satisfies a predetermined condition. FIG. 9 shows a method for setting a predetermined value at the input point after a predetermined time has elapsed. These are examples, and the determination of the value of the input point is not limited to these. For example, an input value simulating the plant 4 can be set by combining the above three or two methods.

  The processing procedure of the above flowchart is an example, and the processing procedure of the present embodiment is not limited. For example, it is possible to freely set which of the calculation by the old apparatus unit 11 and the calculation by the new apparatus unit 12 is performed first. Further, the calculation result may be output to the computer 2 after the calculation by the old device unit 11 and the new device unit 12.

[3. effect]
According to the embodiment as described above, a part or all of the confirmation test can be performed in the factory by operating the old device unit 11 and the new device unit 12 in a virtual environment. For this reason, compared with the case where a confirmation test is implemented in the local operation of the new device and the old device in parallel, the period for updating the old device to the new device can be greatly reduced.

  Further, since the display device 21 displays the calculation results of the old control unit 11 and the new control unit 12 which are virtual environments, the operator can check whether the calculation results are equivalent. Furthermore, since the display device 21 also displays the comparison result by the comparison unit 16, it is possible to automatically confirm the malfunction of the new device.

[B. Second Embodiment]
[1. Constitution]
The configuration of this embodiment will be described with reference to FIG. The basic configuration of this embodiment is the same as that of the above embodiment. However, as shown in FIG. 10, in the present embodiment, the storage unit 31 in the simulator unit 3 stores plant data. Plant data is data at the time of actual plant operation. The plant data includes logic corresponding to troubles such as accidents that have occurred in the past.

  The plant data can be collected by the old apparatus 50 having a collection unit 57 and a plant data storage unit 58 as shown in FIG. The collection unit 57 is a processing unit that collects input / output data stored in the input / output data storage unit 53 of the local old device 50. The plant data storage unit 58 is a processing unit that stores the input / output data collected by the collection unit 57 as plant data.

[2. Action]
The operation of the present embodiment as described above will be described. That is, the collection unit 57 stores the input point data of the input / output data storage unit 53 in the plant data storage unit 58 at regular timing, for example, at a time interval t. It is assumed that the value of the input point data changes every time t as shown in FIG.

  The collected plant data is input to the simulator unit 3 via the network N or a removable storage medium storing the network N, and is stored in the storage unit 31. The input / output unit 32 of the simulator unit 3 transmits the plant data to the old device unit 11 and the new device unit 12 in the update test apparatus 1 in the same manner as the input data in the above embodiment.

  Input data based on such plant data is also stored in the input / output data storage units 11b and 12b, and calculation is performed by the control logic units 11d and 12d, as in the above embodiment. Thereby, the operation of an actual plant can be reproduced by the old apparatus unit 11 and the new apparatus unit 12 and a confirmation test can be performed. For example, the operation of the old device unit 11 and the new device unit 12 can be confirmed by input data based on logic corresponding to troubles such as accidents that have occurred in the past. In addition, by including the logic corresponding to the plant-specific characteristics and changes due to aging in the plant data, it is possible to check the operation of the old device unit 11 and the new device unit 12 based on the input data based on these logics. .

[3. effect]
According to the present embodiment as described above, plant data collected locally can be used in a test environment of a factory. There are various operation patterns in an actual power plant, but it has been difficult to reproduce all of these operation patterns in a factory. However, in this embodiment, since plant data is used, even in a factory, a test can be performed in an environment closer to the site. Therefore, it is not necessary to perform a test added locally, and the renewal period can be shortened.
