Description

  Embodiments described herein relate generally to a plant input / output confirmation apparatus and confirmation method.

  In steel plants that have been in operation for many years since the start of operation, there are cases where refresh work is performed to replace with new equipment. Such refresh work is called, for example, a steel plant renewal engineering business (hereinafter referred to as renewal engineering). In renewal engineering, the latest development connection diagram of the plant is obtained, and engineering work is started on the assumption that the object of remodeling is clear. When a difference is found between the latest deployment connection diagram and actual hardware in the business, the unknown point is investigated each time, and correct information is reflected in the latest deployment connection diagram.

  In steel plants that are still in operation, the period during which surveys can be conducted is limited. In addition, terminal blocks and cables to be surveyed may be deteriorated, and extreme caution is required during the survey. In addition, the survey may reveal new unclear points. For this reason, it may take a lot of time to confirm the accurate information of the existing steel plant.

  As for software, the latest software is obtained and converted into a program suitable for the new controller. At this time, in a plant that has been operating for many years and has repeatedly remodeled the equipment, determine whether all of the existing software is currently used or whether some of the software is included. It is difficult. The process of organizing unnecessary software is the optimal timing when the controller is updated, but there are many cases where unnecessary software is left as it is without being judged.

  In update engineering, in most cases, an update specification is created that summarizes what changes will be made by update engineering for the hardware information and software control functions of the plant, and what kind of system will eventually become. is there. The update specification is a document that summarizes the update policy. The update specification is created at an early stage of update engineering, and is created based on the latest deployment connection diagram and software originally obtained.

  In the development connection diagram of the plant, it is rare that all the latest information is reflected in the drawing after many modifications. When an unknown part is discovered in the development connection diagram, the existing process is surveyed to clarify the unknown point, and the engineering process is directly affected by the number of unknown points.

  The design is started on the premise that correct information is reflected in the latest development connection diagram and software. The problem is recognized as an unknown point when there is no consistency between the software described in the development connection diagram and the software. The time for designing the hardware and the time for creating the development connection diagram are, for example, before the time for designing the software. Inconsistencies were discovered after the start of software design, and the problems were sorted out through confirmation of the deployment connection diagram, confirmation of existing hardware at the site, and additional investigation of the software. For this reason, in many cases, it takes a long time to reflect the problem in the development connection diagram, and a lot of backtracking work is required to reflect the information in the latest development connection diagram.

  In addition, it is necessary to summarize the problems found in the update specification that summarizes the remodeling policy. In addition, depending on the scope of inconsistency, the policy may need to be reviewed from the ground up, and a huge amount of backtracking work may occur.

  For this reason, in a plant, it is desired to be able to check the input / output status of signals efficiently.

It is a flowchart which represents typically an example of operation | movement of the confirmation apparatus which concerns on embodiment.

Each embodiment will be described below with reference to the drawings.
The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between the parts, and the like are not necessarily the same as actual ones. Further, even when the same part is represented, the dimensions and ratios may be represented differently depending on the drawings.
In the present specification and drawings, the same elements as those described above with reference to the previous drawings are denoted by the same reference numerals, and detailed description thereof will be omitted as appropriate.

FIG. 1 is a block diagram schematically illustrating a plant according to the embodiment.
As shown in FIG. 1, the plant 2 includes equipment 4, a terminal block 5, an input / output module 6, a network 7, and a controller 8. Each of the equipment 4, the terminal block 5, and the input / output module 6 is provided in the plant 2. The facility equipment 4 is various equipment constituting the plant 2 such as a sensor, a switch, a lamp, or a drive device. The drive device is used for controlling a motor, for example.

  The terminal block 5 is used for connection with the equipment 4. Each of the plurality of facility devices 4 is connected to one of the plurality of terminal blocks 5. Each terminal block 5 has a plurality of terminals, for example. For example, the equipment 4 may be connected to each of the plurality of terminals of the terminal block 5. That is, a plurality of equipment 4 may be connected to one terminal block 5. The number of terminal blocks 5 may be the same as or different from the number of equipment 4. The terminal block 5 should just be prepared by the number which can connect each equipment 4 at least.

  Moreover, the plant 2 may have a terminal block 5 that is not connected to the equipment 4. The terminal block 5 that is not connected to the equipment 4 is preliminarily provided for the purpose of expanding the equipment 4 in the future, for example. For example, the terminal block 5 from which the equipment 4 is removed at the time of modification may be left as it is.

  The input / output module 6 is used for connection with the terminal block 5. The plurality of terminal blocks 5 are connected to one of the plurality of input / output modules 6. The input / output module 6 is, for example, a remote I / O. Each input / output module 6 has a plurality of input / output ports. The number of input / output ports provided in the input / output module 6 may be the same as or different from the number of terminals provided in the terminal block 5.

  For example, when the number of input / output ports provided in the input / output module 6 is the same as the number of terminals provided in the terminal block 5, the number of input / output modules 6 is the same as the number of terminal blocks 5. When the number of input / output ports provided in the input / output module 6 is larger than the number of terminals provided in the terminal block 5, a plurality of terminal blocks 5 are connected to one input / output module 6. In this case, the number of input / output modules 6 is smaller than the number of terminal blocks 5. On the other hand, when the number of input / output ports provided in the input / output module 6 is smaller than the number of terminals provided in the terminal block 5, a plurality of input / output modules 6 are connected to one terminal block 5. The In this case, the number of input / output modules 6 is larger than the number of terminal blocks 5. The input / output modules 6 need only be prepared for at least the number of terminals that can be connected to the terminals 5. The plant 2 may have an input / output module 6 that is not connected to the terminal block 5.

  Each input / output module 6 and the controller 8 are connected to a network 7. That is, the controller 8 is connected to each input / output module 6 via the network 7, and is connected to each facility device 4 via each input / output module 6 and each terminal block 5. The controller 8 may be directly connected to each input / output module 6 without going through the network 7. For example, when the equipment 4 is a sensor, the controller 8 acquires a detection value from the equipment 4. For example, when the equipment 4 is a driver, the controller 8 controls the operation of the driver based on the detection value of each sensor. Thus, the controller 8 controls the operation of at least one of the equipment devices 4. For example, the controller 8 controls the operation of the plant 2. For example, when the plant 2 is a rolling line of a steel plant, the controller 8 controls the rolling of the material to be rolled by a rolling mill.

  The plant 2 may have a plurality of controllers 8. A plurality of controllers 8 may be connected to the network 7. For the network 7, for example, a local area network (LAN) or a wide area network (WAN) is used.

  The plant 2 further includes a confirmation device 10 and a data logger 12. The confirmation device 10 is connected to the network 7. The confirmation device 10 is connected to the controller 8 via the network 7. The confirmation device 10 may be directly connected to the controller 8 without going through the network 7. The confirmation device 10 confirms the signal input / output status in the plant 2. The confirmation device 10 confirms the input / output status of signals between each equipment device 4 and the controller 8, for example. Then, the confirmation device 10 displays the result of confirmation of the signal input / output status. In other words, the confirmation device 10 notifies the designer or the like of the result of confirmation of the signal input / output state. Thereby, the confirmation apparatus 10 enables a designer etc. to confirm the input / output state of a signal efficiently.

  The data logger 12 is connected to the input / output module 6. In this example, the data logger 12 is connected to the output port side of the input / output module 6. On the contrary, the data logger 12 may be connected to the input port side of the input / output module 6. The data logger 12 acquires an input / output signal history of the input / output module 6 within a certain period. The data logger 12 is connected to the network 7. The data logger 12 sends the acquired input / output signal history to the confirmation apparatus 10 via the network 7. The confirmation device 10 stores a history of input / output signals acquired by the data logger 12.

  In this example, one data logger 12 is connected to one input / output module 6. For example, every time a certain period elapses, the input / output module 6 connected to the data logger 12 is replaced, and the history of each input / output module 6 is sequentially acquired. For example, a plurality of data loggers 12 may be provided in each of the plurality of input / output modules 6 and the history of each input / output module 6 may be simultaneously acquired.

FIG. 2 is a block diagram schematically illustrating the confirmation device according to the embodiment.
As shown in FIG. 2, the plant input / output confirmation device 10 includes an input / output information acquisition unit 20, an input / output history information collection unit 21, a terminal block information acquisition unit 22, a difference extraction unit 23, and an input / output. A difference display unit 24, a terminal block difference display unit 25, a survey location extraction unit 26, and a survey location display unit 27 are provided.

  The confirmation device 10 is realized on a general-purpose personal computer (PC), for example. Each of the above-described units 20 to 27 is, for example, a logical block provided in a PC processor. The confirmation device 10 may be composed of one PC or a plurality of PCs.

  The input / output information acquisition unit 20 acquires the input / output basic data 30. The input / output basic data 30 represents, for example, a name of a signal input / output to / from the input / output module 6 (hereinafter referred to as an input / output signal name). The input / output basic data 30 represents, for example, a plurality of input / output signal names input / output to / from a plurality of input / output ports of the input / output module 6. The input / output basic data 30 is created for each of the plurality of input / output modules 6, for example. The input / output information acquisition unit 20 acquires a plurality of input / output basic data 30 created corresponding to each of the input / output modules 6.

  The input / output information acquisition unit 20 acquires each input / output basic data 30 by, for example, importing configuration data of each input / output module 6 output from the engineering tool of the controller 8. Each input / output basic data 30 may be input to the input / output information acquisition unit 20 by manual input. The plant 2 includes various generations of controllers 8 and input / output modules 6. For this reason, it is preferable that the input / output information acquisition unit 20 can select a method of acquiring from the controller 8 and a method of acquiring manually input information.

  The input / output information acquisition unit 20 creates input / output basic information 31 from the acquired input / output basic data 30. The input / output information acquisition unit 20, for example, combines the input / output basic data 30 according to a predetermined input / output signal name and the actual arrangement order of the input / output modules 6, thereby providing the input / output basic information 31. Create

  The input / output history information collection unit 21 holds the history within a set period for the input / output signals registered by the input / output basic information 31 and accumulates them in the storage device. The storage device may be provided in the input / output history information collection unit 21 or may be connected to the input / output history information collection unit 21 via the network 7. The input / output history information collection unit 21 is connected to the data logger 12 via, for example, the network 7 and acquires the history of input / output signals from the data logger 12. For example, the input / output history information collection unit 21 acquires the history for each of the plurality of input / output signals of the plurality of input / output modules 6. Thereby, in each input / output module 6, the input / output history information 32 representing the signals having and without the input / output history can be created.

  The input / output history information collection unit 21 creates input / output history information 32 from the acquired input / output signal history of each input / output module 6. The input / output history information 32 represents the history of input / output signals input / output to / from the plurality of input / output modules 6 within a certain period. The input / output history information 32 is created, for example, in a form in which information is added to the input / output basic information 31. The input / output history information collection unit 21 inputs the created input / output history information 32 to the difference extraction unit 23.

  For example, for the location where the input / output module 6 is directly connected to the controller 8 and it is difficult to obtain the history for a certain period, the presence / absence of the input / output history may be manually input to the input / output history information collection unit 21. .

  The terminal block information acquisition unit 22 acquires terminal block data 33. The terminal block data 33 represents usage locations of a plurality of terminals on the terminal block 5. In other words, the terminal block data 33 represents locations where the electric wires are connected to the plurality of terminals of the terminal block 5. The terminal block information acquisition unit 22 acquires a plurality of terminal block data 33 for each of the plurality of terminal blocks 5.

FIG. 3 is a schematic diagram illustrating an example of a terminal block investigation method.
In obtaining the terminal block data 33, for example, as shown in FIG. 3, the conductive sheet 60 is pasted on the terminal block 5. For example, each terminal 5 a of the terminal block 5 is short-circuited by the conductive sheet 60. And the probe 64 is stabbed into the electric wire 62 connected to the terminal block 5, and the use location of the existing terminal block 5 is investigated by confirming conduction | electrical_connection between the electroconductive sheet 60 and the probe 64. FIG.

  For example, in the plant 2 where remodeling is being performed, the electric wires 62 that have become unnecessary due to changes in the equipment 4 or the like may remain as they are. The unnecessary electric wire 62 may appear to be connected to the terminal 5a and may not be electrically connected. In this case, the electrical connection between the terminal 5a and the electric wire 62 cannot be determined by visual observation alone. For this reason, as described above, the probe 64 is pierced into the electric wire 62 and the conduction between the conductive sheet 60 and the probe 64 is investigated. Thereby, when there is conduction, the terminal 5a is used, and when there is no conduction, it can be determined that the terminal 5a is not used. Terminal block data 33 is generated from the terminal block survey result 34 obtained in this survey. This operation is repeated for the number of target terminal blocks 5, and the obtained terminal block data 33 is input to the terminal block information acquisition unit 22.

  The terminal block information acquisition unit 22 collects the input terminal block data 33 to create terminal block information 35 representing the use location of each terminal 5 a of each terminal block 5 from each terminal block data 33. . That is, the terminal block information 35 is created from the terminal block survey result 34 of each terminal block 5. Then, the terminal block information acquisition unit 22 inputs the created terminal block information 35 to the difference extraction unit 23.

  The difference extraction unit 23 receives input / output history information 32 and terminal block information 35 as well as existing input / output data 36 and existing terminal block data 37. The existing input / output data 36 is known information of each input / output signal name input / output to / from each input / output module 6. The existing input / output data 36 is, for example, a signal list created from the latest development connection diagram data. The existing input / output data 36 may be created from, for example, drawing data of another type of connection wiring diagram such as a ladder diagram. Thus, the existing input / output data 36 is created from the drawing data of the plurality of input / output modules 6 and represents input / output signals input / output to / from the plurality of input / output modules 6.

  The existing terminal block data 37 is known information representing the use location of each terminal 5 a of each terminal block 5. The existing terminal block data 37 is created from drawing data such as terminal block diagram data, for example. The existing terminal block data 37 is created from the drawing data of the plurality of terminal blocks 5, and represents the use location of each of the plurality of terminals 5 a of the plurality of terminal blocks 5.

  The difference extraction unit 23 compares the input / output history information 32 that is the latest information with the existing input / output data 36 that is the existing information, and extracts a difference between the input / output history information 32 and the existing input / output data 36. The difference extraction unit 23 creates an input / output difference list 40 representing this difference from the difference between the extracted input / output history information 32 and the existing input / output data 36.

  Similarly, the difference extraction unit 23 compares the terminal block information 35 that is the latest information with the existing terminal block data 37 that is the existing information, and extracts the difference between the terminal block information 35 and the existing terminal block data 37. . And the difference extraction part 23 produces the terminal block difference list 41 showing this difference from the difference between the extracted terminal block information 35 and the existing terminal block data 37.

  The difference extraction unit 23, by comparing each information, for the input / output module 6 and the terminal block 5, the existing information matches the latest information, the existing information is not in the latest information, the existing information is not, Classify into three types of the latest information.

  That is, the difference extraction unit 23 matches the input / output signal represented by the input / output history information 32 and the input / output signal represented by the existing input / output data 36 in the input / output history information 32 and the existing input / output data 36. The signals are classified into three types of signals: signals in the input / output history information 32 that are not in the existing input / output data 36, and signals that are in the existing input / output data 36 and are not in the input / output history information 32.

  Similarly, the difference extraction unit 23 matches the input / output signal represented by the terminal block information 35 and the use location of each terminal 5 a represented by the existing terminal block data 37 in the terminal block information 35 and the existing terminal block data 37. The terminal 5a and terminal block information 35 are classified into three types of terminals 5a: a terminal 5a that is not in the existing terminal block data 37 and a terminal 5a that is in the existing terminal block data 37 and not in the terminal block information 35.

  The input / output difference list 40 and the terminal block difference list 41 include the above three types of information. The input / output difference list 40 is created, for example, as a list in which comparison results are added to the existing input / output data 36. For example, a signal having no information in the existing input / output data 36 and having an input / output history in the latest input / output history information 32 is newly added to the input / output difference list 40 to create a list.

  The input / output difference display unit 24 displays an input / output difference list 40. For example, the input / output difference display unit 24 displays the input / output difference list 40 as an expanded connection diagram. The input / output difference display unit 24 may display the input / output difference list 40 in the form of another connection wiring diagram without being limited to the form of the developed connection diagram.

  In addition, the input / output difference display unit 24 uses, for example, image data acquired from an existing developed connection diagram, and displays only the information selected on the input / output difference display unit 24 so as to be superimposed on the acquired image data. For example, the input / output difference display unit 24 selectively displays the three types of information included in the input / output difference list 40.

  The terminal block difference list 41 is created, for example, as a list in which the comparison result is added to the existing terminal block data 37. For example, the terminal 5a having no information in the existing terminal block data 37 and having the connection information in the terminal block information 35, which is the latest information, is newly added to the terminal block difference list 41 to create a list.

  The terminal block difference display unit 25 displays a terminal block difference list 41. The terminal block difference display unit 25 displays, for example, the terminal block difference list 41 as a terminal block diagram. Further, the terminal block difference display unit 25 selectively displays the above three types of information included in the terminal block difference list 41, for example.

  The confirmation device 10 includes, for example, a monitor not shown. The input / output difference display unit 24 and the terminal block difference display unit 25 display the input / output difference list 40 and the terminal block difference list 41 on the monitor. The monitor that displays the input / output difference list 40 may be different from the monitor that displays the terminal block difference list 41. That is, each of the input / output difference display unit 24 and the terminal block difference display unit 25 may include a monitor. The input / output difference display unit 24 and the terminal block difference display unit 25 may be, for example, a separately connected PC.

  The survey location extraction unit 26 receives the input / output difference list 40 and the terminal block difference list 41 and the interface information 42. The interface information 42 represents the connection between each input / output module 6 and each terminal block 5 provided in the plant 2.

  The survey location extraction unit 26 extracts software survey locations of each terminal block 5, each input / output module 6, and controller 8 based on each input information. For example, even if a signal is normally assigned between the software (controller 8) and the input / output module 6, the survey location extraction unit 26 corresponds to an input / output signal in which the electric wire 62 is not connected to the terminal block 5. A location corresponding to an input / output signal to which no signal is assigned between the software and the input / output module 6 is extracted as a location requiring investigation, although the connection of the electric wire 62 exists in the location and the terminal block 5.

  For example, even if a signal is normally assigned between the software and the input / output module 6, it is considered that unnecessary software remains in the controller 8 when the electric wire 62 is not connected to the terminal block 5. . On the other hand, although there is a connection of the electric wire 62 in the terminal block 5, if no signal is assigned between the software and the input / output module 6, the unnecessary electric wire 62, the terminal block 5, etc. remain. Conceivable.

  The survey location extraction unit 26 creates a survey location list 43 from the extracted required survey locations. The survey location display unit 27 displays the survey location list 43. The survey location display unit 27 displays, for example, the survey location required on the developed connection diagram or the terminal block diagram based on the survey location list 43. In addition, the survey location display unit 27 displays the survey content at a location requiring survey, for example. The survey location display unit 27 allows the designer to edit the description of the survey content, for example, by operating an operation input unit (not shown). The investigation content may be edited by the confirmation device 10 or may be performed from another terminal connected via the network 7.

  FIG. 4 is a flowchart schematically illustrating an example of the operation of the confirmation device according to the embodiment. As shown in FIG. 4, in the confirmation of plant input / output by the confirmation device 10, first, the input / output information acquisition unit 20 acquires a plurality of input / output basic data 30 corresponding to each of the plurality of input / output modules 6. . The input / output information acquisition unit 20 creates input / output basic information 31 from the acquired input / output basic data 30 and inputs the created input / output basic information 31 to the input / output history information collection unit 21.

  The input / output history information collection unit 21 acquires the input / output signal history of each input / output module 6 based on each input / output basic information 31 and creates the input / output history information 32 from each acquired history. The input / output history information collection unit 21 inputs the created input / output history information 32 to the difference extraction unit 23.

  Next, the terminal block information acquisition unit 22 acquires a plurality of terminal block data 33 corresponding to each of the terminal blocks 5. The terminal block information acquisition unit 22 creates terminal block information 35 from each acquired terminal block data 33 and inputs the created terminal block information 35 to the difference extraction unit 23.

  The terminal block data 33 may be acquired by the terminal block information acquisition unit 22 before the input / output basic data 30 is acquired by the input / output information acquisition unit 20. The terminal block information 35 may be generated by the terminal block information acquisition unit 22 before the input / output history information 32 is generated by the input / output history information collection unit 21.

  The difference extraction unit 23 extracts a difference between the input / output history information 32 and the existing input / output data 36 and creates an input / output difference list 40. The input / output difference display unit 24 displays an input / output difference list 40. For example, the input / output difference display unit 24 selectively displays information on each of the three types of input / output signals included in the input / output difference list 40.

  Thereby, in the confirmation device 10, by referring to the input / output difference list 40 displayed on the input / output difference display unit 24, the designer or the like can calculate the difference between the input / output history information 32 and the existing input / output data 36. It can be easily confirmed. That is, the difference in input / output signals between the latest information and the existing information can be easily confirmed. For example, the necessity / unnecessity of input / output signals input / output to / from each input / output module 6 can be easily confirmed. Therefore, the confirmation device 10 can efficiently confirm the input / output status of input / output signals input / output to / from each input / output module 6.

  Further, the difference extraction unit 23 extracts a difference between the terminal block information 35 and the existing terminal block data 37 and creates a terminal block difference list 41. The terminal block difference display unit 25 displays a terminal block difference list 41. The terminal block difference display unit 25 selectively displays information on each of the three types of terminals 5a included in the terminal block difference list 41, for example.

  Thereby, in the confirmation apparatus 10, by referring to the terminal block difference list 41 displayed on the terminal block difference display unit 25, the designer or the like can easily perform the difference between the terminal block information 35 and the existing terminal block data 37. Can be confirmed.

  The difference extraction unit 23 inputs the created input / output difference list 40 and terminal block difference list 41 to the investigation location extraction unit 26. Based on the input / output difference list 40, the terminal block difference list 41, and the interface information 42, the survey location extraction unit 26 extracts and extracts the survey required locations of the software of each terminal block 5, each input / output module 6 and the controller 8. A survey location list 43 is created from the required survey locations. The survey location display unit 27 displays the survey location list 43.

  Thereby, in the confirmation apparatus 10, by referring the investigation location list | wrist 43 displayed on the investigation location display part 27, the investigation required location of the plant 2 can be confirmed easily. For example, unnecessary software and terminal block 5 can be easily recognized.

  In the confirmation apparatus 10 according to the present embodiment, for example, in plant renewal engineering work, it is possible to start an investigation of necessity / unnecessity of input / output signals at an early stage of design. As a result, the necessity of some functions in the software can be examined from the initial stage of the design, so that the backtracking work can be reduced and the efficiency of the engineering work can be improved.

  In addition, since it is possible to clarify the remodeled portion in the existing equipment, for example, there is no description in the existing software plan, and it is possible to increase the possibility that the added function can be found in the initial stage of engineering work. As a result, problems can be shared as common knowledge with the user before the start of software design, and necessary investigations and studies can be started at an early stage of engineering work.

  Also, software design is often not started or just started at the time of hardware design. For this reason, it is possible to correct the possibility that the hardware is not organized by leaving the unknown part of the hardware as an existing function without sufficient examination.
