Description

  The present invention relates to a technique for setting operation authority of a process monitoring control system that performs process control of a plant (for example, feedback control, sequence control, and status monitoring thereof).

  In the process monitoring and control system, a plant operator monitors and controls processes executed in the plant. The plant operator, in the instrument room that performs process monitoring and control, grasps the operating state of the process from various plant monitoring information displayed on the display screen of the operation console, and performs the required operation using a keyboard or the like ( For example, refer nonpatent literature 1.).

  In recent years, plant operators have been given authority to operate according to their own level (eg, professional level, technical experience level, etc.), and the operation of the plant is prevented by preventing them from performing more than necessary. Security may be set for the. In the field of the process industry, plant malfunctions caused by incorrect operating operations can cause serious obstacles for safety and production planning. Therefore, a security setting / management system based on the presence or absence of operation authority is a necessary function.

  In addition, there is an increasing demand for monitoring and controlling a plant from a remote location using a portable terminal, and a security system is indispensable from the viewpoint of preventing unauthorized access and manipulation.

  Generally, as described in Patent Document 1, a security system in a process monitoring control system has definition data in which a plant operator ID and a function that can be operated by the plant operator are associated with each other. Sometimes, it is realized by referring to the definition data to determine whether the operation is possible and permitting the operation based on the determination result.

  However, in the process monitoring control system, there are many items related to operable functions such as monitoring and control, and it is not an easy task to create the definition data corresponding to these items. In order to actually perform this work, the security administrator who manages the operation authority, from the operation authority registration screen, for each of the above items, each plant operator group consisting of each plant operator or a plurality of plant operators. It is necessary to register whether or not there is an operation authority in association with the definition data. That is, the security administrator must perform operation authority registration work for each of the above items by the number of plant operators or plant operator groups. Thus, this registration work is a heavy burden for the security administrator.

  An object of the present invention is to provide a process monitoring control system capable of easily registering / changing operation authority, which is security management, a driving console used therefor, and an operation authority setting method.

  In order to achieve the above object, the process monitoring control system of the present invention is a process monitoring control system capable of executing an operation simulation for performing process monitoring control in a pseudo manner before performing process monitoring and control of the plant main operation. An operation authority setting unit for setting an operation authority of an operator of the process monitoring control system, and the operation authority setting unit performs the operation authority as part of the operation simulation during the execution of the operation simulation. Is set.

  In order to achieve the above object, the operation console used in the process monitoring control system is configured as follows. An operation console used to perform operations necessary for process monitoring and control of plant operation. Process monitoring information is input via a process control device, and process monitoring and control are performed in the process control device. In the operation console of the process monitoring control system that performs necessary operations, the operation console performs pseudo process monitoring and control without actual operation before performing process monitoring and control of the plant main operation. It has a driving simulation mode. In addition, the operation console sets the operation authority of the plant operator as a part of the simulation mode during execution of the operation simulation mode on condition that the permission signal is received from the administrator who manages the operation authority. A processing program to be executed is included.

  Further, the driving console includes a display device and a keyboard device, and displays an operation simulation execution screen on the display device, and sets the operation authority in an interactive manner via the screen and the keyboard device.

  We also propose the following operation authority setting method for the process monitoring control system. That is, before performing process monitoring and control of the plant main operation, using the operation console used for operation of the process monitoring control system, in the process monitoring control system that executes an operation simulation for performing the process monitoring control in a pseudo manner, This is an operation authority setting method for registering or changing the operation authority of a plant operator. The feature of this operation authority setting method is the step of receiving an operation authority setting permission signal from an operation authority administrator that manages the granting and changing of the operation authority of the plant operator, and on the condition that the permission signal is received, During the execution of the operation simulation via the operator console, as part of the operation simulation mode, an operation authority setting screen for interactively setting the operation authority of the plant operator on the display device of the operator console is displayed. A step of displaying.

  Furthermore, the present operation authority setting method is a step of temporarily storing the setting items in a storage device when a setting related to registration or change of the operation authority of the plant operator is made through the operation of the plant operator in the operation simulation mode. The operation authority of the plant operator temporarily stored in the storage device is called from the storage device to the display device in order to obtain the check and approval of the operation authority manager.

  According to the present invention, in a process monitoring and control system, a plant operator himself / herself uses a plant simulation under the control of a system security administrator (operation authority manager) using an operation simulation performed before the plant is actually operated. Registration and change of a number of items related to the operation authority of the operator can be easily executed visually and easily. As a result, the security of the process monitoring control system can be ensured and the burden of setting the operation authority of the security administrator at the time of security construction can be reduced.

  The present invention pays attention to the fact that an operation simulation is performed before the actual operation in the process monitoring control system, and the plant operator performs a series of operations under the authority of the operation authority manager (security manager) during the execution of the operation simulation. Performs input and setting operations necessary for registration / change of operation authority through simulation operations. Therefore, registration / change of the operation authority can be easily performed as part of the driving simulation. Embodiments of the present invention will be described below with reference to FIGS.

  First, an example of plant control by the process monitoring control system will be described with reference to FIG. Here, a case where the process monitoring control system detects the flow rate of the oil flowing into the tank and controls the opening and closing of the valve is illustrated.

  The process monitoring control system 1 includes plant control devices 10 and 12, operation consoles 50, 52 and 54, and a communication line 40, and controls the plant 2. Further, a network device 60 such as a router may be provided in order to monitor and control the plant from a remote location using the mobile terminal 70 using the network infrastructure 72 of the communication company.

  The driving consoles 52 and 54 are each composed of, for example, one driving console, and the driving console 50 is composed of two main and sub driving consoles. The operation consoles 50, 52, 54 are connected to the plant control devices 10, 12 via the communication line 40, authenticate the plant operator, and give the operation authority of the plant 2. The plant operator uses the operation consoles 50, 52, and 54 to collect process data, transfer setting request texts, and obtain responses to the plant control devices 10 and 12, thereby monitoring the plant. Execute control. Information necessary for monitoring and controlling the plant 2 is displayed on the display devices of the operation consoles 50, 52 and 54. Furthermore, since the operation console 54 is also connected to the network device 60, the plant operator can monitor and control the plant 2 from a remote location.

  The plant 2 includes tanks 20 and 30 for storing fluid, for example oil, flow meters 22, 24 and 28 as sensors, and process valves 26, 32 and 34. Oil flows into the tank 20 in two systems, and the flow meters 22 and 24 detect the amount of oil flowing in each system. When the process valve 26 is opened, oil flows from the tank 20 to the tank 30. The flow meter 28 is provided after the process valve 26 and measures the flow rate of oil flowing from the tank 20 to the tank 30. The process valves 32 and 34 are provided in the outflow side piping of the tank 30, and oil flows out of the tank 30 when the valve is opened. The process valves 26, 32, and 34 are all closed in the initial state.

  Hereinafter, an example in which the plant control devices 10 and 12 control the plant 2 will be described. The plant operator can operate the plant control devices 10 and 12 by any of the operation consoles 50, 52, and 54. In this embodiment, the operation operator console is assumed to be operated from the operation console 50 as an example. Only 50 will be described. The description for the driving console 50 can also be applied to the driving consoles 52 and 54.

  The plant control device 10 detects the flow rates of the two systems of oil flowing into the tank 20 with the flow meters 22 and 24 and takes in the detection signals. When the total amount of oil that has flowed into the tank 20 reaches a predetermined amount such as 10 t, the plant control device 10 outputs a control signal for opening the valve to the process valve 26, and from the tank 20 to the tank 30 via the process valve 26. Let the oil spill. Further, the plant control device 10 controls the process valve 26 so as to close after a predetermined time elapses, for example, 10 minutes after opening. The flow rate of oil flowing from the tank 20 to the tank 30 is measured by the flow meter 28 and taken into the plant control apparatus 10.

  The plant control device 12 controls the opening and closing of the process valves 32 and 34. By controlling the process valve 32 to open when the amount of oil flowing into the tank 30 reaches a predetermined amount, it is possible to take out the clean oil remaining in the upper part of the tank 30. Moreover, after taking out this oil, the control which opens the process valve 34 is performed, and the contaminated oil which has settled is discharged | emitted as a drain.

  The inflow / outflow amounts of oil to the tank 20 detected by the flow meters 22, 24, 28 are taken into the operation console 50 via the plant control device 10 and the communication line 40, and the display device of the operation console 50 is displayed. Is displayed. Further, the open / closed state of the process valves 26, 32, 34 is also taken into the operator console 50 via the plant controller 10 or the plant controller 20 and the communication line 40 and displayed on the display device of the operator console 50. . Therefore, the plant operator can grasp the oil inflow / outflow status of the tanks 20 and 30 by monitoring the display device of the operation console 50. Further, when the opening / closing control of the process valves 32 and 34 is performed manually, it can be performed from the operation console 50.

  As described above, the plant operator monitors the detection signals output from the flow meters 22, 24, 28, the status of opening / closing control of the process valves 26, 32, 34, and the amount of oil in the tanks 20, 30. Or open / close control of the process valve manually. An operation authority is required for these monitoring and operation operations, and this operation authority must be registered in the process monitoring control system 1 as security information.

  FIG. 1 shows only tanks 20 and 30 and flow meters and process valves arranged in the vicinity thereof as an example of the plant, but the actual plant is larger, and a reactor with a jacket or A pump and a control valve capable of controlling the opening degree are also provided, but the illustration thereof is omitted here.

  First, before entering the description of the features of the present invention, a general security system executed in this embodiment will be described. The driving console 50 in a general security system includes a man-machine interface (MMI) 101 and a monitoring control device 100 as shown in FIG. The same applies to the other operation consoles 52 and 54.

  The MMI 101 has input / output interfaces such as a touch screen 102, a display device 103, a keyboard 104, a mouse 105, and a printing device 106. The plant operator operates the monitoring control device 100 via the MMI 101.

  The monitoring control device 100 includes a storage device 110 and performs an operation authority determination process 115. The storage device 110 stores an operator list file 111 and an operation authority definition file 112. In the operator list file 111, the ID and password of the plant operator who operates this process monitoring control system are registered in advance. In the operation authority definition file 112, what operation authority each plant operator has is registered in advance.

  The operation authority determination process 115 in a general security system will be described. When the process is started (step 120), the operator is confirmed from the registration ID and password input by the plant operator and authenticated (step 121). For operator confirmation and authentication, the operator list file 111 is referred to.

  As a result of authentication, if the plant operator is a valid operator registered in the operator list file 111, the plant operator can input an operation (step 122).

  For this operation, the operation authority definition file 112 is referred to and it is determined whether the plant operator has the operation authority (step 123). In step 124, the process branches to step 125 when it is determined that the user has the operation authority, and to step 127 when it is determined that the user does not have the operation authority.

  When the plant operator has the operation authority, the operation process is executed (step 125), and the operation result is output (step 126).

  In step 127, it is determined whether or not to continue processing. If the plant operator continues to operate, the process returns to step 122 to continue the above process, and if no further operation is performed, the process proceeds to step 128 to end the process.

  Generally, the process monitoring and control system security system is established by processing in this manner. However, the security (operation authority) administrator must create the operation authority definition file 112 in advance. This is a burdensome work that requires a security (operation authority) administrator to register necessary items for the required number of people.

  Therefore, in the present invention, paying attention to the point that the operation simulation is executed before the plant operation, the operation authority definition file 112 is obtained when the plant operator performs an operation necessary for registration / change of the operation authority during the operation simulation. Was created. In the operation authority definition file 112, the operation authority for each plant operator permitted by the security (operation authority) administrator is registered.

  Here, the operation simulation mode is an operation mode in which the plant operator performs a process monitoring control performed before the actual operation in a pseudo manner through the operation console, and does not involve actual operation. The operation authority setting process is performed when the security (operation authority) administrator switches the mode of the operation console (for example, the operation console 50) in which the plant operator executes the operation simulation to the operation authority simulation mode. The mode switching mode is as follows.

  For example, the plant operator sets the operation console of the plant operator (here, for example, the operation console 50) to the operation console (here, for example, the operation console 54) of the security (operation authority) administrator. ) Mode is switched from the normal simulation mode to the operation authority simulation mode. Upon receiving this request, the security (operation authority) manager changes the mode of the operator console 50 of the plant operator to the operation authority simulation mode. Switch. These mode switching requests and switching are generally performed through the communication line 40 that connects the driver consoles. However, it is also possible for the security (operation authority) manager to switch the mode of the operation console 50 of the plant operator to the operation authority simulation mode by a switching request by verbal exchange directly. It is also possible for the security (operation authority) administrator to directly operate the plant operator's console 50 to switch to the operation authority simulation mode.

  Even if there is no request from the plant operator, the security (operation authority) administrator issues an instruction to switch from the normal simulation mode to the operation authority simulation mode to the plant operator's operation console mode, and the plant operator It is possible to switch the operator's operation console mode to the operation authority simulation mode.

  A processing example of the operation authority simulation mode in the process monitoring control system according to the present embodiment is shown in FIG. FIG. 2 shows the configuration and functions of the driving console 50 (the same applies to the other driving consoles 52 and 54). Elements common to the driver console 50 in the general security system shown in FIG. However, in the operation authority definition file 112, default or dummy values are registered in the initial state before the plant operation, and the operation authority of each plant operator is registered in accordance with the operation authority registration method according to the present invention described below. To go.

  Note that the operation authority may be registered for each plant operator or for each plant operator group including a plurality of plant operators. In the following, the case of registering for each plant operator will be described, but even when registering for each plant operator group, the plant operator representing the plant operator group performs the following registration work, so that the operation according to the present invention is performed. The registration method of authority can be applied.

  Hereinafter, the flow of processing in the operation authority simulation mode, which is executed by the operation authority determination process 115 of the operation console of the process operator, will be described.

  First, the operation mode of the operation console 50 of the plant operator is switched from the normal mode to the operation authority simulation mode by the operation of the operation console 54 by the security (operation authority) administrator (step 401). Incidentally, the normal mode is a normal operation simulation mode and an actual plant operation mode. In the operation authority simulation mode, even if the operation console 50 is operated, only the monitoring and control of the plant by the simulation are executed, and the actual monitoring and control of the plant cannot be performed. Is possible.

  FIG. 3 shows an example of the plant monitoring screen in the normal mode and the operation authority simulation mode displayed on the display device 103 of the operation console 50. Actually, only the plant monitoring screen of the selected operation mode among the normal mode and the operation authority simulation mode is displayed, but in FIG. 3, the screens of the above two modes are shown together for comparison and explanation.

  On the plant monitoring screen 212 in the normal mode, a plant operation control instrument 206 that is an instrument for plant monitoring and control, and a mode display frame 220 labeled “N mode” (normal mode) are displayed. On the plant monitoring screen 208 in the operation authority simulation mode, a plant operation operation instrument 206 and a mode display frame 220 labeled “SM mode” (simulation mode) are displayed. When the operation mode of the operation console 50 is switched from the normal mode to the operation authority simulation mode (step 401 in FIG. 2), the plant monitoring screen 208 in which the display of the mode display frame 220 is switched from “N mode” to “SM mode” is displayed. It is displayed and it can be seen visually that the operation authority simulation mode has been switched.

  The plant operation control instrument 206 can be operated from the plant monitoring screens 208 and 212 with a keyboard 104 and a mouse 105 not shown in FIG.

  Returning to the description of the operation authority determination processing 115 (FIG. 2). When starting operation in the operation authority simulation mode, the plant operator inputs his / her ID and password via the MMI 101.

  In the operation authority determination process 115, in the operator authentication process (step 121), the operator list file 111 is referred to, and the input ID and password are confirmed and authenticated. When it is confirmed that the input ID and password are registered in the operator list file 111, the plant operator is determined to be valid, and the simulation operation of the process monitoring control system is started.

  In this state, the plant operator operates the plant operation operation instrument 206 (FIG. 3) through the display device 103 with the keyboard 104 or the mouse 105 (for example, parameter setting for process control such as temperature operation using the thermometer) (step) 122) In step 123, the operation authority definition file 112 is referred to, and it is determined whether or not the plant operator has the operation authority for the currently performed operation. In the operation authority simulation mode, subsequent operations are executed regardless of the determination result. Then, an operation authority change window is displayed (step 402). The plant operator can newly set or change the operation authority from the operation authority change window.

  Here, the operation authority change window will be described with reference to FIG. FIG. 4 is an example when the plant operator performs an operation to change the set value (SV value) of the instrument displayed on the plant operation control instrument 206 on the plant monitoring screen 208. In this case, the data change window 301 is displayed in step 122 by the operation of the plant operation control instrument 206. When the plant operator changes the SV value in the data change window 301, an operation authority change window 302 is displayed (step 402). The plant operator can register or change the operation authority by selecting “operation possible” or “operation impossible” in the operation authority change window 302 and selecting the “change” button. When “operation possible” is selected, the user has operation authority. When “operation impossible” is selected, the user has no operation authority.

  The description of the operation authority determination process 115 (FIG. 2) will be continued. In the operation authority determination process 115, it is determined whether or not the operation authority has been changed in the operation authority change window 302 shown in FIG. 4 (step 403). If there is a change, the change contents of the operation authority are registered in the operation authority definition file 112 in step 404.

  Thereafter, in step 124, if there is an operation authority for the operation performed by the plant operator (change of the SV value in the example of FIG. 4), the process proceeds to step 125, and processing based on this operation is executed. The execution of the process of step 125 in the operation authority simulation mode does not actually control the plant, but is performed in a pseudo manner according to a predetermined method such as artificially inputting parameters necessary for the operation of the plant. is there.

  Then, an operation result for outputting the execution result of the process to a file or displaying it on the screen is output (step 126). The output of the operation result is not a result of actually controlling the plant in the operation authority simulation mode, but a pseudo operation result according to a predetermined method.

  After outputting the operation result, the process proceeds to step 127 to determine whether to continue the process. If the plant operator continues to operate, the process returns to step 122 to continue the above process. If no further operation is performed, the process proceeds to step 405, where the operation authority registration / change process ends.

  If it is determined in step 124 that there is no operation authority for the operation performed by the plant operator (in the example of FIG. 4, the SV value is changed), the process proceeds to step 127 to determine whether to continue the process.

  When the process proceeds to step 405, the process in the operation authority simulation mode ends (step 128), and the registration / change by the plant operator is completed.

  That is, each operation console of the present embodiment has an operation simulation mode for performing pseudo process monitoring and control without actual operation before performing process monitoring and control of the actual operation of the plant, and the plant operation. A processing program for executing the setting of the operation authority of the worker as part of the simulation mode during execution of the operation simulation mode on condition that a permission signal is received from a security (operation authority) administrator who manages the operation authority. Have.

  In addition, an embodiment for ensuring the security management of the process monitoring control system will be described with reference to FIG. FIG. 5 shows the configuration and functions of the monitoring control device 100 of the driving console 50. Elements common to the embodiment of FIG. 2 are denoted by the same reference numerals. Since the MMI 101 is the same as that of the embodiment of FIG. The monitoring control apparatus 100 in the embodiment of FIG. 5 has the same configuration and functions as in the embodiment of FIG. 2, but the operation authority definition temporary storage file 501 is stored in the storage device 110, and the operation authority The following two points in the determination process 115 are different.

  That is, the operation authority determination processing 115 is the same as that of the embodiment shown in FIG. 2 up to step 403, but the change of the operation authority is registered in the operation authority definition temporary storage file 501 in step 404, and step 405. After the registration / change process by the plant operator is completed, the operator of the operation console 50 is changed to a security (operation authority) administrator (step 502), and then the contents of the operation authority definition temporary storage file 501 are changed to the operation authority. The difference is that it is registered in the definition file 112 (step 503).

  The change of the operator of the driving console 50 in step 502 is executed when the security (operation authority) administrator inputs his / her ID and password via the MMI 101 of FIG. The registration process in step 503 is executed after the security (operation authority) administrator confirms the contents of the operation authority definition temporary storage file 501.

  The security (operation authority) administrator can confirm the contents of the operation authority definition temporary storage file 501 by printing using the printing device 106 or displaying the screen on the display device 103 using the MMI 101. When printing the operation authority definition temporary storage file 501 or displaying the screen, only the newly registered part or changed part is output or highlighted, etc., so that the security (operation authority) administrator is burdened. Can be reduced.

  It should be noted that step 502 and step 503 are performed after step 128, that is, after the processing of the operation console 50 by the plant operator is once finished, the operator change to the security (operation authority) administrator and the operation authority. Registration of the definition temporary storage file 501 to the operation authority definition file 112 can also be performed.

  As described above, in the embodiment of FIG. 5, the contents registered by the plant operator are not immediately registered in the operation authority definition file 112 but are registered after confirmation by the security (operation authority) administrator. Accordingly, since it can be checked that there is no error in the registration / change of the operation authority, the security management becomes more reliable, which is in line with the actual operation of the process monitoring control system.

  The operation of the plant operator described here is an operation in the operation authority simulation mode. Therefore, as in the embodiment of FIG. 2, the plant is not actually controlled or the result is not output in the execution of the operation in step 125 or the output of the operation result in step 126.

  As described above, in the present invention, since the plant operator sets the operation authority in the operation authority simulation mode, it is easy to visually understand and easily register and change the operation authority in the same procedure as the actual operation. is there. In addition, a security (operation authority) administrator can perform the above-described operation authority registration / change operation as a plant operator in the operation authority simulation mode.

  In the above-described embodiment, the plant operator first operates the operation console 50, and determines whether or not there is an operation authority for the operation (step 123). The determination of the presence / absence of the operation authority can be performed in advance, for example, during the operator authentication process in step 121. In this case, in the normal mode, the plant operator can select only an operation with an operation authority, and cannot execute or select an operation without an authority. In the operation authority simulation mode, selection and operation can be performed regardless of the operation authority determination result, and the operation authority can be registered and changed as described in the above example.
