Description

  The present invention relates to a plant equipment state management method and a plant equipment state management system, and in particular, a plant equipment state management suitable for managing the state of a plant equipment such as a power plant of a nuclear power plant and a thermal power plant and a chemical plant. The present invention relates to a method and a plant equipment state management system.

  Conventionally, in a plant such as a chemical plant and a power plant, a system diagram of the plant is displayed on a screen of an operation monitoring device, and a state such as an opening degree of a valve provided in the plant is displayed. However, only the open / close state of the motor-operated valve that can be measured online is displayed in the display on the operation monitoring device of the open / close state of the valve. As for the manual valves that occupy more than half of the valves provided in the plant, the open / close state is not displayed in real time because the open / close state is not confirmed online.

  In particular, in a nuclear power plant, it is necessary to start the plant safely after confirming that the system is in a predetermined state after the periodic inspection is completed. The confirmation work of the system state is mainly to confirm the open / closed state of the valve in the system. The electric valve is provided with a limit switch, and the open / close state of the electric valve can be measured by this limit switch. The output signal indicating the open / close state of the motor operated valve from the limit switch is directly (or via the control device) taken into the process computer, and the motor control valve opening / closing information based on the output signal is displayed on the display device. For this reason, the open / close state of the electric valve can be confirmed in the central control room.

  However, in a nuclear power plant, a manual valve accounts for about 70% of valves provided in the plant that need to confirm an open / closed state before starting the nuclear power plant. These manual valves are not provided with limit switches, and inspectors often visit the site where the plant is installed to check the open / closed state of these manual valves. It takes a lot of time to confirm the open / closed state of the manual valve before the start-up, and it is strongly desired to reduce the confirmation work itself and human error generated in the confirmation work.

  Japanese Patent Application Laid-Open No. 9-44231 describes a system that manages the open / closed state of valves provided in a plant. In this management system, the valve state data read from the valve state database is displayed on the screen of the operation monitoring device, and the instruction sheet creation means creates the instruction sheet based on the valve state data selected by the operator and Write the instruction issuance status in the management means. The instruction reading means reads the change instruction written by the operator who operated the valve after the operation of the valve into the open / closed state of the valve with the reader, and the result of the valve operation according to the change instruction and the data from the issuing status management means are unified. If it matches, the information indicating the valve open / close state in the valve state database is updated based on the valve state data after the valve operation.

JP-A-9-44231

  Because the limit valve is not attached to the manual valve, the operator checks the open / closed state of the manual valve by visiting the site where the manual valve is installed. ing.

  By registering the valve open / closed state in the valve state database as shown in Japanese Patent Laid-Open No. 9-44231, the valve open / closed state registered in the valve state database can be displayed on the display device. The state can be managed. However, in Japanese Patent Laid-Open No. 9-44231, an instruction for valve operation to an operator is given by an instruction sheet, and the state of the valve after the valve operation performed by the worker at the site is described in the change instruction sheet. Send instructions to the central control room operator. The operator checks whether the valve open / close state after the valve operation described in the change instruction matches the data from the issuing status management means, and if they match, the valve open / close state in the valve state database Is updated based on the valve state data after the valve operation. In Japanese Patent Application Laid-Open No. 9-44231, there is a possibility that an input error occurs when an operation result is described on paper for a valve, for example, a manual valve, and an input error occurs when the operation result is input to a maintenance console. .

  An object of the present invention is to provide a plant equipment state management method and a plant equipment state management system capable of improving the accuracy of information indicating the open / close state of a manual valve provided in a plant.

The feature of the present invention that achieves the above-mentioned object is that the first information indicating the open / closed state after the operation of the manual valve to be operated provided in the piping of the plant is input to the portable terminal, and the plant equipment state management device In the portable terminal, it is determined whether the second information indicating the open / closed state of the manual valve, which is included in the work instruction information input from the device state storage device to the portable terminal and is preset, matches the first information. When the information matches the second information, the first information is input from the portable terminal to the plant equipment state management device together with the fourth information indicating the state in the pipe provided with the manual valve. The fourth information is transmitted and stored in the device state storage device of the plant device state management device , and the plant device state management device creates display information based on the input first information.

Since it is determined whether or not the first information and the second information match, it is possible to prevent a human error when inputting the first information to the portable terminal, and it is provided in a plant used for creating display information. The accuracy of the information indicating the open / closed state of the manual valve can be improved. Furthermore, information indicating the state in the pipe can be displayed on the display screen of the portable terminal as necessary, and the worker can know the state in the pipe.

  ADVANTAGE OF THE INVENTION According to this invention, the precision of the information which shows the opening / closing state of the manual valve provided in the plant can be improved.

  The plant equipment state management method of the present embodiment performed using the plant equipment state management system 21 will be described in detail below.

  The worker 20 goes to a site such as a reactor building and a turbine building in order to open and close the manual valve 17 provided in the nuclear power plant with the portable terminal 16 and performs valve operation work. The portable terminal 16 further displays “touch”, “record list”, “device list”, “download”, “menu”, “cancel”, and “OK” on the display screen 16A. Since the work at the site places a heavy burden on the operator 20, the portable terminal 16 does not require a key input operation, and as described above, data input, output, and readout are performed by the touch unit displayed on the display screen 16A. Can be done. Each touch part of the “record list” and “device list” displayed on the display screen 16A is displayed when the operator touches these touch parts when he / she wants to see each information of the record list and the device list. It is displayed on the display screen 16A. Specifically, for example, a system is selected by a “menu” operation, and a touch operation of “record list” and “device list” is performed on the system.

  The portable terminal 16 executes the process shown in FIG. First, work instruction information is input (step SA1). When the operator 20 presses the “download” touch part of the mobile terminal 16, work instruction information (permission number, system number, system name, equipment) read from the equipment state database 36 of the plant equipment state management device 9. Number, device name, device state, operator name) are input to the portable terminal 16. The inputted work instruction information is stored in an internal memory (not shown) of the portable terminal 16. The equipment number is a number assigned to the manual valve provided in the nuclear power plant, and the equipment name is a name for the corresponding manual valve. The equipment state is the open / close state of the manual valve. The operator name is the name of the operator who performed the operation of opening or closing the manual valve. The system name is the name of the piping system in which the manual valve is installed. The work instruction information is transmitted from the plant equipment state management device 9 to the mobile terminal 16 via the local wired LAN 12, the communication station 11, the local wired LAN 15 and the access point 14, and the operation of the transmission / reception processing unit 44 of the mobile terminal 16 is performed. Thus, the data is taken into the mobile terminal 16 from the communication interface 43 of the mobile terminal 16. The transmission / reception processing unit 44 receives information from the outside at the mobile terminal 16 when the “download” touch unit is pressed, and externally transmits information from the mobile terminal 16 when the “upload” touch unit is pressed. Send information to. The display screen 16A of the portable terminal 16 displays work instruction information.

  When the worker 20 comes to the manual valve 17 to be worked, the worker 20 points the portable terminal 16 toward the RFID tag 18 attached to the manual valve 17. Device ID information is input from the RFID tag (step SA2). The mobile terminal 16 reads the device ID information stored in the RFID tag 18 of the manual valve 17, that is, the ID information of the manual valve 17. The ID information of the manual valve 17 is taken into the portable terminal 16 from the communication interface 43 and stored in the internal memory. It is confirmed whether or not the device to which the ID information is input is a work target device (step SA3). The device identification processing unit 46 compares the device number included in the input work instruction information with the device ID information (ID information of the manual valve 17) stored in the RFID tag 18 read by the portable terminal 16, and the manual valve It is confirmed whether 17 is the work target device instructed by the work instruction information. When the device identification processing unit 46 recognizes that the ID information of the manual valve 17 is the device number included in the work instruction information, the device identification processing unit 46 displays on the display screen 16A that the manual valve 17 is a work target device.

  The work instruction information displayed on the display screen 16A of the portable terminal 16 is viewed by the worker 20 so that the manual valve 17 is “fully closed (or closed)” or “fully opened (open)” according to the work instruction information. To do.

  The “isolation state” shown in FIG. 7 and FIG. 8 indicates that when work such as maintenance or replacement of a valve occurs, an isolation work is performed on a system including the valve during maintenance inspection when the nuclear power plant is stopped ( This means that the isolation operation is performed, which is performed by closing the valve for isolation or opening the valve for draining). The state that is not in the isolation state is the normal state.

  The operation result of the target device is input (step SA4). After the operation of the manual valve 17, when the operator 20 presses the “download” and “record list” touch sections of the portable terminal 16, the device state stored in the device state database 36 of the plant device state management device 9. Data is read out, taken into the portable terminal 16 via the local wired LAN 15 and the access point 14 and stored in the internal memory. The captured device status data is displayed on the display screen 16A. An example of the device status data displayed on the display screen 16A is shown in FIG. Since the manual valve 17 is operated in the fully closed state as the “isolation state” at the time of periodic inspection of the nuclear power plant and the state is confirmed, the operator 20 operates the guide button 22 to enter the device number column of the manual valve 17. The frame of the isolation state is designated with, and “fully closed” is input with the guide button 22.

  The operation result is compared with the work instruction content (step SA5). The work result confirmation processing unit 47 includes information on the device state (for example, the open / close state of the manual valve 17) after the operation of the work target device input in step SA4 and the device state included in the work instruction information input in step SA1. The information (work instruction content) is compared, and it is determined whether the input device state (for example, the open / close state of the manual valve 17) of the work target device matches the work instruction content. When the device state after the operation of the work target device (for example, the open / close state of the manual valve 17) does not match the work instruction content, that is, in step SA4, the open / close state of the manual valve 17 after the manual valve 17 is operated. When the information is erroneously input as fully open, unlike the work instruction content (manual valve 17 is fully closed), an alarm is output (step SA8). When this alarm is output, the processes in steps SA3 to SA5 are repeated.

  When the device state of the work target device (for example, the fully closed state of the manual valve 17) input in the comparison in step SA5 matches the work instruction content, the worker 20 is in the pipe to which the manual valve 17 is attached. Check the status. To check the condition in this pipe, for example, if the upstream manual valve is closed to vent and the vent valve (manual valve) is opened and water can be vented, it is determined that there is no water, the upstream valve is open and the vent valve is open. If it is closed, it is determined by judging that there is water. Information indicating the confirmed state in the pipe is input (step SA6). For example, the worker 20 inputs information indicating the state in the pipe in which the manual valve 17 is installed to the portable terminal 16 using the guide button in association with the manual valve 17.

  Information indicating the operation result of the work target device and information indicating a state in the pipe provided with the work target device are output to the plant device state management device (step SA7). The worker 20 presses the “upload” touch part of the mobile terminal 16. Information indicating the operation result (for example, opening / closing state of the manual valve 17) of the work target device input in Step SA4 and the state in the pipe provided with the work target device (for example, the manual valve 17) input in Step SA6 The device status data of the work target device (for example, the manual valve 17) including the information indicating that is transmitted from the portable terminal 16 to the nearby access point 14 by radio. The equipment state data is transmitted to the plant equipment state management apparatus 9 via the local wired LAN 15, the communication station 11, and the local wired LAN 12, and stored in the equipment state database 36.

  The GUI processing unit 45 of the mobile terminal 16 displays each display information of the record list list and the device list list when the worker touches each touch part of the “record list” and “device list” displayed on the display screen 16A. The display information is created and displayed on the display screen 16A.

  By the above, operation with respect to one manual valve 17, the input of the relevant information to the portable terminal 16, and transmission of the input information to the plant equipment state management apparatus 9 are completed. The worker 20 operates the mobile terminal 16 to input work instruction information for another work target device (for example, another manual valve) in Step SA1 to the mobile terminal 16. The worker 20 moves to the installation position of another work target device (for example, another manual valve), performs necessary operations regarding the other work target device, and confirms the state in the pipe, to the portable terminal 16. Enter the necessary information. The portable terminal 16 executes the processes of steps SA1 to SA8 shown in FIG.

  In this way, the worker 20 checks the state of the work target device with respect to the work target devices (for example, manual valves) of the three device numbers (a) to (c) shown in FIG. When the valve is not in the open / closed state (fully closed state) of the isolation state during the maintenance inspection in the periodic inspection period of the nuclear power plant, based on the work instruction information displayed on the display screen 16A of the mobile terminal 16 Suppose that the manual valve is fully closed. The operator inputs the manual valve check result after the operation to the portable terminal 16 and transmits it to the plant equipment state management device 9. In step SA7, the respective device state data for the work target devices (for example, manual valves) of the three device numbers (a) to (c) shown in FIG. 7 are transmitted to the plant device state management device 9. For this reason, each apparatus state data with respect to the work object apparatus (for example, manual valve) of the three apparatus numbers (a) to (c) shown in FIG. 7 is input to the plant apparatus state management apparatus 9. The device status data of the work target devices (for example, manual valves) of the three device numbers (a) to (c) are the isolation states indicating the device states of the respective work target devices (for example, the manual valves). Information (refer to FIG. 7) and information (refer to FIG. 8) indicating a state in a pipe provided with a work target device (for example, a manual valve) are included.

  Next, the plant equipment state management method of a present Example is demonstrated below. In particular, processing executed using the plant equipment state management device 9 will be described with reference to FIGS. 9 and 10. First, the transmission of information between the portable terminal 16 and the plant equipment state management device 9 when the plant equipment state management method of the present embodiment is carried out will be described with reference to FIG.

  Work instruction information is transmitted to the portable terminal (step SB1). When the “download” touch part is pressed on the portable terminal 16 and the work instruction information is requested to be transmitted, the work instruction information creating part 32 of the plant equipment state management device 9 performs the work instruction information (permission number, system number, System name, device number, device name, device status, operator name) are read from the device status database 36 and transmitted from the communication interface 31 to the portable terminal 16. This work instruction information is input to the portable terminal 16 in step SA1 described above.

  The device status data output from the portable terminal is input (step SB2). Information indicating the operation result of the work target device (for example, the fully closed state of the manual valve 17) output from the portable terminal 16 in step SA7 and the work target device (for example, the manual valve 17) input in step SA6 are provided. Device state data of the work target device (for example, the manual valve 17) including information indicating the state in the pipe is taken into the plant device state management device 9 from the communication interface 31 and stored in the device state database 36. .

  The input device status data is compared with the work instruction information (step SB3). For example, it is assumed that information indicating the operation result of the work target device (for example, the fully closed state of the manual valve 17) included in the device state data is included. The work confirmation processing unit 33 compares the device state data input in step SB2 with the work instruction information output in step SB1, and information indicating the operation result of the work target device included in the device state data is included in the work instruction information. It is determined whether it matches the device status information. When the work confirmation processing unit 33 determines that both pieces of information match, that is, for example, the manual valve 17 whose information indicating the fully closed state of the manual valve 17 is the work instruction content matches the fully closed state. When it is determined that the process is performed, the process of step SB4 is executed. When the work confirmation processing unit 33 determines that the two pieces of information do not coincide with each other, that is, information indicating the fully opened state, which is information on the manual state of the manual valve 17, is the work instruction content. When it is determined that the manual valve 17 is different from the fully closed state, alarm information is transmitted to the portable terminal (step SB5). The alarm information created in the work confirmation processing unit 33 in step SB5 is input to the portable terminal 16 via the local wired LAN 12, the communication station 11, the local wired LAN 15, and the access point 14 present near the terminal 16 at the present time. The When the work confirmation processing unit 33 outputs the alarm information, the information indicating the operation result of the work target device (for example, the fully closed state of the manual valve 17) does not match the device state information included in the work instruction information. Information indicating this and the device number of the work target device are output together.

  The mobile terminal 16 that has input the alarm information issues an alarm, and information indicating the operation result of the work target device (for example, the fully opened state of the manual valve 17) does not match the device state information included in the work instruction information. And the device number of the work target device are displayed on the display screen 16A. When an alarm is issued from the mobile terminal 16, the worker 20 views information indicating that the information on the display screen 16 </ b> A does not match and the device number. The worker 20 performs a fully closing operation on the work target device (for example, the manual valve 17) having the device number. After that, each of the processes in steps SA3 to SA5 and SA7 shown in FIG. 6 is performed in the mobile terminal 16, and includes the information indicating the operation result of the work target device (for example, the fully closed state of the manual valve 17) executed again. The state data is output from the portable terminal 16 and input to the plant equipment state management device 9. In the work confirmation processing unit 33, information indicating the operation result of the work target device (for example, the fully closed state of the manual valve 17) included in the newly input device state data includes device state information ( It is determined whether it matches the work instruction content). When it is determined that both pieces of information match, the process of step SB4 is executed.

  The input device status data is stored in the device status database (step SB4). When the work confirmation processing unit 33 determines that both pieces of information match in the process of step SB3, the device status data transmitted from the portable terminal 16 in step SB2 (for example, (a ) To (c) are stored in the device state database 36 with respect to the work target devices (for example, manual valves) of the device numbers of the three device numbers.

  Thereafter, the mobile terminal is notified that normal device state data has been received (step SB6). After the device status data is stored in the device status database 36, the work confirmation processing unit 33 uses the communication interface to receive information indicating that normal device status data related to the work target device (for example, the manual valve 17) has been received. 31 to the mobile terminal 16. The reception information output from the plant equipment state management device 9 is displayed on the display screen 16 </ b> A of the mobile terminal 16. The worker 20 who has seen the received information can know that the normal equipment state data for the manual valve 17 has been received by the plant equipment state management apparatus 9.

  Device state data from the process computer is stored in the device state database (step SB7). The process computer 8 stores information indicating the open / closed states of all motor-operated valves provided in the nuclear power plant, such as the bypass valves 6A and 7A executed by the control devices such as the control devices 6 and 7. For example, when the opening degree of the bypass valve 6A is controlled by the control device 6, the information indicating the open / closed state of these motorized valves is detected by the limit switch 6c provided in the bypass valve 6A. Is done. Information indicating the open / closed state of the bypass valve 6A detected by the limit switch 6c (for example, device state data for the electric valve (XX bypass valve) of one device number (d) shown in FIG. 7) is controlled. The data is output from the apparatus 6 to the process computer 8 and stored in the internal memory of the process computer 8. Information indicating the open / close state of all the motorized valves stored in the internal memory of the process computer 8 is input to the plant equipment state management device 9 and stored in the equipment state database 36 by the work confirmation processing unit 33.

  The equipment state management unit 34 of the plant equipment state management apparatus 9 uses the equipment state data input from the portable terminal 16 in step SA7 and the information indicating the open / close state of the motor operated valve input from the process computer 8 in step SB7. And the management information shown in FIG. 8 is created.

  Next, creation of display information using equipment state data input from the portable terminal 16 of the plant equipment state management method of the present embodiment will be described with reference to FIG.

  In order to create the display information of the plant state, the plant system information is fetched from the maintenance console (step SC1). After the process of step SB6 is completed, the system state display information creation unit 35 of the plant equipment state management device 9 sends a system information request signal for requesting system information necessary for creating the display information of the plant state to the maintenance console 10. Output to. When the maintenance console 10 receives a system information request signal from the plant equipment state management device 9, the maintenance console 10 reads the requested system information from the equipment management database 42 and inputs it to the plant equipment state management device 9.

  Pipe instrumentation diagram information of a system provided with a target device for creating display information is extracted (step SC1). The system state display information creation unit 35 is provided with a target device for creating display information among the system information captured from the device management database 42 of the maintenance console 10 in the process of step SC1 after the process of step SC1 is completed. Pipe instrumentation diagram information of the system, that is, a pipe provided with each manual valve having the device numbers (a) to (c) shown in FIGS. The piping instrumentation diagram information of each piping system, which is a system provided with the motor-operated valve having the device number (d) shown in FIGS. 7 and 8, input from the system and the process computer 8, is extracted.

  Display information of piping instrumentation diagram information including device status data of the target device for which display information is to be created is created (step SC3). The system status display information creation unit 35 adds the device status data of the target device for creating display information to the piping instrumentation diagram information of the target device for creating display information, and the device status of the target device for creating display information Create display information of piping instrumentation diagram information including data. Specifically, the system state display information creation unit 35 creates each manual valve (display information created) input from the mobile terminal 16 and having the device numbers (a) to (c) shown in FIGS.
