Description

  The present invention relates to an alarm recording system for recording an alarm displayed on a control panel in a power plant.

  Conventionally, in a control room of a power plant, a plurality of control panels for plant operation are installed for each facility. A large number of alarm windows on which alarm names are described are provided on the surface of the control panel. These alarm windows are provided corresponding to various detectors (for example, thermometers, flow meters, etc.) provided in the field facilities, and the values detected by the detectors in the control panel are abnormal. When it is determined that the alarm window is lit, the operator (operator) is informed of an abnormality or the like by a buzzer sound.

  Specifically, when an abnormality occurs in the power plant equipment, the corresponding alarm window blinks, and at the same time, an alarm notification buzzer installed on the control panel sounds to notify the operator of the abnormality. . The operator visually confirms the alarm name of the flashing alarm window, and then presses an alarm confirmation button installed for each control panel to determine whether the alarm is ongoing. If the cause of the alarm is ongoing, the alarm window switches from flashing to staying lit, and the buzzer sound stops.

  The alarm window that no longer has a cause for alarm is switched to slow blinking and the buzzer for turning off the alarm sounds. In this state, when the operator presses an alarm reset button installed for each control panel, the alarm is turned off and the buzzer sound is also stopped.

  By the way, conventionally, when an alarm is issued, an operator keeps it as a record by manually writing the alarm name and the alarm time on a recording sheet.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is a block diagram showing an outline of an alarm system in the first embodiment of the present invention.
[System configuration]
The alarm system 1 is provided in a central management room and includes a plurality of control panels 10, an electronic computer 20, a printer 30, and a display 40.

  The control panel 10 includes a CPU 100, an alarm display unit 102, an alarm buzzer 104, an alarm confirmation button 106, an alarm reset button 108, an input / output unit 110, and a storage unit 112. A plurality of detectors 200 are connected to the control panel 10. Examples of the plurality of detectors 200 include a radiometer, a thermometer, an air flow meter, a pressure gauge, a water level gauge, a water temperature gauge, and the like installed at a predetermined location of a power plant facility. Further, the plurality of control panels 10 are classified according to the systems, and the detectors 200 corresponding to the systems of the control panels 10 are connected.

  The electronic computer 20 includes an arithmetic device (not shown) and a storage device 22, and the electronic computer 20 and the control panel 10 are connected so as to be able to transmit and receive. Further, the electronic computer 20 performs processing for creating print information based on the information transmitted from the control panel 10 and causing the printer 30 to print it out, or creating display information and displaying it on the display 40.

[Control panel configuration]
Next, the control panel 10 will be described.
The CPU 100 controls the entire control panel 10.
The alarm display unit 102 includes a plurality of alarm windows 12 as shown in FIG. 2, and the plurality of alarm windows 12 (see FIG. 2) can emit light such as lighting, extinguishing, and flashing (not shown). )). Each of the plurality of alarm windows 12 is marked with a unique number and an alarm name. In the example shown in FIG. 2, the numbers “1A”, “1B”, “1C”,..., “6F”, “6G” are unique numbers, and “□ ○ △ high temperature”, “ The text information “□□ △ Temperature abnormally high”, “□ ● ▲ High temperature”,..., “● ▽ ▲ Temperature abnormally high”, “● ▼ Low temperature” is the alarm name. Further, the alarm window 12 and the detector 200 correspond one-to-one, and the CPU 100 performs light emission control of the alarm window 12 corresponding to the detector 200 based on the detection result of the detector 200. Specifically, when the CPU 100 determines that an abnormality has occurred in the facility based on the detection result of the detector 200, the alarm window 12 is caused to emit light and notify the occurrence of the abnormality.

  The alarm buzzer 104 sounds when any one of the alarm windows 12 in the alarm display unit 102 emits light and when the emitted alarm window 12 is turned off.

  The alarm confirmation button 106 holds the light emission state of the alarm window 12 when pressed when any of the alarm windows 12 in the alarm display unit 102 emits light.

  The alarm reset button 108 is a button for turning off the alarm display unit 102 and stopping the alarm buzzer 104 from sounding.

  The input / output unit 110 is connected to an external device and performs transmission / reception with the external device. In addition, the storage unit 112 includes a detection result storage area that stores the state of each detector 200. When the CPU 100 determines that there is an abnormality based on the detection result of the detector 200, the storage area corresponding to the detector 200 of the equipment that is determined to be abnormal in the detection result storage area of the storage unit 112. In addition, data indicating an abnormality is stored. On the other hand, if the CPU 100 determines that the state has returned to normal after determining that it is abnormal based on the detection result of the detector 200, the CPU 100 stores it in the storage area corresponding to the detector 200 in the detection result storage area. Clear the data indicating that it is abnormal. Thus, the CPU 100 of the control panel 10 functions as an abnormality determination unit. Here, since the detector 200 and the alarm window 12 have a one-to-one correspondence, the storage area corresponding to the detector 200 in the detection result storage area of the storage unit 112 and the alarm window 12 have a one-to-one correspondence. It corresponds. Therefore, in the detection result storage area of the storage unit 112, the alarm window 12 corresponding to the storage area in which data indicating abnormality is stored is blinking or lit. For this reason, the CPU 100 can grasp the lighting status of the plurality of alarm windows 12 by referring to the detection result storage area of the storage unit 112.

Next, alarm display on the control panel 10 will be described.
The CPU 100 of the control panel 10 constantly monitors the state of the detector 200. If the CPU 100 determines that an abnormality has occurred based on the detection result of the detector 200, the CPU 100 stores that fact in the detection result storage area of the storage unit 112. Further, the CPU 100 performs control to cause the alarm window 12 corresponding to the detector 200 to blink and to drive the alarm buzzer 104 to sound an alarm generating buzzer sound. Thus, the CPU 100 of the control panel 10 functions as an alarm window lighting control unit and an alarm window lighting control unit.

  In addition, when the CPU 100 determines that the detection result is abnormal based on the detection result of the detector 200 or when the detection result is determined to have been switched from abnormal to normal, the CPU 100 receives the alarm name information from the input / output unit 110 and the computer 20. Alarm name information transmission processing to be transmitted to is performed. This alarm name information transmission process will be described later. In other words, the alarm name information is transmitted from the control panel 10 to the electronic computer 20 when an alarm is issued and when the alarm is canceled.

  The computer 20 that has received the alarm name information identifies the control panel 10 that has transmitted the alarm name information, creates print information based on the specific information and the alarm name information, and executes a print recording process for causing the printer 30 to print the print information. To do. This print recording process will be described later.

  The operator visually confirms the alarm name of the alarm window 12 blinking and then presses the alarm confirmation button 106 installed on the control panel 10. When the CPU 100 detects that the alarm confirmation button 106 has been pressed, the CPU 100 switches the alarm window 12 from blinking to remain lit and performs control to stop the buzzer sound. Thereby, the alarm window 12 corresponding to the detector 200 in which the abnormality has not been resolved when the operator presses the alarm confirmation button 106 is turned on.

  In addition, when the detection result of the detector 200 is switched from abnormal to normal, the CPU 100 switches the display of the alarm window 12 to slowly blinking and causes the alarm buzzer 104 to sound an alarm extinguishing buzzer sound. If the CPU 100 detects that the alarm reset button 108 has been pressed while the alarm buzzer is sounding, the CPU 100 turns off the alarm window 12 that is lit slowly and emits a buzzer sound. Stop.

[Alarm name information transmission processing]
Next, alarm name information transmission processing will be described.
When the CPU 100 determines that the detection result of the detector 200 is abnormal, or when it is determined that the detection result of the detector 200 has switched from abnormal to normal, the alarm name corresponding to the alarm information notified by the alarm window Process to create information. Here, the alarm name information is generated corresponding to the alarm name information generated for the detector 200 whose detection result is switched from normal to abnormal and the detector 200 in which the abnormal state continues. There are three types of continuation alarm name information and release alarm name information created for the detector 200 whose detection result has been switched from abnormal to normal.

  Specifically, when the CPU 100 detects the detector 200 whose detection result has been switched from normal to abnormal, the CPU 100 adds information indicating that the detection has been switched from normal to abnormal to the alarm name corresponding to the detector 200. The alarm warning name information is created. Further, in the detectors 200 other than the detector 200 corresponding to the alerting alarm name information, continuous alarm name information is created by referring to and extracting the data in the storage area for abnormal detection results. Then, the CPU 100 performs a process of transmitting the warning alarm name information and the continuation alarm name information to the electronic computer 20.

  Further, when the CPU 100 detects the detector 200 whose detection result has been switched from abnormal to normal, the CPU 100 adds the information indicating that the detection has been switched from abnormal to normal to the alarm name corresponding to the detector 200. Create name information. Further, in the detectors 200 other than the detector 200 corresponding to the release alarm name information, continuous alarm name information is created by referring to and extracting the data in the storage area that has an abnormal detection result. And CPU100 performs the process which transmits cancellation | release warning name information and continuation warning name information to the electronic computer 20. FIG. Here, the computer 20 that has received the alarm name information discriminates the information added to the individual alarm names, so that the alarm names are among the alert alarm name information, the continuous alarm name information, and the release alarm name information. It is possible to identify which information is classified.

  For example, in the alarm window 12 shown in FIG. 2, the CPU 100 of the control panel 10 has already determined that the detection result of the detector 200 corresponding to the 5C and 5D alarm window 12 is abnormal, When it is determined that the detection result is abnormal in the order of the detector 200 corresponding to the alarm windows 12 of 2C, 2B, and 2A, the alarm window 12 is displayed on the alarm display unit 102 of the control panel 10 as shown in FIG. Flashes.

  In this case, since the CPU 100 of the control panel 10 first determines that the detection result of the detector 200 corresponding to the 2C alarm window 12 is abnormal, the alarm is issued based on the alarm name corresponding to the 2C alarm window 12. A process of creating alarm name information, creating continuous alarm name information based on the detector 200 alarm name corresponding to the 5C and 5D alarm windows 12, and transmitting these two pieces of information to the electronic computer 20 as alarm name information. Do. Next, since the CPU 100 of the control panel 10 first determines that the detection result of the detector 200 corresponding to the 2B alarm window 12 is abnormal, the alarm is issued based on the alarm name corresponding to the 2B alarm window 12. The alarm name information is created, the continuous alarm name information is created based on the detector 200 alarm name corresponding to the 2C, 5C and 5D alarm windows 12, and the two pieces of information are transmitted to the computer 20 as the alarm name information. Process. Next, since the CPU 100 of the control panel 10 first determines that the detection result of the detector 200 corresponding to the 2A alarm window 12 is abnormal, the alarm is issued based on the alarm name corresponding to the 2A alarm window 12. Create alarm name information, create continuous alarm name information based on the detector 200 alarm name corresponding to the alarm window 12 of 2B, 2C, 5C, and 5D, and send these two information as alarm name information to the computer 20 Process to send. Therefore, the printer 30 prints out three recording sheets on which the lighting state of the alarm window 12 is recorded.

  When the CPU 100 of the control panel 10 determines that the detection result of the detector 200 corresponding to 5C in FIG. 2 has become normal due to abnormality, the alarm window 12 shown in FIG. The 5C alarm window 12 blinks slowly and then turns off.

  In this case, since the CPU 100 of the control panel 10 determines that the detection result of the detector 200 corresponding to the 5C alarm window 12 has become normal from the abnormality, the release alarm is based on the alarm name corresponding to the 5C alarm window 12. Create name information, create continuous alarm name information based on the detector 200 alarm name corresponding to the alarm windows 12 of 2A, 2B, 2C and 5D, and send these two pieces of information to the computer 20 as alarm name information Perform the process.

  Next, the print recording process will be described with reference to FIG.

  When the alarm name information is transmitted from the control panel 10 ((1) in FIG. 3) and the electronic computer 20 receives the alarm name information, the electronic computer 20 analyzes the received alarm name information and converts it into the alarm name information. The included alarm names are accumulated and stored together with the received time in the storage device 22 provided in the electronic computer 20 ((2) in FIG. 3). Then, the electronic computer 20 creates print information based on the alarm name and reception time stored in the storage device 22 and information specifying the control panel 10 that transmitted the alarm name information, and transmits the print information to the printer 30 ( (3) in FIG. The printer 30 that has received the print information prints the print information on a recording sheet. Further, based on the operator's instruction input, the electronic computer 20 creates display information based on the alarm name and reception time stored in the storage device 22 and outputs the display information on the display 40 ((( 4)). Since the CPU 100 transmits the alarm name information immediately after detecting the change in the detection result of the detector 200, the time when the electronic computer 20 receives the alarm name information is set as the alarm issue time or the release time. Can be considered.

  FIG. 4 is an explanatory diagram showing the contents of the recording paper printed out from the printer. As shown in FIG. 4, the content of the recording paper is information that specifies the control panel 10 that has transmitted the alarm alert information as a title in the print format so that the arrangement is the same as that of the alarm window 12 shown in FIG. Is inserted, various alarm names are inserted, and the reception time is inserted as the recording time. In addition, a display frame corresponding to the alarm window 12 for the warning alarm name information, a display frame corresponding to the alarm window 12 for the continuous alarm name information, a display frame corresponding to the alarm window 12 for the release alarm name information, and an alarm target The background colors of the display frames corresponding to the alarm window 12 are different. For this reason, when you look at the recording paper, the name of the alarm that has been issued, the name of the alarm that has continued, and the name of the alarm that has been released are now distinguished by the background color of the display frame, making it easy to check. It becomes possible.

  4 is a state in which the CPU 100 of the control panel 10 has already determined that the detection result of the detector 200 corresponding to the 5C and 5D alarm windows 12 in FIG. 2 is abnormal. Further, for example, in the order of the detector 200 corresponding to the 2C, 2B, and 2A alarm windows 12, when the detection result is determined to be abnormal, printing is performed based on the alarm name information corresponding to the 2A alarm window 12. It has been done.

  As shown in FIG. 4, the background of the display frame corresponding to the alarm window 12 of 2A is different from the background of the other display frames. Here, since the time when the electronic computer 20 received the alarm name information is printed as the recording date and time on the recording paper, the equipment with the alarm name of 2A becomes abnormal and the alarm window 12 emits light at this recording date and time. Can be determined from the recording paper.

  Also, before the print output shown in FIG. 4 is executed by the printer 30, the print output on the recording paper based on the alarm name information corresponding to the alarm windows 12 of 2C and 2B is executed. For this reason, it is possible to grasp the lighting state of the alarm window 12 by filing the recording paper in time series.

  According to the first embodiment configured as described above, when the control panel 10 determines that an abnormality has occurred in the facility, the control panel 10 transmits alarm information (alarm name information) to the computer. Get name information) time. Then, the computer creates print information based on the alarm information (alarm name information), the reception time, and information specifying the control panel 10 that has transmitted the alarm name information, and outputs the print information to the printer 30. From, the recording paper on which the alarm name and the reception time are printed is output. Thus, when an abnormality occurs in the facility, the printer 30 outputs a recording sheet on which the alarm information and the reception time are printed, so it is possible to accurately grasp the alarm occurrence status.

  In addition, since the names and times of alarms that have occurred in the past are accumulated and recorded in the storage device 22, it is possible to browse alarm information and a history of reception times. This makes it possible to analyze the tendency of warnings. Furthermore, since the alarm information stored in the storage device 22 can be displayed on the display 40, it can be easily confirmed without printing out on the recording paper.

(3)). The printer 30 that has received the print information prints out the print information on a recording sheet ((4) in FIG. 7).

  According to the third embodiment configured as described above, when the detection result of the detector 200 is switched from normal to abnormal or from abnormal to normal, the lighting state of the alarm window 12 is printed on the recording paper. When the lighting status of the alarm window 12 at a time other than the above is recorded, or when the lighting status is recorded in units of the control panel 10, the lighting status of the alarm window 12 is changed from the printer 30 by pressing the printout button 120. It is possible to output printed recording paper.

  In the third embodiment, the printout button 120 is provided in the second embodiment. However, the alarm name information at the time when the printout button 120 is provided and the printout button 120 is pressed is provided in the first embodiment. The pressing time may be transmitted to the electronic computer 20.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. For example, in the above-described embodiment, a recording sheet as shown in FIG. 4 is output, but the print format in which the alarm name and the reception time are described is not limited to that shown in FIG. For example, the storage unit 112 of the control panel 10 according to the first embodiment stores a weighting table in which the alarm name and the warning content level are associated with each other. Then, when transmitting the alarm name information to the electronic computer 20, the control panel 10 refers to the weighting table and adds weighting data to each alarm name data included in the alarm name information before transmitting. To do. In the electronic computer 20, when alarm name information is received, the warning content level of the alarm name is obtained based on the weighted data. Then, the electronic computer 20 may create print information using a print format stored in order from the highest level, and transmit the print information to the printer 30. Note that the weighting table may be stored in the storage device 22 of the electronic computer 20. In this case, the level of each alarm name is obtained by comparing each alarm name included in the alarm name information transmitted from the control panel 10 with the weighting table, and the print format is stored in order from the highest level. The print information is generated and transmitted to the printer 30. As a result, it is possible to print out the warning contents separately for each level, and classification can be easily performed.

  Similarly, a weighting table in which an alarm name and an alarm content level are associated with each other is stored in the storage unit 112 of the control panel 10 in the second and third embodiments. Then, when transmitting the alarm name information to the electronic computer 20, the control panel 10 refers to the weighting table to obtain the level of the warning content corresponding to the alarm name, and uses a print format stored in order from the highest level. Print information may be created and sent to the printer 30.

  Alternatively, the printer 30 may have a print format describing the alarm name and the reception time, and the print format may be set by the printer driver of the printer 30. As a result, the computer 20 in the first embodiment or the control panel 10 in the second and third embodiments transmits the alarm name, the reception time, and information for specifying the control panel 10 to the printer 30, and the printer 30 side. The print data is created by inserting the alarm name and the reception time into the print format prepared in advance by the printer 30. Then, the printer 30 executes print output on recording paper based on the print data. As a result, it is possible to reduce the burden on the creation of print information in the electronic computer 20 of the first embodiment or the control panel 10 of the second and third embodiments.

  In the present embodiment, the alarm name information or the print information transmitted from the plurality of control panels 10 is printed out by one printer 30. However, the present invention is not limited to this, and a plurality of printers 30 may be used. . When one printer 30 performs printing output, if the printer 30 has a sorter function for sorting and discharging recording paper, for example, the control panel 10 transmits alarm name information or printing information. At this time, the control panel 10 is attached with unique information and transmitted to the printer 30. The printer 30 controls the sorter function based on the unique information, and the alarm name information or print information transmitted from the same control panel 10 is transmitted. In this case, the recording paper may be discharged onto the same discharge tray.
