Description

  The present invention relates to a hard copy output control system in an alarm device that notifies an alarm occurrence of a power plant or the like.

  Generally, when a plant alarm or device abnormality occurs in a plant such as a power plant, this is detected depending on whether or not the process data measured in each part of the plant has deviated from a predetermined alarm set value, and an alarm window is displayed. The operator is notified of the alarm occurrence, the generating device, the alarm content, etc. by lighting and displaying on the display device.

  Such alarm processing is performed by a computer, but in a plant monitoring control system such as a power plant, whether or not the process data has deviated from the alarm set value by a control device for controlling the plant or a computer for monitoring and controlling them. Judgment is carried out.

  In recent years, the number of alarm points monitored by a computer has been increasing in order to centrally monitor alarms by a computer. For this reason, the number of alarm points collected in the alarm window is also increasing.

  On the other hand, attempts have been made to reduce the number of windows by consolidating alarm windows, and further, an alarm window-less system without this alarm window has been developed. For this reason, the importance which monitors an alarm with a display apparatus is increasing.

  The alarm screen displayed on the display device is saved as a hard copy as necessary. FIG. 24 shows a conventional hard copy output control system. The display device 1 displays screen data from the screen data output processing means 2, and the plant operator inputs a hard copy request for the displayed screen. Input is performed by operating the device 3. The input hard copy request is notified to the screen data output processing means 2 through the hard copy request processing means 4, and the screen data output processing means 2 outputs the screen data displayed on the display device 1 to the hard copy screen data output means. Output to 5. The hard copy screen data output means 5 performs hard copy output processing on the screen data from the screen data output processing means 2 and outputs it to a hard copy output device 6 such as a printer. As a result, the display screen requested by the operator to make a hard copy is output from the hard copy output device 6 as a hard copy.

  However, in the conventional hard copy output control system, the screen requested for hard copy is sequentially output from the hard copy device. In this case, the screen data requested for hard copy is output as paper, and the screen data storage medium is only paper. It becomes. When the storage medium is paper, there is a problem that it is very difficult to store screen data due to deterioration due to fading or the like.

  The present invention has been made in response to the above problems, and includes a hard copy output control system that enables screen data to be hard copied to be stored in a storage medium other than paper, or an alarm device equipped with the hard copy output control system. The purpose is to provide.

  That is, the hard copy output control system according to the first aspect of the present invention includes means for storing screen data being displayed on the display device in a storage memory in response to a hard copy request from an operator of the plant operation, and a hard copy confirmation from the operator. A means to display a hard copy request confirmation screen showing the saved contents of the storage memory upon request, and a hard copy output request of the hard copy screen selected by the operator from the hard copy request confirmation screen, and respond from the storage memory Means for taking out the hard copy screen data to be output and outputting it to a hard copy output device.

  A hard copy output control system according to a second aspect of the present invention is the hard copy output control system according to the first aspect, wherein the hard copy output control system accepts a hard copy save request for the hard copy screen selected by the operator from the hard copy request confirmation screen. The apparatus further comprises means for taking out the corresponding hard copy screen data from the storage memory and storing it in the storage device.

  According to the first and second aspects of the present invention, the screen requested for hard copy can be confirmed and output as a hard copy or stored in a storage device. Thereby, since it can preserve | save in storage media other than paper, degradation of hard copy screen data can be prevented.

  According to the present invention, the screen requested for hard copy can be output as a hard copy or saved in a storage device, whereby the hard copy screen data can be saved in a storage medium other than paper. Long-term storage of copy screen data can be enabled.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a first embodiment of the present invention.

The priority determination switching means 13 inputs signals indicating normality / abnormality of each of the n alarm processing computers corresponding to the alarm creation means 12, and the priority processing means 27 has the highest priority among normal computers. Determine the high calculator, ie the alarm creation means 12. The switching means 8 of the priority determination switching means 13 sends a connection signal to the alarm processing computer (alarm creating means 12) determined by the priority processing means 27 to execute alarm processing.

  When the alarm creating unit 12 receives the connection signal from the priority determination switching unit 13, the alarm creating unit 12 inputs the process data from the plant 11 through the plant input unit 21. The input process data is compared with the alarm set value of the corresponding input point taken out from the alarm set value table 22 by the alarm set value input means in the alarm determination means 24, and input when the alarm set value deviates. The point is determined as an alarm. Next, the alarm creating unit 12 creates alarm information based on the determination result of the alarm determining unit 24, the alarm set value used for the determination, and the process data by the alarm information generating unit 25, and the result is output to the alarm output processing unit 26.

  FIG. 13 shows a fourth embodiment of the present invention. The alarm device of this embodiment is a plant state such as pressure and temperature from the plant 11 installed in each control device 71a, 71b,. Plant input means 72 for periodically taking in process data indicating the amount, alarm set value table 73 for storing alarm set values, alarm set value input means 74 for taking out alarm set values from the alarm set value table 73, input process data and An alarm determination unit 75 that determines whether or not an alarm is set from a corresponding alarm set value, an alarm determination information output unit 76 that outputs an alarm determination result and time as alarm determination information, and each control device 71a, 71b,. In the computer 78 connected via the alarm determination information input means 79 for inputting the alarm determination information from each of the control devices 71a, 71b,. A database 80 for storing names of input points to be performed, an alarm message generating means 81 for generating alarm message information based on the alarm determination information and the database 80, and a display processing means 82 for displaying the generated alarm message on the display device 1. Composed.

  Next, the operation of this embodiment will be described. In the control device 71b, the plant input means 72 periodically takes in plant state quantities such as pressure and temperature from the plant 11 as process data and notifies the alarm determination means 73. At this time, it is assumed that the process input value at the input point A0001 (main steam pressure) is 10 MPa and the process input value at the input point A0002 (main steam temperature) is 530 ° C.

  In the alarm set value table 73, the maintenance staff sets and changes the alarm set value for each input point from the set value changing device 83, so that the alarm set value and the upper / lower limit type are set for each input point. As value information, it is stored as shown in FIG.

  The alarm set value input means 74 extracts alarm set value information from the alarm set value table 73 for each input point of the input process data.

  The alarm determination means 75 is alarm set value information corresponding to the process input value from the alarm set value input means 74 and the main steam pressure = 10 MPa of the process input value taken in by the plant input means 72 and the main steam temperature = 530 ° C. An upper limit value of a certain main steam pressure = 15 MPa and an upper limit value of the main steam temperature = 500 ° C. are sequentially compared. The main steam pressure is normal because the process input value 10 MPa is smaller than the upper limit value 15 MPa of the alarm set value, and the next main steam temperature is an alarm because the process input value 530 ° C deviates from the upper limit value 500 ° C of the alarm set value. Set the alarm contact to be performed and the respective alarm time. In this case, the alarm contact at the input point A0001 = 0, the alarm contact at the input point A0002 = 1, and the alarm time at this time is 10: 15: 30.5 seconds at the input point A0001, and 10: 15: 31.0 seconds at the input point A0002. Suppose there was.

  The alarm determination information output means 76 has an alarm contact point = 0, 1, alarm time = 10: 15: 30.5 seconds, 10: 15: 31.0 seconds, and 10: 15: 31.0 seconds, which are the determination results of the alarm determination means 75, respectively. The process input value used for the determination = 10 MPa, 530 ° C. and the alarm limit value information = 15 MPa (upper limit value), 500 ° C. (upper limit value) are sent to the network 77.

  In another controller 71a, the process input values notified from the plant input means 72 to the alarm determination means 75 are reheat steam pressure (input point A0003) = 13 MPa, reheat steam temperature (input point A0004) = 480. Suppose that it was ℃.

  The alarm determination unit 75 inputs the process input from the alarm set value table 73 by the alarm set value input unit 74 with respect to the reheat steam pressure = 13 MPa and the reheat steam temperature = 480 ° C. of the process input values taken in by the plant input unit 72. The upper limit value of the reheat steam pressure = 10 MPa and the upper limit value of the reheat steam temperature = 450 ° C., which are alarm set value information corresponding to the values, are taken out and sequentially compared. The main steam pressure is an alarm because the process input value 13 MPa is larger than the upper limit value 10 MPa of the alarm set value, and the next reheat steam temperature is an alarm because the process input value 480 ° C deviates from the upper limit value 450 ° C of the alarm set value. Set the corresponding alarm contact and each alarm time. In this case, the alarm contact (input point A0003) = 1 and the alarm contact (input point A0004) = 1, and the alarm time at this time is 10: 15: 30.8 seconds (input point A0003), 10: 15: 31.5 seconds (input Point A0004).

  The alarm determination information output means 76 has an alarm contact point = 1, 1, alarm time = 10: 15: 30.8 sec, 10: 15: 31.5 sec, 10: 15: 31.5 sec, respectively, of the judgment results of the alert judgment means 75. The process input value used for the determination = 13 MPa, 480 ° C. and the alarm limit value information = 10 MPa (upper limit value), 450 ° C. (upper limit value) are sent to the network 77.

It is assumed that the correspondences between the alarm contacts, process input values, and alarm set value information are matched.

  In the computer 78, the alarm determination information input means 79 captures alarm contact, alarm time, process input value, and alarm set value information transmitted from the respective control devices 71a, 71b... Compare with the previous alarm contact that had been changed, and determine the order of early time according to the alarm time.

  Here, it is assumed that the previous alarm contact content is alarm contact (input point A0001), (input point A0002), (input point A0003), (input point A0004) = 1, 0, 0, 0.

  The judgment result is that the main steam pressure (input point A0001) at the alarm time 10: 15: 30.5 seconds is changed from the previous value 1 to the current value 0, so the alarm is restored. Second, the alarm time 10: 15: 30.8 seconds The reheat steam pressure (input point A0003) of the previous time is 0 → the current value 1, so an alarm is generated, and the third main steam temperature (input point A0002) at the alarm time 10: 15: 31.0 seconds is the previous value 0 → Since the current value is 1, an alarm is generated, and fourth, the reheat steam temperature (input point A0004) at the alarm time 10: 15: 31.5 seconds is changed from the previous value 0 to the current value 1, and an alarm is generated. Thus, the message creation request is notified to the warning message creation means 81.

  As shown in FIG. 15, the database 80 stores a correspondence table of input point numbers and process input value names.

  The warning message creating means 81 receives the warning message creation request from the warning judgment information input means 79, and the process input values of the input points A0001, A0002, A0003, A0004 = 10 MPa, 530 ° C., 13 MPa, 480 ° C. Information = 15 MPa, 500 ° C., 10 MPa, 450 ° C. is extracted from the alarm determination information input means 79, and the corresponding process input value name = main steam pressure, main steam temperature, reheat steam pressure, reheat steam temperature, 15 is taken out from the database 80 shown in FIG. 15 and alarm message display data is created and passed to the display processing means 82.

  FIG. 16 shows the warning message display data created by the warning message creation means 81.

The display processing means 82 takes out the alarm message display data notified from the alarm message creating means 81, displays it in red for an alarm occurrence message, and displays it in green to some extent that can be confirmed by the operator, and then deletes it. By designation, it is converted into display data of the display device 1 and display output to the display device 1 is performed.
Thereby, the display apparatus 1 displays an alarm message as shown in FIG.

  As described above, in this embodiment, the control device always reads the process input of the alarm target item, compares the predetermined alarm setting value with the process input, and when the process input value deviates from the alarm setting value, The alarm time and alarm contact indicating that the alarm has deviated, the current value of the process input at that time, and the alarm set value information used by the controller for comparison are sent to the computer. In addition, by outputting the alarm point name, the current value of the process input value, and the alarm set value as an alarm message to the display device, it is possible to eliminate the timing difference of alarm generation in two or more control devices.

  FIG. 18 shows a fifth embodiment of the present invention. The alarm device of this embodiment includes a plant input means 85 for inputting process data from the plant 11, an alarm set value table 86 for storing alarm set values, and FIG. The alarm setting value input means 87 for extracting the alarm setting value from the alarm setting value table 86, the process data from the plant input means 85, and the alarm setting value from the alarm setting value input means 87 are compared to determine the alarm state at each input point. Alarm determination means 88 for determining, alarm exclusion switch 89 for suppressing alarm output in advance, alarm window state memory 90 for storing the current display state of the alarm window, and input point information belonging to each alarm window are stored. Alarm window database 91 to be generated, alarm information generating means 92 for generating alarm information based on alarm determination information from alarm determination means 88, and generated alarm information It is constituted by a display processing unit 93 to be displayed on the display device 1.

  FIG. 19 shows a data configuration example of the alarm set value table 86, in which an alarm set value and its upper / lower limit type are stored for each input point of process data.

  FIG. 20 shows a data configuration example of the alarm window database 91, in which alarm window numbers, window names, and input point configuration information are stored in units of alarm windows divided for each plant system.

  Next, the operation of the present embodiment will be described. The plant input means 85 reads process values such as temperature, pressure, flow rate, and valve opening / closing from the plant 11 and notifies the alarm determination means 88 of the process values.

  The alarm determination unit 88 reads the alarm set value set in the alarm set value table 86 via the alarm set value input unit 87 with respect to the process value input point notified from the plant input unit 85, and the process value The alarm status at the input point is judged based on whether the alarm deviates from the alarm set value or falls within the alarm set value, and if it is an alarm, then the alarm is excluded for each alarm window or control device The state of the switch 89 is referred to. If this alarm exclusion switch 89 is in the exclusion state (ON), the result determined by the alarm determination means 88 is regarded as not an alarm. If the alarm exclusion switch 89 is in a non-exclusion state (OFF), the result determined by the alarm determination means 88 is regarded as an alarm. This determination result is notified to the alarm creating means 92.

  The alarm information creation unit 92 compares the alarm determination information at the input point notified from the alarm determination unit 88 with the previous value information, and determines whether or not the alarm state has changed.
