  By the way, in the conventional rack-type monitoring simulator described above, a large number of switches and lamps are arranged on the front panel, and a display unit (display sticker A display plate) is pasted in the vicinity of these switches and lamps.

  As described above, since the front panel of the monitoring simulation apparatus is provided with a large number of switches, lamps, and display units, it is difficult to see the switches, lamps, and display units at positions away from the front panel. There is a high possibility of misselecting the switch to be switched, whether or not the lamp is lit, and the display section being misinterpreted, the operability of the monitoring simulator is poor, and it takes time for the operation check test of sequence control of the switchboard It was the current situation.

  In addition, it is necessary to check the operation check items of the switch and display unit provided on the front panel of the monitoring simulator and the system diagram, and from this verification, it is determined which system component of the system diagram is the operation check. Therefore, the collation work is complicated, and this also requires time for the operation confirmation test.

  Furthermore, since the manufacturer that manufactures the switchboard conducts an operation check test in the presence of the customer who uses the switchboard, even if a large number of customers try to view the front panel of the monitoring simulator, At a remote location, it is difficult to select the switch, whether the lamp is lit, and the operation check items on the display section, and it is difficult for customers to understand the operation check test.

  Therefore, the present invention has been proposed in view of the above-mentioned problems, and the object of the present invention is to allow a quick and easy implementation of a sequence control operation check test of the switchboard, and the contents of the operation check test. It is another object of the present invention to provide a monitoring simulation device that can be easily understood.

On the other hand, if the control drawing captured in the personal computer is displayed as the wallpaper on the monitor screen as described above, the display of the control drawing on the monitor screen can be simplified, and the control drawing can be changed quickly. It becomes possible to respond.

  In addition, an icon that can be moved on the monitor screen is associated with a system component and placed at a predetermined position in the control drawing, so that the icon can be used as a symbol of the system component. By making the light emission state of the icon changeable according to the situation, the situation of a specific system component can be easily grasped.

  Note that when the present invention is applied to an automatic monitoring system for a power system, the control unit of the automatic monitoring system includes, for example, a distribution board of power distribution equipment installed in a substation or the like. A personal computer is connected to the switchboard in the automatic monitoring system of the power system through an interface, and the control drawing of the automatic monitoring system is displayed on the monitor attached to the personal computer by the above-described method.

  In this case, there is a system diagram of system components consisting of circuit breakers and disconnectors as one control drawing, and simulation of on / off of the circuit breakers and disconnectors is performed based on the operation of icons arranged for each circuit breaker and disconnector. Therefore, it is desirable that the on / off state of the circuit breaker and the disconnecting device can be displayed by changing the emission color of the icon corresponding to the circuit breaker and the disconnecting device. In this way, the on / off state of the circuit breaker and disconnector can be easily grasped by changing the emission color of the icon.

The monitor 4 can display the status of system components in the control drawing of the automatic monitoring system in a simulated manner. In addition, as the above-mentioned sequencer 2, the general thing comprised from a power supply unit, CPU unit, an output unit, and an input unit can be used. As the monitor 4, it is effective to use a large liquid crystal display when the manufacturer of the switchboard 1 performs an operation confirmation test in the presence of a large number of customers who use the switchboard 1. It is.

  FIG. 2 illustrates a state in which one control drawing in the automatic monitoring system is displayed on the monitor screen 4a. This control drawing is a system diagram 5 including a plurality of circuit breakers 6 and a disconnecting switch 7 as system components that the distribution board 1 performs sequence control. FIG. 3 illustrates a state in which another control drawing in the automatic monitoring system is displayed on the monitor screen 4b. This control drawing is a list 8 composed of failure items 9 of system components that are controlled by the switchboard 1 in sequence. The system diagram 5 or the list diagram 8 is taken into the personal computer 3 as a bitmap file or a PDF file by a scanner or the like prior to the operation confirmation test, and is displayed as wallpaper on the monitor screens 4a and 4b.

  In this way, the system diagram 5 or list diagram 8 of the automatic monitoring system is taken into the personal computer 3 by a scanner or the like, and the fetched system diagram 5 or list diagram 8 is displayed as the wallpaper of the monitor screens 4a and 4b. Therefore, the system diagram 5 or the list diagram 8 can be easily displayed on the monitor screens 4a and 4b in a short time.

  That is, when the system diagram 5 or the list diagram 8 is to be displayed on the monitor screens 4a and 4b of the personal computer 3 by programming, it takes a lot of time and labor to create the system diagram 5 or the list diagram 8 by the programming. It will be.

  On the other hand, if the system diagram 5 or the list diagram 8 taken into the personal computer 3 as described above is displayed as the wallpaper of the monitor screens 4a and 4b, the monitor screens 4a and 4b in the system diagram 5 or the list diagram 8 are displayed. In addition, even if there is a change in the system diagram 5 or the list diagram 8, it is only necessary to capture it by a scanner or the like, so that it is possible to quickly cope with a change in the specification.

  On the other hand, by using dedicated software, the icons 11 to 13 that can be moved on the monitor screens 4a and 4b are associated with the system components and arranged at predetermined positions in the system diagram 5 or the list diagram 8, and the system components The light emission form of the icons 11 to 13 can be changed according to the situation. As described above, the icons 11 to 13 that can be moved on the monitor screens 4a and 4b are associated with the system components and arranged at predetermined positions in the system diagram 5 or the list diagram 8, so that the icons 11 to 13 are configured in the system configuration. It can be used as an element symbol or the like, and by making the light emission state of the icons 11 to 13 changeable according to the status of the system component, the status of a specific system component can be easily grasped. .

  When the icons 11 to 13 are used as symbols or the like of the system components, the icons 11 to 13 are clicked to change the shapes and sizes of the icons 11 to 13 to the shapes and sizes of the symbols or the like of the system components. It is possible to adjust arbitrarily according to.

  In the system diagram 5 shown in FIG. 2, an icon 11 (square cross-hatched portion in the figure) that can be moved on the monitor screen 4a is associated with the circuit breaker 6 by numbering or the like and an icon 12 (round cross-hatched portion in the figure). ) Is associated with the disconnector 7 by numbering or the like, and the respective circuit breakers 6 and the icons 11 and 12 associated with the disconnector 7 are moved to the positions of the corresponding circuit breakers 6 and disconnectors 7, respectively. The on / off state of the circuit breaker 6 and the disconnecting switch 7 is displayed by changing the emission color of the icons 11 and 12 corresponding to the circuit breaker 6 and the disconnecting circuit 7.

  For example, if the circuit breaker 6 and the disconnecting switch 7 are in the off state, the emission color of the icons 11 and 12 is green, and if the circuit breaker 6 and the disconnecting switch 7 are in the on state, the emission color of the icons 11 and 12 is. Is red. In this way, the on / off state of the breaker 6 and the disconnector 7 can be easily grasped by changing the emission color of the icons 11 and 12.

  During the operation check test by the monitoring simulator, the circuit breaker 6 and the disconnector 7 are turned on and off based on the operation of the icons 11 and 12 arranged for each of the circuit breaker 6 and the disconnector 7. That is, when the icons 11 and 12 are clicked, a pop-up screen is displayed, and on / off of the breaker 6 and the disconnector 7 is selected on the pop-up screen.

  First, when the circuit breaker 6 and the disconnecting switch 7 are turned off, an off command signal for the circuit breaker 6 and the disconnecting switch 7 is transmitted from the personal computer 3 to the switchboard 1 via the sequencer 2, and the switchboard 1 corresponding to the switchboard 1 corresponds. If the disconnector 7 is controlled to be turned off, the off control signal is returned to the personal computer 3 via the sequencer 2, and the emission colors of the corresponding circuit breakers 6 and the icons 11 and 12 of the disconnector 7 are displayed in green.

  Further, when the circuit breaker 6 and the disconnecting switch 7 are turned on, an on command signal for the circuit breaker 6 and the disconnecting switch 7 is transmitted from the personal computer 3 to the switchboard 1 via the sequencer 3, and the switchboard 1 corresponding to the switchboard 1 corresponds. If the disconnector 7 is on-controlled, the on-control signal is sent back to the personal computer 3 via the sequencer 2, and the corresponding light emission color of the icons 11 and 12 of the breaker 6 and the disconnector 7 is displayed in red.

  In this system diagram 5, in addition to iconifying the circuit breaker 6 and the disconnecting switch 7, status items 14 and 15 such as “voltage present” and “far” are also iconified, and character icons 16 and 17 (in the drawing) The light emission color of the square cross-hatched part is green. As for the iconified status items 14 and 15, a pop-up screen can be displayed by clicking the character icons 16 and 17, and the status items 14 and 15 can be rewritten on the pop-up screen.

  As described above, in FIG. 5, the case where the circuit breaker 6 and the disconnecting switch 7 are iconized has been described. However, the wiring 18 that connects the circuit breaker 6 and the disconnecting switch 7 can also be iconized. In this case, the shape of the icon is adjusted so as to be elongated according to the shape of the wiring 18, and the icon is moved to the wiring at a predetermined position to be matched. If it does in this way, in addition to the on-off state of the circuit breaker 6 and the disconnector 7, it will become possible to display clearly the conduction | electrical_connection and non-conduction location of the wiring 18. FIG.

  In the list 8 shown in FIG. 3, the icons 13 (square cross-hatched portions in the figure) that can be moved on the monitor screen 4b are associated with various failure items 9 by numbering or the like, and are associated with various failure items 9. The icon 13 is moved to the position of the corresponding failure item 9 (upper right position of each column) and arranged. The status of the failure item 9 is displayed by changing the emission color and the emission state of the icon 13 corresponding to the failure item 9.

  For example, if the failure item 9 is normal, the emission color of the icon 13 is black, and if the failure item 9 is abnormal, the emission color of the icon 13 is red and flickers. In this way, the status of the failure item 9 in the automatic monitoring system can be easily grasped by changing the emission color and the emission state of the icon 13. The reason why the light emission color of the icon 13 is black and the light emission color of the icons 11 and 12 is different from green is to distinguish between the system failure display by the icon 13 and the on / off display by the icons 11 and 12. It is.

  When the status of the failure item 9 described above is displayed with the emission color and emission state of the icon 13, the failure item 9 is transmitted by transmitting a normal signal or an abnormality signal output from the switchboard 1 to the personal computer 3 via the sequencer 2. If 9 is normal, the emission color of the icon 13 is black, and if the failure item 9 is abnormal, the emission color of the icon 13 is red and flickers. The display switching of the icon 13 can be performed only by the presence / absence of an abnormal signal output from the switchboard 1.

  As described above, when the monitoring simulator is used for the operation check test of the sequence control of the switchboard 1 in the automatic monitoring system of the power system, the preparation work of the operation check test can be shortened as much as possible, and the operation check test can be performed quickly. It can be easily implemented, and the contents of the operation confirmation test can be easily understood. That is, the operability of the monitoring simulation apparatus is improved as compared with a conventional rack-type monitoring simulation apparatus, and the time required for the sequence control operation confirmation test of the switchboard 1 can be shortened. Further, it is not necessary to collate the operation check item with the system diagram, and the efficiency of the test work can be improved. Furthermore, even when the operation confirmation test is performed in the presence of a large number of customers, the contents of the operation confirmation test can be easily understood by the customer, and the customer satisfaction can be improved.

  In the above-described embodiment, the case where the operation check test of the switchboard in the automatic monitoring system of the power system is applied has been described, but the operation check test of the control unit in the automatic monitoring system of the water treatment system such as sewage treatment is also applied. Is possible.
