  FIG. 4 is a data configuration example of the business execution right schedule table 72. In the table shown in FIG. 4, the operation management of the devices in the area 1 is performed during the daytime on weekdays, the control center A is in charge of operation at night on Saturdays, Sundays, and nighttime on weekdays, during daytime on off days and holidays, and It is described that the control station B takes charge of the night on busy days, and that the control station A takes charge when the control station B or the control station C becomes unusable.

  Similarly, operation and management of equipment in area 2 is handled by control station B in the case of weekday daytime, weekday nighttime, off-day, holiday daytime, busy day night, and Saturday and Wednesday night. It is described that the control station A or C takes the place when B is not usable, and that the control station B takes charge when the control station A or C is unavailable. In this embodiment, there is no description of the date and time, but the operation location may be determined by specifying the date and time. Further, as shown in FIG. 19, the locations in charge may be registered in the order of priority, such as a primary station, a secondary station, and a tertiary station.

  This business execution right schedule table 72 is previously held by a control station, a sales office, and a power generation / substation that can be the operation location 2. In the case of area 1, management is performed by the control stations A and B, and the control stations A and B determine each other's operation status by referring to the monitoring packet. For example, by confirming the contents of the monitoring packet, the control station B, which is the secondary station, determines that the control station A, which is the primary station of the device 50 in a certain area, cannot operate due to a failure or system convenience. Can do.

  In that case, the control station B uses the monitoring packet for the relay station server 60 to change the control right route switch after obtaining the approval, change the execution right to itself, and change the contents of the control right route switch to the relay station server 60. By transmitting the data, the execution right of the control station A that has become unable to function can be deprived, and the control station B, which is the secondary station, can be set as the operation point in charge. It is mandatory to obtain the approval of the person in charge when changing the execution right, or the secondary station can change the execution right of the primary station even if there is no approval by the definition of a flag etc. It is also possible to select whether or not.

  Similarly, in the case of area 2, the control stations A, B, and C may be in charge as the operation point 2, so that the control stations A, B, and C each check a monitoring packet received from the relay station. However, in this figure, when the control station A is in operation, the control station C does not act on its behalf, so processing such as referring to it only when the control station B is in operation is performed. The same applies to area 3.

  In FIG. 19, since the primary station to the tertiary station are defined, the secondary station monitors when the primary station is operating, and the tertiary station monitors when the secondary station is operating. The operation such as performing is performed.

  FIG. 5 is a configuration example of the operation slip 71 describing the operation of each device. As shown in FIG. 5, items such as “command location”, “relay location”, “operation location”, “work content”, and “finished / unfinished” work can be described. The normal work is based on this operation slip 71. From the control location, which is the command location, the contact from the control location to the relay location is sent to the power center, and from the power location to the location where the operation location is located. A report is received by telephone, and based on the report, for example, “201 switchgear disconnection” described in the work content is executed. At the end of the operation, the “done / not yet” column is set to “done”.

  In the middle of a series of operations described in the operation slip 71, a failure or the like occurs in the operation location 2, and the relay station 6 detects it, sets that in the monitoring packet, and uses a virtual channel for each control station. To notify. Here, the virtual channel is assigned for switching the control right of a plurality of control stations, and switching control data or status between the control stations related to the transmission format (telecon format) of the remote monitoring control device. A channel for sending data.

  The control center or the like that has received the notification determines from the contents of the monitoring packet received on the virtual channel whether a failure has occurred at the current operation location 2 in the area where it may be in charge as the operation location 2. If a failure is detected and if the mobile station has the next priority as the secondary station, it is approved and the local area corresponding to the control right route switch shown in FIG. Is set to “ON”, and the column of the primary station in which the failure is detected is set to “OFF” to notify the relay station. The newly assigned secondary station can specify how far the work has been completed from the “done / not yet” column, and can instruct the in-area device 50 to perform the next operation.

  FIG. 6 is a configuration example of a monitoring packet indicating the state of a location such as a control station, a sales office, or a substation. In the present embodiment, OK / NG indicates whether each of the control station, the sales office, and the power substation is operating. For example, the information is notified from the relay server 60 by setting “0” for OK, “1” for NG, and the like. For example, in FIG. 4, the control station A is responsible for “weekday daytime” operation of the equipment in the area 1, but the control station B in charge of the next priority is the control station C1 in FIG. Yes, if C2 is the control station B, the information of C1 is always monitored, and when this information becomes NG (for example, 1), the failure of the control station A is detected, and the operation location server in charge of its own location Processing is performed as much as possible.

  FIG. 7 is a data configuration example of the control right root switch. The control right root switch is data indicating which part is the operation part 2 and the right to control the equipment in the area. The part having the control right for each area is turned on, and the other parts are off. It is in a state. This on / off state may be expressed as 0/1. FIG. 7 shows that the control right for area ID # 1 is in sales office A, the control right for area ID # 2 is in control office A, and the control right for area ID # 3 is in power station A. Yes. This data is used in real time because it is changed when the operation location 2 controls a device in the area from another location due to a failure or other reason. This control right route switch may represent the switches SW01 to SW04 shown in FIG.

  FIG. 8 is a data configuration example of the location state management DB 641 included in the relay station server 60. Packets when there is a change in status, for example, at regular intervals, or the operating status of command locations such as control stations, sales offices, and substations to be monitored, relay locations, and locations that may become operation locations Is acquired and registered in this DB. The monitoring packet described above is transmitted with reference to the present location state management DB 641.

  The power operation monitoring control system 1 in the first embodiment is configured as described above, and the operation thereof will be described below using a flowchart and the like.

[1. Control packet sequence]
FIG. 9 shows a sequence chart of control packet communication performed between the operation location, the relay station, and the device A in the area when the operation is performed. The control packet is a packet including a work command to be performed according to the operation slip 71. First, a control packet including work contents for the in-area device A is transmitted from the control station A, which is the primary station, to the in-area device A (A91), reaches the relay station, and is received by the relay station (A92). . This packet is, for example, the work content itself shown in the operation slip 71 of FIG. 5 or a selection control signal such as “selecting a circuit breaker 201” in which the work content is divided into more detailed procedures one by one.

  The relay station checks the error of the received control packet and checks the validity of the packet from the operation location server 20 having the control right (A92), and if there is no problem, controls the corresponding in-area device A. The packet is relayed (A93). The in-area device A performs, for example, “selects a blocker 201” according to the content of the received control packet. The intra-area device A transmits a response packet such as “201 blocker selection OK” to the relay server 60 as a response to the control packet including the received command (A94).

  The relay station that has received the response packet refers to the received business execution right schedule table 72 of the in-area device A, and forwards the response packet to a relevant location, for example, the control station A and the control station B in FIG. 9 (A95). , A96). Subsequent A97 to A9C include the next operation command, for example, a command such as “turn off the circuit breaker” that needs to be performed next, and the processing is performed in the same manner as A91 to A96. An operation command according to the operation slip 71 is executed in the above procedure.

[2. Monitoring packet sequence]
Next, the monitoring packet sequence will be described with reference to FIG. The monitoring packet is a packet for monitoring or notifying a state that can be a command point, a relay point, or an operation point, for example, a stop state, an adjustment state, or an operation state. In this embodiment, the information is received from the control station, the sales office, the substation, etc. to the relay station server 60, and the relay station server 60 manages the state.

  Although details of this monitoring packet are not described, it can be created according to the format of the control packet between the existing slave station and the control station, and a dedicated channel for monitoring is assigned to each control station, sales office, This is what the power substation has. Hereinafter, this channel is referred to as a virtual channel. For example, when there are 100 slave stations, the relay station server 60 has a channel for 100 slave stations and one virtual channel for monitoring a control station, sales office, and substation.

  For example, when the relay station server 60 transmits a monitoring packet using the virtual channel to the control station A and the sales office B which are the operation locations, for example, a flag indicating that the relay station server 60 is for the control station A and the sales office B is included in the packet. The control office A and the sales office B look at the flag, determine that the packet is for them, and perform operations such as capturing the monitoring packet. Similarly, it is possible to provide a pattern such as a predetermined flag for all locations.

  Alternatively, the monitoring packet can be transmitted and received after a link is established between the control office A and the sales office B using a virtual channel. FIG. 10 shows an example in which a monitoring packet is transmitted only to a predetermined place instead of establishing a link. However, in this example, all destinations are sent to the control station, sales office, and first substation, but the location designated as the destination acquires the data. Also, in FIG. 10, the monitoring location is composed of the command location, the relay location, the operation location # 1 and # 2, and the relay station, and receives a monitoring packet for notifying the state from the command location, the relay location, the operation location # 1 and # 2, In this example, the monitoring packet received by the relay station is sent to the command location, the relay location, and the operation locations # 1 and # 2 to monitor the status of each location.

  First, the command location, the relay location, and the operation location # 1 are their own states, for example, the states such as stop, adjustment, and operation are set in the monitoring packet and transmitted to the relay station (A101). This transmission trigger may be periodic communication, may be performed only when there is a change in state, or may be a response to polling from the relay station, although not described in the sequence chart. .

  The relay station extracts the state from the received monitoring packet, updates the location state management DB 641 shown in FIG. 8 storing the corresponding location state (A102), and transmits the received response packet. Communication procedures as indicated by A104 to A107 are similarly performed from the command location, the relay location, and the operation location # 2. Next, for example, the state updated periodically or triggered by the occurrence of some event is transmitted to the command location, the relay location, and the operation locations # 1 and # 2 in a monitoring packet that notifies the status. As a result, the command location, the relay location, and the operation locations # 1 and # 2 can know the state of each other.

  The command location, the relay location, and the operation locations # 1 and # 2 are, for example, all control stations, sales offices, power substations, and the like.

[3. Command control pattern]
FIG. 11 shows a command control pattern when the command route is the same and each control route switch is changed. In the figure, the command location is a sales office, and there is no change in the command location in this figure. The operation location 2 includes a sales office and a control office, a backup location, a power substation, and a machine side panel. As in this example, the switchboard or the machine side panel in the power substation becomes the operation location 2 and can be operated.

  Although not shown in the figure, between the operation location server 20 and the in-area device 50 always passes through the relay server 60 as shown in FIG. Therefore, in all of (1) to (8A) in FIG. 11, a relay station is interposed in the portion where C (operation command) is described, and the work content instruction from the operation location server 20 is always relay station. It is transmitted to the in-area device 50 via the server 60.

  Further, SW01 to SW04, which are the switch groups described in FIG. 11, are examples of control route switches. The state of SW01 to SW04 in FIG. 11 indicates the state of (1). In this case, the switch SW01 on the machine side panel of the substation and the switchboard SW02, the switch SW03 at the backup point, and the switch SW04 at the control station are It is off, and only the switch SW04 of the sales office is in the on state, indicating that the sales office performs control of the in-area device 50. The sales office also serves as a command location. In (2), the switch SW04 of the sales office and the control office is in the ON state, the sales office functions only as a command location, and the control office performs control of the equipment 50 in the area. .

The following describes (1) to (8A) when the control route is changed.
(1) The operation location is a sales office, and the in-area device 50 is directly operated by an operation command (A111) from the sales office. This operation is the same as that shown in FIG.
(2) The control station side of the switch SW04 of the sales office and the control office is turned on, and the operation location is the control office. Since the command location is a sales office, the business office contacts the control office by telephone (A112), and thereafter, the in-area device 50 is operated by an operation command from the control office (A113).
(3) The backup location SW03 is on, and the backup location is the operation location. A control command is sent from the sales office, which is the command location, to the backup location by telephone (A114), and the in-area device 50 is controlled by the command from the backup location (A115).

(4) This is a case where the substation is the operation location. In this case, the switch SW01 on the machine side panel of the power generation substation is in the off state, and the switch SW02 of the monitoring control device is in the on state, and the monitoring control device is operating as the operation location. Although only one in-area device 50 is shown in the figure, this means that the substation operates the own in-area device 50 or controls another in-area device 50. Also in this embodiment, the sales office that is the command location contacts the power generation / substation where the monitoring control device is installed by telephone (A116), and the monitoring control device issues an operation command to the target area device 50 (A117). ). Also in this case, the control is such that the operation command first reaches the supervisory control device or the machine side panel from the relay station after passing through the relay station.
(4A) The switch SW02 of the monitoring and control device of the power substation is in the OFF state, the switch SW01 of the machine side panel is in the ON state, and the machine side panel is in the operating position. The operation command is issued from the machine side panel (A118). Also in this case, the operation command is notified to the in-area device 50 through the relay station.

The above (1) to (4A) are examples that do not go through a relay location.
(5) This is an example in which a command is issued from the backup location via the relay location by telephone from the command location. First, the sales location that is the command location is contacted by telephone (A119), and the relay location is backed up by telephone. The location is contacted (A11A), and the backup location is operated by giving an operation command to the in-area device 50 (A11B). The book (4) is an example via the relay location in the above (3).
(6) This is an example of passing through a relay location in (4) above. The difference lies in the fact that there is a telephone contact from the sales office that is the command location to the relay location, and further there is a telephone contact from the relay location to the power substation where the monitoring and control device is installed.
(7) This is an example of using a backup location as the second relay location in (6) above.
(8) In this example (6), a backup location is used as a relay location.

[4. Registration of information]
FIG. 12 is a flowchart showing a processing procedure of an “information registration routine” for registering information in the operation location server 20 in the power system operation monitoring control system 1. This operation is performed by the information registration unit 233. Registration of information such as user information / destination information / threshold information, work equipment specifying file, etc. is performed directly using a keyboard or a screen connected to the input unit 25 and the display unit 26 of the operation location server 20.

  Connect using a personal computer as a terminal using a serial line (not shown), or connect to the network via an in-house LAN (Local Area Network) or communication network 4 and log in to make settings It is also possible to do. When setting information via a network, it is desirable to enhance security to encrypt ID and password transmission and data transmission / reception information. Hereinafter, a processing procedure in the case of performing registration using a keyboard directly connected to the operation location server 20 will be described with reference to FIG.

  First, a login request is made to the power system operation monitoring control system 1 (actually connected to the cable position information management server 2) by operating the keyboard (S121b). The operation location server 2 receives the login request (S121a), and requests an ID and password for logging in to the system (S122a). The request for the ID / password is displayed on the monitor screen or the like via the display unit 16 (S122b), the contents of the ID / password input by the operator are notified to the operation location server 20 (S123b), and the operation location server 2 receives information. Is received (S123a).

  The operation location server 2 acquires the user ID and password information in the user information DB 241 and determines whether they match the received ID / password (S124a). If the ID / password does not match, the process returns to step S122a and the above process is repeated again. When the ID / password matches, the operation location server 20 transmits a work selection screen or the like (S125a). Registration of various information can be selected on this screen.

  The received selection screen is displayed on the monitor screen of the operator (S124b), and it is notified that the registration work of information such as the business execution right schedule table and the operation slip 71 has been selected as the content selected by the operator (S125b). ). Upon receiving the request (S126a), the information registration unit 133 creates an input screen for information related to the business execution right schedule table and the operation slip 71, and displays the input screen on the screen handled by the operator through the display unit 16. (S127a).

  While viewing the screen (S126b), the operator inputs information related to the business execution right schedule table, operation slip 71, and the like using the keyboard. The input information is notified to the information registration means 233 via the input unit 15 (S127b). The information registration means 233 registers the information related to the entered business execution right schedule table and operation slip 71 in the business execution right schedule table 72 and operation slip DB 242 (S129a). Next, the information registration unit 133 creates a screen for selecting whether to continue or end the input and displays it on the screen (S12Aa).

  Looking at the displayed screen (S128b), the content selected by the operator is notified from the input unit 15 to the information registration means 233 (S129b, S12Ba). The received content is determined (S12Ca), and if the end is selected, this routine ends. When continuation is selected (no route of S12Ca), the process returns to step S122a and the above operation is repeated until the end of the process is selected.

  In the present embodiment, it is configured to determine whether to end or continue the input in step S12Aa. However, in the case of registration contents that must be continuously performed, the above S12Aa to S12Aa are used. The operation described in 12Ca is not performed, and the operation immediately returns to step S127a to continue to transmit a screen for inputting input information. In addition, when registration of input information is completed, other procedures such as transition to another screen may be performed.

[5. Creating operation slips for offline work]
FIG. 13 shows a flowchart when creating the operation slip 71 in the off-line work. In the present embodiment, the creation of the operation slip 71 in the off-line operation is first determined if the actual operation is performed, for example, one to two weeks ago, or not, the creation date of the operation slip being created (S131). If it is not the creation date, the process ends. In the case of the creation date, an operation slip that determines the command location, relay location, and operation location required for the operation slip 71 from the operation rules, the business execution right schedule table, and the control center state management table, and performs the power operation of the target device, etc. 71 is created (S132).

  Next, it is determined whether or not the creation of all operation slips 71 has been completed (S133). If not completed, the next target operation is designated (S134) and the process returns to step S132 to return all operation slips 71. The above process is repeated until the creation is completed. When the creation of all operation slips 71 is completed (yes route in S133), the created operation slip 71 is saved (S135) and created in a control station, sales office, substation, etc. that can be the operation location. (S136) and the process is terminated. A daily operation slip 71 is created by the above processing procedure and notified to necessary operation locations.

  Note that even when the operation is automated and the operation slip 71 is created earlier than 1 to 2 weeks, the date is changed from “2 weeks ago” to “1 day ago” in step S131 for checking the date. Just do it.

[6. Correction of operation slip in online business]
FIG. 14 shows a sequence chart and an operation flowchart when the operation location is forcibly changed when a failure occurs in the operation location 2 during operation or when it is desired to change the operation location manually. . The relay station server 60 and the operation location server 20 communicate with each other by, for example, periodically communicating or performing communication when something happens, for example, so that the relay station server 60 monitors the operation location server 20. Shall.

  In FIG. 14, it is assumed that the control station A is an operation point 2 as a primary station of the in-area device 50 (not shown), and the control station B is a secondary station of the same in-area device 50. The control station A notifies the control information as regular communication (S141a). When the relay station server 60 receives the regular communication (S141c), it checks the content (S142c). It is determined whether or not the failure information of the control center A exists in the received control information (S143c). If no failure is found, nothing is done (S147c) and the process is terminated.

  When a failure is detected in the control station A, a monitoring packet shown in FIG. 6 is created to indicate that the control station A has a failure in order to notify the detected failure information to the other operation location server 20 (S144c). ). Next, the contents are updated by registering that the control station A is in a fault state in the operation location state management DB 641 (S145c), and the created monitoring packet is transmitted to another control station, sales office, power generation / transformation using a virtual channel. (S146c).

  The transmitted monitoring packet is received at the control station A and the control station B, and other control stations, sales offices, substations, etc. (not shown) (S142a, S141b). The control station B refers to the received control packet and determines whether a failure has occurred in the primary station that is the secondary station (S142b). Even if the occurrence of a failure is detected, the process is terminated without doing anything unless it is a secondary station (no route in S142b).

  When it is detected that the primary station of the in-area device 50 that is the secondary station is a failure, first, the designated destination is notified of whether or not it can be handled as the operation location. And wait for an answer (S143b). An answer from the designated destination is determined (S144b), and if no OK answer is obtained (no route in S144b), the process ends without doing anything. In the case of OK (yes route in S144b), it is assumed that the user has agreed to deprive of the control right, and in the control right route switch packet, he / she becomes the execution right holder of the target in-area device 50 and a failure occurs. The control station is set to have no execution right (S145b), and a monitoring packet including the control right route switch is transmitted to the relay station server 60 (S146b).

  Next, the relay station server 60 that receives the monitoring packet including the control route switch (S148c) changes the operation location of the corresponding operation slip 71 to the control location B that is registered as a secondary station (S149c). ), A monitoring packet for notifying the relevant location that the operation slip 71 has been modified is created (S14Ac). The received monitoring packet including the control route switch and the monitoring packet created in step S14Ac are transmitted to the control stations A and B, other control stations, sales offices, and substations using the virtual channel (S14Bc). The above control stations A and B, other control stations, sales offices, power substations, etc. (S143a, S147b) have failed in the control station A due to the monitoring packet including the control route switch, and the devices in the target area It will be understood that 50 operation points have moved to the control station B.

  If a failure occurs at a control station or the like that is the operation location of the in-area device 50 by the above procedure, the relay station detects the occurrence of the failure and uses the virtual channel to send a control packet including failure information. If the part that is the secondary station can send the authorization by delegating the authority specified in advance, and if the answer may be delegated, use the control right root switch packet Since the authority is rewritten and the operation part described in the operation slip 71 being worked is corrected and the relevant part is notified, the work can be continued.

  FIG. 14 shows a case where a failure occurs in the operation location. However, if there is a change in the command location and the relay location, and the change contents can be identified by the monitoring packet, for example, the failure of the command location or the relay location. In the case of discovery or the like, it is possible to process in the same procedure as in FIG. Or, if the system administrator etc. wants to manually change the command location, relay location, operation location, etc., not only the “failure” detection by the monitoring packet shown in FIG. It is also possible to put control information indicating that the operation is desired, understand the contents at the operation location, and automatically correct the operation slip 71.

  Further, in the above example, the relay station server 60 corrects the operation slip 71 and notifies the relevant location, but if the operation location server 20 detects its own failure, the operation that has detected its own failure. It is also possible to correct the control route switch in the location server 20. Similarly, the operation slip 71 can be corrected by the operation location server 20 that has detected its own failure or the operation location server 20 that is the secondary station that has detected the failure of the primary station and notifies the relay station server 60 of it. is there.

[7. Processing during operation slip execution]
FIG. 15 is a flowchart illustrating a processing procedure of an operation in which the operation location server 20 processes a work based on the operation slip 71. This operation is an operation performed by the operation form execution unit 533, and the processing will be described below with reference to FIG.

  First, it is checked by referring to the control route switch whether or not it is controlling the corresponding area (S151). The contents of the control route switch are notified from the relay station periodically or when there is a change. If it is not the operation location where the user has the right to control the area, the operation of reading the operation slip 71 is stopped and the process is terminated (S159). If there is a failure due to this processing, or if the operation location is changed for some reason, the current processing can be stopped. If the current operation location can detect a failure by itself, the operation can be stopped by itself.

  If the operation location has not been changed, the procedure registered in the operation slip 71 is executed (S152). It is determined whether there is no problem in the execution result (S153). If there is no problem, “execution OK” is output to the buffer (S154). If there is a problem, “execution NG” is output to the buffer (S155). The contents of the buffer are output as a result (S156). The output result is transmitted to the relay station server 60. If this output result is OK, “completed” is written in the work described in the corresponding operation slip 71. If the output result is NG, it can be dealt with separately.

Next, it is determined whether or not all the operations registered in the operation slip 71 have been completed (S157). If not completed, the next operation is designated, and the process returns to step S151 to repeat the above processing. If completed (yes route in S153), the process ends. The work registered in the operation slip 71 by the above processing is performed one by one in order, the result is notified to the relay station, and the relay station server 60 transfers the result to the relevant location, thereby allowing the secondary station It is possible to know the operation performed by the primary station and its result.
The first embodiment of the present invention is configured and operates as described above.

  According to the present invention, the relay station 6 is provided between the operation location server 20 that actually gives a work instruction to the power system device and the in-area device 50, and the relay station server 60 provides a command location, a relay location, and an operation location. Based on the business execution right schedule 72 that gives control priority to the operation location server 20 that monitors possible control stations, sales offices, substations, etc. and controls the in-area devices 50, the in-area devices 50 By managing the control right to control the operation route with the control route switch, the failure of the operation location server 20 or the change of the operation location 2 for some reason can be flexibly responded to the request of the equipment of the power system. Operation management can be performed.

  Next, a second embodiment will be described below. FIG. 16 shows a functional block diagram of the relay station server 2 according to the second embodiment of the present invention. Compared to the first embodiment, there is a failure notification unit 637 for notifying a predetermined destination when a failure is detected in the central processing unit 63, and the failure is detected in the storage unit 64. However, there is a notification destination database (DB) 642 for storing a destination to be notified at the time.

  FIG. 17 is a data configuration example of the notification destination DB 642 that stores a destination to be notified when a monitoring result notification or a failure is detected. As a notification destination, a notification destination name, a notification method such as telephone / FAX / email / Internet use, and a notification destination such as a notification destination telephone number / FAX number / email are stored for each notification destination.

  The power system operation monitoring control system 1 in the second embodiment is configured as described above, and only the operation different from that of the second embodiment will be described below using a flowchart and the like.

[8. Failure detection notification]
FIG. 18 is a flowchart showing the processing procedure of the “failure notification routine” that operates when a failure is detected at a location in the power system operation monitoring control system 1, and this operation is performed by the failure notification means 637. . Hereinafter, the processing will be described with reference to FIG. First, referring to the notification destination DB 642 shown in FIG. 17, the notification destination, the notification method, and the notification destination are acquired (S181), and the process branches according to the notification method (S182).

  When notifying by e-mail, an e-mail notifying the failure occurrence status is created and set in the body of the e-mail, and the destination of the acquired e-mail is set as the destination. (S183). Next, the created mail is transmitted (S184), and the process proceeds to step S18C. When notifying by FAX, the failure occurrence status is electronically created and output as a file (S185), notified by calling the destination and transmitting by FAX protocol (S186), and proceeds to step S18C.

  In the case of notification by telephone, a voice file is generated to notify the failure occurrence status (S187), the acquired destination is called, the voice file is played back when the other party answers (S188), and the process proceeds to step S18C.

  In the case of using the Internet, first, a file notifying the failure occurrence state is created (S189), the created file is placed in a specific place where it can be referred to by a specific protocol (S18A), and a specific means that the file is placed in a specific place. For example, notification is made by e-mail (S18B). When the specific protocol is HTTP (HyperText Transfer Protocol) notification, a file is placed in a location accessible by HTTP, such as a server that can be referred to from the outside, and a URL (Uniform Resource Locator) indicating the location is sent using e-mail Notice.

Next, in step 18C, it is determined whether or not the processing for all destinations has been completed. If not, the next destination is designated (S18D), and the process returns to step S181 to process all registered destinations. The above operation is repeated until the end. If all destinations have been processed (yes route of S18C), the process of this routine is ended. In such a procedure, the failure occurrence status can be notified to a predetermined destination. In this embodiment, the result of the operation status is described in the body of the mail. However, a file representing the operation status is created, and for example, encryption is performed to ensure the safety, and then transmitted and received. The method of decoding and receiving on the side may also be used.
The second embodiment of the present invention is configured and operates as described above.

  According to the present embodiment, when a failure occurrence is detected, it is possible to automatically notify a destination registered in advance, so that it is possible to quickly cope with the failure.
