Japanese Patent No. 4072290 JP 2006-270662 A

  However, when multiple events occur at almost the same time in multiple facilities, such as a wide-area power outage accident, reporting individual event information to the report destination each time is extremely useful for reporting all event information. It took a long time, and there was a problem that the facility manager who received the report hindered quick response.

  For example, in an event notification system with ten facilities and five notification destinations, assuming that the event notification time per facility takes three minutes, all events are reported to all notification destinations. It takes 150 minutes to complete.

  There is also a problem that the administrator of the report destination needs to listen to the individual event information by voice reported from the report apparatus over a long period of time and respond according to the content, which is very complicated.

  On the other hand, the communication master station detects that a similar event is occurring in multiple facilities, and collects event information that indicates that an event is occurring in multiple facilities without specifying the facility or event to each report destination. Although it is conceivable to report, it takes time even if the communication master station collects all information from the communication slave stations installed in each facility to determine the event occurrence status, and the report is delayed. There was also a problem.

  In view of the above-described problems, an object of the present invention is to provide an event notification system capable of promptly reporting to all report destinations even when a plurality of events occur at substantially the same time.

  In order to achieve the above-mentioned object, the first characteristic configuration of the communication system according to the present invention is as described in claim 1 of each of the claims. A communication device having a function of monitoring the operating state of the equipment is provided, and in one communication device set as the communication master station, the failure occurrence acquired from the local station equipment or another communication device set as the communication slave station or A reporting device for reporting event information related to failure recovery via a public line, wherein the communication master station stores facility identification information for identifying an event generating facility and event type information for identifying an event type when the event information is acquired; In addition, the individual event information including the equipment identification information and the event type information is automatically notified to a preset notification destination via the notification device. In the event notification system configured, the communication master station operates a predetermined delay timer at the time of acquisition of event information, and the event information stored in the storage unit when the delay timer counts up The event information is automatically notified to the report destination when the number of events is less than a predetermined number, and the batch event information indicating that a plurality of events are occurring instead of the individual event information when the number is equal to or greater than the predetermined number The point is that it is configured to automatically notify the report destination.

  When the communication master station acquires event information from its own equipment or communication slave station, the communication master station activates a predetermined delay timer without immediately automatically reporting it, and other information acquired until the delay timer counts up. Event information is stored in the storage unit. When the delay timer counts up, the communication master station counts the number of event information stored in the storage unit, and determines that it is not an event in which many failures occur simultaneously when the number is smaller than the predetermined number. To automatically notify individual event information to the reporting destination. In addition, when the number of event information stored in the storage unit is greater than or equal to the predetermined number, it is determined that a large number of failures occur at the same time, and multiple events are occurring instead of individual event information. The collective event information is automatically reported to the report destination.

  Therefore, when the number of event information is less than the predetermined number, accurate event information can be quickly reported to the report destination, and when the number of event information is more than the predetermined number, there are multiple events at the report destination. You will be able to report quickly.

  In the second feature configuration, in addition to the first feature configuration described above, the communication master station activates a limit timer longer than the delay timer when acquiring the first event information. In addition, the delay timer is updated every time an event is acquired, and when the limit timer counts up before the delay timer counts up, the batch event information is automatically reported to the report destination.

  When the delay timer is short, the number of pieces of acquired event information does not reach the predetermined number, and eventually the individual notification is unavoidable, and the individual notification is repeated, so that the notification time becomes long. If the delay timer is long, the probability that the number of acquired event information will be greater than or equal to the predetermined number will increase, and the chance of batch notification will increase, but if it is an event that occurs sporadically rather than an event that occurred all at once There is a problem that the report is delayed. Therefore, if the delay timer is configured to update every time an event is acquired, if the event occurs sporadically, the probability that the delay timer is updated is low and the delay timer counts up early. In addition, you will be able to report quickly. On the other hand, if the events occur at the same time, there is a high probability that the delay timer will be updated and the notification may be delayed, but the limit timer counts up longer than the delay timer that was activated when the first event information was acquired. As a result, the collective event information is automatically notified to the report destination.

  In the third feature configuration, as described in claim 3, in addition to the first or second feature configuration described above, the communication master station, when the acquired event information is specific event information, When the event information is acquired, the delay timer is activated, and when the delay timer is not activated, the individual event information is automatically notified to the report destination.

  Since there is a low probability that various failures will occur in multiple facilities at the same time, and failures that occur simultaneously in multiple facilities are limited, it seems to occur sporadically when the delay timer is operated uniformly. Will delay the reporting of important events. Therefore, by operating the delay timer only for failures that occur at the same time in multiple facilities, it is possible to report as batch event information, but events that occur sporadically can be quickly identified as individual event information. It becomes possible to automatically report to the report destination.

  As described in claim 4, the fourth characteristic configuration includes a communication device having a function of monitoring the operating state of each facility in each of a plurality of facilities scattered in a predetermined area, One communication device set as, comprising a reporting device for reporting event information about occurrence of failure or failure recovery acquired from other communication devices set as the local station equipment or communication slave station via a public line, The communication master station stores, in the storage unit, the equipment identification information for specifying the event generating equipment and the event type information for specifying the event type at the time of acquisition of the event information. An event reporting system configured to automatically report individual event information including the equipment identification information and event type information, wherein the communication master station When the individual event information is automatically notified to the notification destination at the time of acquisition, and the number of unreported event information stored in the storage unit is less than a predetermined number when the notification to each notification destination is completed The individual event information is automatically notified to the notification destination, and when the number of events exceeds a predetermined number, the event information is automatically notified to the notification destination that a plurality of events are occurring instead of the individual event information. There is in point.

  According to the above configuration, the event information acquired to the communication master station is immediately and automatically notified as individual event information immediately, and the event information acquired to the communication master station during the automatic notification is stored in the storage unit. At the end of the automatic notification, the communication master station counts the number of event information stored in the storage unit, and if it is less than the predetermined number, it determines that it is not an event in which many failures occur at the same time. Automatically report event information to the report destination. In addition, when the number of event information stored in the storage unit is greater than or equal to the predetermined number, it is determined that a large number of failures occur at the same time, and multiple events are occurring instead of individual event information. The collective event information is automatically reported to the report destination.

  In the fifth feature configuration, as described in claim 5, in addition to any of the first to fourth feature configurations described above, the communication master station sends each batch event information to each report destination. When the notification ends, the individual event information is automatically notified to the notification destination when the number of unreported events stored in the storage unit after the start of reporting of the collective event information is less than the predetermined number, When the number is greater than or equal to the number of events, the event information is configured to automatically notify the notification destination of batch event information indicating that a plurality of events are occurring instead of the individual event information.

  In many cases, a plurality of managers are set as report destinations, and it takes, for example, several minutes to several tens of minutes before reporting of collective event information to all managers is completed. When new event information is accumulated by the end of the collective event information report to all administrators, the same process, that is, the individual event information report process and the collective event information report process are accumulated, After reporting the collective event information to all managers, reporting of unreported event information is repeated, resulting in poor efficiency.

  Therefore, when the number of unreported events accumulated in the storage unit during reporting of batch event information is less than a predetermined number, individual event information is automatically notified to the notification destination, and when the number of events exceeds the predetermined number, Alternatively, unreported event information can be reported efficiently by automatically notifying the report destination of batch event information indicating that a plurality of events are occurring.

  The sixth feature configuration is the event information stored in the storage unit in addition to any of the first to fifth feature configurations described above, as described in claim 6. When the number of cases is equal to or greater than the predetermined number and extends to a plurality of facilities, the collective event information includes information indicating that an event is occurring at the plurality of facilities and is configured to automatically notify the notification destination. There is in point.

  According to the above-mentioned configuration, when more than a predetermined number of events reach multiple facilities, the event information is automatically recorded in the collective event information, for example, “Multiple facilities have failed”. By automatically reporting to the reporting destination, including the fact that a problem has occurred, the administrator can recognize that a failure has occurred over a wide range and can respond quickly.

  In the seventh feature configuration, as described in claim 7, in addition to any of the first to sixth feature configurations described above, the communication master station is configured to automatically report the batch event information, or When a request for inquiry of individual event information is received from a report destination or a reference destination via the notification device after automatic notification, the individual event information stored in the storage unit at that time is notified of the request for the reference. The point is that an automatic notification is made to the destination or the inquiry destination via the notification device.

  The collective event information is information for promptly reporting to the report destination that a plurality of events are occurring. For this reason, since the equipment identification information and event type information reported by the individual event information are unknown, it is impossible to grasp what kind of event has occurred in which equipment, and it is impossible to take appropriate measures. However, when a request for inquiry of individual event information is received from the report destination or reference destination via the notification device at the time of automatic notification of batch event information or after automatic notification, it is stored in the storage unit at that time by the communication master station The individual event information that has been sent is automatically reported to the reporting destination or the querying destination where the query is requested via the reporting device. As a result, the latest individual event information can be confirmed at the report destination or the inquiry destination.

  In the eighth feature configuration, as described in claim 8, in addition to any of the first to seventh feature configurations described above, the communication master station receives collective event information including an event related to failure recovery. In the case of automatic notification, there is a point to automatically report by adding individual event information related to an event of a different type from an event related to failure recovery of equipment recovered from a failure.

  When the number of events stored in the storage unit is equal to or greater than the predetermined number, the communication master station reports batch event information. If the batch event information includes an event related to failure recovery, the storage unit stores that the failure has been recovered. There may be other failures caused by the failure in the installed equipment. Even in such a case, since the individual event information related to the event that is different from the event related to the failure recovery of the equipment recovered from the failure is added and automatically notified, the administrator who is notified of the individual event information You will be able to take appropriate action quickly.

  In the ninth feature configuration, as described in claim 9, in addition to any of the first to eighth feature configurations described above, the communication master station includes the same type of events. When the event information is automatically notified, the event confirmation information that the events that have occurred in a plurality of facilities have been confirmed is automatically notified after a predetermined time has elapsed since the acquisition of the latest event information.

  The communication master station automatically reports collective event information consisting of the same type of event, and when a predetermined time has elapsed since the acquisition of the latest event information, all event information that occurred all at the same time is acquired. It is determined that the event that has occurred in the facility has been confirmed, that is, all events have been acquired, and event confirmation information is automatically reported. As a result, it is possible to confirm that a new event does not occur in the report destination to which the event confirmation information is automatically reported.

  In the tenth feature configuration described in claim 10, in addition to any of the first to ninth feature configurations described above, the communication master station automatically reports the collective event information. In addition, the name of the event generating equipment is added to automatically report.

  According to the above configuration, the event occurrence facility name is added to the collective event information and an automatic notification is made, so the administrator who is notified can grasp the facility where the event has occurred and take appropriate measures. Can be taken.

  In the eleventh feature configuration, as described in claim 11, in addition to the ninth feature configuration described above, when the communication master station automatically reports the event confirmation information, the name of the event generation facility is set. In addition, it is in the point of automatic notification.

  According to the above configuration, since the event occurrence equipment name is added to the event confirmation information and automatically notified, the notified administrator can grasp which equipment the event has been confirmed, and take appropriate measures. Can be taken.

  As described above, according to the present invention, it is possible to provide an event notification system capable of promptly reporting to all report destinations even when a plurality of events occur at substantially the same time.

  Among the communication devices 30 (30-1 to 30-n), one communication device 30 (30-1) is set as a communication master station, and the other communication devices 30 (30-2 to 30-n) communicate. The slave station is set. A communication network is constructed in which the communication master station 30 (30-1) acquires the above-described operation information and event information from each of the communication slave stations 30 (30-2 to 30-n).

  In this embodiment, a small area wireless communication network using a new simple wireless method is adopted as a communication network, but a wireless communication network based on another standard using a different frequency band can also be adopted, and a private leased line. It is also possible to adopt a wired communication network that employs.

  As shown in FIG. 3A, each communication device 30 includes a communication control unit 31 incorporating a microcomputer, a route information storage unit 32, a modulation / demodulation unit 33, a transmission / reception unit 34 having an antenna, A facility information storage unit 35 that stores operation information and event information acquired from the control unit 22 is provided. The route information storage unit 32 and the facility information storage unit 35 are configured by SRAM, and further provided with a non-volatile semiconductor memory for backup.

  The operation information and event information output from the control unit 22 to the communication device 30 are stored in the facility information storage unit 35 via the communication control unit 31.

  The communication control unit 31 receives a monitor signal indicating whether a proper output voltage is output from the DC power supply device or whether a power failure has occurred. When the communication control unit 31 detects a power failure based on the monitor signal, the communication control unit 31 stores event information indicating the occurrence of the power failure in the facility information storage unit 35. Store information.

  The communication control unit 31 is driven by a backup power source when a power failure occurs, and when the capacity of the backup power source falls below a predetermined capacity, the data stored in the route information storage unit 32 and the facility information storage unit 35 is saved in the nonvolatile semiconductor memory. Control to do.

  The communication master station 30 (30-1) includes other equipment 10 (10-2 to 10-n) acquired from the local station equipment 10 (10-1) or the communication slave station 30 (30-2 to 30-n). ) Is connected to a notification device 40 for reporting the operation information and event information to the outside via a public line. In the present embodiment, an automatic telephone reporting machine is used as the reporting device 40.

  The communication control unit 31 stores the operation information and event information acquired from the control unit 22 in the facility information storage unit 35, reads out the operation information or event information stored in the facility information storage unit 35 at a predetermined time, and performs the operation Communication data (hereinafter also referred to as “frame data”) in which the wireless transmission route information stored in the route information storage unit 32 is added to the information or event information is generated and output to the modulation / demodulation unit 33.

  The modulation / demodulation unit 33 modulates a carrier having a predetermined frequency based on the frame data, transmits the carrier to another communication device 30 via the transmission / reception unit 34, and receives from the other communication device 30 via the transmission / reception unit 34. The frame data demodulated from the carrier is output to the communication control unit 31.

  As shown in FIG. 3B, the frame data includes a start identification data area indicating the start of data, a receiving station address, a transmitting station address, an address area for setting a plurality of relay station addresses, operation information and event information. And an end identification data area indicating the end of data.

  The operation information and event information are allocated to the information area (the frames described as information 1 and information 2 in FIG. 3B and the number of information frames is not limited), and the route information storage unit 32. Is set with a receiving station address, a transmitting station address, and a plurality of relay station addresses.

  The frame data is transmitted from the communication device 30 having the transmission station address to the communication device 30 having the reception station address via the communication device 30 of each relay station.

  More specifically, after handshaking based on a predetermined communication protocol between the communication control unit 31 of the source station address and the communication control unit 31 of the relay station 1, the frame data is transmitted, and then the communication of the relay station 1 The procedure that the frame data is transmitted after handshaking based on a predetermined communication protocol between the control unit 31 and the communication control unit 31 of the relay station 2 is repeated based on the route information set in the frame data. Finally, it is transmitted to the communication control unit 31 of the receiving station address.

  When the transmission of the frame data is completed between the pair of communication control units 31, the acknowledge signal is transmitted to the upstream communication control unit 31 in the reverse order of the route information set in the frame data, and the communication control unit for the source station address In FIG. 31, it can be confirmed whether or not the transmitted frame data is finally received by the communication control unit 31 of the receiving station address.

  Each route information storage unit 32 stores a plurality of route information with priorities. The communication control unit 31 of the transmitting station address determines that the transmission has not been properly completed when the acknowledge signal from the communication control unit 31 of the receiving station address for the transmitted frame data is not received, and determines the next priority order. Frame data is generated based on the route information and the same processing is repeated.

  Accordingly, the communication control unit 31 for the originating station address can confirm the address of the relay station or receiving station from which the frame data has been properly received based on the acknowledge signal, and identifies the communication control unit 31 that has failed. It is configured to be able to.

  Hereinafter, the operation of communication control by the communication control unit 31 provided in each communication device 30 (30-1 to 30-n) will be described in detail. As shown in FIG. 4 (a), the source communication slave station transmits the above-mentioned communication data after establishing a line connection to the first relay station 1 (SA1), and receives the communication data. The first relay station 1 returns a reception completion (ACK) signal as a reception acknowledge signal to the transmission source radio station (SA2).

  The first relay station 1 transmits the communication data after establishing a line connection to the second relay station 2 based on the route information included in the received communication data (SA3). The second relay station 2 that has received the communication data returns a reception completion (ACK) signal to the first relay station 1 (SA4), and if there is another next relay station based on the route information, the relay is performed. If not, the communication data is transmitted to the first communication master station (SA5).

  The reception completion (ACK) signal returned from the second relay station 2 to the first relay station 1 is relayed by the first relay station 1 that has received it and transmitted to the transmission source communication slave station. (SA6). By repeating such a series of procedures, the communication data is transmitted from the source communication slave station to the first communication master station which is the final destination radio station, and reception from the first communication master station is completed ( ACK) signal is transmitted to the source communication slave station (SA7, SA8, SA9).

  The reception completion (ACK) signal includes the route information set in the opposite direction to the route information included in the communication data and the relay station that has received the communication data so that the relayed wireless station and the success or failure of the relay processing can be identified. This is composed of an address and reception completion data, and a reception completion (ACK) signal from each relay station and the first master station is relayed to the transmission source communication slave station based on the route information in the reverse direction to the route information of the transmission data.

  The source communication slave station confirms that the communication data has arrived at the first communication master station safely by analyzing the reception completion (ACK) signals from the returned relay stations and the first communication master station. It is configured so that the transmission process for the event information is terminated after waiting for such completion of the incoming call.

  As shown in FIG. 4B, each relay station that has received the communication data cannot establish a line connection to the next relay station based on the route information, or a reception completion signal is received from the next relay station. When a communication error that has not been confirmed within a predetermined time has occurred, retry is performed a predetermined number of times, and when the communication error is not recovered, reception is not completed as a transmission error signal by the relay destination relay station (NAK) A signal is transmitted (SA10).

  The reception incomplete (NAK) signal is composed of route information set in the opposite direction to the route information included in the communication data, the address of the relay station that transmitted the communication data, and the reception incomplete data. The corresponding incomplete reception (NAK) signal is relayed to the source communication slave station based on the route information in the reverse direction to the route information of the transmission data (SA11).

  Based on the received incomplete reception (NAK) signal, the transmission source communication slave station determines that communication data is not transmitted to the communication master station because a failure has occurred in a specific relay station, and includes that relay station. Other route information that is not present is selected based on the priority order and retransmitted (SA12).

  Based on the communication sequence described above, each communication slave station 30 (30-2 to 30-n) sends to the communication master station 30 (30-1) the number of operations and the operation time of each submersible pump 15 per hour. Operation information such as the water level of the water storage tank 12 and the current value of the submersible pump, for example, one hour of operation information measured and accumulated every minute is transmitted every hour, and an abnormality occurs. Then, event information is transmitted each time.

  Specifically, the hourly notification for transmitting the operation information responds to polling from the communication master station 30 (30-1) to each of the communication slave stations 30 (30-2 to 30-n). An irregular report for transmitting event information transmitted from each communication slave station 30 (30-2 to 30-n) to the communication master station 30 (30-1) is transmitted to the communication slave station 30 (30-2). To 30-n) is spontaneously transmitted to the communication master station 30 (30-1).

  As shown in FIGS. 2 and 3, the notification device 40 connected to the communication device 30 (30-1) serving as the communication master station via the serial transmission line 36 is collected by the communication device 30 (30-1). The operation information and event information of each facility 10 thus received are received via the serial transmission line 36 and are notified to an external device.

  The reporting device 40 includes a reporting control unit 41 in which a microcomputer is incorporated, a reporting destination storage unit 42 that stores a plurality of reporting destinations, a modem 43 in which a voice synthesis unit 44 is built, and the like.

  The report control unit 41 is activated by the communication control unit 31 of the communication master station 30 (30-1), and each manhole pump facility 10 (10-1 to 10-) collected by the communication master station 30 (30-1). The operation information and event information of n) are sequentially reported to a plurality of report destinations stored in advance in the report destination storage unit 42 via the public line 50.

  The report destination storage unit 42 stores telephone numbers of a plurality of managers' mobile phones 51, a fixed phone 52 installed in a management office, a facsimile machine 53, a computer management device 54, and the like.

  The report control unit 41 is activated by the communication control unit 31 and calls each report destination in a preset order every time code data indicating the content of the report is received. If there is a voice message, the data is transmitted if the call destination is the facsimile machine 53 or the management device 54. The notification device 40 may be provided with an e-mail transmission unit, the e-mail address may be stored in the notification destination storage unit 42, and event information may be notified by e-mail.

  The communication control unit 31 reports the operation information of each facility 10 collected regularly to the management device 54 at a preset time interval, and the event information of each facility 10 collected irregularly each time. The telephones 51 and 52 and the facsimile machine 53 are notified. That is, operation information that needs to process a large amount of data is transmitted to the management device 54 and centrally managed, and event information that needs to be dealt with in an emergency such as an accident is transmitted to the telephones 51 and 52 and the facsimile device 53. .

  The event information by voice message is, for example, “An abnormally high water level accident occurred in the third manhole facility” or “The overload condition of the submersible pump that occurred in the fifth manhole facility was recovered”. The event identification information for specifying the event generation facility and the event type information for specifying the event type, that is, individual event information.

  In other words, each of the plurality of facilities 10 scattered in a predetermined area includes a communication control unit 31 that notifies the communication master station 30 (30-1) of event information related to failure occurrence or failure recovery via wireless communication. The master station 30 (30-1) stores, in the storage unit 35, the equipment identification information for specifying the event generating equipment and the event type information for specifying the event type at the time of acquiring the event information. An event notification system that automatically reports individual event information including the equipment identification information and event type information via the notification device 40 is configured.

  The communication master station 30 (30-1) incorporates a delay timer 37 therein, operates a predetermined delay timer 37 when acquiring individual event information, and when the delay timer 37 counts up, the equipment information storage unit When the number of event information stored in 35 is a predetermined number, for example, two cases less than three, the individual event information of the two cases is automatically notified to the report destination, and individually when the predetermined number of cases is, for example, three or more. Instead of event information, it is configured to automatically notify collective event information indicating that a plurality of events are occurring to an administrator's mobile phone 51 or fixed phone 52 as a report destination.

  Collective event information is different from voice messages that include equipment identification information and event type information like individual event information. For example, "Multiple equipment has failed", "Multiple trouble has occurred" ”, Event information that does not include equipment or failure type, such as“ Failure has been recovered in multiple facilities ”, or“ Power outages have occurred in multiple facilities ” Event information including only the type.

  If multiple failures occur almost at the same time, reporting to individual event information each time requires a long time to report to all reporting destinations, so there is a risk that urgent action cannot be taken. Collective event information is reported in order to promptly report only.

  Furthermore, when the number of event information items stored in the facility information storage unit 35 is equal to or greater than a predetermined number and includes a plurality of facilities, the information indicating that an event is occurring in the plurality of facilities is included in the collective event information. By configuring the system to automatically report to the reporting destination, if more than a predetermined number of events reach multiple facilities, the collective event information to be automatically reported, for example, “Multiple facilities have failed. By automatically reporting to the reporting destination, including the fact that an event is occurring at multiple facilities, the administrator can recognize that a failure has occurred over a wide range and can respond quickly. It becomes.

  Hereinafter, the event information reporting operation by the communication master station 30 (30-1) will be described with reference to a timing chart and a flowchart, taking as an example a power outage accident that occurs in a plurality of facilities at approximately the same time.

  First, the first aspect will be described. As shown in FIGS. 5A, 7A, and 7B, the communication master station 30 (30-1) receives the first event information (power failure 1) from the manhole pump facility 10 (10-1). When acquired (SB1), the event information 1 is stored in the equipment information storage unit 35 (SB2), and the delay timer 37 (in this embodiment is set to 5 seconds, but is not limited to this value). .) Is activated (SB3; N, SB4).

  If event information (power failure 2) is acquired from another manhole pump facility 10 (10-2) before the delay timer 37 counts up, that is, within 5 seconds (SB1), the event information 2 is stored in the facility information. Store in the unit 35 (SB2, SB3; Y).

  Thereafter, when the delay timer 37 counts up (SC1; Y), the number of event information stored in the facility information storage unit 35 is referred to, and the stored number is set to a predetermined number (in this embodiment, set to three). However, it is not limited to this value.) Compare the number of cases (SC2).

  In this case, since there are two cases less than three (SC2; N), the report destinations that have set the individual event information (blackout 1, blackout 2) including the name, type of abnormality, and time of occurrence of the blackout The reporting device 40 is activated so as to report to (SC4).

  As shown in FIG. 8A, the notification of the individual event information is managed by the modem 43 by the notification control unit 41 of the notification device 40 by reading the telephone number registered in advance in the notification destination storage unit 42 (SD1). The mobile phone 51 or the fixed phone 52 of the person is controlled to make a call, and detailed information of the event information (power failure 1) and event information (power failure 2) is reported by voice (SD2).

  When the administrator does not respond to the call within a predetermined time, the notification control unit 41 calls the next administrator to make a voice report, and a plurality of administrator's mobile phones 51 and fixed telephones 52 registered in advance. The voice notification is repeated until the notification to is terminated or the predetermined number of retries is reached, and the process is terminated (SD3; Y).

  Moreover, if the communication master station 30 (30-1) acquires event information (power failure 3) from the manhole pump facility 10 (10-3) (SB1), the event information (power failure 3) is stored in the facility information storage unit 35. (SB2), the delay timer 37 is activated (SB3; N, SB4), and before the delay timer 37 counts up, another manhole pump facility 10 (10-4) and manhole facility 10 ( 10-5) When event information (blackout 4) and event information (blackout 5) are obtained (SB1), the event information (blackout 4) and event information (blackout 5) are stored in the equipment information storage unit 35 (SB2). ).

  Thereafter, when the delay timer 37 counts up (SC1; Y), the number of event information stored in the facility information storage unit 35 is referred to and the stored number is compared with a predetermined number (SC2).

  In this case, since there are three event information (SC2; Y), the specific individual event information of the name of the facility where the power failure has occurred, the type of abnormality, and the time of occurrence of the abnormality is not reported, and a plurality of manhole facilities 10 (10 -3-10-5) is notified of collective event information (power failure 3 to power failure 5) indicating that an abnormality has occurred (SC3). It should be noted that when the content of the failure is the same type in the batch event information, a voice message for specifying the failure may be incorporated.

  As shown in FIG. 8 (b), the notification control unit 41 of the notification device 40 reads the telephone number registered in advance in the notification destination storage unit 42 (SE 1) and reports the collective event information by the modem 43. Collective event information (power outage 3 to power outage 5) is voice-reported to the mobile phone 51 or the fixed phone 52 (SE2).

  When the administrator does not respond to the call within a predetermined time, the notification control unit 41 calls the next administrator to make a voice report, and a plurality of administrator's mobile phones 51 and fixed telephones 52 registered in advance. The voice notification is repeated until the notification to is terminated or the predetermined number of retries is reached, and the process is terminated (SE3; Y).

  According to the above configuration, when the number of event information items is less than the predetermined number, accurate event information can be quickly reported to the notification destination, and when the number of event information items exceeds the predetermined number, multiple events occur at the notification destination. You can quickly report what you are doing. The value of the delay timer 37 is preferably set to a value around 5 seconds. If it is too long, the notification will be delayed, and if it is too short, the opportunity to report in the collective event information will be missed.

  Next, the second aspect will be described. As shown in FIGS. 5B, 9A, and 9B, the communication master station 30 (30-1) is configured to update the delay timer 37 every time event information is acquired. ing.

  More specifically, when the communication master station 30 (30-1) acquires event information (power failure 1) from the manhole pump facility 10 (10-1) (SF1), the event information 1 is stored in the facility information storage unit 35. At the same time (SF2), the delay timer 37 (for example, 5 seconds) is activated (SF3).

  If event information (power failure 2) is acquired from another manhole pump facility 10 (10-2) before the delay timer 37 counts up, that is, within 5 seconds (SF1), the event information 2 is stored in the facility information. The delay timer 37 is updated (SF3) while being stored in the unit 35 (SF2).

  Thereafter, when the delay timer 37 counts up (SG1; Y), the number of event information stored in the facility information storage unit 35 is referred to and the stored number is compared with a predetermined number (for example, three). (SG2). In this case, since there are two cases less than three (SG2; N), specific individual event information (blackout 1, blackout 2) of the name of the facility where the blackout occurred, the type of abnormality, and the time of occurrence of the abnormality is reported (SG4). ).

  That is, when the delay timer 37 counts up, the communication master station 30 (30-1) counts the number of event information stored in the storage unit, and when the number is smaller than the predetermined number, many failures occur at the same time. It is determined that the event does not occur, and the individual event information is automatically notified to the report destination. The details of the notification of individual event information are the same as the procedure shown in FIG.

  As shown in FIG.5 (c) and FIG.9 (a), (b), if the communication master station 30 (30-1) acquires event information (power failure 1) from the manhole pump installation 10 (10-1). (SF1), the event information 1 is stored in the equipment information storage unit 35 (SF2), and the delay timer 37 is activated (SF3).

  If event information (power failure 2) is acquired from another manhole pump facility 10 (10-2) before the delay timer 37 counts up, that is, within 5 seconds (SF1), the event information 2 is stored in the facility information. The delay timer 37 is updated (SF3) while being stored in the unit 35 (SF2).

  When further event information (power failure 3) is acquired before the delay timer 37 counts up (SF1), the event information (power failure 3) is stored in the facility information storage unit 35 (SF2), and the delay is delayed. The timer 37 is updated (SF3).

  Similarly, when event information (power failure 4) and event information (power failure 5) are acquired (SF1), the event information (power failure 4, power failure 5) is stored in the facility information storage unit 35 (SF2), and further delayed. The timer 37 is updated and activated (SF3).

  Thereafter, when the delay timer 37 counts up (SG1; Y), the number of event information stored in the facility information storage unit 35 is referred to, and the stored number is compared to a predetermined number, for example, three or more. (SG2).

  In this case, since there are five pieces of event information (SG2; Y), a plurality of manhole facilities 10 (10) are reported without reporting specific individual event information of the name, type of abnormality, and time of occurrence of the power failure. -1 to 10-5) is notified of collective event information (power failure 13 to power failure 5) indicating that an abnormality has occurred (SG3).

  That is, when the communication master station 30 (30-1) acquires event information from the manhole pump facility 10 (10-1) of its own station or the manhole pump facility 10 (10-2 to 10-n) which is a communication slave station. Then, without performing automatic notification immediately, the predetermined delay timer 37 is updated and other event information acquired until the delay timer 37 counts up is stored in the facility information storage unit 35.

  In addition, when the number of event information items stored in the facility information storage unit 35 is equal to or greater than a predetermined number, it is determined that a large number of failures occur at the same time, and an event occurs in a plurality of facilities instead of individual event information. The batch event information indicating that it is in the middle is automatically notified to the report destination. Note that the details of the batch event information report are the same as the procedure shown in FIG.

  According to such a configuration, almost all of the event information that occurs almost at the same time and is transmitted from each of the communication slave stations 30 (30-2 to 30-n) is acquired and then sent to the report destination as collective event information. You can report.

  However, for example, when a plurality of manhole pump facilities 10 lose power all at once due to a lightning strike to a substation, etc., each communication slave station 30 (30-2˜ 30-n) Since the delay timer 37 is updated every time the event information is transmitted sequentially, the event information is reported to the administrator's mobile phone or landline until the delay timer 37 finally counts up. There is a risk that the notification will be delayed.

  In the third mode described below, the communication master station 30 (30-1) is further provided with a limit timer 38 in addition to the delay timer 37, and the limit timer 38 longer than the delay timer 37 is obtained when the first event information is acquired. The delay timer 37 is updated every time an event is acquired, and when the limit timer 38 counts up before the delay timer 37 counts up, the batch event information is automatically notified to the report destination. .

  As shown in FIG. 5 (d) and FIGS. 10 (a), (b), and (c), the communication master station 30 (30-1) receives event information (power failure 1) from the manhole pump facility 10 (10-1). (SH1), the event information 1 is stored in the equipment information storage unit 35 (SH2), the delay timer 37 (for example, 5 seconds) is activated (SH3), and the limit timer 38 (this embodiment) Then, it is set to 10 seconds, but is not limited to this value.) (SH4; N, SH5).

  When event information (power failure 2) is acquired from another manhole pump facility 10 (10-2) before the delay timer 37 counts up, that is, within 5 seconds (SH1), the event information 2 is stored in the facility information. The delay timer 37 is updated (SH3) while being stored in the unit 35 (SH2).

  If another event information (power outage 3) is acquired before the delay timer 37 counts up, that is, within 5 seconds after the event information 2 is acquired (SH1), the event information (power outage 3) is acquired as facility information. While storing in the memory | storage part 35 (SH2), the delay timer 37 is further updated (SH3).

  Similarly, when event information (power failure 4) and event information (power failure 5) are acquired (SH1), the event information (power failure 4, power failure 5) is stored in the equipment information storage unit 35 (SH2), and the delay timer 37 Is updated (SH3).

  If the limit timer 38 counts up during such processing (SJ1; Y), the communication master station 30 (30-1) determines that a plurality of event information has been acquired, and the administrator's mobile phone and fixed The telephone is notified as batch event information (power failure 1 to power failure 3) (SJ2), and the delay timer 37 is reset (SJ3). The notification of collective event information is the same as the procedure described in FIG.

  When the delay timer 37 counts up (SI1; Y), the facility information storage unit 35 is referred to (SI2), and the number of event information is less than the predetermined number (SI2; N), so a plurality of manhole facilities 10 (10-4 to 10-5), individual event information indicating that a power failure has occurred (power failure 4, power failure 5) is reported (SI4), and the limit timer 38 is reset (SI5). The notification of the individual event information is the same as the procedure described with reference to FIG.

  In step SI2, if the number of pieces of event information is equal to or greater than the predetermined number, batch notification is executed (SI3), and the limit timer 38 is reset (SI5). The notification of collective event information is the same as the procedure described in FIG.

  When the delay timer 37 is short, the number of acquired event information does not reach the predetermined number, and eventually the individual notification is unavoidable, and the individual notification is repeated, so that the notification time becomes long. When the delay timer 37 is long, the probability that the number of acquired event information is greater than or equal to the predetermined number is increased, and the chance of collective notification is increased. However, when the event is a sporadic event rather than a simultaneous event However, there is a problem that the report is delayed.

  In the third aspect, by configuring the delay timer 37 to be updated every time an event is acquired, if the event occurs sporadically, the probability that the delay timer 37 is updated is low, and early. The delay timer counts up and you can report quickly. On the other hand, if the events occur simultaneously, there is a high probability that the delay timer 37 will be updated, and there is a possibility that the notification will be delayed, but a limit timer 38 longer than the delay timer 37 that was activated when the first event information was acquired. By counting up, collective event information will be automatically notified to the reportee at an early stage.

  In any of the first to third aspects described above, the communication master station 30 (30-1) is first sent from the control unit 22 or the communication slave station 30 (30-2 to 30-n) of its own station. Although an example has been described in which a delay timer that is a reference for determining whether to report individual event information or batch event information is activated when event information is acquired, it is not always necessary to use a delay timer .

  Below, a 4th aspect is demonstrated as such an example. When the communication master station 30 (30-1) first acquires event information from the control unit 22 of the own station or the communication slave station 30 (30-2 to 30-n), the delay timer is not operated. The notification device 40 is activated so as to automatically notify the individual event information to a plurality of notification destinations registered in advance. Thereafter, the communication master station 30 (30-1) continues to store the event information acquired from the control unit 22 of the own station or the communication slave station 30 (30-2 to 30-n) in the facility information storage unit 35.

  When the communication master station 30 (30-1) receives a signal from the notification control unit 41 of the notification device 40 that the notification to each notification destination of the individual event information for the event information received first is completed, When the number of pieces of event information stored in the equipment information storage unit 35 is smaller than the predetermined number, the individual event information that has not been notified is automatically notified to the respective report destinations. Automatically reports the event information that the event is occurring to the report destination.

  For example, as shown in FIG. 6A, when the communication master station 30 (30-1) acquires event information (power failure 1) from its own equipment 10 (10-1), the event information (power failure 1) is obtained. ) In the facility information storage unit 35, and the modem 43 activates the reporting unit 40 so as to voice-report the event information (power failure 1) to the administrator's mobile phone or fixed phone. At this time, the reporting unit 40 reports specific individual event information such as the name of the facility where the power failure occurred, the type of abnormality, and the time of occurrence of the abnormality.

  During reporting by the reporting device 40, event information (power failure 2) is further acquired from the communication slave station 30 (30-2), and the event information 2 is stored in the facility information storage unit 35. Thereafter, when a signal indicating that the notification of the individual event information has been completed is received from the communication control unit 41, it is determined whether or not the number of event information stored in the facility information storage unit 35 is a predetermined number (three) or more. to decide. In this case, since there is one case less than three, individual event information of event information (power failure 2) which is unreported individual event information is reported.

  As shown in FIG. 6B, a signal indicating that the notification of the individual event information has been completed is received from the communication control unit 41, and the number of event information stored in the facility information storage unit 35 is, for example, a predetermined number ( 3) In the case of the above 4 cases, instead of unreported individual event information, batch event information (power outage 2 to 5) that indicates that an event is occurring at multiple facilities is automatically reported to the reporting destination. .

  That is, the event information acquired first in the communication master station 30 (30-1) is immediately and automatically notified as individual event information immediately, and the event information acquired in the communication master station 30 (30-1) during the automatic notification. Is stored in the facility information storage unit 35. The communication master station 30 (30-1) counts the number of event information stored in the storage unit at the end of the automatic notification, and when the number is smaller than the predetermined number, it is not an event in which many failures occur simultaneously. The individual event information is automatically reported to the report destination. In addition, when the number of event information items stored in the facility information storage unit 35 is equal to or greater than a predetermined number, it is determined that a large number of failures occur at the same time, and an event occurs in a plurality of facilities instead of individual event information. The batch event information indicating that it is in the middle is automatically notified to the report destination.

  In the above description, a plurality of modes in which collective event information is transmitted are described by taking an example of a power outage accident that occurs in a plurality of facilities almost at the same time. The event that occurs in the facility can also be applied to abnormalities other than power outages. Further, the present invention is not limited to the case of event information of the same type, but can also be applied to cases where different event information occurs at almost the same time in a single or a plurality of facilities. Furthermore, the event information includes not only the occurrence of an abnormality but also recovery from the abnormality.

  In the first to third aspects described above, the communication master station may be configured to activate a delay timer when acquiring event information only when the acquired event information is specific event information. . When the delay timer is not activated except for specific event information, individual event information is automatically notified to the report destination.

  Since there is a low probability that various failures will occur in multiple facilities at the same time, and failures that occur simultaneously in multiple facilities are limited, it seems to occur sporadically when the delay timer is operated uniformly. Will delay the reporting of important events.

  Therefore, by operating the delay timer only for failures that occur at the same time in multiple facilities, it is possible to report as batch event information, but events that occur sporadically can be quickly identified as individual event information. It becomes possible to automatically report to the report destination.

  The occurrence of power outage accidents, recovery, abnormally high water levels due to natural disasters such as torrential rain, etc. are suitable examples of specific event information.

  In any of the first to fourth aspects described above, the communication master station 30 (30-1) may receive event information of the same type as the event information notified by the automatically notified collective event information thereafter. It is also possible to configure so that collective event information and individual event information corresponding to the event information are not automatically reported. This is to avoid congestion of the line due to reporting redundant information.

  Further, in any of the first to fourth aspects described above, a new event occurs while the communication master station 30 (30-1) is reporting to each report destination of the batch event information. There is a case. In such a case, when the communication master station 30 (30-1) finishes reporting the collective event information to each report destination, it is stored in the facility information storage unit 35 after the start of reporting of the collective event information. When the number of unreported events is less than the predetermined number, the individual event information is automatically notified to the respective report destinations, and when the number of the unreported events exceeds the predetermined number, a plurality of events are occurring instead of the individual event information. It is preferable that the collective event information is automatically notified to the report destination.

  Usually, a plurality of managers are often set as report destinations, and it takes, for example, several minutes to several tens of minutes before reporting of collective event information to all managers is completed. When new event information is accumulated by the end of the collective event information report to all administrators, the same process, that is, the individual event information report process and the collective event information report process are accumulated, After reporting the collective event information to all managers, reporting of unreported event information is repeated, resulting in poor efficiency.

  For example, in the third aspect described above, the processes of steps SH1 to SH5, steps SI1 to SI5, and steps SJ1 to SJ3 are repeated while reporting the batch event information, and unreported event information is accumulated in the facility information storage unit 35. If they are processed in order, the notification time becomes longer.

  Therefore, when the number of unreported events accumulated in the storage unit during reporting of batch event information is less than a predetermined number, individual event information is automatically notified to the notification destination, and when the number of events exceeds the predetermined number, Alternatively, unreported event information can be reported efficiently by automatically notifying the report destination of batch event information indicating that a plurality of events are occurring.

  The collective event information is information for promptly reporting to the report destination that a plurality of events are occurring. For this reason, the administrator who is notified of the collective event information is not aware of the equipment identification information and event type information that is reported in the individual event information. There is a problem that details cannot be grasped and appropriate measures cannot be taken.

  Therefore, when the communication master station 30 (30-1) receives a request for inquiry of individual event information from a report destination or a reference destination via the notification device 40 at the time of automatic notification of collective event information or after automatic notification, The individual event information stored in the storage unit at the time is preferably configured to be automatically notified by voice or FAX via the notification device 40 to the notification destination or the inquiry destination device for which the inquiry is requested.

  Specifically, at the end of the voice notification of the collective event information reported from the reporting device 40, “To confirm detailed individual event information, press“ # 1 ”. When the notification device 40 detects that the “# 1” key of the telephone is pressed by the administrator who has received the notification, it determines that a request for inquiry of individual event information has been made, Individual event information is automatically reported to the report destination by voice.

  When receiving a signal indicating that a request for reporting individual event information has been detected from the reporting device 40, the communication master station 30 (30-1) stores a plurality of event information stored in the facility information storage unit 35 in the order of acquisition. The individual event information is generated by sorting in the order of the equipment number or by the event type, and then the notification device 40 is activated, and the individual event information corresponding to the notification request is voice-reported. At this time, when a plurality of pieces of event information include items corresponding to the same abnormality, it is preferable to sort by event type, and when a plurality of pieces of event information correspond to different abnormalities, it is preferable to sort in order of equipment number. .

  Further, in preparation for the case where the report destination is a fixed telephone with FAX, when the notification device 40 detects that the “# 1” key of the telephone is pressed by the administrator who has received the report, “detailed individual event information” To confirm by fax, press “# 2”. When the administrator who has received the notification detects that the “# 2” key of the telephone is pressed, the administrator determines that an individual event information inquiry request has been made, and the administrator When the start button is pressed, individual event information is faxed to the report destination.

  In any case, when the reporting device 40 determines that a request for inquiry of individual event information has been made, a message for confirming and inputting the telephone number or FAX number of the reference destination may be added. Furthermore, you may comprise so that the audio | voice message for specifying the specific manhole facility which the administrator has jurisdiction may be added, and the separate event information with respect to a specific manhole facility may be reported.

  As described above, when a request for inquiry of individual event information is received from a report destination or a reference destination via a notification device at the time of automatic notification of batch event information or after automatic notification, the communication master station stores the storage unit at that time. The individual event information stored in is automatically notified to the report destination or the query destination for which the inquiry is requested via the report device. As a result, the latest individual event information can be confirmed at the report destination or the inquiry destination.

  Furthermore, the administrator who is notified of the collective event information may then make a call to the notification device.

  Note that by preparing a plurality of lines drawn into the notification device 40, a line that is called from the notification device 40 and a line that is called from the administrator may be separated.

  Further, when the communication master station 30 (30-1) automatically reports collective event information including events of the same type, a single or a plurality of manhole pumps after a predetermined time has elapsed since the acquisition of the latest event information. You may comprise so that the event fixed information to the effect that the event which generate | occur | produced in the installation 10 was fixed may be reported automatically. The predetermined time is the time required for all transmissions or a certain margin for the time when the communication slave stations 30 (30-2 to 30-n) sequentially transmit to the communication master station 30 (30-1). It is time to expect.

  The communication master station 30 (30-1) automatically reports collective event information composed of events of the same type, and event information that occurs all at once at the same time after a predetermined time has elapsed since the acquisition of the latest event information. Are acquired, and the event that occurred in one or more facilities has been confirmed, that is, it is determined that all the events have been acquired, and the event confirmation information is automatically reported. As a result, it is possible to confirm that a new event does not occur in the report destination to which the event confirmation information is automatically reported.

  Furthermore, when the communication master station 30 (30-1) automatically reports collective event information including an event related to failure recovery, individual event information related to an event whose type is different from the event related to failure recovery of the equipment recovered from the failure is provided. It may be configured to add and automatically report.

  If comprised in this way, when event number memorize | stored in the equipment information storage part 35 is more than a predetermined number, collective event information will be notified from the communication master station 30 (30-1), but collective event information is out of order. In the case of information including an event related to recovery, there may be a case where another failure caused by the failure has occurred in the facility stored in the facility information storage unit 35 as having been recovered from the failure.

  For example, when the level of sewage rises at the time of a power outage and the submersible pump is activated by the control unit 22 when power is restored, the submersible pump activated under a high water supply condition with a low lift and a large capacity will be Abnormalities may occur. In such a case, if the collective event information that “the failure has been recovered in a large number of facilities” is notified, there is a possibility that an abnormality such as an overload of the submersible pump may not be noticed.

  Even in such a case, individual event information related to an event (for example, pump overload) whose type is different from an event (for example, a power failure) related to failure recovery of equipment recovered from a failure is automatically reported. The administrator who is notified of the individual event information can quickly take appropriate measures. At this time, it is easier to understand by first reporting the event occurrence information and then reporting the recovery information.

  Furthermore, the event occurrence equipment name may be added to the collective event information or the event confirmation information to automatically report. If configured in this way, the administrator who has been informed can grasp in which facility the single or multiple events are occurring or the event has been confirmed. Predictions, prevention, countermeasures, etc. can be performed appropriately.

  In the embodiment described above, the configuration in which one communication device 30 is set as the communication master station and the communication master station is provided with the notification device has been described. Reliability can be improved by providing the communication slave station with a reporting device so that one can be replaced with the communication master station.

  For example, when it is detected that communication with the communication master station is not established for a predetermined time, it is determined that the communication master station is out of order and operates as the communication master station. In preparation for such a case, route information for the alternative communication master station may be stored in the route information storage unit 32.

  In the above-described embodiment, the manhole pump facility has been described as an example of a plurality of distributed processing facilities. However, the processing facility to which the present invention is applied is not limited to this, and a plurality of processing facilities scattered in a predetermined area. It can be applied to various processing facilities that need to monitor the facilities.

  The above-described embodiment is merely an example of the present invention, and it goes without saying that the specific configuration of each block can be changed and designed as appropriate within the scope of the effects of the present invention.
