  The notification target terminal 90 is a fixed telephone set of an external organization that manages the manhole device 51 or a maintenance contractor, or a mobile wireless terminal device possessed by a person in charge of the department or external organization. Each mobile phone is composed of a mobile phone and has an e-mail transmission / reception function. Usually, there are a plurality of notification target terminals corresponding to a plurality of persons in charge of managing the manhole apparatus 51, and the terminal type is not limited to a telephone, but an electronic mail receiving function such as a personal computer or a handy terminal. It may be configured by a pair of a terminal equipped with a telephone capable of voice communication such as a portable telephone. In the above description, an example is shown in which a radio station is relayed by a small area communication system using a new simple radio system, and a specific radio station is connected to a public line as a radio master station. You may comprise so that it may connect with a line | wire.

  The operation of the plant event management system including the plurality of plants, the event management device 80, and the notification target terminal 90 will be described with reference to FIGS. When event occurrence information such as the occurrence of an abnormality is transmitted to the event monitoring means 81 from the packet communication terminal 15 of the manhole device 51, which is an example of a plurality of plants, via the packet communication network T, history data for the occurrence event is obtained. While being managed by the history management unit 85, event information such as event contents and event occurrence time is reported to the notification target terminal by the event reporting unit 82. When it occurs (S1), the voice notification timer is set, and the notification target terminal group number is set in the event identification flag for identifying the generated event to prepare for notification processing (S2, S3). When no event occurs Whether notification processing for events that occurred in the past has ended It is determined whether or not (S12), includes the generation of a new event returns to the step S1 if the termination, notification process executes the alarm process if not ended (S3).

  The event identification flag is composed of n counters corresponding to the number of events that can be simultaneously processed, and the notification target terminal group number is written in each counter from the counter number 1 to the counter number n in the order of occurrence. The notification target terminal group number is a value stored in advance in the history management unit 85 and read by the event notification unit 82 when an event occurs. The most significant bit of each counter is used as an e-mail notification completion flag indicating whether or not e-mail notification has been completed, and the notification target terminal group number is written in the lower bits. For example, an 8-bit counter can handle up to 128 notification target terminal group numbers, but this value is appropriately set depending on the scale of the system.

  In the notification process by e-mail in steps S3 to S6, first, an event identification flag, that is, a flag 1 routine at the time of e-mail notification process for the event that occurred first with reference to the counter number, A flag 2 routine is executed during the notification process, and a flag n routine is executed during the notification process for the event that occurred last. In each routine, the same processing is executed, and when the notification processing by e-mail ends after each flag (counter) is set, an e-mail communication completed flag is set as shown in step S6. Accordingly, the notification by the e-mail identified by the e-mail notification flag is executed preferentially from the routine corresponding to the oldest event identification flag that has not been completed.

  In the e-mail notification process, it is first determined whether or not the e-mail transmission has ended (S4). If not, the e-mail transmission unit 83 stores a plurality of notification objects stored in the history management unit 85. E-mail transmission processing is executed in order toward the mobile phone 90 owned by the user (usually a plurality of mobile phones) (S5), and when the transmission processing is completed, the e-mail notification flag is set (S6).

  When the timer counts up (S7), the voice notification means 84 makes a voice call based on the telephone number of the mobile phone 90 owned by the notification target person set for each event stored in the history management means 85. The notification process is executed (S8), and when finished, the values of the event identification flag and the e-mail notification flag are reset (S10). Whether or not an e-mail transmission process for another event is necessary during the timer counting or during the voice notification process is determined based on the value of the event identification flag (S11), and if necessary, the process proceeds to step S3. If it is not necessary, it waits in step S1. After shifting to step S3, as described above, the routine moves to a routine corresponding to an event identification flag that requires an email transmission process based on the value of the event identification flag, and an email transmission process is executed. The voice notification means 84 is composed of voice synthesis means for generating voice based on a preset message and an automatic dialer for making a call to the telephone number of the call destination.

  In this way, when a plurality of events occur while the voice notification timer is counted up, the notification process by email is executed in preference to the voice notification process, and after the voice notification timer is counted up, that is, by email After the notification process is completed, a voice notification is made by the voice notification means 84 (S8). At this time, the voice notification unit 84 determines to make a single voice report for the duplicated destinations in the email destination list for each occurrence event by the email sending unit 83, and duplicates. The voice notification process is executed while skipping the telephone number. Therefore, when a plurality of events occur within a certain time (set value of the voice notification timer), it is possible to reduce the number of voice notification processes that require time and cost. In the voice notification process, if there is no response within a predetermined time, the next notification destination is called, and the call processing to the other notification destinations in the notification target terminal group is retried a set number of times. Be controlled.

  In other words, the voice notification unit 84 makes a single voice report to a destination that overlaps with the destination of the email for each event generated by the email transmission unit with respect to an event occurring within a predetermined time. It is configured.

  As shown in FIG. 8, when the e-mail is transmitted by the e-mail transmission means 85 (S21), the owner of the mobile phone 90 has transmitted the e-mail by the incoming call of the telephone notification by the voice notification means 84. When noticed (S22, S23), when the e-mail is opened (S24), a message in HTML format as shown in FIG. 4A is displayed and a URL which is link information to the web server 86 is displayed on the message display screen. Is displayed. When the owner accesses the web server 86 based on the hyperlinked URL (25), the opening confirmation means 87 confirms the telephone number or domain name of the connected device (S26), and sends it to the e-mail destination. When it is determined that the access is from the corresponding mobile phone 90, the opening of the electronic mail is confirmed (S27).

  When the opening confirmation unit 87 confirms the opening, the e-mail transmission unit 83 transmits a reception confirmation message as shown in FIG. The opening confirmation data is recorded in the history management data (S28), and the opening confirmation data can be confirmed from the terminal accessing the web server 86.
