FIG. 10 is a flowchart showing the operation of the notification server device. In FIG. 10, the notification signal determination unit 123 in the central processing unit 102 of the notification server device 11 repeatedly determines whether or not the communication IF unit 101 has received a notification signal (S11). When the communication IF unit 101 receives a notification signal (YES), the received notification signal is output to the central processing unit 102 and notified to the transfer unit 121, the notification signal determination unit 123, and the notification signal recording unit 124. The The transfer unit 121 waits for an instruction from the transfer control unit 122. The notification signal recording unit 124 makes an inquiry to the calendar unit 125, acquires the current year / month / day / hour / minute / second as the reception time, and waits for an instruction from the notification signal determination unit 123.

  The report signal determination unit 123 extracts the IP address from the source IP address unit 32 in the IP datagram 20 of the report signal described later. The notification signal determination unit 123 searches the extracted IP address from the temporary IP address registration table 142 stored in the temporary address storage unit 132 of the storage unit 103 (S12).

  Next, the notification signal determination unit 123 determines whether or not there is a temporary IP address that matches the IP address extracted from the notification signal in the temporary IP address registration table 142 as a result of the search (S13).

  As a result of the determination, if there is a matching temporary IP address in the temporary IP address registration table 142 (YES), the notification signal determination unit 123 transmits the source port number 41 in the IP datagram 20 of the notification signal described later. Retrieve the port number from. The notification signal determination unit 123 searches the registered notification device table 143 stored in the registration notification device storage unit 133 of the storage unit 103 for the extracted port number (S14).

  Next, as a result of the search, the report signal determination unit 123 determines whether or not there is a report device port number that matches the port number extracted from the report signal in the registered report device table 143 (S15).

  As a result of the determination, if there is no matching reporting device port number in the registered reporting device table 143 (NO), the reporting signal determination unit 123 uses the reporting signal received in step S11 to test the reporting device 13. Judged to be a test report signal. Then, the notification signal determination unit 123 registers the port number extracted from the notification signal in the process S14 as the notification device port number in the registration notification device table 143, and notifies the transfer control unit 122 and the fact that the notification signal is a test notification signal. The notification signal recording unit 124 is notified (S16).

  When the notification that the notification signal is a test notification signal is received, the transfer control unit 122 prohibits transfer of the notification message according to the notification information of the notification signal and controls the transfer unit 121 to discard the notification signal. To do. The report signal recording unit 124 registers information related to the report signal received in this process S11 in the report signal reception recording table 144 stored in the report signal storage unit 134 of the storage unit 103, and records a log of the test report signal. .

  On the other hand, as a result of the determination in step S15, if there is a matching notification device port number in the registered notification device table 143 (YES), the notification signal determination unit 123 indicates that the notification signal received in step S11 is in operation. It is determined that the signal is an official notification signal notified from the notification device 13. Then, the report signal determination unit 123 notifies the transfer control unit 122 and the report signal recording unit 124 that the report signal is an official report signal (S17).

  When receiving a notification that the notification signal is an official notification signal, the transfer control unit 122 controls the transfer unit 121 to transfer a notification message corresponding to the notification information of the notification signal. The transfer unit 121 refers to the transfer destination information table 141 stored in the transfer destination information storage unit 131 of the storage unit 103 and transfers a notification message corresponding to the notification information of the notification signal to the transfer destination device 18 of a predetermined destination. To do. The report signal recording unit 124 registers information related to the report signal received in this processing S11 in the report signal reception recording table 144 stored in the report signal storage unit 134 of the storage unit 103, and records a log of the formal report signal. .

  If there is no matching temporary IP address in the temporary IP address registration table 142 as a result of the determination in the process 13 (NO), the notification signal determination unit 123 sends the source port in the IP datagram 20 of the notification signal. The port number is extracted from the number part 41. The notification signal determination unit 123 searches the registered notification device table 143 stored in the registration notification device storage unit 133 of the storage unit 103 for the extracted port number (S21).

  Next, as a result of the search, the report signal determination unit 123 determines whether there is a report device port number that matches the port number extracted from the report signal in the registered report device table 143 (S22).

  As a result of the determination, if there is a matching reporting device port number in the registered reporting device table 143 (YES), the reporting signal determination unit 123 reports the reporting signal received in step S11 from the reporting device 13 in operation. It is determined that the signal is an official notification signal. Then, the report signal determination unit 123 notifies the transfer control unit 122 and the report signal recording unit 124 that the report signal is an official report signal (S23).

  When receiving a notification that the notification signal is an official notification signal, the transfer control unit 122 controls the transfer unit 121 to transfer a notification message corresponding to the notification information of the notification signal. The transfer unit 121 refers to the transfer destination information table 141 stored in the transfer destination information storage unit 131 of the storage unit 103 and transfers a notification message corresponding to the notification information of the notification signal to the transfer destination device 18 of a predetermined destination. To do. The report signal recording unit 124 registers information related to the report signal received in this processing S11 in the report signal reception recording table 144 stored in the report signal storage unit 134 of the storage unit 103, and records a log of the formal report signal. .

  On the other hand, if the result of determination in step S22 is that there is no matching notification device port number in the registered notification device table 143 (NO), the notification signal determination unit 123 indicates that the notification signal received in step S11 has not been tested. It is determined that it is an official notification signal notified from the notification device 13. Then, the report signal determination unit 123 registers the port number extracted from the report signal in the process S14 in the registered report device table 143, and outputs to the output unit 25 that the test is incomplete, and the report signal is the formal report signal. To the transfer control unit 122 and the notification signal recording unit 124 (S24).

  When receiving a notification that the notification signal is an official notification signal, the transfer control unit 122 controls the transfer unit 121 to transfer a notification message corresponding to the notification information of the notification signal. The transfer unit 121 refers to the transfer destination information table 141 stored in the transfer destination information storage unit 131 of the storage unit 103 and transfers a notification message corresponding to the notification information of the notification signal to the transfer destination device 18 of a predetermined destination. To do. The report signal recording unit 124 registers information related to the report signal received in this processing S11 in the report signal reception recording table 144 stored in the report signal storage unit 134 of the storage unit 103, and records a log of the formal report signal. .

  As described above, when the notification server apparatus 11 according to the present embodiment receives the notification signal, first, the IP address of the transmission source accommodated in the received notification signal is the temporary IP address registration table 142 of the temporary address storage unit 132. To determine whether or not the received notification signal is a test notification signal or an official notification signal by determining whether or not it matches the temporary IP address registered in (step S13). Can do.

  If it is determined that it is a test report signal, the report server device 11 registers the port number of the transmission source accommodated in the received report signal in the registered report device table 143 of the registered report device storage unit 133. It is determined whether or not the test for the reporting device 13 that has transmitted the received notification signal has been completed by determining whether or not it matches the reporting device port number that has been received (mainly processing S15). It is possible to judge and recognize whether the test report signal is transmitted from the reporting device 13 indicating completion or the formal report signal transmitted from the reporting device 13 that has completed the test. Therefore, by performing the determination process in this way, the formal notification signal transmitted by the notification device 13 can be processed by the temporary router device 12 before the notification device 13 concludes the service provision contract with the ISP-A. it can. For this reason, by using the temporary router device 12, for example, it is possible to monitor disaster prevention, crime prevention, or the like for a pre-sale dwelling unit in an Internet apartment.

  Further, when it is determined that the notification signal is an official notification signal, the notification server device 11 registers the port number of the transmission source accommodated in the received notification signal in the registration notification device table 143 of the registration notification device storage unit 133. It is determined whether or not the test for the reporting device 13 that has transmitted the received notification signal has been completed by determining whether or not it matches the reporting device port number that has been received (mainly processing S22). It is possible to determine and recognize whether the signal is an official notification signal transmitted from the informing device 13 or an authorized notification signal transmitted from the reporting device 13 that has completed the test. Therefore, by performing the determination process in this way, an untested reporting device 13 can be found.

  Then, the notification server device 11 records the reception of the notification signal, including whether it is a test notification signal or a formal notification signal, in each determination, in the notification signal reception record table 144 of the notification signal storage unit 134. Register with. For this reason, the operator can recognize whether or not a test report signal has been received from the reporting device 13 under test by designating the type flag as “E” and referring to the report signal reception record table 144. The contractor can recognize the test result of the reporting device 13 by notifying the contractor in response to the query of the contractor or voluntarily. Therefore, the contractor only needs to inquire the operator about the test result after the test, so there is no need to contact the start of the test or the contact during the test. Errors such as operational errors and judgment errors are reduced.

  As described above, in the notification server device 11 according to the present embodiment, it is not necessary to provide the notification device 13 with a configuration for distinguishing whether or not the notification signal is a test notification signal. Moreover, it is not necessary to divide the time into the time zone in which the test is performed and the time zone during operation. In the reporting system according to the present embodiment, the reporting server device 11 can automatically distinguish whether or not the reporting signal is a test reporting signal even when the reporting system 1 is in operation. Even during operation of the reporting system 1, the reporting device 13 can be additionally constructed and a test can also be performed.

  Next, the case where the reporting device 13 is constructed and tested in the reporting system 1 having such a reporting server device 11 will be described more specifically.

  When the test of the notification device 13 is performed, first, the operator of the notification server device 11 uses the input unit 104 to input the IP address set in the temporary router device 12 as a temporary IP address. The operator of the notification server device 11 receives a notification from the installer, for example, of the IP address set in the temporary router device 12. When input as a temporary IP address, the reporting server device 11 registers this IP address in the temporary IP address registration table 142 of the temporary address storage unit 132. Further, the operator of the notification server device 11 uses the input unit 104 to input information to be registered in the transfer destination information table 141. Upon receiving this information, the reporting server device 11 registers this information in the transfer destination information table 141 of the transfer destination information storage unit 131.

  On the other hand, the installer installs the reporting device 13, sets an IP address as a private address in the reporting device 13, and stores it in the reporting device IP address storage unit 341. Further, the contractor stores the IP address of the notification server device 11 in the notification server device IP address storage unit 342. Note that either or both of the IP address of the reporting device 13 and the IP address of the reporting server device 11 may be stored in the reporting device 13 at the manufacturing company or the shipping stage.

  The contractor then sets the private address set for the reporting device 13, the IP address assigned by ISP-B according to the service provision contract, the port number for the transfer processing program of the reporting server device 11, the reporting server device 11 of the reporting device 13. Port number (port number assigned to the reporting device 13 to identify the reporting device 13 before and after the NAPT conversion) is set in the temporary router device 12. Upon receiving these information settings, the temporary router device 12 registers the information in the temporary NAPT information table 241 of the temporary NAPT table storage unit 232.

  When the contractor incorporates the reporting device 13 into the reporting system 1 and operates the reporting device 13 to satisfy the predetermined condition in order to test the reporting device 13, that is, in this embodiment, smoke is brought closer to the reporting device 13. The notification device 13 is notified to the notification processing unit 302 that the predetermined condition is satisfied by the detection unit 303, and the IP address of the notification device 13 stored in the storage unit 304 by the notification processing unit 302, A notification signal is generated using the IP address of the notification server device 11 and the port number for the transfer processing program of the notification server device 11 in the notification device 13, and the notification signal is transmitted by the communication IF unit 301.

  The notification signal transmitted from the notification device 13 reaches the hub device 14. When the hub device 14 is a repeater hub, the notification signal is distributed to each port and output to the permanent router device 15 and the temporary router device 12. When the hub device 14 is a switching hub, the notification signal is output to the permanent router device 15 and also to the temporary router device 12 from the mirror port.

  The notification signal received by the permanent router device 15 is discarded without being routed (route selection) because the notification device 13 is not contracted with ISP-A. On the other hand, the notification signal received by the temporary router device 12 is subjected to NAPT using the temporary NAPT information table 241 in the temporary NAPT table storage unit 232, routed, and the ISP-B network 16-b and the Internet 17. To the notification server device 11.

  Here, the NAPT in the temporary router device 12 will be further described.

  FIG. 11 is a diagram illustrating a configuration of an IP datagram of a notification signal. FIG. 11A shows the overall configuration of the IP datagram of the notification signal, and FIG. 11B shows the detailed configuration of the IP header portion and the TCP header portion in the IP datagram of the notification signal.

  First, the configuration of the IP datagram of the notification signal generated by the notification device 13 will be described. For example, as shown in FIG. 11A, the IP datagram 20 of the notification signal includes an IP header portion 21 that accommodates an IP header, a TCP header portion 22 that accommodates a TCP header, and transmission of, for example, notification information. And a data unit 23 for storing data to be processed. The configuration of the IP header part 21 and the TCP header part 22 will be described in further detail. As shown in FIG. 11B, when the IP is version 4, the IP header part 21 has version information, header length, etc. IP header information part A31-a that accommodates the information, a transmission source IP address part 32 that accommodates the IP address of the transmission source of this IP datagram 20, and the IP address of the destination (transmission destination) of this IP datagram 20 Destination IP address part 33 and IP header information part B31-b for accommodating options and padding. The TCP header part 22 includes a transmission source port number part 41 that accommodates the transmission source port number of this TCP packet, a destination port number part 42 that accommodates the destination (transmission destination) port number of this TCP packet, and a sequence number. And a TCP header information unit 43 that accommodates information such as an acknowledgment number.

  Then, in the IP datagram 20 of the notification signal generated by the notification device 13, the source IP address portion 32 contains the IP address of the private address of the notification device 13, and the destination IP address portion 33 has the notification address. The IP address of the server device 11 is accommodated, and the port number for the transfer processing program of the reporting server device 11 is accommodated in the transmission source port number portion 41.

  For example, when the reporting device 13 is specified by the IP address of the reporting device 13 or the reporting device identifier, and as a result, the contents of data such as reporting information stored in the data unit 23 can be specified, the data unit 23 is not necessarily required. Of course, the IP may be version 6.

  Next, the operation of the temporary NAPT unit 222 will be described more specifically with reference to FIG. When receiving and receiving a notification signal having such a configuration of the IP datagram 20 from the notification device 13 via the hub device 14, the temporary NAPT unit 222 first transmits the source IP in the IP datagram 20 of the received notification signal. The IP address and port number accommodated in the address part 32 and the source port number part 41 are extracted. Next, the temporary NAPT unit 222 searches the LAN side NAPT information field 2411 of the temporary NAPT table 241 stored in the temporary NAPT table storage unit 232 of the storage unit 203 based on the extracted IP address and port number. Next, as a result of searching, when the IP address (private address) and port number that match the extracted IP address and port number are searched for in the LAN side NAPT information field 2411, the temporary NAPT unit 222 displays the WAN side NAPT information field 2412. The IP address (global address) and the port number corresponding to this are taken out from. Next, the temporary NAPT unit 222 rewrites the IP address of the transmission source IP address unit 32 with the extracted IP address (global address), and rewrites the port number of the transmission source port number unit 41 with the extracted port number. Then, the temporary NAPT unit 222 notifies the routing unit 221 of the notification signal of the rewritten IP datagram.

  For example, the IP address and the port number accommodated in the transmission source IP address part 32 and the transmission source port number part 41 in the IP datagram of the notification signal received and received from the notification device 13 via the hub device 14 are “192. Assuming that the values are 168.128.12 ”and“ 5000 ”, the temporary NAPT unit 222 searches the LAN side NAPT information field 2411 of the temporary NAPT information table 241 based on the IP address (private address) and the port number. Since the IP addresses (global addresses) and port numbers corresponding to these IP addresses (private addresses) and port numbers are “150.0.0.1” and “30002”, the IP addresses (global addresses) “ 150.0.0.1 The source IP address portion 32, and rewrites each port number "30002" to the source port number 41. Then, the temporary NAPT unit 222 notifies the routing unit 221 of the notification signal of the rewritten IP datagram.

  In this way, the notification signal including the IP datagram in which the IP address of the source IP address unit 32 and the port number of the source port number unit 41 are rewritten is transmitted by the routing unit 221 in the central processing unit 202 of the temporary router device 12. The information is routed and transmitted to the notification server device 11 via the ISP-B network 16-b and the Internet 17.

  And the notification server apparatus 11 which received this report signal performs the process S11, the process S12, and the process S13 according to the process shown in FIG. 10, and judges that the received report signal is the test report signal in the process S13. The process S14 and the process S15 are executed. In the process S16, the received notification signal is determined to be a test notification signal by the notification device 13 that has not been tested, and the port number extracted from the notification signal is stored in the registered notification device table 143. Register as a reporting device port number, prohibit the forwarding of reporting messages according to the reporting information of the reporting signal, discard the reporting signal, and record the test reporting signal log.

  Whether the construction of the reporting device 13 has been normally completed by inquiring the operator of the test result of whether or not the test reporting signal of the reporting device 13 has been received by the reporting server device 11 from the operator. Can be recognized.

  When the tester completes the test for each reporting device 13 and the reporting device 13 that has completed the test detects the detection target and transmits a reporting signal to the reporting server device 11, the reporting signal Is received by the notification server device 11 via the hub device 14, the temporary router device 12, the ISP-B network 16-b and the Internet 17. The notification server device 11 that has received the notification signal executes the processing S11, the processing S12, and the processing S13 according to the processing shown in FIG. 10, and determines that the received notification signal is a test notification signal in the processing S13. As a result of executing step S14 and step S15, it is determined in step S17 that the received notification signal is an official notification signal from the notification device 13 that has completed the test, and a notification message corresponding to the notification information of the notification signal is transferred to the destination device. 18 and record the log of the official notification signal.

  On the other hand, when the operation of the notification device 13 is started and the notification device 13 detects the detection target and transmits the notification signal to the notification server device 11, the notification signal is transmitted to the hub device 14, the permanent router device 15, and the ISP-A. Is received by the notification server device 11 via the network 16-a and the Internet 17. The permanent router device 15 executes NAPT based on the NAPT table 541 shown in FIG. 9B, for example, so that the IP address of the permanent router device 15 is accommodated in the source IP address section 32 of this notification signal. The The notification server device 11 that has received this notification signal executes processing S11, processing S12, and processing S13 according to the processing shown in FIG. 10, and determines in step S13 that the received notification signal is an official notification signal.

  Here, when the reporting device 13 that has transmitted this reporting signal has completed the test, as a result of executing the processing S21 and the processing S22, the received reporting signal in the processing S23 is officially transmitted by the reporting device 13 that has completed the testing. It judges that it is a report signal, transfers the report message according to the report information of the report signal to the transfer destination apparatus 18, and records the log of the formal report signal. In addition, when the reporting device 13 that has transmitted this notification signal has not been tested, as a result of executing the processing S21 and S22, the received notification signal is sent to the formal reporting by the reporting device 13 that has not been tested in step S24. It is determined that the signal is a signal, and the fact that the test is not completed is output to the output unit 105, and a notification message corresponding to the notification information of the notification signal is transferred to the transfer destination device 18 to record a log of the official notification signal.

  In the above-described embodiment, since the port number is used as the identifier of the reporting device 13, the temporary router device 12 is a NAPT router device. However, the identifier of the reporting device 13 is used separately from the port number. In this case, a NAT (Network Address Translation) router device may be used. The NAT router device is a network address conversion router device that mutually converts an IP address between a private IP address and a global IP address. In addition to this, the NAPT router device also converts a TCP or UDP port number. . The NAT router device can support a plurality of nodes having private IP addresses more than the number of global IP addresses, while the NAPT router device supports a plurality of nodes having private IP addresses with one global IP address. can do.

  In the above-described embodiment, the notification server device 11 is configured to transfer the transfer information corresponding to the notification information of the notification signal to the transfer destination device 18 when receiving the notification signal, but instead of the transfer information. The notification information itself may be transferred, or the notification signal itself may be transferred instead of the transfer information. With this configuration, the process of the notification server device 11 can be simplified, and the process can be executed at a higher speed.

  In the above-described embodiment, one transfer destination device 18 is designated for one notification device 13, but a plurality of transfer destination devices 18 are specified for one notification device 13. It may be configured to specify. With this configuration, it is possible to notify a plurality of transfer destination devices 18 that a notification signal has been transmitted from the notification device 13. In this case, the text of the notification message may be changed for each transfer destination device 18. With this configuration, a different response can be executed for each user of the transfer destination device 18. For example, the notification message to be notified to one transfer destination device 18 is a text that notifies only that a notification signal has been transmitted from the notification device 13, and the notification message to be notified to the other transfer destination device 18 is the notification device 13. It is a text to notify that the notification signal has been transmitted from and that the action according to the notification information of the notification signal is promoted. Further, in this case, the transfer destination device 18 is configured so as to return that the communication signal containing the notification message has been received (reception response), and a transfer priority is assigned to each transfer destination device 18. The notification message may be transferred to the transfer destination device 18 according to the priority order until there is a reception response from 18. With this configuration, the notification message can be appropriately transferred.

  Furthermore, in the above-described embodiment, the notification signal reception record table 144 is configured to include the reception time field 1441, the notification device port number field 1442, the notification information field 1443, and the type flag 1444, but as necessary. Further, a field may be provided. For example, there is a transfer correct / incorrect field for registering information indicating whether or not the report message has been successfully reported to the transfer destination device 18. On the other hand, in the above-described embodiment, since the reporting device 13 is one type of fire sensor, the reporting information is specified, so the reporting information field 1443 may be omitted.

  In the above-described embodiment, the notification server device 11 is configured to transmit a notification message to the transfer destination device 18 using electronic mail, but is not limited thereto. Depending on the method of presenting the transfer information, there are various types such as a control signal for outputting a notification message by voice, a control signal for generating an alarm sound, a control signal for emitting alarm light, and a control signal for vibrating.

  In the above-described embodiment, when the operator searches for the test notification signal from the reception record of the notification signal and displays it on the output unit 105, the type flag is designated as “E” and the notification signal reception record table 144 is stored. Although it is configured to search, the notification signal reception record table 144 may be configured not only to specify the type flag “E” but also to specify the time range. In particular, when testing a large number of reporting devices 13, it is possible to quickly search for a test reporting signal transmitted by the target reporting device 13.

  Furthermore, in the above-described embodiment, the operator voluntarily or in response to the inquiries from the installer, the test equipment of the reporting device 13 is configured to be informed to the installer. It is also possible to configure so that the contractor himself / herself can directly confirm the test result of the reporting device 13 by directly accessing the reporting server device 11. With this configuration, the operator's trouble can be saved.

  In the above-described embodiment, if there is no matching reporting device port number in the registered reporting device table 143 in step S15, the reporting signal determination unit 123 sets the port number of the reporting signal in step S16. The report server device 11 is configured to automatically register the information as a report device port number in the table 143. However, the report server device 11 searches the reception record in the report signal reception record table 144 and the test server 11 sends the test report signal from the report device 13 under test. After confirming that it has been received, the port number of the test report signal from the reporting device 13 may be registered in the registered reporting device table 143 as the reporting device port number based on the operator's instruction. Good. With this configuration, only the reporting device port number of the reporting device 13 for which the test has been reliably completed can be registered in the registered reporting device table 143.
