Description

  The present invention relates to a notification system, a notification device, a server, and a notification confirmation method for sending notification information to a notification checker using a notification device and a server, and notifying the notification device of confirmation information performed by the notification checker .

  2. Description of the Related Art There are known a reporting system and a monitoring system for reporting to a manager from a reporting device using a reporting device having an information processing function and a communication line, and notifying a response to the notification to the reporting device as a reception confirmation.

  Such a notification system and a monitoring system are described in Patent Documents 1 to 3, for example.

  In Patent Document 1, when an external input device (sensor group) is connected to a general personal computer and the personal computer detects a fire or an intruder using the external input device, an administrator (report confirmer, report A notification system (notification device) is described in which a notification terminal (mobile phone) of a person who receives the notification is notified (notified) using e-mail. Also disclosed is a technique for operating an output device using electronic mail as a key.

  Patent Document 2 discloses abnormality information and reception confirmation information to a small monitoring portable device (communication terminal) via an Internet line or a telephone line by using a system management unit (report device) and an external circuit connection unit. A remote system monitoring device that can transmit the above is described. It also describes that a user of a monitoring small portable device notifies a URL or a telephone number as information for reception confirmation so that reception confirmation (response) can be easily performed. Further, it is also described that when the administrator accesses the URL or makes a call to a telephone number using a small monitoring portable device, it is identified that the reception has been confirmed.

  Patent Document 3 uses a monitoring device (report device) and a mail server to send an e-mail to an administrator's notification terminal (terminal device, mobile phone) when an alarm is detected. A monitoring system is described in which the response content (reply content) of the terminal is analyzed by a monitoring device, and the administrator confirms that the alarm has been confirmed. Also, response detection that identifies identification information (unique information identifying an alarm) together with alarm information (information indicating an alarm) in the e-mail and identifies that the received e-mail is a response to the transmitted alarm Techniques for processing are also disclosed.

  It is important that the report is reliably communicated to the report recipient. Also, it is important that the report can be recorded. In order to solve such a problem, the notification system, the monitoring system, the monitoring device, and the notification device (hereinafter collectively referred to as the notification device) described in Patent Documents 1 to 3 are used to report using electronic mail. Technology is becoming mainstream. Furthermore, a technique for confirming that an administrator has received an e-mail is disclosed.

  However, the reporting devices of Patent Documents 1 to 3 are realized by a complicated system such as a combination of a personal computer and a mail server. The reporting device has a necessity to operate in an emergency. That is, the reporting device is resistant to power outages and disasters, and is required to operate stably for a long time.

  Although the notification device described in Patent Document 1 can detect an intruder or a fire and notify the administrator's mobile phone using an e-mail, the notification device cannot confirm the reception of the administrator. Further, since the monitoring device is realized using a personal computer, it cannot be driven for a long time. Furthermore, it does not operate when a breaker is dropped by a power failure or by an intruder. Moreover, since a general personal computer is used, it is not suitable for maintenance.

  Although the notification device described in Patent Document 2 can monitor a monitoring target system and send information for reception confirmation together with abnormality information to a monitoring small form device when a problem occurs, the reception confirmation is performed manually by an administrator. There is a lack of certainty because it is necessary to make a phone call or make a call. In addition, even if the notification device is accessed to the notified information for reception confirmation, it cannot be identified whether the access is from the administrator.

  Although the notification device described in Patent Document 3 notifies the administrator of an alarm by e-mail and can authenticate the e-mail of the reception confirmation transmitted by the administrator, in order to send and receive e-mail via the internal mail server, It does not work due to internal mail server trouble or power failure. In addition, since the monitoring apparatus repeatedly performs mail confirmation on the mail server until reception confirmation can be performed, the processing burden on the reception apparatus and the mail server increases. Furthermore, since the system is large and complicated, it is not suitable for operation and maintenance.

  The reporting device is also desired by individuals, small businesses, schools, etc., and it is desirable that the reporting device be easy to install, operate and maintain. In addition, a strong notification device is desired in the event of a power failure or disaster.

  The present invention has been made in view of the above problems, and an object thereof is to provide a notification device that is easy to install, operate, and maintain.

  Yet another object is to provide a strong notification device in the event of a power failure or disaster.

  The notification system of the present invention is a notification system that uses a notification device and a server to notify a notification to a person who confirms the notification using an electronic mail, wherein the notification device uses a public telephone line network as an electronic report. Means for transmitting mail, means for identifying an acoustic signal transmitted during a voice call via the public telephone line network, the server receiving means for receiving an email sent as a report, Means for receiving information for confirming confirmation from the confirmer; means for identifying that the received e-mail has been confirmed by the confirmer; and means for transmitting the identification result as an acoustic signal to the notification device It is characterized by providing.

  The operation of the notification system will be described below with reference to FIGS.

  FIG. 5 is a sequence diagram showing a communication flow of the notification system.

  The notification device 100 detects that the notification sensor or the notification button has been pressed, and transmits an e-mail in which the notification information is described as a notification process to the confirmer terminal 200 and the reception confirmation server 300 (step S501).

  The confirmer confirms the e-mail transmitted as the report received by the confirmer terminal 200, and performs an operation previously determined as a confirmation process for the report. At this time, the confirmer terminal 200 presents the e-mail received from the reporting device 100 to the confirmer, performs a report confirmation process indicating that the report has been confirmed by an operation of the confirmer, and confirms reception in a predetermined format. An e-mail is transmitted to the server 300 (step S502).

  When the reception confirmation server 300 receives an e-mail transmitted as a notification from the notification device 100 and an e-mail transmitted as a reception confirmation from the confirmer terminal 200, the reception confirmation server 300 performs a notification reception confirmation process on the communication device. The generated acoustic signal is transmitted via the public line network (step S503).

  The communication device 100 detects the acoustic signal transmitted from the reception confirmation server, identifies that the report sent by e-mail has arrived at the report confirmer, and ends the report confirmation process (step S504).

  FIG. 6 is a flowchart showing notification processing performed by the notification device 100.

  The control unit 110 of the notification device 100 detects a notification signal detected by the sensor input unit 120 or a notification signal from the notification sensor (step S601).

  The control unit 110 refers to the report destination table stored in the report destination storage unit 141 of the RAM 140 by detecting the report signal, acquires various types of information associated with each sensor that has issued the report, and also sends a report destination ( The e-mail address for sending the notification is determined (step S602).

  The control unit 110 generates information such as the content of the report, the date and time of notification, the device number (ID), the installation position of the device, and the like in the form of an e-mail and records the information in the sending storage unit 142 and the public telephone line An e-mail is transmitted to the notification destination via the network 820 (step S603).

  The control unit 110 starts measuring the time from the date and time when the e-mail is sent using the timer unit 160, and waits until there is a reception confirmation from the reception confirmation server 300 (step S604).

  FIG. 7 is a flowchart showing a confirmation process of a report performed by the confirmer terminal 200.

  The control unit of the confirmer terminal 200 receives an email as a report from the reporting device 100 (step S701).

  The control unit of the confirmer terminal 200 presents the e-mail that is the received report to the confirmer, identifies that the report has been confirmed by the confirmation operation of the confirmer, and sends the e-mail that includes the reception confirmation information in a predetermined format. It transmits to the reception confirmation server 300 (step S702).

  FIG. 8 is a flowchart showing notification reception confirmation processing performed by the reception confirmation server 300.

  The control unit of the reception confirmation server 300 uses the communication control unit 310 to receive an e-mail including notification information transmitted from the notification device 100 (step S801).

  The control unit of the reception confirmation server 300 temporarily stores the notification information in a storage device with a built-in report information, and waits (step S802).

  The control unit of the reception confirmation server 300 receives an email including the reception confirmation information transmitted from the confirmer terminal 200 (step S811).

  The control unit of the reception confirmation server 300 collates the contents of the reception confirmation information with the primary stored report information when there is primary stored report information (step S812).

  As a result of the collation, the control unit of the reception confirmation server 300 confirms that the information is the same (confirmed reception of the notification) (step S813).

  If the collation result is NG, the control unit of the reception confirmation server 300 deletes the reception confirmation information and stands by (step S814).

  When the collation result is OK, the control unit of the reception confirmation server 300 uses the acoustic transmission / reception unit 312 provided in the communication control unit 310 and reports based on the transmission destination table stored in the transmission destination storage unit 320. A call is made (dial) via the public telephone line network 820 to the reporting device 100 that has performed the notification, and a reception confirmation notification is transmitted to the connected reporting device 100 using an acoustic signal (step S815). ).

  After transmitting the reception confirmation notification, the control unit of the reception confirmation server 300 deletes the primary stored notification information and waits until a new notification is notified (step S816).

  FIG. 9 is a flowchart showing processing after notification performed by the notification device 100.

  The control unit 110 of the reporting device 100 stands by after receiving the notification process until reception confirmation by an acoustic signal is received (step S901).

  When receiving the reception confirmation, the control unit 110 records the notification result as OK in order to indicate that the notification result has reached the confirmer (step S902).

  The control unit 110 clears the reception confirmation waiting timer (step S903).

  Control unit 110 measures a reception confirmation timer until reception confirmation is received, and compares it with a predetermined allowable time until reception confirmation to determine whether it is within an allowable range. If it is within the allowable range, it waits (step S904).

  In the case of timeout, the control unit 110 records the report result in NG in order to indicate the possibility that the report has not reached the administrator (step S905).

  Control unit 110 acquires a predetermined retransmission setting for the notification. If there is no retransmission setting, the process shifts to a standby state (step S906).

  If there is a retransmission setting, the control unit 110 performs the notification process again, and sends an email as a notification to the confirmer terminal 200 and the reception management server 300 (step S907).

  The control unit 110 uses the timer unit 160 to start measuring time from the date and time when the re-sent e-mail is sent, and shifts to a standby state (step S908).

  In this way, the notification device 100 can perform confirmation processing with the acoustic signal that the confirmer has confirmed the notification issued by itself.

  Further, it is not necessary to provide a mail receiving function in the reporting device 100, and measures such as deletion of spam mail and virus mail are not required.

  Furthermore, even when a power failure occurs, the built-in battery and public telephone line network can be used to perform notification processing. This is because, in general, a condominium exchange such as a router or modem stops at the time of a power failure, so that IP network communication such as transmission of e-mail becomes impossible. However, the present invention includes a battery and a communication control unit, Can be transmitted. The public telephone line network can be used even during a power failure.

  Next, a second embodiment will be described.

  Since the basic configuration of the second embodiment is the same as that of the first embodiment, description thereof is omitted. In the first embodiment, the reception server 300 compares the notification information sent from the notification device 100 as an alarm with the reception confirmation information sent from the confirmer terminal. On the other hand, in the second embodiment, the notification device 100 that is the notification source is specified using the email address of the email.

  In place of the process of step S802 in FIG. 8, the reception confirmation server 300 refers to the destination table and identifies the reporting device 100 that has reported from the email address. Next, instead of the process of step S812 in FIG. 8, the reception confirmation server 300 uses the pre-recorded e-mail address of the confirmer terminal 200 and the e-mail address of the e-mail containing the received reception confirmation information. Query to determine receipt confirmation. Thereafter, a reception confirmation notification is transmitted to the wireless terminal 100 via the public telephone line network 820.

  In this way, since the alarm sender and the confirmer can be identified based on the e-mail address, the amount of report information described can be reduced.

  Next, a third embodiment will be described.

  Since the basic configuration of the third embodiment is the same as that of the first embodiment, description thereof is omitted. In the first embodiment, the reception server 300 transmits a reception confirmation notification using a pre-registered destination table. On the other hand, in the third embodiment, the telephone number to the notification device 100 and the contents of the acoustic signal for reception confirmation are described in the email transmitted as the notification, and the reception confirmation server 300 is used using these information. Performs a reception confirmation notification.

  The control unit 110 of the notification device 100 is an e-mail in which a telephone number and an acoustic signal for reception confirmation are described as notification information to the reception confirmation server 300 when an alarm is generated based on information recorded in the RAM 140 in advance. Is generated.

  The control unit of the reception confirmation server 300 analyzes the electronic mail received from the notification device 100 and acquires a telephone number described as the notification information and an acoustic signal for reception confirmation. When the receiving server 300 receives the e-mail from the confirmer terminal 200 and confirms the alarm, the receiving server 300 uses the acquired telephone number and an acoustic signal for confirmation of reception to report via the public telephone network 820. A reception confirmation notification is transmitted to the device 100.

  Note that the information of the confirmer terminal 200 may be described in the report information and used for confirmation of reception confirmation.

  In this way, it is not necessary to have a table in which telephone numbers and the like are registered in advance in the reception confirmation server, and a new reporting device can be added to an existing reporting system only by setting the reporting device alone. This reduces the burden on the service provider and greatly increases the scalability of the service providing method.

  Next, a fourth embodiment will be described.

  Since the basic configuration and operation are the same as those of the first embodiment, description thereof is omitted. In the fourth embodiment, the processing contents when the notification times out to the email transmitted from the notification device 100 to the reception confirmation server 300 as an alarm are described.

  In this way, the receiving server 300 automatically contacts, for example, the emergency response destination described in the destination table after another period of time during which the confirmer cannot confirm the report, or another confirmer. You can forward the report to

  In addition to the above embodiment, for the security effect of the e-mail from the confirmer terminal 200, there is also a form for confirming reception using a password and a form for transmitting notification information using only the subject (title) column of the e-mail. Has a noticeable effect.

  The notification device 100 transmits a unique URL (a URL used for one notification or one notification device) to the reception confirmation server 300, and the reception confirmation server 300 uses the unique URL for reception confirmation. The confirmer can also confirm the reception by using the unique URL described in the e-mail sent as an alarm.

  The public telephone line network of the above embodiment is described as ADSL or ISDN. However, other public telephone line networks may be used as long as they can send e-mails and receive calls. Alternatively, a mobile phone, Dopa (registered trademark), or the like may be used. In this case, an e-mail may be sent using a dial-up function, or an e-mail may be sent using a packet communication function possessed by a PHS, a mobile phone, or Dopa.

  In addition, the reporting device according to the embodiment has been described as not having a mail receiving function, but may have a mail receiving function. In this case, maintenance and maintenance can be facilitated by incorporating a function for automatically deleting unnecessary electronic mail (such as spam).

  In addition, the notification device according to the embodiment may be realized using an OS or the like as necessary. In this case, an auxiliary storage device such as an HDD or a flash ROM may be provided and operated.

  As described above, according to the present invention, the notification device only connects the power source and the telephone line, and can be installed without complicated setting processing.

  Similarly, by omitting the mail receiving function, the operation of accessing the mail server at all times is unnecessary, and the processing load on the control unit is remarkably reduced.

  Furthermore, there is no need to assign an IP address to the reporting device, and the burden on the installation and maintenance of the administrator of the reporting device is reduced.

  In addition, maintenance can be restored to the initial state only by rewriting (writing back) the contents of the RAM.

  That is, according to the present invention, it is possible to provide a notification device that is easy to operate and maintain. Similarly, according to the present invention, it is possible to provide a strong notification device at the time of a power failure or disaster.
