  Next, in step S12, the notification device 10 determines whether a request signal has been received from the reception device 50 during the notification. That is, when the notification device 10 receives an image transmission request signal from the reception device 50, the notification device 10 transmits image data to the reception device 50 accordingly.

  In addition, when it is determined that the notification end request signal has been received from the reception device 50 in step S13, the notification device 10 starts accumulation of image data in the image storage unit 24 as notification end processing in step S14. The process proceeds to preparation for transferring stored image data to the receiving device 50.

  Further, when the reporting device 10 determines in step S15 that it has received the transfer request signal for the stored image data from the receiving device 50, in step S16, the stored image data, the door before the notification when the report button 17 is pressed. The accumulated image data from the time when the opening switch 16 is activated until the communication with the accepting device 50 is established and the accumulated image data pending notification are transmitted to the accepting device 50.

  Furthermore, when the notification device 10 determines that the voice transmission request signal has been received from the reception device 50 in step S17 after the door opening switch 16 is activated, the notification device 10 responds to the reception device 50 in step S18. Send data. At this time, when the notification device 10 receives the notification end request signal, the notification device 10 stops the transmission of the voice data to the reception device 50.

  Furthermore, when it is determined that the suspension is selected by the supervisor during the notification / communication with the accepting device 50 in step S19, the notification device 10 performs the notification suspension processing in step S20 accordingly. Then, the transmission of the image data to the receiving device 50 is interrupted, and the process proceeds to the image data storage process for the image storage unit 24. At this time, the notification device 10 stores the pending image data in the image storage unit 24 for the set number of images related to the storage of image data before the notification button 17 is pressed. The set number of sheets is designated by the accepting device 50 by the set value in step ST7 described above. When the notification device 10 receives the image transmission request signal again from the reception device 50 during the hold state, the notification device 10 shifts to the notification state and transmits the image data to the reception device 50.

[Operation of reception device]
On the other hand, the reception device 50 performs processing as shown in FIGS. 8 and 9 in response to the operation of the notification device 10 as described above.

  That is, as shown in FIG. 8, when the accepting device 50 is activated, in step S31, the accepting device 50 performs activation processing and shifts to a normal state. In the normal state, the accepting device 50 determines whether or not there is a report depending on whether or not the emergency call information is received in step S32, whether or not there is a screen operation by the supervisor in step S33, In addition, the diagnosis processing in step S34 and the diagnosis result in step S35 are determined.

  First, if the receiving device 50 determines in step S32 that there has been a report, in step S36, the receiving device 50 generates the emergency call information and designates the notification device 10 that has been recognized to have received the notification, and the voice data and image A notification device that transmits a transmission request signal for data, further displays a notification on the display 62 in order to notify the supervisor of the emergency notification in step S37, and generates emergency notification information as notification processing in step S38. 10 starts communication.

  Here, as described above, since the communication between the notification device 10 and the reception device 50 has already been established after the door opening switch 16 is operated, the emergency notification system operates when the supervisor operates a predetermined call start switch. At the same time, the supervisor can make a two-way call with the reporter while viewing the image data via the display 62.

  When the reception apparatus 50 shifts to the notification process, the image transmission request signal is transmitted to the notification apparatus 10 in step S51 as shown in FIG. And the reception apparatus 50 can select the report termination request in step S53, the call hold request in step S54, and the report history search in step S55 according to the operation of the supervisor in step S52.

  The accepting device 50 transmits a hold request signal to the reporting device 10 when the call hold request in step S54 is selected. In addition, when the report history search in step S55 is selected, the accepting device 50 can search the call history from the database 52 and refer to the past reports in step S56. Further, when the notification end request in step S53 is selected, the reception device 50 transmits an image data stop request signal and an audio data end request signal to the notification device 10 in step S57. The data is stored in the image storage unit 78 and the voice storage unit 79, and the notification process is terminated.

  Then, the accepting device 50 shifts the process to step S39 in FIG. 8 and requests the reporting device 10 for stored image data for which the reporting button 17 is pressed. The accumulated image data may include not only the notification button 17 but also the pending image data.

  Here, in step S51, for example, as illustrated in FIG. 10, the reception device 50 uses the latest temporal image data stored in the image storage unit 24 as the order of the request for the stored image data to the notification device 10. Request with priority. In response to this, the notification device 10 transmits the image data stored in the image storage unit 24 to the reception device 50 with priority from the latest image data in terms of time. Thereby, the reception device 50 can quickly grasp the event that occurred immediately before the operation of the notification button 17 in the door opening switch 16 by the reporter.

  In addition, when the reception device 50 determines that it is a normal time when there is no emergency notification in step S32 in FIG. 8 and the monitor performs a screen operation in step S33, the notification history in step S40. Either the search process or the normal image request process in step S41 can be performed. When the report history search in step S40 is selected, the accepting device 50 searches the call history from the database 52 in step S42, and can reproduce the stored image data and the stored voice data. Further, when the normal image request in step S41 is selected, the reception device 50 requests the designated notification device 10 to transmit the current image data.

  Further, when the reception apparatus 50 proceeds to the diagnosis process in step S34, the diagnosis content is determined in step S35, and if it is determined that there is an abnormality, the abnormality process is performed in step S43, and in step S44. The information is displayed on the display 62 so as to notify the monitor to that effect.

  As described above, according to the emergency notification system, the latest image data in time among the image data stored in the image storage unit 24 as the order of the request for the stored image data from the reception device 50 to the notification device 10. Since the request is given priority, the monitor can visually recognize the image data immediately before the notification button 17 is pressed even when the image data is being transferred. Therefore, even in the case of the network NT having a narrow communication band, the incident can be quickly grasped and early solution can be realized.

  In the emergency notification system, when there is an emergency notification from the other notification device 10 during transfer of image data from one notification device to the reception device 50, image data from one notification device to the reception device 50. Is temporarily interrupted, the notification process with the other reporting device 10 is performed, and after the reporting process with the other reporting device 10 and the transfer of the image data are completed, the image data from the one reporting device is completed. The transfer may be resumed.

  In the emergency notification system, when the hold operation is performed during the notification process in the reception device 50 and the pending image data is accumulated in the notification device 10, the notification button 17 is pressed after the notification process is completed. It is desirable to transfer the stored image data before the notification and the image data on hold. In this transfer, the notification device 10 transmits the image data before notification that the notification button 17 is pressed to the reception device 50, and then transmits the stored image data that is on hold or the stored image data that is on hold. The transmission order may be arbitrarily selectable such that image data before notification is transmitted after transmission.

  Further, in the case where a hold operation is performed during the notification process in the reception device 50, the emergency notification system does not store the set number of image data before the notification in the notification device 10 but during the hold. The accumulated time may be accumulated, and then the accumulated image data may be transferred. In this transfer, as described above, the notification device 10 transmits the image data before the notification to the reception device 50 and then transmits the stored image data during the hold or the storage image data during the hold. Later, the transmission order can be arbitrarily selected, such as transmitting image data before reporting.

  Furthermore, when the emergency notification system transfers image data from the notification device 10 to the reception device 50, for example, as shown in FIG. 11, the accumulated image data is thinned out at intervals of one sheet from the latest accumulated image data in terms of time. After the transmission to the end, the accumulated image data thinned out may be sequentially transmitted from the latest data in time. Note that the emergency call system may arbitrarily set the interval of image data to be transmitted instead of one. Furthermore, in this transfer, as described above, the notification device 10 transmits the image data before notification that the notification button 17 is pressed to the reception device 50, and then transmits the accumulated image data that is on hold. The transmission order can be arbitrarily selected, such as transmitting image data before notification after transmitting accumulated image data during suspension.

  In addition, in the emergency notification system, when the receiving device 50 is reporting to one of the reporting devices or transferring the stored image data, the other reporting device 10 reports both. In the completed state, for example, as shown in FIG. 12, the accumulated image data may be alternately transferred from both the reporting devices to the receiving device 50. In this case, the emergency call system can be combined with a method of transmitting accumulated image data at a predetermined interval as shown in FIG.

[Effect of the embodiment]
As described in detail above, according to the emergency notification system, the image data stored in the image storage unit 24 after the emergency detection by the door opening switch 16 is the latest in time. Since the image data is transmitted to the reception device 50 with priority, the image immediately before the notification when the notification button 17 is pressed can be viewed by the monitor in a short time even during the transfer of the image data. Therefore, even if the network NT has a narrow communication band, the operability can be improved, the incident can be quickly grasped, and an early solution can be realized.
