The communication terminal device 3 receives the information that the dehydrator DW1 is abnormal. In addition to the dehydrator DW1, the communication terminal device 3 may receive information that the monitoring target other than the dehydrator DW1 is abnormal.

(Processing flow of notification system S1)
A flow of processing of the notification system S1, that is, a notification method for notifying an abnormality in the monitoring target to the outside will be described based on FIGS. 3 to 6. FIG. 3 is a flowchart showing a processing flow of the notification system S1 shown in FIG. 4A to 4E are examples of screens displayed on the display unit 15 of the user terminal 1 shown in FIG. 5A to 5D are diagrams showing types of management screens displayed on the display unit 15 of the user terminal 1 shown in FIG. FIG. 6 is a diagram showing information in which a screen number is assigned to the abnormality content in the monitoring target shown in FIG.

  As shown in FIG. 3, an abnormality occurs in the dehydrator DW1 to be monitored (step S10). When abnormality occurs in the dehydrator DW1, the communication unit 25b of the communication terminal device 3 receives abnormality information that the abnormality occurs in the dehydrator DW1 and supplies the received abnormality information to the control unit 30b. The recording processing unit 310b records the abnormality information in the recording unit 20b.

  The communication processing unit 315b transmits the abnormality information recorded in the recording unit 20b to the communication unit 25a of the server 2 via the communication unit 25b. The communication unit 25a supplies the abnormality information to the control unit 30a. The recording processing unit 310a records the abnormality information in the recording unit 20a and instructs the authentication information acquisition unit 320a to acquire the authentication information.

  The authentication information acquisition unit 320a acquires from the recording unit 20a the authentication information recorded in advance in the recording unit 20a (step S11: authentication information acquisition step). The authentication information is information for accessing the management screen for managing the monitoring target, and is, for example, information including at least one of a one-time password and an ID and password preset by the user. The authentication information recorded in the recording unit 20a in advance is verification information used for verification and set for each user in advance.

  The ID and password may be set in advance on the server 2 side or may be pre-recorded in the recording unit 20a of the server 2 by the following process. Specifically, the ID and password are input by the user from the input unit 10 of the user terminal 1 and supplied to the control unit 30. The communication processing unit 315 transmits the ID and password to the communication unit 25a of the server 2 via the communication unit 25.

  When the user inputs the ID and password, the display processing unit 305 displays an ID and password input screen on the display unit 15, as illustrated in FIG. The communication unit 25a supplies the ID and password to the control unit 30a, and the recording processing unit 310a records the ID and password in the recording unit 20a.

  The authentication information acquisition unit 320a supplies the acquired authentication information to the message creation unit 335a. The message creation unit 335a creates a notification message including at least the authentication information acquired by the authentication information acquisition unit 320a in order to notify the abnormality of the monitoring target to the outside (step S12: message creation step). The message creating unit 335a supplies the created notification message to the communication processing unit 315a.

  The communication processing unit 315a transmits the notification message created by the message creating unit 335a to the communication unit 25 of the user terminal 1 via the communication unit 25a (step S13). At this time, the communication processing unit 315a may transmit the notification message to the communication units 25 of the plurality of user terminals 1. In this case, the authentication information included in the notification message may be different for each user terminal 1, and the authentication information supplied to all the user terminals 1 may be the same.

  The measurement unit 330a may measure the elapsed time from the moment when the communication processing unit 315a transmits the notification message to the communication unit 25 of the user terminal 1. In this case, the measuring unit 330a determines whether or not the elapsed time has passed the predetermined elapsed time. When the elapsed time has exceeded the predetermined elapsed time, even if the address information U1 described later included in the notification message is selected on the user terminal 1 side, the browsing-only screen described later may not be accessible. That is, it may not be possible to shift from step S15 to step S16 described later. This can improve security.

  The configuration in which the view-only screen described above cannot be accessed is the same in the following process. Specifically, regarding the configuration, in the processing of steps S33 to S35 of the notification system S2 described later, the processing of steps S53 to S55 of the notification system S3 described later, and the processing of steps S78 to S80 of the notification system S4 described later. Is also the same.

  The communication unit 25 receives the notification message from the communication unit 25a of the server 2 (step S14). The communication unit 25 supplies the received notification message to the control unit 30. The recording processing unit 310 records the notification message in the recording unit 20. At this time, when the user confirms the incoming call and activates the application for browsing the notification message, the display processing unit 305 displays the notification message recorded in the recording unit 20 on the display unit 15.

  An example of the notification message displayed on the display unit 15 is shown in FIGS. In (a) of FIG. 4, the notification message displays the date and time T1 when the abnormality occurred in the monitoring target, the content C1 of the abnormality in the monitoring target, and the address information U1. For example, the date and time T1 is the date and time information, the content of the abnormality C1 is the content indicating the occurrence of a failure related to the inverter of the main motor, and the address information U1 is the URL indicating the web page of the management screen. (Uniform Resource Locator).

  4B is different from FIG. 4A in that images CA1 to CA4 are displayed in the notification message instead of the address information U1. A URL is incorporated in the images CA1 to CA4 as address information, and when the user selects any one of the images CA1 to CA4, the web page of the management screen corresponding to the selected image is displayed.

  Each of the images CA1 to CA4 is a captured image of the management screen at the time when the abnormality occurs in the monitoring target. The image CA1 is an overall view of the equipment to be monitored, and the image CA2 is a view showing at least one of the installations to be monitored. The image CA3 is a trend graph showing a temporal change in the numerical value related to the monitoring target, and the image CA4 is a diagram showing a warning in each individual monitoring target of the equipment to be monitored.

  As shown in (b) of FIG. 4, by displaying the images CA1 to CA4 in the notification message as images of the management screen at the time when the abnormality occurs in the monitoring target, when the user browses the notification message, the user can It is possible to understand the details of the abnormality in the monitoring target. Therefore, the user can determine whether or not to log in to the management screen only by viewing the notification message. The images CA1 to CA4 may be thumbnail images. Further, as shown in FIG. 4C, the type CT1 of the processing plant where the abnormality in the monitoring target has occurred may be displayed in the notification message.

  After displaying the notification message recorded in the recording unit 20 on the display unit 15, the display processing unit 305 selects the address information U1 for the user to access the management screen in the case of (a) of FIG. 4, for example. Yes (step S15). When the user selects the address information U1, the input unit 10 supplies the control unit 30 with information that the user has selected the address information U1. The communication processing unit 315 transmits the authentication information included in the notification message recorded in the recording unit 20 to the communication unit 25a of the server 2 via the communication unit 25.

  The communication unit 25a supplies the authentication information transmitted from the communication unit 25 of the user terminal 1 to the control unit 30a. When the authentication information included in the notification message is supplied to the control unit 30a, the matching unit 340a matches the authentication information included in the notification message with the matching authentication information previously recorded in the recording unit 20a (step S16). ..

  The collating unit 340a permits access to the management screen in the user terminal 1 when the authentication information included in the notification message matches the collating authentication information previously recorded in the recording unit 20a. The user terminal 1 accesses the browsing-only screen as the management screen (step S17). When the user terminal 1 accesses the browse-only screen, the display unit 15 of the user terminal 1 indicates that the server 2 (the browse-only screen) is being accessed, as shown in (d) of FIG. 4, for example. The screen shown is displayed.

  In this way, the authentication information acquired by the authentication information acquisition unit 320a is information that allows access to the view-only screen. The viewing-only screen is a management screen in which viewing related to the status of the monitoring target is possible, but operation on the monitoring target is prohibited, and is a management screen when logging in with an ID to which only viewing authority is given, Or, it is a management screen created only for browsing without operating parts. As a result, since the user who has accessed the management screen is prohibited from operating the monitoring target, it is possible to prevent an erroneous operation by the user even if the user is in a panic when an emergency such as an abnormality in the monitoring target is required. The operation on the monitoring target is, for example, an operation of changing information such as numerical values related to the monitoring target.

  On the other hand, the collation unit 340a does not allow access to the management screen in the user terminal 1 when the authentication information included in the notification message does not match the collation authentication information previously recorded in the recording unit 20a. In this case, the user terminal 1 cannot access the management screen.

  5A to 5D show examples of the viewing-only screen displayed on the display unit 15 of the user terminal 1 when the user terminal 1 accesses the viewing-only screen. 5A is an overall view of the equipment to be monitored, and FIG. 5B is a diagram showing at least one of the equipment to be monitored. FIG. 5C is a trend graph showing temporal changes in the numerical values related to the monitoring target, and FIG. 5D is a diagram showing warnings in individual monitoring targets of the monitoring target equipment. ..

  In (a) of FIG. 5, a plurality of individual monitoring target DWAs are displayed on the viewing-only screen in the entire monitoring target equipment. When the viewing-only screen of FIG. 5A is displayed, the user can check the entire facility to be monitored. In FIG. 5B, the browsing-only screen displays, for example, at least one pump P1 / P2 and motor M1 of the dehydrator to be monitored out of the entire equipment to be monitored. Numerical values related to the pumps P1 and P2 and the motor M1 to be monitored may be displayed on the viewing-only screens of FIGS. 5A and 5B. When the view-only screen of FIG. 5B is displayed, the user can individually confirm at least one monitoring target of the entire monitoring target equipment.

  In FIG. 5C, a trend graph showing a temporal change in the numerical value related to the monitoring target is displayed on the view-only screen. When the view-only screen of FIG. 5C is displayed, the user can confirm the abnormality in the monitoring target by confirming the numerical value related to the monitoring target. In (d) of FIG. 5, a warning (alarm) for each individual monitoring target of the monitoring target equipment is displayed on the view-only screen. In the view-only screen of FIG. 5D, information indicating the date and time when the abnormality occurred in the monitoring target, the type of abnormality, and the state in which the abnormality is occurring or the state in which the abnormality has been recovered is displayed.

  As shown in FIG. 6, a screen number is assigned to the abnormality content of the management screen displayed on the display unit 15 of the user terminal 1. The information in which the screen number is assigned to the abnormality content in the monitoring target is recorded in the recording unit 20a of the server 2 in advance. In the case of a failure related to the inverter of the main motor, 4 is assigned as the screen number, 2 is assigned as the screen number if the bearing temperature is abnormally high, and the screen number is given in the case of overcurrent of the main power supply. Is assigned as.

  When the oil pressure is high, 3 is assigned as the screen number, when the flow rate is low, 1 is assigned as the screen number, and when the rotational speed is abnormal, 2 is assigned as the screen number. Assigned. The message creation unit 335a may include the screen number in the notification message as screen identification information for identifying and displaying a specific management screen from a plurality of management screens.

  Specifically, the message creating unit 335a includes the screen number as the screen identification information in the notification message when creating the notification message in step S12. Further, when the user selects the address information U1 in step S15, the communication processing unit 315 causes the communication unit of the server 2 to transmit the screen number included in the notification message recorded in the recording unit 20 via the communication unit 25. 25a.

  The communication unit 25a supplies the screen number transmitted from the communication unit 25 of the user terminal 1 to the control unit 30a. When the screen number included in the notification message is supplied to the control unit 30a, the user terminal 1 accesses the view-only screen, which is the management screen corresponding to the screen number included in the notification message.

  Specifically, when the screen number included in the notification message is 1, the management screen illustrated in FIG. 5A is displayed, and when the screen number included in the notification message is 2, the management screen illustrated in FIG. The management screen shown in (b) is displayed. When the screen number included in the notification message is 3, the management screen shown in (c) of FIG. 5 is displayed, and when the screen number included in the notification message is 4, shown in (d) of FIG. The management screen is displayed.

  In this way, by including the screen identification information for identifying and displaying the specific management screen in the notification message, the optimum management screen can be displayed when the user accesses the management screen. Therefore, the user can immediately check the optimum management screen and can quickly grasp the situation.

  The screen identification information included in the notification message may be, for example, a screen symbol other than the screen number, but is not particularly limited as long as a specific management screen can be identified from a plurality of management screens. Further, the processing relating to the screen identification information described here may be performed by the notification systems S2 to S4 described later.

  The measuring unit 330a measures the elapsed time from the moment when the user terminal 1 accesses the viewing-only screen. The measuring unit 330a determines whether the elapsed time has passed a predetermined time (step S18). When the elapsed time does not exceed the predetermined time (NO in step S18), the measuring unit 330a continues to measure the elapsed time. The predetermined time may be set to any time between 3 minutes and 5 minutes, for example.

  When the elapsed time has passed the predetermined time (YES in step S18), the viewing-only screen is switched to a screen for logging in to the regular management screen (step S19). Specifically, the communication processing unit 315a transmits, to the communication unit 25 of the user terminal 1 via the communication unit 25a, an instruction to switch the browse-only screen to a screen for logging in to the regular management screen. The regular management screen is a management screen that is different from the above-described viewing-only screen in that the viewing related to the status of the monitoring target can be viewed and the monitoring target can be operated.

  The communication unit 25 supplies the instruction to the control unit 30, and the display processing unit 305 switches the browse-only screen displayed on the display unit 15 to a screen for logging in to the regular management screen. That is, the authentication information acquired by the authentication information acquisition unit 320a is information that allows access to the management screen, which is the viewing-only screen, within the predetermined time. Thus, the user who receives the notification message can access the management screen only within the predetermined time. Therefore, the use of the management screen can be limited, and the security can be improved.

  It should be noted that instead of the process of step S18, a predetermined operation may be performed to switch to a screen for logging in to the regular management screen even if the predetermined time has not elapsed. Further, instead of the processing of steps S18 to S23, the user terminal 1 may access the regular management screen by performing the predetermined operation even if the predetermined time has not elapsed.

  The predetermined operation may be an operation of selecting a switching button displayed on the view-only screen, for example. The switch button is a button having a function of switching to a regular management screen when selected. As a result, the user can immediately access the management screen when the importance is very high and an emergency is required, and can quickly grasp the situation and take measures.

  When a screen for logging in to the authorized management screen is displayed on the display unit 15, an input field for inputting the ID and password is displayed on the display unit 15. At this time, the user inputs the ID and the password into the input field using the input unit 10 (step S20). When the ID and password are input in the input fields, the communication processing unit 315 transmits the ID and password input in the input fields to the communication unit 25a of the server 2 via the communication unit 25.

  The communication unit 25a supplies the ID and password transmitted from the communication unit 25 to the control unit 30a. After that, the collation unit 340a collates the ID and password as the authentication information with the ID and password as the collation authentication information previously recorded in the recording unit 20a, and the communication processing unit 315a uses the one-time password as the user's password. It transmits to the terminal 1 (step S21).

  Specifically, when the ID and password transmitted from the communication unit 25 match the ID and password previously recorded in the recording unit 20a, the matching unit 340a outputs the one-time password to the communication processing unit 315a. Instruct to send. The message creation unit 335a creates a notification message in which the one-time password is written, and supplies the notification message to the communication processing unit 315a.

  The message creating unit 335a may include the management number as the screen identification information in the notification message. The communication processing unit 315a transmits a notification message containing the one-time password to the communication unit 25 of the user terminal 1 via the communication unit 25a. The communication unit 25 supplies the notification message including the one-time password transmitted from the communication unit 25a to the control unit 30. At this time, the recording processing unit 310a records the one-time password in the recording unit 20a.

  When the notification message in which the one-time password is written is transmitted from the communication unit 25a to the control unit 30, the recording processing unit 310 records the notification message in which the one-time password is written in the recording unit 20. At this time, when the user confirms the incoming call and activates the application for browsing the notification message, the display processing unit 305 displays on the display unit 15 the notification message in which the one-time password recorded in the recording unit 20 is described. To do.

  The notification message includes a one-time password and an input field for inputting the one-time password. When the notification message is displayed on the display unit 15, the user inputs the one-time password into the input field using the input unit 10 (step S22). Here, in the notification message, only the one-time password is displayed, and a notification message in which an input field for inputting the one-time password is displayed may be separately transmitted from the communication unit 25a to the communication unit 25. .. When the one-time password is input in the input field, the communication processing unit 315 transmits the one-time password input in the input field to the communication unit 25a of the server 2 via the communication unit 25.

  The communication unit 25a supplies the one-time password transmitted from the communication unit 25 to the control unit 30a. After that, the collating unit 340a collates the one-time password as the authentication information with the one-time password as the collating authentication information previously recorded in the recording unit 20a (step S23).

  If the one-time password input by the user matches the one-time password previously recorded in the recording unit 20a, the collating unit 340a permits access to the regular management screen in the user terminal 1. The one-time password previously recorded in the recording unit 20a is the one-time password recorded in the recording unit 20a by the recording processing unit 310a when the notification message in which the one-time password is described is transmitted to the communication unit 25 of the user terminal 1. It is a time password. The user terminal 1 accesses the regular management screen (step S24). When the user terminal 1 accesses the regular management screen, the user terminal 1 may access the regular management screen which is the management screen corresponding to the screen number included in the notification message.

  Further, the following processing may be performed instead of the processing of steps S21 to S23. When the ID and password transmitted from the communication unit 25 match the ID and password as the verification authentication information recorded in the recording unit 20a in advance, the matching unit 340a accesses the regular management screen in the user terminal 1. Tolerate. After this, the process proceeds to step S24.

  The configuration in which the processing that replaces the processing in steps S21 to S23 described here is performed is the same in the following processing. Specifically, regarding the configuration, in the processes of steps S42 to S44 of the notification system S2 described later, the processes of steps S63 to S65 of the notification system S3 described later, and the processes of steps S86 to S88 of the notification system S4 described later. Is also the same.

  As described above, the server 2 acquires the authentication information for accessing the management screen that manages the monitoring target, and creates the notification message including at least the authentication information to notify the abnormality of the monitoring target to the outside. With this, since the notification message includes at least the authentication information, when the notification message is sent to the outside, the user who receives the notification message can immediately access the management screen without inputting the authentication information. .. Therefore, the user can immediately access the management screen and grasp the situation quickly when an emergency such as an abnormality in the monitoring target is required.

  Note that the message creation unit 335a may include terminal information for allowing access to the management screen in the notification message by identifying the user terminal 1 that is allowed to access the management screen. Specifically, the message creating unit 335a includes the terminal information in the notification message when creating the notification message in step S12.

  Further, when the user selects the address information U1 in step S15, the communication processing unit 315 causes the communication unit of the server 2 to include the terminal information included in the notification message recorded in the recording unit 20 via the communication unit 25. 25a.

  The communication unit 25a supplies the terminal information transmitted from the communication unit 25 of the user terminal 1 to the control unit 30a. When the terminal information included in the notification message is supplied to the control unit 30a, the identification unit 325a refers to the terminal information included in the notification message, and the user terminal 1 is allowed to access the browse-only screen. Identify whether it is a terminal.

  When the terminal information included in the notification message matches the verification terminal information recorded in the recording unit 20a in advance, the identification unit 325a permits access to the view-only screen in the user terminal 1. As a result, the user terminal 1 can access the browsing-only screen as the management screen.

  By including the terminal information in the notification message in this way, the message creating unit 335a can make only the designated user terminal 1 accessible to the management screen, for example. Therefore, the user terminal 1 that can access the management screen can be limited, and the security can be improved.

  Further, when the one-time password is transmitted to the user terminal 1 in step S21, the message creation unit 335a may include the terminal information in the notification message. In this case, in step S22, after the user inputs the one-time password in the input field, the communication processing unit 315 sends the terminal information included in the notification message recorded in the recording unit 20 via the communication unit 25. It is transmitted to the communication unit 25a of the server 2.

  The communication unit 25a supplies the terminal information transmitted from the communication unit 25 of the user terminal 1 to the control unit 30a. When the terminal information included in the notification message is supplied to the control unit 30a, the identification unit 325a refers to the terminal information included in the notification message, and the user terminal 1 is allowed to access the regular management screen. Identify whether it is a terminal.

  When the terminal information included in the notification message matches the verification terminal information recorded in the recording unit 20a in advance, the identification unit 325a permits access to the regular management screen in the user terminal 1. As a result, the user terminal 1 can access the regular management screen. Further, the processing regarding the terminal information described here may be performed by the notification systems S2 and S4 described later. Further, the processing regarding the terminal information in the communication unit 25a and the identification unit 325a is also performed in the notification system S3 described later.

  Note that the processing of the server 2 described in the processing flow of the notification system S1 may be performed by the communication terminal device 3 instead of the server 2. In this case, when the user terminal 1 and the communication terminal device 3 communicate with each other, the communication unit 25 of the user terminal 1 communicates with the communication unit 25b of the communication terminal device 3 via the communication unit 25a of the server 2 or the server 2 The communication terminal device 3 and the user terminal 1 directly communicate with each other without the device itself. In the notification systems S2 to S4 described later, the processing of the server 2 may be performed by the communication terminal device 3 instead of the server 2.

[Embodiment 2]
Another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by the same reference numerals, and the description thereof will not be repeated. FIG. 7 is a flowchart showing a processing flow of the notification system S2 according to the second embodiment of the present invention. The internal configuration of the notification system S2 may be the same as the internal configuration of the notification system S1, but the processing content of the notification system S2 is different from the processing content of the notification system S1.

(Processing flow of notification system S2)
A processing flow of the notification system S2, that is, a notification method for notifying an abnormality in the monitoring target to the outside will be described based on FIG. In FIG. 7, the process of step S30 is the same as the process of step S10 in the notification system S1. After the process of step S30, the authentication information acquisition unit 320a acquires the authentication information prerecorded in the recording unit 20a from the recording unit 20a (step S31: authentication information acquisition step). Unlike the case of step S11, the authentication information is not the ID and password preset by the user. The authentication information is, for example, a one-time password. The authentication information recorded in the recording unit 20a in advance is verification information used for verification.

  The authentication information acquisition unit 320a supplies the acquired authentication information to the message creation unit 335a, and the process of step S32 is performed. The processing of steps S32 to S35 is the same as the processing of steps S12 to S15 in the notification system S1. When the user selects the address information U1 in step S35, the input unit 10 supplies the control unit 30 with information that the user has selected the address information U1.

  The communication processing unit 315 transmits the terminal-side authentication information recorded in the recording unit 20 in advance and the authentication information acquired by the authentication information acquisition unit 320a to the communication unit 25a of the server 2 via the communication unit 25. The terminal-side authentication information is, for example, an ID and password preset by the user, and is information different from the authentication information acquired by the authentication information acquisition unit 320a. Further, the terminal side authentication information may be, for example, a cookie automatically recorded in the recording unit 20.

  The ID and password are previously recorded in the recording unit 20 of the user terminal 1 by the following process. Specifically, the ID and password are input by the user from the input unit 10 of the user terminal 1, and the input unit 10 supplies the ID and password to the control unit 30. The recording processing unit 310 records the ID and password in the recording unit 20.

  The communication processing unit 315 transmits the terminal-side authentication information recorded in the recording unit 20 in advance and the authentication information acquired by the authentication information acquisition unit 320a to the communication unit 25a of the server 2 via the communication unit 25. The communication unit 25a supplies the terminal-side authentication information and the authentication information transmitted from the communication unit 25 to the control unit 30a. The authentication information acquisition unit 320a acquires the terminal-side authentication information and the authentication information. In this way, the authentication information acquisition unit 320a selects the address information U1 described in the notification message created by the message creation unit 335a on the user terminal 1 to send the terminal-side authentication information from the user terminal 1. It is acquired (step S36).

  The authentication information acquisition unit 320a supplies the acquired terminal-side authentication information and authentication information to the matching unit 340a. The matching unit 340a matches the terminal-side authentication information acquired by the authentication information acquisition unit 320a and the authentication information included in the notification message with the matching authentication information pre-recorded in the recording unit 20a (step S37). The collating unit 340a permits access to the management screen in the user terminal 1 when the terminal-side authentication information and the authentication information respectively match the collating authentication information previously recorded in the recording unit 20a.

  In this way, the collation unit 340a collates the terminal-side authentication information acquired by the authentication information acquisition unit 320a with the verification authentication information recorded in advance in the recording unit 20a of the server 2 to manage in the user terminal 1. Allow access to the screen. Thereby, the terminal side authentication information different from the authentication information is acquired from the user terminal 1, and the terminal side authentication information is collated with the collation authentication information, whereby the management screen can be easily accessed. ..

  Therefore, the user can access the management screen without inputting the authentication information, and thus can access the management screen and grasp the situation quickly when an emergency such as an abnormality in the monitoring target is required. After step S37, the process of step S38 is performed. The processing of steps S38 to S45 is the same as the processing of steps S17 to S24 in the notification system S1.

[Embodiment 3]
Another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by the same reference numerals, and the description thereof will not be repeated. FIG. 8 is a flowchart showing a processing flow of the notification system S3 according to the third embodiment of the present invention. The internal configuration of the notification system S3 may be the same as the internal configuration of the notification systems S1 and S2, but the processing content of the notification system S3 is different from the processing content of the notification systems S1 and S2.

(Processing flow of notification system S3)
A processing flow of the notification system S3, that is, a notification method for notifying an abnormality in the monitoring target to the outside will be described with reference to FIG. In FIG. 8, the processes of steps S50 to S55 are the same as steps S30 to S35 in the notification system S2. When the user selects the address information U1 in step S55, the input unit 10 supplies the control unit 30 with information that the user has selected the address information U1.

  When the control unit 30 receives the information that the user has selected the address information U1 from the input unit 10, the control unit 30 activates the application preinstalled in the user terminal 1 (step S56). When the application is activated, the communication processing unit 315 transmits the terminal-side authentication information and the terminal information prerecorded in the recording unit 20 to the communication unit 25a of the server 2 via the communication unit 25. The terminal authentication information and the terminal information are the same as the terminal-side authentication information and the terminal information in the notification system S2, respectively. The communication processing unit 315 also transmits the authentication information included in the notification message to the communication unit 25a of the server 2 via the communication unit 25.

  The application is an application used to access a management screen that manages monitoring targets. Further, before step S50, the terminal information of the user terminal 1 is recorded in the recording unit 20a of the server 2 in advance as collation terminal information using the application. After the processing of step S56, the processing of step S57 is performed. The processing of steps S57 to S66 is the same as the processing of steps S36 to S45 in the notification system S2.

[Embodiment 4]
Another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by the same reference numerals, and the description thereof will not be repeated. FIG. 9 is a flowchart showing a processing flow of the notification system S4 according to the fourth embodiment of the present invention. The internal configuration of the notification system S4 may be the same as the internal configuration of the notification systems S1 to S3, but the processing content of the notification system S4 is different from the processing content of the notification systems S1 to S3.

(Processing flow of notification system S4)
A processing flow of the notification system S4, that is, a notification method for notifying an abnormality in the monitoring target to the outside will be described based on FIG. In FIG. 9, the process of step S70 is the same as the process of step S10 in the notification system S1. In step S70, after the recording processing unit 310a records the abnormality information in the recording unit 20a, the recording processing unit 310a instructs the message creating unit 335a to create the preliminary notification message.

  The message creating unit 335a creates a preliminary notification message for sending the notification message including at least the authentication information to the outside and sends the preliminary notification message to the outside (step S71). Examples of the preliminary notification message include an HTML mail, a message by a LINE (registered trademark) application, and the like. The message creation unit 335a supplies the created preliminary notification message to the communication processing unit 315a. The communication processing unit 315a transmits the preliminary notification message created by the message creating unit 335a to the communication unit 25 of the user terminal 1 via the communication unit 25a (step S72). That is, the message creation unit 335a transmits the preliminary notification message to the communication unit 25 of the user terminal 1 via the communication processing unit 315a and the communication unit 25a.

  The measurement unit 330a may measure the elapsed time from the moment when the communication processing unit 315a transmits the preliminary notification message to the communication unit 25 of the user terminal 1. In this case, the measuring unit 330a determines whether or not the elapsed time has passed the predetermined elapsed time. When the elapsed time has exceeded the predetermined elapsed time, the authentication information may not be acquired even if the address information U1 included in the preliminary notification message is selected on the user terminal 1 side. That is, it may not be possible to move from step S74 to step S75 described later. This can improve security.

  The communication unit 25 receives the preliminary notification message from the communication unit 25a of the server 2 (step S73). The communication unit 25 supplies the received preliminary notification message to the control unit 30. The recording processing unit 310 records the preliminary notification message in the recording unit 20. At this time, when the user confirms the incoming call and activates the application for browsing the preliminary notification message, the display processing unit 305 displays the preliminary notification message recorded in the recording unit 20 on the display unit 15.

  The display processing unit 305 displays the preliminary notification message recorded in the recording unit 20 on the display unit 15, and then the process of step S74 is performed. The process of step S74 is the same as the process of step S15 in the notification system S1. When the user selects the address information U1 in step S74, the input unit 10 supplies the control unit 30 with information that the user has selected the address information U1. The communication processing unit 315 transmits the mail address of the user terminal 1 recorded in the recording unit 20 to the communication unit 25a of the server 2 via the communication unit 25.

  The communication unit 25a supplies the mail address transmitted from the communication unit 25 of the user terminal 1 to the control unit 30a. When the mail address is supplied to the control unit 30a, the matching unit 340a matches the mail address with the matching mail address previously recorded in the recording unit 20a (step S75).

  The matching unit 340a instructs the authentication information acquisition unit 320a to acquire the authentication information when the mail address matches the matching mail address previously recorded in the recording unit 20a. It is to be noted that here, although it has been described that the collation unit 340a performs the process of collating the mail address, the process of collating may be performed by the information other than the mail address. Then, the process of step S76 is performed. The processing of steps S76 to S89 is the same as the processing of steps S11 to S24 in the notification system S1.

  Therefore, when the address information U1 described in the preliminary notification message for accessing the management screen is selected on the user terminal 1, the communication processing unit 315a transmits a notification message including at least authentication information to the outside. As described above, by creating the preliminary notification message for transmitting the notification message to the outside, the user can access the management screen through the two-step processing of the preliminary notification message and the notification message. Therefore, security can be improved.
