[2 Monitoring system]
Subsequently, the configuration of the monitoring system 1 will be described, and a monitoring method using the monitoring system 1 will be described.

  The monitoring system 1 includes a water monitoring device 10, a host device 20, a terminal 30, and the like. The water monitoring device 10 is installed in the house 50, the host device 20 is installed in a place away from the house 50 (for example, the location of the service provider, the location of the house manufacturer, etc.), and the terminal 30 is a portable portable terminal. . The water monitoring device 10 and the host device 20 can communicate with each other via an electric communication line (for example, the Internet, a dedicated line, a telephone line, etc.). The host device 20 and the terminal 30 can communicate with each other via an electric communication line (for example, the Internet, a dedicated line, a mobile phone line). The communication network between the water monitoring device 10 and the host device 20 is the same as or different from the communication network between the host device 20 and the terminal 30.

  The energy display (10) described in Japanese Patent Application Laid-Open No. 2012-248040 has functions equivalent to the water monitoring device 10, the service providing server (30) has functions equivalent to the host device 20, and the information terminal (20) has terminals. A function equivalent to 30 can be incorporated. Therefore, the matter described in JP2012-248040A is regarded as the matter described in the specification of the present application. When functions equivalent to the water monitoring device 10, the host device 20, and the terminal 30 are incorporated in the energy display (10), the service providing server (30), and the information terminal (20) described in JP2012-248040A, The water usage detection part (16c) described in JP2012-248040A can be used also as the water meter 51.

  Hereinafter, the water supply monitoring device 10, the host device 20, and the terminal 30 will be described in detail.

[2.1 Water monitoring equipment]
The water monitoring apparatus 10 includes a CPU, a storage unit (RAM, ROM, nonvolatile memory, hard disk drive, etc.), a communication unit, an input / output interface, a display unit (for example, a liquid crystal display or an EL display), and an operation unit (for example, a push button, A small computer having a touch panel, a switch, and the like. The storage unit built in the water monitoring apparatus 10 stores a program that can be read by the water monitoring apparatus 10, and the water monitoring apparatus 10 executes various processes according to the program. The process which the water supply monitoring apparatus 10 performs in each step based on the program is demonstrated.

[2.1.1 Usage monitoring step]
The water monitoring apparatus 10 acquires the amount of used water (total amount used) supplied to the house 50 and monitors the amount of use. That is, the water monitoring apparatus 10 inputs the electrical signal output by the water meter 51. Moreover, the water monitoring apparatus 10 inputs the electric signal output by the water meters 56, 57, and 58.

[2.1.2 Steps for calculating and storing usage per unit period]
The water monitoring device 10 stores the usage amount (total usage amount) represented by the electric signal input from the water meter 51 in the storage unit in association with the input time every predetermined unit period (for example, 30 minutes). Do. Furthermore, the water supply monitoring device 10 subtracts the usage amount stored once before from the usage amount stored at that time, and stores the difference obtained by the subtraction in association with the input time. The obtained difference is the usage amount used during the period from the time when the usage amount was stored last time to the time when the usage amount was stored this time. Hereinafter, the obtained difference is referred to as a unit period usage amount.

  Since the usage amount, the unit period usage amount and the input time are accumulated in the storage unit of the water monitoring apparatus 10 every unit period, a data string (database) in which the usage amount, the unit period usage amount and the input time are associated with each other is created. It is generated in the storage unit of the water monitoring device 10. An example of the data string is shown in FIG.

  In addition, the usage-amount of the clean water supplied to the house 50 is good also as what uses the water meter 56,57,58. That is, the water monitoring apparatus 10 receives the electrical signals output from the water meters 56, 57, and 58, obtains the sum of the amounts used by the electrical signals, and associates the sum with the input time of the electrical signals. Is stored in the storage unit. And if the usage amount memorize | stored once before from the usage amount which the water supply monitoring apparatus 10 memorize | stored at that time, the difference will become a unit period usage amount, and the unit period usage amount will be memorize | stored by the water supply monitoring apparatus 10 .

[2.1.3 Usage amount transmission step]
During the step of calculating and storing the unit period usage amount as described above, the water supply monitoring device 10 transmits the unit period usage amount calculated as described above to the host device 20 together with the input time. The water supply monitoring device 10 performs such transmission every time the unit period usage amount is calculated. That is, the water supply monitoring apparatus 10 performs such transmission every transmission cycle equal to the unit period.

[2.2 Host device 20]
The host device 20 is a server device having a CPU, a storage unit (RAM, ROM, nonvolatile memory, hard disk drive, etc.), a communication unit, an input / output interface, and the like. The storage unit built in the host device 20 stores a program that can be read by the host device 20, and the host device 20 executes various processes according to the program. Processing that the host device 20 executes in each step based on the program will be described.

[2.2.1 Reception step]
Whenever the water monitoring device 10 transmits the unit period usage amount and the input time, the host device 20 receives the unit period usage amount and the input time transmitted by the water monitoring device 10, and receives the received unit period usage amount and input. The times are associated with each other and stored in the storage unit. Since the storage of the unit period usage amount and the input time is performed every time the water supply monitoring device 10 transmits the unit period usage amount and the input time, the data string of the unit period usage amount and the input time is stored in the host device 20. To be generated.

[2.2.2 Comparison step]
The host device 20 determines whether or not the unit period usage amount is equal to or greater than the threshold value by comparing the unit period usage amount received as described above with a predetermined threshold value (predetermined amount). Store in association with the input time. The threshold here is a value exceeding zero. For example, the threshold is preferably equal to a predetermined amount (for example, 3 liters) that flows to the flush toilet 54 at a time.

  The host device 20 performs the comparison as described above every time it receives the unit period usage amount as described above. Therefore, the comparison result is accumulated in the storage unit of the host device 20 in addition to the unit period usage amount and the input time, and a data string (database) in which the unit period usage amount and the input time are associated with the comparison result is generated in the storage unit. The An example of the data string is shown in FIG. Here, when the comparison result is “YES” in FIG. 3, the unit period usage is equal to or greater than the threshold, and when the comparison result is “NO”, the unit period usage is less than the threshold.

[2.2.3 Determination step]
The host device 20 determines whether or not all the comparison results accumulated in the storage unit during the most recent predetermined period (hereinafter referred to as a determination cycle) are “NO”. That is, the host device 20 compares all the unit period usage amounts accumulated in the storage unit during the most recent determination cycle with the above-described threshold value, and determines whether or not all the unit period usage amounts are less than the threshold value. judge.

  The host device 20 makes such a determination every determination cycle. Here, the determination cycle is longer than the unit period, and the determination cycle is an integral multiple of one day or the integral multiple of the determination cycle is one day. For example, the determination cycle is half a day (12 hours), 1 day (24 hours), 2 days (48 hours), or 3 days (72 hours).

  This determination step can be disabled and enabled. When the determination step is invalidated, the above determination is not performed by the host device 20. When the determination step is validated, the host device 20 performs the above determination every determination cycle. Whether the determination step is valid or invalid, the host device 20 performs the reception step and the comparison step described above.

The period from the start of the determination step (when the determination step becomes valid) to the first determination (hereinafter referred to as the initial period) can be set shorter than the determination cycle. If the initial period is shorter than the determination cycle, the data string (mainly the unit period use amount or comparison result) before the start of the determination step is used for determination retroactively (see FIG. 4).
Further, the value of the determination cycle can be changed, and the change is performed using the terminal 30.

[2.2.4 Alarm transmission step]
When the comparison results accumulated in the storage unit during the most recent determination cycle are all “NO” (that is, all unit period usages accumulated in the storage unit during the most recent determination cycle are less than the threshold value) The host device 20 transmits an e-mail addressed to the registered e-mail address. The e-mail transmission protocol is, for example, SMTP (Simple Mail Transfer Protocol). The title or text of the e-mail represents an alarm. For example, the title or text of the e-mail describes that there is a possibility that something abnormal has occurred in the resident of the house 50. The title of the e-mail can be changed, and the change is performed using the terminal 30.

  When even one comparison result accumulated in the storage unit during the most recent determination cycle is “YES” (that is, even if the unit period usage amount accumulated in the storage unit during the most recent determination cycle is one threshold value In this case, the host device 20 does not transmit an e-mail.

  The alarm message transmission means may not be an email based on SMTP. Further, the host device 20 may directly transmit the alarm message to the terminal 30 or may transmit it to the terminal 30 via various servers.

  This alarm transmission step can be disabled and enabled. If the determination step is invalid, the alarm transmission step is also invalidated. If the determination step is valid, the alarm transmission step is also valid.

[2.3 Terminal]
The terminal 30 includes a CPU, a storage unit (RAM, ROM, nonvolatile semiconductor memory, etc.), a communication unit, an input / output interface, a display unit (for example, a liquid crystal display or an EL display), and an operation unit (for example, a push button, a touch panel, a switch). Etc. are portable computers. More specifically, the terminal 30 is a so-called smartphone (multifunctional mobile phone) or tablet formed in a plate shape. The terminal 30 is equipped with an operating system (hereinafter referred to as OS) for operating and managing the terminal 30. This OS (for example, iOS, ANDROID, WINDOWS, Linux (all are registered trademarks)) is stored in the storage unit, and this OS is executed by the CPU or the like of the terminal 30, and the OS manages, operates, Driven. An application program (hereinafter referred to as an application) for an e-mail client is installed in the OS, and the application is stored in the storage unit of the terminal 30. In addition, a remote operation application (for example, a browser application or a dedicated application) for communicating with the host device 20 is installed in the OS, and the remote operation application is stored in the storage unit of the terminal 30. Hereinafter, the process which the terminal 30 performs in each step based on these applications is demonstrated.

[2.3.1 Mail reception step (e-mail client application)]
When the application for the e-mail client of the terminal 30 is activated, the terminal 30 receives an e-mail from the e-mail server by the application. Therefore, when an alarm e-mail is transmitted by the host device 20 as described above, the e-mail is received by the terminal 30 by the e-mail client application, and the e-mail title and body are displayed by the e-mail client application. 30 display parts. The e-mail reception protocol is POP (Post Office Protocol), APOP (Authenticated Post Office Protocol), or IMAP (Internet Message Access Protocol).

  If the transmission protocol of the alarm message is not SMTP, a message receiving application is installed in the terminal 30, and the alarm message transmitted by the host device 20 is received by the terminal 30 by the application, and the alarm message is transmitted. Is displayed on the display unit of the terminal 30 by the application.

[2.3.2 Setting and browsing steps (remote control application)]
When the remote operation application of the terminal 30 is activated, the above-described determination step and alarm transmission step can be activated and stopped using the remote operation application.

  A GUI (Graphical User Interface) of the remote operation application will be described with reference to FIG. FIG. 5 shows a screen displayed on the display unit of the terminal 30 by the remote operation application.

  As shown in FIG. 5, a status display unit 91, an input box 92, pull-down menus 93 and 94, a start icon 95, a stop icon 96, a status display unit 97, and a history display unit 98 are arranged on the display screen of the remote operation application. Has been.

  The status display unit 91 displays an input time associated with the most recent unit period usage amount exceeding zero in the data string generated in the storage unit of the host device 20. Here, when the terminal 30 requests the latest usage time from the host device 20 by the remote operation application, the host device 20 is associated with the most recent unit period usage exceeding zero from the data string in the storage unit. The input time is searched, and the searched input time is transmitted to the terminal 30. The terminal 30 displays the received input time on the status display unit 91.

  The status display unit 97 displays the states of the determination step and the alarm transmission step. If the determination step and the alarm transmission step are valid, that fact (specifically, “watching is in progress” as shown in FIG. 5) is displayed on the status display section. If the determination step and the alarm transmission step are invalid, that fact (specifically, “watching is stopped”) is displayed on the status display section.

  The history display unit 98 displays input times associated with some unit period usages that have recently exceeded zero in the data string generated in the storage unit of the host device 20.

  In the input box 92, a character string can be input. The character string input in the input box 92 is used as the title of the e-mail or alarm message transmitted in the alarm transmission step described above.

  The pull-down menu 93 is for setting the value of the determination cycle in the above-described determination step. If a pull-down menu 93 is clicked or tapped, one of a plurality of options (determination cycle value candidates) is selected, and the selected option is set as a determination cycle value.

  The pull-down menu 94 is for setting the determination time (particularly, the first determination time) in the above-described determination step. When the option selected from the pull-down menu 93 is half a day (12 hours), the option (candidate for judgment time) that can be selected from the pull-down menu 94 is one hour or every minute of the 12-hour time method. It is time of. When the option selected in the pull-down menu 93 is an integer number of days, the options (candidates for determination time) that can be selected in the pull-down menu 94 are every hour or every minute of the 24-hour clock system. is there. If a pull-down menu 94 is clicked or tapped, one of a plurality of options (determination time candidates) is selected, and the selected option is set as the determination time.

  The start icon 95 is for enabling the above-described determination step and alarm transmission step. The stop icon 96 is for invalidating the above-described determination step and alarm transmission step.

  The user operates the operation unit of the terminal 30 to input a character string in the input box 92, selects one option from the pull-down menu 93, and selects one option from the pull-down menu 94. Then, the user operates the operation unit of the terminal 30 and clicks or taps the start icon 95. Then, the terminal 30 inputs and acquires the character string in the input box 92, the options in the pull-down menu 93 and the options in the pull-down menu 94, and transmits the input contents to the host device 20.

  When the host device 20 receives the character string in the input box 92 from the terminal 30, the character string is stored in the storage unit as the title of the e-mail or alarm message. Therefore, when the host device 20 generates an e-mail or an alarm message in the above-described alarm transmission step, the title of the e-mail or the alarm message is changed to the character string.

  Further, when the host device 20 receives an option in the pull-down menu 93 from the terminal 30, the option is stored in the storage unit as the value of the determination cycle, and the above-described determination step and alarm transmission step are validated. The alarm transmission step is started.

  When the host device 20 receives an option in the pull-down menu 94 from the terminal 30, the option is stored in the storage unit as a determination time. When the time elapses from the start of the determination step and the alarm transmission step and reaches the determination time, the host device 20 performs the first determination of the above-described determination step, and then performs the determination every time the determination cycle elapses ( [See 2.2.3 Judgment step]). Therefore, if the initial period from the start of the determination step to the determination time is shorter than the determination cycle, the data string (mainly the unit period usage amount or comparison result) before the start of the determination step is used retrospectively for determination. (See FIG. 4).

[3 Effects and effectiveness of the monitoring system]
According to the embodiment of the present invention, the following effects, effective points, and technical significance are recognized.

(1) Even if the user is outside the house 50, the presence / absence or safety of the resident of the house 50 can be confirmed. In other words, when there is no resident or the person cannot move, the water is not used in the house 50 for a long time. In such a case, as a result of the determination in the above-described determination step (see [2.2.3 Determination Step]), an alarm e-mail or an alarm message is transmitted by the host device 20 ([2.2.4 Alarm transmission step]), the owner of the terminal 30 can grasp the absence or abnormality of the resident of the house 50.

(2) The house 50 has a water supply facility (for example, a water heater 55) that automatically uses clean water. Therefore, if the presence / absence or safety of the resident of the house 50 is determined by determining whether the water is used in the house 50, the determination result is not correct. Therefore, in this embodiment, the presence / absence or safety of the resident of the house 50 is determined by determining whether or not the usage amount during the unit period is equal to or greater than the threshold by using a threshold value exceeding zero ( [Refer to [2.2.2 Comparison step] and [2.2.3 Determination step]). Therefore, even if a water supply facility that automatically uses clean water is provided in the house 50, the accuracy of determination of the presence / absence or safety of the resident of the house 50 is improved. In particular, if the threshold is equal to a predetermined amount that flows to the flush toilet 54 at a time, the presence / absence or safety of the resident can be determined based on whether the resident has used the flush toilet 54 or not.

(3) If the determination step becomes valid, determination is performed every determination cycle, and the determination step is continued (see [2.2.3 Determination step]). Therefore, the presence / absence or safety of the resident of the house 50 can be continuously monitored.

(4) Even when the determination step is invalid, the unit period usage amount and the input time are accumulated in the storage unit of the host device 20. Therefore, when the determination step is enabled and started, the unit period usage amount and the input time accumulated in the storage unit before the start time can be used retrospectively. Therefore, even if the initial period from the start time to the first determination time is shorter than the determination cycle, the presence / absence or safety of the resident can be determined at the first determination time. In addition, by using the terminal 30 to set the first determination time, the starting point of the determination cycle can be set to the first determination time. When the user of the terminal 30 is convenient, an alarm e-mail or The message will be sent.

(5) If the water meter 51 is used, it is not necessary to individually measure the amount of water used in the water facilities 53, 54, 55.

(6) By using the existing water meter 51, the monitoring system 1 can be constructed, and the flush toilet 54 need not be refurbished.

(7) Since data is collected in the host device 20 (see [2.2.1 Receiving Step]) and the determination is made based on the collected data ([2.2.2 Comparison Step] and [ 2.2.3 Judgment step]), it is not necessary to use a computer with a high processing speed for the water monitoring device 10. Therefore, the power consumption in the house 50 can be suppressed, and the running cost is low for the resident of the house 50.
