Description

  The present invention mainly relates to an apparatus provided with a monitoring function for the safety of residents in a centralized metering device for water consumption in an apartment house.

  The water meter of each house is mainly installed outside the dwelling unit (mainly a common part in the case of collective housing), and meter reading is performed once every two months. When metering the amount of water used by each dwelling unit, individual meter reading is performed by metering the display board of a water meter installed in each unit.

  Conventionally, in order to facilitate this meter reading work, a centralized meter reading method has been used in which the electrical signal of the amount used from the water meter of each dwelling unit is connected to a meter reading device at one point, and the amount of usage for multiple units is metered at one location. It has been broken.

  It is mainly determined by the water meter owner to select individual meter reading or centralized meter reading. Normally, a water meter owner is a water station having jurisdiction, but in the case of an apartment house, the water meter ownership of each dwelling unit may be transferred to an apartment house owner or an administrator.

  Water meter owners are obliged to replace the meter every 8 years or re-certify under the Measurement Law, but most owners replace the meter, which is cheaper than the verification.

  As a conventional monitoring device for confirming the safety of residents and preventing lonely death, human sensors, door opening / closing sensors, etc. are installed in the dwelling units in combination with monitoring of various usages such as water, electricity, gas, etc. Furthermore, many have been proposed in which a monitoring device main body is provided in a dwelling unit to confirm the safety of residents.

  The life abnormality monitoring system shown in Japanese Patent No. 3160082 (Patent Document 1) installs various sensors and a water meter in a detached house, and uses the telegram communication of the water meter to the water department and welfare section of public organizations. In the monitoring system and monitoring method disclosed in Japanese Patent Application Laid-Open No. 2015-26225 (Patent Document 2), a water monitoring communication device is installed in the living room, and the water usage is sent to the host. A technology that reports safety when the amount of water used on the host device side is less than a predetermined threshold, or a human sensor or door sensor installed in the room of a single person shown in Japanese Patent No. 4984274 (Patent Document 3). Some are low-cost types to monitor.

  In recent years, lonely death due to heat stroke or sudden illnesses such as elderly living alone has become a social problem, but the safety confirmation method without the monitoring device and monitoring system is the relative of the target resident, Local welfare departments, municipal welfare officers, apartment managers, caregivers at neighboring welfare facilities, or local community turnovers composed of local residents, etc.

  Depending on the area, this call-to-speech movement may be performed by a water meter meter.

  Introducing safety monitoring by devices and systems can be a great help for this voice call exercise.

Patent No. 3160082 JP 2015-26225 A Japanese Patent No. 4984274

Problems to be solved by the invention

  However, although safety monitoring devices tend to be installed in new houses, nursing homes, and elderly housing complexes, there is a problem that they are difficult to introduce in existing housing complexes such as aged housing complexes and apartments. It was.

  In the artificial voice call movement, the person in charge periodically visits each home, so it is not possible to visit frequently, and even in the event of an emergency, the timing depends on the visit timing. As mentioned above, there is a case where a water meter reading is also performed, but since the frequency is once every two months, the cycle is too long to confirm safety.

  Introducing safety monitoring with devices and systems will help with this voice exercise. However, the reason why it is difficult to introduce a safety confirmation system into an existing apartment house is that a monitoring resident installs equipment, sensors, communication environment, etc. in his / her residence in a surveillance system installed in a living room. If you refuse to do so, you can't monitor because you can't install the necessary equipment.

  In terms of cost, a big problem arises as to who will bear the burden. There is no problem with the person who is being monitored or their close relatives who voluntarily introduce devices or systems, but most of the solitary persons who die alone are elderly and have no financial leeway. There are many cases that have problems such as lack of people.

  Residential owners (owners of rental housing), managers, and neighboring residents do not want resident individuals such as singles and senior citizens to die lonely. This is not only from the viewpoint of human dignity, but also from the viewpoint of protecting property and protecting the surrounding environment.

  For this reason, it is desirable for the local government, managers and owners of apartment houses to bear the costs.

  However, when installing the equipment, when installing the equipment in the living room of the monitored person, first explain the circumstances to the resident, obtain permission from the resident, and perform the construction in the presence of the resident, You must take the procedure.

  In this case, as described above, the resident may be refused. In the explanation, it is explained to the person to be monitored that monitoring is performed.

  The above problems have become a major factor that does not lead to widespread use of safety monitoring by devices and systems.

Means for solving the problem

The present invention has been made from the above circumstances, and the object of the present invention is to

At the time of the safety information update of each dwelling unit, via the communication means, a reporting means for sending an email describing the safety information to a preset reporting destination;
This is achieved by including the parameter setting means that can set the validity / invalidity of the safety monitoring function of each dwelling unit and the destination mail address.

In addition, the object of the present invention is that the parameter setting means can set in advance information on the name, gender, age, contact information of the person to be monitored, and remarks information on the person to be monitored. It is achieved more effectively by providing a function for describing the information of the person.

Further, the above object of the present invention can further specify the absence state of the absence transition means and the setting of the parameter setting means by an external information processing terminal having a web browser function via the communication means. By providing the remote control means, it is achieved more effectively.

  In addition, the above object of the present invention is based on the data that is continuously stored by the storage means and divided into days, and the average water usage for a plurality of days in a predetermined detection time zone is in use. Yes, it is more effective by further comprising a short-time unused detection means that determines that it is abnormal when the total amount of water usage in the current detection time zone is unused, and updates the safety information of the dwelling unit. Is achieved.

Effect of the invention

  According to the present invention, each dwelling unit's dwelling unit is configured by the configuration of the existing water amount detection facility of the apartment house, the centralized water amount metering device having a safety monitoring function, and the external information processing terminal such as a PC, a tablet, and a smartphone. A safety monitoring device can be easily introduced at low cost without performing construction work in the residence, which is a great help for human safety confirmation such as voice call exercise.

  Furthermore, as the water usage status of the person to be monitored becomes more detailed as the measurement is performed, the determination accuracy increases, and the safety determination can be performed in a shorter time.

  Moreover, since it also has a function as a centralized meter-reading device, the introduction merit by simplification of water consumption meter-reading is also high for the owners and managers of apartment houses.

  The measuring means according to the present invention is that the centralized meter reading device receives an electrical signal from a water meter and measures the water usage of each dwelling unit.

  The centralized water meter reading device having a safety monitoring function according to the present invention includes a microcomputer, RAM, ROM, real time clock (RTC), I / O, communication I / F, nonvolatile memory, display, operation I / F, etc. It is the measurement recording device comprised by these. Process data such as measurement data, determination results, and parameters are mainly stored and stored in a nonvolatile memory.

  Hereinafter, a centralized meter reading device having a safety monitoring function is referred to as a central meter reading device.

  This centralized meter-reading device is installed outdoors, and the outdoor refers mainly to a section of the apartment house.

  In addition, it is also possible to connect the water meter of each dwelling unit and install a centralized meter reading device in a common facility or the like in the town, etc.

It is said that the average amount of water used by one person per day is about 200 to 300 liters.
Water meters to be used include those with pulse output, analog output, and telegram output, and the minimum measurement amount for signal output is less than 1 liter, 1 liter, 10 liter, 100 liter, 1000 liter, and the like.

  In view of the above-mentioned average daily water usage amount, the minimum measurement amount of the water meter used in the present invention is preferably one that outputs an electric signal of 10 liters or less, preferably 1 liter or less.

  A typical centralized meter reading device reads the electrical signal from the water meter with the above signal output, performs pulse signal integration counting, analog signal scale conversion, message analysis, etc., and displays water usage such as daily and monthly reports. Or print.

  The method of confirming the safety only with the amount of water used is that the subject does not use the water in a normal time, such as when water that should normally be used is not used or when the water continues to flow. Even if it is used, it is determined by determining that it is abnormal.

  The standard time for determining the usage is called unit time. The unit time is the minimum time interval for measuring the amount of use. The shorter the time, the more detailed the use status can be grasped, but it is necessary to use a water meter that measures the amount of water in more detail.

  Moreover, in the water meter with a large minimum measurement unit, since it takes time until the minimum measurement value appears, it is necessary to increase the unit time.

  The unit time of each dwelling unit is made variable. Assuming that the average daily usage is about 10 liters per hour, if the minimum metering amount of the water meter is 1 liter, it is about 30 minutes to 1 hour. About 2 hours, 100 liters may be about 12 to 24 hours, 1000 liters about 4 to 5 days, etc.

  As described above, the unit time varies depending on the minimum measurement unit of the water meter.

  Since the safety determination is performed based on the unit time described above, the longer the unit time, the more time is required for the safety determination. For this reason, it is desirable to use a water meter with a minimum measurement amount of 10 liters or less, preferably 1 liter or less, and set the unit time to about 1 hour.

  The measured usage amount per unit time is continuously stored by the storage means every time the unit time elapses with reference to the built-in timer or RTC of the microcomputer. For example, if the unit time is 1 hour, the usage amount for each hour is sequentially arranged in the memory area.

  The memory area for storing measurement data stores measurement data such as daily report usage, monthly report usage, and annual usage of each dwelling unit in addition to the usage per unit time.

  The number of data stored per unit time by the above-mentioned storage means depends on the number of target units and the storage capacity of the centralized meter reading device, but if the storage capacity is 128 kilobytes, the number of units is 40, and the usage data is expressed in binary 2 bytes. Unit time data of 1638 times per dwelling unit can be stored. Assuming that the unit time is 1 hour, data for about 2 months can be secured.

  Safety information includes the name (room number, etc.) of the dwelling unit that is the target of the unused determination means, the release determination means, the short-time unused detection means, and the absence change means, the time when it is generated / released, This is information such as cancellation details.

  When this safety information is updated, a report is sent by e-mail to the report destination mail address set by the parameter setting means.

  If this safety information is continuously stored in the memory area of the storage means so that it can be viewed, information as a report history can be provided.

  That the amount of water supply is unused means that it is below the unused threshold. “Unused” means that the amount used is normally zero, but it is not used in consideration of the case where a small amount of detected amount accumulates due to instrumental differences in the water meter or the environment, and the amount used appears. It is corrected with a threshold value.

  The amount of water used is a state where it is not in an unused state.

  The unused determination is determined to be abnormal when the usage amount per unit time is unused for a predetermined time. This predetermined time is called an unused determination time and is a multiple of unit time.

  Although the above-described unused determination time varies depending on the subject, generally, it may be specified as about 6 to 12 hours in consideration of sleep time and the like.

  For example, assuming that the unit time is 1 hour and the unused determination time is 12 hours, it is determined that there is an abnormality when the usage amount per hour is 12 times consecutively unused.

  Thereafter, when the unused state continues, it is determined as abnormal every unit time, the safety information is updated each time, and a notification is made.

  The above-mentioned continuation is a continuation counted from the previous use state. This unused report is canceled when the target person uses water, and it is useful information to the administrator if the report is also made at the time of cancellation.

  Although the above-described unused determination time can be basically changed by parameter setting, it may be used at a fixed time such as 12 hours, for example, without the setting time.

  However, if the unused determination time is too short, unauthorized reports can occur frequently, and if it is too long, it may be too late. Thus, the unused determination time largely depends on individual differences. For this reason, it is desirable to make it variable according to the subject if possible.

  In order to determine the unused determination time with individual differences, it is necessary to know the lifestyle of the subject. Therefore, if it is possible to view continuous unit time data of the subject and provide a function for confirming the lifestyle from the amount of water used by the subject, it will be a reference for determining the unused determination time. By referring to the data for about a week, you will be able to grasp the general rhythm of life.

  The unused determination time may be specified longer at first, and when a detailed lifestyle is found, it may be determined with reference to the sleep time of the person to be monitored and the time to go out.

  When the subject is in an emergency, it may be in a state of draining water, such as during bathing. It is the release determination means that can make a report even in such a state.

  The release determination is determined to be abnormal when a state in which the usage amount per unit time is a fixed amount continues for a fixed time. This fixed time is called a release determination time, which is a multiple of the unit time.

  The above-described release determination time may be set to about 3 to 5 hours because it is unlikely that water will be released for many hours in ordinary households.

  This release determination time is basically variable, but it may be used as a fixed time, for example, 3 hours or the like, omitting the setting work.

  For example, when the minimum measurement amount is 1 liter, the unit time is set to 1 hour, and the release determination time is set to 4 hours, it is determined to be abnormal when the usage amount per hour is the same amount 4 times in a row. The If the amount used is not the same, it is not determined to be abnormal.

  Thereafter, when the state of the same amount continues, it is determined to be abnormal every unit time, and a notification is made each time.

  This notification of release determination is canceled when there is a change in the water usage of the target person, and it is useful information to the manager if notification is made at the time of cancellation.

  In addition, if the discharge determination is also performed for the dwelling unit in which the safety monitoring function is invalidated by the parameter setting means, it is possible to serve for water saving while also detecting water leakage and artificial water discharge state.

  Basically, it is not necessary to specify a predetermined value for the concept that the amount of use of the discharge determination means described above is constant. However, if the minimum measured amount of the water meter is as large as 10 liters, the amount of water used is rounded to this minimum flow rate. Therefore, even in the case of normal use, there is a risk that it is determined as abnormal. In such a case, it is preferable to increase the accuracy by extending the determination time.

  In addition, when a water meter with a minimum measurement amount of 100 liters or 1000 liters is used, the detected amount of water is further rounded, and the above-described constant amount cannot be obtained. Even in such a case, it is possible to determine the release if a threshold is set for the amount used for the release determination, and it is determined that there is an abnormality when the threshold is exceeded for a predetermined time.

  In addition, depending on the usage environment, when using a small water meter with a minimum measurement volume of 1 liter or less, the measurement volume may change due to changes in water pressure due to the use of nearby water supply. might exist.

  As described above, since the safety determination of the subject is determined based on the usage amount per unit time, the unused determination time, and the release determination time, the shorter the unit time and the determination time, The person in charge can rush to the target person quickly.

  The absence change means is a function for changing the monitoring target to the absence state when the person to be monitored goes out for a long time due to travel or hospitalization.

  When the person to be monitored is found to be out of office such as long-term overnight stay, the manager or the person in charge can specify to the centralized meter reading device that the object person is out of absence.

  During this absence, the target dwelling is not monitored by water usage. Monitoring by the amount of water used is a notification by updating safety information by an unused determination means and a short-time unused detection means. In this case, determination may not be performed, or notification may not be performed. This state is continued until the subject returns home and uses the water to stay home.

  Even if an emergency occurs and an administrator rushes to the subject's home and reaches a state such as hospitalization, it is only necessary to leave this state.

As described above, in the absence transition means, the absence state is designated by an artificial operation, and the release is automatically performed.
By this absence changing means, it is possible to prevent unauthorized reporting when the target person is absent and the water supply is not used.

  By updating the above-mentioned safety information and making a notification to all registered managers when transitioning to absence or at-home status, all managers can grasp the situation and be useful. It is.

  The safety information is updated when it is determined that there is an abnormality, when the abnormality is canceled, and when the absence is changed.

  An e-mail in which this safety information is described is transmitted as the contents of the report to the report destination such as an administrator registered in advance by the parameter setting means.

  The notification when the above-described safety information is updated is made by electronic mail via the Internet line. If it is an electronic mail, a special apparatus is unnecessary and it can be easily realized by a personally owned terminal such as a mobile phone or a smartphone.

  The contents of the mail to be reported include information on the contents of the report together with the name and room number of the subject. In addition, if other report contents currently occurring and information on absence are described in the same message, it is useful information for the administrator.

  Administrators and persons in charge are not always fixed personnel, and if there are many people to be monitored, it is difficult for administrators and persons in charge to grasp the information of all the persons to be monitored . Some may not be familiar with the person being monitored.

  Therefore, it is possible to preset the name, age, gender, contact information, remarks, etc. of the monitoring target in the parameter setting means described above, and describe this information of the monitoring target in the email to be reported By doing so, in the unlikely event of a report, the administrator or the person in charge can immediately grasp the person to be monitored and can quickly respond to the next action such as contacting the person concerned. Also, in the remarks, it is possible to describe various information such as the contact information for the close relative of the monitoring target person.

  Further, by changing the report destination mail address by the parameter setting means, even when the manager or the person in charge is on duty, it is possible to cope with it by appropriately changing the report destination address.

  In addition, as described above, the parameter setting means can be operated from a remote place by the remote operation means, and thus is an effective function for actual operation.

  In addition, if a function is provided that can send water usage data such as daily and monthly reports of each dwelling unit to an email and send it to a water meter reader, normal meter reading work can also be realized without going to the site, as a centralized meter reading device. The introduction advantage can be improved.

  The absence state of the above-described absence change means is mainly specified by operating the centralized meter reading device main body. This is performed via an Internet line, such as a web browser of an external information processing terminal such as a PC, tablet, or smartphone. Therefore, by accessing the web server function of the centralized meter reading device, it is possible to operate remotely without requiring special software. This is called remote control means.

  If it is possible to perform the above-described parameter setting means in addition to the absence change by this remote operation, it is possible to input characters such as information on the monitoring target person with a PC or a smart phone, which can be changed more easily.

  In addition, if the measurement data per unit time that has been continued until now can be browsed by the web browser of the external information processing terminal, it is necessary to grasp the lifestyle of the target person and specify the unused duration. Helpful.

  The Internet line connected to the communication means is basically a line such as FTTH provided by a communication company or the like, but a wireless communication line provided by a mobile phone company or the like may be used. In general, it is necessary to use a modem or a router for connecting to a provider.

  When using e-mail, a mail server address, a sender e-mail address, an authentication password, etc., separately provided from a provider or the like are required.

  The web server function described above must be performed in the same LAN environment as the centralized meter reading device. When performing from a remote location outside the same LAN, the Internet environment connected to the centralized metering device acquires a fixed IP address. There is a need to.

  The short time unused detection means performs detection every time a detection time zone (for example, 3 hours) for each dwelling unit has elapsed.

  The usage amount per unit time continuously stored in the target dwelling unit is divided every day (24 data if the unit time is 1 hour, 8 data if the unit time is 3 hours, etc.), and data for a plurality of days is obtained. The number of days may be the number of the most recent consecutive days, or may be arranged for each day of the week from the stored data.

  The data of the detection time zone for the above-mentioned multiple days is extracted, and the total value of the extracted data is divided by the number of days, thereby calculating the daily average value of the detection time zone.

  The above-mentioned calculated average value and the current total value in the same time zone are used as a criterion. If the calculated average value is in use and the current total value is unused, the safety information is updated and notified.

  In the above-described unused determination means, a notification is given when the water usage is continuously unused for a predetermined time (6 to 12 hours, etc.). In this case, it is not possible to determine that the predetermined time has not passed at least. The detection time can be shortened by comparing past data using the unused time detection means.

  The detection time zone described above may be variable or may be a fixed value such as 3 hours.

This detection time zone may be determined by the error of the human behavior pattern.
For example, an action such as waking up in the morning and going to the toilet, washing the face, etc. is usually taken, but there are errors in the wake-up time and errors in the action time in the time zone of this action. Based on this, for example, if the unit time is 1 hour, the error is taken for 1 hour before and after, and the detection time zone is 3 hours.

  The short-time unused determination means cannot be introduced at first because it takes time until data is acquired, but can be implemented by increasing the stored data as time elapses.

  The number of data necessary for this short-term unused determination means requires stored data for about one week if the number of consecutive days, and about one month if detected on the day of the week. Since the detection accuracy increases as the number of consecutive days increases, the accuracy increases as the storage number of the storage means increases.

  The determination method by the short time unused detection means is based on the condition that the unit time is less than one day such as 1 to 12 hours.

  However, if there is a variation in the life rhythm of the subject, there is a possibility that the short-term unused determination means may not be able to detect it, so it is also necessary to perform the above-described unused detection means together.

  In the above-mentioned storage means, when there is no margin in memory capacity, for example, the measurement value is referred to every unit time without being continuously arranged in the memory area, and in the case of the unused determination means, it is not used. Judgment of use state, in the case of release judgment means, memorize the previous measured value per unit time, judge whether the current usage amount is the same as the previous time, each continuous counter etc. according to each judgment result If the process of incrementing or resetting is performed, it is not necessary to continuously store in the memory area, and the memory capacity can be saved.

  However, when the above method is used, the memory capacity can be saved, but the above-described monitoring of the life style of the monitoring target person and the short-time unused detection means cannot be used.

  In collective housing, there are dwelling units that do not require safety monitoring depending on vacancy conditions, age of each dwelling unit, family structure, and the like. Therefore, the safety monitoring function can be disabled for each dwelling unit by the parameter setting means.

  A dwelling unit in which the safety monitoring function is disabled is no longer judged to be safe by the unused judgment means and the short-time unused detection means, and the manager is not notified.

  In addition, the dwelling unit in which the safety monitoring function is disabled cannot perform absence designation by the absence changing unit, and the dwelling unit is not displayed on the screen of the centralized meter reading device or the screen of the external information processing terminal by the remote control unit.

  However, even if the safety monitoring function is disabled, the measurement and recording operation of the water usage amount of each dwelling unit is performed, and the function as a centralized meter reading device is achieved.

  Moreover, even if the safety monitoring function is disabled, the discharge determining means of each dwelling unit can make a determination, and it can be useful for saving water as well as detecting water leakage and an artificial water discharge state.

  In the parameter setting means, the mail addresses of a plurality of managers can be set as report destinations, and contact information such as close relatives can be specified for each dwelling unit, and it is possible to report to the family of the monitoring subject.

  In addition, the mail address that can be set by the parameter setting means can specify the address of the meter reader in addition to the report destination mail address, and the aggregated data such as the daily and monthly reports recorded and recorded can be transmitted only to the meter reader.

  In the centralized meter reading device according to the present invention, parameters necessary for other functions such as a site name, a name and room number of each dwelling unit, and an IP address can be set. If necessary, unit time, unused determination time, release determination time, etc. can also be set.

  A device that performs email notification has a function of sending a normal operation email once a day by fail-safe, but the above-mentioned absence state is only updated at the time of transition. If a list of subjects who are out of the office is included in the operation mail, it becomes more useful information.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an example of an overall system configuration diagram of a water volume centralized meter reading device having a safety monitoring function of the present invention.

  The water meters 21a to 21n installed in the apartment house 2 are the above-mentioned water meters that detect the water usage of each dwelling unit. Signals from the water meters 21a to 21n are measured by the measuring means 10 of the centralized meter reading device 1.

  The measurement data of each dwelling unit measured by the measurement unit 10 is stored and stored in the storage unit 12 for each unit time of each dwelling unit.

  In addition, as described above, the storage means 12 also stores the daily report value, monthly report value, annual report value, etc. of each dwelling unit. These data are made into a form and attached to the outgoing mail. It is also possible to transmit to the meter reader.

  As described above, the unused determination unit 13 determines the unused state of each dwelling unit based on the measurement data stored and stored in the storage unit 12 of the dwelling unit that is validated by the parameter setting unit 11. On the basis of the unused determination time, the safety information of the storage unit 12 of the dwelling unit is updated when the unused state is continuously used.

  As described above, the discharge determination unit 14 determines the discharge state of water in each dwelling unit based on the measurement data stored and stored in the storage unit 12, and discharges continuously based on the discharge determination time for each dwelling unit. In the case of the state, the safety information of the storage unit 12 of the dwelling unit is updated.

  As described above, the absence change means 15 switches between valid and invalid monitoring based on the amount of water used in accordance with the absence of the dwelling unit, which is enabled by the parameter setting means 11, and the state of being at home.

  In addition, when it is determined that the person to be monitored is out of the office for a long period of time or the like, the monitoring by water usage is invalidated by designating the absence state, the safety information in the storage means 12 is updated, and the person to be monitored is When the user goes home and uses the water supply, the monitoring based on the water consumption is automatically resumed, and the safety information in the storage means 12 is updated.

  As described above, the reporting unit 16 creates an e-mail describing the safety information such as the name of the corresponding dwelling unit (room number) and the reporting content based on the update of the safety information in the storage unit 12, and the parameter setting unit 11 is transmitted to the external information processing terminal 4 via the communication means 17 and the Internet communication network 3 to the report destination mail address set in advance.

  Note that the transmission of the e-mail by the reporting means 16 is not limited to reporting by updating the safety information, but a function of transmitting a normal operation message by the above-described fail safe, a function of periodically retransmitting the current report occurrence status, etc. You may make it provide.

  In addition, the above-mentioned parameter setting means 11 enables / disables the safety monitoring function, specifies the destination mail address, the absence status of the absence change means 15, and the other setting values are set values corresponding to each unit. Can be set by the display and buttons on the main body.

FIG. 2 corresponds to FIG. 1 described above, and the same portions are denoted by the same reference numerals and description thereof is omitted.

  As described above, the short-time unused detection means 19 is based on the measurement data stored in the storage means 12 of the dwelling unit that is validated by the parameter setting means 11 and data for a plurality of past days of the dwelling unit. Based on this, the safety information in the storage means 12 is updated by determining the usage state and unused state of the water supply in the same detection time zone as the present.

  As described above, the remote operation means 18 responds to the request from the external information processing terminal 4 equipped with the browser function via the communication means 17, so that the monitoring target person of the absence change means 15 sends the request from the external information processing terminal 4. The absence status can be specified. In addition, the parameter setting means 11 can be used to set information such as the e-mail address of the reporting destination of each dwelling unit, the name, gender, age, and contact information of the monitoring target person of each dwelling unit, and other settings as described above. In addition, the measurement data of each dwelling unit stored and stored in the storage unit 12 and the current report occurrence status can be browsed.

  In this way, switching to the absence state, setting of each parameter, and the like can be set and viewed even remotely from the Internet communication network 3.

  With reference to the timing chart which shows an example of the report generation | occurrence | production by the unused determination means based on this invention of FIG. 3, an example of operation | movement by the unused determination means 13 in the said structure is demonstrated using the example of a certain dwelling unit. .

  The horizontal axis of FIG. 3 shows time, the upper part of the vertical axis shows the measured water usage, the middle part shows H, the unused state is L, and the lower part is abnormal as the judgment result of the unused judgment means 13. This determination is indicated by H, and normal determination is indicated by L. Furthermore, the unused determination time is set to 12 hours as an example, and is indicated by a vertical dashed line. In addition, a state is shown in which measurement is performed from the most recent unused state t0 to the lapse of the unused determination time at t1.

  Here, FIG. 3 shows a state where the water usage is determined to be unused from t0 to t1 for 12 hours of the unused determination time, and the determination result is an abnormality determination H.

  With reference to the timing chart which shows an example of the report generation | occurrence | production by the discharge | release determination which concerns on this invention of FIG. 4, an example of operation | movement of the discharge | release determination means 14 in the said structure is demonstrated using the example of one certain dwelling unit.

  In FIG. 4, as in FIG. 3 described above, the horizontal axis indicates time, the upper part of the vertical axis indicates water usage, the lower part indicates H for abnormal determination, and L indicates normal determination. Furthermore, the release determination time is set to 2 hours as an example, and is indicated by a vertical alternate long and short dash line.

  Here, FIG. 4 shows a state in which the amount of water used is determined to be a constant amount from 3 hours during the release determination time, from t0 to t1, and the determination result is an abnormality determination H.

  With reference to the diagram showing an example of comparing the data for a plurality of days with the current water usage by the short-term unused detector according to the present invention in FIG. An example of the determination method will be described using an example of a certain dwelling unit.

  As an example, in FIG. 5, 24-hour data for one day from 1:00 to 0:00 stored and stored in the storage unit 12 is shown in the table as data for a plurality of days (for seven days).

  The determination by the short-time unused detection means 19 is that the total value for the past 7 days in the past detection time zone in the gray solid line frame in FIG. 5 is “96”, the average value per day is “13.7”, about Since it is “14”, it is determined that it is a time zone in which water usage is permitted in the past seven days, and the total value of water usage in the current detection time zone is “17”. It is recognized and judged to be normal. On the other hand, in the same time zone, for example, when the total value of the detected current water usage is in the above-described unused state, it is determined that there is an abnormality.

  That is, in the example of FIG. 5, it is determined whether the water supply is normally used during the time period based on the average value of the detection time period for the past seven days, and compared with the water supply usage state in the current detection time period. By doing so, the determination time when an abnormality occurs in the resident can be shortened.

  An example of a screen for setting the absence state by the centralized meter reading device of FIG. 6 will be described.

  The setting screen example of FIG. 6 is a screen example for performing absence setting on a display device (for example, a touch display module) provided in the centralized meter-reading apparatus.
