Description

  The present invention relates to a life monitoring system that monitors and confirms the safety or living conditions of a resident from door to door.

  As this type of technology, for example, the technology described in Japanese Patent Application Laid-Open No. 2003-6337 (Patent Document 1) is known. This technology uses a standard usage database in which individual data on standard usage of public services such as electricity, gas, and water for each individual contractor's house is stored on a server operated by a living condition confirmation company, and each individual contractor's house. Received data that detects the usage status of public services such as electricity, gas, water, etc., and received data on the usage status of public services such as electricity, gas, water, etc. received by individual receivers at the receiving unit Comparing individual data of standard usage of the individual contractor's house stored in the standard use database to determine whether it is normal or abnormal, and abnormal when the determination unit determines that it is abnormal A contractor is provided by providing means for notifying the occurrence of anomalies and observing the usage status of public services such as electricity, gas, and water in each individual contractor's house remotely over the network. To determine the presence or absence of an abnormality of the living conditions in, if it is determined that the abnormality is that to be able to have accurate care, supported by the speedy for the contract's house in question is informed that an abnormality has occurred.

JP 2003-6337 A

  In the technology described in Patent Document 1, power consumption is measured at the receiving power end of each house, a standard consumption database for each house is created based on the individual standard data, and the daily power consumption and each house's power consumption are created. By comparing with the standard consumption data pace at the time of health, it is judged whether there is a health disorder. Therefore, since it is necessary to collect and accumulate data immediately after system operation, it is impossible to determine whether or not a health disorder has occurred during the period until the individual standard consumption database is generated. Furthermore, a period for accumulating the individual standard consumption database that can be judged every time a resident moves out and newly moves in is required.

  Moreover, in the said technique, in order to detect the usage condition of electricity, the electric power measurement means is installed in the power receiving source of every door, and electric power consumption is measured. However, for example, taking an air conditioner as an example, the air conditioner is mainly used in summer and winter, and power consumption varies depending on the outside temperature. Since the amount of power consumed by the air conditioner is larger than the amount of power consumed in the life derived from the resident's life, it is difficult to determine the presence / absence of living power consumption and the time during which power is consumed. In addition, since the electric water heater also consumes a large amount of power, it is difficult to determine the presence / absence of power consumption and the time during which power is consumed, as in the case of an air conditioner.

  Therefore, the problem to be solved by the present invention is to enable the resident's living state to be monitored quickly even in the initial operation or initial occupancy of a system with a small number of data on the power consumption of each household.

  In order to solve the above problems, the present invention provides occupancy detection means for detecting that a resident is present in a room of each door, overall power consumption measurement means for measuring the overall power consumption of each door, and each door. Provided with individual power measuring means for measuring the power consumption of each individual power consuming device installed in the door, and a monitoring device provided for each door, connected via the monitoring device and the communication device, from the monitoring device A life monitoring system including a monitoring center that collects and manages life information of residents of each house with reference to the output of each means. Note that problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

  According to the present invention, it is possible to quickly monitor the living state of a resident even in the initial operation or the initial occupancy of a system with a small amount of data on the power consumption of each household.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an example of a system configuration of a life watching system according to an embodiment of the present invention. The life monitoring system 100 according to this embodiment includes a monitoring center 21, a home server 19 for each door (same for each home, each room, or each room: the same applies hereinafter), a centralized monitoring terminal 27 for service providers, and each door 1 The resident display device 28 and the network 20 that connects these units so as to communicate with each other are basically configured. Note that the home server 19 and the display devices 28 for each resident 1 are provided in a number corresponding to the number of occupants or the number of homes. However, the home servers 19 are not door-to-door, and it is possible to arrange several homes together. It is only necessary that the home server 19 can detect or grasp the state of each home 1 when the home servers 19 are put together. In the present embodiment, for the sake of explanation, three rooms, Room 101 1a, Room 102 1b, Room 103 1c, will be illustrated and described. Needless to say, the number increases according to the number of houses in apartments and condominiums.

  It should be noted that parts that can be regarded as the same or the same are given the same reference numerals, and when distinguishing each part of each living room 1, subscripts a, b, and c are attached, but they are collectively described. In this case, the subscripts a, b, and c are omitted. Therefore, in FIG. 1, the subscripts a, b, and c are added, but the same applies to each of the living rooms 1 a, 1 b, and 1 c, and thus the subscripts a, b, and c are omitted in the description.

  A living room (room 101 1a, room 102 1b, room 103 1c) 1 which is a residence of a resident, for example, has an electric water heater 3, an air conditioner 4, a television 5, a refrigerator 6, a microwave oven 7, and a lighting fixture 8. And a washing machine 9 are provided and connected to the commercial power source 2. The power supply 2 is supplied with AC 100V, thereby enabling power supply to each of the power consuming devices. A drawn-in power sensor 10 is installed in the immediate vicinity of the power supply 2, and the total power supplied from the power supply 2 to each room 1 is measured by the drawn-in power sensor 10. An electric water heater power sensor 11 is installed in the power source of the electric water heater 3, and an air conditioner power sensor 12 is installed in the power source of the air conditioner 4. Further, an external locking sensor 14 is installed on the external door 13 of each living room 1.

  The retraction power sensor signal 15 of the retraction power sensor 10, the electric water heater power sensor signal 16 of the electric water heater power sensor 11, the air conditioner power sensor signal 17 of the air conditioner power sensor 12, and the external locking sensor signal 18 of the external locking sensor 14 are Input to the home server 19 of each living room 1. Based on this external locking signal 18, it is determined that there is no presence by external locking and the presence of the room by external unlocking.

  The various sensor signals 15, 16, 17, and 18 from the pull-in power sensor 10, the electric water heater power sensor 11, the air conditioner power sensor 12, and the external locking sensor 14 are transmitted from the home server 19 of each room 1 through the network 20. The data is sent to the data input / output control unit 22 of the watching center 21. The watching center 21 includes a data input / output control unit 22, a host computer 23, and a database 24. The host computer 23 includes an input unit 25 and a display unit 26 for management and operation. The input unit 25 is a known input device such as a keyboard or a touch panel, and the display unit 26 is a known display device such as a liquid crystal display. The network 20 is a communication network such as the Internet or a public telephone communication network.

  The host computer 23 uses, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown) mounted on the host computer 23 via the ROM, HDD (Hard Disc Drive), or the network 20. The downloaded program is expanded on the RAM or HDD, and the processing defined by the program is executed while using these storage devices as buffers, and each part is controlled. The database 24 stores and manages specific data necessary for watching life, and can be easily searched and extracted by the host computer 23. In the present embodiment, the host computer 23 sequentially executes processes according to the program, extracts the resident's living power consumption pattern, watches the resident's life, and makes a safety decision.

  Further, a centralized monitoring terminal 27 for service providers and a display device 28 for each room occupant are connected to the network 20. As a result, the monitoring results determined by the host computer 23 are sent via the network 20 to the service provider centralized monitoring terminal 27, the display device 28a for the 101st room, the display device 28b for the 102nd room, and the occupant 103's room. Sent to the display device 28c, and the result of watching is displayed on each display device 28. The door exterior locking sensor 14 can obtain the same effect even in an in-room detection device (not shown) in which an in-room button and an out-going button are provided in the room.

  FIG. 2 is a flowchart showing a processing procedure of the consumption power consumption calculation process executed in the watching center 21.

In this process, the host computer 23 first records the presence / absence of each house in the database 24 (step 1). Next, the power consumption measurement data of each house obtained from the power consumption sensor signal 15 detected by the power consumption sensor 10 is recorded in the database 24 (step 2). The recording result is (1). Similarly, air conditioner power measurement data of each house obtained from the air conditioner power sensor signal 17 detected by the air conditioner power sensor 12 is recorded in the database 24 (step S3). The recording result is (2). Similarly, the electric water heater power measurement data of each house obtained from the electric water heater power sensor signal 17 detected by the electric water heater power sensor 11 is recorded in the database 24 (step S4). The recording result is (3). Then, the air conditioning power measurement data and the electric water heater power measurement data are subtracted from the drawn-in power measurement data recorded in step 2 to calculate the life power consumption of each house that is not affected by the temperature and recorded in the database 24. (Step 5). The recording result is (4). That is, the recording result recorded in step 5 is
(4) = (1)-(2)-(3)
It is.

  The living power consumption calculation process shown in FIG. 2 is executed each time the measurement data of each power sensor 10, 11, 12, 13 is recorded in the database 24 at each preset time and updated. In addition, the timing which measures power consumption can be arbitrarily set, for example according to a monitoring object.

  FIG. 3 is a flowchart showing the processing procedure of the grouping process executed in the watching center 21.

  First, the host computer 23 creates an hourly living energy consumption database for each day of staying in the room from the living electricity consumption data for each hour calculated in the living energy consumption calculation process of FIG. 2 (step 11). . Next, the hourly living power consumption pattern for each similar house is grouped together in the daily hourly living energy consumption database created in step 11 for each day (step 12). Here, the similar door is a door (living room) 1 in which the daily power consumption pattern of each door in the room is similar, and a group is formed for each similar door. To do. Then, the hourly living power consumption pattern, which becomes the standard for each house by group, is created from the grouped hourly living electricity consumption pattern group data created in step 12 (step 13). In other words, a household-specific hourly power consumption pattern is created for each group of similar households with a standardized state of power consumption.

  FIG. 4 is a flowchart showing a processing procedure of a life change determination process executed in the watching center 21. The processing of the flowchart of FIG. 4 is executed using the processing results of the flowcharts of FIGS.

  In this processing procedure, the host computer 23 first determines whether a resident is present based on the sensor signal of the external locking sensor 14 (step 21). If the resident is in the room, the process proceeds to the life change determination process, and if not, the process is completed.

  In the life abnormality determination process, the daily power consumption pattern for each room of the living room 1 to be monitored is selected from the database 24 created in step 11 (step 22). And the living power consumption pattern according to standard time corresponding to the living pattern of the resident is selected from the living power consumption pattern according to the standard time according to each house created in step 13 (step 23). Next, the household power consumption pattern for each hour selected in step 22 is compared with the standard hourly household power consumption pattern obtained in step 23 (step 24).

  From the comparison result of step 24, it is determined whether or not there is a difference more than a specified difference between the household power consumption pattern by time and the standard power consumption pattern by time (step 25). If there is a difference greater than the standard, it is determined that the resident's life change has occurred, the resident's life change is reported (step 26), and the process is completed. If there is no difference exceeding the specified value, it is determined to be normal, and further, it is determined whether there is no change in the household-specific hourly power consumption pattern within the specified time (step 27). If there is no change, it is determined that a life change has occurred, the resident's life change is reported (step 28), and the process is completed. If there is a change, it is determined as normal and the process is completed. The “regulation” serving as a determination criterion is determined, for example, by setting a resident safety threshold in advance by statistical pattern processing. Further, the term described as “consumer power consumption” in the description of the present embodiment can also be described as “consumer power consumption”. Both show the same thing.

  In the flowchart of FIG. 4, the standard hourly consumption power consumption pattern created in step 13 of FIG. 3 is selected in step 22 and compared using the power consumption pattern in the subsequent steps. Comparison can be made using the integrated value of power consumption to make a watch determination.

  In this way, by subtracting the measurement data of the air conditioner power sensor 12 and the measurement data of the electric water heater power sensor 11 from the measurement data of the pull-in power sensor 10, the living power consumption for each house time not affected by the temperature can be reduced. Since it is calculated and the living state is determined, it is possible to determine a change in the resident's activity such as a life abnormality under conditions that do not make a false determination from the power data. In addition, the standard hourly power consumption, which is a criterion for determining the hourly life power consumption, is that many similar hours-by-hour lives can be obtained even when there is little past accumulated data in the room 1 to be diagnosed by grouping. Since the determination is made based on the standard hourly living electric power consumption obtained from the electric power consumption data, the living state can be determined in a short period of time when the group of hourly living electric power data is found even when the resident is new.

  As described above, according to the present embodiment, the following effects can be obtained. In the description of the effects in the following embodiment, each component in the present embodiment is indicated by parentheses in each component in the claims, or given a reference symbol, to clarify the correspondence between them.

  (1) External lock sensor 14 (occupancy detection means) for detecting that a resident is present in the room of each door 1, and retractable power sensor 10 (total power consumption measurement) for measuring the total power consumption of each door 1 Means), and an electric water heater power sensor 11 for measuring the power consumption of each individual power consuming device installed in each door 1, and an air conditioner power sensor 12 (individual power measuring means). ) And the home server 19 (monitoring device) via the network 20 (communication means), and outputs of the sensors 10, 11, 12, 14 (means) from the home server 19 (monitoring device). According to the life monitoring system 100 including the monitoring center 21 that collects and manages the living information of the residents of each door 1 with reference to the life power consumption related to life Since extraction can watch the living conditions of rapidly tenants in operation the initial and tenants earlier systems the number of data of life power consumption of each household 1 is small.

  (2) The watching center 21 uses the power consumption measurement result of each time measured by the drawn power sensor 10 (total power consumption measuring means) and the power consumed by a power consuming device having a large power consumption set in advance. By subtracting, life power consumption by hour [hourly life power consumption] is calculated, so it is possible to extract only life power consumption related to daily life, and it is possible to ensure life changes from the state of life power consumption. Can be judged.

  (3) Since the preset power consuming devices having a large power consumption are the air conditioner 4 and the electric water heater 3, the electric water heater 3 in which the power consumption greatly fluctuates due to seasonal factors such as temperature and water temperature, and The power consumption of the air conditioner 4 can be eliminated and the life power consumption related to life can be extracted.

  (4) The monitoring center 21 groups [step 12] similar household power consumption patterns by time based on hourly living power consumption when the resident is in the room, and is standardized from the grouped data. Because it creates a daily power consumption pattern by group and by household [Step 13], there is no need for a period for storing the standard data for each resident to determine whether a resident is safe. When the group of electric power data is found, it is possible to make a judgment on life changes.

  (5) Since the occupancy detection means is an external locking sensor 14 (external locking detection device) provided on the external door 13 of each door 1, the presence / absence of the occupant's occupancy can be easily determined by the presence / absence of locking from the outside. Can be confirmed.

  (6) Since the home server 19 (monitoring device) is provided for each house, it is possible to make a judgment on life changes independently for each house 1.
