FIG. 1 is a schematic diagram showing the overall configuration of the housing condition confirmation system of the present invention. FIG. 2 is a diagram illustrating a connection state of the in-house information transmission device 2. FIG. 3 is a block diagram showing the configuration of the management server 5.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the overall configuration of the housing condition confirmation system of the present invention. This housing state confirmation system can simultaneously perform information processing regarding a plurality of users' homes and provide the information to the users. In this house state confirmation system, an in-house information transmission device 2 is installed in each house 1 of the user. The house 1 may be a detached house or an apartment house.

  As will be described later, a sensor for detecting the amount of water, gas, and electricity used is connected to the in-house information transmitting apparatus 2. The in-house information transmitting device 2 is connected to the Internet communication network 4. The in-house information transmission device 2 sends data relating to water, gas, and electricity usage detected by the sensor to the management server 5 via the Internet communication network 4. The management server 5 is installed not in each house 1 but in a data center or the like, and is connected to the Internet communication network 4. The management server 5 performs intensive information processing on the housing 1 of many users.

  The management server 5 receives the data sent from the in-house information transmission device 2 of each user, and performs data processing such as tabulation of water, gas, and electricity usage and pattern comparison for each user. That is, the identification code without duplication is given to the in-house information transmission apparatus 2, and the data of the identification code is added to the transmission data. The management server 5 classifies the transmission data for each user by the identification code added to the transmission data, and performs data processing for each user.

  The management server 5 creates history information, transition information, comparison information, alarm information, and the like related to usage of water, gas, and electricity for each user and provides the information to each user. Moreover, the management server 5 judges the state of a user's house from those usage pattern, and provides each user with information regarding the state of the house.

  The user can save water, gas, electricity, etc. by the information provided from the management server 5, and can check the state of the house. The configuration of the management server 5 will be described in detail later. Information is provided from the management server 5 to each user via the Internet communication network 4.

  Each user can refer to information from the management server 5 by the terminal device 6 or the wireless terminal device 7 used by the user. As the terminal device 6, a normal personal computer or the like can be used. As the wireless terminal device 7, a mobile phone or the like that can refer to Internet information can be used. Similarly to the terminal device 6, various information regarding the house can be referred to in the wireless terminal device 7.

  When a user refers to information about his / her house, the terminal device 6 or the wireless terminal device 7 is used to connect to the management server 5 via the Internet communication network 4. And if you enter your login name and password and are authenticated, you can refer to the information. That is, only a legitimate user who is authenticated by the login name and password can refer to information related to his / her home.

  In the housing status confirmation system according to the present invention, the in-house information transmitting device 2 is installed in the user's house 1 and data is collected and various processes are performed by the management server 5. The cost of using the system can be reduced. In addition, since various processing contents and charge tables are stored in the management server 5, they can be easily corrected and changed, and can quickly respond to changes in the water, gas, and electricity charge systems. .

  FIG. 2 is a diagram illustrating a connection state of the in-house information transmission device 2 installed in the house 1. A water usage sensor 31 that detects the amount of water usage, a gas usage sensor 32 that detects the amount of gas usage, and an electric usage sensor 33 that detects the amount of electricity usage are connected to the in-house information transmission device 2. Those sensors constantly input data relating to the amount of use to the in-house information transmission device 2.

  The water usage sensor 31 is a flow sensor inserted and installed in a water supply pipe of a supply source in a house, and generates a number of electrical pulses corresponding to the volume of tap water flowing in the pipe. The gas usage sensor 32 is a flow sensor inserted and installed in a gas supply pipe of a supply source in a house, and generates a number of electrical pulses corresponding to the volume of gas flowing in the pipe. As these flow sensors, general flow sensors such as those using an impeller rotated by a fluid can be used.

  The electricity usage sensor 33 uses a detection coil that detects the current flowing through the power wiring of the supply source. In a general house, the power factor of the electric power used is close to 1, and the effective value of the voltage is almost constant. Therefore, even with a sensor that detects only the current, information on the amount of electricity used can be obtained with sufficient accuracy. However, in order to obtain more accurate information on the power used, a sensor that detects both voltage and current and can distinguish between active power and reactive power may be used.

  The in-house information transmission device 2 sends information from these sensors to the management server 5 via the Internet communication network 4. The in-house information transmitting apparatus 2 is connected to the Internet communication network 4 via a wireless LAN (local area network). That is, the in-house information transmitting apparatus 2 is connected to the wireless LAN router 22 by a wireless signal via the wireless LAN transmitter / receiver 21 and connected to the Internet communication network 4 via the wireless LAN router 22. The in-house information transmitting apparatus 2 may be connected to the Internet communication network 4 via a wired LAN, or may be directly connected to the Internet communication network 4 not via a LAN.

  The in-house information transmitting apparatus 2 collects data regarding the amount of water, gas, and electricity used at a predetermined time every predetermined time, and sends the data to the management server 5. Note that a unique identification code is assigned to the in-house information transmission apparatus 2, and data (identification information) of the identification code and time information are added to the transmission data. The predetermined time is, for example, 10 minutes.

  That is, the in-house information transmission device 2 has an integrated value of the number of pulses from the water usage sensor 31 for 10 minutes every 10 minutes, an integrated value of the number of pulses from the gas usage sensor 32 for 10 minutes, and an electric consumption. An average value for 10 minutes of the current value detected by the sensor 33 is obtained. Then, identification information and time information are added to the data and sent to the management server 5.

  Here, the time interval (predetermined time) at which the in-house information transmitting apparatus 2 transmits data is 10 minutes, but is not necessarily limited to 10 minutes, and the predetermined time is 1 minute, 2 minutes, 5 minutes. Other times may be used. However, considering the change time of the house state and the load on the management server 5, the predetermined time is preferably about 10 minutes.

  In addition, here, the in-house information transmitting apparatus 2 adds the identification information and the time information to the usage amount data, but the time information is not necessarily added. For example, the in-house information transmitter 2 is set to send data at the time of 0 minutes, 10 minutes, 20 minutes,..., 50 minutes every hour, and the time information estimated from the reception time on the management server 5 side is used. You may make it add to quantity data. Even in this case, it is preferable to add information such as a serial number indicating the transmission order to the usage amount data in consideration of the uncertainty of the transmission time until the arrival of information on the Internet.

  FIG. 3 is a block diagram showing the configuration of the management server 5. As the management server 5, a normal server computer can be used. The management server 5 is provided with a CPU 51 that performs various data processing and operations. The CPU 51 can perform various kinds of information processing by accessing a memory 53 including a ROM, a RAM, and the like through a bus 52 and accessing other input / output circuits and the like.

  The CPU 51 operates according to a system program and data such as BIOS stored in the ROM section of the memory 53 and a program and data loaded to the RAM section of the memory 53. First, an OS (operating system), which is a basic program, is loaded from the fixed disk device 54 into the RAM unit.

  A fixed disk device 54 as an auxiliary storage device is connected to the bus 52. An OS program to be executed by the CPU 51 and other programs are stored in the fixed disk device 54, and these programs are loaded from the fixed disk device 54 to the RAM section of the memory 53 as appropriate.

  A display unit 56 for displaying characters and graphics and an input unit 57 for an operator to input data are connected to the bus 52 of the management server 5 via an interface circuit 55. A CRT, a liquid crystal display, or the like can be used as the display unit 56, and a keyboard, a touch panel, or the like can be used as the input unit 57. Further, the management server 5 is provided with a communication circuit 58, and the management server 5 is connected to the Internet communication network 4 via the communication circuit 58.

  The RAM 53 of the memory 53 is loaded with an information recording program 531, an aggregation program 532, a state determination program 533, a data creation / transmission program 534 and the like. The information recording program 531 receives the data regarding the amount of water, gas, and electricity used from the in-house information transmitting device 2 in each house 1 and records it in the fixed disk device 54. The information recording program 531 discriminates the user from the identification information added to the usage data, classifies the data related to the usage and the time information for each user, and records them as the recording data 543 in the fixed disk device 54. To do.

  The aggregation program 532 performs various aggregation processes and statistical processes on the usage data of the recording data 543. The aggregation program 532 processes the usage data so as to be useful index information for the resource saving and energy saving behavior of the user. For example, the amount of water, gas, and electricity used is aggregated as an aggregate value for each predetermined period such as 1 hour, 1 day, 1 week, 1 month, or the amount used is converted into usage charges or carbon dioxide emissions I do. These aggregation results can be displayed as a bar graph or a line graph. The totaling result is stored in the fixed disk device 54.

  The state determination program 533 is a program that determines the state of the house from each usage pattern of water, gas, and electricity. The state determination program 533 determines the state of the house and the resident's behavior from the usage patterns of water, gas, and electricity, that is, the level of usage, the duration, the number of repetitions, and the time interval of repetition.

  For example, in a hot water bath, the amount of water supply is approximately 200 to 240 liters (L), and water and gas are used simultaneously. The supply duration of water and gas is approximately 15 to 20 minutes. When such a usage pattern appears, it can be determined that the resident of the house has performed bathing in the bath.

  In the case of dishwashing by hot water supply in the kitchen, water and gas are used simultaneously and intermittently, and the amount of water supply is about 5 to 20L. In the case of washing by an automatic washing machine, water and electricity are used alternately, the amount of water supplied at one time is 20 to 80 L, and the power consumption during washing and dehydration is about 100 to 200 W. When the dryer is also operated after washing, the power consumption of the dryer is 1-2 kW, and the duration is about 1-2 hours.

  Moreover, when a resident goes to a toilet, the supply amount of the wash water after use is 5-6L and is substantially constant. This resident's toilet behavior is characterized by water usage, which can be fairly clearly judged. The use of a microwave oven or an air conditioner can be determined from the electricity usage pattern. The microwave oven has a relatively short power consumption of 500 W to 2 kW and a duration of about 1 to 5 minutes. The air conditioner periodically increases and decreases in power consumption of approximately 300 W to 1 kW, and has a relatively long duration of 1 to 10 hours.

  Typical usage patterns for typical resident behavior and housing conditions as described above are stored in the fixed disk device 54 as reference patterns. The state determination program 533 compares the actual usage pattern of water, gas, and electricity with a plurality of reference patterns, and records the housing state and resident behavior together with the time when the conditions of the reference pattern are met. To do. The record of the house state and resident behavior is stored as transmission data 544 of the fixed disk device 54.

  The user can refer to the information on the house state and the resident behavior regarding his / her house by logging in to the management server 5 using the terminal device 6 or the wireless terminal device 7. For example, you can see information about when an elderly person who should be at home went to the bathroom, and whether the bathing hot water that was requested by the child at home was actually being executed. . Moreover, if the child who goes to school goes home and does hand-washing or going to the toilet, those actions and the time can also be confirmed.

  Moreover, even if it is not a resident's action, when it sets so that the hot water filling of a bath may be performed automatically by a timer function etc., it can be confirmed whether the hot water filling is implemented normally. Even when the reserved rice cooking is set by the timer function, it can be confirmed whether or not the rice cooking is being carried out normally. As a result, it is possible to confirm in advance before returning home whether a reservation for cooking rice has been forgotten or an operation error has occurred.

  The data creation / transmission program 534 converts the tabulation results, conversion results, and the like tabulated by the tabulation program 532 into data in a format that can be easily recognized by the user, and uses these data in response to user requests. This is a program to be sent to the terminal device 6 or the wireless terminal device 7. The tabulation results and conversion results are converted into bar graphs and line graphs and stored as transmission data 544 of the fixed disk device 54.

  Moreover, it can be set with respect to the data preparation transmission program 534 so that a warning signal may be transmitted to a user's terminal device by the presence or absence of a specific action of a resident. By setting such a setting for the data creation / transmission program 534 of the management server 5, for example, when the resident has not been in the toilet for more than 6 hours, It can be said that the alarm signal is notified when the gas is used for one hour or more.

  Various types of information of the transmission data 544 are formatted in an easy-to-read data format such as a graph or a table. The data sent to each user is created in a markup language such as HTML (Hyper Text Markup Language) or XML (eXtensible Markup Language), and each user can use normal browsing software via the Internet communication network 4. (Browser) can be referenced.

  Next, the fixed disk device 54 stores a user table 541 in which information about users is used as a table. The user table 541 stores user identification information such as the user's address and name, information on the identification code of the in-house information transmitting apparatus 2, user authentication information such as a login name and password, and the like. Note that highly confidential information such as passwords is encrypted and stored. The user table 541 also stores the types of water, gas, and electricity charge systems applied to the user.

  Further, the fixed disk device 54 stores a charge table 542 in which the charge system for water, gas, and electricity is a table. The charge table 542 stores all charge systems for water, gas, and electricity in the area to which the user's residence belongs. If the unit price varies depending on the season (summer price, winter price, etc.) and usage time (nighttime, daytime, peak time), such as electric power, such information is also stored.

  Further, the fixed disk device 54 also stores the recording data 543 and the transmission data 544 as described above. The recorded data 543 is data of time and water, gas, and electricity usage amounts that are classified and stored for each user by the information recording program 531. The transmission data 544 is data to be provided to the user created by the data creation / transmission program 534.

  The management server 5 configured as described above receives the data sent from the in-house information transmission device 2 of each user, and sums up the usage amount of water, gas, and electricity and compares the patterns for each user. Data processing is performed. Then, the management server 5 creates history information, transition information, comparison information, alarm information, and the like regarding the usage amount of water, gas, and electricity for each user, and provides them to each user. In addition, the management server 5 determines the state of the user's house from the usage pattern of water, gas, and electricity, and provides each user with information regarding the state of the house.

  The user can log in to the management server 5 and refer to data on the amount of water, gas, and electricity used in his / her house 1 at any time. These usage data can be referred to not only as volume and electric energy, but also as usage fee data converted into money and data converted into carbon dioxide emissions. Can be implemented.

  In addition, for the purpose of resource saving and energy saving, the target usage (upper limit value) of water, gas, and electricity is set, and when the actual usage is expected to exceed the target usage, It can also be set to send warning information.

  Furthermore, even when the user is away from home, such as when he is out, the user can check the state of the home residence and the behavior of the resident in the residence. This is particularly useful when a resident such as an elderly person or a young schoolchild is living in the house. The resident's abnormalities can be quickly detected by the resident's abnormal behavior or a long period of inactivity, and further, an appropriate response can be taken promptly. For this reason, the safety | security of the resident | resident in the house in the society where aging and small family progress can be improved significantly. In addition, when the equipment in the house is made to function by automatic driving or remote operation, the operating state can be confirmed, so that the safety of the automated house can be greatly improved.

  As described above, the housing status confirmation system of the present invention can provide both information for resource saving and energy saving and information for confirming the housing status including the resident's behavior. By providing a wide range of information by a single system, it is possible to provide such information to a user at a low cost.

  According to the present invention, the user can check the state of use of resources and energy in his / her home, promote the saving of resources and energy, and check the current state of housing and resident behavior, etc. It is possible to greatly improve the safety of residents in the house and the safety of automated houses.
