Technical Field

[0001] The present invention relates to a vacant house monitoring for monitoring illegal intrusion into vacant houses, abnormal energy consumption, etc. system

Background Art

[0002] In recent years, the number of vacant houses (including vacant rooms) has increased due to aging and depopulation, etc., and along with this, the risk of illegal intrusion by third parties has also increased. And, due to the increase in illegal intrusion and illegal occupation of vacant houses, there is a risk of further illegal acts and crimes, so the need to prevent and monitor illegal intrusion into vacant houses, etc. is increasing.

[0003] On the other hand, an information processing device that effectively provides information about vacant houses whose personal information cannot be specified is known (see, for example, Patent Document 1). This information processing device extracts the energy consumption per unit time over a predetermined period to determine the type of vacant house in a building, and aggregates the vacant house rate for each predetermined area to display a vacant house rate map.

Summary of the Invention

Problems to be Solved by the Invention

[0005] ​However, while the information processing device described in Patent Document 1 extracts energy consumption data to determine whether a building is vacant, it cannot monitor whether an abnormal situation has occurred, such as illegal entry by a third party or an abnormal increase in energy consumption due to a malfunction of electrical equipment (such as home appliances) installed in the vacant house. Furthermore, while it is possible to monitor whether a third party has illegally entered a vacant house by installing sensors and communication devices, installing sensors and communication devices in all vacant houses would incur enormous costs.

[0006] Therefore, the present invention provides a low-cost vacant house monitoring system that can monitor for abnormal situations such as illegal entry into vacant houses and abnormal increases in energy consumption due to malfunctions of electrical equipment installed in vacant houses. system The purpose is to provide. [Means for solving the problem]

[0007] To solve the above problems, the invention of claim 1 includes a meter installed in a vacant house that measures energy consumption at predetermined intervals, and a monitoring means that determines whether an abnormal situation has occurred in the vacant house based on the energy consumption measured at predetermined intervals by the meter in the vacant house and a predetermined determination value, and notifies a predetermined recipient if it is determined that an abnormal situation has occurred. A usage storage means for storing the amount of energy used at predetermined intervals in the past, measured in the aforementioned vacant house, Equipped with The monitoring means sets one of the following as the predetermined determination value: the energy usage from the past one year prior to the same date and time of the energy usage measured by the meter, which is the energy usage during normal times when no abnormal situation occurred; the energy usage at the same time one week prior during normal times; or the average energy usage during normal times over a predetermined period in the past. This is a vacant house monitoring system characterized by the following features.

[0009] Claim 2 The invention is characterized in that, in the vacant house monitoring system described in claim 1, the monitoring means determines that an abnormal situation requiring a simple inspection of the vacant house has occurred when the amount of energy used at predetermined intervals, measured by a meter in the vacant house, temporarily exceeds a predetermined determination value.

[0010] Claim 3The invention is characterized in that, in the vacant house monitoring system described in claim 1, the monitoring means determines that an abnormal situation requiring a detailed inspection of the vacant house has occurred when the amount of energy used at predetermined intervals, measured by a meter in the vacant house, exceeds a predetermined determination value for a predetermined period of time.

[0011] Claim 4 The invention is claimed 2 or 3 The vacant house monitoring system described above is characterized by comprising scheduling means for planning the inspection schedule of the vacant house in combination with tasks including patrol inspections related to energy supply.

[0012] Claim 5 The invention is characterized in that, in the vacant house monitoring system described in claim 1, the monitoring means determines that an abnormal situation regarding energy supply has occurred when the amount of energy used at predetermined intervals, measured by a meter in the vacant house, exceeds a predetermined abnormal value that is greater than a predetermined determination value. [Effects of the Invention]

[0019] Claim 1 According to the invention described above, it is determined whether or not an abnormal situation has occurred in a vacant house based on the amount of energy used at predetermined intervals in the vacant house and a predetermined judgment value. In other words, if the amount of energy used in a vacant house increases sharply, it is determined that an abnormal situation has occurred, as this may indicate an abnormal situation such as illegal entry or an abnormal increase in energy consumption due to a malfunction of electrical equipment installed in the vacant house. In that case, a notification is sent to a predetermined recipient, so that abnormal situations such as illegal entry into a vacant house or an abnormal increase in energy consumption due to a malfunction of electrical equipment installed in the vacant house can be properly monitored without having to go to the vacant house, and as a result, it becomes possible to quickly and appropriately confirm and respond to abnormal situations. Moreover, by monitoring and determining the amount of energy used at predetermined intervals, it becomes possible to properly and quickly monitor the occurrence of abnormal situations.

[0020] Furthermore, since energy meters that measure energy consumption at predetermined intervals are already installed and widely used, there is no need to install them specifically for monitoring vacant houses, making implementation low-cost and simple. In addition, competition has intensified in recent years in the energy industry, such as the power industry. By using this vacant house monitoring system and method to provide a service for monitoring vacant houses, power companies and other businesses that have installed meters can build closer relationships with consumers and local communities.

[0021] moreover Since the criteria for determining whether or not an abnormal situation has occurred in a vacant house are set based on the past energy usage of that vacant house, it is possible to set an appropriate value that corresponds to the actual energy usage of that vacant house. As a result, it becomes possible to accurately determine whether or not an abnormal situation has occurred in a vacant house.

[0022] Claim 2 According to the invention described, if the energy consumption in a vacant house temporarily exceeds a certain threshold, it is determined that a minor abnormality has occurred, requiring a simple inspection of the vacant house. Therefore, it becomes possible to take appropriate action according to the severity of the abnormality, that is, according to whether it is a minor abnormality.

[0023] Claim 3 According to the invention described, if the energy consumption in a vacant house continuously exceeds a predetermined value for a specified period of time, it is determined that a serious abnormality has occurred, requiring a detailed inspection of the vacant house. Therefore, it becomes possible to take appropriate action according to the degree of the abnormality, that is, according to whether it is a serious abnormality.

[0024] Claim 4 According to the invention described above, the schedule for inspecting vacant houses is planned in conjunction with tasks such as patrol inspections, making it possible to efficiently carry out regular patrol inspections and vacant house inspections.

[0025] Claim 5According to the invention described above, when the energy consumption in a vacant house exceeds an abnormal value which is a large value, it is determined that an abnormal situation has occurred regarding the energy supply. Therefore, it becomes possible to take appropriate measures corresponding to the content of the abnormal situation, that is, the abnormality of the energy supply.

Modes for Carrying Out the Invention

[0027] Hereinafter, this invention will be described based on the illustrated embodiments.

[0028] FIG. 1 is a schematic configuration diagram showing a vacant house monitoring system 1 according to an embodiment of this invention. This vacant house monitoring system 1 is a system for monitoring illegal intrusion into a vacant house H and abnormal increase in energy consumption due to failure of electrical equipment installed in the vacant house H. By monitoring the energy usage / consumption in the vacant house H, it monitors whether an abnormal situation such as an abnormal increase in energy consumption due to illegal intrusion or failure of electrical equipment has occurred.

[0029] Here, examples of the energy usage to be monitored include usage of electricity, gas, water, etc. In this embodiment, the energy usage to be monitored is the electricity usage, and the case where the power company C provides the vacant house monitoring service by the vacant house monitoring system 1 will be described. In contrast, other energy usages may be monitored, or other companies may provide the vacant house monitoring service.

[0030] Furthermore, the term "vacant house H" in this invention includes not only "houses that have not been lived in or used for more than one year" as defined in the Special Measures Act on Countermeasures against Vacant Houses, but also houses where residents are absent for a short period (for example, several months), as well as vacant rooms in rental apartments and condominiums. In other words, it includes all houses and rooms that are not currently inhabited, regardless of the length of time or type of residence, and for which the user wishes to receive the vacant house monitoring service. Therefore, the user U who receives the vacant house monitoring service can be anyone, including, for example, the owner of a house that has not been lived in for a long period, a resident who is temporarily absent from the house, a house manager / real estate company, or the owner of an apartment or condominium with vacant rooms.

[0031] The vacant house monitoring system 1 mainly comprises smart meters (meters) 2 installed in each vacant house H, a smart meter operation management server (usage data storage means) 3, and a monitoring server (monitoring means) 4. Each smart meter 2 and smart meter operation management server 3, and the smart meter operation management server 3 and the monitoring server 4 are connected to each other via communication.

[0032] Smart Meter 2 is installed in all customer homes (including vacant houses H) that receive electricity from power company C. It measures the amount of electricity used in each customer home at predetermined intervals and has the same configuration as off-the-shelf smart meters. Specifically, it measures electricity usage every 30 minutes and transmits the measurement data (30-minute data) and meter number to the smart meter operation management server 3 in real time. Therefore, 48 30-minute data points are transmitted to the smart meter operation management server 3 per day.

[0033] The smart meter operation management server 3 is a server that constructs a smart meter operation management system for operating and managing each smart meter 2. It receives 30-minute value data from each smart meter 2 and stores the 30-minute value data in chronological order for each smart meter 2's meter number. In other words, it stores the past energy usage measured at each vacant house H for predetermined time intervals.

[0034] The monitoring server 4 is a server that monitors whether or not an abnormal situation has occurred in vacant house H based on the energy usage and consumption of vacant house H. As shown in Figure 2, it mainly comprises an input unit 41, a communication unit 42, a vacant house database 43, a work plan database 44, a monitoring task (monitoring means) 45, a scheduling task (scheduling means) 46, and a central processing unit 47 that controls these.

[0035] The input unit 41 is an interface for inputting various information and commands, specifically for inputting data into the vacant house database 43 and inputting commands to start monitoring tasks 45. The communication unit 42 is an interface for communicating with the outside world, mainly for communicating with the user communication terminal 5 of user U and the inspector communication terminal 6 of inspector W, etc.

[0036] The vacant house database 43 is a database that stores information about vacant houses H, and as shown in Figure 3, for each contract number 431, it stores the name 432, address 433, contact information 434, instrument 435, judgment value 436, and inspection 437, etc.

[0037] Contract number 431 stores identification information and a contract number that identifies the contract between the power company and user U regarding the vacant house monitoring service, and name 432 stores user U's name. Address 433 stores the address of vacant house H to be monitored as requested by user U, and room number etc. if necessary, and contact information 434 stores information for contacting user U, in particular an email address and telephone number for sending abnormality notifications and inspection result notifications, which will be described later.

[0038] Meter 435 stores the meter number of the smart meter 2 installed in the vacant house H being monitored, and judgment value 436 stores the judgment value / threshold (30-minute value data) that serves as the judgment criterion in monitoring task 45. If prior consultation has taken place between the power company and user U, this judgment value is the value set in the consultation; if no prior consultation has taken place, it is the value set in monitoring task 45, as described later. Furthermore, there may be more than one judgment value. For example, there may be a value set for each time of day, or a value set according to the season.

[0039] Inspection 437 stores whether user U wishes (requests) an inspection of vacant house H if the monitoring task 45, described later, determines that an abnormal situation has occurred in vacant house H. Specifically, it stores whether user U wishes to have a simple inspection, described later, or a detailed inspection, described later.

[0040] The work plan database 44 is a database that stores schedules and dates related to tasks, including inspections of electricity supply. Specifically, it stores when and where inspections of power facilities and construction work, which involve visits and travel, will be performed. These dates are retrieved and stored from the work plan server, which plans and formulates the schedules for inspections and construction work. In addition, the inspection schedule for vacant house H, which was planned in the scheduling task 46 as described later, is also stored. Here, it is also possible to read and store information directly from the work plan server without creating a work plan database 44.

[0041] The monitoring task 45 is a task program for determining whether an abnormal situation has occurred in vacant house H based on the amount of electricity used at predetermined intervals measured by the smart meter 2 of vacant house H and a predetermined judgment value. In this embodiment, it is activated each time 30-minute data is received from the smart meter 2 of vacant house H via the smart meter operation management server 3. That is, it is activated each time the amount of electricity used in vacant house H is measured at predetermined intervals or every 30 minutes, but it may be activated once a day or several times a day to determine whether an abnormal situation has occurred for each 30-minute data, as will be described later.

[0042] When activated, the system first searches the vacant house database 43 for information about vacant house H whose meter number matches the meter number received along with the 30-minute value data for vacant house H, and whose meter number is stored in meter 435. Then, it compares the judgment value stored in judgment value 436 of the acquired information with the received 30-minute value data for vacant house H (target 30-minute value data). At this time, if a judgment value is stored in judgment value 436, this value is used; otherwise, the judgment value is set as follows.

[0043] In other words, the determination value is set based on past 30-minute data of the vacant house H stored in the smart meter operation management server 3. For example, if 30-minute data for the vacant house H from one year ago at the same date and time as the target 30-minute data (data from normal times when no abnormal situation occurred) is stored, this 30-minute data is set as the determination value. Alternatively, if 30-minute data from the same time during normal times one week prior is stored, this 30-minute data is set as the determination value. In addition, the average 30-minute data from a predetermined past period (for example, the past week) may be set as the determination value.

[0044] If the target 30-minute data exceeds the threshold value, it is determined that an abnormal situation has occurred. This determination is repeated for the target 30-minute data over a predetermined period (for example, one day), and if the target 30-minute data temporarily exceeds the threshold value, it is determined that an abnormal situation requiring a simple inspection of vacant house H has occurred. Furthermore, if the target 30-minute data continues to exceed the threshold value for a predetermined period of time, it is determined that an abnormal situation requiring a detailed inspection of vacant house H has occurred.

[0045] Here, an abnormal situation requiring a simple inspection of vacant house H (such as an external inspection) refers to a temporary, minor abnormal situation such as a burglary or temporary theft of electricity, while an abnormal situation requiring a detailed inspection of vacant house H (such as an internal inspection) refers to a continuous, serious abnormal situation such as illegal occupation or stay in vacant house H or prolonged, long-term theft of electricity. Furthermore, a temporary exceedance refers to a situation where one or more 30-minute data points exceed the limit either sporadically or consecutively. In addition, the predetermined time for determining whether the limit has been exceeded for a continuous period may be set individually in consultation with user U, or it may be set based on the form of a continuous abnormal situation that has occurred in the past (e.g., illegal occupation) and its duration (e.g., duration of illegal occupation).

[0046] Furthermore, if the target 30-minute data exceeds a predetermined abnormal value that is larger than the judgment value mentioned above, it is determined that an abnormal situation related to the supply of electricity has occurred. In other words, if the target 30-minute data is a large value that would not occur in abnormal situations such as burglary, illegal occupation, or electricity theft as described above, it is determined that an abnormal situation related to the supply of electricity, such as a ground fault or short circuit, has occurred. Here, the predetermined abnormal value is set based on 30-minute data from past ground faults and short circuits.

[0047] If it is determined that an abnormal situation has occurred, the system will notify a designated recipient of the abnormal situation. Specifically, in this embodiment, an abnormality notification is sent to an email address stored in the contact information 434 of the vacant house H (meter 435), as well as to the administrator of the vacant house monitoring service. The abnormality notification includes the name of the user U of the vacant house H, the address of the vacant house H, and the type of abnormal situation, such as whether an abnormal situation requiring a simple inspection of the vacant house H has occurred, whether an abnormal situation requiring a detailed inspection of the vacant house H has occurred, or whether an abnormal situation related to the supply of electricity has occurred.

[0048] Next, based on the information from inspection 437, it is determined whether user U of vacant house H, where an abnormal situation has been determined to have occurred, wishes to have an inspection. If it is determined that an abnormal situation requiring a simple inspection has occurred, and user U wishes to have a simple inspection, vacant house H will be subject to a simple inspection. If it is determined that an abnormal situation requiring a detailed inspection has occurred, and user U wishes to have a detailed inspection, vacant house H will be subject to a detailed inspection. Furthermore, if it is determined that an abnormal situation related to the supply of electricity has occurred, vacant house H will be subject to an equipment inspection. The information of these vacant houses H subject to inspection is then stored in memory.

[0049] The scheduling task 46 is a task program that plans the inspection schedule for vacant houses H in combination with tasks including patrol inspections related to the supply of electricity. Specifically, the central processing unit 47 periodically checks (for example, once a day, once a week, once a month) whether there are any vacant houses H that are subject to inspection as described above. If there are vacant houses H that are subject to inspection, the scheduling task 46 is activated and the inspection schedule is planned.

[0050] Specifically, the inspection of vacant house H is planned to be carried out efficiently based on the schedules of patrol inspections and construction work stored in the work plan database 44. For example, if a patrol inspection is scheduled around vacant house H that is subject to a simple inspection or a detailed inspection, vacant house H is incorporated into the schedule of that patrol inspection. Also, if construction work is scheduled around vacant house H that is subject to an equipment inspection, vacant house H is incorporated into the schedule of that construction work. The inspection schedule for vacant house H, planned in this way, is then stored in the work plan database 44.

[0051] Next, the operation, function, and method of monitoring vacant houses using the vacant house monitoring system 1, as configured in this way, will be explained based on the timing chart in Figure 4.

[0052] First, when the electricity usage of each vacant house H is measured every 30 minutes by the smart meter 2, the 30-minute value data is transmitted to the smart meter operation management server 3 (step S1) and stored. Next, the monitoring task 45 is activated (step S2), and as described above, it is determined whether or not an abnormal situation has occurred at the vacant house H based on the 30-minute value data and the judgment value. At this time, as described above, if the 30-minute value data temporarily exceeds the judgment value, it is determined that an abnormal situation requiring a simple inspection of the vacant house H has occurred; if the 30-minute value data continues to exceed the judgment value for a predetermined time, it is determined that an abnormal situation requiring a detailed inspection of the vacant house H has occurred; and if the 30-minute value data exceeds the abnormal value, it is determined that an abnormal situation related to the supply of electricity has occurred.

[0053] As a result, if it is determined that an abnormal situation has occurred (if the answer is "Y" in step S3), an abnormality notification is sent to the user communication terminal 5 of user U of vacant house H, the administrator, etc. (step S4). Next, it is checked whether there is a vacant house H that is subject to periodic inspection (step S5), and if there is a vacant house H subject to inspection (if the answer is "Y"), the scheduling task 46 is activated (step S6), and as described above, an inspection schedule is planned in combination with tasks such as patrol inspections. Then, inspectors W, etc., inspect vacant house H according to the plan (step S7).

[0054] In this process, for vacant houses H that are subject to a simple inspection, only the exterior of vacant house H is inspected to check for any abnormalities. For vacant houses H that are subject to a detailed inspection, not only the exterior of vacant house H is inspected, but the interior of vacant house H is also carefully inspected to check for any abnormalities. Furthermore, for vacant houses H that are subject to an equipment inspection, equipment such as a tester is used to check for any leakage current or short circuits. When the inspector W or other person sends the inspection results to the monitoring server 4 using the inspector communication terminal 6, an inspection result notification is sent from the monitoring server 4 to the user communication terminal 5 of user U (step S8).

[0055] As described above, this vacant house monitoring system 1 and vacant house monitoring method automatically determine whether an abnormal situation has occurred in vacant house H based on the amount of electricity used at predetermined intervals and a predetermined judgment value. In other words, if the amount of electricity used at vacant house H increases sharply, it is automatically determined that an abnormal situation has occurred, as this may indicate an abnormal situation such as illegal entry or an abnormal increase in energy consumption due to a malfunction of electrical equipment installed in vacant house H. In that case, an automatic notification is sent to a predetermined recipient, so it is possible to properly monitor for illegal entry into vacant house H, an abnormal increase in energy consumption due to a malfunction of electrical equipment, or if user U has temporarily entered vacant house H and left the power on after using electrical equipment, without having to go to vacant house H. As a result, it becomes possible to quickly and appropriately confirm and respond to abnormal situations. Moreover, by monitoring and determining the amount of electricity used at predetermined intervals, it is possible to properly and quickly monitor for the occurrence of abnormal situations.

[0056] Furthermore, since smart meters 2, which measure electricity usage at predetermined intervals, are already installed and widely used, there is no need to install them specifically for monitoring vacant houses H, making implementation low-cost and easy. In addition, competition in the electricity industry has intensified in recent years, and by providing a vacant house monitoring service, electricity provider C, which has installed smart meters 2, can build closer relationships with consumers and the local community.

[0057] Furthermore, since the criteria for determining whether or not an abnormal situation has occurred in each vacant house H are set based on the past electricity usage of each vacant house H, it is possible to set an appropriate value according to the actual electricity usage of that vacant house H. As a result, it becomes possible to accurately determine whether or not an abnormal situation has occurred in a vacant house H.

[0058] Furthermore, if the electricity usage in vacant house H temporarily exceeds the threshold, it will be determined that a minor abnormality has occurred, requiring a simple inspection of vacant house H. This makes it possible to take appropriate action according to the severity of the abnormality, i.e., a minor abnormality.

[0059] Furthermore, if the electricity consumption at vacant house H exceeds the specified threshold for a predetermined period of time, it is determined that a serious abnormality has occurred, requiring a detailed inspection of vacant house H. This makes it possible to take appropriate action according to the severity of the abnormality, i.e., whether it is a serious abnormality.

[0060] Furthermore, since the inspection schedule for vacant house H is planned in conjunction with other tasks such as patrol inspections, it becomes possible to efficiently carry out both regular patrol inspections and the inspection of vacant house H.

[0061] Furthermore, if the amount of electricity used in vacant house H exceeds a large, abnormal value, it is determined that an abnormal situation regarding the electricity supply has occurred. This makes it possible to take appropriate action according to the nature of the abnormal situation, that is, the abnormality in the electricity supply.

[0062] Although embodiments of this invention have been described in detail above, the specific configuration is not limited to these embodiments, and any design changes, etc., that do not depart from the gist of this invention are also included. For example, in the above embodiment, the case in which the smart meter operation management server 3 is the usage amount storage means was described, but the storage unit constituting the usage amount storage means may be provided in the monitoring server 4.
