In recent years, stalking damage has been on the rise. The majority of victims of this stalker are women living alone in their twenties and thirties, but the economic power of these young women is generally low. On the other hand, in the suspicious person intrusion detection service provided by a security company, it is necessary to install a motion sensor, a carbon dioxide detection sensor, a special sensor such as a surveillance camera, a camera, etc., and the price for receiving the service is high. As a result, for example, for women living alone, there was a high hurdle to using security services even if they were worried about crime prevention.

An object of the present invention is to provide a system and an estimation method for estimating the intrusion or sitting of another person when the person is absent from home without using a special sensor or camera.

The present invention that achieves the above object is an absentee information acquisition means for acquiring absentee information, which is information indicating that the resident is absent, and resources in the resident's living space when the absentee information is acquired. It is provided with an absentee consumption information acquisition means for acquiring the absentee consumption information which is information on the consumption state of the resident, and an estimation means for estimating the existence of an intruder in the absence of a resident from the acquired absentee consumption information. It is a security system characterized by this.
More specifically, the absentee information acquired by the absentee information acquisition means is information based on the existence position of the resident or information based on the actions of the resident. In addition, the absentee consumption information is the state of resource consumption due to the operation of a specific facility.
More preferably, the above security system further includes a notification means for notifying the estimation result to the outside when the existence of an intruder is estimated.
In addition, another invention that achieves the above object acquires information on the consumption state of resources in the living space of the resident, recognizes when the resident does not exist in the living space, and resides. Forcibly consume the resources of the living space by detecting the occurrence of an event indicating the possibility that a person exists when the person is absent, and estimate the existence of an intruder based on the resource consumption state when the person is absent. It is an intruder estimation method characterized by.
Yet another invention that achieves the above object is to provide the mobile computer with a function of recognizing that the owner of the mobile computer is absent in a place other than the owner's living space, and other places. It is a program that realizes a function to acquire the absentee consumption information regarding the resource consumption state in the living space when the person is in the office and a function to output the acquired absentee consumption information.

According to the present invention, it is possible to more easily estimate the intrusion or sitting of another person when he / she is away from home, as compared with the case where only a special sensor, a camera, or the like is installed to detect the intrusion or sitting.

It is a figure which shows the whole structure of the security system by this embodiment. It is a figure which shows the example of the notification screen at the time of immediately notifying the received analysis result. FIG. 3A is a diagram showing an example of a notification screen when the analysis result is notified according to the operation of the terminal device by the resident, and FIG. 3A is a diagram showing an example of the notification screen when it is estimated that an intruder exists. , FIG. 3B is a diagram showing an example of a notification screen when it is estimated that there is no intruder. It is a figure which shows the configuration example of the security system which notifies the analysis result when a resident returns to the vicinity of a residence. It is a figure which shows the configuration example of the security system which estimates the existence of an intruder by forcibly consuming resources. It is a flowchart which shows the operation of the security system shown in FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
<System configuration>
FIG. 1 is a diagram showing an overall configuration of a security system according to the present embodiment. The security system 100 includes an instrument 110, an information processing device 120, and a terminal device 130. The instrument 110 and the terminal device 130 can exchange data with the information processing device 120 via a network, respectively.

The instrument 110 is a device that measures the amount of various resources used in daily life in a living space such as a house. Here, examples of resources used in daily life include energy resources such as electricity and gas, and water resources such as water supply. That is, as the instrument 110, specifically, an electric meter, a gas meter, a water meter, or the like set in the building is used. The number of instruments 110 used in the security system 100 is not particularly limited. In the example shown in FIG. 1, three instruments 110 are shown, but only one or two instruments 110 may be provided, or four or more instruments 110 may be provided. In the present embodiment, in order to detect that the resource in the living space has been used when the resident is absent and estimate the intruder, a plurality of instruments 110 for detecting the consumption of different types of resources are provided. Therefore, it is expected that the estimation accuracy can be improved.

The instrument 110 includes a transmission unit 111 and a storage unit 112. The transmission unit 111 transmits the measurement data by the instrument 110 to the information processing device 120. As the transmission unit 111, for example, a wireless or wired network interface or the like is used. The storage unit 112 stores the measurement data by the instrument 110. By storing the measurement data in the storage unit 112, the measurement data can be periodically transmitted together to some extent instead of being constantly transmitted by the transmission unit 111. As the storage unit 112, for example, a semiconductor memory or the like is used. A relay device (not shown) that collects and accumulates the measurement data of the plurality of instruments 110 and collectively transmits the measurement data to the information processing device 120 may be provided separately. In this case, the storage unit 112 is not an indispensable configuration, and the instrument 110 may be configured to immediately transmit the measurement data to the relay device by the transmission unit 111.

The information processing device 120 is a device that monitors (monitors) the presence or absence of an intruder when a resident (user of the security system 100) is absent in a living space such as a residence. Specifically, when the information processing device 120 estimates whether or not an intruder exists in the residence based on the resource consumption information when the resident is absent in the living space, and estimates that the intruder exists. , A device that notifies the resident's terminal 130. The information processing device 120 includes an absence information acquisition unit 121, a consumption information acquisition unit 122, an information analysis unit 123, and a transmission / reception unit 124. The information processing device 120 may be realized by a computer arranged in a living space or the like, or may be realized by a server provided on a network. Further, it is not necessary to configure a single computer, and each function of the information processing device 120 may be distributed by a plurality of servers, and some or all of the functions of the information processing device 120 are provided in a so-called cloud environment. It may be realized by doing.

The absence information acquisition unit 121 acquires the set absence information. Absence information is information set to recognize that the resident is absent. As the absence information, for example, information based on the location of the resident, information based on the actions of the resident, and the like are used. The absence information acquisition unit 121 is an example of the absence information acquisition means.

Information based on the location of the resident will be explained. If it is identified that the resident is in a place different from the residence based on the information indicating the location of the resident, it can be recognized that the resident is absent. That is, the information on the existence position of the resident indicating a place different from the residence becomes the absence information based on the existence position of the resident. Here, the existence position of the resident is fictitious by, for example, the position of the terminal device 130 possessed by the resident. As the information indicating the existing position (of the terminal device 130) of the resident, the position information of the terminal device 130 specified by a satellite positioning system (Navigation Satellite System) such as GPS (Global Positioning System) may be used. Further, the location information of the Wi-Fi (registered trademark) access point or the base station of the mobile phone to which the terminal device 130 is connected may be used.

Explain information based on the actions of residents. It is possible to recognize that the resident is absent if the act to be performed when the resident goes out or while going out is specified and it is detected that such a specific act has been performed. That is, the detection information of such a specific act becomes the absence information based on the act of the resident. Here, the act of the resident may be an intentional act or an unconscious act. For example, it may be an act such as going out registration performed by the resident manually, or the absence information may be automatically acquired in conjunction with the action performed by the resident when going out. In the former case, for example, the terminal device 130 displays the registration screen for outing registration, the registration screen accepts the operation of the outing registration by the resident, and the terminal device 130 transmits the operation information to the information processing device 120, and the absence information It is conceivable that the acquisition unit 121 acquires the operation information as absence information. Further, in the latter case, for example, when the electronic lock of the entrance door is locked from the outside, a signal may be transmitted from the electronic lock to the information processing device 120, and the absence information acquisition unit 121 may acquire the received signal as absence information. I can think of it.

The consumption information acquisition unit 122 acquires resource consumption information from the instrument 110. The resource consumption information may be the measurement data itself measured by the instrument 110, or may be processed information (for example, total consumption for a certain period of time). The consumption information acquisition unit 122 acquires consumption information indicating that resources such as electricity, gas, and water (resources used in daily life) have been consumed due to the use of electrical equipment, gas equipment, water supply equipment, and the like. The consumption information acquisition unit 122 is an example of an absent consumption information acquisition means. However, the consumption information acquired by the consumption information acquisition unit 122 is not limited to the consumption information when the resident is absent. That is, the consumption information acquisition unit 122 acquires consumption information regardless of the presence or absence of the resident, and the consumption information acquired after the absence information acquisition unit 121 acquires the absence information is the consumption information when the resident is absent ( The following is information on consumption during absence).

The information analysis unit 123 analyzes the absentee consumption information and estimates whether or not there is an intruder in the house. The information analysis unit 123 is an example of the estimation means. Specifically, the information analysis unit 123 first recognizes the absence of a resident in the residence based on the absence information acquired by the absence information acquisition unit 121. Then, the information analysis unit 123 analyzes the consumption information (absent consumption information) acquired by the consumption information acquisition unit 122 to specify the resource consumption state. Then, the information analysis unit 123 determines the operating state (whether or not the equipment has been operated) of the specific equipment based on the consumption state of the specified resource. Then, when the information analysis unit 123 detects the operation of a specific facility, the information analysis unit 123 notifies the terminal device 130 that there is a possibility that an intruder exists in the house.

Here, the operation of a specific facility is an operation caused by a person using the facility. For example, it can be used for cleaning toilet bowls, using lighting and electrical equipment, and using gas appliances (stove, water heater, etc.). The resource to be detected may be selectable by setting. For example, when only the use of electricity and the use of water are set as detection targets, even if the gas appliance operates, it is not detected as an operation based on the absentee consumption information. Further, if the equipment used can be identified from the resource consumption amount and the consumption pattern, the detection target may be set for each equipment and its operating state. For example, when electricity consumption due to the use of lighting is set as a detection target among electric devices, even if the air conditioner operates, it is not detected as an operation based on the absence consumption information. Various patterns can be considered for the resource consumption state in which it is judged that a person has used the equipment, depending on the type of resource and the like. For example, the cumulative usage of gas and water resources increased, the power consumption of electricity was more than twice the normal minimum power consumption, and there was a change from the normal power consumption when absent. It is conceivable that when these consumption patterns are detected, it may be determined that the resources have been consumed due to the use of the equipment by a person.

The information analysis unit 123 excludes the consumption of resources in a specific facility from the detection target due to a cause other than the operation caused by the use of the facility by a person. Examples of such resource consumption include resource consumption that occurs even when the standby voltage of electrical equipment is absent, resource consumption by equipment that the resident forgets to stop when going out, and resource consumption by equipment that operates by setting a timer. Be done. Resource consumption that occurs even when absent, and resource consumption by equipment that has forgotten to stop can be identified based on, for example, resource consumption or consumption pattern. Specifically, it can be identified based on a consumption pattern such as constant consumption for a certain period of time after the absence information is acquired. Further, the resource consumption by the equipment operated by the timer setting can be identified by acquiring the timer setting information from the control device of the equipment and determining whether or not the consumption is at the specified time based on the timer setting information.

Each function of the absence information acquisition unit 121, the consumption information acquisition unit 122, and the information analysis unit 123 is realized, for example, by the CPU (Central Processing Unit) reading and executing the program.

The transmission / reception unit 124 is a network interface, connects to the instrument 110 and the terminal device 130 via the network, and exchanges data. That is, the transmission / reception unit 124 receives the consumption information from the instrument 110 and sends it to the consumption information acquisition unit 122. Further, the transmission / reception unit 124 receives the absence information set from the terminal device 130 and other absence information transmission means and sends it to the absence information acquisition unit 121. Further, the transmission / reception unit 124 transmits the analysis result by the information analysis unit 123 to the terminal device 130. The transmission / reception unit 124 is an example of notification means.

The terminal device 130 is a device that receives a notification from the information processing device 120 regarding the presence or absence of an intruder and notifies a resident who is a user. The terminal device 130 is realized by a mobile computer that a resident who is a user can carry when going out. For example, a smartphone, a mobile phone, a tablet-type personal computer, a notebook-type personal computer, a wearable-type personal computer, or the like can be used as the terminal device 130. Further, as the terminal device 130, a dedicated terminal device for receiving a notification from the information processing device 120 and notifying the information processing device 120 may be provided. The terminal device 130 includes a transmission / reception unit 131, a display unit 132, an operation reception unit 133, and a control unit 134.

The transmission / reception unit 131 connects to the information processing device 120 via a network and exchanges data. That is, the transmission / reception unit 131 receives the analysis result (estimation result of the presence / absence of an intruder) of the absentee consumption information from the information processing device 120. Further, when the information based on the action of the resident is used as the absence information and the operation of the outing registration in the terminal device 130 is set as the action of the resident, the transmission / reception unit 131 indicates that the outing registration has been performed. The indicated information is transmitted to the information processing device 120. The transmission / reception unit 131 is realized by, for example, a communication device that connects to a mobile phone line or a network line to perform data communication.

The display unit 132 displays a notification screen for notifying the resident who is the user of the analysis result of the absentee consumption information received from the information processing device 120 and an operation screen for performing various operations. The display unit 132 is composed of, for example, a liquid crystal display.

The operation receiving unit 133 receives the operation of the resident who is the user. The operation receiving unit 133 is composed of, for example, a touch sensor that outputs a control signal according to a position touched or pressed by a finger. A user interface is composed of a touch panel that combines a touch sensor and a liquid crystal display constituting the display unit 132.

The control unit 134 controls the operation based on each function of the terminal device 130. The control unit 134 includes, for example, a CPU, a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU reads the program stored in the ROM and executes the program using the RAM as a work area to perform various controls and data processing.

<Notification of analysis results>
When the terminal device 130 receives the analysis result (estimation result of presence / absence of intruder) of the absence information by the information processing device 120, the terminal device 130 displays a notification screen on the display unit 132 and displays the analysis result to the resident who is the user. Notify. Various methods can be used as the notification method, but as an example, when it is estimated that an intruder exists based on the analysis result, it is conceivable to immediately notify the analysis result. Further, as another example, it is conceivable to operate the terminal device 130 at a timing desired by the resident, such as when returning home, receive such an operation, receive the analysis result from the information processing device 120, and notify the information processing device 120.

FIG. 2 is a diagram showing an example of a notification screen when the received analysis result is immediately notified. A message area 132a and a button object 132b are displayed on the notification screen of this display example displayed on the display unit 132 of the terminal device 130. In the message area 132a, the characters "warning" that calls the attention of the resident and the message "Is there an intruder to report?" Is displayed indicating the analysis result. On the button object 132b, the button name "report" is displayed. The button object 132b is linked to a function of reporting to a reporting destination (hereinafter referred to as a reporting function) via a mobile phone line or a network line. Then, when the button object 132b is selected by the resident, the notification function is called to automatically notify the preset notification destination. For example, the police, security company, management company, etc. may be set as the report destination.

FIG. 3 is a diagram showing an example of a notification screen when the analysis result is notified according to the operation of the terminal device 130 by the resident. FIG. 3A shows an example of a notification screen when it is estimated that an intruder exists, and FIG. 3B shows an example of a notification screen when it is estimated that an intruder does not exist.

In the example shown in FIG. 3A, the message area 132c and the button object 132d are displayed on the notification screen displayed on the display unit 132. In the message area 132c, the message "Do you want to report an intruder?" Is displayed, which indicates the analysis result. The button name "report" is displayed on the button object 132d. The button object 132d is linked to the reporting function in the same manner as the button object 132b shown in FIG. Then, when the button object 132d is selected by the resident, the notification function is called to automatically notify the preset notification destination.

In the example shown in FIG. 3B, the message area 132e and the button object 132f are displayed on the notification screen displayed on the display unit 132. In the message area 132e, the message "No abnormality" indicating the analysis result is displayed. On the button object 132f, the button name "release watch" is displayed. The button object 132f is linked to a function of canceling the monitoring of resource consumption due to the operation of the specific equipment when the information processing device 120 is absent. Then, when the button object 132f is selected by the resident, the release function is called to release the monitoring of resource consumption by the information processing device 120.

<First modification>
In the above embodiment, the information processing device 120 is provided on the network, and the information processing device 120 estimates the presence or absence of an intruder in the absence of a resident based on the consumption information received from the instrument 110, and estimates the result as a terminal device. Notified 130. Therefore, in the above notification example, an example of immediately notifying the analysis result received from the information processing device 120 and an example of notifying the analysis result according to the operation of the terminal device 130 by the resident have been described. On the other hand, it is conceivable to notify the analysis result immediately before the resident returns home (before entering the residence) and when the resident returns near the residence.

FIG. 4 is a diagram showing a configuration example of a security system 100 that notifies an analysis result when a resident returns near the residence. In the configuration shown in FIG. 4, the instrument 110, the information processing device 120, and the terminal device 130 are the same as the devices shown in FIG. That is, in the configuration example shown in FIG. 4, the intruder notification device 140 is added to the security system 100 shown in FIG. The transmission / reception unit 124 (see FIG. 1) of the information processing device 120 transmits the analysis result of the information analysis unit 123 to the intruder notification device 140 in addition to or in place of the terminal device 130. Further, the transmission / reception unit 131 of the terminal device 130 has a function of exchanging data with the intruder notification device 140.

The intruder notification device 140 is installed in a residential building or the like, and acquires and holds the analysis result by the information processing device 120. Then, when it is detected that the resident has approached a range of a certain distance from the residence, the holding analysis result is transmitted to the terminal device 130. The intruder notification device 140 includes a receiving unit 141, a storage unit 142, and a short-range wireless communication unit 143.

The receiving unit 141 connects to the information processing device 120 via the network, and receives the analysis result (estimation result of the presence or absence of an intruder) of the absentee consumption information. As the receiving unit 141, for example, a wireless or wired network interface or the like is used. The storage unit 142 stores the analysis result received by the reception unit 141. As the storage unit 142, for example, a semiconductor memory or the like is used.

By providing the intruder notification device 140 configured in this way, when the resident approaches the residence when returning home, the resident receives the communication from the intruder notification device 140 at the terminal device 130 and the analysis result by the information processing device 120. Is received, and the presence or absence of an intruder can be confirmed on the notification screen displayed on the terminal device 130. As the notification screen, for example, the screens illustrated in FIGS. 3A and 3B may be used.

<Second modification>
The security system 100 of the present embodiment detects the consumption of resources used in daily life in a residence where no resident is present and estimates the existence of an intruder. That is, the premise of estimation is that an intruder operates a specific facility in a house and consumes resources. On the other hand, intruders may not operate the facilities of the residence. Therefore, when there is a possibility that an intruder exists, it is conceivable to automatically operate the equipment to forcibly consume resources, detect the consumption of such resources, and estimate the existence of the intruder.

FIG. 5 is a diagram showing a configuration example of a security system 100 that forcibly consumes resources and estimates the existence of an intruder. In the configuration shown in FIG. 5, the instrument 110, the information processing device 120, and the terminal device 130 are the same as the devices shown in FIG. That is, in the configuration example shown in FIG. 5, the operating device 150 is added to the security system 100 shown in FIG. The transmission / reception unit 124 (see FIG. 1) of the information processing device 120 transmits the absence information acquired by the absence information acquisition unit 121 to the operating device 150. Further, when the resource to be analyzed is set in the information processing device 120, the setting information is transmitted to the operating device 150.

The operating device 150 is installed in a residential building or the like, and when a specific operating condition is satisfied, the equipment set as an operating target is operated by remote control to forcibly consume resources. By forcibly consuming resources, in the information processing device 120, the information analysis unit 123 recognizes the operation of the equipment and notifies the terminal device 130 that there is a possibility that an intruder exists. The operating device 150 includes a transmission / reception unit 151, an absence information acquisition unit 152, an event detection information acquisition unit 153, and an operation unit 154.

The transmission / reception unit 151 connects to the information processing device 120 via a network to exchange data, and receives absent information and information on equipment set as an analysis target. In addition, the transmission / reception unit 151 receives detection information from a sensor that detects an event described later. In addition, the transmission / reception unit 151 transmits a control signal for operating the equipment to be operated. As the transmission / reception unit 151, for example, a wireless or wired network interface, a wireless device, or the like is used.

The absence information acquisition unit 152 receives the absence information received from the information processing device 120 by the transmission / reception unit 151. The operation device 150 starts the operation control of the equipment on the condition that the absence information acquisition unit 152 receives the absence information.

The event detection information acquisition unit 153 indicates that the occurrence of an event indicating the possibility of intrusion (the possibility of the existence of a person) of another person (a person other than the resident) is detected when the resident is absent. To get. As described above, the absence of a resident is specified by the absence information acquisition unit 152 acquiring the absence information. An event that indicates the possibility of another person's invasion is an event that occurs due to an action that is considered to be taken when a person invades the living space. For example, opening and closing of the entrance door, opening and closing of the window, unlocking of the entrance and the window, etc. can be considered, and are selected in advance by setting. Further, the event may be set in combination with the operation of the intercom. For example, when the entrance door is unlocked from the outside after the intercom is operated. These events can be detected by a simple sensor without using an advanced sensor or a surveillance camera for detecting the intrusion of a person. Therefore, it is considered that it can be introduced economically with a small burden.

The operation unit 154 remotely controls the equipment in the living space set as the operation target on the condition that the absence information is acquired by the absence information acquisition unit 152 and the event detection information is acquired by the event detection information acquisition unit 153. To operate. The operation unit 154 has a function of a remote control device (remote controller) for the equipment to be operated.

Each function of the absence information acquisition unit 152, the event detection information acquisition unit 153, and the operation unit 154 is realized, for example, by the CPU provided in the operating device 150 reading and executing the program recorded in the ROM.

FIG. 6 is a flowchart showing the operation of the security system 100 shown in FIG. When the absence information is acquired in the information processing device 120, the information processing device 120 starts monitoring the amount of resources used, and the information processing device 120 sends the absence information to the operating device 150. When the absence information acquisition unit 152 acquires the absence information, the resident is absent (when the resident is absent is recognized) (YES in S601), so that the operation control of the equipment by the operation device 150 is started.

When the event detection information acquisition unit 153 acquires the event detection information by the signal transmitted from the sensor and the event set in the operating device 150 is detected (YES in S602), the operation unit 154 is set as the operation target. The specific equipment is operated and resources are forcibly consumed (S603). Information indicating the consumption of such resources is acquired by the consumption information acquisition unit 122 in the information processing device 120, analysis of resource consumption is performed by the information analysis unit 123, and the analysis result (intrusion) from the information processing device 120 to the terminal device 130. (Estimation result of presence / absence of person) is transmitted (S604).

Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above embodiments. For example, in the above embodiment, the information processing device 120 and the terminal device 130 are provided separately, but the functions of the information processing device 120 are configured by software and provided as an application program, and the information processing device 120 is installed in the terminal device 130. You may use it. In this case, the information processing device 120 and the terminal device 130 are realized by common hardware. Further, in the above embodiment, the information processing device 120 transmits the result of analyzing the resource consumption information (estimation result of the presence or absence of an intruder) to the terminal device 130, but for example, the consumption information is transmitted to the information processing device at regular time intervals. It may be transmitted from 120 to the terminal device 130, and the terminal device 130 may indicate the change in the resource consumption state by a numerical value or a graph. Further, in the present embodiment, the presence of an intruder is estimated by detecting the consumption of resources used in daily life without using an advanced sensor or a surveillance camera that detects the intrusion of a person into the living space. However, the present embodiment may be applied in combination with monitoring by such an advanced sensor or a surveillance camera. In addition, various changes and alternative configurations that do not deviate from the scope of the technical idea of the present invention are included in the present invention.
