(1) Overview Hereinafter, an overview of the security system 100 according to the embodiment will be described with reference to FIGS. 1 and 2. The security system 100 according to the present embodiment is a system for monitoring the state of a building B1 such as a detached house, for example, and includes a mobile terminal 1 and a monitoring system 2. The portable terminal 1 can communicate with the monitoring system 2 wirelessly via a base station BS1 provided by a communication carrier and a network N1 such as the Internet. The monitoring system 2 is configured to monitor the state of the building B1 in the specific area A1. In the present embodiment, the specific area A1 is a site of the building B1 including the building B1.

The mobile terminal 1 includes a detection unit 11, a positioning unit 12, a control unit 13, and a communication unit 14. The detection unit 11 is configured to detect the state of the mobile terminal 1. The state of the mobile terminal 1 includes not only the state of the mobile terminal 1 itself but also the state of the user who owns the mobile terminal 1. The positioning unit 12 is activated in accordance with the detection result of the detection unit 11, measures the position information of the portable terminal 1 using a positioning system including the positioning satellite S1, and stops after the measurement.

The control unit 13 is configured to execute a determination process. Whether or not the mobile terminal 1 exists in the specific area A1 is determined based on the relative relationship between the position information of the mobile terminal 1 obtained by the measurement in the positioning unit 12 and the position information of the building B1. It is a process which determines. Here, the “relative relationship” is, for example, the distance between the mobile terminal 1 and the building B1. The “determination process” can be said to be a process of determining whether or not the user who owns the mobile terminal 1 is out. The communication unit 14 is configured to transmit the determination result of the determination process to the monitoring system 2.

When the monitoring system 2 receives the determination result that the mobile terminal 1 exists outside the specific area A1 from the communication unit 14 and warning information about the state of the building B1 is generated, the warning information is generated in the mobile terminal 1 Is configured to notify. Here, the “warning information” is information for notifying that the building B1 is in a state to be warned, for example, the window of the building B1 is open.

That is, in the security system 100 of the present embodiment, when the user who owns the mobile terminal 1 is out, the monitoring system 2 notifies the mobile terminal 1 when the building B1 is in a state of caution. For this reason, the user can know that the building B1 is in a state to be warned. In the security system 100 of the present embodiment, the positioning unit 12 used for determining whether or not the user has gone out is not always activated, but is activated according to the detection result of the detection unit 11. . Therefore, in the security system 100 of the present embodiment, it is determined whether or not the user who owns the mobile terminal 1 has gone out while reducing the power consumption of the mobile terminal 1 compared to the case where the positioning unit 12 is always activated. There is an advantage that you can.

(2) Details Hereinafter, the security system 100 of the present embodiment will be described in detail with reference to FIGS. 1 and 2. The security system 100 according to the present embodiment includes a mobile terminal 1, a monitoring system 2 including a parent device 3 and a server 4, and a plurality (here, two) of sensors 5.

The mobile terminal 1 is, for example, a mobile communication terminal such as a smartphone, and includes the detection unit 11, the positioning unit 12, the control unit 13, and the communication unit 14 as described above.

The detection unit 11 is configured to detect the state of the mobile terminal 1. In the present embodiment, the detection unit 11 is configured to measure the number of steps of the user who owns the mobile terminal 1 using an acceleration sensor included in the mobile terminal 1. In other words, the detection unit 11 includes an acceleration sensor that measures the number of steps of the user who owns the mobile terminal 1 as the state of the mobile terminal 1. Note that “acceleration sensor measures the number of steps of the user” here means not only when the acceleration sensor itself has the function of measuring the number of steps of the user, but also indirectly using the acceleration sensor. This also includes the case of measurement. The detection unit 11 compares the measured number of steps of the user with a threshold value stored in advance. And the detection part 11 will start the positioning part 12, if the measured user's step count reaches a threshold value (for example, several hundred steps) within a predetermined period (for example, several minutes). In other words, the positioning unit 12 is configured to be activated when the number of user steps measured by the detection unit 11 reaches a threshold value within a predetermined period.

Here, when the user is in the specific area A1 (that is, at home), it is unlikely that an event that the user keeps walking for a predetermined period of time occurs. Therefore, in the present embodiment, when the detection unit 11 detects an event in which the user continues walking for a predetermined period, the detection unit 11 determines that the user is away from the specific area A1, that is, has a high possibility of going out, The positioning unit 12 is activated. In the present embodiment, the event “the user continues walking” corresponds to the above-described event “the number of steps of the user measured by the detection unit 11 reaches a threshold value within a predetermined period”.

Further, the detection unit 11 is configured to detect a handover for switching the base station BS1 communicating with the mobile terminal 1 as the state of the mobile terminal 1. And the positioning part 12 is comprised so that it may be started if the detection part 11 detects a hand-over. As already described, the mobile terminal 1 is configured to communicate with the base station BS1. And base station BS1 is installed for every hexagonal cell A2 which is the range which the electromagnetic wave which base station BS1 emits reaches, for example. That is, as shown in FIG. 2, a plurality of base stations BS1 and a plurality of cells A2 correspond one-to-one. Hereinafter, among the plurality of cells A2, the cell A2 having the building B1 is also referred to as a first cell A21, and the cells A2 other than the first cell A21 are also referred to as second cells A22.

Here, when the mobile terminal 1 moves from an arbitrary cell A2 to the adjacent cell A2, that is, when the mobile terminal 1 passes through the boundary area A3 of the adjacent cells A2, handover may occur. Therefore, in the present embodiment, when detecting the handover, the detection unit 11 determines that the user is likely moving, and activates the positioning unit 12.

The positioning unit 12 is configured to measure the current position information of the mobile terminal 1 using, for example, the United States GPS (Global Positioning System) as a positioning system. Specifically, the positioning unit 12 calculates the distances between the plurality of positioning satellites S1 and the mobile terminal 1 by receiving data from a plurality of (for example, three or more) positioning satellites S1, respectively. The position information (for example, latitude and longitude) of the mobile terminal 1 is calculated from the distance obtained by the calculation. In FIG. 2, only one positioning satellite S1 is shown.

In the present embodiment, the positioning unit 12 is not always activated, but is configured to be activated according to the detection result of the detection unit 11. That is, the positioning unit 12 is configured to be activated when the state of the mobile terminal 1 is in a specific state, for example, when the detection unit 11 detects a handover. Further, the positioning unit 12 is configured to stop after measuring the position information of the mobile terminal 1. In the present embodiment, the positioning unit 12 is configured to stop when a predetermined time elapses after activation, for example, by measuring with a timer function provided in the mobile terminal 1. This is to prevent the power consumption of the mobile terminal 1 from increasing due to the positioning unit 12 being continuously activated.

The control unit 13 is configured by a computer system having a CPU (Central Processing Unit) and a memory as main components, for example. The computer system functions as the control unit 13 by the CPU executing the program stored in the memory. The program is recorded in advance in the memory of the control unit 13 here, but may be provided by being recorded through a telecommunication line such as the Internet or in a non-temporary recording medium such as a memory card. The control unit 33 of the base unit 3, the processing unit 42 of the server 4, and the monitoring unit 52 of the sensor 5, which will be described later, are also configured by a computer system mainly composed of a CPU and a memory, like the control unit 13.

The registration information of the monitoring system 2 registered in the mobile terminal 1 is stored in the memory of the control unit 13. The registration information is, for example, an identifier of the monitoring system 2 and an encryption key used for communication with the monitoring system 2.

The control unit 13 is configured to execute a determination process. In the present embodiment, the control unit 13 determines the distance between the portable terminal 1 and the building B1 from the position information of the portable terminal 1 obtained by the measurement in the positioning unit 12 and the position information of the building B1 in the determination process. Calculate. In the present embodiment, the position information of the building B1 is stored only in the memory of the control unit 13, that is, only in the mobile terminal 1. And the control part 13 compares the distance between the portable terminal 1 and building B1 with the distance threshold value previously memorize | stored in memory in determination processing. As a result of the comparison, if the distance is equal to or smaller than the distance threshold, the control unit 13 determines that the mobile terminal 1 exists in the specific area A1.

On the other hand, as a result of the comparison, if the distance exceeds the distance threshold, the control unit 13 determines that the mobile terminal 1 exists outside the specific area A1. Then, the control unit 13 transmits the determination result that the mobile terminal 1 exists outside the specific area A1 or the determination result that the mobile terminal 1 exists inside the specific area A1 via the communication unit 14 to the monitoring system 2 (here Then, it transmits to the server 4). In other words, the communication unit 14 is configured to transmit the determination result of the determination process (that is, the determination result of whether or not the user is out) to the monitoring system 2.

When the control unit 13 receives a notification signal (described later) from the server 4 via the communication unit 14, the control unit 13 generates a warning message based on the warning content included in the notification signal, and the generated warning message is displayed on the display. Display or play from the speaker. Alternatively, the control unit 13 displays a warning message included in the notification signal on a display or reproduces it from a speaker. Thereby, the user can know that abnormality (for example, the open state of the window of the building B1, a shutter, a door, etc., or the invasion of the third party into the building B1) generate | occur | produced in the building B1.

The communication unit 14 is configured to communicate with the monitoring system 2 (here, the server 4) via a mobile phone network (carrier network) provided by a communication carrier. Specifically, the communication unit 14 is configured to communicate with the monitoring system 2 via the base station BS1 and the network N1 by communicating with the base station BS1 in the cell A2 in which the mobile terminal 1 exists. Has been. The mobile phone network includes, for example, a 3G (third generation) line, an LTE (Long Termination Evolution) line, and the like.

The base unit 3 is installed, for example, inside the building B1. In the present embodiment, the number of master units 3 used in the security system 100 is one, but when there are a plurality of buildings B1 targeted by the security system 100, a plurality of units may be used according to the number of buildings B1. . In this case, the monitoring system 2 monitors the state of the building B1 for each of the plurality of buildings B1. The base unit 3 includes a first communication unit 31, a second communication unit 32, and a control unit 33.

The first communication unit 31 is a communication interface compliant with, for example, the Ethernet (registered trademark) standard. In the present embodiment, the first communication unit 31 is connected to the network N1 and communicates with the server 4 via the network N1.

The second communication unit 32 is a communication interface for communicating with the sensor 5 installed at the entrance of the building B1. The communication method between the second communication unit 32 and the sensor 5 includes, for example, wired communication, Wi-Fi (registered trademark), Bluetooth (registered trademark), and low power wireless (specific low power) that does not require a license. Wireless). For this type of low-power radio, specifications such as the frequency band to be used and the antenna power are defined in each country depending on the application. In Japan, low-power radio that uses radio waves in the 920 MHz band or 420 MHz band is defined.

In the memory of the control unit 33, registration information of the sensor 5 registered in the parent device 3 is stored. The registration information is, for example, an identifier of the sensor 5 and an encryption key used for communication with the sensor 5. When the control unit 33 receives a monitoring signal (described later) from the sensor 5 via the second communication unit 32, the control unit 33 transmits the received monitoring signal to the server 4 via the first communication unit 31. That is, the base unit 3 functions as a relay that relays communication between the sensor 5 and the server 4.

The server 4 is installed outside the building B1, for example. The server 4 includes a communication unit 41 and a processing unit 42. The communication unit 41 is a communication interface compliant with, for example, the Ethernet (registered trademark) standard, and is configured to communicate with the parent device 3 via the network N1. The communication unit 41 is configured to communicate with the mobile terminal 1 via the network N1 and the base station BS1.

In the memory of the processing unit 42, registration information of the mobile terminal 1 registered in the monitoring system 2 is stored. The registration information is, for example, an identifier of the mobile terminal 1 and an encryption key used for communication with the mobile terminal 1.

The processing unit 42 is configured to manage the outing flag of the user who owns the mobile terminal 1. In this embodiment, when the processing unit 42 receives from the communication unit 41 the determination result that the mobile terminal 1 is outside the specific area A1 (that is, the user is out), the value of the outing flag is set to “true ( True) ”. On the other hand, when the processing unit 42 receives from the communication unit 41 the determination result that the mobile terminal 1 is present in the specific area A1 (that is, the user is at home), the processing unit 42 sets the value of the outing flag to “False”. And

The processing unit 42 is configured to transmit a notification signal to the mobile terminal 1 via the communication unit 41 when warning information regarding the building B1 occurs when the outing flag is “true”. In the present embodiment, the warning information generation condition is to receive a monitoring signal from the sensor 5. The “notification signal” is a signal for notifying the mobile terminal 1 that warning information has occurred, and includes warning contents such as the window of the building B1 being open.

Here, in the present embodiment, as described above, the base unit 3 relays the monitoring signal from the sensor 5 to the server 4. That is, the server 4 can communicate with the sensor 5 via the parent device 3. Further, as will be described later, the monitoring signal from the sensor 5 includes information indicating at least one of the opened state of the entrance / exit of the building B1 and the unlocked state of the entrance / exit. That is, the monitoring system 2 (here, the server 4) receives at least one of the opened state of the entrance / exit of the building B1 and the unlocked state of the entrance / exit from the sensor 5 that can communicate with the monitoring system 2 as warning information. It can be said that it is configured.

Sensor 5 is installed at the entrance of building B1, for example. Here, the “entrance / exit” is a place connecting the space inside the building B1 and the space outside the building B1. That is, the sensor 5 is installed in, for example, a window, a shutter, and a door of the building B1. In this embodiment, the sensor 5 is installed in the door of the entrance of building B1, for example. Moreover, the sensor 5 is installed in the window which is hard to visually recognize from the outside among several windows of the building B1, for example. Of course, the sensor 5 may be installed in all the entrances (windows, shutters, and doors) of the building B1.

The sensor 5 includes a transmission unit 51, a monitoring unit 52, and a power generation unit 53. The transmission unit 51 is a communication interface for communicating with the parent device 3. The communication method between the transmission unit 51 and the parent device 3 is, for example, wired communication, Wi-Fi (registered trademark), Bluetooth (registered trademark), and low power wireless (specific low power wireless) that does not require a license. ) And the like.

The monitoring unit 52 is configured to monitor the state of the entrance / exit of the building B1. For example, when the sensor 5 is installed in the window of the building B1, the monitoring unit 52 monitors whether or not the window is open. Then, when the window is in the open state, the monitoring unit 52 transmits a monitoring signal including information indicating that the window is in the open state to the parent device 3 through the transmission unit 51. For example, when the sensor 5 is installed in the door lock of the building B1, the monitoring unit 52 monitors whether or not the door is unlocked. Then, when the door is in the unlocked state, the monitoring unit 52 transmits a monitoring signal including information indicating that the door is in the unlocked state to the parent device 3 via the transmission unit 51. That is, the monitoring unit 52 is configured to monitor the entrance / exit of the building B1 and transmit the monitoring result (monitoring signal) to the monitoring system 2 (here, the parent device 3).

In the memory of the monitoring unit 52, registration information of the parent device 3 registered in the sensor 5 is stored. The registration information is, for example, an identifier of the parent device 3 and an encryption key used for communication with the parent device 3.

The power generation unit 53 is a vibration type power generation device that generates power by converting vibration energy into electrical energy using a piezoelectric element, or an electromagnetic induction type power generation device that generates an induced voltage in the coil by relative movement between the coil and the permanent magnet. And so-called energy harvester. For example, when the sensor 5 is installed in the crescent lock of the window of the building B1, the power generation unit 53 generates power by an operation of locking or unlocking the crescent lock. That is, the power generation unit 53 is configured to generate electric power by movement (for example, locking / unlocking of windows, etc.) of a part constituting a part of the entrance / exit of the building B1.

And in this embodiment, the monitoring part 52 is comprised so that the electric power supply from the electric power generation part 53 may be received and driven. That is, the monitoring unit 52 is not driven unless the power generation unit 53 generates power by, for example, opening and closing the window. In other words, the monitoring unit 52 is driven only when an operation such as opening / closing of a window occurs.

(3) Operation Hereinafter, the operation of the security system 100 of the present embodiment will be described. First, the operation of the security system 100 when the mobile terminal 1 is present in the specific area A1, that is, when the user is at home will be described with reference to FIG. The detection unit 11 of the mobile terminal 1 measures the number of steps of the user for a predetermined period using the acceleration sensor (step S100). Then, the detection unit 11 compares the measured number of steps of the user with a threshold (step S101). If the measured number of steps of the user does not exceed the threshold within the predetermined period (step S101: No), the detection unit 11 resets the measurement value and measures the number of steps of the user again (step S100). On the other hand, if the measured number of steps of the user is greater than or equal to the threshold within a predetermined period (step S101: Yes), the detection unit 11 determines that the user is likely to exist outside the specific area A1, and determines the positioning unit. 12 is activated (step S102).

The positioning unit 12 measures the position information of the mobile terminal 1 by communicating with a plurality of positioning satellites S1 (step S103). And the control part 13 performs a determination process using the positional information on the portable terminal 1 measured by the positioning part 12 (step S104). In the determination process, when it is determined that the mobile terminal 1 is in the specific area A1 (step S104: No), the control unit 13 determines that the user is at home (step S105). After that, the positioning unit 12 stops when a predetermined time has elapsed since activation (step S106). And the detection part 11 resets a measured value, and measures a user's step count again (step S100).

On the other hand, when it is determined that the mobile terminal 1 is outside the specific area A1 (step S104: Yes), the control unit 13 determines that the user is out (step S107). And the control part 13 transmits a determination result to the monitoring system 2 (here server 4) via the communication part 14 (step S108). Thereby, in the monitoring system 2, the outing flag is changed from “false” to “true”. Therefore, the monitoring system 2 transmits a notification signal to the portable terminal 1 when the warning information such as the window of the building B1 being open is generated while the outing flag is “true”, so that the building B1 Inform users that they are in a state of caution.

After that, the positioning unit 12 stops when a predetermined time elapses after starting (step S109). Thereafter, the detection unit 11 determines that the mobile terminal 1 is present in the first cell A21 by the determination process of the control unit 13, that is, the user is in the second cell A22 different from the first cell A21 including the specific area A1. Until the return to the first cell A21, the measurement using the acceleration sensor is not performed, and only the handover detection described below is performed.

Next, the operation of the security system 100 when the mobile terminal 1 is outside the specific area A1, that is, when the user is out is described with reference to FIG. In a state where the user is determined to be out, when the number of steps of the user is measured, the positioning unit 12 is activated using this as a trigger, thereby increasing the power consumption of the mobile terminal 1. Therefore, in a state in which it is determined that the user is out, the detection unit 11 does not perform measurement using the acceleration sensor, and detects only a handover (step S110).

When the detection unit 11 detects a handover (step S110: Yes), the detection unit 11 activates the positioning unit 12 (step S111). The positioning unit 12 measures the position information of the mobile terminal 1 by communicating with a plurality of positioning satellites S1 (step S112). And the control part 13 performs a determination process using the positional information on the portable terminal 1 measured by the positioning part 12 (step S113). In this determination process, it is determined whether or not the mobile terminal 1 exists in the specific area A1, and whether or not the mobile terminal 1 exists in the first cell A21 (that is, the cell A2 in which the building B1 is located). Determine whether or not.

In the determination process, when it is determined that the mobile terminal 1 does not exist in the first cell A21 (step S113: No), the control unit 13 determines that the user is still out (step S114). After that, the positioning unit 12 stops when a predetermined time has elapsed since activation (step S115). And the detection part 11 starts the detection of a handover again (step S110).

On the other hand, when it is determined that the mobile terminal 1 is present in the first cell A21 (step S113: Yes), the control unit 13 determines that the user is returning home (step S116). After that, the positioning unit 12 stops when a predetermined time has elapsed since activation (step S117). Thereafter, the detection unit 11 stops detecting the handover and starts measurement using the acceleration sensor again (step S100 in FIG. 3). That is, when the control unit 13 determines that the mobile terminal 1 is present in the cell A2 of the cell A2 in which the building B1 is located, the detection unit 11 detects other than the presence or absence of handover as the state of the mobile terminal 1. It is configured.

After that, when the user returns to the specific area A1, the control unit 13 determines that the mobile terminal 1 exists in the specific area A1 (step S105 in FIG. 3). Then, the control unit 13 transmits the determination result to the monitoring system 2 via the communication unit 14. Thereby, in the monitoring system 2, the outing flag is changed from “true” to “false”. Therefore, since the user is at home thereafter, the monitoring system 2 transmits a notification signal to the portable terminal 1 even if warning information about the building B1 occurs until the next outing flag becomes “true”. Never do.

On the other hand, if the user does not return to the specific area A1, the control unit 13 determines that the mobile terminal 1 exists outside the specific area A1 (step S107 in FIG. 3). In this case, the control unit 13 does not transmit the determination result to the monitoring system 2. That is, in this case, the outing flag remains “true”.

By the way, when the user is at home and, for example, the user goes out in a car in the immediate vicinity of the building B1, the user's step count cannot be measured, and the positioning unit is triggered by the measurement by the acceleration sensor in the detection unit 11. 12 may not be activated. In this case, the detection unit 11 can activate the positioning unit 12 by detecting a handover that occurs when the vehicle passes through the boundary region A3. That is, in a state where it is determined that the user is at home, the detection unit 11 preferably performs both measurement by the acceleration sensor and detection of the handover.

(4) Modified Example In the present embodiment, the detection unit 11 measures the number of steps of the user who owns the mobile terminal 1 as the state of the mobile terminal 1, but may have other configurations. For example, the detection unit 11 may be configured to measure the number of steps of the user using a pedometer included in the mobile terminal 1. As the pedometer, for example, a piezoelectric sensor type using a mechanism in which a voltage is generated in accordance with vertical acceleration caused by movement can be used.

Also, the detection unit 11 may be configured to activate the positioning unit 12 based on, for example, an acceleration detection result by an acceleration sensor. That is, the detection unit 11 may be configured to detect the moving speed of the mobile terminal 1 as the state of the mobile terminal 1. Moreover, the detection part 11 may be the structure which starts the positioning part 12 based on the detection result of the angular velocity in a gyro sensor, for example, when the portable terminal 1 is provided with a gyro sensor. That is, the detection unit 11 may be configured to detect the inclination of the mobile terminal 1 as the state of the mobile terminal 1. In addition, the detection unit 11 may be configured to activate the positioning unit 12 when detecting connection by Bluetooth (registered trademark) between the mobile terminal 1 and a device outside the home (for example, in-vehicle device). That is, the detection unit 11 may be configured to detect the communication state of the mobile terminal 1 as the state of the mobile terminal 1.

In the present embodiment, the threshold used when the detection unit 11 compares the number of steps with the user may be changeable by a user operation, for example. Moreover, the distance threshold value which prescribes | regulates the range of specific area A1 which the control part 13 uses in a determination process may be changeable by a user's operation, for example. That is, at least one of the reference (here, the threshold value) at which the positioning unit 12 is activated and the range (here, the distance threshold value) of the specific area A1 may be changeable.

By the way, in principle, the mobile terminal 1 cannot know in which cell A2 the current position is (for example, whether the current position is in the first cell A21). If the mobile terminal 1 has a function of acquiring information on whether or not the current position of the mobile terminal 1 is in which cell A2 from the telecommunications carrier, the detection unit 11 indicates that the mobile terminal 1 is in the second cell. When it is located at A22, it is preferable not to perform measurement by the acceleration sensor. That is, in this case, it is preferable not to activate the positioning unit 12.

In the present embodiment, the positioning system used by the positioning unit 12 is the US GPS, but the positioning unit 12 may use a positioning system other than the GPS. Examples of the positioning system include Japanese QZSS (Quasi-Zenith Satellite System), Russian GLONASS (Global Navigation Satellite System), and China's Compass. Other positioning systems include Galileo in Europe and IRNSS (Indian Regional Navigation Satellite System) in India. In addition, the positioning unit 12 not only uses a single positioning system, but also uses a positioning system that combines other positioning technologies so as to complement the positioning by the positioning system, such as DGPS (Differential GPS). Also good.

In the present embodiment, the control unit 13 calculates the distance between the mobile terminal 1 and the building B1 as a relative relationship between the position information of the mobile terminal 1 and the position information of the building B1 in the determination process. However, other configurations may be used. For example, the control unit 13 determines whether or not the position information of the mobile terminal 1 is included in the specific area A1 recorded in the map data stored in the memory in advance in the determination process. You may determine whether the terminal 1 exists in specific area A1.

In the present embodiment, there is one mobile terminal 1 used in the security system 100. However, when there are a plurality of users using the security system 100 such as a family, there are a plurality of terminals according to the number of users. Also good. When there are a plurality of mobile terminals 1, the monitoring system 2 (here, the server 4) sets the outing flag to “true” when receiving a determination result that the user has gone out from all the mobile terminals 1. It is preferable to be configured to do so. This is because it is not necessary for the monitoring system 2 to transmit a notification signal to the mobile terminal 1 if at least one user is at home.

In the present embodiment, the mobile terminal 1 is configured by one mobile communication terminal such as a smartphone, but may have other configurations. For example, the mobile terminal 1 may be separated into a main terminal and a sub terminal. As an example, the mobile terminal 1 may be separated into a smartphone that is a main terminal and a wearable device that is a sub-terminal. In this case, the smartphone and the wearable device can perform two-way communication by wireless communication using, for example, Bluetooth (registered trademark).

In addition, for example, the mobile terminal 1 may be separated into a smartphone as a main terminal and a temperature sensor as a sub terminal. In this case, the detection unit 11 may be configured to activate the positioning unit 12 based on a change in temperature detected by the temperature sensor (for example, a temperature change accompanying movement from the room to the room). That is, the detection unit 11 may be configured to detect a part of the temperature of the mobile terminal 1 as the state of the mobile terminal 1.

In the present embodiment, the sensor 5 is configured to monitor the entrance / exit of the building B1 by being installed at the entrance / exit of the building B1, but may have other configurations. For example, the sensor 5 may be installed in a switch such as a lighting of the building B1, air conditioning equipment, and electrical appliances. In this case, the power generation unit 53 of the sensor 5 can generate power by an on / off switching operation of the switch. In this case, if it is assumed that a third party who has entered the building B1 operates the switch, the monitoring unit 52 of the sensor 5 monitors the on / off state of the switch so that the third party enters the building B1. Can be monitored. That is, in this case, it can be said that the monitoring unit 52 of the sensor 5 indirectly monitors the entrance / exit of the building B1.

In the present embodiment, the building B1 is a detached house, but the present invention is not limited to this. For example, the building B1 may be a dwelling unit of an apartment house or a building office. That is, building B1 should just be the whole or a part of building which a user goes in and out. And a user should just be a user of building B1, and does not need to live in building B1.

In the present embodiment, the specific area A1 is the site of the building B1 including the building B1, but the purpose is not limited to this. For example, the specific area A1 may be only the building B1, or may be an area (including a site) with a radius of several meters to several kilometers around the building B1. Further, the shape of the specific area A1 is not limited to a circular shape, but may be other shapes such as a polygonal shape.

In the present embodiment, the monitoring system 2 includes the parent device 3 and the server 4, but the present invention is not limited to this. For example, the monitoring system 2 may be configured only by the parent device 3 or may be configured only by the server 4. In the monitoring system 2, cloud computing may be used instead of the server 4. That is, in the monitoring system 2, a plurality of functions may be combined into one device, or may be distributed among a plurality of devices.

Further, functions similar to those of the security system 100 may be embodied by a program, a non-transitory recording medium storing the program, a determination method, or the like. A program according to an aspect causes a computer system to execute a detection process, a positioning process, a determination process, and a transmission process. The detection process is a process for detecting the state of the mobile terminal 1. The positioning process is a process that is executed according to the detection result in the detection process, measures the position information of the portable terminal 1 using a positioning system including the positioning satellite S1, and ends after the measurement. In the determination process, the mobile terminal 1 exists in the specific area A1 based on the relative relationship between the position information of the mobile terminal 1 obtained by the measurement in the positioning process and the position information of the building B1 in the specific area A1. This is a process for determining whether or not to do so. The transmission process is a process of transmitting the determination result in the determination process to the monitoring system 2 that is at least partially installed in the building B1 and monitors the state of the building B1.
