Embodiments for Carrying Out the Invention

[0013] Embodiments of the present disclosure will be described with reference to the drawings. The same or corresponding components may be denoted by the same reference numerals, and repeated descriptions may be omitted.

[0014] Embodiment 1 FIG. 1 is a configuration example of a monitoring system 100 according to Embodiment 1 of the present disclosure. The monitoring system 100 includes a human detection device 2 installed in each house. Here, a wireless terminal 1, an alarm device 4, and a lighting fixture 5 are further installed.

[0015] Hereinafter, the alarm device 4 and the lighting fixture 5 are collectively referred to as a controlled device 10.

[0016] The human detection device 2 is installed so that the detection area is a place where danger is assumed for the person to be monitored 50. The human detection device 2 is installed, for example, near a window. This is assuming the possibility that a child or the like may fall from the window. Also, the human detection device 2 may be installed near a door. This is assuming the possibility that an elderly person suffering from dementia or the like may escape from indoors and wander.

[0017] When it is recognized that a person is detected in the human detection device 2, the determination circuit 21 included in the human detection device 2 transmits an alarm command signal for instructing an alarm notification to the wireless terminal 1 and the controlled device 10.

[0018] Note that the determination circuit 21 does not necessarily have to be built in the human detection device 2 and may be external.

[0019] The wireless terminal 1 is a mobile terminal such as a smartphone owned by the caregiver 30. The wireless terminal 1 that has received an alarm command signal from the determination circuit 21 notifies the caregiver 30 of the alarm in a set manner.

[0020] In addition, the lighting fixture 5 that has received an alarm command signal from the determination circuit 21 notifies the caregiver 30 of the alarm in a set manner. The notification method by the lighting fixture 5 is a change in the lighting state such as the blinking of the light source or the change in the color temperature.

[0021] In addition, the notification device 4 that has received an alarm command signal from the determination circuit 21 notifies the caregiver 30 of the alarm based on a predetermined method. The predetermined method is light emission, vibration, the sounding of a buzzer, etc.

[0022] By installing the notification device 4 in a place where the notification of the alarm by the lighting fixture 5 does not reach, it becomes possible to notify the caregiver 30 thoroughly.

[0023] FIG. 2 is a detailed configuration example of the monitoring system 100 according to Embodiment 1 of the present disclosure. The wireless terminal 1 includes a control circuit 11, an input device 12, a communication device 13, and a display 14.

[0024] The input device 12 is a user interface that receives inputs from users such as caregivers. Through the input device 12, the user can input settings desired by himself / herself. For example, for the lighting fixture 5, the lighting state when notifying an alarm can be set. Also, for the notification device 4, the sounding time, sounding interval, etc. of the buzzer when notifying an alarm can be set. Also, for the wireless terminal 1, the notification means when notifying an alarm can be set from, for example, display by the display 14, vibration of the vibrator, voice, push notification, alarm, etc.

[0025] The control circuit 11 generates a command signal for realizing the settings input by the user and transmits it to the target person detection device 2 or the controlled device 10 via the communication device 13.

[0026] The display 14 displays the settings input by the user, the content of the alarm regarding the person under surveillance, etc. Note that the input device 12 and the display 14 may be integrated using a touch panel or the like.

[0027] The communication device 13 performs short-range wireless communication with the person detection device 2 and the controlled device 10. Examples of the communication means include Bluetooth (registered trademark) Classic compliant with the IEEE802.15.1 standard, or Bluetooth (registered trademark) Low Energy (BLE).

[0028] Figure 3 is a flowchart of the processing executed by the wireless terminal 1 at the start of use of the surveillance system 100 according to Embodiment 1 of the present disclosure.

[0029] First, the process starts. Next, a wireless connection is made to the person detection device 2 and the controlled device 10. Note that the wireless communication method here is not limited to short-range wireless communication, and for example, Wi-Fi (registered trademark) compliant with the wireless standard IEEE802.11 may also be used.

[0030] Furthermore, a command signal for realizing the settings desired by the user is generated for the person detection device 2 and the controlled device 10, and transmitted to the target device (step S02).

[0031] Next, mutual authentication in short-range wireless communication is performed between the person detection device 2 and the controlled device 10, and they are paired and connected (step S03). Finally, the process ends.

[0032] By mutually authenticating the wireless terminal 1 and other devices prior to the start of use in this way, the connection is automatically completed and short-range wireless communication becomes possible after the start of use. Note that if the determination circuit 21 is not built into the person detection device 2, it should be noted that the wireless terminal 1 also makes a pairing connection with the determination circuit 21 in step S03.

[0033] FIG. 4 is a flowchart of the process executed by the determination circuit 21 according to Embodiment 1 of the present disclosure. First, the process starts. Next, it is determined whether a person has been detected by the person detection device 2 (step S11). If detection is confirmed, it is determined whether the state in which the person has been detected has continued for a first period (step S12). If continuation is confirmed, it means that a person has stayed in a place where danger is assumed for a long time. Therefore, the determination circuit 21 transmits an alarm command signal to the wireless terminal 1 and other controlled devices 10 by short-range wireless communication (step S13). Finally, the process ends.

[0034] On the other hand, if the continuation of the first period is not confirmed in step S12, it can be said that the person has left the area where danger is assumed and the dangerous state has been avoided. In this case, the process returns to step S11.

[0035] On the other hand, if no person is detected in step S11, it is further determined whether the state of not detecting a person has continued for a second period (step S14). If continuation is confirmed, it can be said that no one is staying in the place where danger is assumed and the state is not dangerous. In this case, the determination circuit 21 transmits a signal indicating that there is no need to notify an alarm to the wireless terminal 1 and other controlled devices 10 (step S15), and the process ends. On the other hand, if continuation is not confirmed, the process returns to step S11.

[0036] Note that the first period and the second period may be set by the user using the wireless terminal 1.

[0037] As described above, in the present disclosure, an alarm command signal from the person detection device 2 is transmitted to the wireless terminal 1 via short-range wireless communication. Thereby, it is possible to provide a monitoring system and a monitoring method capable of directly transmitting an alarm command from the person detection device to the wireless terminal owned by the caregiver.

[0038] <Modification Example of Embodiment 1> FIG. 5 is a modification of FIG. 4. First, the process starts. Next, it is determined whether a person has been detected by the person detection device 2 (step S21). If detection is confirmed, it is determined whether short-range wireless communication by pairing connection is possible with the wireless terminal 1 (step S22). If short-range wireless communication is possible, it can be said that the person detected by the person detection device 2 is the guardian 30 who owns the wireless terminal 1. Even if it is a place where danger is assumed for the person under guardianship 50, if the guardian 30 is staying there, there is no danger, so in this case, the process returns to step S21.

[0039] On the other hand, if short-range wireless communication is not possible in step S22, it can be said that the person detected by the person detection device 2 is not the guardian 30. In this case, as in FIG. 4, it is determined whether the state of detecting the person has continued for the first period (step S23). If continuation is confirmed, an alarm command signal is transmitted to the wireless terminal 1 and other controlled devices 10 by short-range wireless communication as in FIG. 4 (step S24). Finally, the process ends.

[0040] On the other hand, if continuation of the first period is not confirmed in step S23, the process returns to step S21 as in FIG. 4.

[0041] On the other hand, if no person is detected in step S21, it is further determined whether the state of not detecting a person has continued for the second period (step S25). If continuation is confirmed, a signal indicating that there is no need to notify an alarm to the wireless terminal 1 and other controlled devices 10 is transmitted as in FIG. 4 (step S26), and the process ends. On the other hand, if continuation is not confirmed, the process returns to step S21.

[0042] In this way, by determining whether short-range wireless communication by pairing connection is possible with the wireless terminal 1, it becomes possible to determine whether the person detected by the person detection device 2 is the guardian 30. Thereby, it can be used as a material for determining the danger in the detection area, and the accuracy of the alarm can be improved.

[0043] Embodiment 2 In this embodiment, based on the beacon signal from the transmitter 3 carried by the person under care 50, the human detection device 2 determines whether the detected person is the person under care 50. Hereinafter, the points of change from Embodiment 1 will be described.

[0044] FIG. 6 is a configuration example of the monitoring system 100 according to Embodiment 2 of the present disclosure. Here, the person under care 50 carries the transmitter 3. Also, here, the wireless terminal 1, the notification device 4, and the lighting fixture 5 are not shown.

[0045] FIG. 7 is a flowchart of the process executed by the determination circuit 21 according to Embodiment 2 of the present disclosure.

[0046] First, the process starts. Next, it is determined whether a person has been detected by the human detection device 2 (step S31). If detection is confirmed, it is determined whether a beacon signal has been received from the transmitter 3 (step S32). If reception of the beacon signal is confirmed, it can be said that the detected person is the person under care 50. In this case, it is determined whether the state of detecting the person under care has continued for the first period (step S33). If it is determined that it has continued, an alarm command signal is transmitted to the wireless terminal 1 and other controlled devices 10 by short-range wireless communication as in Embodiment 1 (step S34). Finally, the process ends.

[0047] On the other hand, if reception of the beacon signal is not confirmed in step S32, it can be said that the person detected by the human detection device 2 is not the person under care 50. In this case, the process returns to step S31.

[0048] On the other hand, if it is not determined that the first period has continued in step S33, the process returns to step S31 as in Embodiment 1.

[0049] On the other hand, if no person is detected in step S31, it is further determined whether the state of not detecting a person continues for a second period (step S35). If the continuation is confirmed, a signal indicating that there is no need to notify an alarm to the wireless terminal 1 and other controlled devices 10 is transmitted in the same manner as in the first embodiment (step S36), and the process ends. On the other hand, if the continuation is not confirmed, the process returns to step S31.

[0050] By thus determining whether or not the beacon signal from the transmitter 3 carried by the person 50 to be watched is received, it becomes possible to determine whether the person detected by the person detection device 2 is the person 50 to be watched. Thereby, it becomes possible to improve the accuracy of the alarm as compared with the first embodiment.

[0051] <Modification Example of Embodiment 2> Note that the caregiver 30 may also carry a transmitter, and when a person is detected by the person detection device 2, a process of determining whether or not a beacon signal from the transmitter owned by the caregiver 30 is received may be further executed. In this case, it is assumed that the alarm command signal is not executed when the beacon signal from the transmitter owned by the caregiver 30 is received. Thereby, it becomes possible to further improve the accuracy of the alarm.

[0052] Note that the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof at the implementation stage. Also, the respective embodiments may be combined and implemented as appropriate, and in that case, the combined effects can be obtained.
