Mode for Carrying Out the Invention

[0006] [Configuration of Monitoring System] FIG. 1 is a diagram showing an example of the device configuration of the monitoring system 1 of the present embodiment. The monitoring system 1 includes a terminal device 10, a server device 20, a communication device 30, and a remote control device 40. The monitoring system 1 provides a monitoring service for a monitor to monitor the situation of a person to be monitored.

[0007] In the following description, the person to be monitored is also referred to as the person under guardianship or the object of guardianship. The monitoring service provided by the monitoring system 1 is also referred to as a guardianship service. Further, the monitor is also referred to as a guardian, a user of the guardianship service, or a user. That is, the monitoring system 1 provides a guardianship service for a guardian to monitor the state and actions of the person under guardianship. As an example, the person under guardianship is a non-cohabiting family member of the guardian. The monitoring system 1 provides a function that enables the guardian to remotely monitor the situation of the person under guardianship.

[0008] The terminal device 10 is a device used by a guardian, that is, a user. The terminal device 10 is, for example, a device such as a smartphone, a tablet, or a personal computer, and performs information communication with the server device 20 via the network N1. The server device 20 is a computer device operated by a provider of the guardianship service. The server device 20 performs various settings in the monitoring system 1 and holds and provides information acquired by the monitoring system 1. The communication device 30 includes, for example, an imaging unit 350 (imaging device) such as a camera, and images the monitoring target area A. The communication device 30 performs information communication with the server device 20 via the network N2. The remote control device 40 is a device used by the person under guardianship. The remote control device 40 performs information communication with the communication device 30 by short-range wireless communication, infrared communication, or the like.

[0009] Note that the monitoring system 1 may include a plurality of terminal devices 10, communication devices 30, and remote control devices 40, respectively. As an example, the monitoring system 1 can be configured to set a plurality of caregivers, and each caregiver uses one terminal device 10. For example, if there are siblings among the caregivers, the parent who is the person to be monitored can be configured to be monitored by a plurality of caregivers (siblings) respectively. In addition, the monitoring system 1 can be configured to install communication devices 30 in each room of a building to monitor the status and actions of the persons to be monitored in each room. For example, when there are a plurality of rooms in a building, the monitoring system 1 can set the first room (for example, a living room) as a monitoring target area A1 and the second room (for example, a bedroom) as a monitoring target area A2, and be configured to monitor the status and actions of the persons to be monitored in each room. In addition, the monitoring system 1 can be configured to allow a plurality of persons to be monitored living in a building to use the remote control device 40 respectively. For example, when the persons to be monitored are the parents of the caregiver, the father and the mother can be configured to use the remote control device 40 respectively. In addition, the monitoring system 1 can monitor not only one building but also a plurality of buildings. For example, when the caregiver has a spouse, the monitoring system 1 can set the first building where the caregiver's own parent lives as a monitoring target area A1 and the second building where the caregiver's spouse's parent lives as a monitoring target area A2, and be configured to monitor the status and actions of the persons to be monitored in each building.

[0010] In the following description, when distinguishing a plurality of terminal devices 10 respectively, the first terminal device 10 is described as the terminal device 10-1, the second terminal device 10 is described as the terminal device 10-2, and so on. In addition, when distinguishing a plurality of communication devices 30 respectively, the first communication device 30 is described as the communication device 30-1, the second communication device 30 is described as the communication device 30-2, and so on. Next, with reference to FIG. 2, the functional configurations of the devices of the monitoring system 1 will be described.

[0011] [Functional Configuration of Monitoring System] FIG. 2 is a diagram showing an example of the functional configuration of the monitoring system 1 of the present embodiment.

[0012] [Functional Configuration of Terminal Device] The terminal device 10 includes a terminal operation detection unit 110, a presentation unit 120, a terminal control unit 130, a terminal communication unit 140 (reception unit), a terminal sound collection unit 150, and a terminal sound output unit 160. The terminal operation detection unit 110 includes, for example, an operation device such as a touch panel or an operation switch, and detects an operation on the operation device by a user of the terminal device 10. When the terminal operation detection unit 110 detects an operation, it generates operation information indicating the detected operation and outputs it to the terminal control unit 130. The presentation unit 120 includes, for example, a liquid crystal display, and presents an image based on the control of the terminal control unit 130. The terminal control unit 130 includes, for example, a microcomputer, and controls each part of the terminal device 10. The terminal communication unit 140 performs information communication with the server device 20 based on the control of the terminal control unit 130.

[0013] The terminal sound collection unit 150 includes, for example, a microphone, and collects the sound around the terminal device 10. The terminal sound collection unit 150 outputs the information of the collected sound to the terminal control unit 130. Note that the terminal device 10 may operate each function of the terminal control unit 130 (for example, perform voice recognition) based on the collected sound. In this case, the terminal sound collection unit 150 can also be said to be an example of the terminal operation detection unit 110 that operates the terminal device 10 by sound. The terminal sound output unit 160 includes, for example, a speaker, and outputs sound based on the control of the terminal control unit 130. Note that the terminal device 10 may alert the user by the emitted sound (for example, emit an alarm sound). In this case, the terminal sound output unit 160 can also be said to be an example of the presentation unit 120 that presents information by sound.

[0014] [Functional Configuration of Server Device] The server device 20 includes a server communication unit 210 and a server storage unit 220. The server communication unit 210 performs information communication with the terminal device 10 and the communication device 30. The server storage unit 220 includes a storage device such as a semiconductor memory and stores various types of information. An example of the information stored in the server storage unit 220 will be described with reference to FIG. 3.

[0015] FIG. 3 is a diagram showing an example of the setting information of the monitoring system 1 of the present embodiment. As described above, in the monitoring system 1, the terminal device 10 can monitor a plurality of monitored targets. In this example, among the plurality of monitored targets a to c, the terminal devices 10-1 and 10-2 have the monitored targets a to c set as the monitoring targets. In addition, for the terminal device 10-3, the monitored targets a to b are set as the monitoring targets, but the monitored target c is not set as the monitoring target. Also, when a plurality of terminal devices 10 monitor one monitored target, among these plurality of terminal devices 10, it is possible to set the terminal device 10 that functions as the main monitoring device and the terminal device 10 that functions as the sub-monitoring device. For example, for the monitored target a, the terminal device 10-1 functions as the main monitoring device, and the terminal devices 10-2 and 10-3 function as sub-monitoring devices. In the monitoring system 1, different functions can be provided between the main monitoring device and the sub-monitoring device. The setting information as shown in FIG. 3 is stored in the server storage unit 220. This setting information is referred to as necessary from the terminal device 10 or the communication device 30.

[0016] Here, different operation authorities may be given to the user of the main monitoring device and the user of the sub-monitoring device. For example, the user of the main monitoring device may be given the right to view real-time videos regardless of whether the person being monitored gives permission, and the user of the sub-monitoring device may be prohibited from viewing real-time videos without the permission of the person being monitored. Also, although the operation authority has been described here in two levels of main and sub, it is not limited to this, and the operation authority may be set by being divided into three or more levels. That is, each of the plurality of users is given the operation authority at any one of at least two levels of operation authority, and the presentation unit 120 presents the content based on the operation authority given to the user.

[0017] This operation authority may be given for each monitored area A (that is, the location to be monitored). That is, there are a plurality of locations to be monitored, the operation authority of the user is given for each location to be monitored, and the presentation unit 120 of the terminal device 10 presents the content based on the operation authority given to the user for each location to be monitored.

[0018] [Functional Configuration of Communication Device] Returning to FIG. 2, the communication device 30 includes functions of a first communication unit 310, a second communication unit 320, a communication device control unit 330, a measurement unit 340, an imaging unit 350, a communication device sound collection unit 360, a communication device sound generation unit 370, an operation detection unit 380, and a communication device storage unit 390.

[0019] The first communication unit 310 performs information communication with the remote control device 40 based on the control of the communication device control unit 330. The second communication unit 320 performs information communication with the server device 20 based on the control of the communication device control unit 330.

[0020] Incidentally, as described above, the second communication unit 320 communicates with the terminal device 10 via the server communication unit 210 of the server device 20. However, in the following description, the explanation that the server device 20 mediates the communication between the terminal device 10 and the communication device 30 will be omitted, and for example, it may be described that the second communication unit 320 transmits the first operation information to the terminal device 10.

[0021] The measurement unit 340 measures various situations in the monitoring target area A. For example, the measurement unit 340 may include a temperature sensor and a humidity sensor, and measure the temperature and humidity of the monitoring target area A. Further, the measurement unit 340 may include an infrared sensor and measure the movement of people in the monitoring target area A. The imaging unit 350 includes, for example, a camera, and images the monitoring target area A based on the control of the communication device control unit 330.

[0022] Note that the measurement unit 340 and the imaging unit 350 are collectively referred to as a detection unit. That is, the communication device 30 detects various situations in the monitoring target area A by the detection unit. In addition to the imaging unit 350, the detection unit may have a determination unit (not shown) that determines the state of the monitoring target based on the video imaged by the imaging unit 350. The determination unit performs, for example, posture analysis of the person to be monitored based on the result of machine learning, and determines whether an abnormality has occurred in the person to be monitored, such as the person to be monitored falling. The determination unit outputs the determination result to the communication device control unit 330.

[0023] The communication device control unit 330 includes, for example, a microcomputer, and controls each unit of the communication device 30 including the first communication unit 310, the second communication unit 320, and the imaging unit 350.

[0024] The communication device sound collection unit 360 includes, for example, a microphone, and collects the sound around the communication device 30. The communication device sound collection unit 360 outputs the information of the collected sound to the communication device control unit 330. The communication device sound generation unit 370 includes, for example, a speaker, and generates sound based on the control of the communication device control unit 330. The operation detection unit 380 detects operations on an operation unit (not shown) such as a switch provided in the communication device 30. As an example, the communication device 30 includes an operation mode switching switch (not shown). The operation detection unit 380 detects the setting state of the operation mode switching switch and outputs it to the communication device control unit 330.

[0025] The communication device storage unit 390 includes a storage device such as a semiconductor memory and stores various types of information. As an example, the communication device storage unit 390 stores information on an image (e.g., a moving image) captured by the imaging unit 350 and information on sound collected by the communication device sound collection unit 360.

[0026] [Functional Configuration of Remote Control Device] The remote control device 40 includes an emergency button 410, an OK button 420, an NG button 480, a remote control communication unit 430, a remote control control unit 440, a remote control sound collection unit 450, a remote control sound generation unit 460, and a voltage detection unit 470. Note that the OK button 420 is an operation button indicating consent, approval, or an affirmative answer and is also referred to as a "yes button". The NG button 480 is an operation button indicating disagreement, rejection, or a negative answer and is also referred to as a "no button".

[0027] The emergency button 410 is a button operated by the person under surveillance when some abnormality occurs to the person under surveillance. The OK button 420 is a button operated by the person under surveillance when a permission request is made to the person under surveillance from the monitoring system 1 and the person under surveillance permits the request.

[0028] The remote control communication unit 430 performs information communication with the communication device 30 based on the control of the remote control control unit 440.

[0029] The remote control control unit 440 includes, for example, a microcomputer and controls each part of the remote control device 40. For example, when the remote control control unit 440 detects an operation on the emergency button 410, it generates first operation information, which is information indicating that the emergency button 410 has been operated. The remote control control unit 440 transmits the generated first operation information to the communication device 30 via the remote control communication unit 430. Similarly, when the remote control control unit 440 detects an operation on the OK button 420, it generates second operation information, which is information indicating that the OK button 420 has been operated. The remote control control unit 440 transmits the generated second operation information to the communication device 30 via the remote control communication unit 430.

[0030] The remote control sound collection unit 450 includes, for example, a microphone and collects sounds around the remote control device 40. The remote control sound collection unit 450 outputs the information of the collected sound to the remote control control unit 440. The remote control sound emission unit 460 includes, for example, a speaker and emits sound based on the control of the remote control control unit 440. The voltage detection unit 470 detects the voltage value of the operating power supply of the remote control device 40. The voltage detection unit 470 outputs the detected voltage value of the operating power supply to the remote control control unit 440. When the voltage value detected by the voltage detection unit 470 is equal to or less than a predetermined value, the remote control control unit 440 transmits voltage drop information to the communication device 30 via the remote control communication unit 430.

[0031] [Description of Each Function] Next, each function provided by the monitoring system 1 and its operation will be described with reference to the drawings. In the following description, application software (hereinafter also simply referred to as an app) provided by the monitoring system 1 is installed in the terminal device 10. The terminal control unit 130 controls each part of the terminal device 10 based on the installed app. On the presentation unit 120 of the terminal device 10, a screen defined by the app is displayed. On the presentation unit 120, an initial setting screen is displayed at the first app startup after the app is installed in the terminal device 10.

[0032] [Initial Settings] Figures 4A to 4B are diagrams showing an example of the initial setting screen of the present embodiment. Figure 4A shows an example of the notification setting screen. The monitoring system 1 provides a function for initially setting the situations to be notified to the terminal device 10 among the situations regarding the person under care. An example of the situations to be notified is shown below.

[0033] · Emergency notification: When the emergency button 410 is operated. · Fall: When the person under care falls within the monitored area A. · Temperature and humidity abnormality: When the temperature or humidity in the monitored area A is outside the predetermined range. · Safety confirmation abnormality: When there is no response to the call to the person under care. · Camera abnormality: When an abnormality such as a failure occurs in the imaging unit 350. · Routine deviation: When the behavior of the person under care is different from normal.

[0034] The user operates the notification setting screen displayed on the presentation unit 120 of the terminal device 10 and selects the situations to be notified from among a plurality of types of situations. The terminal device 10 transmits the selected notification settings to the server device 20. The server device 20 stores the received notification settings in the server storage unit 220. The monitoring system 1 notifies the terminal device 10 when the set situation occurs. In this example, it has been described that the notification settings are stored in the server storage unit 220, but it is not limited to this. The notification settings only need to be determined by any device whether to notify the user of the situation when a certain situation occurs, and they may be stored in any of the devices of the terminal device 10, the server device 20, and the communication device 30. Regarding the various types of information described below, as long as the function using the information is satisfied, the information may be stored in any device.

[0035] Figure 4B shows an example of the contact setting screen. The monitoring system 1 provides an emergency notification function for contacting the pre-set contacts with a small number of operations (for example, tapping the icon displayed on the terminal device 10) in an emergency.

[0036] FIG. 4C shows an example of an operation screen of the emergency notification function. When the situation of the above-described notification target occurs, an operation screen (emergency response screen) of the emergency notification function shown in FIG. 4C is displayed on the presentation unit 120 of the terminal device 10. As an example, when three emergency notification destinations are set, emergency notification destination icons P11 to P13 are displayed on the presentation unit 120. The contact information by this emergency notification function can be set by the contact information setting screen shown in FIG. 4B. The user operates the contact information setting screen displayed on the presentation unit 120 of the terminal device 10 to set the contact information. The terminal device 10 stores the set contact information in a storage unit (not shown) of the terminal device 10.

[0037] [Setting of the monitoring mode] FIGS. 5A to 5B are diagrams showing an example of the display for each monitoring mode of the present embodiment. The monitoring system 1 provides a plurality of monitoring modes including a non-disclosure mode and a public mode. FIG. 5A shows an example of a screen displayed on the terminal device 10 in the non-disclosure mode. In the non-disclosure mode, an image of the monitoring target is not displayed, and an image P21 indicating the state of the monitoring target in characters is displayed. FIG. 5B shows an example of a screen displayed on the terminal device 10 in the public mode. In the public mode, an image P22 obtained by the imaging unit 350 of the communication device 30 imaging the monitoring target area A is displayed. At this time, if there is a person to be monitored in the monitoring target area A, a moving image (real-time image) indicating the current situation of the person to be monitored is displayed in the image P22. In FIG. 5B, for convenience of explanation, the moving image of the person to be monitored is represented by a line drawing. In the present embodiment, on the terminal device 10, a moving image of the person to be monitored actually imaged by the imaging unit 350 is displayed instead of a line drawing. The non-disclosure mode and the public mode can be switched by the operation mode switching switch (not shown) of the communication device 30 described above. By making the monitoring system 1 capable of switching the monitoring mode, it is possible to provide a monitoring function that allows the degree of privacy protection and the degree of the monitoring function to be selected according to the relationship between the person to be monitored and the monitor and the situation of the person to be monitored. Next, each function after the initial setting will be described.

[0038] [Monitoring Function (1) Emergency Response Function] FIG. 6 is a diagram showing an example of communication in the emergency response function of the present embodiment. (Step S101) When any abnormality occurs to the person being monitored, the person being monitored operates the emergency button 410 of the remote control device 40. When the remote control device 40 detects that the emergency button 410 has been operated, it transmits first operation information to the communication device 30. The first operation information is information indicating that the emergency button 410 has been operated.

[0039] (Step S102) When the communication device control unit 330 receives information indicating that the emergency button 410 has been operated from the remote control device 40, it transmits the first operation information from the second communication unit 320 to the terminal device 10. In the following description, when the emergency button 410 is operated, the information transmitted by the communication device control unit 330 to the terminal device 10 is also expressed as "first operation information". This expression includes the case where the communication device control unit 330 transfers the first operation information received from the remote control device 40 to the terminal device 10 as it is, and the case where the communication device control unit 330 transmits information generated in response to receiving the first operation information from the remote control device 40 to the terminal device 10.

[0040] Here, when the communication device 30 includes the imaging unit 350, the communication device control unit 330, when receiving the first operation information from the remote control device 40, transmits the image captured by the imaging unit 350 and the first operation information from the second communication unit 320 to the terminal device 10. Also, the communication device 30 may include a communication device sound collection unit 360. In this case, when the communication device control unit 330 receives the first operation information from the remote control device 40, it transmits the information of the sound collected by the communication device sound collection unit 360 and the first operation information to the terminal device 10. Further, the communication device control unit 330 may transmit the information of the sound collected by the communication device sound collection unit 360 without transmitting the image captured by the imaging unit 350. Further, the communication device control unit 330 may transmit both the image captured by the imaging unit 350 and the information of the sound collected by the communication device sound collection unit 360 to the terminal device 10. In addition, when the communication device 30 transmits the image captured by the imaging unit 350 and the sound collected by the communication device sound collection unit 360 immediately after the timing of imaging and sound collection, that is, in real time, it is also referred to as "live view image · voice".

[0041] Hereinafter, it will be described that the communication device 30 includes an imaging unit 350 and a communication device sound collection unit 360 and transmits a live view image · voice to the terminal device 10.

[0042] In addition, the sound in the monitoring target area A can also be collected by a remote control sound collection unit 450 provided in a remote control device 40 operated by a person to be watched over. In this case, the communication device 30 acquires the sound collected by the remote control sound collection unit 450 by transmitting it from the remote control communication unit 430. Here, after the emergency button 410 is operated, the communication between the remote control device 40 and the communication device 30 may be interrupted for some reason. By providing the communication device 30 with the communication device sound collection unit 360, even when the communication between the communication device 30 and the remote control device 40 cannot be established, the communication device 30 can collect the surrounding sound and provide a live view image · voice to the terminal device 10.

[0043] (Step S103) When the terminal device 10 receives the first operation information and the live view image · voice from the communication device 30, the terminal device 10 displays an image indicating that the emergency button 410 has been operated on the presentation unit 120.

[0044] FIG. 7 is a diagram showing an example of a pop-up display during an emergency response in the present embodiment. When the terminal device 10 receives the first operation information from the communication device 30, it displays a pop-up image P31 as shown in FIG. 7. According to the monitoring system 1 configured in this way, even when the user is not operating the terminal device 10 or is performing an operation other than the application of the monitoring system 1, it is possible to notify the user that the person being monitored has operated the emergency button 410.

[0045] FIG. 8 is a diagram showing an example of a live view display in the present embodiment. (Step S104) When the pop-up image P31 displayed in step S103 is operated (for example, tapped), the terminal device 10 displays a live view image P41, a corresponding selection icon P42, and a conversation icon P43. In FIG. 8, for convenience of explanation, the moving image of the person being monitored in the live view image P41 is represented by a line drawing. In the present embodiment, instead of a line drawing, the terminal device 10 displays the actual moving image of the person being monitored captured by the imaging unit 350.

[0046] FIG. 9 is a diagram showing an example of a corresponding selection screen in the present embodiment. (Step S105) When the corresponding selection icon P42 is operated, the terminal device 10 displays the corresponding selection screen P51 shown in FIG. 9.

[0047] Here, the first operation information is an example of event information indicating an event that the emergency button 410 has been operated. The corresponding selection screen P51 includes icons of corresponding contents according to the type of the event. In other words, the event information includes the type of the event, and the presentation unit 120 performs presentation of contents according to the type of the event included in the received event information.

[0048] When the terminal device 10 receives the first operation information, that is, when the type of the event is "operation of the emergency button 410", as an example, the terminal device 10 - The user rushes to the location of the person being watched (icon P511) Report to public institutions (fire, ambulance, police, health center, city hall, etc.) (icon P512) Contact a predefined contact (icon P513) A response selection screen P51 is displayed, which includes various icons such as an icon P514 for starting the telephone application. That is, the response includes at least one of moving the user to the location to be monitored, notifying a public institution, and notifying other users. When any icon on the response selection screen P51 is operated, the terminal device 10 performs an action corresponding to the operated icon (for example, calling a specified contact). Furthermore, the terminal device 10 transmits the selected response content to the server device 20.

[0049] In other words, when the device communication unit 140 receives event information, the presentation unit 120 displays an icon indicating the event information in a pop-up display, and presents content according to the type of event in response to a user operation after the icon is displayed.

[0050] As described above, if the communication device 30 has a judgment unit (not shown) which judges whether or not an abnormality has occurred based on the results of the posture analysis of the person being monitored, the judgment result by the judgment unit that "the person being monitored has fallen" can also be considered an example of event information.

[0051] (Step S106) Returning to Fig. 6, when the server device 20 receives the response content from the terminal device 10, the server device 20 stores the received response content together with the time information transmitted by the terminal device 10 as a response history in the server storage unit 220. In addition, the server device 20 transmits information indicating that the user has responded to the operation of the emergency button 410 to the communication device 30. (Step S107) The communication device 30 releases the emergency state and returns to normal operation.

[0052] [Sharing information with other terminal devices] (Step S108) Other terminal devices 10 (for example, terminal devices 10-2 and 10-3) acquire the corresponding history stored in step S106 from the server device 20.

[0053] Here, the monitoring system 1 provides a function that allows other terminal devices 10 to share the selection result of the corresponding content selected in step S105. For example, when the terminal device 10 that selects the corresponding content in step S105 is the terminal device 10-1, other terminal devices 10 (for example, terminal devices 10-2 and 10-3) can acquire the selection result (that is, the corresponding content of the user of the terminal device 10-1 for the operation of the emergency button 410).

[0054] That is, the event information is transmitted to a plurality of users, and the presentation unit 120 presents the status of the response to the event information by any one of the plurality of users.

[0055] FIG. 10 is a diagram showing an example of the display screen of the corresponding history of the present embodiment. The terminal device 10 displays the corresponding history screen P61 acquired from the server device 20. This corresponding history screen P61 includes the name of the corresponding user, the corresponding time, and the corresponding content.

[0056] In other words, the presentation unit 120 of the terminal device 10 presents a screen (corresponding selection screen P51) for selecting a plurality of corresponding items, and presents the content of the corresponding item selected by any one of the plurality of users.

[0057] As described above, a plurality of destination terminal devices 10 can be set for one communication device 30. In this case, when the communication device 30 receives event information (for example, first operation information) from the remote control device 40, it transmits the event information to each of the plurality of set terminal devices 10. At this time, by sharing among the users of the plurality of terminal devices 10 that a user of any one of the terminal devices 10 has taken some action with respect to the event information (for example, having rushed to the location where the person under watch is, in response to the operation of the emergency button 410), each user can determine whether further action is necessary. According to the monitoring system 1 configured in this way, a sense of security can be given to the users.

[0058] [Video display during emergency button operation] In addition, the monitoring system 1 may provide a function of displaying, on the video display screen P62 shown in FIG. 10, the images captured by the imaging unit 350 in the time periods before and after the operation of the emergency button 410.

[0059] FIG. 11 is a diagram showing another example of communication in the emergency response function of the present embodiment. (Step S101) As described with reference to FIG. 6, when some abnormality occurs to the person under watch, the person under watch operates the emergency button 410 of the remote control device 40. When the remote control device 40 detects that the emergency button 410 has been operated, it transmits first operation information to the communication device 30.

[0060] (Step S201) The communication device 30 of the present embodiment always performs imaging by the imaging unit 350 and sound collection by the communication device sound collection unit 360, regardless of whether the emergency button 410 is operated. The communication device control unit 330 stores the captured images and the collected sounds in the communication device storage unit 390. Depending on the capacity of the communication device storage unit 390, the communication device control unit 330 may delete the information captured and collected more than a predetermined period in the past and store new images and sounds. Here, the predetermined period is, for example, 12 hours, 24 hours, or 7 days, etc. (Step S202) When the operation of the emergency button 410 is detected in step S101, the communication device 30 stores, based on a predetermined recording time, in the communication device storage unit 390, among the past images and sounds stored in the communication device storage unit 390, the images and sounds in the most recent period, and the images and sounds captured and recorded after the operation of the emergency button 410 is detected. For example, when the predetermined recording time is 10 minutes, the communication device 30 stores in the communication device storage unit 390 the images and sounds for 5 minutes before and 5 minutes after the operation of the emergency button 410 is detected.

[0061] (Step S203) The terminal device 10 requests the communication device 30 for the images and voices before and after the operation of the emergency button 410 is detected. For example, the user taps the playback button image on the video display screen P62 shown in FIG. 10. When the terminal device 10 detects the tap on the playback button image of the video display screen P62, the terminal device 10 requests the communication device 30 for the images and voices before and after the operation of the emergency button 410 is detected. (Step S204) When the communication device 30 receives a request for the images and voices before and after the operation of the emergency button 410 is detected, the communication device 30 transmits to the terminal device 10 the images and sounds in the time period before and after the operation of the emergency button 410 is detected, which were saved in step S202. (Step S205) When the terminal device 10 receives the images and sounds in the time period before and after the operation of the emergency button 410 is detected from the communication device 30, the terminal device 10 plays back the received images and sounds.

[0062] The information indicating the operation of the emergency button 410 (first operation information) is an example of event information. The event information includes information indicating a video in a time range including the occurrence time of the event, and the presentation unit 120 presents the video. Here, the time range including the occurrence time of the event is, for example, 10 minutes, which is 5 minutes before and 5 minutes after the operation of the emergency button 410 described above. Note that the time width and the front-back ratio shown here are examples, and it may be longer or shorter than 10 minutes, and the front-back time ratio may be an equal ratio or an unequal ratio where the front (or back) is longer. Also, the information indicating the video may be the video file itself or link information indicating the storage location of the video.

[0063] According to the monitoring system 1 configured as described above, it is possible to present to the terminal device 10 the situation before the operation of the emergency button 410, that is, the situation in the time period when the cause leading to the operation of the emergency button 410 occurred. For this reason, the user can grasp the cause of the abnormality that occurred to the person under surveillance and can take a more appropriate response.

[0064] [Emergency Button Operation History Display] FIG. 12 is a diagram showing an example of the event history display of the present embodiment. As described above, the terminal device 10 includes a presentation unit 120 and a terminal communication unit 140. The terminal communication unit 140 receives event information regarding an event that occurred at the location to be monitored. This event information includes, as an example, first operation information indicating that the emergency button 410 has been operated. The presentation unit 120 presents the history of the event information received by the terminal communication unit 140. As an example, the presentation unit 120 of the terminal device 10 displays, on the event history screen P71, the events that occurred in the past among the events to be notified, together with their occurrence dates and times. According to the monitoring system 1 configured as described above, not only can a notification be made at the timing of the occurrence of an event (for example, the operation of the emergency button 410), but also the events that occurred in the past can be presented to the user. Further, the terminal device 10 may have a function of excluding (that is, deleting) the events selected by the user from the display targets among the event history. Further, the terminal device 10 may display the occurrence timing of the event in a calendar format, or may display the detailed information of the events that occurred on the date selected from the calendar.

[0065] Here, the event information includes the occurrence time of the event. The presentation unit 120 presents the history of the event information based on the occurrence time of the event. Here, the presentation unit 120 can also be configured to present the history of the event information based on the arrival time of the event information at the terminal device 10. However, since the event information is transmitted from the remote control device 40 to the terminal device 10 via the communication device 30 and the server device 20, there may be a deviation between the arrival time of the event information and the occurrence time of the event depending on the communication situation or the like. Also, for example, when a plurality of events occur, the occurrence order of the events and the arrival order of the event information may be interchanged. According to the monitoring system 1 configured to present the history of the event information based on the occurrence time of the event as in the present embodiment, the occurrence history of the event can be presented more accurately regardless of the communication situation.

[0066] Also, as described above, in the monitoring target area A, the communication device 30 including the imaging unit 350 is installed. The event information transmitted to the terminal device 10 (in the above example, the information indicating that the emergency button 410 has been operated. That is, the first operation information) includes the information of the image captured by the imaging unit 350 (for example, a thumbnail image or a moving image). The presentation unit 120 presents this image information.

[0067] Also, the terminal device 10 may attach an unopened display P72 to an event in the event history shown on the event history screen P71 that the user has not confirmed the content, that is, an unopened event. That is, the presentation unit 120 may present that the event information has not been browsed by the user.

[0068] Also, for an unopened event, when a predetermined time has elapsed since the event occurred, the terminal device 10 may notify the user that the predetermined time has elapsed by changing the color of the unopened display P72, displaying a pop-up image, making a sound, vibrating, or the like. That is, the presentation unit 120 presents that a predetermined time has elapsed since the event information has not been browsed by the user.

[0069] In addition, the terminal device 10 may change the color, shape, etc. of the unopened display P72 according to the type of event. That is, the presentation unit 120 may perform different presentations according to the type of event indicated by the event information.

[0070] FIG. 13 is a diagram showing an example of a selection screen for an event to be presented in this embodiment. The terminal device 10 may narrow down notifications when an event occurs based on a user's setting operation on the event selection screen P81. The presentation unit 120 selects event information to be presented based on at least one of the occurrence time of the event and the type of the event.

[0071] According to the monitoring system 1 configured as described above, it is easy for the user to grasp the situation at the time of the occurrence of the event, and the user can take a more appropriate response to the event.

[0072] [Conversation function using the remote control device for the watching function (2)] The monitoring system 1 provides a conversation function using the remote control device 40. For example, by the user tapping the conversation icon P43 shown in FIG. 8 described above, a conversation can be conducted between the user and the person being watched.

[0073] As described above, the remote control device 40 includes a remote control sound collection unit 450. When there is a conversation request from the terminal device 10, the communication device control unit 330 transmits the sound information collected by the remote control sound collection unit 450 to the terminal device 10 based on the second operation information. Here, the second operation information is information indicating that there has been an operation on the OK button 420. That is, when the remote control device 40 detects an operation on the OK button 420, it transmits the second operation information. A more specific procedure of the conversation function will be described.

[0074] FIG. 14 is a diagram showing an example of communication of the conversation function in this embodiment. (Step S301) When the terminal device 10 detects a tap on the conversation icon P43, it transmits a conversation request to the communication device 30. (Step S302) When the communication device 30 receives a conversation request from the terminal device 10, the communication device sound output unit 370 outputs a conversation request sound. The person being monitored hears the conversation request sound and knows that there is a request for conversation, and determines whether to permit the conversation. When the person being monitored permits the conversation, the OK button 420 of the remote control device 40 is operated. (Step S303) When the remote control device 40 detects an operation on the OK button 420, the remote control device 40 notifies the terminal device 10 of information indicating that there has been an operation on the OK button 420 via the communication device 30 and the server device 20. Here, the information indicating that there has been an operation on the OK button 420 is also referred to as second operation information. That is, when the remote control device 40 detects an operation on the OK button 420, the remote control device 40 transmits the second operation information.

[0075] (Step S304) When the terminal device 10, the server device 20, the communication device 30, and the remote control device 40 detect that the conversation request has been permitted in Step S303, they start a two-way call. Here, the two-way call function is a function that enables two-way conversation between the user and the person being monitored by causing the sound picked up by the terminal sound input unit 150 of the terminal device 10 to be output from the communication device sound output unit 370 of the communication device 30 and causing the sound picked up by the remote control sound input unit 450 of the remote control device 40 to be output from the terminal sound output unit 160 of the terminal device 10. In the two-way call function, the monitoring system 1 may cause the terminal device 10 to display an image of the person being monitored during the call captured by the imaging unit 350. (Step S305) The communication device 30 captures an image of the monitoring target area A by the imaging unit 350. (Step S306) The remote control device 40 picks up the voice of the person being monitored by the remote control sound input unit 450. (Step S307) The remote control device 40 transmits the picked-up voice to the communication device 30 as voice information. (Step S308) The communication device 30 transmits the image captured in Step S305 and the voice information received from the remote control device 40 in Step S307 to the terminal device 10. (Step S309) The terminal device 10 presents the image and audio received from the communication device 30 to the user. (Step S310) In parallel with Steps S305 to S309, the terminal device 10 transmits the audio picked up by the terminal microphone unit 150 to the communication device 30 as audio information. (Step S311) The communication device 30 receives the audio information from the terminal device 10 and emits sound from the communication device speaker unit 370.

[0076] According to the monitoring system 1 configured as described above, since the remote control microphone unit 450 of the remote control device 40 carried by the person under surveillance is used to pick up the voice of the person under surveillance, for example, compared with the case of picking up the voice using the communication device microphone unit 360 of the communication device 30, the voice can be picked up clearly. Further, according to the monitoring system 1, since the communication device speaker unit 370 of the communication device 30 is used to emit sound, for example, compared with the case of emitting sound using the remote control speaker unit 460 of the remote control device 40, a louder sound or a sound with better sound quality can be emitted. Therefore, according to the monitoring system 1, the quality of the conversation between the user and the person under surveillance can be improved.

[0077] As described above, the remote control device 40 includes an OK button 420. This OK button 420 is an operation button different from the emergency button 410. The remote control device 40 transmits second operation information indicating the operation of the OK button 420. The communication device control unit 330 of the communication device 30 controls the type of information transmitted to the terminal device 10 based on receiving the second operation information from the remote control device 40. In the case of the above example, when the OK button 420 is operated, the communication device control unit 330 controls the type of information transmitted to the terminal device 10 so as to transmit an image and audio to the terminal device 10.

[0078] [Monitoring function (3) Live view function] The monitoring system 1 provides a live view function for presenting the current image and sound of the monitoring target area A to the terminal device 10 in real time. In the live view function, the terminal device 10 displays, for example, the live view image P41 shown in FIG. 8 described above. In the above-described conversation function, the remote control sound collection unit 450 of the remote control device 40 collects sound. However, in the live view function, the communication device sound collection unit 360 of the communication device 30 collects sound, which is different. Also, the live view function has different operations in the non-disclosure mode and the disclosure mode. In the case of the non-disclosure mode, a permission procedure by the person being monitored is required. Hereinafter, an example of the procedure will be described.

[0079] <Live View Function: Non-disclosure Mode> FIG. 15 is a diagram showing an example of communication of the live view function in the non-disclosure mode of the present embodiment. (Step S401) When the terminal device 10 detects an operation by the user to request the live view function (for example, selection of the "Live" tab or selection of the "Current Status" tab), the terminal device 10 transmits a live view request to the communication device 30. (Step S402) When the communication device 30 receives the live view request from the terminal device 10, the communication device sound output unit 370 outputs a live view request sound. The person being monitored hears the live view request sound and knows that there is a request for the live view, and determines whether to permit the live view. When the person being monitored permits the live view, the OK button 420 of the remote control device 40 is operated. (Step S403) When the remote control device 40 detects an operation on the OK button 420, the remote control device 40 notifies the terminal device 10 of information indicating that there has been an operation on the OK button 420 via the communication device 30 and the server device 20. Here, the information indicating that there has been an operation on the OK button 420 is also referred to as second operation information. That is, when the remote control device 40 detects an operation on the OK button 420, the remote control device 40 transmits the second operation information. In the above-described conversation function as well, the remote control device 40 transmits the second operation information. Depending on the requested function, the meaning of the operation of the OK button 420, that is, the meaning of the second operation information, changes.

[0080] (Step S404) The communication device 30 captures the monitoring target area A by the imaging unit 350. Also, the communication device 30 picks up the sound of the monitoring target area A by the communication device sound collection unit 360. (Step S405) The communication device 30 transmits the image and the audio information to the terminal device 10. (Step S406) The terminal device 10 presents the image and the audio received from the communication device 30 to the user.

[0081] <Live View Function: Public Mode> FIG. 16 is a diagram showing an example of communication of the live view function in the public mode of the present embodiment. In the public mode, the communication device 30 constantly captures the monitoring target area A by the imaging unit 350.

[0082] (Step S501) When the terminal device 10 detects an operation in which the user requests the live view function (for example, selection of the "Live" tab or selection of the "Current Status" tab), the terminal device 10 transmits a live view request to the communication device 30. (Step S502) When the communication device 30 receives the live view request from the terminal device 10, the communication device sound output unit 370 emits a live view request sound. The person being monitored hears the live view request sound and knows that there is a live view request, and determines whether to permit the live view. When the person being monitored permits the live view, the OK button 420 of the remote control device 40 is operated. (Step S503) When the remote control device 40 detects an operation on the OK button 420, the remote control device 40 notifies the terminal device 10 of information indicating that there has been an operation on the OK button 420 via the communication device 30 and the server device 20.

[0083] (Step S504) The communication device 30 picks up the sound of the monitoring target area A by the communication device sound collection unit 360. (Step S505) The communication device 30 transmits the image and the audio information to the terminal device 10. (Step S506) The terminal device 10 presents the image and the audio received from the communication device 30 to the user.

[0084] The live view request is also referred to as an image transmission request. That is, when an image transmission request is received from the terminal device 10, the communication device control unit 330 of the communication device 30 transmits the image captured by the imaging unit 350 to the terminal device 10 based on the second operation information.

[0085] Here, differences in the operation of the monitoring system 1 between the public mode and the non - public mode will be described with reference to the drawings.

[0086] FIG. 17 is a diagram showing an example of the operation of the monitoring system 1 in the public mode and the non - public mode of the present embodiment. In FIG. 17, "OFF" indicates a state where the button is not operated, and "ON" indicates a state where the button is operated. Regarding images, in the public mode, the image captured by the imaging unit 350 is presented to the terminal device 10 regardless of the operation of the emergency button 410 and the OK button 420. On the other hand, in the non - public mode, when the emergency button 410 is operated, or when the OK button 420 is operated in response to a conversation request or a live view request (that is, when the person being monitored gives permission), the image captured by the imaging unit 350 is presented to the terminal device 10. That is, in the non - public mode, when neither the emergency button 410 nor the OK button 420 is operated (OFF state), the image is not presented. Regarding audio, in both the public mode and the non - public mode, when the emergency button 410 is operated, or when the OK button 420 is operated in response to a conversation request or a live view request (that is, when the person being monitored gives permission), the recorded audio is presented to the terminal device 10. That is, regarding audio, in both the public mode and the non - public mode, when neither the emergency button 410 nor the OK button 420 is operated (OFF state), it is not presented.

[0087] Regarding the audio, in both the public mode and the non - public mode, when the emergency button 410 is operated, the communication device sound collection unit 360 of the communication device 30 presents the sound collected. Also, in both the public mode and the non - public mode, when the OK button 420 is operated (that is, when the person being monitored gives permission), in the case of a conversation request, the sound collected by the remote control sound collection unit 450 is presented, and in the case of a live view request, the sound collected by the communication device sound collection unit 360 is presented.

[0088] As described above, the information indicating the operation of the OK button 420, that is, the second operation information, changes its meaning depending on the content of the user's request and the operation mode. The second operation information is information indicating an operation that permits providing at least one of the information of the sound collected and the image captured to the terminal device 10 in the non - public mode where the image captured by the imaging unit 350 is not made public.

[0089] Also, the second operation information is information indicating an operation that permits providing the information of the sound collected to the terminal device 10 in the public mode where the image captured by the imaging unit 350 is made public.

[0090] [Monitoring function (4) Voltage drop notification function of the remote control device] FIG. 18 is a diagram showing an example of communication in the voltage drop notification function of the present embodiment. (Step S601) The voltage detection unit 470 of the remote control device 40 detects the power supply voltage of the remote control device 40. When the detected power supply voltage is equal to or lower than a predetermined value, the remote control control unit 440 transmits a voltage drop notification to the terminal device 10. That is, when the communication device control unit 330 receives voltage drop information from the remote control device 40, it transmits information indicating that the power supply voltage of the remote control device 40 has dropped to the terminal device 10. (Step S602) The terminal device 10 receives the voltage drop notification. (Step S603) The terminal device 10 notifies the user of the voltage drop.

[0091] FIG. 19 is a diagram showing an example of a voltage drop notification screen according to the present embodiment. In step S603, the terminal device 10 displays a voltage drop notification screen P91 shown in FIG. 19. When the power supply voltage is restored by battery replacement or charging of the remote control device 40, the remote control device 40 may transmit a voltage restoration notification to the communication device 30 or the terminal device 10. The communication device 30 and the terminal device 10 may manage the period during which the power supply voltage of the remote control device 40 drops from the time when the voltage drop notification is received until the voltage restoration notification is received.

[0092] [Monitoring function (5) Remote control device search function] When the monitoring system 1 cannot find the remote control device 40, it provides a remote control device search function that makes the remote control device 40 emit a sound to assist in searching for the remote control device 40.

[0093] FIG. 20 is a diagram showing an example of communication in the remote control device search function according to the present embodiment. (Step S701) The communication device 30 is provided with a remote control device search switch (not shown). The communication device 30 detects an operation of the remote control device search switch. This remote control device search switch is an example of an operation reception unit that receives an operation to search for the remote control device 40. (Step S702) When the operation of the remote control device search switch is detected, the communication device 30 transmits a remote control device search instruction to the remote control device 40. (Step S703) When the remote control device 40 receives the remote control device search instruction from the communication device 30, it emits a sound from the remote control sound generation unit 460 to notify the location to the person being monitored or the user.

[0094] The remote control device 40 may be provided with a vibration unit (not shown) and a light emission unit (not shown), and may notify its location by vibration or light when it receives a remote control device search instruction from the communication device 30.

[0095] [Monitoring function (6) Remote control device out-of-range notification function] The monitoring system 1 provides a function of notifying the terminal device 10 when the remote control device 40 is outside the communication range of the communication device 30.

[0096] FIG. 21 is a diagram showing an example of communication in the function of notifying that the remote control device is outside the range in the present embodiment. (Step S801) The communication device 30 determines whether communication with the remote control device 40 is possible. Note that the communication device 30 may perform the determination of communication availability regularly or in response to a request from the terminal device 10. When the communication device 30 cannot communicate with the remote control device 40, it determines that the remote control device 40 is outside the communication range and transmits remote control out-of-range information to the terminal device 10. Note that the communication device 30 may determine that the remote control device 40 is outside the communication range in a case where the power supply voltage of the remote control device 40 has not decreased and communication with the remote control device 40 is impossible, by combining with the above-described function of notifying a decrease in the voltage of the remote control device.

[0097] (Step S802) The terminal device 10 receives remote control out-of-range information from the communication device 30. (Step S803) The terminal device 10 presents to the user that the remote control device 40 is outside the communication range of the communication device 30.

[0098] As described above, according to the monitoring system 1, it is possible to provide a highly convenient monitoring system for both the monitor and the non-monitor.

[0099] Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and appropriate changes can be made without departing from the spirit of the present invention.
