The information detection device 2 is provided, and bedding on which the care recipient sleeps is laid.
Further, as shown in FIG. 3 (iii), in the bed 8, a drive unit (not shown) operates by operating the upper and lower buttons of the operation switch, and in response to this operation, the floor plate 82 (bed movable portion) on the upper body side. Is tilted so that the care recipient lying on the bed 8 can raise or lower his / her back. That is, the bed 8 has a floor plate 82 as a bed movable portion whose inclination can be changed with respect to the bed frame 81.

Receive via.

The tilt sensor 21 includes, for example, a gyroscope or an acceleration sensor.
The tilt sensor 21 detects a component of gravitational acceleration (gravitational acceleration vector value g') in a direction orthogonal to the floor plate 82 surface (see FIGS. 1 and 3 (iii)), and uses this as information regarding the tilt of the movable bed portion. Is transmitted to the monitoring device 1.
As a result, in the monitor device 1, the external sensor information receiving unit 11 receives the information regarding the inclination (gravitational acceleration vector value g').
In the monitoring device 1, the floor plate is based on the relationship (g'= gcosθ) between the gravitational acceleration g acquired in the state where the floor plate 82 is not tilted in advance and the gravitational acceleration vector value g'actually detected by the tilt sensor 21. The inclination angle θ of 82 can be obtained (see FIG. 3 (iii)).
By this inclination angle θ, the state of the posture (posture of the upper body) of the care recipient in the bed 8 can be specified.
The tilt sensor 21 can also be attached to another movable portion. For example, when the portion of the floor plate 82 corresponding to the lower leg is a movable portion that can be tilted, by attaching the tilt sensor 21 to the floor plate portion that is the movable portion, it is specified how much the floor plate portion is tilted. be able to.

The biosensor 22 detects a relatively small pressure in the airbag 221 and the airbag 221 whose internal pressure fluctuates in response to an external action, and generates an electric signal corresponding to this pressure as biometric information. It consists of.
The airbag 221 is arranged on the floor plate 82 at a position corresponding to the chest of the care recipient lying on the bed 8, and the pressure detection unit 222 is provided in the housing of the information detection device 2. Velcro (registered trademark) is provided on the back surface of the airbag 221 and the front surface of the floor plate 82 of the bed 8, so that the airbag 221 can be fixed to the floor plate 82 via the magic tape (registered trademark). There is.
According to the biosensor 22, minute vibrations (microbody movements) associated with the heartbeat and respiration of the care recipient lying on the bed 8 can be detected, and an electric signal indicating a pressure value corresponding to the microbody movements can be generated. It can be transmitted to the monitoring device 1 as biological information.
As a result, the monitoring device 1 receives the biometric information of the care recipient lying on the bed 8 and acquires the heart rate and respiratory rate of the care recipient based on the biometric information, or is based on the heart rate and respiratory rate. It becomes possible to identify the sleeping state of the care recipient.

The load sensor 23 uses the airbag 221 used for the biological sensor 22 to detect a relatively large pressure (load) in the airbag 221 and generate an electric signal corresponding to the load.
According to the load sensor 23, it is possible to detect a relatively large vibration (coarse body movement) accompanying entering or leaving the bed, and transmitting an electric signal indicating a load value corresponding to the rough body movement to the monitor device 1. Can be done.
As a result, on the monitor device 1 side, it is possible to determine whether the care recipient has entered or left the floor based on the change in the presence or absence of the load value from the load sensor 23, and the load value above a certain level is continuously received. This makes it possible to determine the presence of the care recipient.
Further, in the case of being in bed, the load value differs depending on the distance between the load sensor 23 and the care recipient, so that the bed position of the care recipient can be specified according to the load value.

The internal sensor 12 includes, for example, a temperature sensor, a humidity sensor, an illuminance sensor, and the like, and is provided inside the main body of the monitor device 1.
According to the internal sensor 12, environmental information such as temperature, humidity, and illuminance around the bed 8 can be detected.
It is also possible to provide each sensor constituting the internal sensor 12 outside the main body of the monitor device 1 and receive the information detected from each sensor via the external sensor information receiving unit 11.

The wireless communication unit 13 has a function corresponding to the output means of the present invention. Specifically, the monitor device 1 is provided with an antenna (not shown) that transmits a predetermined radio wave, and the wireless communication unit 13 is a terminal device located within a predetermined range (receivable area) in which the radio wave can be received. Information is output to 4 via wireless communication.
More specifically, the wireless communication unit 13 is a communication interface of a wireless LAN (Wi-Fi: registered trademark) corresponding to the IEEE802.11 standard (referring to a general standard of wireless LAN including IEEE802.11b / g and the like). Therefore, Wi-Fi connection and communication can be performed with the terminal device 4.

For example, as shown in FIG. 8 (i), the wireless communication unit 13 periodically transmits a packet called a beacon to the surroundings, and in this state, the terminal device 4 located in the receivable area transmits the beacon. I am making it possible to receive. The terminal device 4 makes a connection request to the monitor device 1 based on the SSID included in the received beacon, and the monitor device 1 makes a connection response to the connection request.
As a result, a data link capable of bidirectional data communication (Wi-Fi communication) is established between the monitor device 1 and the terminal device 4.
The wireless communication unit 13 of the present embodiment does not use the data link established by such a Wi-Fi connection, but uses a beacon transmitted to the surroundings prior to the Wi-Fi connection to communicate with the terminal device 4. I try to pass various information.

Specifically, as shown in FIG. 8 (ii), various information is set as an SSID, and this SSID is included in the beacon and transmitted, so that the SSID included in the beacon is used in the terminal device 4 that has received the beacon. Various information is displayed based on this.
The beacon is transmitted, for example, at intervals of 100 milliseconds, as a receivable area in a concentric range having a line-of-sight of about 100 m centered on the monitor device 1.
Therefore, the terminal device 4 can immediately receive the information output from the monitor device 1.
Further, the terminal device 4 can exchange information only by being located in the beacon receivable area.
For example, the terminal device 4 can output information regarding the inclination of the floor plate 82 of the bed 8 in a place where the bed 8 is difficult or impossible to see.

The timekeeping unit 14 measures time information such as a date, a time, and an elapsed time.

The data stored in the storage unit 15 includes the care recipient registration table shown in FIG. 4, the inclination determination condition table shown in FIG. 5, the brightness determination condition table shown in FIG. 6, and the sleep state transition shown in FIG. 7 (i). Information, analysis information shown in FIG. 7 (ii), and the like.

The control unit 16 is composed of a computer including a CPU, ROM, and RAM, and performs various control operations.
Specifically, information that can identify the long-term care recipient is requested and transmitted to the terminal device 4.
For example, in the above-mentioned normal Wi-Fi connection operation (see FIG. 8 (i)), as shown in FIG. 8 (ii), information or the like that can identify the state of the care recipient is set in the SSID, and this is set. Performs the operation of including in the beacon and transmitting.

As shown in FIG. 9 (i), the SSID is identification information consisting of up to 32 digits of alphanumeric characters and symbols that form a part of the beacon, and its contents can be changed.
In the present embodiment, in the 12th to 32nd digits (message part) of the SSID, fluctuation information that fluctuates according to the condition and environment of the care recipient is set.
In the 1st to 11th digits, the monitoring device management number and the name of the care recipient are set with reference to the care recipient registration table t1 (see FIG. 4) stored in the storage unit 15.

As shown in FIG. 9 (ii), the fluctuation information includes, for example, identification information that can identify the bed state and sleep state, environmental information, information on inclination, information on brightness, sleep depth, and timing of transition to deep sleep. , Identification information that can identify the transition timing to light sleep, identification information that can identify the presence or absence of body movement, and biometric information, each of which can be set at a predetermined timing (for example, every time a beacon is transmitted). it can. The setting method of each fluctuation information will be described below.

Regarding the state of being in bed, the control unit 16 determines “entering the floor”, “being in bed”, and “getting out of bed” based on the load value detected by the load sensor 23.
For example, if a load value of a predetermined value or more is detected, it is determined as "entering the floor", and if a load value of a predetermined position or more is continuously detected, it is determined as "being in bed" and the value is equal to or more than the predetermined value. If the load value is no longer detected, it is determined to be "getting out of bed".
If it is determined to be "in bed", the identification information "1" is set in the 12th digit of the SSID, and if it is determined to be "getting out of bed", the identification information "0" is set.

Regarding the sleep state, the control unit 16 determines whether it is “sleeping” or “awakening” based on the biological information received from the biological sensor 22.
For example, when a unique heartbeat / respiration indicating sleep is detected in the biometric information received from the biosensor 22, it is determined to be "sleeping", and otherwise it is determined to be "awakening".
If it is determined to be "sleeping", the identification information "0" is set in the 13th digit of the SSID, and if it is determined to be "awakening", the information is not set.

For the temperature, humidity, and illuminance, the respective information detected by the temperature sensor, the humidity sensor, and the illuminance sensor, which are the internal sensors 12, is set.
For example, the control unit 16 sets temperature information in the 14th to 15th digits of the SSID, humidity information in the 16th to 17th digits, and illuminance information in the 18th to 20th digits.

Regarding the information regarding the inclination, the control unit 16 operates as the inclination determination means, and based on the information regarding the inclination of the bed movable portion (floor plate 82) received from the inclination sensor 21 and the information regarding the preset period. It is determined whether or not the inclination determination condition is satisfied.
The “information on the inclination of the movable bed portion” is the inclination angle θ of the floor plate 82 of the bed 8, and can be obtained based on the gravitational acceleration vector value detected by the inclination sensor 21.
The “presettable period information” is, for example, a night time zone in which the care recipient is considered to be sleeping, and can be preset by a predetermined operation.
The “tilt determination condition” is a condition shown in the inclination determination condition table t2 shown in FIG. 5, and the control unit 16 controls the control unit 16 in the time zone (21:00 to 6:00) set in the “set time” column. , When the inclination angle θ of the floor plate 82 equal to or larger than the angle (5 °) set in the “bed inclination” column is detected, it is determined that the condition is satisfied. That is, in this case, it can be determined that some problem has occurred, such as the floor plate 82 of the bed 8 being slanted for some reason and the care recipient cannot restore it.
Then, when it is determined that the inclination determination condition is satisfied by the determination by the inclination determination means, the control unit 16 sets the identification information "1" in the 21st digit of the SSID as the information regarding the inclination. As a result, the wireless communication unit 13 includes the SSID in which the information regarding the inclination is set in the beacon and transmits the SSID.
That is, the wireless communication unit 13 outputs information on the inclination when it is determined by the inclination determination means that the inclination determination is established.
Thereby, on the terminal device 4 side, it is possible to identify the care recipient in a state where the inclination of the bed 8 is abnormal.
In consideration of the fact that the sleep time zone and the posture during sleep are different for each long-term care recipient, the "set time" and "bed tilt" are set differently for each long-term care recipient in the inclination determination condition table t2. You can also do it.
Further, as information on the inclination, the inclination angle θ of the floor plate 82 can be set in the SSID. In this way, the state of the bed 8 of each long-term care recipient can always be grasped.

With respect to the information regarding the brightness, the control unit 16 operates as the brightness determination means, and whether or not the brightness determination condition is satisfied based on the information regarding the brightness around the bed and the information regarding the preset period. Is determined.
The "information on the brightness around the bed" is, for example, the illuminance detected by the illuminance sensor which is the internal sensor 12.
The “presettable period information” is, for example, a night time zone in which the care recipient is considered to be sleeping, and can be preset by a predetermined operation.
The “brightness determination condition” is a condition shown in the brightness determination condition table t3 shown in FIG. 6, and for example, regarding the uppermost condition, the control unit 16 sets the care recipient in the “name” column. Regarding (Tetsuji Yamada), in the time zone (21:00 to 6:00) set in the "set time" column, illuminance equal to or higher than the illuminance (300 Lx) set in the "set illuminance" column was detected. In that case, it is determined that the condition is satisfied. That is, in this case, it can be determined that a problem such as forgetting to turn off the lighting has occurred.
Then, when it is determined that the brightness determination condition is satisfied by the determination by the brightness determination means, the control unit 16 sets the identification information "1" in the 22nd digit of the SSID as the information regarding the brightness.
Thereby, on the terminal device 4 side, it is possible to identify the care recipient in a state where the brightness of the room is abnormal.
The illuminance can also be set to SSID as information on brightness. By doing so, it is possible to always grasp the brightness of the surroundings of each long-term care recipient.

Regarding the sleep depth, the control unit 16 determines whether the long-term care recipient is light sleep or deep sleep based on the biological information detected by the biological sensor 22.
Specifically, when information on the specific heartbeat / respiration corresponding to light sleep (REM sleep) is detected in the biological information, it is determined as "light sleep" and the unique heartbeat / breathing corresponding to deep sleep. When information on respiration is detected, it is judged as "deep sleep".
Then, the control unit 16 sets the identification information "0" in the 23rd digit of the SSID when it is determined to be a light sleep, and sets the identification information "1" when it is determined to be a "deep sleep".

The timing of transition to deep sleep and the timing of transition to light sleep can be determined based on the sleep rhythm analyzed by the transition of the sleep state of the care recipient.
By the way, the timing of transition to deep sleep and the timing of transition to light sleep are important information for providing long-term care at an appropriate timing.
This is because the care recipient may need assistance such as turning over or changing diapers even while sleeping. In this case, it is less burdensome for the care recipient to provide assistance in a light sleep state. This is because it is recommended.
In other words, if the care recipient is currently in a light sleep state (care period), care must be provided before the transition to deep sleep, and if the care recipient is currently in a deep sleep state, the following After knowing the long-term care period, it is possible to prepare for long-term care and perform tasks other than long-term care, so that long-term care can be performed efficiently while minimizing the burden on the long-term care recipient.

Therefore, for example, as shown in FIG. 7 (i), the control unit 16 sets the time when the person enters the bed → the time when the person falls asleep (the time when the state shifts to the REM sleep state (first time)) → the non-REM sleep (first time). ) → Time of transition to REM sleep (2nd time) → Time of transition to non-REM sleep (2nd time) → Time of transition to REM sleep (3rd time) → ・ ・ ・ → Time of waking up → Time of getting out of bed Such a transition of the sleep state is extracted for each care recipient and stored in the storage unit 15 as sleep state transition information.
Then, based on this sleep state transition information, the sleep rhythm of the care recipient is analyzed.
For example, as shown in FIG. 7 (ii), the time from falling asleep to falling asleep (first REM sleep) (sleeping time), the time from falling asleep to non-REM sleep (first REM sleep), non-REM Obtain the time of sleep (first time), the time from entering the bed to REM sleep (second time), the time of REM sleep (second time), etc., and accumulate these for a certain period (for example, one week or one month). And find the average value.
According to such analysis information, it is possible to specify the transition timing of each of REM sleep and non-REM sleep, which is alternately repeated a plurality of times at predetermined time intervals in one sleep, for each care recipient.

Then, by operating as the target person information control means, the control unit 16 transmits the target person information in which the information regarding the timing of transition to deep sleep and other information regarding the target care recipient that can be set in advance are associated with the terminal device 4 It is possible to output at.
Specifically, the control unit 16 identifies the current sleep depth of the care recipient based on biological information, and when the person is in a light sleep, calculates the time until the person shifts to a deep sleep.
For example, when the current sleep depth of the care recipient is non-REM sleep (first time), the elapsed time Ta from the transition to non-REM sleep (first time) to the present is obtained, and the analysis information (FIG. 7 (FIG. 7). The time (average value) Tb of non-REM sleep (first time) can be taken out from (ii)), and the time obtained by subtracting Ta from Tb can be obtained as the time until transition to deep sleep.
For example, the control unit 16 sets the identification information "1" in the 24th digit of the SSID when the time until the transition to deep sleep is within 10 minutes, and sets the identification information "0" when the time is within 30 minutes. To do.
Thereby, on the terminal device 4 side, the timing at which the long-term care possible period ends can be specified.
Further, the control unit 16 obtains the time until the transition to the light sleep by the same method when the current sleep state is deep sleep, and if it is within 10 minutes, the identification information "1" is input to the 25th digit of the SSID. Set.
Thereby, on the terminal device 4 side, it is possible to specify the timing at which the long-term care possible period is started next.
It is also possible to set the time information and the time zone in the SSID as the timing (information about the care timing) to shift to a light sleep or a deep sleep. As a result, it is possible to accurately grasp the care timing, grasp the care timing that occurs a plurality of times, and utilize it for care.

Regarding the body movement, the control unit 16 can determine from the load sensor 23 whether or not the care recipient has body movement based on the load value and the change in the load value.
When the control unit 16 determines that there is body movement, the control unit 16 sets the identification information "1" in the 26th digit of the SSID.

The biological information corresponds to the heart rate and the respiratory rate that can be obtained based on the biological information detected by the biological sensor 22.
The control unit 16 sets the heart rate in the 27th to 28th digits of the SSID and the respiratory rate in the 29th to 30th digits.

By the way, the control unit 16 can perform an operation of processing information related to biological information as a processing means.
For example, the detection threshold value is stored in the storage unit 15 by setting in advance, and only the information included in the detection threshold value is extracted from the biometric information acquired from the biosensor 22, for calculation of heart rate / respiratory rate and determination of sleep information. Use.
The detection threshold value may be, for example, a numerical range (for example, 10 to 100 when the maximum value is 100) equal to or less than the maximum value of the voltage value (or current value) corresponding to the pressure value received from the biosensor 22. it can.
By doing so, minute noise caused by an event other than the target action of the care recipient (for example, vibration caused by a train or a person passing nearby) is eliminated, and the accuracy of determining the sleep state is improved. Can be done.
In addition, the control unit 16 can perform an operation of processing information on biological information according to information on the inclination of the floor plate 82 as a processing means.
Specifically, the operation of adjusting the detection sensitivity of the biosensor 22 can be performed according to the inclination of the bed movable portion (floor plate 82).
This is because the pressure applied to the biosensor 22 (airbag 221) changes according to the inclination of the bed 8 (the larger the inclination, the smaller the pressure). Therefore, when the inclination is large, the detection sensitivity is adjusted to be high. To do.
The operation of adjusting the detection sensitivity of biological information will be described in detail later in "Sensor sensitivity adjustment operation".

Next, the tilt determination / notification operation, the care timing determination / notification operation, and the brightness determination / notification operation included in the information processing method of the present invention will be described with reference to FIGS. 15, 16, and 17. ..
Hereinafter, the information processing method of the present invention will be described in the order of tilt determination / notification operation, care timing determination / notification operation, and brightness determination / notification operation, but the order is not limited to this.

[Tilt judgment / notification operation]
As shown in FIG. 15, in the tilt determination / notification operation, when the tilt of the bed 8 is detected (S11), the time at the time of the detection is acquired (S12), and the tilt determination is performed (S13).
For example, in the monitor device 1, the control unit 16 obtains the inclination angle θ of the floor plate 82 of the bed 8 based on the information detected by the inclination sensor 21, and determines the inclination in relation to the time measured by the time measuring unit 14. ..

The inclination determination is performed, for example, when an angle equal to or greater than a predetermined value is detected for the inclination angle θ of the floor plate 82 of the bed 8 based on the inclination determination condition table t2 shown in FIG. 5, and the detection time is included in the predetermined time zone. In addition, it is determined that the inclination determination condition is satisfied, and otherwise, it is determined that the inclination determination condition is not satisfied (S14).
When the inclination determination condition is satisfied (S14-is satisfied), the information regarding the inclination is set in the SSID (S15).
For example, the identification information "1" indicating an inclination abnormality is set in the 21st digit of the SSID.
As a result, the monitor device 1 transmits the beacon including the SSID in which the information regarding the tilt is set to a predetermined range.

The terminal device 4 that has received the beacon displays information on the tilt based on the SSID included in the beacon (S16).
For example, based on the tilt warning message table t8 shown in FIG. 12 (i), a message such as "the floor plate of the bed is tilted" is displayed on the display unit 43 (see FIG. 13 (ii)).
If the tilt determination condition is not satisfied in the tilt determination (S14-failure), the processes S15 to S16 are not performed.
According to such an inclination determination / notification operation, for example, the floor plate 82 of the bed 8 is inclined during the night time when the care recipient should be sleeping, which hinders the sleep of the care recipient. It is possible to notify (alarm) that it is in an abnormal state as described above.

[Nursing care timing judgment / notification operation]
As shown in FIG. 16, in the care timing determination / notification operation, when biometric information is detected (S21), the sleep state is determined (S22).
For example, in the monitor device 1, the control unit 16 determines whether the care recipient is sleeping or awake based on the biological information detected from the biological sensor 22.
When it is determined to be awake (S22-during awakening), it returns to S21, and when it is determined to be asleep (S22-during sleep), the sleep depth is specified (S23).

Next, the transition timing of the sleep depth is specified (S24).
Specifically, based on the analysis of the past sleep state transition information of the long-term care person (see FIG. 7), if the care recipient is currently in deep sleep, the time until the care recipient shifts to light sleep is calculated, and the care recipient If the person is currently in a light sleep, ask for the time to transition to a deep sleep.
Subsequently, the information regarding the transition timing of the sleep depth is set in the SSID (S25).
For example, the identification information indicating that the sleep will soon shift to deep sleep is set in the SSID, and the identification information indicating that the sleep will soon shift to light sleep is set in the SSID.
As a result, a beacon containing the SSID in which information regarding the transition timing of the sleep depth is set is transmitted to the surroundings.

The terminal device 4 that has received the beacon displays information on sleep depth and information on care timing based on the SSID included in the beacon (S26).
For example, based on the SSID setting information, a message indicating that an early sleep may be recommended soon, or a message indicating that early care is recommended, or a light sleep soon may be displayed. Display a message indicating that you are ready.

[Brightness judgment / notification operation]
As shown in FIG. 17, in the brightness determination / notification operation, when information on brightness is detected (S31), the time is acquired (S32), and brightness determination is performed (S33).
For example, in the monitor device 1, the control unit 16 determines the brightness based on the relationship between the illuminance detected by the illuminance sensor and the time measured by the time measuring unit 14.
The brightness determination is based on the brightness determination condition table t3 shown in FIG. 6, and the brightness determination condition is satisfied, for example, when an illuminance of a predetermined value or more is detected for each care recipient in a predetermined time zone. In other cases, it is determined that the brightness determination condition is not satisfied (S34).
When the brightness determination condition is satisfied (S34-is satisfied), the information regarding the brightness is set in the SSID (S35). For example, the SSID is set with identification information indicating an abnormality (forgot to erase).
As a result, a beacon containing an SSID in which information regarding brightness is set is transmitted to the surroundings.

The terminal device 4 that has received the beacon displays information on brightness based on the SSID included in the beacon (S36).
For example, based on the SSID setting information, a message indicating that the lighting has been forgotten to be turned off is displayed.
If the brightness determination condition is not satisfied in the brightness determination (S34-failure), the processes of S35 to S36 are not performed.

[Sensor sensitivity adjustment operation]
Next, the sensor sensitivity adjusting operation regarding the detection sensitivity of biological information will be described with reference to FIG.
As shown in FIG. 18, in the sensor sensitivity adjustment operation, a detection threshold value corresponding to the detection sensitivity is set in advance (S41).
Specifically, a plurality of different association information that combines the inclination of the bed 8 and the detection threshold value is set, and this is stored in the storage unit 15.
The detection threshold value is set to a numerical range of 100 or less, for example, when the maximum value of the voltage value (or current value) corresponding to the pressure value received from the biosensor 22 is set to 100. For example, the inclination is 0 ° to 5 °, the detection threshold is 10 to 100, the inclination is 5 ° to 10 °, the detection threshold is 5 to 100, the inclination is 10 ° to 15 °, the detection threshold is 0 to 100, and so on. The larger the value, the wider the detection threshold value is associated with.

Then, when the monitor device 1 detects the inclination of the bed 8 and the biological information (S42), the monitor device 1 extracts the biological information included in the detection threshold value according to the inclination of the bed 8 (S43). Specifically, the association information corresponding to the inclination of the bed 8 is specified from the association information stored in the storage unit 15, and the biological information is based on the detection threshold set in the identified association information. Is extracted (S43).
For example, when the inclination of the bed 8 is 7 °, the control unit 16 extracts information included in 5 to 100 from the biological information.
The control unit 16 uses the extracted information as biological information to obtain a heart rate and a respiratory rate, and to determine a sleep state.
In this way, when the bed 8 is tilted, the pressure applied to the airbag 221 due to the load of the care recipient becomes smaller than when the bed 8 is not tilted, thereby preventing the detection sensitivity from being lowered. Can be done. Further, as the inclination of the bed 8 becomes larger, the pressure applied to the airbag 221 becomes smaller, which can prevent the detection sensitivity from being lowered.
That is, the detection sensitivity of the biological information that changes according to the inclination of the bed 8 can be optimally adjusted.

As described above, according to the information processing device, the information processing method, and the information processing program of the present embodiment, it is possible to grasp the sleep posture and the abnormality of the sleep posture of the care recipient from a remote place.
That is, even if the care worker cannot see the state of the bed or is in a place where it is difficult to see the state of the bed, the state of the bed 8 can be grasped through the terminal device 4 in the beacon receivable area. ..
In addition, care can be provided at an appropriate timing and efficiently without imposing a burden on the sleep state of the care recipient as much as possible.
In addition, it is possible to prevent forgetting to turn off the lights and provide a sleeping environment suitable for the care recipient.
In addition, the detection sensitivity of biological information can be appropriately adjusted according to the inclination of the bed 8.

On the other hand, in the conventional information processing device, the care recipient who uses the electric bed 8 unknowingly touches the operation switch at night, so that the floor plate of the bed is unintentionally tilted and the care recipient is self-help. There was a problem that the floorboard could not be returned to its original state, and in this case, the care worker could not immediately grasp this and take appropriate measures.

According to the information processing apparatus, the information processing method, and the information processing program of the present embodiment, it is possible to solve all or a part of such problems that the conventional information processing apparatus should improve.

[Other Embodiments]
Next, as another embodiment of the present invention, embodiments relating to bed tilt, care timing, and brightness determination will be described.

[Other embodiments relating to bed tilt]
For example, in the monitor device 1, in the notification operation in the tilt determination, the time until the notification is performed can be changed depending on whether the tilt is large or small.
Specifically, even when the inclination determination condition is satisfied, if the inclination is less than a predetermined angle, identification information indicating an inclination abnormality is set when the inclination is continuously detected for a predetermined time or longer. By doing so, the notification should not be sent immediately, and if the tilt is more than a predetermined angle, the identification information indicating the tilt abnormality should be set immediately so that the notification is given immediately. Can be done.
In this way, the floor plate 82 of the bed 8 is greatly tilted for some reason, which is suitable when the care recipient is forced to sleep in an unnatural posture, which is highly probable to be abnormal and requires an emergency. On the other hand, when the inclination is small, the probability of being abnormal is low, so it is possible to eliminate waste by immediately responding.

It is also possible to distinguish between a case where the inclination changes slowly and a case where the inclination changes suddenly.
For example, the angle change (angular velocity) per unit time (for example, 1 second) of the tilt angle θ of the floor plate 82 of the bed 8 obtained by the tilt sensor 21 is obtained, and if it is less than a predetermined value, the tilt change is slow. Judgment is made, and if it is more than a predetermined value, it is judged that the change of the inclination is sudden.
Then, in the case where the change in inclination is abrupt and the case where the change in inclination is slow, for example, the same operation as the above-mentioned operation when the inclination is large and when the inclination is small is performed.
In this way, the floor plate 82 suddenly tilts for some reason, which causes the care recipient to sleep in an unnatural posture, which is likely to be abnormal and responds appropriately in an emergency. On the other hand, when the inclination of the floor plate 82 changes slowly, the probability of being abnormal is low, so that waste due to immediate response can be eliminated.

It is also possible to analyze the correlation between bed tilt and sleep depth so that the effect of tilt magnitude on sleep can be grasped.
For example, the sleep state transition information shown in FIG. 7 (i) is recorded in association with the inclination angle θ of the floor plate of the bed, and the analysis information shown in FIG. 7 (ii) is sorted by a certain inclination angle to create data. According to such data, for example, it is possible to specify the inclination of the bed where the deep sleep time increases, and to specify the sleep rhythm (REM sleep, non-REM sleep interval, time zone, etc.) in that case.
Therefore, it can be used as a reference for better sleep of the care recipient in relation to the inclination of the bed, and can be useful for care during sleep.

[Other embodiments relating to care timing]
By a predetermined operation, it is possible to notify a specific care recipient that care should be prioritized.
For example, in the terminal device 4, when a predetermined operation of selecting a specific care recipient who wants to prioritize care is performed, an additional message stored in advance is associated with the care timing message table t10 stored in the storage unit 42. ..
Specifically, in response to the message "I'm about to sleep lightly. Please prepare for long-term care." In the long-term care timing message table t10, for example, "Please give priority to long-term care." Associate the message.
In this way, when the identification information "1" is set in the 25th digit of the SSID included in the beacon in the terminal device 4, the message "It is about to sleep lightly" associated with the care timing message table t10. Please prepare for long-term care. Give priority to long-term care. "Can be displayed.
As a result, for example, when there is a care recipient who could not be cared for during the long-term care time, by selecting the care recipient by the above operation, the care worker is selected at the next care timing. Can be encouraged to give priority to long-term care.
In addition, from past sleep rhythm data, it is possible to generate information that can grasp the effect of nursing care work during sleep on sleep.
For example, it is recorded at which timing during sleep (for example, the time zone, the timing of the light sleep, etc.), and in that case, statistics are obtained regarding the total time of deep sleep, the wake-up time, and the like.
In this way, it is possible to grasp at what timing care can be given to the care recipient to give a good sleep state, and it is possible to provide reference data for better care.

[Other embodiments relating to brightness determination]
Under the brightness determination condition, the sunshine time zone can be automatically calculated based on the position information of the main body of the monitor device 1, and the set time (time zone) can be automatically set based on the sunshine time zone.
For example, the monitor device 1 is provided with a GPS function, the sunshine duration is obtained based on its own latitude and calendar information, the sunshine duration is automatically calculated based on the sunshine duration, and the brightness is calculated. It can be set as the setting time of the judgment condition.
Similarly, it is also possible to acquire the sunset time from an external server or the like via the Internet and automatically set the brightness determination condition as the setting time based on the sunset time.
Further, even when the brightness determination is established, it is possible not to notify when the care recipient is not sleeping or when body movement is detected.
Further, even when the brightness determination is established, the notification may not be performed immediately, but the notification may be performed when the state continues for a predetermined time.

The information processing apparatus, information processing method, and information processing program of the present invention have been described above by showing preferred embodiments, but the information processing apparatus, information processing method, and information processing program according to the present invention have been described above. It goes without saying that the present invention is not limited to the form, and various modifications can be made within the scope of the present invention.
For example, the information about the long-term care person may be displayed as an icon, a message may be displayed, or may be notified by voice.
Further, information can be transferred from the monitor device 1 to the terminal device 4 via a data link in a wired LAN or a wireless LAN connection without using a beacon.
