An information detection device 2 is provided, and a bedding on which a care recipient goes to bed is laid.
In addition, as shown in FIG. 3 (iii), the bed 8 has a driving unit (not shown) that is operated by operating the upper button and the lower button of the operation switch. Is inclined so that the care recipient lying on the bed 8 can be raised or lowered. That is, the bed 8 has a floor plate 82 as a bed movable portion that can change the inclination with respect to the bed frame 81.
The information detection apparatus 2 includes a tilt sensor 21, a biological sensor 22, and a load sensor 23 in a resin casing.
The information detection device 2 includes a control unit, a communication unit, and the like, and transmits detection information detected by each sensor to the monitor device 1.

As shown in FIG. 2, the monitor device 1 includes an external sensor information receiving unit 11, an internal sensor 12, a wireless communication unit 13, a time measuring unit 14, a storage unit 15, and a control unit 16. .

The external sensor information receiving unit 11 corresponds to the receiving means of the present invention. As shown in FIGS. 1 and 2, the external sensor information receiving unit 11 is connected to the information detection device 2 via a communication cable or the like, and the information detected by the sensor is transferred from the information detection device 2 to the communication cable or the like. Receive via.

The tilt sensor 21 is composed of, for example, a gyroscope or an acceleration sensor.
The inclination sensor 21 detects a component of gravitational acceleration (gravitational acceleration vector value g ′) in a direction orthogonal to the surface of the floor plate 82 (see FIGS. 1 and 3 (iii)), and uses this as information on the inclination of the bed movable part. Is transmitted to the monitor device 1 as follows.
Thereby, in the monitor apparatus 1, the external sensor information receiving part 11 receives the information regarding the said inclination (gravity acceleration vector value g ').
In the monitor device 1, the floor board is based on the relationship (g ′ = g cos θ) between the gravitational acceleration g acquired in a state where the floor board 82 is not tilted in advance and the gravitational acceleration vector value g ′ actually detected by the tilt sensor 21. 82 can be obtained (see FIG. 3 (iii)).
With this inclination angle θ, it is possible to specify the posture of the cared person in the bed 8 (upper body posture).
In addition, the inclination sensor 21 can also be attached to another movable part. For example, when the part of the floor board 82 corresponding to the lower leg part is a movable part that can be tilted, the inclination sensor 21 is attached to the floor board part that is the movable part, thereby specifying how much the floor board part is tilted. be able to.

The biological sensor 22 detects an airbag 221 whose internal pressure fluctuates due to an external action, and a relatively small pressure in the airbag 221 and generates an electrical signal corresponding to this pressure as biological information. It consists of.
For example, the airbag 221 is disposed on the floor plate 82 at a position corresponding to the chest of the care receiver lying on the bed 8, and the pressure detection unit 222 is provided in the casing of the information detection device 2. Velcro tape (registered trademark) is provided on the back surface of the airbag 221 and the 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). Yes.
According to this biological sensor 22, it is possible to detect minute vibrations (micromotion) associated with the heartbeat / respiration of the care recipient lying on the bed 8, and an electric signal indicating a pressure value corresponding to the micromotion is generated. It can transmit to the monitor apparatus 1 as biometric information.
Thereby, the monitor apparatus 1 receives the biological information of the cared person lying on the bed 8 and acquires the heart rate and the respiratory rate of the cared person based on the biological information, or based on the heart rate and the respiratory rate. Thus, it becomes possible to specify the sleeping state of the care recipient.

The load sensor 23 uses an airbag 221 used for the biological sensor 22, detects a relatively large pressure (load) in the airbag 221, and generates an electrical signal corresponding to the load.
According to the load sensor 23, relatively large vibration (coarse body motion) associated with entering or leaving the floor can be detected, and an electric signal indicating a load value corresponding to the coarse body motion is transmitted to the monitor device 1. Can do.
Thereby, on the monitor device 1 side, it is possible to determine whether the cared person enters or leaves the floor based on a change in the presence or absence of the load value from the load sensor 23, and a load value of a certain level or more is continuously received. Thus, the presence of the care recipient can be determined.
Further, in the case where the user is in the bed, the load value varies depending on the distance between the load sensor 23 and the cared person, so that the position of the cared person 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.
The internal sensor 12 can detect environmental information such as the temperature, humidity, illuminance, and the like around the bed 8.
Each sensor constituting the internal sensor 12 can be provided outside the main body of the monitor device 1 and information detected from each sensor can be received via the external sensor information receiving unit 11.

The wireless communication unit 13 has a function corresponding to the output unit of the present invention. Specifically, the monitor device 1 includes an antenna (not shown) that transmits a predetermined radio wave, and the wireless communication unit 13 is located within a predetermined range (receivable area) where the radio wave can be received. 4 outputs information via wireless communication.
More specifically, the wireless communication unit 13 is a wireless LAN (Wi-Fi: registered trademark) communication interface corresponding to the IEEE802.11 standard (referring to general wireless LAN standards including IEEE802.11b / g). 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. In this state, the terminal device 4 located in the receivable area transmits a beacon. It can be received. 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 request.
Thereby, 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 according to the present embodiment does not use the data link established by such Wi-Fi connection, but uses the beacon transmitted to the surroundings prior to the Wi-Fi connection. Various information is exchanged.

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 terminal device 4 that has received the beacon changes the SSID included in the beacon. Various information is displayed based on this.
For example, the beacon is transmitted at an interval of 100 milliseconds as a receivable area in a concentric range with a line-of-sight of about 100 m centering on the monitor device 1.
For this reason, the terminal device 4 can receive the information output from the monitor device 1 immediately.
Moreover, the terminal device 4 can pass information only by being located within 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 timer unit 14 measures time information such as date, time, and elapsed time.
The timekeeping unit 14 includes, for example, a time when the care receiver leaves the bed, a time when the user enters the bed, a time when the user is asleep, a time when the person is awakened, a time when the sleeper transitions from deep sleep to deep sleep, a time when the sleep shifts from deep sleep to shallow sleep, It is possible to measure the time from sleep to sleep, the time zone of shallow sleep, the time zone of deep sleep, and the like.

The storage unit 15 is configured by, for example, a nonvolatile memory such as a ROM, a RAM, an EEPROM, a flash memory, or the like, and is a storage unit that stores programs and data for executing the functions of the monitor device 1.
The program stored in the storage unit 15 includes software capable of executing an inclination determination / informing operation, a care timing determination / informing operation, and a brightness determination / informing operation according to the information processing method of the present invention.
The data stored in the storage unit 15 includes a care receiver registration table shown in FIG. 4, an inclination determination condition table shown in FIG. 5, a brightness determination condition table shown in FIG. 6, and a sleep state transition shown in FIG. 7 (i). Information, analysis information shown in FIG. 7 (ii), and the like.

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

As shown in FIG. 9 (i), the SSID is identification information consisting of alphanumeric characters and symbols of up to 32 digits constituting 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, change information that varies depending on the state and environment of the care recipient is set.
In addition, in the first to eleventh digits, the monitor device management number and the name of the care receiver are set with reference to the care receiver registration table t1 (see FIG. 4) stored in the storage unit 15.

  As shown in FIG. 9 (ii), the fluctuation information is, for example, identification information that can identify the bed and sleep states, environment information, information about tilt, information about brightness, sleep depth, and timing of transition to deep sleep. There is identification information that can specify the timing of transition to shallow sleep, identification information that can specify the presence or absence of body movement, and biological information, which can be set at a predetermined timing (for example, every time a beacon is transmitted). it can. A method for setting each variation information will be described below.

With respect to the occupancy state, the control unit 16 determines “entering floor”, “flooring”, and “leaving” based on the load value detected by the load sensor 23.
For example, if a load value greater than or equal to a predetermined value is detected, it is determined as “entering the floor”, and if a load value greater than or equal to the predetermined position is continuously detected, it is determined as “flooring”, When the load value is no longer detected, it is determined as “getting out of bed”.
If it is determined that the user is present, the identification information “1” is set at the 12th digit of the SSID, and if it is determined that the user is out of bed, the identification information “0” is set.

Regarding the sleep state, the control unit 16 determines whether it is “sleeping” or “awake” based on the biological information received from the biological sensor 22.
For example, when a unique heartbeat / respiration indicating sleep is detected in the biological information received from the biological sensor 22, it is determined as “sleeping”, and otherwise, it is determined as “awake”.
When it is determined as “sleeping”, the identification information “0” is set at the 13th digit of the SSID, and when it is determined as “awake”, information setting is not performed.

About temperature, humidity, and illumination intensity, each information detected by the temperature sensor which is the internal sensor 12, a humidity sensor, and an illumination intensity sensor is set.
For example, the control unit 16 sets temperature information at the 14th to 15th digits of the SSID, humidity information at the 16th to 17th digits, and illuminance information at the 18th to 20th digits.

With respect to the information related to the tilt, the control unit 16 operates as a tilt determination unit, and based on the information regarding the tilt of the bed movable unit (floor plate 82) received from the tilt sensor 21 and the information regarding the presettable period, It is determined whether an inclination determination condition is satisfied.
“Information relating to the tilt of the bed movable portion” is the tilt 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 tilt sensor 21.
“Information relating to a pre-settable period” is, for example, a night time zone in which the cared person seems to be sleeping, and can be set in advance by a predetermined operation.
The “tilt determination condition” is a condition shown in the tilt determination condition table t2 shown in FIG. 5, and the control unit 16 operates in the time zone (21: 0 to 6:00) set in the “set time” field. When the inclination angle θ of the floor plate 82 that is 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, for example, the floor plate 82 of the bed 8 is slanted for some reason and the care recipient cannot return to the original state.
When it is determined by the determination by the inclination determination means that the inclination determination condition is satisfied, the control unit 16 sets identification information “1” at the 21st digit of the SSID as information regarding the inclination. As a result, the wireless communication unit 13 transmits the beacon including the SSID in which the information about the tilt is set.
That is, the wireless communication unit 13 is configured to output information related to the tilt when it is determined by the tilt determination means that the tilt determination has been established.
Thereby, in the terminal device 4 side, the care receiver in the state where the inclination of the bed 8 is abnormal can be specified.
In consideration of the fact that sleeping hours and sleeping postures are different for each care recipient, in the inclination determination condition table t2, “setting time” and “bed inclination” are changed for each care recipient. You can also
In addition, as information regarding the inclination, the inclination angle θ of the floor board 82 can be set to SSID. If it does in this way, the state of each care recipient's bed 8 can always be grasped.

Regarding the information related to the brightness, the control unit 16 operates as a brightness determination unit, so that whether or not the brightness determination condition is satisfied based on the information regarding the brightness around the bed and the information regarding a presettable period. Determine whether.
The “information about the brightness around the bed” is, for example, the illuminance detected by the illuminance sensor that is the internal sensor 12.
“Information relating to a pre-settable period” is, for example, a night time zone in which the cared person seems to be sleeping, and can be set in advance by a predetermined operation.
The “brightness determination condition” is a condition shown in the brightness determination condition table t3 shown in FIG. 6. For example, regarding the uppermost condition, the control unit 16 sets the cared person set in the “name” column. For Tetsuji Yamada, an illuminance greater than or equal to the illuminance (300 Lx) set in the “set illuminance” column was detected in the time zone (21: 0 to 6:00) set in the “set time” column In this 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 by the determination by the brightness determination unit that the brightness determination condition is satisfied, the control unit 16 sets identification information “1” at the 22nd digit of the SSID as information regarding brightness.
Thereby, in the terminal device 4 side, it is possible to specify a care recipient who has an abnormal room brightness.
Note that the illuminance can also be set to SSID as information about brightness. In this way, it is possible to always grasp the brightness around each cared person.

Regarding the sleep depth, the control unit 16 determines whether the care receiver during sleep is a light sleep or a deep sleep based on the biological information detected by the biological sensor 22.
Specifically, in the biometric information, when information on a specific heartbeat / respiration corresponding to shallow sleep (REM sleep) is detected, it is determined as “shallow sleep”, and a specific heartbeat / response corresponding to deep sleep is determined. If information related to respiration is detected, it is determined as “deep sleep”.
Then, the control unit 16 sets the identification information “0” at the 23rd digit of the SSID when it is determined that it is light sleep, and sets identification information “1” when it is determined that it is “deep sleep”.

The transition timing to deep sleep and the transition timing to shallow sleep can be obtained based on the sleep rhythm analyzed by the transition of the sleep state of the care recipient.
By the way, the timing of shifting to deep sleep and the timing of shifting to shallow sleep are important information for providing care at an appropriate timing.
This is because the cared person may need assistance such as turning over or changing diapers even during sleep. In this case, it is less burdensome for the cared person to perform assistance when the sleep is shallow. This is because it is recommended.
In other words, if the cared person is currently in a light sleep state (careable period), care must be taken before moving to deep sleep, and if the cared person is currently in deep sleep state, Caregiving can be performed efficiently while minimizing the burden on the care recipient as much as possible, such as preparing for nursing care or performing work other than nursing care after knowing the period during which care is possible.

Therefore, for example, as shown in FIG. 7 (i), the control unit 16 sets the time when the user enters the bed → the time when the user falls asleep (the time when the REM sleep state (first time) is shifted) → the non-REM sleep (first time). ) → Time to shift to REM sleep (second time) → Time to shift to non-REM sleep (second time) → Time to shift to REM sleep (third time) → ... → Time to get up → Time to leave The sleep state transition is extracted for each care recipient and stored in the storage unit 15 as sleep state transition information.
And based on this sleep state transition information, a care receiver's sleep rhythm is analyzed.
For example, as shown in FIG. 7 (ii), the time from going into bed to sleep (the first REM sleep) (sleeping time), the time from going into bed to the non-REM sleep (first time), non-REM Find the time of sleep (first time), the time from bed entry 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) The average value is obtained.
According to such analysis information, the transition timing of REM sleep and non-REM sleep that are alternately repeated a plurality of times every predetermined time in one sleep can be specified for each care recipient.

And the control part 16 operate | moves as a subject information control means, and the subject information which linked | related the information regarding the timing which transfers to deep sleep and the other information regarding the carable person of the target which can be preset is the terminal device 4. Can be output.
Specifically, the control unit 16 specifies the current sleep depth of the care recipient based on the biological information, and obtains the time until shifting to deep sleep by calculation when light sleep.
For example, when the current sleep depth of the care recipient is non-REM sleep (first time), an elapsed time Ta from the transition to non-REM sleep (first time) to the present is obtained, and analysis information (FIG. 7 ( The time (average value) Tb of non-REM sleep (first time) is taken out from ii), and the time obtained by subtracting Ta from Tb can be obtained as the time until the transition to deep sleep.
For example, when the time to shift to deep sleep is within 10 minutes, the control unit 16 sets identification information “1” at the 24th digit of the SSID, and sets identification information “0” within 30 minutes. To do.
Thereby, in the terminal device 4 side, the timing which a care available period ends can be specified.
In addition, when the current sleep state is deep sleep, the control unit 16 obtains the time until shifting to shallow sleep in the same manner, and if it is within 10 minutes, the identification information “1” is displayed in the 25th digit of the SSID. Set.
Thereby, in the terminal device 4 side, the timing at which the nursing care possible period is started next can be specified.
In addition, time information and a time slot | zone can also be set to SSID as timing (information regarding care timing) which transfers to a light sleep or deep sleep. As a result, it is possible to accurately grasp the nursing care timing, grasp the nursing care timing that has been performed a plurality of times, and use it for nursing care.

Regarding the body movement, the control unit 16 can determine the presence or absence of the body movement of the cared person based on the load value and the change in the load value from the load sensor 23.
When determining that there is a body movement, the control unit 16 sets identification information “1” at the 26th digit of the SSID.

The biological information corresponds to a heart rate and a 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 at the 27th to 28th digits of the SSID and the respiration rate at the 29th to 30th digits.

By the way, the control part 16 can perform the operation | movement which processes the information regarding biometric information as a process means.
For example, the detection threshold value is stored in the storage unit 15 in advance, and only information included in the detection threshold value is extracted from the biological information acquired from the biological sensor 22 to calculate the heart rate / respiration rate and to determine sleep information. Use.
For example, the detection threshold value may be a numerical range equal to or less than the maximum value of the voltage value (or current value) corresponding to the pressure value received from the biological sensor 22 (for example, 10 to 100 when the maximum value is 100). it can.
In this way, fine noise caused by an event other than the target action of the care recipient (for example, vibration caused by passing a train or a person nearby) is eliminated, and the determination accuracy of the sleep state is improved. Can do.
Moreover, the control part 16 can perform the operation | movement which processes the information regarding biological information according to the information regarding the inclination of the floor board 82 as a process means.
Specifically, an operation of adjusting the detection sensitivity of the biosensor 22 according to the inclination of the bed movable part (floor plate 82) can be performed.
This is because the pressure applied to the biosensor 22 (airbag 221) changes according to the tilt of the bed 8 (the smaller the tilt, the smaller the pressure). Therefore, when the tilt is large, the detection sensitivity is adjusted to be high. To do.
The operation for adjusting the detection sensitivity of biological information will be described in detail later in the “sensor sensitivity adjustment operation”.

Thereby, the care worker can grasp that the inclination of the bed 8 is abnormal for the specific care recipient via the terminal device 4.

Based on the 22nd digit information, information on brightness is displayed.
Specifically, based on the illumination state icon table t6 shown in FIG. 11 (iii), when “1” is set, the icon d indicating that the illumination is on is overlaid on the presence state icon. Display (see FIG. 13 (iii)).
Further, based on the brightness warning message table t11 shown in FIG. 12 (iv), a message “illumination is turned on” indicating that the lighting has been forgotten to be turned off is displayed (see FIG. 13 (iii)).
Thereby, the care worker can grasp that the brightness of the room is abnormal (forgetting to turn off the lighting) for the specific care receiver via the terminal device 4.

Based on the 23rd digit information, information on the sleep depth is displayed.

Further, the heart rate and the like can be displayed by a graph. For example, the heart rate, respiration, and body movement graph of FIG. 13 (iv) indicates the signal level by a square, and the number of squares increases or decreases according to the heart rate, the respiratory rate, and the size of the body movement.
Moreover, a care receiver's state can be shown with a graph. For example, the heart rate graph can indicate normality when the number of squares is maximum.

By the way, as shown in FIG. 14 (i), the terminal device 4 normally displays the information of each care recipient in the order of management numbers (from left to right in the order of 0051, 0052, 0053). The display can be changed in the recommended order.
Specifically, on the display screen shown in FIG. 14 (i), when the operation unit 44 selects and operates the “recommended care order” button at the lower right, the control unit 45 refers to each SSID stored in the RAM. , Information of the care recipient in which the identification information of “0” or “1” is set in the 24th digit is extracted.

Here, as shown in FIG. 9 (ii), the care recipient “Sato” who is set to “0” shifts to deep sleep within 30 minutes, so the remaining time of the careable period is low and priority is given.

Next, the inclination determination / informing operation, the care timing determination / informing operation, and the brightness determination / informing 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 / informing operation, care timing determination / informing operation, brightness determination / informing 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 detection is acquired (S12), and the tilt is determined (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 performs the inclination determination in relation to the time measured by the time measuring unit 14. .

For example, the inclination determination is based on an inclination determination condition table t2 shown in FIG. 5 in which an angle greater than or equal to a predetermined value is detected for the inclination angle θ of the floor plate 82 of the bed 8 and the detection time is included in a predetermined time zone. Then, it is determined that the inclination determination condition is satisfied, and otherwise, it is determined that it is not satisfied (S14).
When the inclination determination condition is satisfied (S14—established), information regarding the inclination is set in the SSID (S15).
For example, identification information “1” indicating tilt abnormality is set at the 21st digit of the SSID.
Thereby, the monitor apparatus 1 transmits the beacon containing the SSID in which the information regarding inclination is set to a predetermined range.

The terminal device 4 that has received the beacon displays information about the inclination 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 of the bed is tilted” is displayed on the display unit 43 (see FIG. 13 (ii)).
In addition, when the inclination determination condition is not satisfied in the inclination determination (S14—not satisfied), the processes of 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 a night time when the care recipient should be sleeping, thereby inhibiting the care receiver's sleep. Notification (alarm) of an abnormal state as described above can be performed.

[Nursing care timing determination / notification operation]
As shown in FIG. 16, in the care timing determination / notification operation, when biological 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 receiver is sleeping or awake based on the biological information detected from the biological sensor 22.
When it is determined that the user is awake (S22-awake), the process returns to S21, and when the sleep is determined (S22-sleeping), the sleep depth is specified (S23).

Next, the transition timing of the sleep depth is specified (S24).
Specifically, based on the analysis of information on the transition of the sleep state of the cared person (see FIG. 7), if the cared person is currently deep sleep, the time required to shift to light sleep is obtained, If the person is currently lightly asleep, seek the time to transition to deep sleep.
Subsequently, information regarding the transition timing of the sleep depth is set in the SSID (S25).
For example, identification information indicating that a transition to deep sleep will soon be set in the SSID, or identification information indicating a transition to shallow sleep will be set in the SSID.
Thereby, the beacon including the SSID in which the information related to 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 the sleep depth and information on the nursing care timing based on the SSID included in the beacon (S26).
For example, based on the SSID setting information, it will soon shift to deep sleep, and for this reason, it will display a message indicating that early care is recommended, or it will soon move to shallow sleep. Displays a message indicating that it is preparing.

[Brightness judgment / informing operation]
As shown in FIG. 17, in the brightness determination / informing operation, when information about 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 performs brightness determination on the relationship between the illuminance detected by the illuminance sensor and the time measured by the timer unit 14.
The brightness determination is based on the brightness determination condition table t3 shown in FIG. 6, for example, when the illuminance of a predetermined value or more is detected for each care recipient in a predetermined time zone. Otherwise, it is determined that the brightness determination condition is not satisfied (S34).
When the brightness determination condition is satisfied (S34—established), information regarding brightness is set in the SSID (S35). For example, identification information indicating abnormality (forgetting to erase) is set in the SSID.
Thereby, a beacon including an SSID in which information about brightness is set is transmitted to the surroundings.

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

[Sensor sensitivity adjustment operation]
Next, the sensor sensitivity adjustment 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 corresponding to the detection sensitivity is set in advance (S41).
Specifically, a plurality of different association information combining the tilt of the bed 8 and the detection threshold is set and stored in the storage unit 15.
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, the detection threshold is set to a numerical value range of 100 or less. For example, the detection threshold is 10 to 100 when the inclination is 0 ° to 5 °, the detection threshold is 5 to 100 when the inclination is 5 ° to 10 °, and the detection threshold is 0 to 100 when the inclination is 10 ° to 15 °. A larger detection threshold is associated with a larger value.

And the monitor apparatus 1 will extract the biological information contained in the detection threshold value according to the inclination of the bed 8, if the inclination and biological information of the bed 8 are detected (S42). Specifically, the association information corresponding to the tilt of the bed 8 is identified from the association information stored in the storage unit 15, and the biometric information is based on the detection threshold set in the identified association information. Is extracted (S43).
For example, the control part 16 extracts the information contained in 5-100 from biometric information, when the inclination of the bed 8 is 7 degrees.
The control unit 16 uses the extracted information as biological information to obtain a heart rate and a respiration rate, and uses it for determination of a sleep state.
In this way, when the bed 8 is tilted, the pressure applied to the airbag 221 by the load of the cared person is smaller than when the bed 8 is not tilted, thereby preventing the detection sensitivity from being lowered. Can do. Further, the greater the inclination of the bed 8, the smaller the pressure applied to the airbag 221, thereby preventing the detection sensitivity from being lowered.
That is, it is possible to optimally adjust the detection sensitivity of biological information that changes according to the inclination of the bed 8.

As described above, according to the information processing apparatus, the information processing method, and the information processing program of this embodiment, it is possible to grasp the care receiver's sleep posture and sleep posture abnormality from a remote location.
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 8 can be grasped via the terminal device 4 in the beacon receiving area. .
Moreover, care can be performed efficiently at an appropriate timing without imposing a burden on the sleep state of the care recipient as much as possible.
Moreover, it is possible to prevent forgetting to turn off the lighting and provide a sleep environment suitable for the care recipient.
Further, the detection sensitivity of biological information can be appropriately adjusted according to the inclination of the bed 8.

  On the other hand, in a conventional information processing apparatus, a cared person using the electric bed 8 unintentionally touches the operation switch at night, and thereby the floor of the bed inclines unintentionally, and the cared person is free to use by himself. There was a problem that the floorboard could not be returned to the original state, and in this case, the care worker could not immediately grasp this and take appropriate action.

  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 part of such problems that the conventional information processing apparatus should improve.

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

[Other Embodiments Regarding Bed Tilt]
For example, in the monitoring device 1, in the notification operation in the tilt determination, it is possible to change the time until the notification is performed 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 inclination abnormality is set when the inclination is continuously detected for a predetermined time or more. To prevent immediate notification, and when the inclination is larger than a predetermined angle, immediately set the identification information indicating an abnormality of the inclination to immediately notify Can do.
In this way, the floor plate 82 of the bed 8 is greatly inclined for some reason, and this is appropriate when the cared person is forced to sleep in an unnatural posture and has a high probability of being abnormal and requires urgent action. On the other hand, when the inclination is small, the probability of being abnormal is low, so that waste due to immediate response can be eliminated.

It is also possible to detect the case where the change in inclination is slow and steep.
For example, an angle change (angular velocity) per unit time (for example, 1 second) of the inclination angle θ of the floor plate 82 of the bed 8 obtained by the inclination sensor 21 is obtained. If the inclination change is less than a predetermined value, the inclination change is slow. If it is greater than or equal to a predetermined value, it is determined that the change in the slope is abrupt.
Then, an operation similar to the operation when the inclination is large or small is performed, for example, when the change in inclination is steep and when the change in inclination is slow.
In this way, the floor board 82 suddenly tilts for some reason, and accordingly, the caregiver is forced to sleep in an unnatural posture, so that it is appropriate to cope with a high probability of abnormality and an urgent need. On the other hand, when the change in the inclination of the floor plate 82 is slow, the probability of being abnormal is low, so that waste due to immediate response can be eliminated.

Further, the correlation between the bed inclination and the sleep depth can be analyzed so that the influence of the inclination 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 of the bed, and data in which the analysis information shown in FIG. 7 (ii) is sorted for each fixed inclination angle is created. According to such data, for example, it is possible to specify the inclination of the bed where the time of deep sleep increases, and to specify the sleep rhythm (rem sleep, non-REM sleep interval, time zone, etc.) in that case.
For this reason, it can serve as a reference for better sleep of the care recipient in relation to the tilt of the bed, and can also be used for care during sleep.

[Other Embodiments Regarding Care Timing]
By a predetermined operation, it is possible to notify a specific care receiver that priority should be given to care.
For example, in the terminal device 4, when a predetermined operation for selecting a specific care recipient who wants to give priority to care is performed, the additional message stored in advance is associated with the care timing message table t <b> 10 stored in the storage unit 42. .
Specifically, in response to a message such as “You are about to fall asleep soon. Please prepare for care.” In the care timing message table t10, for example, “Please give priority to care.” Associate messages.
In this way, in the terminal device 4, when the identification information “1” is set in the 25th digit of the SSID included in the beacon, the message “Nearly shallow sleep” associated with the care timing message table t <b> 10. “Please prepare for care. Please give priority to care.” Can be displayed.
Thereby, for example, when there is a cared person who could not be cared for during the nursing time, the cared person selected at the next care time is selected for the care worker by selecting the cared person by the above operation. Can be encouraged to give priority to care.
Moreover, the information which can grasp | ascertain the influence which the nursing work implementation during sleep has on sleep can also be produced | generated from the past sleep rhythm data.
For example, it is recorded at which timing during sleep (for example, time zone, the number of times of shallow sleep, etc.), and in that case, statistics are obtained for the total time of deep sleep, the wake-up time, and the like.
If it does in this way, it can grasp | ascertain when it can give a caregiver a good sleep state when performing care, and can provide the data used as a reference in order to perform better care.

[Other Embodiments Regarding 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, obtains a sunshine time zone based on its own latitude and calendar information, and automatically calculates a time zone during sleep at night based on this sunshine time zone. It can be set as the setting time of the determination condition.
Similarly, the sunset time can be acquired from an external server or the like via the Internet, and automatically set as the setting time of the brightness determination condition based on the sunset time.
Further, even when the brightness determination is established, it is possible to prevent notification when the cared person is not sleeping or when body movement is detected.
Further, even when the brightness determination is established, notification is not performed immediately, and notification can 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 with reference to the preferred embodiments, but the information processing apparatus, information processing method, and information processing program according to the present invention are described above. Needless to say, the present invention is not limited to the embodiments, and various modifications can be made within the scope of the present invention.
For example, the information regarding the cared person may be an icon display or a message display, or may be configured to be notified by voice.
Information can be transferred from the monitoring device 1 to the terminal device 4 via a data link in a wired LAN or wireless LAN connection without using a beacon.
