  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. The contents of the present invention are not limited to the contents of the following embodiments.

[1. First Embodiment]
Control of the light intensity in the lighting device is performed in accordance with the sleep state of the user. However, it was merely performed to darken when sleeping and to brighten when awake.

  Many prior arts that adjust the light intensity to make a transition to a better sleep state have been proposed, but in order to maintain a wakeful state without burden on the user or to achieve an appropriate sleep rhythm, a lighting device It has not been done to control the brightness.

  So, according to the 1st assistance system of this embodiment, it is possible to support maintaining or improving a user's sleep state appropriately by controlling the brightness of an illuminating device. A support system can be provided.

  In this specification, a user means a person who uses a bed apparatus (mattress), and is not limited to a person who receives treatment due to illness, as long as it is a person who receives care at a facility or sleeps on a bed apparatus. Even a healthy person can be applied as a user.

  Further, in this specification, an administrator is a person who sets and controls various devices, and refers to a medical worker, a staff such as a facility, and a home caregiver. Note that the user himself / herself may be an administrator and perform various settings.

  The user and the administrator are collectively referred to as a target person of the support system 1. Therefore, the term “subject” may be either a user or an administrator.

[1.1 Overall system]
FIG. 1 is an overall view of a support system 1 in the present embodiment. As shown in FIG. 1, in the support system 1, a plurality of lighting devices are arranged as the lighting system 20 around the bed device 5 and its periphery. The lighting system 20 includes a brightest first lighting device 22, a second lighting device 24 provided on the headboard, and a third lighting device 26 provided at the foot of the bed device 5 (frame of the bed device 5). Have.

  Here, the first illumination device 22 can irradiate the brightest, followed by the second illumination device 24. The third lighting device 26 is the darkest. One or more devices may be provided. In FIG. 1, a plurality of third illumination devices 26 are provided at the frame end of the bed device 5.

  The control device 10 is a device for controlling the entire support system 1. In this embodiment, each device is controlled from another device as a tablet-type device. In addition, the control apparatus 10 may be incorporated in the lighting system 20 (for example, the 1st lighting apparatus 22), and may be provided when an application is installed in a user's terminal device (for example, smart phone). .

  A sensor device 14 is placed on the bed device 5. The sensor device 14 is a sensor that detects the body movement of the user in the bed device 5. By using the sensor device 14, the control device 10 can acquire biological information values such as the user's heart rate and respiratory rate, or can detect the user's posture and the like.

  For example, the sensor device 14 may be placed on a mattress on the bed device 5 or may be placed between the bed device 5 (bottom portion) and the mattress. The sensor device 14 may be placed on the bed device 5 (on the bottom portion or the mattress) at a position where the user's body movement can be detected. The position where the sensor device 14 is placed is preferably a place where the back of the user is located.

  For example, as shown in FIG. 1B, the sensor device 14 is placed under the mattress 7. At this time, the sensor device 14 is placed at a position M2 from the head side end so as to be located on the back (near the chest) of the patient P. For example, M2 is a distance of 40 cm.

  Further, the sensor device 14 may be realized by providing a load sensor under the bed device 5 (between the floor and the bed device 5), or by detecting a user's body movement by providing a strain gauge on the frame. May be.

  The stand device 30 is a stand on which various units can be installed. The stand device 30 is movable along the longitudinal direction M1 of the bed device 5. The stand device 30 can provide various functions to the user by combining various units. The configuration of the stand device 30 will be described in detail in another embodiment.

  In addition, when the stand unit 30 is provided with a lighting unit, it may function as a lighting device of the lighting system 20. For example, instead of the first lighting device 22, a lighting unit provided in the stand device 30 may be used.

  The control device 10, the illumination system 20, the stand device 30, and the sensor device 14 are generally connected by wireless communication. As wireless communication, they may be connected by the same wireless network (for example, WLAN), or may be connected by short-range wireless communication (for example, Bluetooth (registered trademark)). Some devices may be connected by wire.

  Further, as will be described later, the control device 10 may be further connected to another device. For example, the control device 10 is connected to a bed control device (not shown) that controls the bed device 5 to acquire the state of the bed device 5 or control the bed device 5 (for example, raising / lowering the back). Control).

  In the present embodiment, an example in which the control system 10 controls the support system 1 will be described, but the stand device 30 may be provided with a control function. Further, the control device 10 may be controlled via the stand device 30.

[1.2 Functional configuration]
Next, in the support system 1 according to the present embodiment, a functional configuration centered on the control device 10 will be described with reference to FIG.

  The control device 10 includes a control unit 100, a storage unit 120, a display unit 130, an operation unit 135, a notification unit 140, a voice input / output unit 145, and a communication unit 150. The communication unit 150 can be connected to the bed control device 12, the sensor device 14, the environment information acquisition device 16, and the lighting system 20.

  The control unit 100 controls the entire control device 10. The control unit 100 is one or more arithmetic devices (for example, a CPU (Central Processing Unit)) that implements various functions by reading and executing various programs stored in the storage unit 120.

  The control unit 100 reads out and executes the program stored in the storage unit 120 to thereby execute the scheduled activity time setting unit 102, the bed control unit 104, the sleep state determination unit 106, the bed leaving determination unit 108, and the biological information value acquisition unit. 110, functions as the environment information acquisition unit 112 or the illumination control unit 114.

  The scheduled activity time setting unit 102 sets the scheduled activity time of the user. The scheduled activity time is the time when the user should be awake. The scheduled activity time is included and stored in user information in a user information storage area 122 described later. The scheduled activity time setting process realized by the scheduled activity time setting unit 102 will be described later with reference to the drawings.

  The bed control unit 104 controls the bed control device 12 to realize a back-up operation and a back-down operation. Usually, the bed apparatus 5 shown in FIG. 1 has a back bottom, a waist bottom, a knee bottom (upper leg section), and a foot bottom (lower leg section), and the back bottom is rotated. Realizes back-up / back-down operation. Further, by rotating the knee bottom and the foot bottom, a knee raising / knee lowering (foot raising / foot lowering) operation is realized.

  In the present embodiment, the bed control unit 104 will be described centering on operating the back bottom, but the knee bottom and the foot bottom may be controlled, and the back bottom, the knee bottom, and the foot bottom are interlocked. May be.

  For example, when the bed control unit 104 gives an instruction to set the back raising angle (the angle at which the back bottom is raised from the horizontal state such as the floor surface or the bed frame surface, the back angle) to “30 degrees”, the bottoms individually or in combination The back angle becomes “30 degrees”.

  The bed control unit 104 also controls the height (high / low) of the bed device 5 and air cell control when the air cell control device is connected (for example, control for changing the internal pressure of each cell in the main cell). It is also possible to perform a rollover control using a side air cell).

  The bed control unit 104 can also acquire the state of the bed apparatus 5. For example, various states such as the back angle of the bed device 5 (the angle at which the back bottom is raised from the horizontal state), the height of the bed device, and the state of the air cell can be acquired.

  The sleep state determination unit 106, the bed leaving determination unit 108, and the biological information value acquisition unit 110 use the sensor device 14 to acquire various states of the user.

  The sensor device 14 is, for example, a pressure sensor, and detects a user's biological signal based on a change in pressure. When obtaining (calculating) a biological information value from a biological signal, extract a respiratory component / heart rate component from the received biological signal (body motion), and calculate a respiratory rate and a heart rate based on the respiratory interval and the heart rate interval. To do. Alternatively, the periodicity of body motion may be analyzed (Fourier transform or the like), and the respiration rate and heart rate may be calculated from the peak frequency.

  The acquired biological information value is stored in the user information storage area 122 as user information. Here, the biometric information value is stored as user information every predetermined time. For example, biometric information values (for example, heart rate, respiration rate, activity amount) are stored every time.

  The biometric information value acquisition unit 110 stores a biometric information value every predetermined time. For example, it may be every predetermined time such as every 5 seconds, every 30 seconds, every 1 minute, every 2 minutes, or every 10 minutes. The range stored as the user information may be stored within a predetermined range such as 24 hours, the user being in bed, or overnight. In addition, biometric information values for a predetermined period of two days, three days, and one week may be stored.

  The sleep state determination unit 106 determines the sleep state of the user. As the sleep state, “sleep” and “wakefulness” are determined when the user is in bed. The determined “sleep” may further determine a stage such as “REM / non-REM sleep”.

  As a method for determining the sleep state of these users, for example, JP 2010-264193 A (invention name: sleep state determination device, program and sleep state determination system, filing date: May 18, 2009) The sleep state determination method described in Japanese Patent Application No. 2014-229118 (Title of Invention: Sleep State Determination Device, Sleep State Determination Method and Program, Application Date: November 11, 2014) can be used. This patent application is incorporated by reference in its entirety.

  The sleep state determined by the sleep state determination unit 106 is stored in the sleep state storage area 124 of the storage unit 230. The sleep state is preferably stored every predetermined time for each user.

  In addition, the bed leaving determination unit 108 determines whether the user is getting out of bed / bed. The determination of getting out of bed / being present may be made based on a biological signal received from the sensor device 14, or may be made by using a bed / out of bed sensor provided separately. The bed / bed state may be stored together with the sleep state storage area 124.

  The environment information acquisition unit 112 acquires environment information from the environment information acquisition device 16. For example, when the environmental information acquisition device 16 is an illuminance sensor, the illuminance is acquired as the environmental information. When the environment information acquisition device 16 is a sound sensor, the sound volume is acquired as environment information.

  The illumination control unit 114 controls the illumination system 20. The illumination system 20 in the present embodiment includes a first illumination device 22, a second illumination device 24, and a third illumination device 26. As a light source of each lighting device, for example, an LED (light emitting diode) is used.

  As shown in FIG. 1, the first lighting device 22 is a lighting device installed in a stand shape, for example, and can emit “strong” light. For example, by using the first lighting device 22, the illuminance hitting the user's eyes becomes 2500-5000 lux or more.

  As shown in FIG. 1, the second lighting device 24 is a lighting device installed on a bed board (head side), for example, and can emit “medium” light. For example, by using the second lighting device 24, the illuminance hitting the user's eyes becomes 0-500 lux.

  As shown in FIG. 1, the third lighting device 26 is a lighting device installed on the lower side of a bed device such as a bed frame of the bed device, and can emit “small” light. For example, by using the third lighting device 26, the illuminance hitting the user's eyes is 0-1 lux, and a preferable example is 0.3 lux.

  That is, the light intensity (luminous intensity / light flux) of each lighting device is such that the first lighting device 22> the second lighting device 24> the third lighting device 26 (the first lighting device 22> the third lighting device 26). It is configured. In addition, since it is only necessary that the brightness of the lighting device can be switched in stages, the lighting control unit 114 may change the brightness of the lighting device installed in the room, for example. In addition, the first lighting device 22 may not necessarily be greater than the second lighting device 24. That is, the light from the second lighting device 24 may be increased.

  Further, the first lighting device 22 and the second lighting device 24 may have substantially the same brightness. In this case, when the intensity of light is increased (when the illumination device is “large”), both the first illumination device 22 and the second illumination device 24 are turned on. When the intensity of light is medium (when the illumination device is “medium”), either the first illumination device 22 or the second illumination device 24 is turned on.

  The storage unit 120 stores various programs and various data necessary for the operation of the control device 10. The storage unit 120 includes, for example, a solid state drive (SSD) that is a semiconductor memory, a hard disk drive (HDD), or the like.

  Moreover, the memory | storage part 120 has ensured the area | region of the user information storage area 122 which memorize | stores user information, and the sleep state memory area | region 124 which memorize | stores a sleep state, and has memorize | stored the illuminating device parameter 126. FIG.

  The user information stored in the user information storage area 122 stores information related to the user. In the present embodiment, as shown in FIG. 3A, the user's scheduled activity time (for example, “07:30 to 21:00”) is added to the ID (for example, “PB001”) for identifying the user. ), Average sleep time (for example, “7 hours 35 minutes”), and other data necessary for processing are stored.

  The scheduled activity time is the time when the user should be in an awake state. The scheduled activity time is a time set by the scheduled activity time setting unit 102. The processing of the scheduled activity time setting unit 102 will be described later.

  The average sleep time is an average of the user's sleep time. The sleep time may be the time from the sleep time to the wake-up time, or the total time of the sleep state in the sleep time to the wake-up time. The average sleep time may be an average of several days, or may be an average of a period such as a weekly unit or a monthly unit.

  Here, the sleep time is the time when the user shifts to the sleep state. For example, it is the time at which the stability of body movement is detected from the sensor device 14 from the time when the user goes to bed, and the sleep state determination unit 106 determines that the sleep state is shifted to.

  The wake-up time is, for example, a time when body motion is detected from the sensor 14 when the user is in a sleep state, and the sleep state determination unit 106 determines that the state has shifted to an awake state. The sleep time may be the time when the user is in bed (the bedtime). The wake-up time may be the time when the user leaves the floor. Further, by setting the case where the user's arousal state is maintained for a predetermined period as the wake-up time, it is possible to exclude midway awakening.

  Data necessary for other processing is stored as appropriate. For example, biometric information values such as heart rate and respiratory rate that increase by unit time may be stored, or an average of biometric information values may be stored. Moreover, the sleep time for every day may be memorize | stored and a user's bed leaving time may be memorize | stored. The data necessary for the following description will be described as being appropriately included in the user information and stored.

  The sleep information stored in the sleep state storage area 124 stores the sleep state of the user. As shown in FIG. 3B, sleep information is associated with a date and time (for example, “2018/05/28 01:00”) for each ID for identifying a user (for example, “ "Sleep") is remembered.

  The illumination device parameter 126 stores brightness (for example, light flux, current value, level, etc.) for each illumination device of the illumination system 20. Thereby, the 1st illuminating device 22, the 2nd illuminating device 24, and the 3rd illuminating device 26 determine how much brightness is irradiated.

  The display unit 130 is a display device for displaying various information. For example, it is realized by a display device using an LCD or an organic EL display. In addition, the operation unit 135 receives an operation instruction from the subject. For example, in the case of a touch panel integrated with the display unit 130, it may be realized by a software key, or a hard switch may be provided.

  The alerting | reporting part 140 is an apparatus which alert | reports to a subject based on a signal and an interruption process. For example, it is possible to perform notification by vibration by a vibration device, notification by sound output by a buzzer, notification by light, and the like.

  The voice input / output unit 145 is a device that can input / output voice. For example, it can be realized by voice input by a microphone or voice output by a speaker.

  The display unit 130, the operation unit 135, the notification unit 140, and the voice input / output unit 145 may be built in the control device 10 or may be realized by an external device. Moreover, you may utilize the function of the operating device provided in the stand apparatus 30, and the function of the smart phone which the subject uses.

  In the communication unit 150, the control device 10 communicates with an external device or an external server device. The communication unit 150 can provide a plurality of communication IFs. For example, the communication unit 150 can perform communication using various methods such as Bluetooth (registered trademark), USB, wireless LAN (WLAN), and ZigBee (registered trademark). Moreover, you may communicate with an external server apparatus by systems, such as LTE / 5G.

[1.3 Examples]
Hereinafter, an example in the case of the configuration of FIG. 2 will be described for each process.

[1.3.1 First Example]
[1.3.1.1 Purpose of this embodiment]
Generally, when a user is present on a bed apparatus, the amount of activity falls. For this reason, in spite of the daytime period (activity scheduled time) which should have been waking up originally, the arousal level fell and there existed a subject that it changed to a sleep state.

  If the user continues to sleep for a long time in the daytime, the user will have a bad influence on the original sleep, such as poor sleep and a shallow sleep at night.

  Therefore, the present embodiment aims to maintain the user's arousal state by giving necessary stimulation to the user as needed within the scheduled activity time.

  Thereby, the support system which can support a user's sleep appropriately will be provided.

[1.3.1.2 Process flow]
(1) Main Processing FIG. 4 is a diagram for explaining the flow of processing in the first embodiment. The planned activity time is set by the planned activity time setting unit 102 (step S1002). The scheduled activity time setting process will be described later.

  Subsequently, the control unit 100 determines whether the sleep time of the user is appropriate (step S1004).

  As an example, the sleep time of the previous day (that is, the sleep time from the wake-up time of the day to the sleep time of the sleep section) and the average sleep time (for example, the average value of the sleep time for one week) are compared. And the control part 100 will determine with a user's sleep time being appropriate, when the sleep time of the previous day can be ensured from the average sleep time from predetermined threshold time. Specifically, when the average sleep time is “6 hours”, when the sleep time of the previous day is “5 hours 30 minutes” or more, the control unit 100 determines that the sleep time is appropriate.

  In addition, when the sleep time of the user is simply included in the set ideal sleep time range (for example, “5 hours to 7 hours”), the control unit 100 is appropriate for the sleep time. May be determined. In addition, when the sleep time of the previous day is far from the predetermined range from the average sleep time, the control unit 100 may determine that the sleep time is not appropriate. For example, when the sleep time of the previous day is more than “3 hours” or more than the average sleep time, the sleep time is not appropriate, and other processing may be executed (step S1004; No).

  And when sleep time is not suitable, this process is complete | finished or another process is performed (step S1004; No).

  Subsequently, when the user's sleep is detected (step S1006; Yes), the control unit 100 determines whether the time when the sleep is detected is within the scheduled activity time (step S1008).

  When the time when the sleep is detected is within the range of the scheduled activity time, the control unit 100 determines whether the biological information value is in the normal range (step S1010). Here, the biometric information value is a value related to the vitals of the user, such as a heart rate, a respiratory rate, a body temperature, and the like.

  If the biometric information value of the user is not within the normal range, the control unit 100 executes another process because an abnormality has occurred in the user (step S1010; No). For example, the control unit 100 ends this processing, or the control unit 100 (notification unit 140) executes notification processing. Further, the control unit 100 may call a nurse call via the communication unit 150.

  When it is determined in step S1010 that the biometric information value is included in the normal range, the control unit 100 executes an arousal control process to awaken the user (step S1012). The awakening control process may be executed until awakening is detected (step S1014; No). The awakening control process will be described later.

  Further, when the control unit 100 detects the user's sleep falling within the scheduled activity time (step S1008; No), the state of the bed device (for example, the back-up state) and the state of the lighting system 20 (for example, the lighting device) Lighting state). Specifically, when the bottom of the bed apparatus is in the back-up state, the control unit 100 sets the back bottom to be flat (back angle “0 degree”). Moreover, the control part 100 turns off an illuminating device, when any illuminating device is lighted (step S1016; Yes-> step S1018).

  Note that step S1018 is an example, and may be in another state. For example, the back angle may be set to “5 degrees”, and the lighting device may be turned “small” (the third lighting device 26 is turned on).

  And if the control part 100 detects a user's awakening (step S1014; Yes) (step S1020; Yes), it will wait for a user's sleep detection again (step S1006).

  In addition, when it becomes the next day (for example, when the date is changed, when the transition is from the scheduled activity time to the scheduled activity time, etc.), the control unit 100 once ends this processing and performs the processing from step S1002 again. May be executed.

(2) Scheduled Activity Time Setting Process The scheduled activity time setting process in step S1002 of FIG. 4 will be described with reference to FIG. The control unit 100 (scheduled activity time setting unit 102) acquires the sleep time of the previous day (step S1102). Here, the sleep time of the previous day refers to the time from the wake-up time of the day to the sleep time of the previous day.

  Subsequently, the control unit 100 (activity scheduled time setting unit 102) acquires an ideal sleep time (step S1104). Here, the ideal sleep time is an ideal sleep time as a user's sleep time.

  For example, it may be acquired from a cloud server device or may be acquired from another device. In the server device, the sleep time is totaled from a plurality of users, and the ideal sleep time is calculated. The ideal sleep time may be calculated in association with a plurality of items such as age (age), sex, and medical condition. Then, the scheduled activity time is set from the sleep time of the previous day and the ideal sleep time (step S1106).

  For example, the control unit 100 sets the scheduled activity time from the wake-up time of the day and the ideal sleep time in the sleep time of the previous day. Specifically, the time excluding the ideal sleep time of the day is considered as the scheduled activity time, and the scheduled activity time may start from the wake-up time of the day. In addition, when the sleep is shorter / longer than the ideal sleep time, the scheduled activity time may be changed.

  Thereafter, when the setting input of the scheduled activity time is input from the subject (mainly the administrator) (step S1108; Yes), the control unit 100 sets the input scheduled activity time (step S1110).

  As described above, in the processing example of FIG. 5, the scheduled activity time can be automatically set, but the target person may be able to set the actual scheduled activity time thereafter.

  The scheduled activity time may be set based on the user's history. FIG. 6 shows another operation flow of the scheduled activity time setting process.

  The control unit 100 determines whether the storage unit 120 stores enough days for the sleep state (sleeping time) history to determine the target sleep time (step S1202). And when the history of a sleep state is memorized (Step S1202; Yes), control part 100 acquires target sleep time. And the control part 100 sets activity scheduled time based on the acquired target sleep time (step S1204).

  Here, the control unit 100 may simply calculate the target sleep time according to the average value of the sleep time or according to the weight. Further, the control unit 100 may acquire the target sleep time using machine learning or a neural network based on various parameters such as a sleep state (history of sleep time), a biological information value, and bed and bed time. Good.

  Thereafter, when the setting input of the scheduled activity time is performed from the target person (mainly the administrator) (step S1206; Yes), the control unit 100 sets the input scheduled activity time (step S1208).

  The scheduled activity time is a time zone in which the user is preferably awake. Therefore, it may be other than simply setting the time range.

  FIG. 7 is an example of a display screen W100 in which the scheduled activity time can be set. Control unit 100 sets the scheduled activity time in the range of the scheduled activity time input on display screen W100.

  In addition to this, for example, on the display screen W100, the scheduled activity time can be set based on the following time zone and operation.

・ Range of predetermined time after meal (after lunch, after dinner, etc.) ・ When bed is in operation. For example, when reading mode or meal mode is selected, when the back-up angle is abnormal, or when using other devices such as watching TV

  In addition to the scheduled activity time, the control unit 100 can set the time for the user to wake up based on the above-described time range and the state and relationship of other devices.

(3) Awakening Control Processing The awakening control processing in step S1012 in FIG. 4 will be described with reference to an example of the operation flow in FIG.

  In order to wake the user, the motion stimulus has a strong influence as an external stimulus. Therefore, the control unit 100 will explain an example in which the user is awakened from a relatively weak stimulus of light and sound.

  The control unit 100 first turns on the first lighting device 22 that is the lighting device (large). Further, the control unit 100 outputs a notification sound from the notification unit 140 (step S1304). Note that voice may be output from the voice input / output unit 145.

  Further, the control unit 100 changes the process (bed motion) depending on whether or not the user's posture can be detected. Specifically, when the bed apparatus 5 is not equipped with a posture detector, the control unit 100 performs a back-lowering operation with less risk of raising the back due to the sleeping posture. Specifically, the control unit 100 (bed control unit 104) controls the bed control device 12 and executes a back-lowering operation (step S1306; No → step S1310).

  When the bed apparatus 5 is equipped with a posture detector, the control unit 100 performs a back raising operation (step S1306; Yes → step S1308). For example, the control unit 100 does not perform the back-up operation when the user is in the recumbent position, but performs the back-up operation when the user is in the supine position.

  And the control part 100 performs control of the 1st illuminating device 22 of step S1302, the output of the alerting sound from the alerting | reporting part 140 of step S1304, and the control of the bed operation | movement by the bed control apparatus 12 of step S1308 / S1310 collectively. It may be performed step by step. For example, when the user does not transition to the awake state, the process may be executed as step S1302 → step S1304 →. Further, step S1302 and step S1304 are performed together, and if the user still does not wake up, the bed operation may be controlled.

  Moreover, the control part 100 may each perform the operation | movement mentioned above by the time difference instead of a user's awakening.

  For example, FIG. 9 is an example of a display screen W110 in which an awakening control operation can be set. On display screen W110, the user can set whether or not to perform the operations of “bed motion”, “alarm sound (notification sound)”, and “lighting”.

  In the display screen W110, the priority of the set operation can be set. Thereby, for example, the priority of the bed motion may be increased, and the target person (mainly the administrator) can set that the combination of the two actions is performed with priority. Specifically, the lighting device “large” (first lighting device 22) may be turned on after the bed motion operation is performed.

[1.3.1.3 Effect]
As described above, the first embodiment can appropriately awaken the user even if the user falls asleep during the time zone when the user is originally awake. Thereby, it is possible to prevent the user from sleeping unnecessarily at night or the quality of sleep from being reduced due to the user taking unnecessary sleep during the daytime or the like.

[1.3.2 Second Example]
[1.3.2.1 Purpose of this embodiment]
It is known that humans change their sleep cycle when exposed to light. However, if you are exposed to strong light when it is not appropriate, there is a problem that sleep falls.

  Therefore, the present embodiment aims to maintain a correct sleep cycle by irradiating a user with light at an appropriate timing.

[1.3.2.2 Process flow]
(1) Main Processing FIG. 10 is a diagram for explaining the flow of processing in the second embodiment. First, the control unit 100 executes a sleep / wake-up scheduled time setting process, and sets a planned sleep time and a planned wake-up time. The scheduled sleep time is a time that is a target for the user to sleep. The scheduled wake-up time is a target time for the user to wake up. This sleep / wake-up scheduled time setting process will be described later.

  The control unit 100 (sleep state determination unit 106) detects the user's getting up (step S1404). The control unit 100 determines whether or not the wake-up time when the wake-up is detected is within the scheduled wake-up time (step S1406). Here, the scheduled wake-up time refers to the time after the scheduled wake-up time set in step S1402 (time from the scheduled wake-up time to the scheduled sleep time). For example, when the scheduled sleep time is set to “22:00” and the scheduled wake-up time is set to “7:00”, “7:00” or later is set as the scheduled wake-up time. The scheduled wake-up time is from the scheduled wake-up time to the scheduled sleep time, but may be, for example, a predetermined time (for example, 5 hours) from the scheduled wake-up time.

  The scheduled wake-up time may have a predetermined time width. For example, when the scheduled wake-up time is set to “7:00”, the scheduled wake-up time may include around “30 minutes” as the time width. Therefore, in this case, the start time of the scheduled wake-up time may be after “6:30”.

  If the wake-up time is not within the scheduled wake-up time, the control unit 100 (lighting control unit 114) switches the lighting system 20 to the nighttime lighting mode (step S1406; No → step S1408). That is, the lighting device “small” is turned on (only the third lighting device 26 is turned on).

  Subsequently, the control unit 100 executes the awakening correction mode or the awakening mode depending on whether the wake-up time is included in the predetermined correction condition.

  Specifically, when the wake-up time is within the scheduled wake-up time, the control unit 100 determines whether the wake-up time is before “12:00” (step S1410). When the user has woken up before “12:00”, that is, when the wake-up time is before “12:00”, the control unit 100 determines whether the time is delayed by the determination time from the scheduled wake-up time. (Step S1410; Yes → Step S1412).

  Here, the determination time is a predetermined value such as “30 minutes” or “1 hour”, for example. The determination time may be set by the subject or may be automatically set according to the sleep cycle of the user.

  When the wake-up time is delayed by the determination time from the scheduled wake-up time (step S1412; Yes), the control unit 100 (environment information acquisition unit 112) measures the brightness of the environmental light via the environment information acquisition device 16 (step S1412). S1414).

  Here, when the ambient light is not brighter than 2500 lux (step S1416; No), the control unit 100 (illumination control unit 114) executes the awakening correction mode (step S1418). In the awakening correction mode, the lighting devices “medium” and “large” (that is, the first lighting device 22 and the second lighting device 24) are turned on.

  Also, when the wake-up time is “12:00” or later (step S1410; No), when the determination time is not delayed from the scheduled wake-up time (step S1412; No), or the brightness of the ambient light is measured, it is 2500 lux or more When the brightness is ensured (step S1416; Yes), the control unit 100 (illumination control unit 114) executes the awakening mode (step S1420). In the awakening mode, the lighting device “medium” (that is, the second lighting device 24) is turned on.

  In addition, as a means to irradiate a user, for example, sunlight is given priority, and ambient light is measured in step S1414, but ambient light may not be measured. That is, the control unit 100 may execute the awakening correction mode regardless of the brightness of the ambient light.

  Moreover, in the Example mentioned above, although the 1st lighting device 22 and the 2nd lighting device 24 are used as awakening correction mode, the brightness should just be changed. For example, the same effect can be obtained by changing the brightness of one lighting device provided on the ceiling.

  Regardless of the lighting device, for example, when the communication unit 150 is connected to a control device that controls the curtain in the room, the control unit 100 controls to open the curtain in the room instead of controlling the lighting device. May be combined.

  In addition, the control unit 100 acquires weather information from an external server via the communication unit 150, performs control to open a curtain when sunlight can be secured, and performs irradiation with a lighting device when sunlight cannot be secured. May be performed.

  Moreover, although the control part 100 demonstrated controlling the illuminating device in night illumination mode, awakening correction mode, and awakening mode, you may control a bed apparatus collectively. For example, the control unit 100 (bed control unit 104) may flatten the bed apparatus (do not raise the back) in the night illumination mode, and perform the back raising control in the awakening correction mode or the awakening mode. Further, the control unit 100 may perform only the control of the bed apparatus (only the back raising control) in the awakening correction mode / awakening mode.

(2) Sleep / Wake-up Schedule Time Setting Process The sleep / wake-up schedule time setting process in step S1402 of FIG. 10 will be described with reference to FIG. First, the control part 100 acquires a user's sleep time (for example, the sleep time of the previous day) (step 1502). Subsequently, the control unit 100 acquires an ideal sleep time (step S1504). Acquiring the ideal sleep time is the same process as step S1104 in FIG.

  Thereafter, the control unit 100 sets the sleep / wake-up scheduled time from the sleep time of the previous day and the ideal sleep time (step S1506).

  For example, the control unit 100 refers to the sleep time and the wake-up time in the sleep time of the previous day, and sets the sleep / wake-up time so that the ideal sleep time can be secured. Moreover, the control part 100 is good also considering the time which passed ideal sleep time from the actual sleep time as a scheduled wake-up time.

  As described above, in the process of FIG. 11, the sleep / wake-up scheduled time can be automatically set, but the target person may then set an arbitrary time as the sleep / wake-up scheduled time.

  Note that the sleep / wake-up scheduled time may be set based on the user's history. FIG. 12 shows another operation flow of the sleep / wake-up scheduled time setting process.

  The control unit 100 determines whether the storage unit 120 stores enough days for the sleep state (sleeping time) history to determine the target sleep time (step S1602). And when the history of sleep state is memorized (Step S1602; Yes), control part 100 acquires target sleep time. And the control part 100 sets sleep / wake-up scheduled time based on the acquired target sleep time (step S1604).

  Here, the method by which the control unit 100 acquires (calculates) the target sleep time is the same as the method described in FIG.

  Thereafter, when the setting input of the sleep / wake up scheduled time is input from the subject (mainly the administrator) (step S1606; Yes), the control unit 100 sets the input sleep / wake up scheduled time (step S1606). S1608).

[1.3.2.3 Effect]
As described above, according to the present embodiment, the user is irradiated with light with high illuminance at an appropriate timing by using an illumination device or the like. As a result, the amount of daytime activity in the user is increased, and normal body rhythm can be maintained.

  In particular, when the user receives high-intensity light before 12:00 (for example, 2500 LX), the internal rhythm advances, but when the user receives high-intensity light after 12:00, the internal rhythm moves backward. Resulting in. In the present embodiment, in consideration of this point, the user is irradiated with light with high illuminance at an appropriate timing.

  FIG. 13 is a diagram for explaining the operation of this embodiment. For example, a scheduled wake-up time t12 to a planned sleep time t18 are set as ideal activity time zones (scheduled activity time). Assume that a user falls asleep last night at time t20 and wakes up at time t16.

  In this case, the awakening correction mode is executed when the user wakes up by 12:00 from t14 delayed by the determination time from the scheduled wake-up time t12. Since the wake-up time t16 in FIG. 13 is included in the range, the awakening correction mode is executed.

[1.3.2.4 Separate processing]
In the above-described embodiment, in step S1410, switching between the awakening correction mode and the awakening mode is performed depending on whether it is before 12:00.

  However, the scheduled wake-up time is not always set in the morning. In this case, as shown in FIG. 14, it may be determined whether there is a deviation from the average sleep time of the user instead (step S1452 in FIG. 14).

  That is, when the sleep time of the previous day is little different from the average sleep time, it may be a process that the sleep time is considered to be late and the transition to the awakening correction mode is not made.

  Note that the operation flow of FIG. 14 is obtained by replacing a part of the operation flow of FIG. Therefore, processes other than step S1452 different from the process flow of FIG. 10 are the same.

[1.3.3 Third Example]
[1.3.3.1 Purpose of this embodiment]
In the prior art, the bed device and the lighting device are not linked. For example, when the user raises his / her back for reading, it is necessary to operate the lighting device by himself along with the back raising operation. Further, if the lighting device is turned on only by the user's operation, there arises a problem that the lighting device is turned on with an inappropriate brightness when the user is awakened halfway.

  Therefore, the present embodiment aims to link the control of the bed apparatus and the control of the lighting apparatus.

[1.3.3.2 Process flow]
FIG. 15 is a diagram for explaining the flow of processing in the third embodiment. The control unit 100 (bed control unit 104) detects whether the back is raised or the back is raised (step S1702).

  Here, the back-up operation is performed according to a predetermined operation by the user. The back-up operation may be an operation input such as “back-up” or “back-down” or may be performed according to the mode. The bed control device 12 performs operations of the back bottom, the knee bottom, and the foot bottom according to a plurality of modes such as a bed leaving mode, a reading mode, a meal mode, and a chair mode, for example.

  Subsequently, the control unit 100 determines whether or not the user leaves the floor (step S1704). Here, whether or not the user leaves the floor is determined by various methods. As some examples, the following methods can be considered.

  The control unit 100 predicts getting out of the bed based on the position of the user of the sensor device 14. For example, when the user moves to the end of the bed apparatus and takes an end sitting position, the control unit 100 predicts that the user will get out of the bed apparatus.

  -The control part 100 performs bed leaving prediction based on a mode. For example, when the user selects “bed-off mode”, “transfer mode”, or the like as the bed device mode, the control unit 100 determines that the user leaves the bed. In addition, when “reading mode”, “meal mode” or the like is selected by the user, the control unit 100 determines that the user does not get out of the bed apparatus.

  -Another bed sensor may be provided and the control unit 100 may perform bed prediction based on the bed sensor. For example, the position of the user is determined by a pressure sensor, an infrared sensor, an ultrasonic sensor, a camera, or the like, and the control unit 100 performs bed prediction.

  Here, when the user does not get out of the bed apparatus, the control unit 100 (lighting control unit 114) turns on the lighting device “middle” (second lighting device 24) (step S1704; No → step S1714).

  On the other hand, when it is determined that the user leaves the bed device, the control unit 100 (lighting control unit 114) turns on the lighting device “small” (third lighting device 26) (step S1704; Yes → step S1706). Then, it waits until the user leaves and stays again (step S1708).

  Thereafter, when the control unit 100 (the bed control unit 104) detects back-lowering (step S1708; Yes → Step S1710; Yes / Step S1714 → Step S1710; Yes), the lighting device that is currently lit is turned OFF. The process returns to step S1702 again (step S1712 → step S1702).

  The lighting device (lighting system 20) may be turned on / off by the user during the process. In this case, the control unit 100 may end this process at that time.

[1.3.3.3 Effect]
Thus, according to the present Example, the brightness of an illuminating device can be switched appropriately according to control of a bed apparatus and a user's state. In this way, the user can be supported appropriately by providing appropriate illumination brightness for the user.

[2. Second Embodiment]
Next, a second embodiment will be described as another embodiment of a system for supporting a user. In hospital rooms and homes, various things are placed around the bed apparatus, which causes a problem that it is difficult for users to take out things. In addition, it was necessary to sort out the items placed by medical workers, staff, and families, which was a heavy burden.

  In recent years, in addition to conventional medical devices, a monitor for confirming a user's state and information transmission is often installed, and a terminal device used by the user is often arranged.

  Therefore, when a plurality of objects are arranged, there is a problem that it is difficult to arrange and manage these objects.

  In view of these problems, an object of the present embodiment is to provide a system that supports a user by using a stand as a hub and providing the stand with various functions.

[2.1 Outline of the stand]
The outline | summary of the stand apparatus 30 is demonstrated based on FIG. FIG. 16A is a perspective view of the stand device 30, and FIG. 16B is a front view of the stand device 30.

  The stand device 30 is configured such that various units can be freely attached to one or a plurality of support columns 38. Each unit and the column 38 are attached by, for example, fitting the convex portion of each unit into the concave portion provided in the column 38. Further, each unit may be attached to the hole provided in the column 38 by screwing. Moreover, you may attach the support | pillar 38 and each unit by magnetic force.

  The unit is composed of a plurality of types. For example, FIG. 16 shows, as an example, a lighting unit 31, a storage unit 32, a display unit 33, a gripping unit 34, a trash box unit 35, and a storage unit 36 from the top.

  The foot portion 37 has a power supply device. The stand device 30 is configured to be able to supply power to each unit from the power supply unit through the support column 38. For example, the illumination unit 31 is provided with an LED light and is supplied with power from a power supply unit.

  The storage unit 32 stores a stand part 32a and a power supply part 32b. The stand part 32a is a part on which a smartphone or the like can be placed.

  The power supply part 32b is a part for supplying power to a smartphone or the like. For example, it has a power supply port in the shape of a USB terminal capable of outputting 5 V and a power supply port in the shape of an outlet capable of outputting 100 V.

  In addition to this, a table unit that can use a rotating top plate as a table, a wireless charging unit that provides wireless charging, a voice input / output unit with a built-in microphone and speaker, and a user's body temperature A temperature sensor unit equipped with a thermometer capable of measuring the temperature, a photographing unit capable of photographing and recording a user's condition, and the like can be attached.

  Further, an illumination part that illuminates the feet may be attached to the bottom of the storage unit 36. In this case, the storage unit 36 is preferably attached to the lowermost part. Also. The illumination part may be attached to the foot 37, for example.

[2.2 Functional configuration]
Next, the functional configuration with the stand device 30 as the center will be described with reference to FIG. The functional configuration of FIG. 17 is a functional configuration when each unit is arranged on a stand. Therefore, when the unit is not attached, the corresponding configuration is also unnecessary.

  In the present embodiment, a description will be given assuming that a control unit is built in the stand device 30. However, as in the first embodiment, it may be realized in another control device such as a tablet or a computer.

  The stand device 30 includes a control unit 300, a storage unit 320, a communication unit 350, and a driving device 370, and if necessary, a display unit 330, an operation unit 332, a notification unit 334, and a lighting device. 340, an environment information acquisition device 360, a failure detection device 380, a photographing device 382, a voice input / output device 384, and a power feeding device 386.

  The control unit 300 controls the entire stand device 30. The control unit 200 is one or more arithmetic devices (for example, a CPU (Central Processing Unit)) that realizes various functions by reading and executing various programs stored in the storage unit 220.

  The control unit 200 reads out and executes the program stored in the storage unit 220, whereby the sleep state determination unit 302, the bed leaving determination unit 304, the biological information value acquisition unit 306, the drive control unit 308, the position determination unit 310, It functions as a bed control unit 312, a lighting control unit 314, and an environment information acquisition unit 316.

  The biometric information value acquisition unit 306 acquires the biometric information value of the user. The sleep state determination unit 302 determines the sleep state of the user and stores the sleep state in the sleep state storage area 324. The bed leaving determination unit 304 determines whether the user is getting out of bed / being present, or determines whether to get out of bed. The bed / bed state determined by the bed leaving determination unit 304 may be stored in the sleep state storage area 324.

  Here, the functions of the sleep state determination unit 302 are the sleep state determination unit 106 of the first embodiment, the bed leaving determination unit 304 is the bed leaving determination unit 108, and the biological information value acquisition unit 306 is the biological information value acquisition of the first embodiment. The function is substantially the same as that of the unit 110.

  The drive control unit 308 controls the drive device 370 for the stand device 30 to travel autonomously. The drive device 370 includes a travel drive unit 372 for the stand device 30 to travel back and forth, left and right, a height drive unit 374 that changes the height of the stand device 30, and a unit drive unit 376 that operates the unit. doing.

  For example, the travel drive unit 372 is configured by connecting a drive motor to a tire (wheel) provided at the lower portion of the stand device 30. When the drive device 370 (travel drive unit 372) receives a drive control signal from the drive control unit 308, the drive device 370 moves forward and backward. Further, it is possible to change the direction by controlling a plurality of wheels or changing the direction of the wheels. As a result, the stand device 30 can move back and forth and right and left on the floor surface.

  The height driving unit 374 is configured by connecting an actuator to a link mechanism. When the drive device 370 (height drive unit 374) receives the drive signal from the drive control unit 308, the drive device 370 operates to change the height.

  The unit driving unit 376 is a driving device provided for each unit. Upon receiving drive control from the drive control unit 308, the drive device 370 (unit drive unit 376) operates the unit. For example, it is possible to move the table top, change the direction of the display unit (display device), or open and close the lid of the storage unit.

  The drive control unit 308 is connected to the failure detection device 380. The obstacle detection device 380 is a device that detects whether there are obstacles on the front, rear, left and right of the stand device 30. As a method for the obstacle detection device 380 to detect an obstacle, the obstacle may be detected by a radar method, or the obstacle may be detected by a camera. Further, the obstacle detection device 380 may detect an obstacle on the bed device or may detect an obstacle on the upper surface.

  The drive control unit 308 stops the operation of the drive device 370 when receiving from the failure detection device 380 that an obstacle has been detected. Thereby, when there is an obstacle in the moving direction of the stand device 30, the operation is stopped, so that it can be operated safely.

  The position determination unit 310 determines the position of the stand device 30. The position determination unit 310 determines the position of the stand device 30 based on the position information stored in the position information determination table 326 of the storage unit 320.

  FIG. 18 is a diagram schematically illustrating the movement area of the stand device 30. 18A is a plan view seen from above, and FIG. 18B is a side view seen from the side.

  As shown in FIG. 18A, the stand device 30 can move in the region (range) of p1 along the longitudinal direction of the bed device 5. Further, when the save area EE can be secured, it may be possible to move in the area p2, for example. The position information determination table 326 stores the position to which the stand device 30 is moved within the movable area.

  Further, the position information determination table 326 can store the movable range of the unit. For example, the fact that the top plate of the table unit can move within the range of p3 is stored as a movable range. Further, the position information determination table 326 stores the position at which the top plate should be in accordance with the operation mode.

  FIG. 18B shows the height as the moving area of the stand. That is, the stand device 30 can change the height in the region of p5. Further, the height of the entire stand device 30 may be changed, or the height may be changed for each unit. Moreover, you may change the height of the apparatuses (for example, a display apparatus, a top plate, etc.) provided in the unit.

  In order for the position determination unit 310 to determine the position of the stand device 30, it is determined with reference to the position information determination table 326, or the position determination unit 310 calculates and determines the position.

  For example, FIG. 19A is a diagram illustrating an example of the position information determination table 326. The position information determination table 326 is arranged along the longitudinal direction when the position of the stand device 30 (for example, the position of the head side of the bed device 5 is “0” cm) according to the operation and the back angle (back bottom angle). And the height (for example, the height when the lowest height of the stand device 30 is “0” cm) are stored. Then, the position determination unit 310 determines the position and height of the stand device 30 according to the back angle (back raising angle) that is the state of the operation and the bed device 5.

  For example, when the back angle of the bed apparatus 5 is “20 degrees”, the position determination unit 310 determines the position of the stand apparatus 30 as “20 cm” and the height as “10 cm”. Then, the drive control unit 308 drives the drive device 370 so that the stand device 30 is located at the position determined by the position determination unit 310.

  When the operation mode of the bed apparatus 5 is “meal mode”, the position determination unit 310 determines the position of the stand device 30 as “40 cm” and the height as “20 cm”. When the table unit is connected, the top plate is determined to be the meal position. Then, the drive control unit 308 drives the drive device 370 so that the stand device 30 is located at the position determined by the position determination unit 310.

  The position determination unit 310 may determine the position by calculation. FIG. 19B is a diagram for schematically explaining the position of the stand device 30. In this figure, the back bottom 51, the waist bottom 52, the knee bottom 53, and the foot bottom 54 of the bed apparatus 5 are schematically shown. In addition, this figure demonstrates mainly the back raising operation | movement (back-lowering operation | movement).

  When the user lies on the bed apparatus 5, for example, it is determined that the stand apparatus 30 is positioned at the position h. Then, the position of the stand device 30 can be calculated based on the back angle θ.

  For example, when the back angle is “0 degree”, the stand device 30 is located at the position of p10. However, when the back angle is “θ1 degree”, the stand 30 is at the position of p12 and the back angle is “θ2”. When, the stand 30 is calculated so as to be at the position of p14.

  Thus, the position determination unit 310 can calculate and determine the position of the stand device 30 according to the back angle. In addition, the position determination unit 310 can also calculate and determine the height of the stand device 30 according to the back angle.

  The bed control unit 312 can control the bed control device 12 via the communication unit 350. It is also possible to acquire the state of the bed. The illumination control unit 314 can control the illumination device 340.

[2.3 Examples]
Hereinafter, an example in the case of the configuration of FIG. 17 will be described for each process.

[2.3.1 Fourth Example]
[2.3.1.1 Purpose of the present embodiment]
In general, for example, a table installed on the side of the bed apparatus is manually moved. Therefore, when using the stand shown in FIG. 16 according to the posture and position of the user, the user needs to ask the nurse or staff to move each time.

  In addition, there are a plurality of necessary items for users, and the types differ depending on the users. Therefore, various objects are left apart for each user, and there is a possibility that they cannot be organized.

  Therefore, the present embodiment aims to provide a stand device whose position changes depending on the movement of the user and the state of the bed device.

[2.3.1.2 Process Flow]
(1) Main Processing FIG. 20 is a diagram for explaining the flow of processing in the fourth embodiment. The control part 300 (sleep state determination part 302) detects a user's getting up (step S2102; Yes). When the user's wake-up is detected, the control unit 300 (the bed leaving determination unit 304) determines whether or not the user has left the bed (step S2104). When there is a bed leaving operation, processing corresponding to the bed moving operation is executed as appropriate, but the processing is terminated in this embodiment.

  If there is no bed leaving operation (step S2104; No), the control unit 300 (bed control unit 312) changes the state of the bed apparatus 5 to a predetermined state (step S2106). For example, the control unit 300 (the bed control unit 312) moves the back bottom so that the back angle input from the user is obtained, or the bed apparatus according to the operation mode (for example, the meal mode) selected by the user. Or move the bottom of the.

  Subsequently, the control unit 100 (position determining unit 310, drive control unit 308) executes a stand device positioning process for determining the position of the stand device 30 (step S2108). The stand device positioning process will be described later. By executing the stand device positioning process, the position of the stand device 30 is determined, and the stand device moves to an appropriate position.

  After the stand device 30 is moved to an appropriate position in step S2108, the control unit 300 determines whether or not information needs to be displayed on the display unit 330 (step S2110). Here, when it is necessary to display information on the display unit 330, the control unit 300 adjusts the height of the display unit 330 to a predetermined height (a height that can be visually recognized by the user) (step S2112). .

  FIG. 21 is a diagram for schematically explaining the height of the display unit 330. In FIG. 21, the display unit 33 is attached to the column 38 as the display unit 330.

  Here, in FIG. 21A, the back raising angle is “0 degree”. That is, the angle between the back bottom 51 and the bed frame is “0 degree”, and at this time, the display unit 33 is located in a low place.

  In FIG. 21B, the back-up angle is “30 degrees”. That is, the angle between the back bottom 51 and the bed frame is “30 degrees”. At this time, the display unit 33 is not visible to the user on the bed apparatus 5 at the position as it is.

  Therefore, by raising the height of the display unit 33 by h1, the display unit 33 is positioned at a position that is easily visible to the user.

  The visually recognizable height at which the user can visually recognize the display unit may be stored in the position information determination table 326. Moreover, the position determination part 310 may calculate based on a back raising angle.

  Returning to the processing in FIG. 20, when the bed apparatus 5 is in a state corresponding to the mode, the control unit 300 may perform an operation of moving the corresponding unit to a predetermined position (step S <b> 2114; Yes). → Step S2116).

  In the present embodiment, for example, when the bed apparatus 5 is in the “meal mode” state, the control unit 300 (drive control unit 308) moves the top plate of the table unit to a predetermined position (step S2116). .

(2) Stand Device Positioning Process The stand device positioning process in step S2108 of FIG. 20 will be described with reference to FIG. The control unit 300 (position determining unit 310) determines whether the current position of the stand device 30 is in the corresponding position (step S2202).

  Specifically, the current position of the stand device 30 is acquired, and it is determined whether the position is the same as the position stored in the position information determination table 326 or the position calculated by the position determination unit 310. Here, when the stand device 30 is not in the corresponding position, the control unit 300 (drive control unit 308) moves the stand device (step S2202; No → step S2204). At this time, if an obstacle is detected by the obstacle detection device 380, the movement of the stand device 30 is stopped (step S2206; Yes → step S2208).

  When the stand device 30 comes to the corresponding position, the control unit 300 (position determining unit 310) determines the height corresponding to the height of the stand device 30 (step S2210). Specifically, the current height of the stand device 30 is acquired, and it is determined whether the height is the same as the height stored in the position information determination table 326 or the height calculated by the position determination unit 310.

  Then, when the height of the stand device 30 becomes the corresponding height (step S2210; Yes), this process ends.

[2.3.1.3 Effects]
According to the present embodiment, the position and height of the stand device 30 are determined in accordance with the operation of the bed device (for example, back-up operation, mode selection, etc.). Then, the stand device 30 automatically transitions to the determined position and height.

[2.3.2 Fifth embodiment]
[2.3.2.1 Purpose of the present embodiment]
The stand device or the like is required to be on the bed device side so that the user can easily use it. However, when the user leaves the bed, the stand device is provided on the bed device side, which hinders the user's bed leaving operation.

  Accordingly, the present embodiment is intended to automatically move the stand device to a position where it does not become an obstacle to the bed leaving operation when the user leaves the bed.

[2.3.2.2 Process Flow]
FIG. 23 is a diagram for explaining the flow of processing in the present embodiment. As in the fourth embodiment, the control unit 300 (position determining unit 310) performs a positioning process of the stand device. In the present embodiment, description will be made mainly on the part of the bed leaving operation.

  When the control unit 300 (the bed leaving determination unit 304) detects the user's bed moving operation, the control unit 300 (the bed leaving determination unit 304) determines whether the stand device 30 is located in the retreat area. Here, the save position is, for example, a save area EE of 18 (a).

  If the stand device 30 is not at the position of the save area EE, the control unit 300 (position determining unit 310, drive control unit 308) executes a positioning process so that the stand device 30 moves to the position of the save area EE. (Step S2310). As a result, when the user leaves the floor, the stand device 30 moves to the waiting area.

  Then, when detecting the presence of the user, the control unit 300 (the bed leaving determination unit 304) acquires the state of the bed apparatus (step S2312; Yes → step S2304). Then, according to the state of the bed apparatus, the control unit 300 executes a stand apparatus positioning determination process (step S2306).

  It should be noted that the same process is executed even when the bed leaving movement is not detected (step S2302; No), and steps S2304 and S2306 may execute the process of the fourth embodiment.

  Moreover, in the Example mentioned above, although the control part 100 has detected the bed leaving operation | movement in step S2302, you may operate that a user performs a bed leaving operation. For example, it may be operated via the voice input / output device 384 by talking about getting out of the floor, or may be operated to perform the leaving action according to a predetermined action (for example, moving a hand). Good.

[2.3.2.3 Effects]
Thus, according to the present embodiment, when the user leaves the floor, the stand device 30 automatically moves to the waiting area. When the user is again on the floor, the stand device 30 performs an operation of returning to the position of the user.

  Accordingly, the stand device 30 is positioned at an appropriate position according to the user's bed leaving / floating state without hindering the user's bed leaving operation, and the user can be supported appropriately. .

[2.3.3 Sixth Example]
[2.3.3.1 Purpose of this embodiment]
Since the stand device 30 can be equipped with a plurality of units, for example, the camera can take a picture of the user sleeping. Accordingly, it is an object to detect anomalies in sleep such as snoring from photographing data and to perform cooperation with the bed apparatus 5.

[2.3.3.2 Process Flow]
FIG. 24 is a diagram for explaining the flow of processing in the present embodiment. First, when detecting the user's sleep, the control unit 300 records the state of the user with the photographing device 382 (step S2402; Yes → step S2404). Note that data (recording data) recorded by the photographing apparatus 382 is stored in the storage unit 320, for example.

  Subsequently, the control unit 300 detects an abnormality. Various methods are conceivable as a method for the control unit 300 to detect a user's change. For example, the following change is detected.

・ Sleep apnea syndrome caused by snoring, etc. ・ Sleep apnea syndrome caused by user's sleeping posture ・ S restless leg syndrome caused by user movement ・ Risk of falling due to user's sleeping position, etc. If detected, the bed motion is instructed (step S2410). For example, as bed motion, back-up / back-down operation, tilting operation by bed head / foot height control, and rolling support operation by air cell control are performed.

  The control unit performs these bed motion operations as necessary. For example, if it is support for turning over, it continues until the user turns over (step S2142; No).

  And the control part 300 continues a process until a user gets up (step S2414; No). The control unit 300 stops the recording after the user wakes up (step S2416).

  In the above-described embodiment, the control unit 300 uses the recording data by the photographing device 382 to detect an abnormality, but other data may be used. For example, the user's abnormality may be detected based on the biometric information value acquired by the sensor device 14, the audio data acquired by the audio input / output device 384, and the like.

  In addition, the control unit 300 may also notify the medical staff and staff via the communication unit 150 when detecting a user change.

[2.3.3.3 Effect]
Thus, according to the present embodiment, it is possible to provide a system that detects a user's change by the stand device 30 and interlocks with the bed device 5 to eliminate the user's change.

[2.3.4 Seventh Example]
[2.3.4.1 Purpose of this embodiment]
There is no cooperation between the stand, the hospital room where the bed apparatus 5 is installed, and other devices in the room. That is, the stand, the smart phone, and the equipment in the room are operating separately, and the operation cannot be controlled collectively.

  In the present embodiment, an object is to provide a user support system capable of cooperating with other devices using the stand device 30 as a hub.

[2.3.4.2 Process Flow]
FIG. 25 is a sequence diagram for explaining the concept of processing of the present embodiment. Hereinafter, a description will be given with reference to FIG.

  First, as a device for controlling the stand device 30 by a user, a smartphone (including a tablet, a computer, and a smart watch), a voice input / output device (for example, a smart speaker), and the like are assumed.

  For example, when an installation operation is instructed from a user to a smartphone, the smartphone installs a control application. Thereby, the user can give an instruction to the stand device 30 by giving an operation instruction to an application executed on the smartphone.

  For example, the user controls “illumination ON” using a control application executed on the smartphone. Then, the smartphone transmits a control signal “illumination ON” to the stand device 30.

  The stand device 30 transmits an illumination ON signal to the illumination device (illumination system 20) based on the received “illumination ON” signal. The illumination device turns on the illumination based on the illumination ON signal, that is, starts irradiation.

  Further, the user inputs a voice message “Display body temperature” on the voice input / output device. The voice input / output device determines that the voice input is an operation instruction for displaying the body temperature, and transmits a signal indicating the body temperature to the stand device 30. The stand device 30 transmits a signal for measuring body temperature to, for example, a thermosensor.

  The thermosensor measures the body temperature of the user and transmits the body temperature to the stand device 30 as a return value. The stand device 30 transmits the received body temperature to the display device. The display device performs body temperature display based on the received body temperature.

  In the present embodiment, the lighting device and the thermosensor have been described as examples of devices to be controlled. However, other devices such as a room air conditioner, a curtain operation, and a television operation can be used as long as they can cooperate with the stand device 30. Good.

  Moreover, although the smart phone and the voice input / output device have been described as examples, the stand device 30 may be directly operated. In particular, by connecting an electronic device such as a smartphone or a tablet to the power supply unit, the user can use the electronic device at an arbitrary position by moving the position of the stand device 30.

  In addition, by installing the nurse call application on the smartphone, the nurse call function can be realized via the smartphone.

[2.3.4.3 Effect]
According to the present embodiment, the stand device 30 can be used as a hub, and other devices can be controlled using a terminal device such as a smartphone or a tablet, or a voice input / output device such as a smart speaker. Thereby, for example, it becomes easy to operate even when the user is sleeping, and it is possible to support the user appropriately.

  Thereby, in cooperation with the state of the back raising / lowering operation of the bed apparatus 5 and detection of the user's arousal by the sensor apparatus 14, the vitals, sleep history, and time screen can be automatically displayed. In addition, when an abnormality of the user's body is detected, the nurse call menu screen can be automatically displayed or a notification can be made.
