The user put on the swing rack 10 is, for example, an infant. This user may be an infant (a child under 1 year old) or an infant (a preschooler aged 1 year or older).
The terminal device 20 is, for example, a mobile phone, a smartphone, a tablet, or the like, and communicates with the base main body 13 of the swing rack 10 via wireless or wired communication.

In the swing rack 10, the bed main body 12 swings in the longitudinal direction (left-right direction) in FIG. 1 with respect to the base main body 13 and functions as a rack portion. Thereby, user E, such as an infant, can be relaxed or can be brought to sleep.
The base main body 13 has a structure in which, for example, a mattress for a bed (not shown), a headrest, and the like are installed on a housing having a shape illustrated in FIG. Between them, the sensor 11 is arranged. The configuration including the sensor 11 and the base main body 13 can also be configured as a swing unit.

The sensor 11 is a sensor that detects biological information of the user E such as body movement, respiration, and pulse. As the sensor 11, for example, a piezoelectric element that detects vibration (pressure fluctuation) can be used.
This sensor 11 is a sheet-like sensor that detects biological information transmitted from the user E, such as body movement, breathing, and pulse, in a state of being arranged under the user E. The sensor 11 is disposed between the mattress and the headrest and the bed main body 12, but is not limited thereto, and may be disposed on the mattress and under the headrest, for example. However, other bedding may be interposed.
When the user E lies on the bed main body 12, body movement caused by various things including the breathing and heartbeat of the user E is detected by the sensor 11, and detection in which vibration components such as the heartbeat are superimposed is detected. A signal is output from the sensor 11 as the biological information of the user E.

Here, the swing rack 10 may be configured to include, for example, a display unit including a liquid crystal panel for image display and a driving circuit for the liquid crystal panel as a component other than the illustrated components. By adopting the configuration, it is also possible to present various types of information (for example, a set swing pace) to the user E's mother.
In the base main body 13, the acquisition unit 131, the communication unit 132, the control unit 134, and the sound source unit 136 may be configured by a processing device such as a CPU (Central Processing Unit) or a dedicated electronic circuit, for example. In addition, the acquisition unit 131, the communication unit 132, the control unit 134, and the sound source unit 136 may be configured by, for example, separate processing devices and electronic circuits, respectively. It may be configured by a circuit.

The terminal device 20 includes a communication unit 200, an analysis unit 201, a control content determination unit 202, a control unit 203, an input unit 204, a storage unit 205, a sleep diary management unit 206, a sound source unit 207, a D / A conversion unit 208, and a speaker 209. A liquid crystal driving circuit 210 and a liquid crystal display panel 211.
The communication unit 200 is a transmitter / receiver capable of transmitting / receiving information using a known wireless communication technique, and receives biological information transmitted from the communication unit 132 of the base body unit 13 constituting the swing rack 10. The function and information indicating the control content determined by the control content determination unit 202 (swing pace information, musical tone data) are acquired from the control content determination unit 202 and transmitted to the communication unit 132.

  Based on the biological information obtained from the swing rack 10 via the communication unit 200, the analysis unit 201 uses a biological cycle based on at least one of the biological cycle of heartbeat, breathing, and body movement obtained from the biological information. Analyze user status. As a function for analyzing a user's condition, for example, a function (RRI analysis function) for analysis using RRI (RR-Interval) analysis, a sleep depth estimation function (sleep depth estimation function), a user There is a function to analyze feelings (feeling analysis function). The analysis unit 201 may use all the functions of the RRI analysis function, the sleep depth estimation function, and the feeling analysis function, or may use at least one of the functions.

When using the RRI analysis function, the analysis unit 201 measures a heartbeat interval from data representing a heartbeat included in the biological information, and acquires heartbeat fluctuation time series data (RRI).
When the sleep depth estimation function is used, the analysis unit 201 estimates a user's sleep state based on information representing a state such as body movement or respiration included in the biological information. Examples of sleep states include “wakefulness”, “REM sleep”, and “non-REM sleep”. The analysis unit 201 identifies which of these types the sleep state of the subject person E corresponds. The sleep state in the analysis unit 201 can be estimated by a conventionally known method.

  The analysis unit 201 determines which level the sleep depth is based on the biological information, and outputs the determination result to the control content determination unit 202. The sleep depth is information representing the depth of sleep. For example, the sleep depth is “0” when the sleep state is “wake”, the sleep depth is “1” when the sleep state is “REM sleep”, and the sleep depth when the sleep state is “NREM REM sleep”. Is either “2”, “3”, or “4” depending on its depth. Whether the sleep depth is “2”, “3”, or “4” can be determined according to the state of heartbeat, respiration, body movement, etc. included in the biological information. This sleep depth indicates that the greater the numerical value, the deeper the sleep depth.

  When the feeling analysis function is used, the analysis unit 201 estimates what kind of feeling (psychology) based on at least one of heartbeat, breathing, and body movement represented by the biological information. For example, as a feeling, it is estimated which of a plurality of patterns such as “Niko Niko”, “Nemu”, “Easy”, “Good”, etc. When estimating the feeling pattern, the analysis unit 201 estimates the sleep state, the sleep depth is “wakefulness”, and the result of the RRI analysis is within the range of the normal heartbeat interval at the time of awakening It is determined that the user's feeling is “smile”. As to whether or not it is within the range of the normal heart rate interval, a reference value representing the normal range (for example, the heart rate is n1 to n2 times within a predetermined time) is stored in the analysis unit 201 in advance. Then, these reference values are compared with the results of the RRI analysis, and if they are within this range, it may be determined that they are normal. This “nicotine” represents, for example, a feeling when the user is awake and is assumed not to feel sleepy.

  The analysis unit 201 estimates the sleep state, and when the sleep depth is “wakefulness” and the result of the RRI analysis is longer or shorter than the normal heartbeat interval at the time of awakening, heartbeat fluctuation occurs. It is determined that the user's feeling is “nemui”. For example, a reference value representing a normal range is stored in advance, and when the upper limit value of this range is exceeded, it is determined that the heart rate interval is short, while when the lower limit value of this range is exceeded, the heart rate interval is Is determined to be long, and it is determined that the user's feeling is “need”. This “nemui” represents, for example, a feeling when the user is awakened but is estimated to feel sleepy.

The analysis unit 201 estimates the sleep state, and determines that the user's feeling is “easy” when the sleep depth is “non-REM sleep” (sleep depth 1). This “Susaya” represents a feeling when the user is in a sleep state and is estimated to be in a case where the sleep at the depth of sleep is shallow (non-REM sleep).
The analysis unit 201 estimates the sleep state, and determines that the user's feeling is “good” when the sleep depth is “REM sleep” (any one of sleep depths 1 to 4). This “good sound” represents a feeling when the user is in a sleep state and is estimated to be in a deep sleep state (REM sleep).

  The control content determination unit 202 determines the control content of the swing rack 10 based on the analysis result obtained from the analysis unit 201. The control content determination unit 202 not only uses the analysis result obtained from the analysis unit 201 but also the biometric information received by the communication unit 200 and the user according to the determined swing pace input from the input unit 204. Usage result information indicating whether or not E could be led to a relaxed state or a sleep state, instruction information input from the input unit 204, which is an instruction regarding swing pace, and an analysis result of the analysis unit 201 The control content can be determined using one of them.

  The control content determination unit 202 can guide the user to a relaxed state or a sleep state by shaking according to the determined swing pace, which is input from the input unit 204 based on the operation of the operator of the terminal device 20. A learning function for learning the relationship between the biological information and the swing pace in accordance with the use result information indicating the result of whether or not. By inputting the use result information, it is possible to evaluate the influence on the individual user E due to the swing based on the swing pace, and it is possible to determine the swing pace in consideration of the evaluation result.

  For example, there is utilization result information indicating that when the bed main body portion 12 is swung at a determined swing pace when certain biological information is obtained, the bed body portion 12 is promptly shifted to a relaxed state or has been able to fall asleep quickly. When input from the input unit 204, the relationship between the biological information and the swing pace at that time is stored in a table or the like in association with the evaluation value being increased, and similar biological information will be stored in the next and subsequent times. When obtained from the sensor 11, the table is referred to, and based on the relationship between the biological information, the swing pace, and the evaluation value, the biological information corresponding to the input biological information and having a higher evaluation value Is used as the swing pace of the biological information. On the other hand, when the use result information indicating that it is difficult to shift to the relaxed state or the sleep state when the bed main body 12 is swung at the determined swing pace is input from the input unit 204, the evaluation is performed. By updating so as to decrease the value, the frequency of use of the correspondence relationship between the biological information and the swing pace when it is difficult to shift to the relaxed state or the sleep state can be decreased.

  For this reason, it is possible to determine an appropriate swing pace according to the preference and characteristics of each user E, and it is possible for the user E to easily lead to a relaxed state or to fall asleep. Furthermore, since the evaluation is performed when the bed main body 12 is swung based on the determined swing pace, the accuracy of the evaluation is improved as the number of times the rack swing system 1 is used increases. In this way, since the terminal device 20 can be made to learn the influence of the swinging of the bed main body 12 on the user's E rack state or sleep state, the number of times the rack swing system 1 is used is reduced. As the number increases, the user E can be easily led to a relaxed state or can easily fall asleep.

The swing pace determination unit 2020 of the control content determination unit 202 determines the swing pace as the control content, and generates swing pace information representing the determined swing pace. The swing pace information is information representing a swinging pace when the bed main body 12 is driven to swing by the driving unit 133. The oscillating pace is a pace that oscillates at a cycle corresponding to a biological cycle based on at least one of heartbeat, respiration, and body motion obtained from biological information. That is, according to the biological cycle based on at least one of heartbeat, respiration, and body movement, the position of the bed main body 12 with respect to the base main body 13 is one end side (for example, the right end side) and the other with respect to the center position. The period when reciprocating between the end side (for example, the left end side) is determined as the swinging pace.
The swing pace may be determined so that the user E can easily relax or fall asleep. For example, the swing pace is longer than the cycle of a biological cycle (for example, breathing, heartbeat, etc.) (a predetermined number of biological cycles). The swing pace may be determined so that the bed main body portion 12 is swung at a double cycle). Compared with the case where the bed main body 12 is swung at a cycle shorter than the biological cycle, it is easier for the user E to relax or fall asleep when the bed main body 12 is swung at a cycle longer than the biological cycle. There is a case.

  In addition, the swing pace determination unit 2020 may determine the swing pace so as to swing at a timing different from breathing, heartbeat, and body movement represented by the biological information. When the bed main body 12 is swung, the sensor 11 may detect vibration generated by the rocking of the bed main body 12. Then, there is a possibility that data obtained from the sensor 11 as biometric information is detected as biometric information in which vibration caused by swinging is included. For this reason, by determining the swing pace so that the pace swings at a timing different from that of breathing and heartbeat, the biological information obtained from breathing, heartbeat, and body movement can be obtained by swinging the bed main body 12. It can reduce that the signal component according to the vibration which arises interferes, and can suppress the fall of the detection accuracy of biological information.

Further, the swing pace determination unit 2020 subtracts the vibration component corresponding to the drive signal of the motor that swings the bed body 12 from the information obtained as the biological information, thereby removing the biological information that excludes the vibration component due to the swing. The swing pace may be determined after obtaining the above. The processing of subtracting the vibration component corresponding to the drive signal of the motor that swings the bed main body 12 from the biological information may be performed by the analysis unit 201.
In addition, the swing pace determination unit 2020 may prohibit swinging in a cycle included in each assumed cycle range such as breathing, heartbeat, and body motion when determining the swing pace. That is, the bed main body 12 may be prohibited from swinging at the timing when the vibration component due to breathing, heartbeat, body movement, and the like and the vibration component of the vibration generated by the bed main body 12 swing are superimposed. .

  Further, the swing pace determination unit 2020 can determine the swing pace based on the biological information itself, but can also determine the swing pace based on the analysis result of the analysis unit 201. For example, when the analysis result of the RRI analysis function is used, the swing pace determination unit 2020 determines the swing pace so as to be a pace corresponding to the heartbeat interval obtained by the RRI analysis function. Thereby, the bed main-body part 12 can be rock | fluctuated at the pace according to the user's E heartbeat interval. For example, usage result information indicating that the user E is easy to relax or can quickly lead to a sleep state after swinging at a swing pace determined according to the heartbeat interval obtained by the RRI analysis function. If it is input, it is considered that it is effective for the user E to swing at a pace corresponding to the heartbeat interval, and the frequency of using the RRI analysis function is increased when determining the subsequent swing pace. Can (learning function).

  When the analysis result of the sleep depth estimation function is used, the swing pace determination unit 2020 determines the swing pace so as to be a pace corresponding to the sleep depth obtained by the sleep depth estimation function. Thereby, the bed main-body part 12 can be rock | fluctuated at the pace according to the sleep state. For example, when the bed main body part 12 is swung by a swing pace corresponding to the case where the sleep state is “wakefulness” and the sleep state shifts to “REM sleep”, the cycle is slower than the swing pace in “wakefulness” When the bed main body part 12 is swung at a swing pace that is the same, and the sleep state shifts to “non-REM sleep”, the bed main body part 12 at a swing pace that is slower than the swing pace in “REM sleep”. May be swung, and the rocking may be stopped after a predetermined time has elapsed. After swinging at a swing pace determined according to the sleep depth obtained by the sleep depth estimation function, use result information indicating that the user E is easy to relax or can quickly lead to the sleep state. If it is input, it is considered effective for the user E to swing at a pace corresponding to the sleep depth, and the frequency of using the sleep depth estimation function is increased when determining the subsequent swing pace. (Learning function).

  When using the analysis result of the feeling analysis function, the swing pace determination unit 2020 determines the swing pace so as to be a pace according to the feeling pattern estimated by the feeling analysis function. Thereby, the bed main-body part 12 can be rock | fluctuated at the pace according to the result from which the feeling of the user E was estimated. For example, when the bed main body 12 is swung by a swing pace according to the feeling pattern “Niko-Niko” and the sleep state shifts to “Nemu-i”, the cycle is slower than the swing pace in “Niko-Niko” When the bed main body 12 is swung at a swing pace, and the feeling pattern shifts to “slow”, the bed main body 12 is moved at a swing pace that is slower than the swing pace in “nemui”. When the feeling pattern shifts to “smoothly”, the bed main body 12 is swung at a swing pace that is slower than the swing pace in “Susaya”, and the swinging is stopped after a predetermined time. You may make it make it. After swinging at a swing pace determined according to the feeling pattern obtained by the feeling analysis function, usage result information indicating that the user E is easy to relax or can quickly lead to a sleep state. If it is input, it is considered that it is effective for the user E to swing at a pace corresponding to the feeling analysis function, so that the frequency of using the feeling analysis function is increased when determining the subsequent swing pace. (Learning function).

  The tone generation unit 2021 generates tone data corresponding to the biological information. Similar to the swing pace determination unit 2020 described above, the musical sound generation unit 2021 generates a type of musical sound to be generated based on the analysis result of at least one of the RRI analysis function, the sleep depth estimation function, and the feeling analysis function of the analysis unit 201. It is also possible to determine the tempo, volume, etc. of the musical sound. Here, it is only necessary to generate a musical sound that can lead to a state in which the user E can easily relax or fall asleep. For example, the musical sound content itself may be selected according to the state of the user E, or may be changed so as to have a frequency, tempo, or volume included in the musical sound. The tempo of the musical sound may be a tempo corresponding to the period of the biological information of the user E (for example, a tempo that is a predetermined number of times the biological period).

  The swing pace determination unit 2020 and the musical sound generation unit 2021 have been described with respect to the case where the control content is determined using the biological information received by the communication unit 200 (swing pace is determined or musical sound data is generated). The control content can be determined using at least one of utilization result information input from the unit 204, instruction information input from the input unit 204, and analysis result of the analysis unit 201.

  The control unit 203 performs control to output information related to the biological information obtained from the control content determination unit 202 by emitting sound or displaying the information on the screen. When outputting information related to biological information by sound, the control unit 203 outputs musical sound data representing information related to biological information to the sound source unit 207. When outputting information related to biological information as an image, the control unit 203 outputs image data to the liquid crystal driving circuit 210. Output to. Note that the musical sound data output from the sound source unit 207 is converted into an analog signal by the D / A conversion unit 208 (D / A converter) and emitted as sound by the speaker 209. The image data output from the liquid crystal driving circuit 210 is displayed as an image on the liquid crystal display panel 211.

  In addition, when sleep diary information is input from the sleep diary management unit 206, the control unit 203 performs control to output information related to the sleep diary information by emitting sound or displaying it on the screen. The control unit 203 controls each unit in the terminal device 20.

The acquisition unit 131 acquires the biological information output from the sensor 11 and converted from analog to digital by the A / D conversion unit 130, and supplies the biological information to the communication unit 132. The communication unit 132 transmits the biological information supplied from the A / D conversion unit 130 to the communication unit 200 of the terminal device 20 (step S102).

  On the other hand, when an application program for controlling the swing rack 10 is activated, the terminal device 20 determines whether or not an instruction to browse sleep diary information is input from the input unit 204 (step S201). ). When the instruction to browse the sleep diary information is not input (step S201—NO), the biological information transmitted from the communication unit 132 of the swing rack 10 is received (step S202). The analysis unit 201 analyzes the state of the user based on the biological information received by the communication unit 200 using at least one of the RRI analysis function, the sleep depth estimation function, and the feeling analysis function (step S203). The analysis result is output to the control content determination unit 202.

When the analysis result is obtained from the analysis unit 201, the control content determination unit 202 determines whether the user can be brought into a relaxed state or a sleep state by shaking according to the swing pace from the input unit 204, or It is determined whether or not an instruction regarding the swing pace has been input (step S204).

When the control content is determined, the communication unit 200 transmits information representing the determined control content to the communication unit 132 of the swing rack 10 (step S206).
Next, the control unit 203 outputs information based on the biological information by sound or an image (step S207).

  On the other hand, in step S204, as a result of whether or not the user has been able to guide the user to a relaxed state or a sleep state by shaking according to the swing pace, no instruction regarding the swing pace is input (step S204-NO). The control content determination unit 202 determines the control content based on the analysis result (step S208), and proceeds to step S206.

  On the other hand, when a request for browsing information of the sleep diary is input in step S201 (step S201-YES), the control unit 203 reads the sleep diary information from the storage unit 205 via the sleep diary management unit 206 ( In step S209), the sleep diary information is output by sound or image (step S210), and the process proceeds to step S201.

  Next, returning to the processing of the swing rack 10, the communication unit 132 receives information representing the control content from the communication unit 200 of the terminal device 20 (step S103). The control unit 134 drives each unit based on the received control content. For example, when there is swing pace information in the information representing the control content, a digital control signal for driving the drive unit 133 is generated in accordance with the swing pace information and output to the D / A conversion unit 135. The D / A conversion unit 135 converts the digital control signal output from the control unit 134 into an analog control signal and outputs the analog control signal to the drive unit 133. Thereby, the drive part 133 rocks the bed main-body part 12 with the period according to a control signal (step S104).
