The network 500 is not limited to these examples, and may be, for example, a public switched telephone network, Bluetooth (Bluetooth (registered trademark)), an optical line, an ADSL line, a satellite communication network, or the like.

Here, the outline of the sleep check system 100 according to the embodiment of the present invention will be described with reference to FIG. FIG. 3 is a schematic view showing an outline of a sleep check system 100 according to an embodiment of the present invention.

As shown in FIG. 3, as an example, the sleep check system 100 includes a sensor device 400 attached to a sleep check target person (hereinafter simply referred to as “target person”) such as an infant, when a plurality of infants sleep in the body. Detecting the direction, temperature, presence of breathing, etc. The detected data (sensing data) is transmitted to the terminal device 300. The terminal device 300 receives the sensing data, and 2. collecting sleep state information (posture information etc.) indicating the sleep state for each infant to be checked; Based on the collected sleep state information, the average number of times of turning over in a predetermined time, etc. is calculated for each target infant or for each of a plurality of grouped infant groups, and 4. Based on the calculated average number of times of turning, etc., it is determined whether or not there is a large amount of turning for each infant or group, and the like. Display information for displaying a sleep state, such as the orientation or body temperature of each infant or group to be checked and whether there is much temperature or turning over, is generated including the determined result.

As shown in FIG. When the generated display information is transmitted to the display unit 341 of the terminal device 300, 7. For each infant, (1) whether or not sleeping, (2) display of body direction (for example, text display such as "back", image display of up arrow), and (3) display of body temperature every predetermined time The screen is displayed collectively using a list (for example, every 5 minutes).

Here, "sleeping state" refers to the state of body orientation, body temperature, presence or absence of breathing, etc. at a certain point of time during sleeping of an infant. In addition, “sleeping state information” as used herein refers to these postural information indicating the direction of the body of the infant, temperature information indicating the body temperature of the infant, and respiration information indicating the presence or absence of respiration of the infant and the respiration rate. It is configured to include information indicating an attitude.

The sleep check system 100 can collectively receive check input of a target infant at predetermined time intervals on the screen display. For example, as shown in FIG. 3, a check button is provided to input that all target infants have been checked, with respect to the display showing the orientation of the body of each infant at 12:10 displayed on the display unit 341. If you press the check button and execute, the display showing the orientation of the body of all the targeted infants in the 12: 10 column is (1) of the check button as in the 12:00 and 12: 05 columns. The text display changes from "Checked" to "Done", (2) Arrows and border lines of face marks indicating rising are changed from solid lines to dotted lines, (3) Name of teacher who checked "Yuka Sensei" The text is displayed at the bottom of the column of the subject infant, (4) the column of the time of the checked object is changed to a uniform gray out display, or the display is changed so that it can be understood at a glance.

Conventionally, when a user such as a nursery teacher checks the sleep state of each kindergarten child for every predetermined time and records the check result by handwriting, if the predetermined time is 5 minutes, he takes charge of a certain time It takes 5 minutes just to complete the check of the sleep state of all the kindergarten children in the class and the recording of the check result by handwriting, and the check of the next round will start before completion or immediately after completion etc. There was a problem that the burden of the sleep check work was heavy. With respect to such a problem, with such a configuration of the sleep check system 100, the user can collectively input the check result based on the sleep state detected by the sensor device 400 without recording by handwriting. Since the display is changed, it is possible to know at a glance whether or not it has been checked, it is possible to reduce the burden of sleep check such as a mid-day sleep check of a nurse.

(Functional configuration)
FIG. 2 is a diagram showing an example of a functional configuration of the sleep check system 100 according to an embodiment of the present invention. As shown in FIG. 2, the sleep check system 100 includes an information processing device 200, a terminal device 300, and a sensor device 400.

Specifically, the sleep check system 100 is a sleep check system that checks sleep states of a plurality of subjects, and is attached to the subjects and detects the orientation of the subject's body every first predetermined period. Based on the detection unit 440 and posture information indicating the direction of the body of each subject detected by the detection unit 440 and generating posture information, and based on the posture information, the direction of the body for each subject is determined. The display unit 341 includes a display unit 341 to be displayed collectively and an operation input unit 351 to collectively receive an input of confirmation of a part or all of the subjects with respect to the displayed body orientation of each subject. When the input of confirmation of the operation input unit 351 is received, the display of the direction of the body of the subject who has been input for confirmation is changed.

Here, the “first predetermined period” refers to an interval time in which the posture detection unit 441 detects the orientation of the subject's body, and more specifically, in the case of detecting the orientation of the body every five minutes. The first predetermined period is "five minutes". In the setting of the first predetermined period, it may be set according to asphyxiation or SIDS measures whether or not to check the orientation of the subject's body (sleeping back or lying down) every few minutes in checking the sleep state .

With this configuration, the sleep check system 100 receives a plurality of inputs checked in a batch in checking the sleep state of the infant, and changes the display of the sleep state in which the input is received. The present invention can provide a sleep check system that can input the sleep check at once and can check at a glance whether or not the check has been completed.

The “posture data” mentioned here is data indicating the direction of the body of the subject infant detected by the detection unit 440. For example, the posture detection unit 441 detects the direction of the body using an acceleration sensor or a gyro sensor. In this case, it is referred to as data indicating the degree of inclination (angle) from the initial value at the start of detection. Further, the “posture information” mentioned here is information indicating the direction of the body by obtaining the direction of the body of the target infant (upturn, prone position, etc.) from the posture data.

(Information processing apparatus 200)
As shown in FIG. 2, the information processing apparatus 200 includes a control unit 210, a communication unit 220, and a storage unit 230.

The control unit 210 is a processor including a collection unit 211, a calculation unit 212, and a determination unit 213, and having a function of controlling each functional unit of the information processing apparatus 200. In addition, the control unit 210 may include the generation unit 214.

As an example, the control unit 210 refers to various information such as sleep state information stored in the storage unit 230 based on processing requests from the terminal device 300, the sensor device 400, or each functional unit of the information processing device 200. The update or deletion process may be performed, and output information for outputting the process result in the terminal device 300 may be generated. In this case, the generated output information is transmitted to the terminal device 300 via the communication unit 220 and the network 500.

Here, “output information” refers to display information and audio information output from the output unit 340 of the terminal device 300. Note that the information is not limited to the above information, and any information may be used as long as the sleeping state of an infant such as a kindergarten child can be output to a user such as a nurse, for example, including vibration information that uses the vibration function of the terminal device 300 , And may be output by vibration of the terminal device 300.

The collection unit 211 has a function of collecting data detected and output by the sensor device 400. The collection unit 211 collects posture data indicating the orientation of the body of each subject detected by the detection unit 440 of the sensor device 400, for example, and generates posture information. In the collection method of the collection unit 211, sensing data such as posture data received from the sensor device 400 is temporarily stored in the storage unit 230 for a predetermined period, and collected in response to an output request from the terminal device 300. Alternatively, sensing data may be collected in pseudo real time at the timing received from the sensor device 400. The collection unit 211 may store the collected various data and the generated various information (posture information, body temperature information, etc.) in the storage unit 230. The collection unit 211 may calculate the number of turns in the third predetermined period based on the stored posture information, and may store the calculation result in the posture information. In the calculation of the number of turning over in the collecting unit 211, for example, the number of times may be calculated by counting up (incrementing) when changing to the posture state of each body facing up, sideways or prone. A predetermined angle reference or angle range may be provided, and the number may be calculated by counting up when the reference or the range is exceeded.

The collection unit 211 may also collect temperature data indicating the body temperature for each subject detected by the detection unit 440 of the sensor device 400, as an example, and generate body temperature information.

The “temperature data” mentioned here is data indicating the temperature of the body of the subject infant detected by the detection unit 440. For example, when the temperature detection unit 442 detects a temperature using a thermometer or a thermographer, It refers to the temperature measured from the far infrared radiation emitted from the part or body where the temperature detection unit 442 outside the body of the subject infant is in contact. Moreover, "body temperature information" is the information which shows the said body temperature or flat heat by calculating | requiring the body temperature and flat heat of a certain point in time of the target infants from temperature data.

The calculation unit 212 has a function of calculating an average value or the like of a certain period based on the data stored in the storage unit 230. Specifically, the calculation unit 212 calculates, for example, the average number of turns in the third predetermined period for each subject based on the posture data stored in the storage unit 230. The calculation unit 212 may store the calculated average number in the storage unit 230.

Here, the “third predetermined period” is a period in which the number of turning over is checked at the time of sleep for each subject, and whether it is a sleep state or an awake state is checked. When the nursery check the mid-day sleep, the nap time (for example, 1 hour, 2 hours) may be set as the third predetermined period. In addition, average rem sleep and non rem sleep time of infants divided period (for example, 1 set of rem sleep and non rem sleep every age, late fetal period-newborn period: 40-50 minutes, 3-4 years old Period: 40 to 60 minutes, adult: 90 to 100 minutes) may be set as the third period.

In addition, the calculation unit 212 may calculate the average body temperature in the fifth predetermined period based on the temperature data stored in the storage unit 230 for each subject.

Here, the “fifth predetermined period” is a period in which the body temperature of each subject is checked. For example, when a childcare worker checks infants enrolled in a nursery or the like, the time from entry to exit Alternatively, a nap time (for example, 1 hour, 2 hours) may be set as the fifth predetermined period. Also, a period divided into average rem sleep and non rem sleep time of the infant may be set as the fifth predetermined period.

The determination unit 213 has a function of making a determination based on the information stored in the storage unit 230. More specifically, for example, the determination unit 213 compares, for each subject, the number of turns indicated by the posture information stored in the storage unit 230 with the average number of turns calculated by the calculation unit 212, It is determined whether or not there is much turning over in three predetermined periods.

Here, the “second predetermined period” refers to a period during which various data of the target person is stored in the storage unit 230. For example, in the case of sleep check of infants enrolled in a nursery school etc. The enrollment period may be up to six years, or may be half a year, one year, five years, or ten years according to the operation environment of the sleep check system such as the storage capacity of the storage unit 230 as another example.

The determination unit 213 may determine whether the subject is in the sleep state or in the awake state from the change in the direction of the body (body movement) in the third predetermined period. Here, an example of a method of determining whether the subject is in the sleep state or the awake state from the change in the direction of the body in the third predetermined period in the determination unit 213 will be described using FIG. 7. FIG. 7 is a graph in which the vertical axis represents the amount of change in the direction of the body (angle [°] from the reference position), and the horizontal axis represents the time axis (in seconds). The said graph is the graph which plotted over time about the variation data of the angle from the reference position for every sensor apparatus 400 (S1, S2, ... S10) attached to the object person.

Specifically, the determination unit 213 is a third predetermined value for each sensor device 400 plotted in the graph shown in FIG. 7 with respect to the temporal change of the inclination of the body detected by the detection unit 440 of the sensor device 400. The determination may be made using the following methods (1) to (3) based on the angle data group from the set reference position included in the posture data stored for a period.

(1) As an example, the determination unit 213 extracts the feature value of the body orientation of the posture data in each of the sleep state and the awake state in the posture data stored in the storage unit 230, and obtains the state determination model in advance. It is also possible to construct and use the constructed state determination model to determine whether the subject is in the sleep state or in the awake state based on the feature quantity of the body direction in the third predetermined period. Specifically, for example, the determination unit 213 extracts each feature amount using the angle data group included in the posture data as an explanatory variable, and the sleep and awakening states as an objective variable, and combines the feature amounts to obtain learning data. Do. The determination unit 213 constructs a state determination model by learning using machine learning (for example, a learning technique such as SVM (Support Vector Machine)) using the learning data. The determination unit 213 stores the constructed state determination model in the storage unit 230. The determination unit 213 performs pattern recognition using the stored state determination model based on the feature amount of the body orientation of the posture data collected in the third predetermined period, and determines whether it is a sleep state or an awake state. It may be determined (classified) if there is any. With such a configuration, if the orientation of the subject's body is detected, it is possible to accurately predict whether the subject is a sleep state or an awake state, and a user such as a childcare person sleeps on the subject's infants. You can reduce the burden of the sleep check by eliminating the need to check if you are awake or not.

(2) As another example, in the graph shown in FIG. 7, the determination unit 213 counts the number of times of passing of the graph to the reference angle or angle area in the target period, and the counted number of times of passing is predetermined. In the case of more than the number of times, it may be determined that the awake state. Alternatively, if the counted number of passes is smaller than a predetermined number, it may be determined that the patient is in the sleep state.

(3) In addition to the above (1) and (2), the determination unit 213 performs curve fitting (curve fitting) on the graph shown in FIG. 7 using interpolation, regression analysis, etc. A determination method may be used in which a curve that minimizes the distance of d is determined and the determination is made to determine (classify) whether it is a sleep state or an awake state based on the determined curve.

The determination unit 213 compares, for each subject, the average body temperature calculated by the calculation unit 212 with the body temperature indicated by the generated body temperature information, and determines whether or not the body temperature is normal during the third predetermined period. You may

The determination unit 213 determines whether the subject is in the sleep state or the awake state from the change in the direction of the body in the sixth predetermined period, and determines that the subject has transitioned from the awake state to the sleep state. Assuming that the user has started sleeping, the start processing request may be made to start posture detection and temperature detection of the detection unit 440 of the sensor device 400 under predetermined conditions.

For example, in the state (the awake state) before the target person starts to go to sleep, the determination unit 213 is in a state in which the posture detection and temperature detection of the detection unit 440 of the sensor device 400 are partially stopped The state of the posture detection in the case, the detection stop of the temperature detection, the sleep state, etc.), the determination unit 213 determines that the subject has begun to sleep, and determines the transition to the sleep state for the first time, the body for every first predetermined period. The start processing request is transmitted to the detection unit 440 of the sensor device 400 to start a full-fledged sleep check, such as detecting the direction of the subject, and the detection unit 440 of the sensor device 400 transmits the start processing request for the first time. Detection may be initiated to initiate a regular sleep check. With such a configuration, unnecessary detection of the awakening state can be omitted, and the body direction of the subject can be efficiently detected from both the viewpoint of processing performance and the viewpoint of communication capacity and storage capacity. it can.

The determination unit 213 groups the target persons, and in the grouped target persons, at least one of the number of persons determined to have a large number of turns or the number of persons determined that the body temperature is not normal is larger than a predetermined number It may be determined whether or not. Specifically, for example, in the case of a nursery check at nursery school, the determination unit 213 groups children in a class in which children are enrolled, and in the grouped children, the number of children who turn over frequently or children whose temperature is higher than usual. It may be determined whether any one of the number of people is greater than a predetermined number. Here, the “predetermined number of people” may be a half of the number of people to be grouped, or may be two thirds, or may be set according to a sleep check check system or the like.

In addition to the above, the determination unit 213 may determine whether or not the subject is different from usual sleep, for example, (1) a rate of increase in body temperature is compared with a predetermined rate of increase. It may be determined whether it is abnormally high (the possibility of being overheated is high), or (2) it may be determined whether the number of wake ups and sleeps is greater than a predetermined number (3) Machine learning may be used to extract the feature quantity of the direction of the sleeping state in which the patient lies in the prone position and predicts and determines the prone state.

The generation unit 214 generates output information (display information, audio information) to be output by the terminal device 300 based on various information stored in the storage unit 230. Specifically, the generation unit 214 generates display information to be displayed on the display unit 341 as illustrated in FIGS. 3 and 4 based on, for example, posture information, temperature information, personal information, and the like for each target infant. You may The generation unit 214 transmits the generated output information to the output unit 340 of the terminal device 300 via the communication unit 220 and the network 500.

The communication unit 220 has a function of executing communication with the terminal device 300, the sensor device 400, or another information processing device 200 via the network 500 under the control of the control unit 210. The communication may be wired or wireless, and any communication protocol may be used as long as mutual communication can be performed. Specifically, the communication unit 220 may transmit output information to the terminal device 300 or may receive sensing data from the sensor device 400.

It may be generated in a general data format that can be displayed on the screen by the terminal device 300, such as image data.

Under control of the control unit 310, the display unit 341 collectively displays the orientation of the body for each subject based on the posture information stored in the storage unit 330. Further, when the display unit 341 receives an input of confirmation of the operation input unit 351 under the control of the control unit 310, the display unit 341 collectively changes the display of the body direction of the subject subjected to the confirmation input.

With such a configuration, the display unit 341 can confirm at a glance the orientations and temperatures of the bodies of the displayed plurality of target infants, and it can also be checked at a glance how much sleep has been checked. Thus, it is possible to provide a sleep check system capable of reducing the load on the user such as a nurse who must check the sleep of a plurality of subjects at one time in the morning sleep check etc.

In addition, when the display unit 341 receives an input of confirmation of the operation input unit 351 under the control of the control unit 310, if there is only one target person who remains in the predetermined direction of the body, the target person who has received the confirmation input The alert display may be displayed without changing the display of the body orientation. Specifically, when there is even one target person whose infant's body is in the prone position in the afternoon sleep check of the nursery school, if the confirmation input is accepted and the display is changed, it will be erroneously checked, There is a concern that check omission will occur. For such a concern, the display unit 341 sets the predetermined body orientation as “face-down”, and when there is even one child whose body orientation is face-down, the body of the subject who has been confirmed and entered It is also possible to display an alert display with a message such as “There is a sleeping child lying down” without changing the display of the orientation all at once.

Further, as an example, the display unit 341 may select and display the orientation of the display target body of the subject for each age of the subject or for each age and age under the control of the control unit 310. When children in different ages and ages are in one class in the nocturnal check at the nursery school, the check paper format is limited, although it is acceptable to check every 10 minutes for 1-year-old and older children, same as 0-year-old children 5 There are cases where you have to check every minute. The operation of the sleep check differs depending on the nursery school, but there are also cases where there is no problem with children aged 2 and over every 10 minutes.

The display unit 341 displays, for example, the orientation of the display target object for each age, age (for example, 0 years, 1 year, 2 years, etc.) of the target kindergarten children every 5 minutes if the age is 0 years. By targeting the direction of the body and setting the direction of the body every 10 minutes if it is 1 year old, it is possible to display only the display portion of the appropriate check object, which can reduce the burden on the user who checks . In addition, since selection can be performed on the display side without changing the detection interval set by the sensor device 400, it is possible to provide a sleep check system excellent in versatility.

Furthermore, as an example, under the control of the control unit 310, the display unit 341 selects and displays the orientation of the display subject's body based on the entry period of the subject stored in the storage unit 330. it can. For example, when the sleep check system 100 is used for a midday sleep check in a nursery school, children who have not entered a nursery school will not sleep stably, so they will check their sleep frequently (for example, every 5 minutes) regardless of age or age. There are times when it is better to do. With regard to the selection of the check interval at the age and age of the children (selection of the orientation of the body to be displayed), it is possible to select the check interval more in accordance with the actual situation.

As an example, the display unit 341 may change the display of the orientation of the body of the subject who has been determined to be frequently turned over by the determination unit of each device under the control of the control unit 310. Specifically, for example, the display unit 341 highlights in the arrow display that is the display of the direction of the body of the subject determined to be frequently turned by the control of the control unit 310 (for example, “turning is abnormally high. Add a text display such as “is”, change the color with other arrows, make the border of the arrow thicker, blink it, change its size, etc.). With such a configuration, it is possible to notify a user such as a nurse who checks the sleep that the appearance is different from usual sleep, and makes the target kindergarten child notice that there is a high possibility of being sleepy be able to. A user such as a nursery teacher can confirm the highlighted display and arrange the sleeping environment of the target kindergarten child (for example, change the futon and blanket etc.) and take preventive measures such as SIDS including lying down be able to.

As an example, the display unit 341 may change the display of the orientation of the body of the subject whose temperature is determined not to be normal by the determination unit of each device under the control of the control unit 310. Specifically, for example, the display unit 341 highlights (for example, “body temperature”) in the temperature display (such as 37.0 °) of the subject whose temperature is determined not to be normal by the control of the control unit 310. There is an unusually large amount of text display, such as adding text display, changing color with other numerical displays, making characters bold, displaying blinking, changing size of characters, etc.). With such a configuration, it is possible to determine that the target infants are likely to be too warm (and, consequently, have a high possibility of developing SIDS), and preventive measures such as SIDS including prone lying You can If the subject is an infant, if the temperature rises above the child's own temperature due to excessive room temperature or excessive clothing during sleep, the autonomic nerve gives priority to thermoregulation and moves the respiration and heart freely. Research has shown that As there are studies that many cases of SIDS have had high fever due to poor health and stressful high fever due to entering a nursery school for the first time, it is important whether the subject's infants were able to dissipate heat properly. It is effective from the viewpoint as well, to notify the user such as a childcare person that the body temperature has risen by lying down.

The display unit 341 is, for example, at least any one of the number of people who are determined to have many turns or the number of people who are determined not to be normal in the target person grouped by the determination unit of each device under the control of the control unit 310. If it is determined that the number of people is greater than the predetermined number of people as a result of determining whether the number of people is greater than the predetermined number of people, an alert display prompting the user to change the setting of the sleep environment for collective display of the grouped persons You may display it. For example, when there are a large number of persons who determined that the body temperature is not normal as compared with the predetermined number of people, the display unit 341 says, "There are many children whose body temperature is abnormally high. The alert display may be displayed in a pop-up to indicate a text display such as “Please change the setting of”. With such a configuration, it is possible to notify that a large number of children sleeping in the same environment appear to be different from ordinary sleep, and the overall sleep environment is not appropriate for a user such as a nurse It is possible to realize that the possibility is high. A user such as a nursery teacher can confirm the alert display and arrange the entire sleep environment of the target children (for example, change the setting of heating and cooling, open a window, etc.), efficiently, sleep We can help prepare the environment.
