[About the main unit 10]
Next, the details of the main unit 10 constituting the awakening device D will be described with reference to FIGS. FIG. 5 is a perspective view of the main unit 10 with the main unit 10 removed from the chair S, and FIG. 6 is an exploded perspective view of the main unit 10. FIG. 7 is a top view of the main unit 10, and FIG. 8 is a top view of the main unit 10 in a state where the ECU 12 is removed from the main unit 10. 9 is a sectional view taken along line IX-IX of FIG. 7, and FIG. 10 is a side view of the main unit 10.

  As shown in FIGS. 5 and 6, the main unit 10 mainly includes an ECU 12 (electronic control unit), a vibration motor 13, and a holding member 11 that holds the ECU 12 and the vibration motor 13 housed therein.

  The holding member 11 includes a cover main body 11A, an ECU mounting portion 11B, a holding member mounting portion 11C, and a vibration motor mounting portion 11D. The holding member 11 is formed of, for example, a resin material.

  The cover main body 11A has a substantially U-shaped vertical cross section that is open at the top, and functions as a housing for the awakening device D. In addition, a concave portion 17 that is depressed inward is provided on the lower surface of the cover body 11A. A battery end plate 20 is attached to the side wall of the concave portion 17, and a dry battery 23 is housed in the concave portion 17 with electrodes arranged in a direction facing the battery end plate 20. The dry battery 23 functions as a power source for the ECU 12 and the vibration motor 13. The battery cover 21 is a member that engages with the opening on the lower side of the recess 17 and covers the dry battery 23 housed in the recess 17. In addition, since the battery 23 can be exposed by removing the battery cover 21, the battery 23 can be easily replaced.

  An ECU mounting portion 11B (first mounting portion 11Ba and second mounting portion 11Bb) and an ECU supporting portion 19 are formed on the surface of the concave portion 17 on the side of the seat portion S1 so as to protrude toward the seat portion S1. . The ECU mounting portion 11B and the ECU supporting portion 19 are members formed integrally with the cover main body 11A and supporting the ECU 12. A screw hole for screwing with the fixing screw 18 is formed in the center of the ECU mounting portion 11B. Ribs are formed around the ECU attachment portion 11B and the ECU support portion 19, respectively, thereby increasing the strength of the ECU attachment portion 11B and the ECU support portion 19.

  As shown in FIG. 6, a screw insertion hole 12B is formed on one diagonal of the four corners of the board of the ECU 12, and a support part insertion hole 12C is formed on the other diagonal. The screw insertion hole 12B of the ECU 12 and the ECU mounting portion 11B are opposed to each other, and the supporting portion insertion hole 12C and the ECU support portion 19 are arranged so as to face each other. By screwing the fixing screw 18 into the screw hole, the ECU 12 can be attached to the holding member 11.

  Here, the ECU 12 and the recess 17 are separated from each other. By providing a space between the ECU 12 and the recess 17 in this way, the heat radiation of the ECU 12 can be improved.

  As shown in FIG. 8, a through hole 17A is formed at the center of the upper surface of the concave portion 17 to release heat exhausted from the ECU 12, so that heat dissipation can be further improved. it can. Further, through the through hole 17A, the inside of the main unit 10 or the attached state of the dry battery 23 can be confirmed.

  The cover main body 11A is formed with a plurality of ribs 22 connecting the inner surface of the cover main body 11A and the concave portion 17, and the ribs 22 can improve the rigidity of the cover main body 11A.

  The holding member attaching portion 11C is a portion for attaching the main unit 10 to the seat portion S1, and is formed as a flange extending to both sides of the cover main body 11A. A plurality of through holes 15 are formed in the holding member mounting portion 11C, and tapping screws are passed through the respective through holes 15 to fix the holding member mounting portion 11C to the lower surface of the seat portion S1. Thereby, the main unit 10 is attached to the lower side of the seat S1.

  The vibration motor mounting portion 11D has a housing groove in which the vibration motor 13 is mounted and in which the vibration motor 13 is housed. The vibration motor 13 corresponds to a vibration device according to the present invention, and is switched between driving and stopping based on a control signal received from the ECU 12. For example, an unbalanced mass type motor may be used as the vibration motor 13.

  As shown in FIG. 9, the vibration motor 13 is housed in the housing groove, and the vibration motor cover member 14 is disposed on the upper portion. The vibration motor cover member 14 covers the upper surface of the vibration motor 13. Further, since the upper and lower portions of the vibration motor 13 are sandwiched between the vibration motor mounting portion 11D and the vibration motor cover member 14, the displacement of the vibration motor 13 can be suppressed even in the driving state.

  As shown in FIG. 10, the upper end of the vibration motor cover member 14, that is, the end on the seat S <b> 1 side is located closer to the seat S <b> 1 than the ECU 12. Accordingly, even when an impact is received from the seat S1 side or the lower surface side of the holding member 11, the vibration motor cover member 14 comes into contact with the resin plate 40 constituting the lower surface of the seat S1 before the ECU 12. Since the contact is easy, the ECU 12 can be suitably protected without providing a protection member above the ECU 12. As described above, since it is not necessary to provide a protection member above the ECU 12, the number of components of the main unit 10 can be reduced.

  The ECU 12 is a control device that controls the awakening device D. In the present embodiment, the ECU 12 controls the vibration motor 13 based on a potential difference signal converted into a digital signal indicating a respiratory interval detected by the biological sensor 30. It has a function to control driving. The ECU 12 has a wireless communication unit 12A for performing wireless communication, as well as a CPU, a ROM, and a RAM for operation control. The wireless communication unit 12A enables two-way communication with the wireless communication terminal 2. Then, the ECU 12 may control the operation of the vibration motor 13 based on a control signal (a drive signal, a stop signal, and the like) received from the wireless communication terminal 2.

  Specifically, the signal input to the ECU 12 is a potential difference signal converted into a digital signal by the signal processing circuit, and the output is power for driving the vibration motor 13. The RAM temporarily stores parameters including signals under arithmetic control and input / output signals, and functions as a storage unit that stores a potential difference signal converted into a digital signal and other signals.

  The ROM stores a program executed by the CPU and predetermined parameters. The program includes, for example, a setting program for setting a predetermined reference value, and a determination program for determining an awake state based on the reference value. A program and a driving program for driving the vibration motor 13 are included.

  Here, the ECU 12 has a function of driving the vibration motor 13 by supplying electric power in accordance with an instruction from the CPU. The instruction signal of the CPU is generated by calculating a signal from the biological sensor 30 (respiration sensor). That is, the CPU determines the awake state of the occupant based on the signal transmitted from the biological sensor 30, and drives the vibration motor 13 when determining the low awake state (ie, not the awake state). A signal is output to the vibration motor 13. Thereby, when the seated person is in the low awake state, it is easy to recover to the awake state or maintain the awake state by applying the vibration stimulus.

  Further, as shown in FIG. 10, a plurality of ribs 16 are formed on the outer surface of the cover main body 11A to connect the cover main body 11A and the holding member mounting portion 11C. Thereby, the rigidity of the holding member 11 can be increased. Further, as shown in FIG. 10, a plane extending at least one surface of the rib 16 overlaps the vibration motor 13. In other words, in the side view of the main unit 10, at least one rib 16 is present at a position overlapping the vibration motor 13 in the front-rear direction, and thus the vibration from the vibration motor 13 can be attached to the holding member. Through the portion 11C, it can be efficiently transmitted to the seat portion S1.

[Functions of Awakening Device D]
First, details of the functions provided in the awakening device D will be described.

  The data storage unit 100 is mainly realized by the memory 12m of the ECU 12. The data storage unit 100 includes detection data (respiration data, etc.) obtained by the biological sensor 30, data for determining the awake state of the occupant (data of prior probability, etc.), a flag value indicating ON / OFF of the awakening support function, and a timer. Various data such as setting information (driving start time and the like) is stored.

  The body signal detection unit 110 is mainly realized by the biological sensor 30, the CPU 12p, and the memory 12m. For example, the biological sensor 30 is a pressure sensor, and detects an electric resistance that changes according to the breathing of the occupant. Then, the body signal detection unit 110 calculates the pressure based on the electric signal related to the electric resistance value detected by the biological sensor 30 (pressure sensor), and obtains respiration data based on the calculated pressure. The body signal detection unit 110 may use waveform data (respiration waveform data) indicating a temporal change in pressure with the calculated pressure as the vertical axis and time as the horizontal axis, as the respiration data.

  The communication unit 120 is mainly realized by the wireless communication unit 12A, and performs bidirectional communication with the wireless communication terminal 2. For example, the communication unit 120 transmits respiration data (respiration waveform data) detected by the body signal detection unit 110 to the wireless communication terminal 2. In addition, the communication unit 120 transmits a determination result by the awake state determination unit 140 described later to the wireless communication terminal 2.

  Further, for example, the communication unit 120 receives time information from the wireless communication terminal 2 and synchronizes the time with the wireless communication terminal 2 based on the received time information. The communication unit 120 receives the timer setting information from the wireless communication terminal 2, and controls the operation of the vibration motor 13 based on the received timer setting information. In addition, the communication unit 120 receives various control signals such as a switch signal for switching ON / OFF of the awakening support function, a drive signal for driving the vibration motor 13, a stop signal for stopping the vibration motor 13, from the wireless communication terminal 2, The operation of the vibration motor 13 is controlled based on the received control signal.

  The parameter setting unit 130 is mainly realized by the CPU 12p and the memory 12m. The parameter setting unit 130 determines a parameter (pre-advance) used by the awake state determination unit 140 to determine the awake state based on the time (the acquisition time of the body signal) set according to the time information received from the wireless communication terminal 2 by the communication unit 120. Probability). Hereinafter, a specific example will be described.

  FIG. 13 shows an example of the relationship between circadian rhythm (circadian rhythm) and prior probability. The horizontal axis in FIG. 13 indicates time, and the vertical axis indicates the value of the prior probability. Further, P (H1) in FIG. 13 corresponds to the prior probability of the low awake state, and P (H2) corresponds to the prior probability of the awake state, and has a relationship of P (H1) + P (h2) = 1.

  As shown in FIG. 13, the values of P (H1) and P (H2) change according to the time, and the parameter setting unit 130 detects the respiration data detection time (or the current time). Are set as the prior probabilities of P (H1) and P (H2). Explaining with a specific example, in the time period from 7:00 to 14:00, the parameter setting unit 130 sets P (H1) = Pa2 and P (H2) = Pb2, and easily falls into a low arousal at 14:00. From 16:00 to 16:00, P (H1) = Pa1 (> Pa2) and P (H2) = Pb1 (<Pb2).

  The awake state determination unit 140 is mainly realized by the CPU 12p and the memory 12m. The awake state determination unit 140 determines the awake state (low awake state / awake state) of the seated person based on the respiration data (respiration waveform data) detected by the body signal detection unit 110. More specifically, the arousal state determination unit 140 determines a respiration interval (RI) indicating a respiration interval based on respiration data, an RrMSSD (Respiration root Mean Square Successive Difference) indicating variation in RI, and a unit time of respiration data. P_vel (Pressure velocity) indicating the degree of change of the occupant is determined based on the respective data, the value of the prior probability set by the parameter setting unit 130, and an algorithm using a Bayes filter. . A specific example of the process performed by the awake state determination unit 140 will be described later.

  The vibration motor control unit 150 is mainly realized by the ECU 12 and the vibration motor 13. When the communication unit 120 receives the drive signal of the vibration motor 13 from the wireless communication terminal 2, the vibration motor control unit 150 drives the vibration motor 13, and when the vibration motor 13 is being driven, the vibration motor 13 When the stop signal is received, the vibration motor 13 is stopped.

  Further, the vibration motor control unit 150 may drive the vibration motor 13 when the awake state determination unit 140 determines that the seated person is in the low awake state. The vibration motor control unit 150 stops driving the vibration motor 13 when the occupant leaves the chair S, that is, when the body signal detection unit 110 no longer detects the occupant's body signal. Good.

  Also, the vibration motor control unit 150 may drive the vibration motor 13 only when the awakening support function is set to ON. In addition, the processing may be executed for the body signal detection unit 110 and the arousal state determination unit 140 only when the awakening support function is set to ON.

[Functions of Wireless Communication Terminal 2]

  The communication unit 200 is mainly realized by the wireless communication unit 2C, and performs two-way communication with the awakening device D. The communication unit 200 includes a control signal transmission unit 201. The control signal transmission unit 201 controls the vibration motor 13 based on an operation received by an input reception unit 220 described later (a drive signal of the vibration motor 13, Signal, etc.) to the awakening device D that has received the selection by the selection receiving unit 230. In addition, the communication unit 200 transmits a switch signal of the awakening support function, setting information of a timer, and the like to the awakening device D whose selection has been received by the selection receiving unit 230, in addition to the above signal. Further, the communication unit 200 may transmit the time information of the wireless communication terminal 2 to the awakening device D at the start of wireless communication or at an arbitrary timing thereafter to synchronize the time.

  Further, for example, the communication unit 200 receives data such as respiration data (respiration waveform data) transmitted from the awakening device D and a determination result by the awakening state determination unit 140.

  The display control unit 210 is mainly realized by the control unit 2A, the storage unit 2B, and the display unit 2E. For example, the display control unit 210 displays, on the display unit 2E, a waveform based on the breathing data received from the awakening device D by the communication unit 200, a determination result of the occupant's awake state determined by the awake state determination unit 140, and the like. . Specifically, the display control unit 210 displays various screens such as an operation screen W1, a management list screen W2, and a timer setting screen W3 described later on the display unit 2E.

  The input receiving unit 220 is mainly realized by the control unit 2A, the storage unit 2B, and the input unit 2D. For example, the input receiving unit 220 receives an operation from the input unit 2D while various screens are displayed on the display unit 2E. Specifically, the input receiving unit 220 performs an operation of driving the vibration motor 13, an operation of stopping the driving of the vibration motor 13, an operation of turning on or off the awakening support function in the awakening device D, and a driving timer of the vibration motor 13. Various operations, such as an operation for setting the, are accepted.

  The selection receiving unit 230 is mainly realized by the control unit 2A, the storage unit 2B, and the input unit 2D. For example, the selection receiving unit 230 receives a selection of a chair S (awakening device D) to which information such as a control signal corresponding to the operation received by the input receiving unit 220 is to be transmitted. Specifically, the selection receiving unit 230 receives the selection of the chair S to be processed from the displayed chairs S while the screen displaying the chair S to be managed is displayed on the display unit 2E. .

[Process Executed in State Monitoring System 1]
Next, the flow of processing performed in the state monitoring system 1 will be specifically described with reference to FIGS.

[ON / OFF processing of awakening support function]
FIG. 14 shows a sequence diagram relating to processing for turning on / off the awakening support function of the awakening device D of the chair S, which is executed in the state monitoring system 1.

  As shown in FIG. 14, first, the wireless communication terminal 2 and the awakening device D provided in the chair S establish wireless communication (S101, S201), and the wireless communication terminal 2 transmits time information (current date and time). The information is transmitted to the awakening device D to synchronize the time information with each other (S102, S202). At the time of the first communication between the wireless communication terminal 2 and the awake device D, the pairing process may be executed.

  Next, the control unit 2A of the wireless communication terminal 2 causes the display unit 2E to display an operation screen W1 for operating the awakening device D that has started the communication (S103).

  FIG. 19 shows an example of the operation screen W1. As shown in FIG. 19, the operation screen W1 includes an ON button e1, an OFF button e2, a selection state display frame e3, a vibration start button e4, a vibration stop button e5, a respiration data display area e6, a determination result display area e7, A management list screen display button e8 is displayed.

  Here, the ON button e1 is an operation unit for setting the wake-up support function of the wake-up device D to ON, and the OFF button e2 is an operation unit for setting the wake-up support function of the wake-up device D to OFF. . The selection state display frame e3 is a frame image indicating the current setting of the awakening support function.

  The vibration start button e4 is an operation unit for vibrating the vibration motor 13 provided in the awakening device D. The vibration stop button e5 is an operation unit for stopping vibration of the vibration motor 13 provided in the awakening device D. Department.

  The respiration data display area e6 is a display area for displaying a waveform pattern of respiration data obtained for the occupant of the chair S received from the awakening device D. The determination result display area e7 is a display area for displaying the determination result of determining the awake state of the occupant of the chair S.

  The management list screen display button e8 is an operation unit for displaying on the display unit 2E a list screen (management list screen W2 described later) of the chair S (awake device D) managed by the wireless communication terminal 2.

  Here, when the control unit 2A of the wireless communication terminal 2 receives the input of the switch operation of the awakening support function by pressing the ON button e1 or the OFF button e2 of the operation screen W1 from the operator through the input unit 2D (S104), the input is performed. An ON or OFF switch signal set according to the pressed button is transmitted to the awakening device D via the wireless communication unit 2C (S105).

  When receiving the switch signal from the wireless communication terminal 2 via the wireless communication unit 12A (S203), the CPU 12p of the awakening device D switches ON / OFF of the awakening support function based on the received switch signal (S204). The above is an example of the processing for turning on / off the awakening support function.

[Sitant status display processing and vibration processing]
Next, an example of the state display processing and the vibration processing of the seated person will be described with reference to FIG. As a premise of the processing illustrated in FIG. 15, it is assumed that a person is sitting on the chair S after the wireless communication terminal 2 and the awakening device D start communication.

  As shown in FIG. 15, the CPU 12p of the awakening device D refers to the time (current time) (S211), and sets the prior probabilities of the low awake state and the awake state based on the referred time (S212). . Note that the process of S212 is executed by the parameter setting unit 130.

  Next, the CPU 12p of the awake device D determines the awake state of the occupant of the chair S based on the information detected by the biological sensor 30 (S213). Here, the awake state determination process performed in S213 will be described with reference to the flowchart shown in FIG.

[Awake state determination processing]
The awake state determination processing according to the present embodiment includes data on RI (Respiration Interval) indicating a breathing interval, RrMSSD (Respiration root Mean Square Successive Difference) indicating variation in RI, and P_vel (Pressure velocity) described later. This is a process of determining the awake state of the seated person based on the result of applying a Bayes filter to the above. Note that the term P_vel is used for convenience in the present embodiment for the degree of change per unit time of respiration data (also referred to as a pressure signal).

First, when the living body sensor 30 detects sitting on the chair S, respiratory data that fluctuates according to the depth of breathing of the occupant is acquired based on a change in electrical resistance.
The biological sensor 30 acquires the breathing data of the occupant as a breathing data acquiring step, and the CPU 12p records (acquires) the breathing data transmitted from the biological sensor 30 in the memory 12m as potential difference data (S11).

  Next, based on the acquired respiration data of the biological sensor 30, the CPU 12p shows the waveform data of the respiration sensor pressure, which is a transition of the pressure for a predetermined time, and the transition of RI, which is the interval of one respiration of a person, for a predetermined time. RI waveform data is generated (S12).

  Next, in the calculation step, the CPU 12p calculates an average value RIm of RI for each section, with a predetermined interval (for example, 30 seconds) as one section of the generated RI waveform data.

  Next, the CPU 12p compares the calculated RIm (t) of one section with RIm (t + 1) of the next section, and determines whether RIm (t + 1) is a value larger than the immediately preceding RIm (t). Is determined (S13).

ＲｒＭＳＳＤは、眠気を覚まそうとする際の交感神経の活性化に伴って覚醒低下状態の初期段階に大きくなる。そこで、このＲｒＭＳＳＤを覚醒判定の指標の一つとすることで、より正確な覚醒判定を実現するものである。 When determining that RIm (t + 1) is equal to or smaller than RIm (t) (S13: N), the CPU 12p determines that the seated person is in the awake state (S20).
On the other hand, when the CPU 12p determines that RIm (t + 1) is greater than RIm (t), in other words, when the value of RIm is higher in the later section than in the previous section (S13). : Y), the CPU 12p calculates RrMSSD in the calculation step (S14). Specifically, the CPU 12p calculates the RrMSSD for each section with a predetermined interval (for example, 30 seconds) as one section.
Here, RrMSSD is a value calculated by the following equation 1 when the t-th RI is defined as RI (t) and the n-th RI from the t-th is defined as RI (t + n). 9 shows variations in RI.

RrMSSD increases at an early stage of a low arousal state with activation of sympathetic nerves when trying to wake up drowsiness. Thus, by using this RrMSSD as one of the indices for awakening determination, more accurate awakening determination is realized.

  Next, the CPU 12p compares the calculated RrMSSD (t) of one section with RrMSSD (t + 1) of the next section, and determines whether RrMSSD (t + 1) is larger than the immediately preceding RrMSSD (t). Is determined (S15).

When determining that RrMSSD (t + 1) is equal to or smaller than RrMSSD (t) (S15: N), the CPU 12p determines that the occupant is in the awake state (S20).
On the other hand, when the CPU 12p determines that RrMSSD (t + 1) is larger than RrMSSD (t), in other words, when the value of RrMSSD is higher in the later section than in the previous section (S15). : Y), the CPU 12p calculates P_vel as an operation step (S16).

  Here, P_vel is the degree of change in breathing data per unit time (degree of change in breathing) as described above, in other words, the absolute value of the time-differentiated value of the breathing data obtained within a predetermined time. is there. In particular, P_vel is a value from which a median filter and a low-pass filter have been passed and noise has been removed. Note that P_vel is data for applying a Bayes filter described later.

  Next, in the calculation process, the CPU 12p calculates P_velmean, which is the average value of P_vel every 10 seconds, and determines a P_vel pattern based on P_velmean (S17).

The P_vel pattern is a pattern determined by the number of times P_velmean has decreased within a predetermined time, and is selected from a predetermined predetermined number of patterns.
In the present embodiment, the P_vel pattern is the number counted when P_velmean falls below the P_velmean of the previous 10 seconds between the time t of 30 seconds and the time t + 1 of 30 seconds after the time t. May be determined by a combination of

  Strictly speaking, the number for the first 10 seconds of time t is a comparison of P_velmean for the first 10 seconds of time t and P_velmean for 10 seconds before time t. The P_vel pattern is data for applying a Bayes filter described later.

このように、後述する各種データに係る覚醒状態に関わる確率を乗じた、Ｐ（Ｄ１｜Ｈ１）×Ｐ（Ｄ２｜Ｈ１）×Ｐ（Ｄ３｜Ｈ１）、及びＰ（Ｄ１｜Ｈ２）×Ｐ（Ｄ２｜Ｈ２）×Ｐ（Ｄ３｜Ｈ２）は、それぞれベイズフィルタの尤度に相当するものである。また、Ｐ（Ｈ１）及びＰ（Ｈ２）はそれぞれ、低覚醒状態、覚醒状態の事前確率に相当するものであり、両者の合計は１となる。次に、ベイズフィルタに用いられるデータに関する確率及び事前確率について詳細に説明する。 Next, the CPU 12p uses the Bayes filter that uses the values of the RIm, P_vel, and P_vel patterns calculated by the CPU 12p as data in the arousal determination step, and the seated person is in a low arousal state (a state in which drowsiness is occurring). It is determined whether a certain probability is greater than a probability that the occupant is in the awake state (S18).
Here, the Bayesian filter equation is expressed by Equation 2.

In this way, P (D1 | H1) * P (D2 | H1) * P (D3 | H1) and P (D1 | H2) * P ( D2 | H2) × P (D3 | H2) respectively correspond to the likelihood of the Bayes filter. Further, P (H1) and P (H2) correspond to the prior probabilities of the low awake state and the awake state, respectively, and the sum of both is 1. Next, the probabilities and prior probabilities regarding data used in the Bayes filter will be described in detail.

Here, P (D1 | H1) is a conditional probability that the data D1 is obtained when the occupant is in the low awake state with respect to the data D1 that is the value of RIm, and P (D1 | H2) is the seated state. Is the conditional probability that the data D1 is obtained when the person is awake.
P (D2 | H1) is a conditional probability that the data D2 is obtained when the occupant is in the low awake state with respect to the data D2 that is the value of P_velmean, and P (D2 | H2) is the wake of the occupant. This is the conditional probability that the data D2 is obtained when in the state.
P (D3 | H1) is a conditional probability that the data D3 is obtained when the occupant is in the low awake state with respect to the data D3 that is the value of the P_vel pattern, and P (D3 | H2) is This is a conditional probability that data D3 is obtained when the user is in the awake state.

  The P_vel pattern is different from the value of the P_velmean that differs depending on the characteristics of the individual, and shows a certain tendency regardless of the characteristics of the individual. Therefore, the P_vel pattern is suitable for determining the arousal state of the person. That is, since the Bayesian filter includes (D3 | H1) and (D3 | H2) related to the P_vel pattern in the likelihood, it is possible to more accurately determine the awake state of the seated person.

  Next, when Equation 2 holds when the respective probabilities are substituted into Equation 2 above, that is, when the value on the left side is greater than the value on the right side (S18: Y), the CPU 12p Determines that the seated person is in the low awake state (S19). On the other hand, when Expression 2 is not satisfied, that is, when the value on the left side is equal to or smaller than the value on the right side (S18: N), the CPU 12p determines that the seated person is in the awake state (S20). When the processing in S19 or S20 is completed, the CPU 12p exits the awake state determination processing.

  Note that, in the section for calculating RIm, which is the average value of RI in S13, and the section for calculating RrMSSD in S14, 30 seconds is defined as one section. However, the present invention is not limited to this, and 20 to 300 seconds may be defined as one section. . The longer this section is set, the slower the awakening determination is, but the greater the number of extracted data for averaging each parameter, the higher the reliability of the awakening determination.

  In the above embodiment, the respective ranges of the RIm that is the data D1 to which the Bayes filter is applied, the P_velmean that is the data D2, and the P_vel pattern that is the data D3 are examples. That is, these ranges may be subdivided, the ranges may be widened, or the number of ranges may be increased or decreased.

  Here, returning to the sequence diagram of FIG. 15, the description will be continued. The CPU 12p of the awake device D transmits the determination result (low awake state / awake state) in S213 to the wireless communication terminal 2 via the wireless communication unit 12A (S214).

  When the control unit 2A of the wireless communication terminal 2 receives the determination result of the awake state from the awakening device D via the wireless communication unit 2C (S111), the received determination result is displayed on the display unit 2E, for example, on the management list screen W2. Is displayed (S112). Note that, when there are a plurality of wake-up devices D that communicate with the wireless communication terminal 2, the above-described process of transmitting the determination result from the wake-up devices D is performed for each of the plurality of wake-up devices D.

  FIG. 20 shows an example of the management list screen W2. As shown in FIG. 20, the management list screen W2 includes a chair ID display area e11, an awake state display area e12, a batch execution button e13, execution buttons e13a and e13b, operation screen display buttons e14a to e14d, and a timer setting screen display. Button e15 is displayed.

  The chair ID display area e11 is a display area for displaying identification information for identifying the chair S to be managed. The awake state display area e12 is a display area that displays the determination result (low awake / awake) received from the awake device D of each chair S.

  When the awake state determined for the occupant of the chair S is “low awake”, an execution button for operating the vibration motor 13 of the awake device D is displayed. In the example illustrated in FIG. 20, since it is determined that the occupants of the chairs S whose identification information is “A” and “C” are low awake, the vibration motor 13 provided in each chair S is operated. An execute button e13a and an execute button e13b are displayed. The collective execution button e13 is an operation unit for collectively operating the vibration motor 13 for each chair S determined to be low awake.

  The operation screen display buttons e14a to e14d are operation units for displaying an operation screen W1 for individually operating each chair S displayed on the management list screen W2. The timer setting screen display button e15 is an operation unit that displays a setting screen (timer setting screen W3 described later) for setting a timer for driving each chair S at a designated time.

  Here, the control unit 2A of the wireless communication terminal 2 accepts the pressing of the batch execution button e13 (the execution button e13a or the execution button e13b) of the management list screen W2 by the input unit 2D, thereby receiving the driving operation of the vibration motor 13. Then, the drive signal of the vibration motor 13 is transmitted to the target awakening device D (S114).

  When the wireless communication unit 12A of the awakening device D receives a drive signal from the wireless communication terminal 2 (S215), the CPU 12p of the awakening device D drives the vibration motor 13 based on the drive signal and executes a driving process (S216). ).

  When the driving of the vibration motor 13 is not ended (S217: N), the CPU 12p of the awakening device D continues the driving of the vibration motor 13 and when the driving of the vibration motor 13 is ended (S217: Y), The driving of the vibration motor 13 is stopped (S218). For example, when the CPU 12p of the awakening device D receives a stop signal for stopping the driving of the vibration motor 13 from the wireless communication terminal 2, or when the continuous driving time of the vibration motor 13 reaches a predetermined time, the CPU 12p of the vibration motor 13 The driving may be terminated. The above is an example of the state display processing and the vibration processing of the seated person.

[Awakening support processing]
Next, an example of the awakening support process executed in the awakening device D will be described with reference to FIG. Note that the awakening support process is to provide a vibration stimulus to the occupant by driving the vibration motor 13 when the awake state determined for the occupant is low awake, and the occupant recovers to the awake state, or This is a process for making it easier to maintain.

  In addition, since steps S31 to S38 in the awakening support process shown in FIG. 17 are the same as steps S11 to S18 in the awake state determination process shown in FIG. 16, only the differences will be described below.

  As shown in FIG. 17, first, when the awakening support function is set to OFF (S30: N), the CPU 12p of the awakening device D ends the process, and when the awakening support function is set to ON. (S30: Y), S31 is executed.

  When the CPU 12p of the awakening device D determines that the occupant is in the awake state by the Bayes filter in S38 (S38: N), the process returns to S31, and when the CPU 12p determines that the occupant is in the low awake state by the Bayes filter (S38). : Y), the vibration motor 13 is driven (S39). Then, the CPU 12p of the awakening device D continues to drive the vibration motor 13 for a predetermined time, and after applying a vibration stimulus to the occupant for a predetermined time (S40), stops the vibration motor 13 (S41).

  Then, if there is no instruction to end (S42: N), the CPU 12p of the awakening device D returns to S31, and if there is an instruction to end (S42: Y), ends the process. For example, the CPU 12p of the awakening device D may end the process when receiving a switch signal for turning off the awakening support function from the wireless communication terminal 2. The above is an example of the awakening support process.

  According to the awakening support process described above, the vibration motor 13 can be driven in a timely manner when the occupant is determined to be in the low awake state, and the awakening of the occupant can be maintained effectively.

[Timer setting process and drive control process]
Next, a timer setting process executed in the state monitoring system 1 and a drive control process of the vibration motor 13 based on the timer setting will be described with reference to a sequence diagram shown in FIG. Prior to the processing in FIG. 18, it is assumed that time information is transmitted from the wireless communication terminal 2 to the awakening device D, and the time information of both devices is synchronized.

  As shown in FIG. 18, the control unit 2A of the wireless communication terminal 2 displays the timer setting screen W3 on the display unit 2E based on the operation received by the input unit 2D (S121). For example, when the control unit 2A of the wireless communication terminal 2 receives the press of the timer setting screen display button e15 of the management list screen W2 while displaying the management list screen W2 on the display unit 2E, the control unit 2A changes the timer setting screen W3 It may be displayed.

  FIG. 21 shows an example of the timer setting screen W3. As shown in FIG. 21, the chair setting screen W3 displays a chair ID display area e21, an operation date and time setting area e22, check boxes e23a to e23d, a setting button e24, a setting addition button e25, and a management list screen display button e26. Is done.

  The chair ID display area e21 is a display area for displaying identification information for identifying the chair S to be managed. The operation date and time setting area e22 is an input area for setting the date and time when the vibration motor 13 is driven.

  Each of the check boxes e23a to e23d is a check box for selecting a chair S to be set for the timer among the chairs S displayed on the timer setting screen W3. The chair S whose check box is checked is a target of the timer setting. Specifically, in the example shown in FIG. 21, since the check boxes e23a and e23b are checked, the chair S whose identification information is “A” and “B” is selected as a timer setting target. It is in a state of being left.

  The setting button e24 is an operation unit for executing a timer setting based on the information set on the timer setting screen W3. The setting addition button e25 is an operation unit for setting another timer, and the management list screen display button e26 is an operation unit for displaying the management list screen W2.

  Here, the control unit 2A of the wireless communication terminal 2 receives the setting of the timer via the timer setting screen W3 (S122), and receives the selection of the chair S to be set for the timer (S123). Thereafter, when the pressing of the setting button e24 of the timer setting screen W3 is received, the control unit 2A of the wireless communication terminal 2 transmits the timer setting information to the awakening device D of the chair S selected in S123 (S124). .

  When the wireless communication unit 12A of the awakening device D receives the timer setting information from the wireless communication terminal 2 (S221), the CPU 12p sets the drive start time of the vibration motor 13 based on the received timer setting information (S222). .

  If the drive start time set in S222 has not arrived (S223: N), the CPU 12p of the awakening device D waits, and if the drive start time set in S222 has come (S223: Y), The vibration motor 13 is driven (S224). If the driving of the vibration motor 13 is not terminated (S225: N), the driving of the vibration motor 13 is continued. If the driving of the vibration motor 13 is terminated (S225: Y), the driving of the vibration motor 13 is stopped. The driving is stopped (S226). For example, when the CPU 12p of the awakening device D receives a stop signal for stopping the driving of the vibration motor 13 from the wireless communication terminal 2, or when the continuous driving time of the vibration motor 13 reaches a predetermined time, the CPU 12p of the vibration motor 13 The driving may be terminated. The above is an example of the timer setting process and the drive control process.

  Although only one awakening device D is displayed in FIG. 18, the processes of S221 to S226 are executed in the awakening device D of each chair S selected in S123.

According to the state monitoring system 1 described above, the awake state of the occupant of the chair S can be visualized and confirmed on the wireless communication terminal 2.
Further, according to the state monitoring system 1, the awake state of the occupant can be determined in consideration of the circadian rhythm. Thereby, it is possible to improve the determination accuracy of the awake state of the seated person.
Further, according to the state monitoring system 1, the occupant in the low awake state can be awake by applying a vibration stimulus.
Further, according to the state monitoring system 1, the vibration motor 13 can be remotely controlled by the wireless communication terminal 2.
Further, according to the state monitoring system 1, the ON / OFF of the wake-up support function of the wake-up device D can be switched by operating the wireless communication terminal 2. Accordingly, the chair S does not need to be provided with a switch for switching the awakening support function on and off, so that the number of components constituting the chair S can be reduced.
Further, according to the state monitoring system 1, the vibration motor 13 can be driven based on the timer setting information received from the wireless communication terminal 2. Thereby, the arrival of the predetermined time can be notified to the seated person by the vibration stimulus.
In addition, according to the state monitoring system 1, since a plurality of chairs S can be managed collectively, the state of the occupant of each chair S can be confirmed by visualizing the state.
According to the state monitoring system 1, the operation of the vibration motor 13 of the chair selected from the plurality of chairs S can be controlled.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the main unit 10 includes the configuration for monitoring the state of the occupant and the configuration for applying vibration stimulation to the occupant. You may.

  Also, in the example of the timer setting process and the drive control process illustrated in FIG. 18, the awakening device D determines that the drive start time has arrived and drives the vibration motor 13. The arrival may be determined, and a drive signal may be transmitted to the awakening device D when the drive start time has arrived.

  In the awakening device D, when the value of the pressure measured by the living body sensor 30 (pressure sensor) becomes lower than a predetermined threshold value over a predetermined period (preferably 1 second), power saving is performed. The mode may be shifted to a sleep mode. In this power saving mode, the pressure measurement by the living body sensor 30 (pressure sensor) is performed every predetermined time (for example, every 4 seconds), and when the measured pressure value is lower than a predetermined threshold value, the power saving is performed. The mode may be maintained, and when the measured pressure value is equal to or greater than the predetermined threshold, the power saving mode may be canceled to operate in the normal mode. In this way, when there is no occupant in the chair S, the operation is performed in the power saving mode to suppress power consumption, and the state of the occupant can be monitored immediately at the timing of sitting on the chair S.
