Description

  The present invention relates to an awakening system that supports a comfortable awakening by gradually increasing the output of an awakening light.

  Conventionally, an alarm clock is generally used for getting up. However, the alarm sound is awakened relatively well when it is awakened by an alarm sound in a shallow sleep state (hereinafter referred to as a “sleeping state”). I feel sick.

  Therefore, the sleeper is put into a sleep state by the awakening action of light by starting the illumination of light (hereinafter referred to as awakening light) that brings awakening action to the sleeper from a predetermined time before the set-up time and gradually increasing the illumination output. An awakening system that awakens a sleeper with an alarm sound or the like thereafter is known (see, for example, Patent Document 1). By gradually increasing the output of the awakening light in this way, the sleeper is prevented from being suddenly awakened by an alarm sound or the like from deep sleep, and can be awakened with good mood. However, in such a wake-up system, the sleeper does not always fall asleep due to the wake-up light. There is a risk of becoming.

  Also, paying attention to the fact that sleepers show awakening responses such as increased body movements when they are in a sleep state, equipped with sensors that detect body movements, when body movements exceed a certain threshold at the time of waking up An awakening system that awakens a sleeper by an alarm or the like when an awakening reaction occurs is known (see, for example, Patent Document 2). However, in such an awakening system, if the sleeper's body movement is not detected around the wake-up time, the sleeper is awakened by an alarm at the wake-up time, resulting in a sudden wake-up and a feeling of awakening . Therefore, if the detection sensitivity of the sensor is increased, the sleeper may be determined to be in a sleep state but not in a sleep state, and may be caused by an alarm or the like to become uncomfortable.

  An awakening system according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the awakening system 1 includes a lighting unit 2 that emits awakening light that awakens a sleeper, a sound source unit 3 that rings, a control that controls the output of the lighting unit 2, the ringing of the sound source unit 3, and the like. Unit 4, a calculation unit 5 for calculating data such as time, an interface unit 6 for a user to make various settings, a clock unit 7 for measuring time, and detecting a body motion of a sleeper A sensor unit (detection means) 8 that outputs a signal to the control unit 4 is provided. The illuminating unit 2 outputs the wakeful light gradually increased under the control of the control unit 4, and may be any light source such as an incandescent light bulb or an LED, and is provided so that the wakeful light illuminates the sleeper's face. It is done. The sound source unit 3 is a sound source that emits an alarm sound that prompts the user to wake up at the wake-up set time under the control of the control unit 4, and is, for example, a buzzer or a speaker. The control unit 4 controls the lighting unit 2, the sound source unit 3, and the like based on the sleeper's body movement detected by the sensor unit 8 and the wake-up setting time. The control unit 4 starts illumination of the illumination unit 2 a predetermined time before the wake-up set time, performs illumination with a gradual increase pattern that gradually increases the light output with time and maximizes the light output at the wake-up set time, and sleeps. Awaken the person. Further, when the control unit 4 determines that the sleeper is in a sleep state based on the body motion detection signal from the sensor unit 8, the control unit 4 performs illumination with a rapid increase pattern that increases the illumination output earlier than the gradual increase pattern. .

  The calculation unit 5 calculates the lighting start time and the like based on the wake-up set time, and transmits the calculation result to the control unit 4. The interface unit 6 performs operations such as setting the wake-up time, turning on / off the alarm sound, adjusting the output of the illumination, turning on / off, etc. using a dial, a numeric keypad, etc., and a display unit such as a liquid crystal display for displaying the current time etc. Have. The clock unit 7 measures the time and transmits the time to the control unit 4. The sensor unit 8 is a sensor such as a piezoelectric sensor installed on or under the bedding, an acceleration sensor mounted on the user's arm or the like, or a non-contact infrared sensor having a detection area on the user's body or bedding. Yes, the body motion detection signal output by each sensor is transmitted to the control unit 4. The control unit 4 determines that the sleeper is in a sleep state and exhibits an arousal reaction when the body motion detection signal satisfies a predetermined sleep sleep criterion.

  FIG. 2A shows an arrangement configuration of each part of the awakening system 1. The awakening system 1 includes a housing 9 and various parts such as a lighting unit 2 and a sound source unit 3. The awakening system 1 is arranged near the head of the sleeper so that the interface unit 6 can be easily operated. The illumination unit 2 is provided such that the sleeper's head enters the illumination area. In this example, the sensor unit 8 is an infrared sensor, and the entire bedding from the sleeper's head is used as a detection region. 4 is output. When the sensor unit 8 is a piezoelectric sensor, a body motion detection signal is output to the control unit 4 based on the magnitude of pressure detected by the piezoelectric sensor and the frequency of pressure fluctuation. When the sensor unit 8 is an acceleration sensor, a body motion detection signal is output to the control unit 4 based on the magnitude of the acceleration detected by the acceleration sensor or the frequency at which an acceleration greater than a predetermined magnitude is detected. FIG. 2B shows another configuration example of the awakening system 1. In this example, the illumination unit 2 is provided on the ceiling. The illumination unit 2 is controlled by a wired signal or a wireless signal such as infrared rays from the control unit 4. Since the entire room is illuminated from the ceiling, the awakening light can be gradually increased to a state close to natural dawn.

  An example of the operation of the awakening system 1 will be described with reference to FIG. When the wake-up setting time is set in the interface unit 6, the calculation unit 5 calculates a lighting start time that is a predetermined time earlier than the wake-up setting time, and transmits the lighting start time to the control unit 4. In the example shown in FIG. 3A, the illumination start time is set 30 minutes earlier than the set-up time. When the illumination start time comes, the control unit 4 starts illumination of the illumination unit 2 and detection of body movement by the sensor unit 8, and increases the illumination output based on a predetermined gradual increase pattern (indicated by a broken line).

  FIG. 3 (b) shows the criteria for determining sleep. When the body motion detection signal received from the sensor unit 8 satisfies a predetermined sleep sleep criterion in the course of gradually increasing the wake light, the control unit 4 enters a sleep state and exhibits a wake reaction. Illumination is continued by a rapid increase pattern (indicated by a solid line in FIG. 3A) that increases the output earlier than the gradual increase pattern. Due to this rapid increase pattern, the awakening light reaches the maximum illuminance earlier than the set-up time. At the wake-up set time, an alarm is sounded by the sound source unit 3, but the sounding of the sound source unit 3 may be stopped by operating the interface unit 6. The sleep sleep criterion is set so that the closer to the lighting start time, the less likely it is to be in a sleep state, and the easier it is to determine the sleep state as time passes and the wake-up set time is approached.

  Next, an example of a body motion detection signal and a sleep sleep determination criterion will be described with reference to FIG. The body movement detection signal is output when the sensor unit 8 detects body movement. In this example, the intensity of the body motion detection signal is constant regardless of the size of the detected body motion, and if the motion time of the body motion is within a predetermined time, the output time length of the body motion detection signal is also It is assumed to be constant. When the motion time of the body motion exceeds a predetermined time, a new body motion detection signal is output. When the number of detections per fixed time exceeds a predetermined number of times reference value, it is determined that the patient is in a sleep state. In FIG. 4, three body movements are detected and three body movement detection signals are output. Further, the reference number of times is set so as to become smaller from the lighting start time to the wake-up setting time.

  According to the awakening system 1 of the present embodiment, the sleeper is not in a sleep state because it is difficult to be determined to be in a sleep state in a time zone close to the illumination start time because of the setting as described above. Therefore, it is determined that the patient is in a sleep state, and the light output is increased. Also, since it is easy to be determined to be in a sleep state in a time zone close to the set-up time, even if the sleeper is in a sleep state, it is determined that the sleeper is not in a sleep state and the lighting output does not increase. The risk of not being brought from the sleep state to the awake state is reduced. Therefore, a comfortable awakening of the sleeper can be supported by gradually increasing the awakening light without causing the sleeper to feel uncomfortable. If it is not determined that the patient is in a sleep state between the start of lighting of the wake-up light and the set-up time, the control unit 4 gradually increases the illumination output to a maximum with a predetermined gradual increase pattern. Thereby, even when the sleep dormant criterion is not satisfied before the set-up time, the awakening of the sleeper can be supported by the gradually increasing awakening light.

  A first modification of the body motion detection signal and the sleep-sleep determination criterion will be described with reference to FIG. In this modification, the body motion detection signal is output when the sensor unit 8 detects body motion, and the signal strength of the body motion detection signal increases according to the magnitude of the body motion. Then, when the number of detections of the body motion detection signal exceeding a predetermined strength reference value per predetermined time exceeds a predetermined number of times reference value, it is determined that the patient is in a sleep state. This intensity reference value is set so as to become smaller as it approaches the wake-up setting time from the illumination start time. In FIG. 5, the number of detections of the body motion detection signal exceeding the intensity reference value is two.

  In this modification, the closer to the lighting start time based on the signal intensity, the less likely it is to be determined to be in a sleep state, and the closer to the set-up time, the easier it is to determine that the patient is in a sleep state. Get better.

  Next, a second modification example of the body motion detection signal and the sleep-sleep determination criterion will be described with reference to FIG. In this modification, the body movement detection signal is output when the sensor unit 8 detects body movement, and the signal intensity of the body movement detection signal increases according to the magnitude of the body movement as in the first modification. When the integrated value per certain time of the signal intensity of the body motion detection signal exceeds a predetermined integrated reference value, it is determined that the patient is in a sleep state. This integrated reference value is set so as to become smaller as it approaches the wake-up setting time from the illumination start time. In FIG. 6, the signal intensities of the body motion detection signals A, B, and C are integrated and compared with the integrated reference value.

  In this modified example, the closer to the lighting start time, the less likely it is to be in a sleep state based on the integrated value of the signal intensity. The accuracy is better.

  Another example of this modification will be described with reference to FIG. In this example, the output time length of the body motion detection signal is changed according to the motion time of the body motion, and the integrated value of the area based on the waveform of the body motion detection signal is used as the integrated value of the signal intensity. Then, when the integrated value per unit time of the area based on the waveform of the body motion detection signal exceeds a predetermined integrated reference value, it is determined that the patient is in a sleep state. In the example of FIG. 7, the areas of the shaded portions of the body motion detection signals D, E, and F are integrated and compared with the integrated reference value. By determining in this way, based on the integrated value of the area of the body motion detection signal, the closer to the illumination start time, the less likely it is to be determined to be in a sleep state, and the closer to the set-up time, the more likely it is to be in a sleep state. Since it becomes easy, the accuracy of judgment becomes better.

  Next, a third modified example of the body motion detection signal and the sleep-sleep determination criterion will be described with reference to FIG. In this modification, the detection time for detecting body movement is different from the above-described embodiment. The body movement detection signal is output when the sensor unit 8 detects body movement as in the above-described embodiment. Then, when the number of detections by which the sensor unit 8 detects body movement within a predetermined detection time exceeds a predetermined number of times reference value, it is determined that the patient is in a sleep state, and approaches the wake-up set time from the illumination start time. The detection time is set to be long. At this time, the reference number of times remains constant. As a result, the closer to the lighting start time based on the number of body movement detections, the less likely it is to be determined to be in a sleep state. Get better.

  Another example of this modification will be described. In the asymmetry determination criterion of the second modified example described above, the detection time, which is a period during which signal strength is integrated, is set to become longer as it approaches the wake-up setting time from the illumination start time. As a result, the closer to the lighting start time based on the integrated value of the signal intensity, the less likely it is to be determined to be in a sleep state. Get better.

  In addition, this invention is not restricted to the structure of the said embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, when a wakefulness reaction is detected, illumination may be performed by reducing the time axis of the gradually increasing pattern without using the fast increasing pattern.
