Description

  The present invention relates to an alarm device and a portable information terminal, and more particularly to an improvement of an alarm device that outputs an alarm sound.

  Patent Document 1 describes a system that receives an earthquake early warning transmitted by the Japan Meteorological Agency via the Internet and warns the user by voice or display. According to this system, it is possible to promptly notify the user that an earthquake has occurred. However, in such a system, earthquake notification is performed regardless of whether the user is awake or asleep.

  For this reason, for an awakened user, although the user is aware that an earthquake has occurred, an alarm sound is heard and it is annoying, while for a user in the sleep state, the alarm sound may not be noticed. There was a problem.

  Moreover, in the conventional notification system as described above, earthquake notification is performed regardless of the magnitude of shaking. For this reason, there was a problem that the earthquake notification was performed even though the seismic intensity was small and the urgency was low, and the alarm releasing operation was troublesome.

<Earthquake Notification System 100>
FIG. 1 is a system diagram showing a configuration example of an earthquake notification system 100 including an alarm device 1 according to an embodiment of the present invention. The earthquake notification system 100 includes an alarm device 1, a communication network 2, a wireless AP (access point) 3, and a server device 40, and seismic intensity information generated immediately after the occurrence of an earthquake is transmitted from the server device 40 to the alarm device. 1 and an alarm sound is output.

  The seismic intensity information is information indicating the magnitude of the shaking, and includes data representing the seismic intensity class. For example, seismic intensity information detects the occurrence of an earthquake based on observation data from seismometers installed in various locations, analyzes seismic wave data observed by seismometers close to the epicenter, and determines the location of the epicenter and the magnitude of the earthquake. It is created by estimating and determining the seismic intensity class of each place based on the estimation result.

  The server device 40 is a terminal device that holds such seismic intensity information in the seismic intensity information storage unit 41, and is connected to the communication network 2. Each time new seismic intensity information is stored in the seismic intensity information storage unit 41, the server apparatus 40 transmits the seismic intensity information to the reporting apparatus 1 via the communication network 2.

  The communication network 2 is configured by the Internet, a local area network, a mobile line network, and the like. The seismic intensity information is transmitted to the alarm device 1 via the wireless AP 3 on the communication network 2. The wireless AP 3 is a relay device for wireless communication.

  The alarm device 1 includes a portable information terminal 10, a biological information measuring device 20, and a notification device 30, and outputs an alarm sound based on seismic intensity information received from the server device 40 via the wireless AP 3.

  The portable information terminal 10 is a client terminal that communicates with the wireless AP 3 and receives seismic intensity information from the server device 40. For example, the mobile information terminal 10 is notified of seismic intensity information corresponding to the current position by e-mail as an emergency earthquake bulletin. For example, the mobile information terminal 10 is a mobile phone that communicates with a base station as the wireless AP 3 and makes a call with another communication terminal via a mobile network.

  The biological information measuring device 20 is a biological information measuring unit that measures the biological information of the person to be notified and transmits the measurement result to the portable information terminal 10. In this biological information measuring device 20, vital signs such as a pulse are measured as biological information from the notification subject.

  The notification device 30 is a warning output device that outputs a warning sound, and notifies the notification target person that an earthquake has occurred by outputting a warning sound. The portable information terminal 10 wirelessly communicates with the biological information measuring device 20 and the notification device 30, acquires the notification subject's biological information from the biological information measurement device 20 and determines the sleep state of the notification subject, A notification request designating the sound volume level is generated and transmitted to the notification device 30.

  The sleep state is a physical state in which the level of consciousness is temporarily reduced, and is a state in which a person can wake up spontaneously. Whether it is a sleep state or an arousal state can be identified by a state such as a pulse.

  In the portable information terminal 10, immediately after receiving the seismic intensity information from the server device 40, a biological information transmission request is transmitted to the biological information measuring device 20. Based on the transmission request from the portable information terminal 10, the biological information measuring device 20 transmits the biological information measured within a certain period including the time when the transmission request is received to the requesting portable information terminal 10. That is, the portable information terminal 10 can acquire biological information measured within a certain period including the time when the seismic intensity information is received.

  Moreover, in the portable information terminal 10, based on the biological information acquired from the biological information measuring device 20, it is determined whether or not the notification target person is in a sleep state. Then, based on the sleep state determination result and the seismic intensity information received from the server device 40, a notification request specifying the volume level of the alarm sound is generated.

  When the notification device 30 outputs a warning sound based on a notification request from the portable information terminal 10, the notification device 30 outputs a warning sound at a designated volume level. In other words, the notification device 30 can vary the volume level of the alarm sound according to the depth of sleep and the magnitude of shaking of the notification subject.

The biological information measuring device 20 includes a pulse sensor 21, a body motion sensor 22, a temperature sensor 23, a potential sensor 24, a biological information generation unit 25, and a short-range wireless communication unit 26. For example, the biological information measuring device 20 is a wristband type electronic device that is worn on the wrist of the person to be notified.

  The pulse sensor 21 detects the notification subject's pulse, and outputs the detection result to the biological information generation unit 25. The pulse is a pulsation that occurs when the heart pumps blood to the artery, and the number of pulsations within a certain time is detected as biological information.

  The body motion sensor 22 detects the body motion of the notification target person and outputs the detection result to the biological information generation unit 25. The body movement is a body movement such as turning over, and the number of body movements within a predetermined time is detected as biological information. The temperature sensor 23 detects the notification subject's skin temperature and outputs the detection result to the biological information generation unit 25. The potential sensor 24 detects the skin potential of the notification subject and outputs the detection result to the biological information generation unit 25.

  The biological information generation unit 25 generates biological information based on outputs from the pulse sensor 21, body motion sensor 22, temperature sensor 23, and potential sensor 24.

For example, the short-range wireless communication unit 26 performs wireless communication using a communication standard communication method such as Bluetooth (registered trademark).

  Based on the transmission request from the portable information terminal 10, the biological information generation unit 25 transmits the biological information to the requesting portable information terminal 10 via the short-range wireless communication unit 26. That is, the biological information measured within a certain period including the time when the transmission request is received is transmitted to the portable information terminal 10 that is the transmission source of the transmission request. For example, the biological information measured immediately before receiving the transmission request or measured immediately after receiving the transmission request is transmitted to the portable information terminal 10.

<Notification device 30>
FIG. 3 is a block diagram showing a configuration example of the notification device 30 of FIG. The notification device 30 includes a short-range wireless communication unit 31, a notification control unit 32, a speaker 33, an LED 34, and an LCD 35, and outputs an alarm sound to the notification target person that an earthquake has occurred, the lighting of the LED 34, and the LCD 35. Notification is made by displaying. For example, a lighting device, a TV (television) receiver, an audio device, or the like installed in the home of the person to be notified is used as the notification device 30.

  The short-range wireless communication unit 31 performs wireless communication with the portable information terminal 10 using weak radio waves. For example, the short-range wireless communication unit 31 performs wireless communication using a communication standard communication method such as Bluetooth. The notification control unit 32 drives the speaker 33, the LED 34, and the LCD 35 based on the notification request from the portable information terminal 10.

  The speaker 33 is an alarm output unit that outputs an alarm sound at a volume level designated by the notification control unit 32. As the alarm sound, an electronic sound consisting of an audible frequency band signal such as a buzzer sound or a chime sound, or a voice message indicating that an earthquake has occurred is used.

The LCD (liquid crystal display) 35 is a display device that displays an image at a luminance level specified by the notification control unit 32. The light intensity level of the illumination light and the luminance level of the video display are determined according to the volume level of the alarm sound.

<Portable information terminal 10>
FIG. 4 is a block diagram showing a configuration example of the portable information terminal 10 of FIG. The portable information terminal 10 includes a cellular communication unit 11, a notification control unit 12, a seismic intensity information storage unit 13, a biological information acquisition unit 14, a short-range communication unit 15, a biological information storage unit 16, a sleep state determination unit 17, and a volume level designation. The unit 18 and the notification request generation unit 19 are configured.

  The cellular communication unit 11 performs wireless communication with the wireless AP 3 (base station) and receives seismic intensity information from the server device 40. The notification control unit 12 stores the received seismic intensity information in the seismic intensity information storage unit 13 and instructs the biometric information acquisition unit 14 to acquire biometric information. The short-range communication unit 15 performs wireless communication between the biological information measuring device 20 and the notification device 30 using weak radio waves.

  The biological information acquisition unit 14 generates a transmission request for acquiring biological information after receiving the seismic intensity information, and transmits the transmission request to the biological information measurement device 20 via the short-range communication unit 15, while the biological information measurement device 20. The biometric information received from is stored in the biometric information storage unit 16.

  The sleep state determination unit 17 determines whether or not the notification target person is in a sleep state based on the biological information in the biological information storage unit 16 and outputs the determination result to the volume level designation unit 18. The sleep state is determined based on biological information measured within a certain period including the time when the seismic intensity information is received. The sleep state determination unit 17 determines whether the notification target person corresponds to any of three or more sleep levels including an awake state and two or more sleep states having different depths.

  Generally, the pulse is less as the depth of sleep (sleep depth) is deeper, and the pulse is increased when sleep is shallower. Moreover, the pulse in the sleep state is reduced by about 20% to 30% as compared with the awake state. Therefore, by measuring the pulse of the notification target person as biological information, it is possible to accurately determine which of the three or more sleep levels the notification target person corresponds to.

  For example, it is determined which one of the six sleep levels including one awakening stage and five sleep stages is applicable. The sleep stage includes one REM (REM) sleep stage and four non-REM (NREM) sleep stage stages 1 to 4.

  The sleep depth is large in the order of the awakening stage, the REM sleep stage, and the non-REM sleep stage stage 1 to stage 4. In particular, the non-REM sleep stage 3 and stage 4 may be referred to as deep sleep stages.

  Specifically, the pulse value in the awake state is held in advance, and the sleep level is determined based on this pulse value. For example, if the pulse value in the awake state is 100, a pulse value of 100 or more is the awakening stage, and a pulse value of 96 or more and less than 100 is the REM sleep stage. Further, a pulse value of 92 or more and less than 96 is the non-REM sleep stage 1, and a pulse value of 88 or more and less than 92 is the non-REM sleep stage 2. The pulse value of 84 or more and less than 88 is the non-REM sleep stage 3 and the pulse value of less than 84 is the non-REM sleep stage 4.

  If multiple items of biological information such as body movement, skin temperature, and skin potential, including the pulse, are obtained, the sleep level of the notification subject may be determined using these multiple items of biological information. . For example, a configuration in which the sleep level of the notification subject is calculated by a weighted average of the sleep level estimated from the pulse and the sleep level estimated from the body motion is conceivable.

  The volume level designation unit 18 designates the volume level of the alarm sound based on the sleep state determination result by the sleep state determination unit 17 and the seismic intensity information in the seismic intensity information storage unit 13. That is, when the notification target person is in a sleep state, the volume level of the alarm sound is increased more than in the case of being in an awakening state. Moreover, the volume level designation | designated part 18 increases the volume level of an alarm sound, so that the depth of a sleep state increases, and increases the volume level of an alarm sound, so that a seismic intensity class increases.

  The notification request generator 19 generates a notification request specifying the volume level of the alarm sound and outputs the notification request to the short-range communication unit 15. The short-range communication unit 15 transmits this notification request to the notification device 30. In the notification device 30, when outputting a warning sound based on a notification request from the portable information terminal 10, as the depth of the sleep state increases, the volume level of the warning sound increases and the seismic intensity class increases. Increase the volume level of the alarm sound.

  FIG. 5 is an explanatory diagram schematically showing an example of usage modes of the portable information terminal 10, the biological information measuring device 20, and the notification device 30, and shows a situation in the home 5 of the notification target person 4. The home 5 has a kitchen K and a living room LR on the first floor, and a bedroom BR and a children's room CR on the second floor.

  The kitchen K, the living room LR, the bedroom BR, and the child room CR are each provided with a lighting device 30a, and the living room LR is provided with a TV image receiving device 30b and an audio device 30c. The illumination device 30a, the TV receiver 30b, and the audio device 30c function as the notification device 30.

  The biological information measuring device 20 is in the bedroom BR together with the notification subject 4, and the portable information terminal 10 is in the living room LR. The internal space of the home 5 is a short-range wireless communication area, and the portable information terminal 10 is connected to the living body information measuring device 20, the lighting device 30 a, the TV receiver 30 b, and any room in the home 5. It can communicate with the audio device 30c.

  That is, since the notification request designating the volume level of the alarm sound is transmitted to the lighting device 30a, the TV receiver 30b, and the audio device 30c, the notification subject 4 is awake regardless of where the notification target 4 is in the home 5. It is possible to output an alarm sound at an appropriate volume level depending on whether it is a state or a sleep state.

  FIG. 6 is a sequence diagram showing an example of an operation when an earthquake occurs in the earthquake notification system 100 of FIG. First, when the earthquake early warning is notified from the server device 40, the portable information terminal 10 transmits a biometric information transmission request to the biometric information measuring device 20. The biometric information measuring device 20 measures the biometric information of the notification target person 4 every predetermined time T1, and if there is a transmission request from the portable information terminal 10, based on the transmission request, the biometric information is requested from the portable information terminal of the request source. 10 to send.

  Next, the portable information terminal 10 determines the sleep state of the notification target person 4 based on the biological information acquired from the biological information measuring device 20 (step S101), and based on the determination result and the seismic intensity class, A sound volume level is designated (step S102). The portable information terminal 10 transmits a notification request specifying the volume level of the alarm sound to the notification device 30.

  If there is a notification request from the portable information terminal 10, the notification device 30 outputs an alarm sound based on the notification request (step S103). At that time, when the notification target person 4 is in the sleep state, the volume level of the alarm sound is increased more than in the case of the awake state. For this reason, it is possible to output an alarm sound at an appropriate volume level according to whether or not the notification subject person 4 is in a sleep state. Moreover, the volume level of the alarm sound is increased as the seismic intensity class is increased. For this reason, at the time of the occurrence of an earthquake, an alarm sound can be output at an appropriate volume level according to whether or not the notification subject 4 is in a sleep state and the magnitude of shaking.

<Volume level judgment table>
FIG. 7 is a diagram showing an example of a volume level determination table used in the portable information terminal 10 of FIG. In this figure, the volume level is divided into seven levels from level 0 corresponding to the silence level to level 6 corresponding to the upper limit level. This table is an assignment table in which a volume level of an alarm sound is assigned to each combination of six sleep levels and seven seismic intensity classes.

  Specifically, for each seismic intensity class of seismic intensity 3 or higher, the volume level increases as the sleep depth increases, and for each sleep stage, the sound volume level increases as the seismic intensity class increases. Assigned.

  For example, in seismic intensity 1 or 2, it is considered that there is no need for notification, and level 0 is assigned to these seismic intensity classes regardless of the sleep level. Further, it is considered that no notification is required even in the awakening stage, and level 0 is assigned to the awakening stage regardless of the seismic intensity class. That is, if the seismic intensity class is less than seismic intensity 2 or the sleep level is the awakening stage, level 0 is assigned.

  On the other hand, at seismic intensity 3, level 1 is assigned to each sleep stage from the REM sleep stage to stage 2 of the non-REM sleep stage, and level 2 is assigned to stages 3 and 4 of the non-REM sleep stage. In seismic intensity 4, level 2 is assigned to each sleep stage from the REM sleep stage to stage 2 of the non-REM sleep stage, and level 3 is assigned to stages 3 and 4 of the non-REM sleep stage.

  At seismic intensity 5, level 3 is assigned to each sleep stage from the REM sleep stage to stage 2 of the non-REM sleep stage, and level 4 is assigned to stages 3 and 4 of the non-REM sleep stage. At seismic intensity 6, level 4 is assigned to each sleep stage from the REM sleep stage to stage 2 of the non-REM sleep stage, and level 5 is assigned to stages 3 and 4 of the non-REM sleep stage.

  In the seismic intensity class of seismic intensity 7 or higher, level 5 is assigned to each sleep stage from the REM sleep stage to stage 2 of the non-REM sleep stage, and level 6 is assigned to stages 3 and 4 of the non-REM sleep stage. . The volume level designation unit 18 designates a volume level corresponding to the seismic intensity class of the earthquake and the sleep level of the notification subject 4 using such a table.

  Steps S201 to S209 in FIG. 8 are flowcharts showing an example of the operation at the time of receiving seismic intensity information in the portable information terminal 10 in FIG. First, the biometric information acquisition unit 14 generates a biometric information transmission request and transmits the biometric information transmission request to the biometric information measurement device 20 via the short-range communication unit 15 (step S201).

  Next, if biometric information is received from the biometric information measuring device 20, the biometric information acquisition unit 14 stores the biometric information in the biometric information storage unit 16 (step S202). On the other hand, the biometric information acquisition unit 14 generates a notification request specifying the volume level of the alarm sound when the biometric information is not received by the time T2 elapses after the transmission request is transmitted, and the short-range communication unit 15 To the notification device 30 (steps S208 and S209). In this case, since it is considered that the person to be notified 4 is not wearing the biological information measuring device 20, a notification request in which the volume level of the alarm sound is designated as the upper limit level, that is, level 6 is generated. Thereby, it is possible to notify the notification target person 4 who is not wearing the biological information measuring device 20 that an earthquake has occurred.

  Next, the sleep state determination unit 17 determines the sleep state of the notification target person 4 based on the biological information stored in the biological information storage unit 16 (step S203). The volume level designation unit 18 designates the volume level of the alarm sound based on the sleep state determination result and seismic intensity information (step S204).

  The notification request generation unit 19 generates a notification request specifying the volume level of the alarm sound when the volume level specified by the volume level specification unit 18 is level 1 or higher, and notifies the notification request via the short-range communication unit 15. It transmits to the apparatus 30 (step S205, S206).

  If a certain time T3 has elapsed since the notification request was transmitted, the processing procedure after step S201 is repeated (step S207). That is, it is possible to detect that the notification target person 4 has awakened from the sleep state and automatically stop the output of the alarm sound. On the other hand, if the volume level is level 0, the notification request generator 19 ends this process without transmitting a notification request.

  According to the present embodiment, the sleep state of the notification subject 4 is determined based on the biological information, and the volume level of the alarm sound is controlled based on the determination result. At that time, when the notification target person 4 is in the sleep state, the volume level of the alarm sound is increased more than in the case of the awake state. For this reason, it is possible to output an alarm sound at an appropriate volume level according to whether or not the notification subject person 4 is in a sleep state. In particular, since the notification target person 4 determines which of the three or more sleep levels corresponds to control the volume level of the alarm sound, the alarm is performed at an appropriate volume level according to the sleep depth of the notification target person 4. Sound can be output.

  Further, when the alarm sound is output after the seismic intensity information is received, the volume level of the alarm sound is increased as the seismic intensity class is increased. For this reason, at the time of the occurrence of an earthquake, an alarm sound can be output at an appropriate volume level according to whether or not the notification subject 4 is in a sleep state and the magnitude of shaking.
