Description

  TECHNICAL FIELD The present invention relates to a fall notification system for making a notification when a subject such as a sick person or an elderly person falls to receive an appropriate treatment.

  For example, when a subject such as a sick person or an elderly person who has some kind of illness falls due to a seizure, rescue arrangements are made promptly from the time of the fall, or appropriate medical measures are taken according to the symptoms As a result, the survival probability can be increased and the prognosis can be improved.

  Therefore, by using a fall notification system that automatically reports to the center when the subject falls over the past, quick relief arrangements from the center and medical treatment to the subject by a specialist It is considered to be able to provide specific advice.

  The present applicant conducts research and development on a daily basis in order to improve the above-described notification system at the time of falling upon receiving the setting of the exclusive license for the patent described in Patent Document 1.

  The doctor call system described in Patent Document 1 includes a terminal device worn by a wearer and a center-side device provided in a center where specialists such as doctors reside.

  The terminal device includes a biosensor for acquiring biometric information such as a wearer's pulse and cardiac current, an acceleration sensor, and a voice presentation device for receiving medical advice from the center-side device.

  The center-side device constantly receives and monitors biological information and acceleration measurement data measured by the terminal device, and notifies the doctor in the center of the abnormality when the measurement data is abnormal. It is configured as follows. When an abnormality is notified, the doctor in the center is determined to provide medical advice to the voice presentation device based on the wearer's measurement data received by the center side device. Yes.

  Furthermore, this doctor call system is configured not only to provide medical advice, but also in the event of an emergency, emergency treatment can be performed remotely from the center via the terminal device. Specifically, the terminal device further includes a stimulus applying mechanism for applying an electrical or physical stimulus to the heart when the wearer's biological information indicates cardiac arrest or apnea. . The stimulus applying mechanism is configured to be driven only when there is a drive command instructed via the center side device when necessity is recognized by a doctor present at the center.

  By the way, the inventors of the present application have conducted extensive studies to improve the above-described doctor call system, and found that the following technical problems exist.

  That is, in the doctor call system, when the biological information or acceleration measured by the terminal device shows an abnormal value as compared with the normal time, the center side device is notified. Since the information that can be referred to by the doctor is only the biological information and acceleration of the wearer, the accurate state of the wearer when the report is made may not be grasped.

  For example, it is conceivable that an abnormal value is indicated because a sensor for detecting biological information is removed from the wearer or shifted to another measurement site. For this reason, even if there is a large change in the measured acceleration and it indicates the possibility of falling, whether or not the stimulus may be applied to the wearer by the stimulus applying mechanism, It can be difficult for doctors to be confident about what to make arrangements.

  Also, even if the measurement data is correct and it can be detected from the acceleration measured by the terminal device that the fall occurred, whether the fall is due to the wearer's disease or a traffic accident, etc. It is also difficult to grasp the detailed situation about the wearer himself. In order to enable a more appropriate treatment on the center side when the wearer falls, it is necessary to configure the system so that more detailed information can be acquired from the time of the fall.

  In addition, with the current doctor call system, if an abnormality occurs in the wearer, the doctor at the center can grasp the wearer's own condition, but it seems to help the wearer. It is difficult for a doctor to properly infer an external situation such as a person or what kind of place an abnormality has occurred.

Japanese Patent No. 4131997

  The present invention has been made in view of the above-described problems, and when a wearer falls, more detailed information on the external situation of the wearer after the fall and the condition of the wearer himself / herself can be obtained. It is an object of the present invention to provide a fall notification system that makes it possible to obtain information, for example, by making it easier for doctors in the center to grasp the situation more easily and take appropriate measures.

  That is, the fall notification system according to the present invention is a fall report unit that outputs a fall report signal that is at least partially worn by the wearer and reports the wearer's fall as in the first aspect of the invention. And a center side device including a fall notification receiving unit that receives the fall notification signal output from the terminal device, and the terminal device further includes a value related to acceleration. A movement measurement sensor for measuring a certain amount of movement, a biological information measurement sensor for measuring the biological information of the wearer, and measurement data measured by the terminal device including the movement amount and the biological information to the center side device A state measurement mechanism composed of a measurement data transmission unit for transmission, and at least a terminal-side microphone and a terminal-side speaker, and enables voice communication with the center-side device A terminal-side call mechanism configured, and a stimulus applying mechanism that gives a stimulus to the wearer when a drive command signal transmitted from the center-side device is received, and the center-side device further includes: A data processing unit that receives at least measurement data transmitted from a terminal device and displays various information based on the measurement data, and a center-side call mechanism configured to enable a voice call between the terminal device And a drive command transmission unit that transmits a drive command signal for driving the stimulus applying mechanism to the terminal device.

  Further, according to the present invention, the terminal device is configured to determine the possibility that the wearer has fallen based on the amount of movement measured by the motion measurement sensor, the camera, A video transmission unit configured to transmit video data captured by the camera to the center-side device, and an on / off control unit configured to switch at least on / off states of the terminal-side microphone and the camera. And the on / off control unit is configured to turn on at least the terminal-side microphone and the camera after the point in time when the wearer has determined that the wearer may have fallen. The terminal-side call mechanism and the video transmission mechanism are determined by the fall possibility determination unit to have a possibility that the wearer has fallen. In the following points, a fall time reporting system, characterized in that the audio and video obtained by the terminal-side microphone and the camera is configured to transmit to the center side device.

  In such a case, at least the terminal-side microphone and the camera are turned on after the on / off control unit determines that the wearer may have fallen by the fall possibility determination unit. Therefore, from the time when the wearer falls, the center side device can know the surrounding external situation imaged by the camera, and the image captured by the camera is shaken. In addition, based on the sound collected by the terminal-side microphone, information on the wearer's own state can also be obtained in the center-side device.

  Therefore, together with the measurement data such as the wearer's biological information and the amount of movement, the center side device can also be used by the center side device for the video and audio after the fall from the viewpoint of the wearer. Since the operator can grasp the situation, when receiving the wearer's fall notification, the situation can be grasped more accurately than before, and more appropriate rescue arrangements and medical advice can be provided to the wearer. It becomes possible.

  Specifically, if the measurement data shows an abnormal value, and the image captured by the camera shows only the ground or the direction of the image is in a strange direction, the center The operator referring to the side device can be sure that the wearer is actually falling. Further, for example, if a car or the like is not shown in the video immediately after the fall, the operator can determine that the fall is due to a seizure or the like of the wearer, and that if the car is shown, it is a traffic accident or the like.

  In addition, since the terminal-side microphone and the camera have been activated since the occurrence of the fall, the center also shows what changes appear when a stimulus is given to the wearer by the stimulus applying mechanism after the fall. It can be monitored by the side device, and can be used for grasping the state of the wearer after the fall.

  In addition, the external situation such as whether there is a person who is likely to help around the wearer who has fallen from the sound around the wearer collected by the microphone on the terminal side or the image captured by the camera The operator can grasp through the center side device.

  From these, the center side device allows the operator to refer to the audio and video after the fall, and to know the detailed situation of the wearer after the fall and the surrounding external situation. The operator who refers to the information can select an appropriate treatment with himself / herself.

In order to reduce the normal power consumption in the terminal device, increase the operation time, and to quickly obtain necessary information when a fall occurs, as in the invention of claim 2 The on / off control unit also switches the on / off state of the biological information measurement sensor, and the biological information measurement sensor is switched on from the time when the wearer may have fallen by the fall possibility determination unit. What is necessary is just to be comprised so that it may be in an ON state.
Considering not only the amount of movement measured by the movement measuring sensor but also biological information measured by the biological information measuring sensor, it is possible to estimate in more detail the activity state before and after the wearer falls. As in the third aspect of the present invention, the biological information measurement sensor only needs to be always on regardless of the determination result of the fall possibility determination unit.

  In order to alert people in need of help in a situation where a fall has occurred and the wearer is unable to cope with the situation, it is easy to receive immediate relief. As described above, after the terminal device is determined by the fall possibility determination unit that the wearer may have fallen, an alarm sound control unit that outputs an alarm sound at a predetermined volume or higher from the terminal-side speaker is provided. Any further provided may be used.

  When a wearer falls, the wearer himself promptly asks an operator or family member who is monitoring the center side device immediately, or cancels the report if he / she can deal with it without any problems. In order to be able to do this, as in the invention according to claim 5, the terminal device further includes an input receiving unit that can be used after the fall reporting unit has transmitted a fall report signal to the center side device. The input reception unit includes a notification cancellation reception unit for stopping transmission of the fall notification signal to the center side device, and an emergency contact point transmission reception unit for starting a call to an emergency contact point Anything can be used.

  From the point in time when the wearer may have fallen, the sound collection and imaging by the terminal microphone and the camera are started, and important information immediately after the fall is leaked in order to grasp the situation in the event of a true fall. In order to enable acquisition by the terminal device, the fall possibility determination unit as described in claim 6 determines in advance the absolute value of the change amount of the motion amount measured by the motion measurement sensor. When the predetermined value is exceeded, the wearer is determined to have a slight possibility that the wearer has fallen, and the on / off control unit causes the wearer to fall by the fall possibility determination unit. It is only necessary that the terminal-side microphone, the camera, and the biological information measurement sensor are turned on from the time when it is determined that there is a slight possibility.

  For example, if there is a movement with a large impact by the wearer, but there is no actual fall, attention is not given to the surroundings, but only when there is a high possibility that the person actually fell In order to ensure that the alerting is performed and the reliability of the alerting can be kept constant, as in the invention according to claim 7, the fall possibility determination unit is a lightness that the wearer has fallen. Since it is determined that there is a possibility that the movement amount measured by the movement amount sensor becomes weaker with the lapse of time or when the state of substantially zero is maintained, there is a possibility that the wearer has fallen severely From the time when the warning sound control unit determines that the wearer may have fallen seriously by the fall possibility determination unit, the warning sound is transmitted from the terminal-side speaker. Output above the specified volume Only it needs to be configured to.

  In order to make it easy to keep track of the time elapsed since the notification was made, while reporting the fall to the center side device only when the wearer really falls When the predetermined time has elapsed after the fall reporting unit has determined that the wearer may have fallen seriously by the fall possibility judging unit as in the invention according to Item 8, the center side device Is configured to transmit a fall notification signal to the fall notification section until the input is accepted by the report cancellation acceptance section after the transmission of the fall notification signal to the center side device is started. What is necessary is just to be comprised so that transmission of the said fall notification signal may be repeated for every predetermined period.

  If the terminal device has reported the fall to the center side device and the time has passed without any action by the wearer or the surrounding people, the situation of the wearer may have deteriorated. high. In order to perform relief according to the change in the urgency level of the wearer after such a fall, the fall report unit, as in the invention according to claim 9, sends a fall report signal to the center side device. The emergency contact address to be contacted when input is received at the emergency contact address transmission reception unit according to the number of times of transmission or the elapsed time since the first fall notification signal was transmitted to the center side device It is only necessary to be configured so as to be changed.

  In order to make it possible to more accurately confirm, for example, whether or not the wearer is aware of the health of the wearer from the reaction to the stimulus of the wearer after reporting the fall, the drive command as in the invention of claim 10. The transmission unit is configured to transmit a drive command signal for driving the stimulus applying mechanism to the terminal device after the time when the fall notification signal is received by the fall notification receiving unit, and the state measurement mechanism The terminal side call mechanism and the video transmission mechanism are acquired by the terminal side microphone, the biological information measured by the biological information measurement sensor before and after the stimulus is given to the wearer by at least the stimulus applying mechanism. What is necessary is just to be comprised so that the audio | voice made and the image | video acquired by the said camera may be transmitted to the said center side apparatus.

  To add the function of the present invention to allow an operator to grasp more detailed information at the time of the fall by the center side device and to select a more appropriate treatment in the existing fall notification system. A fall possibility determination unit configured to determine the possibility that the wearer has fallen based on the amount of movement measured by the movement measurement sensor as in the invention according to claim 11, at least the terminal-side microphone, An on / off control unit that switches an on / off state of the camera, and the on / off control unit at least after the time when the wearer may have fallen is determined by the fall possibility determination unit. A fall notification system program is installed, which is configured to turn on the side microphone and the camera. Bayoi.

  As described above, according to the fall notification system of the present invention, the on / off control unit automatically turns on the terminal-side microphone and the camera from the time when the wearer may fall. Because it is configured, the operator can refer to not only the measurement data but also the voice and video around the wearer after the fall with the center side device, and more accurately grasp the situation of the wearer at the fall be able to. Therefore, the operator can provide rescue arrangements and medical advice according to the state of the wearer at the time of the fall.

<About the overall configuration of the fall notification system 200>
The fall notification system 200 according to the present embodiment automatically reports to the center C when, for example, it is detected that a sick person or an elderly person has fallen, and appropriate relief measures and emergency contact information are sent from the center C. It is for making contact.

  The fall notification system 200 includes a terminal device 100 worn by a wearer E as shown in FIG. 1 and a center side device 101 set in a center C such as a hospital, for example. 100 and the center side device 101 can transmit and receive signals and data to and from each other via a network X such as the Internet or a telephone line.

  The terminal device 100 measures biological information that is considered to indicate the health state of the wearer E and a movement amount that represents the movement of the wearer E itself, and transmits the measurement data to the center device 101 as measurement data. In addition, the terminal device 100 determines that a fall has occurred in the wearer E when the measurement data satisfies a predetermined fall determination criterion and a predetermined time has elapsed since the fall determination criterion is satisfied. The fall notification unit A1 is configured to transmit to the center side device 101 by a fall notification signal.

  When the center side device 101 receives a fall notification signal from the fall notification unit A1 and is received by the fall notification receiving unit A2, the center side device 101 considers that there has been a fall report, and the terminal device 100 before and after the fall. The state of the wearer E is estimated based on the measurement data transmitted from, and the emergency contact is selected from the estimated state. Further, the center side device 101 is configured to be able to provide medical advice from the operator P such as a doctor residing in the center C to the wearer E who has been notified of the fall. In addition, when the fall occurs, the center side device 101 can remotely control at least a part of the functions of the terminal device 100, and the wearer E who has been notified of the fall sees the reaction to the stimulus, It is also possible to take first aid measures remotely.

  Below, the detailed structure of the said terminal device 100 and the said center side apparatus 101 is demonstrated, referring the functional block diagram of FIG. In FIG. 2, dotted lines connecting the blocks indicate information or signal exchange between the blocks.

A processing completion notification unit B1 for notifying to 101, and a.

  Here, the smartphone includes an acceleration sensor 11, an imaging function, an arithmetic device, and the like in addition to the call function. And, it has input / output devices such as memory, CPU, touch panel display, etc., and various functions to be described later are realized by executing the program for realizing the function as the falling notification system 200 stored in the memory. To do.

  The state measurement mechanism 1 acquires a movement measurement sensor that measures a movement amount that is a value related to acceleration, a biological information measurement sensor 12 that measures biological information of the wearer E, and position information of the wearer E. The GPS 13 is a position information acquisition unit, and a measurement data transmission unit 14 that transmits measurement data measured by the terminal device 100 including the amount of movement and the biological information to the center side device 101.

  In the present embodiment, the motion measuring sensor is an acceleration sensor 11 capable of measuring acceleration in three axial directions, and the acceleration sensor 11 is continuously measured in an on state so that the fall of the wearer E can be detected. Note that the amount of motion is not limited to acceleration, but may be velocity, angular acceleration, or the like, which is an integral value of acceleration. Any sensor suitable for measuring these amounts can be used as a motion measurement sensor. can do.

  In the present embodiment, the biological information measurement sensor 12 is a sensor for measuring, for example, the pulse, cardiac current, brain wave, etc. of the wearer E, and is attached to a corresponding part of the wearer E separately from the smartphone. It is. For example, regarding the pulse, the biological information measuring sensor 12 may be configured such that the vein of the wearer E is imaged with the camera 21 attached to the smartphone and measured from the imaging result.

  The measurement data transmission unit 14 is configured to transmit measurement data measured by the acceleration sensor 11 and the biological information measurement sensor 12 to the center side device 101 at predetermined intervals. Note that the biological information measurement sensor 12 is normally in an off state, and is activated when measurement data is transmitted by the measurement data transmission unit 14 and when the wearer E described later may have a slight fall. Then, the biometric information is measured and transmitted to the center side apparatus 101 by turning on.

  The video transmission mechanism 2 includes a camera 21 and a video transmission unit 22 that transmits video data captured by the camera 21 to the center side device 101. The camera 21 is normally in an off state. This is activated when there is a possibility that the wearer E has fallen, and the video transmission unit 22 transmits the video to the center side device 101.

  The terminal-side call mechanism 3 includes a terminal-side microphone 32, a terminal-side speaker 31, and a terminal-side voice transmission / reception unit 33 that transmits and receives voice signals to and from the center-side device 101. In the present embodiment, the terminal-side microphone 32 is also used to collect surrounding sounds when the wearer E falls down in addition to a call. The terminal-side speaker 31 is also used for sounding an alarm sound (a beep sound or a sound for notifying an emergency situation) when the wearer E falls down in addition to a call. Furthermore, this terminal side call mechanism 3 reproduces not only the mechanical guidance voice but also the real voice of the operator P such as a doctor in the center C when the wearer E falls down to the center side device 101. It is like that. When the real voice of the operator P is heard, it is possible to make it difficult to lose consciousness even if the fallen state of the wearer E is bad, and the survival rate of the wearer E can be improved.

  The stimulus applying mechanism 4 includes, for example, a vibrator 41, an electric stimulator 42 for applying an electric stimulus to the wearer E, and a drive command receiving unit 43 that receives a drive command signal from the center side device 101. It is. In the state where the vibrator 41 and the electrical stimulator 42 are overturned by the wearer E and the remote operation of the terminal device 100 by the center side device 101 is permitted, the drive command receiving unit 43 receives the drive command signal. It is made to drive only when it is received. The vibration of the vibrator 41 and the electrical stimulation by the electrical stimulator 42 are applied to the wearer E after the fall, and are used to confirm the reaction. For example, when there is a response due to these stimuli, the wearer E is conscious and relatively safe, but when there is no response, it can be determined that the person is in a dangerous state. This stimulus applying mechanism 4 can be used not only for the purpose of seeing the reaction of the wearer E after the fall, but also for performing an emergency treatment by electrical stimulation remotely from the center C, for example.

  The input receiving unit 5 is an icon displayed on the screen of the touch panel display, and a predetermined command is executed only by the wearer E touching the icon. More specifically, as shown in FIG. 3, the input receiving unit 5 includes an emergency contact transmission receiving unit 51 that can be used after the possibility of the wearer E falling, and the wearer E falling. And the notification cancel accepting unit 52 for canceling the notification when the notification to the center side device 101 is not performed, and the center side device 101 is notified of the fall, and the terminal And an alarm sound cancellation receiving unit 53 for interrupting the state in which the alarm sound is sounded from the side speaker 31. Here, although the input receiving unit 5 is configured as a software switch, for example, the input receiving unit 5 for executing each command may be configured by a mechanical switch.

  As shown in FIG. 2, the control unit 6 is configured to exhibit at least functions as a fall possibility determination unit 61, an on / off control unit 62, and an alarm sound control unit 63.

  The fall possibility determination unit 61 is configured to determine the possibility that the wearer E has fallen in two steps based on the acceleration measured by the acceleration sensor 11. More specifically, the fall possibility determination unit 61 determines that the wearer E has fallen slightly when the absolute value of the amount of change in acceleration measured by the motion measurement sensor exceeds a predetermined value. It is determined that there is a possibility. Further, after the fall possibility determination unit 61 determines that the wearer E has a slight possibility of falling, the acceleration measured by the acceleration sensor 11 is gradually decreasing or the change in acceleration is detected. If there is no, it is determined that there is a possibility that the wearer E has fallen. Here, when the fall possibility determination unit 61 determines that there is a slight possibility that the wearer E has fallen, the acceleration sensor 11 continuously measures, for example, an acceleration of a predetermined value or more. Therefore, it is determined that the wearer E has not fallen but has only been subjected to a large impact on the acceleration sensor 11 for another reason.

  The on / off control unit 62 switches the on / off state of the terminal microphone 32, the camera 21, the biological information measurement sensor 12, and the GPS 13 based on the determination of the possibility of falling by the tipping possibility determining unit 61. is there. More specifically, the on / off control unit 62 keeps the above-described devices in an off state in a normal state where there is no possibility of falling. On the other hand, the on / off control unit 62 is a clue for estimating the place where the center side device 101 has fallen, the surrounding situation, the state of the wearer E, etc. after the time point when it is determined that there is a possibility of the fall. In order to be able to acquire various types of information immediately after a fall occurs, the above-described devices are turned on.

  If the alarm sound control unit 63 determines that the wearer E may have fallen seriously in the fall possibility determination unit 61, the terminal-side speaker 31 may, for example, say “Are you okay? "?" Or the like is played back to the wearer E and the surrounding people. In addition, after the terminal device 100 is notified of the overturn from the center side device 101, the alarm sound control unit 63 uses the terminal side speaker 31 as an alarm sound, for example, “emergency” A warning sound for notifying the people around the occurrence of an emergency is reproduced. The volume of the alarm sound reproduced by the terminal-side speaker 31 by the alarm sound control unit 63 is set to be equal to or higher than a predetermined volume so that a person within a predetermined distance from the terminal device 100 can sufficiently hear it. It is set. For example, the volume of the alarm sound may be set to the maximum volume that can be set as a smartphone.

  In the present embodiment, the fall notification unit A1 determines that there is a possibility that the wearer E has fallen in the fall possibility determination unit 61, and when the predetermined time has passed, A fall notification signal is transmitted to the center side device 101. That is, if the fall possibility determination unit 61 determines that the wearer E may have fallen, the fall report unit A1 does not report the fall to the center side device 101. For example, the wearer When the acceleration sensor 11 has only picked up a large impact when E hits something, a notification of falling is not made.

  The processing completion notification unit B1 transmits a processing completion notification signal to the center side device 101 when there is an input to the notification cancellation reception unit 52 or the warning sound cancellation reception unit 53. is there. On the other hand, when there is no input to the warning sound cancellation receiving unit 53, the fall notification unit A1 repeats the fall notification to the center side device 101 every predetermined time.

<About the configuration of the center side device 101>
The function of the center side device 101 is realized by a so-called computer including, for example, a CPU, a memory, an input / output device, a display device, and the like. That is, the center side device 101 receives at least measurement data transmitted from the terminal device 100 as shown in the functional block diagram of FIG. 2, and displays a variety of information based on the measurement data. The center side call mechanism 8 configured to enable voice communication with the terminal device 100 and the fall notification signal from the fall notification unit A1 are received, and the processing in the data processing unit 7 is started. As the fall notification receiver A2, the drive command transmitter 9 for transmitting a drive command signal to the stimulus applying mechanism 4, and the process completion notification receiver B2 for receiving a process completion notification from the terminal device 100 It demonstrates the function of.

  The data processing unit 7 includes a measurement data receiving unit 71 that receives measurement data of acceleration and biological information from the terminal device 100, and a state in which the wearer E has not fallen. The reference state storage unit 72 that stores the acquired position information as reference data, the reference data stored in the reference state storage unit 72 when the terminal device 100 reports a fall, and the measurement data The fall state determination unit 73 that compares the measurement data received by the reception unit 71 and determines the activity state of the wearer E before and after the fall and the place where the report of the fall was made, and the fall state determination unit 73 creates The fall state data storage unit 74 for storing the fall state data and the emergency for determining the emergency contact address according to the fall state data The contact point determination unit 75, the video reception unit 76 that receives the video transmitted from the terminal device 100, the fall state data, the emergency contact information, and the video received by the video reception unit 76 are displayed on the display device. And a display unit 77 for display.

  The reference state storage unit 72 creates a database of features of the activity state for each place where the wearer E was present based on acceleration, biological information, and position information other than the time of falling periodically transmitted from the terminal device 100. Is what you remember. In this embodiment, based on the position information acquired by the GPS 13 and the position information of the home of the wearer E registered in advance, the reference state storage unit for the characteristics of the activity state for each distance from the home 72 is stored. For example, the acceleration and biological information at the time when the wearer E is resting, walking, and exercising are acquired in advance, and the measurement data newly transmitted from the terminal device 100 is compared with the previously acquired measurement data. The activity state of the wearer E is classified as resting, walking, or exercising, and the reference state storage unit 72 stores the reference data for each distance from the home as reference data.

  The fall state determination unit 73 is the activity state before and after the fall of the wearer E based on the acceleration before and after the report of the fall transmitted from the terminal device 100 and the biological information after the report of the fall. An activity state determination unit 731 that determines whether a fall has occurred, and a fall place determination unit 732 that determines a place where the fall has occurred based on position information after the fall has been reported.

  The fall state determination unit 73 compares the reference data stored in the reference state determination unit with the acceleration measured before and after the fall and the biological information measured after the fall, and the wearer before the fall The activity state of E and the activity state of the wearer E after the fall are determined.

  The fall place determination unit 732 performs not only the absolute position of the fall place from the position information measured by the GPS 13, but also the fall place classification according to the distance from the wearer's E home.

  The state data storage unit 74 at the time of the fall indicates the fall location of the wearer E, the activity state of the wearer E before the fall, and the activity state of the wearer E after the fall determined by the fall state determination unit 73. A set of fall state data is stored. As shown in the example of FIG. 4, the fall state data storage unit 74 stores the fall state data every time there is a fall notification from the terminal device 100, and is built as a database. . Here, there is a case where the biological information measurement sensor 12 is in the off state immediately before the wearer E falls, and the pulse state or the like cannot be measured immediately before the fall, but in this case, for example, in the past You may substitute by using the nearest information at the time of the report of the fall among the biometric information transmitted regularly. In addition, the activity state can be paraphrased as indicating the health state determined comprehensively including the degree of movement of the wearer E and the pulse.

  As described above, the fall-time state data storage unit 74 accumulates the fall-time state data for each report of a fall from the past, so that, for example, the tendency of the place where the fall is likely to occur or the activity state is grasped. Or, when there is a new fall report, the operator P can provide appropriate relief measures by comparing the new fall status data with the fall status data when there has been a previous fall report. It can also be made easier to take.

  The emergency contact determination unit 75 has an emergency contact determination table for determining whether there is a need for a helper or a helper set in advance corresponding to each fall state data as shown in FIG. When there is a notification of a new fall, the emergency state data corresponding to the data is determined by referring to the current fall state data stored in the fall state data storage unit 74 It is.

  The emergency contact determination table is predetermined based on the following criteria, for example. That is, whether or not the helper needs to be dispatched is determined based on the place where the wearer E falls and the distance between the wearer's E and his / her home. Makes it mandatory to call for helpers.

  In addition, the emergency contact determination table determines whether or not a doctor or an ambulance is required to be dispatched based on the activity state before the wearer E falls or the activity state after the wearer E falls. For example, if the activity state before the fall was active, but the activity state after the fall was very low activity, the condition of the wearer E may suddenly change It is stipulated that a doctor or ambulance must be dispatched.

  It should be noted that the criteria for determining emergency contact shown here are examples, and the post-fall status data and emergency contact are linked in various correspondences so that an appropriate emergency contact is selected. Good.

  The emergency contact determination unit 75 is configured to change the emergency contact according to the elapsed time since the fall notification receiver A2 received the fall notification signal.

  As shown in FIG. 6, the display unit 77 has the emergency contact determined by the emergency contact determination unit 75, the state data at the time of the fall when there is a report of the fall, and the fall, as shown in FIG. The time elapsed since receiving the notification is displayed on at least one screen. The display unit 77 is also configured to display a video imaged by the terminal device 100 after the video receiving unit 76 has fallen.

  For example, when the information as shown in FIG. 6 is displayed on the display device, the operator P in the center C is “exercising” and “the pulse is normal” before the wearer E falls. Nevertheless, since the activity state after the fall is “immobility” and “the pulse is unknown”, it can be judged that it is in danger due to a heart attack, etc., and it is immediately dispatched to the doctor as an emergency contact It can be determined that the request should be made. That is, in the present embodiment, the operator P can know information on the activity state and the fall location of the wearer E before and after the fall, and it is possible to accurately estimate the wearer E's state. It is easy to select an emergency contact. Furthermore, the operator P can also check the external situation such as whether there is a person who is likely to help around by referring to the video and audio after the fall transmitted from the terminal device 100, and the state of the wearer E. .

<About the operation of the fall notification system 200>
The operation of the fall notification system 200 configured as described above will be described with reference to the flowcharts of FIGS.

  First, operations from the fall detection to the fall notification in the terminal device 100 will be described with reference to the flowchart of FIG.

  While the wearer E is in a normal state, the terminal device 100 always monitors whether or not the absolute value of the amount of change in acceleration measured by the acceleration sensor 11 that triggers a fall notification exceeds a predetermined value. It operates as a normal monitoring mode.

  That is, when the fall possibility determination unit 61 determines that the wearer E has a slight possibility of falling because the large vibration is detected in the acceleration sensor 11 (step S1), the terminal device 100 is in a detailed state. Transition to monitoring mode. More specifically, the on / off control unit 62 turns on the camera 21, the terminal-side microphone 32, and the GPS 13 and turns on the biological information measurement sensor 12, and sets the monitoring interval (sampling interval) of each sensor normally. The interval is changed to be shorter than that in the monitoring mode (step S2). Note that if the acceleration change amount is not acquired so as to exceed the predetermined value in step S1, the normal monitoring mode is continued.

  Next, the fall possibility determination unit 61 determines whether or not there is a possibility that the wearer E has fallen. That is, if the wearer E's movement weakens or stops within a certain time, the fall possibility determination unit 61 determines that there is a possibility of a severe fall, and enters the notification standby mode into the terminal device. 100 shifts (step S4). Otherwise, the vibration measured by the acceleration sensor 11 is determined as, for example, a vibration in daily life, and the terminal device 100 shifts from the detailed state monitoring mode to the original normal monitoring mode (step S5).

  When the terminal device 100 shifts to the notification standby mode, as shown in FIG. 3, the emergency contact destination transmission reception unit 51 and the notification cancellation reception unit 52 are displayed on the operation screen of the terminal device 100. The remaining time until the notification is actually performed is displayed in a countdown manner (step S6). Further, the alarm sound control unit 63 reproduces a confirmation sound for calling attention to the person around the wearer E, “Are you okay?” From the terminal side speaker 31. At this time, the terminal device 100 itself is also vibrated by the vibrator 41 (step S7). During this time, the countdown indicating the remaining time until the notification displayed on the operation screen decreases with the elapsed time (step S8).

  When there is an input to the notification cancel acceptance unit 52, the terminal device 100 is released from the notification standby mode and shifts to the normal monitoring mode (step S9). If not, it is further determined whether or not the standby time until automatic notification has passed (step S10). While the waiting time has not yet elapsed, the operations of steps S7 to S10 are repeated. When there is no input in the notification cancellation receiving unit 52 and the countdown is completed after a waiting time has elapsed, the falling notification unit A1 outputs a falling notification signal to the center side device 101. When this fall notification signal is output, the terminal device 100 shifts to a post-report mode that accepts remote operation from the center side device 101 (step S11).

  When the terminal device 100 shifts to the post-notification mode, the alarm sound control unit 63 causes the terminal-side speaker 31 to reproduce a warning sound such as “Emergency”, and the operation screen accepts the emergency contact information transmission. The unit 51 and the warning sound cancellation receiving unit 53 are displayed (step S12).

  Further, the measurement data transmission unit 14 transmits acceleration, biological information, and position information measured before and after the fall to the center side device 101, and the video transmission unit 22 is also transmitted to the camera 21 by the on / off control unit 62. The video after the activation is transmitted to the center side device 101 (step S13). As long as there is no input in the alarm sound cancellation receiving unit 53 (step S14), the fall notification to the center side device 101 is repeated by the fall notification unit A1 every predetermined time (step S15). When there is an input to the alarm sound cancellation receiving unit 53, the terminal device 100 shifts from the post-report mode to the normal monitoring mode, and the processing completion notification unit B1 performs processing to the center side device 101. A completion notification signal is transmitted (step S16).

  As described above, the terminal device 100 performs operations from the detection of the fall to the notification to the center side device 101. As shown in step S2, a large vibration is detected in the terminal device 100, and the on / off control unit 62 activates the various sensors, the camera 21, and the microphone from the time when the wearer E falls down. It is possible to cause the terminal device 100 to collect various types of information that can be used to reliably determine the situation of the wearer E from the time when the fall occurred. As a result, the operator P in the center C can correctly guess the situation of the wearer E, and the rescue measures and emergency contact information can be set appropriately.

  Next, of the operations when the center side device 101 is notified of the overturn, the operation that acts on the terminal device 100 from the center side device 101 will be described with reference to the flowchart of FIG.

  When the center side device 101 receives the fall notification signal from the terminal device 100 at the fall notification receiving unit A2, the data processing unit 7 displays the measurement data and video transmitted from the terminal that has received the notification. While being displayed on the display device, the sound collected by the terminal-side microphone 32 is also reproduced. That is, the data processing unit 7 displays information obtained from the terminal device 100 of the wearer E who has fallen on the display device. At this time, the data processing unit 7 also displays the fall location, the movement trajectory until just before the fall, information related to the previous fall report, post-fall status data and emergency contact information as shown in FIG. (Step ST1).

  Next, in order to confirm the state of the wearer E after the fall, the operator P in the center C transmits a drive command signal from the drive command transmission unit 9 to the terminal device 100, and the vibrator 41 of the terminal device 100. Then, the stimulator 42 is driven to stimulate the wearer E. By observing the reaction of the wearer E before and after applying the stimulus based on measurement data including video, audio, and biological information transmitted from the terminal device 100, the operator P relates to the state of the wearer E after the fall. More detailed information can be obtained. Further, the voice of the operator P is transmitted to the terminal device 100 using the center side call mechanism 8, and for example, until the wearer E provides medical advice on a coping method to be taken or a rescue arrives. Then, the wearer E is peeled off by the real voice (step ST2).

  While the processing completion notification is not received by the processing completion notification receiving unit B2 (step ST3), the emergency contact determined by the emergency contact determination unit 75 is notified according to the elapsed time from the first fall notification. Continued by the operator P (step ST4).

  When the processing completion notification receiving unit B2 receives the processing completion notification from the terminal device 100, the center side device 101 instructs the terminal device 100 to return the state monitoring to the normal monitoring mode (step ST5). And the operation | movement in the center side apparatus 101 at the time of fall occurrence is complete | finished.

  Next, operations relating to updating of the database related to the state data after the fall, determination of emergency contact information, etc. in the data processing unit 7 will be described with reference to the flowchart of FIG.

  When there is a new fall notification from the terminal device 100 (step SE1), the center side device 101 updates the fall state data stored in the fall state data storage unit 74 (step SE2). .

  Then, the data processing unit 7 updates the unprocessed elapsed time according to the elapsed time from the time when the falling report is made, and displays the unprocessed elapsed time on the display device (step SE3).

  Next, the emergency contact determination unit 75 determines a corresponding emergency contact by referring to the emergency contact determination table as shown in FIG. 4 based on the fall state data obtained by the current fall notification. Then, the display unit 77 displays the determined emergency contact address on the display device (step SE4).

  While the processing completion notification is not received by the processing completion notification receiving unit B2 (step SE5), the operations of steps SE1 to SE4 are repeated, and the processing completion notification receiving unit B2 sends the processing completion notification to the processing completion notification. When receiving from the terminal device 100, the center side device 101 instructs the terminal device 100 to return the state monitoring to the normal monitoring mode (step SE6). And the operation | movement in the center side apparatus 101 at the time of fall occurrence is complete | finished.
