Description

  The present invention relates to a technique for controlling the operation of a drive device that exists independently of a biosensor based on sensor data acquired by a biosensor worn by a moving user.

  Techniques for predicting the state of a living body using biological information and changing the environment using this have been widely developed. In these technologies, biological information is acquired using a biological sensor such as a heart rate sensor and a body temperature sensor, and the physical or psychological state of the living body is grasped based on the difference between the sensor data string pattern and the normal state. The (Non-Patent Document 1).

  In such a system, a control device that not only outputs and records the state of the living body predicted from the sensor data string but also operates some actuator (driving unit) when an abnormality is detected in the living body is more useful. That is, abnormality determination is performed according to a standard defined in advance from a sensor data string obtained from the sensor, and as a result of the abnormality determination, the actuator operates according to the standard defined. In order to realize this, it is necessary to associate in advance a device (hereinafter referred to as a drive control device) that acquires data from the sensor, analyzes the sensor data string, and finally controls the operation of the actuator.

  Although changes in the biosensor data associated with changes in the physical condition of a living body (hereinafter referred to as “subject”) from which the biosensor obtains data have a general tendency (Non-Patent Document 1), there are individual differences in the values. There is.

  Therefore, it can be easily imagined that it is necessary to use a personal profile for abnormality determination and actuator activation according to biosensor data. However, in the system that activates the actuator based on the acquired sensor data string, the sensor and the actuator are fixedly connected, and the actuator activation reference is uniformly defined for the sensor data string.

  When multiple users use a system that determines an abnormality according to biosensor data and activates an actuator, if the standard for actuator activation for sensor data is determined uniformly regardless of the target person, the biosensor data pattern varies depending on the individual. I can not cope.

  Furthermore, when the biosensors possessed by each subject are used in such a system, the biosensor data pattern obtained differs depending on the type of biosensor. For example, there are differences in sensitivity, frequency, detection conditions, etc. depending on the manufacturer and model of the biosensor, so even a specific type of biosensor (for example, a heart rate sensor) has a unified actuator activation standard for sensor data. It is also not appropriate to provide

  As an example, consider driving a car that is managed by an operator and may be used by multiple drivers. When there is a driving device that activates an actuator such as an automatic brake or alarm device when a driver's abnormality is determined for biosensor data targeted at the driver, it is unified for any driver If the driver is determined to be abnormal based on the criteria set forth in (2), if the driver has a non-standard biosensor data pattern, the automatic brake will operate in spite of the normal state of mind and body, or It can be overlooked when it is in an abnormal state of mind.

  Therefore, a driving device is considered in which the biosensor is not combined with the actuator in advance, and the abnormality criterion is changed by the subject. At this time, the biosensor is mainly attached to the subject in advance, and it is assumed that the biosensor data of the subject can always be acquired. Further, it is assumed that the abnormality determination criterion for the subject is stored as a profile.

  In this case, although it is possible to determine the state of the subject, it is not possible to activate the actuator installed independently of the sensor according to the state of the subject. A drive device having a mechanism for linking the actuators is required.

  Furthermore, it is necessary to consider that in order to detect an abnormality from sensor data and activate an actuator, the sensor, the sensor data analyzer, the profile, the actuator activation device, and the actuator must operate together. It is. For example, when analyzing the sensor data, if the profile is inquired of a remote server each time, the actuator may not be activated if the profile cannot be read. Therefore, a mechanism that does not require communication with the outside is necessary for the minimum part that reads the sensor data and operates the actuator.

  In view of the above circumstances, the present invention detects an abnormality of a target person using a personal biosensor not registered in advance with a drive unit, and controls the operation of a drive unit of a system shared by a plurality of people. Is an issue.

  Therefore, the present invention links the biosensor and a drive unit independent of the sensor, detects an abnormality of the user who is the target of the biosensor, and detects the abnormality of the drive unit provided to the user. Control the behavior.

  An aspect of the device of the present invention is a drive control device that controls the operation of a drive unit provided to a user based on data detected by a biosensor attached to the user. A biometric sensor attached to the user from the profile server that holds the profile information of the unit and a registration unit that acquires profile information of the drive unit provided to the user and stores the profile information in the profile storage unit; and A biological state detection unit that determines a biological state of the user based on a comparison between data detected by an attached biological sensor and profile information of the biological sensor stored in the profile storage unit; A drive unit that is activated based on the biological state; and an operation determination unit that determines the operation content of the drive unit.

  An aspect as a method of the present invention is a drive control method in which a computer controls operation of a drive unit provided to a user based on data detected by a biosensor attached to the user. And a registration step of acquiring the biometric sensor attached to the user from the profile server holding the profile information of the drive unit and the profile information of the drive unit provided to the user and storing the profile information in the profile storage unit, and the use A biological state detection step for determining the biological state of the user based on collation between data detected by a biological sensor attached to the person and profile information of the biological sensor stored in the profile storage unit; A drive unit that is activated based on the biological state and an operation determination step that determines the operation content of the drive unit. .

  Note that the present invention may be in the form of a program that causes a computer to function as each unit of the apparatus or a program that causes a computer to execute each step of the method.

[Overview]
The drive control system 1 illustrated in FIG. 1 registers profile information of the biosensor 6 attached to the user in advance, and is provided to the user based on the sensor data acquired from the biosensor 6. The activation of the driving unit 7 is controlled. In this control, the profile of the user of the biometric sensor 6 is acquired from the profile server or the user's portable terminal and used. Thereby, different abnormality determinations and activation of the drive unit 7 are possible for each user. Then, the abnormality determination result based on the sensor data from the biosensor 6 is transmitted to the recording server 9.

[Device configuration example]

  Communication between the biological state detection unit 3 and the operation determination unit 4 and the profile storage unit 5 and between the operation determination unit 4 and the profile storage unit 5 and the drive unit 7 are always possible. In addition, communication between the biological state detection unit 3 and the biological sensor 6 is always possible after the biological sensor 6 is registered in the biological state detection unit 3. Therefore, stable communication with a low delay is always ensured between these functional units.

  Further, even when the recording server 9 does not exist as in the drive control system 1 illustrated in FIG. 2, the biosensor 6 worn by the user is registered in advance, and the data of the biosensor 6 is stored. Based on this, it is possible to determine the abnormality of the user and activate the drive unit 7.

  A specific configuration example of each functional unit will be described below.

[Configuration example of each functional unit]
The registration unit 2 illustrated in FIG. 3 acquires information on the biosensor 6 and registers it in the system, and acquires and registers profile information corresponding to the biosensor 6.

  In order to register the sensor information, the registration unit 2 communicates with the biosensor 6 to acquire the sensor information of the biosensor 6, the sensor information storage unit 22 that stores the sensor information, and the sensor information A sensor registration unit 23 that transmits the sensor information to the biological state detection unit 3, a profile acquisition unit 24 that acquires the profile of the biological sensor 6 by communicating with the profile server 8, and a profile that registers the profile in the profile storage unit 22. A registration unit 25 and a registration control unit 26 that controls the functional units 21 to 25 are provided. The registration control unit 26 forms a user interface and can accept an operation from a user.

  As a specific mode of the registration unit 2, when it is included in the same physical configuration as another processing unit (for example, the fixed type of the first embodiment in FIG. 6), it has a different physical configuration from the other processing unit. The mode of being included (for example, the portable terminal type of Example 3 of FIG. 10) is illustrated.

  The biological state detection unit 3 illustrated in FIG. 4 communicates with the biological sensor 6 to acquire sensor data, and determines the biological state based on the acquired sensor data.

  The biological state detection unit 3 includes a registration control unit 31 that registers sensor information transmitted from the registration unit 2, a sensor communication unit 32 that communicates with the sensor, and a sensor information storage unit 33 that stores sensor information to be acquired. A data conversion unit 34 that converts the obtained sensor data string into a format that can be collated with the profile of the biosensor 6, and a collation unit that collates the converted sensor data with the profile of the biosensor 6 read from the profile storage unit 5. 35 and a biological state information transmission unit 36 that transmits the determination result of the biological state based on the collation to the operation determination unit 4.

  The operation determination unit 4 illustrated in FIG. 5 selects the driving unit 7 to be driven and the operation content based on the biological state information detected and transmitted by the biological information detection unit 3 and activates the driving unit 7. The operation record is transmitted to the recording server 9.

  The motion determination unit 4 includes a biological state information receiving unit 41 that receives biological state information from the biological state detecting unit 3, biological state information provided from the biological state information receiving unit 41, and a profile read from the profile storage unit 5. The drive unit 7 that is activated by collating, the operation determination unit 42 that determines the operation content, the actuator activation unit 43 that transmits a signal for operating the drive unit 7, and the detection of an abnormality when an abnormality is detected by the verification Is transmitted to the recording server 9.

  The profile storage unit 5 is a database for storing profile information. The stored profiles include a sensor profile that describes the characteristics of the sensor data acquisition target of the biosensor 6 and an actuator profile that describes the characteristics of a controllable actuator (drive unit).

  The sensor profile includes a general sensor profile that is uniformly set for each sensor type, and an individual sensor profile that is set for each model or individual sensor unit.

  The profile stored in the profile storage unit 5 needs to be readable at all times while using the data of the biosensor 6 of the subject being registered. Further, after the use of the target person (user) is ended, the data is saved in consideration of being discarded or used again after the next time.

  The biosensor 6 is a sensor that can move independently of a system that uses sensor data, a sensor body attached to the user, a communication unit for communicating with one or more external device systems, and this communication A communication control unit for controlling the unit.

  The sensor data of the biosensor 6 is broadcast in a simple implementation. Alternatively, a specific biological state detection unit 3 is registered in advance, and sensor data is transmitted only to the registered biological state detection unit 3. In transmitting the sensor data, the sensor ID is transmitted at the same time.

  The drive unit 7 is an independent device that reads an instruction transmitted from the actuator activation unit 43 of the operation determination unit 4 and actually performs an operation.

  The profile server 8 is a server that returns a sensor profile (profile of the biosensor 6) and an actuator profile (profile of the drive unit 7) to the registration unit 2 in response to an inquiry. The profile server 8 is accessed via a network or placed on the same physical machine as the registration unit 2.

  The recording server 9 is a server having a database for recording an abnormality, and acquires the abnormality information transmitted from the operation determination unit 4 and records it in the database.

  The registration unit 2, the biological state detection unit 3, and the operation determination unit 4 are each realized by hardware resources of a computer. That is, the function units 2 to 4 include hardware resources related to the computer such as at least an arithmetic device (CPU), a storage device (memory, a hard disk device, etc.), a communication interface, and the like. Then, the function units 2 to 4 are implemented by cooperation of these hardware resources with software resources (OS, applications, etc.). The function units 2 to 4 may be configured from a single computer or a plurality of computers.

  A specific embodiment of the drive control system 1 will be described below.

[Specific Embodiment Examples]
(Embodiment 1) In-vehicle terminal The in-vehicle terminal 11 illustrated in FIG. 6 includes functional units 2 to 4 and 5 and 7 surrounded by a dotted line in FIG. The in-vehicle terminal 11 is applied to a system for operating the in-vehicle actuator, and the user can access the registration unit 2 via the user interface of the in-vehicle terminal 11. Hereinafter, this communication format is referred to as a fixed type.

  An operation example of the in-vehicle terminal 11 will be described with reference to the sequence of FIG.

  A technique for enabling communication between arbitrary terminals is out of the scope of this embodiment. In order to enable communication between arbitrary terminals, for example, pairing using a wireless protocol represented by Bluetooth (registered trademark) can be used.

  S101: The registration unit 2 enables communication with the biosensor 6 by pairing or the like by an operation from the user interface.

  S102: The registration unit 2 sends the user ID, system ID, and sensor ID of the user corresponding to the biometric sensor 6 to the profile server 8 to inquire about the profile corresponding to the ID.

  S103: Upon receiving the inquiry, the profile server 8 transmits a profile corresponding to the ID to the registration unit 2.

  S104: The registration unit 2 registers the acquired profile in the profile storage unit 5.

  S105: The registration unit 2 registers sensor information (sensor ID) of the biosensor 6 in the biometric state detection unit 3 so that the biometric state detection unit 3 can use the profile.

  S106: Since the registration unit 2 can communicate with the biological sensor 6, the biological state detection unit 3 processes the sensor data received directly from the biological sensor 6.

(Embodiment 2) Terminal in which biological state detection unit 3 directly communicates with biological sensor 6 The terminal 12 illustrated in FIG. 8 is different from the registration unit 2 in that the biological state detection unit 3 directly communicates with the biological sensor 6. Is the same mode as the in-vehicle terminal 11 of the first embodiment.

  An operation example of the terminal 12 will be described with reference to the sequence of FIG.

  S201: The biological state detection unit 3 enables communication with the biological sensor 6 by pairing, and starts communication with the biological sensor 6.

  S202: The biological state detection unit 3 reads the sensor ID and the sensor data transmitted from the biological sensor 6, and registers that the biological sensor 6 is unknown when it is determined that the sensor ID is not stored in the profile storage unit 5. Queries the part 2 for the profile.

  S203: Upon receipt of the profile inquiry, the registration unit 2 transmits a user ID, a system ID, and a sensor ID to the profile server 8.

  S204: A profile corresponding to the ID is acquired from the profile server 8.

  S205: The registration unit 2 registers the acquired profile in the profile storage unit 5.

  S206: The registration unit 2 registers the sensor information (sensor ID) of the biological sensor 6 in the biological state detection unit 3.

  S207: The biological state detection unit 3 acquires sensor data from the biological sensor 6 and processes it.

(Embodiment 3) System in which registration unit 2 and biological state detection unit 3 are included in separate devices The drive control system illustrated in FIG. 10 includes a registration unit 2 in a user's portable terminal 13 while a biological unit. The state detection unit 3, the operation determination unit 4, the profile storage unit 5, and the drive unit 7 are included in a physical device 14 that is separate from the mobile terminal 13.

  An operation example of the drive control system of this aspect will be described with reference to the sequence of FIG.

  S301: Prior to registration of the biosensor 6, the user registers the biosensor 6 in the registration unit 2 of the user's mobile terminal 13 in advance. As a registration method, input of ID, pairing using a wireless protocol represented by Bluetooth, and the like are possible.

  S302: The user establishes communication between the registration unit 2 of the mobile terminal 13 and the biological state detection unit 3 of the physical device 14. The communication between the functional units 2 and 3 can use a normal wireless protocol.

  S303: The mobile terminal 13 may store a sensor profile in advance. In this case, the registration unit 2 can transmit the sensor profile to the profile storage unit 5 of the physical device 14 without making an inquiry to the profile server 8.

  S306: The biological state detection unit 3 acquires sensor data from the biological sensor 6 and processes it.

(Embodiment 4) A specific example of data transmission from the biosensor 6 As a simple example of data transmission from the biosensor 6, for example, in the drive control system 1 of FIG. A mode in which sensor data is broadcast without designating a destination can be mentioned.

  The biological state detection unit 3 processes the sensor data string received from the biological sensor 6 as sensor data of the biological sensor 6 if the ID of the biological sensor 6 assigned to the sensor data is registered.

  Moreover, as another aspect of data transmission from the biosensor 6, there is an aspect in which the biosensor 6 unicasts sensor data in the drive control system 1 of FIG.

  For example, the biological sensor 6 is paired in advance with the biological state detection unit 3 that is a specific functional unit. For example, Bluetooth is used for pairing. The paired biological sensor 6 transmits sensor data only to the specific biological state detection unit 3. The biological state detection unit 3 receives sensor data from a specific biological sensor 6 and processes it as sensor data from the biological sensor 6. At this time, the sensor data string may be identified by the ID of the biosensor 6 or the biosensor 6 may be identified by fixing a communication channel to the specific biosensor 6.

(Embodiment 5) Specific Aspect Example of Data Transmission to Recording Server 9 In Embodiments 1 to 4, when it is determined as abnormal based on the data of the biosensor 6, an actuator (not shown) by the drive unit 7 ( And the abnormality information is transmitted to the recording server 9. The transmitted abnormality information includes a set of four of an occurrence time, a user ID, a system ID, and a code representing an abnormality type.

  If no abnormality has occurred, the normality may be periodically transmitted to the recording server 9. In this case, the occurrence time, the user ID, the system ID, and the abnormality type are transmitted in the same manner, but a code indicating “normal” is used as the abnormality type.

  The recording server 9 does not need to exist remotely and may be installed in the apparatus system. In this case, when an abnormality occurs, the abnormality information is immediately recorded, and when the user ends the use of the apparatus system, the abnormality information recorded in the recording server 9 is recorded on a removable information medium, or Sent to an external server via a temporary network.

  Moreover, the structure which does not use the recording server 9 is also possible. In this case, the operation is completed from the biometric information reading by the biometric sensor 6 to the activation of the drive unit 7, and the subsequent recording is not saved. A configuration example in this case is, for example, an aspect of the drive control system 1 shown in FIG.

(Embodiment 6) An automatic brake system to which the drive control system of Embodiment 3 is applied An aspect of an automatic brake system for an automobile to which the drive control system of Embodiment 3 is applied will be described below. As the biosensor 6 of this system, a biosensor for acquiring driver's biometric information is applied, and acceleration, driver's heartbeat, and temperature can be acquired.

  An example of a sensor profile related to the driver's biological information is shown in Table 1. In this example, when a heart rate exceeding the upper limit value, a heart rate falling below the lower limit value, or sleep is determined, if it lasts longer than the time specified by the duration, it is determined to be abnormal. The sensor profile can be prepared individually for individuals, or a general-purpose profile that can be used for the same sensor.

  Consider the case where a car is shared by multiple drivers. In the drive control system of FIG. 10, the mobile terminal 13 is applied to the driver's mobile terminal, and the physical device 14 is applied to the vehicle-mounted device.

  The biosensor 6 worn by the driver is paired with the mobile terminal 13 in advance. The driver accesses the vehicle-mounted device of the automobile from the portable terminal 13 and starts communication. Thereafter, the sensor profile is stored in the profile storage unit 5 of the vehicle-mounted device according to the sequence of FIG. Data transmission to the unit 3 is started.

  An example of a sensor data sequence is shown in Table 2 below. Here, time is a relative time from the start time, RRI is a heartbeat interval obtained by a heartbeat sensor, temperature is a body surface temperature, and accelerations X, Y, and Z are accelerations obtained by a triaxial acceleration sensor. In addition to this data string, the sensor ID is also sent at the same time.

  When reading the sensor data string, the biological state detection unit 3 first converts the sensor data so that it can be collated with the sensor profile. For conversion, a function corresponding to each data type is used.

  Moreover, the biological state detection part 3 can perform sleep determination by defining the function regarding sleep appropriately. For example, according to Non-Patent Document 2, classification can be made into three classes of awakening, REM sleep, and non-REM sleep using heartbeat data. The biological state is determined by sleep determination using these methods.

  The converted sensor data is compared with the sensor profile by the collation unit 35 of the biological state detection unit 3. This is determined as abnormal when the converted sensor data matches the abnormality determination condition of the sensor profile.

  When the abnormality is determined, the biological state information including the abnormality type is transmitted from the biological state detection unit 3 to the operation determination unit 4.

  The operation determination unit 4 reads the actuator profile from the profile storage unit 5 in advance. The actuator profile specifies an actuator type, an operable range, and a start condition. In addition, an actuator to be activated for each subject can be specified in the user profile.

  An operation example of each functional unit of the operation determination unit 4 will be described below with reference to FIG.

  When the biological state information receiving unit 41 reads the biological state information, the operation determining unit 42 determines the actuator to be activated and the operation content thereof according to the actuator profile and / or the user profile.

  When the actuator and its operation content are determined, the actuator activation unit 43 transmits the operation content to the drive unit 7 of the selected actuator. The operation content includes, for example, “applying a sudden brake” and “ringing the alarm device at the maximum volume”.

  In parallel with the above processing, the abnormality information transmitting unit 44 transmits information indicating that an abnormality has been determined to the remote recording server 9. The driver ID, sensor type, sensor, and abnormality type are transmitted to the recording server 9.

(Embodiment 7) A mode in which the present invention is linked with a personal biosensor and a vehicle-mounted sensor A sensor such as a speedometer and an engine tachometer is attached to a vehicle, and the state of the vehicle can be acquired by connecting to a computer. Is possible. The driver's stress state changes depending on the vehicle running state such as the vehicle speed, acceleration, and curve (Non-Patent Document 3). For this reason, only the measurement of the biological state of the driver by the biological sensor is insufficient as a material for determining whether it is within the normal range during driving or should be regarded as abnormal.

  Therefore, for example, in the drive control system 1 of FIGS. 1 and 2, the profile storage unit 5 stores in advance the profile of the abnormal state of the biological state according to the vehicle running state. Then, in consideration of the state of the vehicle acquired from the vehicle-mounted sensor attached to the vehicle and the biological state acquired by the driver's biological sensor 6, more accurate detection of the biological state of the driver and the drive device Perform motion judgment.

  An operation example of the living body state detection unit 4 of the drive control system 1 in consideration of the living body state and the vehicle traveling state will be described with reference to FIG.

  S1: It is determined whether there is an abnormality in the biological state from the biological sensor 6 and the sensor profile.

  S2: If it is determined that there is an abnormality in the living body state, the vehicle sensor reading device 15 outside the drive control system 1 is accessed and the current vehicle running state is read.

  S3: The abnormal range of the biological state according to the vehicle running state is read from the profile storage unit 5.

  S4: It is determined whether or not the biological state is in an allowable range. As a result, when it is determined that there is an abnormality, a command for operating the drive unit 7 according to the profile is issued. Thereby, the abnormality determination combining the vehicle running state and the biological information becomes possible.

  An example of a determination method based on the relationship between the vehicle speed and the heart rate in S4 will be described. When an abnormality is determined based only on the heart rate according to the vehicle speed, which is an example of the vehicle running state, the human heart rate naturally increases as the vehicle speed increases, so the upper limit of the heart rate that should be determined as abnormal also increases. I think that. Therefore, the threshold value θ used for abnormality determination can be determined based on, for example, the graph of FIG.

  S5: The abnormal state is transmitted to the operation determination unit 4.

  In the above S1 to S5, the order of S2 and S3 may be reversed. In this case, the living body state detection unit 3 preliminarily designates an allowable amount of the living body state according to the state of the vehicle sensor 6, and determines that the living body is abnormal when the value is exceeded.

[Effect of this embodiment]
According to the above drive control system 1, it is possible to detect an abnormality of a target person using an actuator and a personal biosensor not registered in advance, and to activate an actuator of a system shared by a plurality of persons.

  In particular, profile information of the biosensor 6 is registered in advance, and the operation of the drive unit 7 is controlled based on sensor data acquired from the biosensor 6. Further, since the profile of the user of the biosensor 6 can be acquired and used from the profile server or the mobile terminal of the user, abnormality determination and activation of the drive unit 7 that are different for each user can be performed. Furthermore, since the abnormality determination result based on the sensor data from the biosensor 6 is transmitted to the recording server 9, it can be used for labor management and the like.
