[Operation Embodiment of Determining / Predicting Stroke by Using Biosignal]

3 is a flowchart illustrating the operation of the stroke determining unit 300 of the present invention to determine or predict the occurrence of a stroke through a signal measured by the biosignal measuring unit 100.

As shown in FIG. 3, the stroke determining unit 300 sets the reference range of the biosignal after receiving the driver's health information stored in the database 400 and the stroke history stored in the stroke history storing unit 600. . 3 illustrates setting a reference range of blood pressure as one example of various types of bio signals used / measured in the present invention. The stroke determining unit 300 may store the health information and the stroke history storage received from the database 400. On the basis of the driver's stroke history received from 600, Min, the lower limit of the reference range of the driver's blood pressure, and Max, the upper limit, are set.

The way in which the stroke determining unit 300 utilizes the health information previously stored in the database 400 is an average of the range of the bio signals when the driver is in a normal state through the medical examination history or the measured bio signals included in the health information. It may be determined as the recommended bio-signal range of the parking physician who is in charge of the examination or the health examination information.

After setting the reference range, the stroke determining unit 300 receives the bio signal measured in real time from the bio signal measuring unit 100, that is, the current blood pressure, and determines whether the blood pressure measured in real time is included in the reference range. To judge. When the blood pressure measured in real time in the bio-signal measuring unit 100 is out of the reference range, the stroke determination unit 300 determines that a stroke has occurred to the driver, and operates the notification unit 500 to stroke the history of stroke occurrence. The history of stroke occurrence is stored in the history storage unit 600.

In order to predict the stroke occurrence of the driver in the stroke determination unit 300, the reference range may be sequentially narrowed as shown in FIG. 3.

Referring to FIG. 3, the stroke determination unit 300 reduces the reference range to an initial level of 90% when the blood pressure of the driver measured in real time by the biosignal measuring unit 100 is included in the reference range. Then, it may be determined whether the measured blood pressure is included in the range reduced to 90% level, and it may be determined that stroke occurrence is predicted when the measured blood pressure is out of the range reduced to 90% level of mood range. When the stroke occurrence is predicted, the stroke determination unit 300 may operate the notification unit 500 and store the stroke occurrence prediction history in the stroke history storage unit 600. The operation of the notification unit 500 may be in the form of outputting a warning sound or transmitting a predetermined message to a designated place.

In the operation embodiment as described above, the stroke determination unit 300 may predict the occurrence of the stroke of the driver to the reference range reduced to a certain level while sequentially reducing the reference range such as 90%, 80%.

In the case of the notification unit 500, when the driver's blood pressure measured in real time by the biosignal measurement unit 100 is not included in each of 100%, 90%, and 80% of the reference range, different warning sounds or messages may be provided. You can print For example, the notification unit 500 may output a warning sound or an emergency message that the first emergency treatment is needed, such as "emergency" when exceeding 100% of the reference range of the first stage, and the measured blood pressure is in the reference range. If more than 90% and less than 100% of the warning message such as "danger" can be output to the warning message, if the measured blood pressure is more than 80% or more than 90% of the standard range, the warning sound such as "caution" Or you can print a message. However, the biosignal of the driver may be output at the same time to the output warning sound or message.

100%, 90%, 80% of the reference range as described above is one example, there may be a variety of ranges, in addition to blood pressure can be applied to a variety of bio-signals measured in the bio-signal measuring unit.

In the case of the notification sound output from the notification unit 500, an appropriate first aid method may be output together with each step. For example, when the driver's status is "emergency", the method of the CPR may be output along with the "emergency" notification sound so that people around him may perform first aid such as CPR. In addition, the strength of the notification sound output from the notification unit 500 may be differentially output according to the state of the driver. For example, the output value of "attention" may be 60% of the maximum output value of the notification sound output from the notification unit 500, and may be 80% for "danger" and 100% for "emergency". .

When the notification unit 500 transmits the driver's location to the guardian, the family, or the emergency medical center, the driver's location may be transmitted together, and the bio signal measuring unit 100 or the operation information measuring unit worn by the driver for this purpose. 600 may further include means such as a GPS to locate the driver.

[Operation Embodiment for Determining Whether or Not a Stroke Occurs Using Operation Information]

4 is a flowchart illustrating a process in which the stroke determining unit 300 of the present invention predicts the occurrence and occurrence of a stroke of a driving driver based on the driver's motion information measured by the motion information measuring unit 200.

The motion information measuring unit 200 used in FIG. 4 transmits the captured image data to the stroke determining unit 300 to the photographing unit 210 illustrated in FIG. 2.

First, the stroke determination unit 300 determines whether the normal position region is set. If the normal position region is not set, the stroke determination unit 300 overlaps the region where the driver is located among the image data received from the photographing unit 210 for a predetermined time. Set the normal position area. During the setting of the normal position area, the driver does not have a stroke, and if possible, sets the normal position area in a straight state. Obtaining an area where the driver is located may be implemented by an image processing method that is variously studied.

A device having a program corresponding to the stroke determining unit 300 may be provided with a separate input / output means, so that the driver may set a normal position area when desired.

After setting the normal position region, the stroke determination unit 300 calculates the overlap rate x between the region where the driver is located and the normal position region among the image data photographed by the photographing unit 210. The overlap rate x indicates how many pixels are included in the normal position area among the pixels forming the area where the driver is located among the image data input in real time.The higher the overlap rate x, the driver operates in the normal state. You can judge that there is. However, since there may be a left turn or a right turn depending on the road situation, the overlap rate x may be a case where the overlap rate x is continued or lowered for a predetermined time until the stroke determining unit 300 determines whether the stroke is generated.

As shown in FIG. 4, the stroke determining unit 300 determines that the overlap state x is 90% or more and 100% or less, and determines that it is a normal state. It can output a caution warning sound or a message, and if more than 70% 80% or less as a danger, 70% or less is determined to be an emergency to operate the notification unit 500, after the stroke history storage unit 600 ) The stroke incidence / prediction history. When the alarm unit 500 outputs an emergency warning sound or a message, the controller may decelerate the vehicle at a constant speed and flash the emergency light to notify the surroundings of the current situation.

Whether the stroke is determined using the photographing unit 210 of the motion information measuring unit 200 shown in FIG. 4 is just one example. In addition, the stroke information may be determined in various ways using the motion information measuring unit 200. The occurrence can be predicted. For example, among the eyeballs of the driver photographed through the photographing unit 210, the proportion occupied by the black man is calculated in real time, and when the proportion occupied by the black man becomes less than the reference value for a predetermined time, it is determined that a stroke has occurred. The occurrence may be predicted, and in addition, there may be an exemplary embodiment in which the notification unit 500 operates when the direction of the driver's face / eye is not matched with the driving direction of the vehicle for a predetermined time.

As another example of determining whether a stroke is generated based on the driver's motion information measured by the motion information measuring unit 200, there may be a case where the vibration measured by the motion information measuring unit 200 including the vibration sensor is used. . The vibration sensor is used to determine the epilepsy phenomenon of the driver. In general, when a stroke occurs in the patient, the epilepsy, which causes cramps in the driver's body, is accompanied. Therefore, the vibration sensor may measure the vibration due to epilepsy when the stroke is generated to the driver in addition to the vibration generated during driving in general, and transmit it to the stroke determination unit 300. Since the vibration generated by epilepsy, or convulsion, has a different characteristic from the vibration generated by driving of the vehicle, the stroke determining unit 300 may have a vibration different from the vibration measured by the driver in a normal state (vibration having a different period or amplitude). ), It can be determined that a stroke has occurred to the user, and in addition, the stroke determination unit 300 has a constant foot pressure of a certain intensity or more in the foot pressure sensor installed in the user's shoes while acquiring driving information of the vehicle together. If it is detected over time, but it is determined that the corresponding foot pressure is not related to the driving of the vehicle (when the foot pressure is detected for a predetermined time in a state other than the acceleration or the sharp deceleration), it may be determined that the user has a stroke.

In the above-described operating embodiments, a method of determining whether a stroke is generated or predicting a stroke is determined in detail by separately determining each of the biosignal and the driver's motion information, but the present invention is not limited thereto. The method and the method using the operation information are mixed, and can be used to compensate for each disadvantage and make use of the advantage.

The stroke monitoring system while driving according to the present invention has been described above to be applied to one driver. However, the stroke monitoring system according to the present invention is not only applied to a driver, but also the information stored in the database of the individual driver 400 can be gathered to form a higher database, the central government, local governments or enterprises to utilize or based on this stroke Enforce related policies or manage the health of stroke patients.

The present invention is not limited to the above-described embodiments, and the scope of application is not limited, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
