Description

[0001] The present invention relates to a driver status information alarm system using biometric information,

The present invention relates to a driver condition information alarm system using biometric information. More particularly, the present invention relates to a driver condition information alarm system using biometric information, and more particularly, Device and a black box in a vehicle or a display of navigation to thereby enable a passenger to take appropriate measures.

In the case of vehicle operation, the driver is prohibited from operating if the driver's condition is not normal, such as drunk driving because it can cause a fatal situation depending on the driver's condition. However, it is often the case that even if the condition is not clearly identified, such as when you drink alcohol or drugs that prohibit you to drive, you may still be at risk of driving.

For example, if you have chronic illnesses such as hypertension or diabetic patients who require continuous treatment, and you are able to live a normal life because of normal life, if a physical anomaly occurs while you are driving, you may experience fatal accidents . ≪ / RTI >

Even if it is not such a chronic disease, it can be a cause of sudden accidents in the case of a physical abnormality such as drowsiness or fatigue which can not be predicted such as cerebral infarction or heart attack.

In particular, unlike the case of the self-driving, when the vehicle is operated by the business, the vehicle may be operated even if there is a physical discomfort between the vehicles. In such a case, serious injury may occur when a physical abnormality occurs. For example, more precise and systematic safe driving management is needed when the responsibility for the safety of passengers such as buses or taxis, or the damage caused by accidents such as trucks and trailers are large.

However, there is not yet an operational management system that provides integrated safety for the entire operation, so it is necessary to notify the driver of abnormality of the driver's biometric information or to transmit the result to the medical institution And to dispatch an ambulance quickly.

FIG. 1 shows an example of a system for monitoring a driving situation of a driver based on biometric information of a driver.

As shown in the figure, the vehicle 10 is provided in the car 10 to collect the biometric information of the driver through a predetermined sensor, grasp a part of the abnormal situation, deliver it to the remote medical server 30 via the communication network 20, A biometric terminal 11 for delivering the biometric information to the driver and a biometric information provided by the biometric terminal 11 via the communication network 20 and alarm information in accordance with an abnormal situation, And a medical server 30 for providing correspondence information to be transmitted to the driver in accordance with the diagnosis result to the biometric terminal 11 and requesting an external agency to dispatch an ambulance or police.

Through the illustrated configuration, medical information can be provided when the driver's biometric information is abnormal, and basic driver protection can be achieved in which an ambulance or the like is dispatched to a corresponding position when a serious abnormality occurs. Recently, a plurality of sensors are further added to grasp the abnormal situation of the driver, thereby further grasping the abnormal behavior of the driver and the abnormal operation of the steering wheel.

However, the driver's abnormal situation judgment based on the illustrated configuration is merely a judgment of abnormality by summarizing the outputs of various sensors or transmitting the obtained biometric information to the medical institution to judge the abnormality. Therefore, The reliability is low due to the noise of the signal line due to use or the noise due to the driving operation of the driver and the like, so that misjudgment and erroneous dispatch can occur frequently.

On the other hand, if the design change or external control of the vehicle is possible, a technique of automatically parking the vehicle at the shoulder or turning on the emergency light and reducing the speed is introduced. However, It is rather difficult to apply the system because there is a side effect that an accident is caused by such a forced stopping operation because the reliability is low.

Above all, it is difficult to apply for personal use due to such low reliability and loss of dispatch cost due to false alarm. Therefore, when false alarm or malfunction occurs, significant business loss such as operation delay, inconvenience of passenger, It is quite difficult to introduce such an unstable system into a business environment.

However, in situations where accidental accidents are often caused by physical malfunctions of the driver of a business vehicle, in order to secure the safety of the passenger or the adjacent driver, it is necessary to check the stepwise or sudden abnormal situation that may occur to the driver of the business vehicle, It is necessary to introduce an operation management system that can ensure safe operation by preventing unexpected accidents and minimizing operating loss through quick response.

The fixed unit includes a fixed plate fixed to the inner surface of the front window of the vehicle, a fixed plate fixed to the lower surface of the fixed plate and extending a predetermined length downward, Respectively. In the illustrated example, the structure in which the fixed unit is installed in the front window of the vehicle is shown, but the fixed unit is not limited thereto but may be fixed to the ceiling of the vehicle.

The camera body 162 is installed on the front surface of the main body 161 and an installation space for installing the voice input unit 165, the voice recognition unit 166 and the operation unit 180 is provided therein. An auxiliary battery (not shown) is installed in the main body 161 to supply power to the camera 162, the audio input unit 165, the voice recognition unit 166, and the operation unit 180. The battery is connected to a battery of the vehicle so as to be supplied with electricity from the vehicle and charged.

In addition, a display unit for displaying an image photographed through the camera 162 is provided on the rear surface of the main body 161. The display unit may be an LCD panel or an LED panel. An insertion slot (not shown) in which the memory 163 can be inserted is provided on a side surface of the main body 161. Although not shown in the drawing, on the rear surface of the main body 161, It is preferable to provide the above-

The camera 162 is installed on the front surface of the main body 161 and photographs the front of the vehicle through the front window of the vehicle. The camera 162 is connected to the memory 163 and transmits the photographed image to the memory 163.

The memory 163 is inserted into the insertion slot of the main body 161 and stores an image photographed through the camera 162. The memory 163 may be a SD memory 163 card (Secure Digital memory card) having a relatively small size and a relatively large capacity. However, the memory 163 may be a storage device Anything is possible.

The connection unit 164 may be directly connected to the control module through an external connection port (not shown) connected to the control module of the vehicle or may be directly connected to the control module by using a Bluetooth or Zigbee type short- Module and may be connected to an external network and communicate with the control module according to a wireless communication protocol such as Wi-Fi, IEEE, or the like.

Here, the control module of the vehicle integrates an electronic control unit (ECU) of an electric device such as an air conditioner installed in a vehicle, a lamp device including a head lamp, and a window opening / closing device for opening and closing windows, It is preferable that a body control module (BCM: Body Control Module) for integrating and controlling the apparatus is applied.

The voice input unit 165 is installed in the main body 161, and a microphone is applied to collect voice of a passenger boarded in the vehicle. The voice input unit 165 converts an utterance voice of the passenger into an electric voice signal and outputs the voice voice signal to the voice recognition unit 166. On the other hand, the voice input unit 165 may be installed on the dashboard or the steering wheel of the vehicle, in addition to the main body 161, though not shown in the figure.

The speech recognition unit 166 can recognize a user's speech by applying a speech recognition algorithm or a speech recognition engine to the speech signal input from the speech input unit 165. [

At this time, the voice signal can be converted into a more useful form for voice recognition. The voice recognition unit 166 converts the inputted voice signal from an analog signal to a digital signal, detects the start and end points of the voice And detects an actual voice section included in the voice signal. This is called EPD (End Point Detection).

The characteristics such as cepstrum, linear predictive coding (LPC), mel-frequency cepstral coefficient (MFCC), or filter bank energy are detected within the detected interval. A feature vector of the voice data VD can be extracted by applying a vector extraction technique.

The recognition result can be obtained by comparing the extracted feature vector with the trained reference pattern. For this purpose, an acoustic model for modeling and comparing the signal characteristics of speech and a language model for modeling the linguistic order relation of words or syllables corresponding to the recognition vocabulary can be used.

The acoustic model can be divided into a direct comparison method of setting a recognition object as a feature vector model and comparing it with a feature vector of a speech signal, and a statistical method of using a feature vector of a recognition object statistically.

The direct comparison method is a method of setting a unit of a recognition target word, a phoneme, etc. as a feature vector model and comparing how similar the input speech is, and a vector quantization method is typically used. According to the vector quantization method, a feature vector of an input speech signal is mapped to a codebook, which is a reference model, and is encoded into a representative value, thereby comparing the code values with each other.

The statistical model method is a method of constructing a unit of a recognition object as a state sequence and using the relation between the state strings. The state column may consist of a plurality of nodes. The method of using the relation between the state columns is again Dynamic Time Warping (DTW), Hidden Markov Model (HMM), and a method using a neural network.

Dynamic time warping is a method of compensating for differences in the time axis when compared to a reference model, taking into account the dynamic characteristics of the speech, in which the length of the signal varies with time even if the same person pronounces the same. Hidden Markov models, Assuming a Markov process with probabilities and observation probabilities of nodes (output symbols) in each state, we estimate the state transition probability and observation probability of nodes through the learning data, and calculate the probability that the input speech is generated in the estimated model .

On the other hand, the language model modeling the linguistic order relations of words and syllables can reduce the acoustical ambiguity and reduce the errors of recognition by applying the order relation between the units constituting the language to the units obtained by speech recognition. There are statistical language models and Finite State Automata (FSA) based models for language models, and the chained probabilities of words such as Unigram, Bigram, and Trigram are used for statistical language models.

The voice recognition unit 166 is not limited to this, but may be any means for recognizing a voice signal provided through the voice input unit 165.

Although not shown in the drawing, the switch unit 170 is provided in the main body 161 and has a plurality of buttons for the passenger to select either the voice recognition mode or the manual mode. The switch unit 170 transmits a voice recognition mode selection signal to the operation unit 180 when the passenger selects the voice recognition mode and transmits a manual mode selection signal to the operation unit 180 when the passenger selects the passive mode. On the other hand, the switch unit 170 is not shown in the drawings, but may be installed on a dashboard or a steering wheel of the vehicle.

The operation unit 180 generates a control signal corresponding to the voice recognized through the voice recognition unit 166 when receiving the voice recognition mode selection signal from the switch unit 170 and outputs the generated control signal to the connection unit 164 to the control module of the vehicle.

The operating unit 180, which may include a command for controlling the electrical equipment of the vehicle, includes an instruction for indicating the type of the electrical equipment of the vehicle, (Not shown) which stores a plurality of commands and control signals of the electrical equipment corresponding to the respective directives and commands.

The operation unit 180 detects a command word stored in the database among the voice recognized through the voice recognition unit 166 and transmits a control signal corresponding to the detected command to the control module of the vehicle through the connection unit 164 . For example, when the passenger speaks 'turn on the air conditioner' in the vehicle, the voice of the passenger inputted through the voice input unit 165 is recognized by the voice recognition unit 166 and transmitted to the operation unit 180, The control unit 180 detects the directives and commands of 'air conditioner' and 'turn on' from the voice of the passenger, and outputs a control signal for activating the air conditioner corresponding to the directive and the command among the control signals stored in the database, Module.

On the other hand, when receiving the passive mode selection signal from the switch unit 170, the operation unit 180 transmits the control signal to the control module so that the passenger can manually input a control signal for the vehicle electrical device to the control module. send.

The black box 142 according to the present invention configured as described above recognizes the voice of the occupant as well as captures an external image of the vehicle and transmits a control signal to the electronic device of the vehicle, thereby providing a more convenient operating environment to the driver There is an advantage to be able to do.

The controller 130 includes a first wireless communication unit 131 to receive a measurement signal from the bio-signal measurement device 110 wirelessly.

The measurement signal of the bio-signal measurement device 110 transmitted through the first wireless communication unit 131 may be transmitted to the bio-signal analysis unit 134 ).

The bio-signal analyzing unit 134 determines the state of the driver from the measured bio-signals. The bio-signal analyzing unit 134 stores a set value for a bio-signal such as a blood pressure, a pulse, and a blood sugar. When the measured signal is within the set range, it is determined that the apparatus is in a safe state.

If it is determined that the vehicle is in a dangerous state, the control unit 130 displays the dangerous state of the driver to the driver or the passenger through the warning unit 140. [ The control unit 130 controls the voice recognition unit 166 of the black box 142 so that the electrical equipment is activated by the sound of the driver or the passenger through the bio-signal analysis unit 134, And controls the operation part 180 of the black box 142 so that a control signal corresponding to the control signal of the vehicle can be transmitted to the control module of the vehicle.

The warning unit 140 includes a first alarm unit for indicating a dangerous state to the driver and a second alarm unit for indicating a dangerous state to the passenger.

The first alarm unit may be a band-shaped driver's wear device 120 worn on the driver's wrist and may be configured to warn the driver that the measured bio-signal is in a dangerous state such as vibration or lamp blinking.

When the bio-signal measurement device 110 is formed to measure a bio-signal such as a pulse that is worn on the wrist, the bio-signal measurement device 110 may serve as a first alarm unit.

The second alarm unit displays a display of the navigation 141 or the black box 142 to indicate that the occupant traveling in the vehicle recognizes that the driver is in a dangerous state.

The control unit 130 outputs a warning indication through the display of the navigation 141 or the black box 142 and outputs a warning sound so that the passenger can recognize the dangerous state of the driver.

The controller 130 can simultaneously operate the first alarm unit and the second alarm unit, but can operate sequentially.

For example, when the dangerous state of the driver is recognized through the measured bio-signal, the warning signal is first output to the first alarm unit so that the driver is informed of the dangerous state.

The driver responds to the warning signal of the first alarm part to stop the vehicle and to stop the output of the warning signal when the biological signal is returned to the normal state by taking the medicine.

The controller 130 may output a warning signal through the second alarm unit so that the passenger recognizes the dangerous state of the driver when the vehicle continues to run without any improvement for a predetermined period of time after the warning signal is output from the first alarm unit.

Although not shown, the control unit 130 may be provided with passenger monitoring means for detecting whether or not the passenger is present on a seat other than the driver's seat, such as a passenger seat or a rear seat of the vehicle.

The passenger monitoring means may be a weight sensor mounted on a seat other than the driver's seat and sensing the weight of the occupant, or a sensor for determining whether or not the occupant is boarded in the same manner as heat or image shooting. If there is no occupant, May skip the operation of the second alarm unit and proceed to the next step.

The control unit 130 further includes a second wireless communication unit 132 for transmitting status information of the driver to an external main management server 150. [

The second wireless communication unit 132 is a communication unit that can communicate with the Internet communication network. When the biometric signal measured by the driver is out of a predetermined normal range, the second wireless communication unit 132 transmits a driving signal to the driver & A warning signal is output to warn the user of the dangerous state of the battery.

The control unit 130 transmits the information to the main management server 150 through the second wireless communication unit 132 when the driver's biological signal remains in a dangerous state for a predetermined period of time.

In this case, the personal information of the driver, that is, the medical record, medicine information to be taken, and the disease of the driver are stored in the driver database 133 included in the controller 130, And transmits the driver information to the main management server 150 together.

In the main management server 150, the information is transmitted to the medical management server 151 and the operation management server 152 again.

The medical management server 151 transmits the disease information of the driver to the medical institution. The medical management server 151 may transmit the information to the doctor of the driver or the hospital visited by the driver periodically, or may transmit the information to the emergency medical care It may also be possible to send driver information to an institution or a managed hospital to diagnose the driver's current condition.

In addition, the operation management server 152 transmits information such as the elapsed time in the dangerous state including the GPS information of the running vehicle to the vehicle management institution or the rescue organization. This information can be used to speed up follow-up in the event of an accident.

In addition, when the controller 130 transmits personal information of the driver to the main management server 150, the controller 130 encrypts and uploads the corresponding information, and the encrypted personal information can be decrypted and read only at a designated medical institution.

This prevents the driver's personal information from being unnecessarily leaked to the outside.

6 and 7, when the driver first gets on the vehicle, the control unit 130 controls the operation of the driver 130 based on the biometric information according to the present invention, , It is confirmed whether or not the driver is a registered driver through the unique identification code input to the driver wearing device 120 or the living body signal measuring device 110 for measuring the living body signal of the driver.

If the driver is not a registered driver, the driver's personal information can be obtained through a new driver registration process, and customized monitoring can be performed according to the driver's condition.

When the identity of the driver is confirmed, monitoring is started in accordance with the identification information of the driver during driving of the vehicle. A living body signal is acquired through the living body signal measuring device 110 worn by the driver and the driver's state is determined to be in a normal state or a dangerous state through the measured living body signal.

If it is determined that the vehicle is in a dangerous state, the control unit 130 outputs a warning signal to the driver through the first alarm unit.

The driver improves the situation in response to the warning signal. When the bio-signal returns to the normal category, the controller 130 returns to the operating and monitoring state again.

If the situation is not improved even though the warning signal is output to the driver through the first alarm unit, the warning signal indicating the dangerous state of the driver to the passenger is output through the second alarm unit.

The control unit 130 may omit the output of the warning signal through the second alarm unit if the vehicle is not occupied with a sensing means for sensing whether or not the passenger is boarding the vehicle.

If the dangerous state of the driver is not continuously improved, the controller 130 proceeds to the external communication through the second wireless communication unit 132.

Referring to FIG. 7, first, the controller 130 divides the driver's state into the emergency state and the non-emergency state through the biometric signal of the driver. If the driver's state is not an emergency state, And transmits the measured bio-signal information together with the driver's personal information to the primary care physician or the management hospital.

A medical institution or a management hospital receiving medical information can accurately diagnose the driver's condition based on the data and decide the direction of the follow-up action.

If it is determined that the state of the driver determined by the control unit 130 is an emergency, the rescue team can send a rescue signal to the nearby rescue team through the operation management server 152, so that the rescue team can approach the rescue vehicle and receive assistance.

At this time, the control unit 130 transmits the GPS information of the vehicle and the photographed image of the black box 142 together to the operation management server 152, and displays the emergency status of the vehicle through the position and the running state of the vehicle Can easily be judged.

The driver status information alarm system 100 using the biometric information according to the present invention continuously monitors the driver's safety information so that the driver can operate safely based on the biometric information of the driver, , Or the structure of the vehicle is promptly structured in the event of an emergency, so that the life of the driver can be kept more secure.

In addition, since the driver's condition information alarm system 100 utilizing the biometric information according to the present invention recognizes the voice of the driver or the passenger of the vehicle when a dangerous situation occurs, the control signal can be transmitted to the full- The vehicle has a merit that it is possible to operate the electric device of the vehicle.

At this time, the support plate 222 is fixed to the lower end of the elastic members 224 and is elastically supported by the fixing plate 221. Since the support plate 222 is resiliently supported on the fixed plate 221 by the elastic member 224, the support plate 222 and the fixed plate 221 are adjacent to or spaced from each other when vibration is applied from the vehicle 10.

The piezoelectric element 210 is fixed to the stationary plate 221 by a vibration transmitted from the vehicle 10 to generate electricity corresponding to the pressure generated when the stationary plate 221 and the support plate 222 are adjacent to each other. And the support plate 222, as shown in Fig. In the illustrated example, the piezoelectric element 210 is fixed to the fixed plate 221, but the piezoelectric element 210 is not limited thereto and may be fixed to the support plate 222. The piezoelectric element 210 is a conventionally used element that generates electricity by an applied pressure, and a detailed description thereof will be omitted.

Vibration occurs in the vehicle 10 when the vehicle 10 is traveling on a road that is off or not smoothly packed. The vibration causes the stationary plate 221 and the support plate 222 to be adjacent to or spaced from each other. The support plate 222 contacts and presses the piezoelectric element 210 when the fixing plate 221 and the support plate 222 are adjacent to each other and the piezoelectric element 210 generates electricity corresponding to the input pressure, .

The black box 200 configured as described above has an advantage that the amount of electricity supplied from the vehicle 10 can be reduced because the auxiliary battery is charged by generating electricity using the piezoelectric element 210.

9 and 10 show a black box 300 according to another embodiment of the present invention.

The black box 300 includes a sensor 310 connected to the piezoelectric element 210 or the battery to sense an amount of power generated in the piezoelectric element 210, And a determination unit (302) for determining a running road of the vehicle (10) according to the detection information. The sensor unit 310 senses the amount of power generated in the piezoelectric element 210 over time and is a sensing sensor capable of sensing the amount of electric power, which is generally used in the related art, and thus a detailed description thereof will be omitted.

When the amount of power generated in the piezoelectric element 210 is equal to or greater than a preset reference amount for a preset unit time, the determination unit 302 receives the sensing information from the sensor unit 310, As an off-load. At this time, the unit time is preferably 5 minutes to 10 minutes. Vibration of the vehicle 10 is frequently generated when the vehicle 10 travels on an off-road having a relatively large number of concavities and convexities. The amount of power generated from the piezoelectric element 210 by frequent vibration increases, 210 can determine the type of road on which the vehicle 10 travels.

When the amount of power generated in the piezoelectric element 210 during the unit time is less than the reference amount, the determination unit 302 determines the road on which the vehicle 10 travels as a pavement road.

At this time, when the road on which the vehicle 10 travels is discriminated as an off-road through the discrimination unit 302, the operation unit 180 determines whether the passenger mode selection signal is received through the switch unit 170 And transmits the control signal to the control module so as to control the electric device of the vehicle 10 by voice.

As described above, when the driving road of the vehicle 10 is determined as an off road by the discrimination unit 302, the black box 300 operates the operation unit 180 so that the occupant can automatically control the voicing machine by voice Even if the vehicle 10 suddenly enters the off-road, the occupant can use the electric device more conveniently without operating the switch unit 170.
