Figure 1 is a block diagram of an accident notification system according to an embodiment of the present invention, Figure 2 is a block diagram of an electronic compass according to another embodiment of the present invention, Figures 3a to 3f is a preferred embodiment of the present invention FIG. 1 is a diagram illustrating a change in acceleration data measured by a portable terminal having an electronic compass according to an embodiment.

Referring to FIG. 1, in the accident detection system according to the present invention, the portable terminal 100 and the accident occurrence information receiving server 190 are connected through a communication network.

Here, the communication network may include a mobile communication network including a base transceiver station (BTS), a base station controller (BSC), and a packet data serving node (PDSN) and a wired / wireless internet network.

 As shown in FIG. 1, the portable terminal 100 according to the present invention includes an electronic compass 110, a signal processor 115, an accident determiner 120, a transceiver 125, a storage 130, An input unit 135, a display unit 140, a sound output unit 145, a location information generator 150, and a controller 155 are included.

As shown in FIG. 2, the electronic compass unit 110 may include a sensor unit 210 and an A / D converter 215. The electronic compass unit 110 may calculate acceleration data through the corresponding sensor unit 210 to calculate a signal processor. Forward to 115. Here, the sensor unit 210 is provided with a three-axis acceleration sensor to measure the acceleration of the movement to each axis to convert the digital acceleration data through the A / D conversion unit 220 to transmit to the signal processing unit 115 Can be.

The acceleration sensor is a sensor for measuring the earth's gravity, and each acceleration sensor (ie, X-axis acceleration sensor, Y-axis acceleration sensor) in three mutually orthogonal directions (for example, in the X, Y, and Z directions). , Z-axis acceleration sensor), and analog acceleration data may be generated and transmitted to the A / D converter 220 using the voltage value measured by the acceleration sensor of each axis.

For example, the AC component of the voltage value measured by the acceleration sensor is an acceleration component for movement, and the DC component may be an angle formed between the direction of the earth's gravity (ie, the earth's center) and the axis of the sensor. In addition, scalar data of gravity may be calculated using acceleration sensors (eg, X-axis acceleration sensor, Y-axis acceleration sensor, and Z-axis acceleration sensor) of each axis disposed perpendicular to each other on each axis. have.

For example, the acceleration sensors arranged in the direction of each axis may generate and output the acceleration data only in the acceleration sensor arranged in the axial direction in which the movement occurs in any axis. That is, if the acceleration sensors are arranged orthogonally to each other in the 3 axis direction and are moving in the X axis direction, the acceleration data is output only from the acceleration sensor arranged on the X axis, and the acceleration data is output from the Y axis acceleration sensor and the Z axis acceleration sensor. It may not be.

Although not described herein, each sensor may include an amplifier (not shown) capable of amplifying the measured signal into a signal of a predetermined level or more, and amplifying and outputting the measured signal to a predetermined signal size or more. have.

In addition, the sensor unit 210 may further include a magnetic sensor, an angular velocity sensor, an inertial sensor, a gyroscope, a gyro sensor, and the like, which measure the earth magnetic field in addition to the three-axis acceleration sensor.

The magnetic sensor measures the earth's magnetic field at the observation point and, for example, is arranged so that the three magnetic sensors are orthogonal to each other to measure the direction and intensity of the three-axis magnetic field, thereby converting the three-dimensional magnetic vector data into the A / D converter 215. Can be delivered to. In addition, the magnetic sensor may be implemented as, for example, a three-axis flux gate or two-axis flux gate magnetic sensor according to an implementation method, and may include, for example, an inclination sensor and a magnetic detection element. . In addition, it is apparent that the magnetic sensor may have various configurations, such as a 3-axis Hall sensor, a 3-axis MR (Magento Resistive) sensor, and a 3-axis Magneto Impedance (MI) sensor. Here, the flux gate magnetic sensor magnetically uses a high permeability material such as permalloy to exert an excitation magnetic field by a coil and uses the magnetic saturation and nonlinear magnetic characteristics of the magnetic core to be proportional to the external magnetic field. A device that measures the magnitude and direction of the earth's magnetic field by measuring the second harmonic component.

Here, the inclination sensor (not shown) is supported by the piezoelectric element, which is an example of the piezoelectric element, the pivot body can be measured by the piezoelectric element detects the displacement of the pivotal body. In addition, the magnetism detecting element (not shown) performs a function of detecting and outputting a magnetic component in the vertical direction, for example, a magnetoresistive element such as a Hall element (not shown) or a magnetoresistive element such as an MR element. Can be.

The A / D converter 215 converts the analog signal measured by the sensor unit 210 into a digital signal. Thus, the analog signal measured by the sensor unit 210 may be converted into a digital signal and transferred to the signal processor 115.

The signal processor 115 converts the acceleration data input from the electronic compass unit 110 according to a predetermined algorithm (hereinafter referred to as "converted acceleration data") and transmits it to the controller 155. In addition, according to the implementation method, the signal processor 115 may include a low pass filter to filter the acceleration data input from the electronic compass unit 110. Since the low pass filter is obvious to those skilled in the art, a detailed description thereof will be omitted.

For example, the signal processor 115 may convert the acceleration data input from the electronic compass unit 110 into positive acceleration data by using Equation 1 below and transmit the converted acceleration data to the controller 155.

Here, x, y, z are AC components of the voltage value measured by the acceleration sensor of each axis, the acceleration data is a real value. Also, as shown in Equation 1, K is a value obtained by taking the square root after summing and summing the acceleration data measured and output from the acceleration sensor of each axis, which may be a positive real value.

In addition, according to an implementation method, the signal processor 115 may integrate the converted acceleration data to calculate predetermined speed data per unit time (for example, second) and transmit the predetermined velocity data to the accident determination unit 120. In this case, the accident determination unit 120 may determine whether an accident occurs by analyzing a change pattern of speed data for a predetermined time.

The accident determiner 120 receives the acceleration data converted from the signal processor 115 under the control of the controller 155, generates an acceleration change pattern, and compares it with a predetermined pattern to determine whether an accident occurs. If it is determined that an accident has occurred, the accident determination unit 120 generates accident detection information and transmits it to the control unit 155.

First, for convenience of understanding and explanation, the patterns of acceleration data and transformed acceleration data according to movements will be described with reference to FIGS. 3A to 3D.

3A to 3C are graphs showing acceleration data output from an acceleration sensor of each axis according to a change in time, and FIG. 3D is a data calculated by taking a square root after summing and summing acceleration data of each axis (ie, converted acceleration) Data) is a graph showing the change in time. As shown in FIG. 3D, when the change in the momentum changes rapidly, it can be seen that the change in the converted acceleration data according to the change in time is large.

During the normal operation of the vehicle equipped with the mobile terminal 100, the acceleration data converted for a certain time gradually increases and then the acceleration data converted for a certain time is gradually changed even when there is no change and the vehicle decelerates and stops. You will see a decreasing pattern of change. However, when an accident occurs in the vehicle, as shown in FIG. 3E, the acceleration data converted for a predetermined time is drastically reduced. If the graph of FIG. 3E is approximated, it can be seen that the pattern shown in FIG. 3F is shown. It may be determined whether an accident occurs using the change pattern as shown in FIG. 3E, but may be determined using the approximated change pattern as shown in FIG. 3F. In the present specification, as illustrated in FIG. 3F, an approximated change pattern is stored in the storage unit 130 to determine whether an accident occurs.

Accordingly, the accident determination unit 120 may determine whether an accident has occurred by determining whether the converted acceleration data input from the signal processor 115 is rapidly changed for a predetermined time.

The transceiver 125 performs a function of data transmission and reception with the accident occurrence information receiving server 190 through a communication network under the control of the controller 155. For example, the transceiver 125 may receive accident occurrence information from the controller 155 and transmit the incident occurrence information to the accident occurrence information receiving server 190 through a communication network.

The storage unit 130 inputs the converted acceleration data calculated from the signal processor 115 under the control of the controller 155, the acceleration data of each axis generated from the electronic compass unit 110, and the position information generator 150. Location information, an operation program of the portable terminal 100, a predetermined signal processing algorithm, and the like are stored. In addition, the storage unit 130 stores a voice message (hereinafter, referred to as a transmission cancellation voice message) set in advance in response to the command of canceling the occurrence of the accident information.

In the present specification, the "incident occurrence information transmission cancel command" refers to a command transmitted by the input unit 135 to the control unit 155 when a preset function button is pressed in response to canceling the accident occurrence information transmission from the user through the input unit 135. It is defined as.

The input unit 135 is a means for receiving a control command for controlling the operation of the portable terminal, a function selection command (for example, an accident occurrence information transmission cancel command), and the like from the user. For example, the input unit 135 may include a plurality of key buttons (for example, numeric / character keys, a symbol key of * or #, one or more function keys (for example, a menu key, a call key, a confirmation key, and a wireless Internet). Key for connection)) or a touch screen or the like.

The display unit 140 performs a function of displaying image data, image data, text data, numeric data, and the like under the control of the controller 155. For example, the display unit 140 may be a liquid crystal display (LCD).

The sound output unit 145 may include a sound source chip (for example, Yamaha) as a means for outputting sound. The sound output unit 145 may be, for example, a speaker. For example, if a user inputs an accident occurrence information transmission cancel command through the input unit 135 by the user, the controller 155 reads a transmission cancel voice message stored in the storage unit 130 to the sound output unit 145. Can be delivered to the outside.

The location information generator 150 receives a signal from a GPS (Global Positioning System) satellite (for example, 27 satellites including 3 supplementary satellites) including a GPS receiver (not shown) to locate the portable terminal 100. The information is generated and transferred to the controller 155. For example, the location information generator 150 may use differential GPS (DGPS) to reduce the error range to within 5 m. In addition, the location information generating unit 150 uses a signal received from the GPS satellite every unit time (for example, 1 second) per unit time and uses the time information until the signal is received from the GPS satellite in the GPS satellite. By compensating for the received signal, location information of the portable terminal may be generated and transmitted to the controller 155.

The controller 155 may include internal components of the portable terminal 100 according to the present invention (for example, the electronic compass unit 110, the signal processor 115, the accident determination unit 120, the transceiver unit 125, The storage unit 130, the input unit 135, the display unit 140, the sound output unit 145, the location information generator 150, and the like.

In addition, the controller 155 receives the accident detection information from the accident determination unit 120 and generates an accident if a user does not input the accident occurrence information transmission cancellation command from the input unit 135 within a predetermined time (for example, 10 seconds). The information may be generated and transmitted to the accident occurrence information receiving server 190 through the transceiver 125. Here, the accident occurrence information may be information including location information, user identification information (for example, a portable terminal identification number) received by the controller 155 from the location information generation unit 150, and the like.

In addition, the controller 155 may determine that an accident does not occur or is a minor accident when an instruction for canceling transmission of accident occurrence information is input from the input unit 135 so as not to transmit the accident occurrence information to the accident occurrence information receiving server 190. have. In addition, the controller 155 may read out the transmission cancel voice message stored in the storage 130 and output the same through the sound output unit 145 according to the accident occurrence information transmission cancel command. For this reason, the controller 155 may recognize that the corresponding accident occurrence information is not transmitted to the accident occurrence information receiving server 190.

In addition, the controller 155 may determine whether the vehicle is driven by using the converted acceleration data input from the signal processor 115. If it is determined that the vehicle is in operation, the controller 155 may set the mode set to be updated according to whether the vehicle is running or the driving mode. Therefore, the controller 155 determines that an accident has occurred when the accident detection information is input from the accident determination unit 120 while the driving mode is set to the driving mode, and includes the location information input from the location information generation unit 150. Accident occurrence information may be generated and transmitted to the incident occurrence information receiving server 190.

The accident occurrence information receiving server 190 receives the accident occurrence information from the portable terminal 100 through a communication network and performs a function of reading and contacting contact information registered in advance by a user from a user information database (not shown). In addition, the accident occurrence information receiving server 190 extracts accident location information and user identification information from the accident occurrence information. In addition, the accident occurrence information receiving server 190 may read the identification information of the user from the user information database by using the user identification information and transmit the identification information along with the accident location information to the police station and the server (not shown) of 119. In addition, according to the implementation method, the accident occurrence information receiving server 190 may convert the accident location information and the read identity information into a voice signal according to a predetermined algorithm and transmit the corresponding information through the telephone connection of the police station and 119.

In addition, the accident occurrence information receiving server 190 generates an accident occurrence notification text message using the accident occurrence information input from the portable terminal 100 to the contact information previously registered in the user information database by the police station, 119, and the user. You can also send it to a registered location (eg insurance company, family, etc.).

Here, the user information database maps the user's identification information to the user's identity information (for example, the user's name, user's social security number, etc.), contact information (for example, phone numbers of family members and friends to contact, insurance companies to contact Phone number, etc.). Of course, it may also store more information than is necessary (e.g., necessary for handling incidents).

4 is a flowchart illustrating a method of detecting whether an accident occurs by using a portable terminal having an electronic compass according to an exemplary embodiment of the present invention. According to the present invention, when an accident occurs while a vehicle equipped with the portable terminal 100 is in operation, accident detection information (for example, accident location information, user identification information, etc.) is automatically detected by the accident occurrence information receiving server 190. Information), the incident occurrence information receiving server 190 may receive the information, extract the user identification information, and read and contact the identity information and the contact information mapped accordingly. That is, when it is determined that the vehicle equipped with the portable terminal 100 is in operation, the electronic compass unit 100 provided in the portable terminal 100 may perform the function of the vehicle accident detector.

In operation 410, the controller 155 determines whether the vehicle is in operation.

The location information generating unit 150 uses a signal received from the GPS satellites at a predetermined time (for example, 1 second, 3 seconds, etc.) to reach the corresponding signal from the GPS satellites to the portable terminal 100. The location information of the portable terminal 100 may be generated and transmitted to the controller 155 using the information. In addition, the controller 155 receiving the location information may store the corresponding location information in the storage 130. For this reason, the controller 155 may know the position information according to the movement of the vehicle equipped with the portable terminal 100. As described above, the controller 155 receives the location information from the location information generation unit 150 at a predetermined time to know the location information according to the change of the movement caused by the vehicle. Here, the controller 155 may receive the location information from the location information generation unit 150 every predetermined time (for example, 1 second, 3 seconds, etc.) and store the location information in the storage unit 130. Therefore, the controller 155 calculates the distance information moved during t-1 and t time by using the t-1 time information stored in the storage 130 and the t time location information input from the location information generator 150. can do. That is, the controller 155 may determine whether the vehicle is running by calculating distance information of the vehicle moving for a predetermined time (for example, 1 second and 3 seconds).

Here, of course, according to the implementation method, the controller 155 may calculate the speed information by differentiating the calculated distance information to determine whether the vehicle is running based on this.

As described above, the controller 155 compares the distance information or the speed information moved for a certain time with preset reference information (for example, the movable reference distance information, the reference speed information, etc., for a predetermined time). It may be determined whether the vehicle is running.

If it is determined that the vehicle is not running, the flow proceeds to step 410.

However, if it is determined that the vehicle is in operation, the electronic compass unit 110 generates acceleration data at a predetermined time interval (for example, 1 second) through the sensor unit 210 provided in step 415 to process the signal 115. To pass).

For example, since the AC component of the voltage value measured from the 3-axis acceleration sensor is acceleration data about movement, the electronic compass unit 110 may generate only the corresponding acceleration data and transmit it to the signal processor 115. That is, the electronic compass unit 110 may convert analog acceleration data of each axis input from the sensor unit 210 into digital acceleration data through the A / D converter 220 and transmit the digital acceleration data to the signal processor 115.

In operation 420, the signal processor 115 converts the input acceleration data using a predetermined algorithm and transmits the acceleration data to the accident determination unit 120 under the control of the controller 155. Here, the controller 155 may map the converted acceleration data input from the signal processor 115 to time information and store the mapped acceleration data in the storage 130.

For example, the signal processing unit 115 may filter the acceleration data input from the electronic compass unit 110 using a low pass filter. The signal processing unit 115 converts the acceleration data into the control unit 155 by using Equation 1 as described above. I can deliver it. For example, the signal processor 115 may convert the acceleration data input from the electronic compass unit 110 into a positive real value (converted acceleration data) and transmit the converted acceleration data to the controller 155. In addition, according to the implementation method, the signal processor 115 may calculate the velocity data by integrating the acceleration data input from the electronic compass unit 110 and transmit the velocity data to the controller 155.

In operation 425, the accident determination unit 120 generates a change pattern for a predetermined time (for example, 3 seconds) using the converted acceleration data input from the signal processing unit 115 under the control of the control unit 155. It determines whether an accident occurs by comparing with a predetermined change pattern.

If it is determined that no accident has occurred, the process proceeds to step 410.

However, if it is determined that an accident has occurred, the accident determination unit 120 generates accident detection information and transmits it to the control unit 155 in step 430.

In step 435, when the accident detection information is input, the controller 155 receives the location information input from the location information generation unit 150 and the user identification information read from the storage unit 130 (for example, the portable terminal 100). By using the telephone number) to generate the accident occurrence information and transmits to the transceiver 125.

Here, the controller 155 does not transmit the accident occurrence information to the transmitter / receiver 125 when a command for canceling accident occurrence information is input from the user through the input unit 135 within a predetermined time (for example, 10 seconds). For this reason, it may be possible to cancel the transmission of accident occurrence information in case of no accident or very minor accident.

For example, the controller 155 may notify the user through the sound output unit 145 of a voice message (preset) indicating that the accident occurrence information will be transmitted to the accident occurrence information receiving server 190. In this case, if a command for canceling transmission of accident occurrence information is input by the user within a predetermined time (for example, 10 seconds) through the input unit 135, the controller 155 does not transmit the accident occurrence information to the transceiver 125. You may not.

In operation 440, when the accident occurrence information is input from the controller 155, the transceiver 125 transmits the incident occurrence information receiving server 190 through the communication network.

Here, the accident occurrence information receiving server 190 which receives the accident occurrence information through the communication network identifies the user by extracting an identification number from the received accident occurrence information. Then, the insurance company and family (or acquaintances) registered in the accident occurrence information receiving server 190 to notify the user that the accident occurred while driving the vehicle. In addition, the accident occurrence information receiving server 190 uses the accident occurrence information from the user information database (not shown) accident location information, accident occurrence time information, user identification information (for example, user name, age, gender, Identification information such as a resident registration number) may be read to generate accident information and transmitted to a police station and a server of 119 (not shown). For this reason, when an accident occurs while the user is driving the vehicle, an insurance company, a family member, a police station, 119, or the like may be automatically notified of the accident without a separate process for notifying the occurrence of the accident. If a user cannot be notified of the accident directly due to serious injury, the accident can be notified automatically.

 In FIG. 4, when the portable terminal 100 is installed in a vehicle, the portable terminal 100 operates as a vehicle accident detector to automatically transmit accident occurrence information to the accident occurrence information receiving server 190 when an accident occurs in the vehicle, and the accident occurrence information receiving server 190. Has been described with a focus on a method of notifying an accident occurrence to each insurance company, family, police station, 119, etc., but may be equally applicable even when an accident occurs while the user is carrying the portable terminal 100.

In another embodiment, when the accident occurrence information receiving server 190 is not a user registered in the user information database (not shown) included in the user identification information included in the accident occurrence information received from the portable terminal 100, an accident occurs. The information receiving server may extract the location information included in the accident occurrence information. Using this, the accident occurrence information receiving server 190 may generate accurate accident location information using pre-stored map (map) data and transmit the corresponding accident location information to the police station (ie, 112) and 119.

In addition, the accident occurrence information receiving server 190 transmits the user identification information (for example, the phone number of the mobile terminal 100) and a message informing the occurrence of the accident to the mobile carrier connected through the communication network to identify the user information When requesting the identification information is received from the mobile carrier may transmit it to the police station (ie, 112) and 119.
