Description

  The present invention relates to an accident situation reporting method using a cellular phone terminal that implements a drive recorder function using the cellular phone terminal, a cellular phone terminal having an accident situation reporting function, and an accident situation reporting program.

  The camera is equipped with a camera that can shoot movies, and when a vehicle accident occurs, the situation for a certain period of time before and after the accident occurs as an image for the purpose of leaving objective evidence for subsequent verification of the cause of the accident. A drive recorder having a function of recording and saving has been proposed.

  However, since the dedicated drive recorder device is expensive, it has not been widely used in general passenger cars. Therefore, a mobile phone terminal with a camera function that has been popular in recent years is fixed to a mobile phone mounting mechanism installed on a dashboard of the vehicle, and a moving image of the front of the vehicle taken by the mobile phone terminal with a camera function while driving the vehicle is captured. Patent Documents 1, 2 and the like describe a technique for providing a function as a drive recorder to a mobile phone terminal with a camera function by recording and saving, and providing a drive recorder system at a low cost.

  For example, a mobile phone terminal having a drive recorder function described in Patent Document 1 includes a camera, a recording memory that records captured image information by the camera, and continuous captured image information by the camera including date and time information and imaging speed information. And a means for storing the data in the recording memory in an auxiliary recording medium when an impact is detected.

  Further, in the mobile phone terminal having the drive recorder function described in Patent Document 1, it is further determined whether there is a possibility of a vehicle fire from the vehicle speed immediately before the collision detection, and the vehicle speed immediately before the collision detection is When the speed is higher than the speed at which a fire may occur, a means for preventing data loss due to a vehicle fire after a collision by sending the contents of the recording memory to a predetermined destination set in advance is provided. Furthermore, after the impact is detected, a safety confirmation request message / announcement is performed to check whether the confirmation key is pressed. If the confirmation key is not pressed for a certain period of time, it is determined that the driver is in an emergency such as injury or fainting. Thus, there is provided means for confirming the safety of the driver by performing data communication with a predetermined security company in cooperation with the data communication function of the mobile phone terminal.

  A mobile phone terminal having a drive recorder function described in Patent Document 2 has a GPS function, and simultaneously receives radio waves from a plurality of GPS satellites to recognize the current position of the vehicle. Thereby, when an accident etc. occur, it becomes possible to specify the occurrence position.

  However, in the technique disclosed in Patent Document 1, in the event of an accident that does not exceed the speed at which a vehicle fire may occur, the moving image data recorded in the memory in the mobile phone terminal is sent to a predetermined destination set in advance. In this case, there is a possibility of falsification of the data which is advantageous to the data submitter.

  Further, in the technique disclosed in Patent Document 1, after the impact is detected, a safety confirmation request message / announcement is performed to check whether the confirmation key is pressed. If the confirmation key is not pressed for a certain time, the driver is injured or fainted. Because the data is communicated to the specified security company in cooperation with the data communication function of the mobile phone terminal, the specified security company is in the emergency situation when the driver does not press the confirmation key. Although it is possible to determine the occurrence and start the rescue operation, there is a problem that when the driver presses the confirmation key, the occurrence of the accident cannot be recognized at that time. Furthermore, since information indicating the location where the accident occurred is not notified when the accident is reported, there is a problem that it is difficult to confirm the location where the accident occurred.

  Although it is conceivable to apply the technology for recognizing the current position of the vehicle shown in Patent Document 1 to Patent Document 1 and notify information indicating the position where the accident occurred, the GPS function is installed in the mobile phone terminal. The mobile phone terminal not equipped with the GPS function cannot be notified of information indicating the position where the accident occurred.

  The present invention has been made in order to solve such problems, and the purpose of the present invention is to carry out an accident processing of an accident situation and an accident occurrence position using a mobile phone terminal not equipped with a GPS function. It is to be able to notify the agency immediately.

Hereinafter, the present invention will be described in detail based on examples.
FIG. 1 is a diagram for explaining a usage pattern of an embodiment of a mobile phone terminal having an accident situation reporting function according to the present invention.

  A mobile phone terminal 12 having an accident situation reporting function according to the present invention is mounted on a dashboard 11 of a vehicle 10, for example. Then, while driving the vehicle 10, a moving image is captured in front of the traveling direction by a camera built in the mobile phone terminal 12. At that time, the mobile phone terminal 12 is set so that the viewing angle of the built-in camera is an optimal viewing angle in which the photographing object 14 such as a traffic light, an intersection, and a pedestrian in front of the vehicle is within the camera viewing field 13. It is installed on the board 11.

  FIG. 2 is a diagram illustrating an example of an attachment structure when the mobile phone terminal 12 illustrated in FIG. 1 is mounted on the dashboard 11 of the vehicle 10.

  An attachment mechanism 24 for fixedly installing the mobile phone terminal 12 on the dashboard 11 of the vehicle is provided. The cellular phone terminal 12 is mounted on the dashboard 11 by the mounting mechanism 24 with the camera lens unit 22 provided in the cellular phone terminal 12 facing the front of the vehicle. The attachment mechanism 24 includes an angle adjustment mechanism 26 and can be adjusted so that the field of view of the camera lens unit 22 is optimized.

  Since the mobile phone terminal 12 always performs operations such as moving image shooting and calculation of the current position (described later) while the vehicle 10 is in operation, it is preferable to employ a method of supplying operating power from an in-vehicle battery. In that case, the electric power received from the cigar plug of the vehicle is converted into electric power that can be used by the mobile phone terminal 12 and used while being connected to the charging terminal of the mobile phone terminal 12 via the battery charging cable 25.

  FIG. 3 is an internal functional block diagram of the mobile phone terminal 12. The cellular phone terminal 12 of this embodiment is photographed by a camera unit 31 having a still image and moving image photographing function, an acceleration sensor unit 32 that determines the occurrence of an accident when acceleration of a predetermined level or more is detected, and the camera unit 31. A memory unit 35 in which the recorded image data and the current position are recorded, a communication unit 34 for transmitting accident information to the accident processing organization via the mobile phone base station, and a control unit 36 for controlling the operation of each of these functional blocks. I have.

  The communication unit 34 is also a configuration for realizing the call function of the mobile phone terminal 12, and further includes a speaker 37, a display unit 38, an operation unit 39, and a microphone 40 as a configuration for realizing the call function. . In addition, a power supply unit 41 including a secondary battery that supplies power for the operation of the mobile phone terminal 12 and a power input terminal 42 for inputting a feeding current from a vehicle-mounted battery or the like via the battery charging cable 25 are provided. I have.

  In the memory unit 35, in addition to the storage unit in which the image data and the current position are recorded, various programs for executing functions provided in the mobile phone terminal 12, a ROM storing data, and a control unit 36 are provided. Various storage units such as a RAM for reading a program stored in the ROM and using it as a work area when executing various functions according to the program are included. The control unit 36 and the memory unit 35 have a function as a computer for executing an operation program provided in the mobile phone terminal 12.

  FIG. 4 is a flowchart showing a specific processing operation executed by the control unit 36. The processing operation of the control unit 36 according to this flowchart will be described below.

  The mobile phone terminal 12 is attached to an attachment mechanism 24 provided on the dashboard 11 of the vehicle 10 to be driven, and adjusted by the angle adjustment mechanism 26 so that the camera lens unit 22 faces forward. The liquid crystal display unit 21 confirms that the situation is displayed. Next, by performing an operation for starting the drive recorder mode from the operation unit 39, the cellular phone terminal 12 starts the drive recorder operation from step S1.

  Steps S2 and S5 represent the start and end of the loop process, and until there is an interrupt process (drive recorder mode stop input from the operation unit 39 or impact detection by the acceleration sensor unit 32), which is an end condition. This loop processing is executed.

  In step S3, the current position of the terminal, that is, the current position of the vehicle 10 is calculated (calculation of position information). Although the calculation of this position information will be described later, the current position of the terminal is calculated from the position of the base station and the distance between the base station and the mobile phone terminal 12 transmitted from a plurality of base stations. The calculated position information is stored in the memory unit 35. Since the memory unit 35 is finite, when data accumulates for a certain period of time, the oldest data is overwritten in order.

  In step S <b> 4, the moving image data ahead of the vehicle photographed by the camera unit 31 is compressed by the control unit 36, and the compressed moving image data is stored in the memory unit 35. Since the memory unit 35 is finite, when data accumulates for a certain period of time, the oldest data is overwritten in order. Steps S3 and S4 are processed in parallel.

  When the acceleration sensor unit 32 detects an impact equal to or higher than the set level, or when there is a drive recorder mode stop input from the operation unit 39, an interrupt process is performed, and the loop process end condition is satisfied. The loop process of S5 ends.

  In step S6, a file name is assigned to the position information stored in the memory unit 35 when the loop process is completed, and the position information is stored in the memory unit 35. In step S7, the moving image data stored in the memory unit 35 at the time when the loop processing is completed is given a file name and stored in the memory unit 35. Steps S6 and S7 are processed in parallel.

  In step S8, the interrupt type is confirmed. If the interrupt process is due to impact detection, the process proceeds to step S9. In step S9, the position information data and the moving image data stored in steps S6 and S7 are transmitted to an accident handling organization that is set in advance using the mobile phone function.

  In step S10, the drive recorder mode is stopped. In step S8, the interrupt type is confirmed. If the operation recorder 39 is used to stop the drive recorder mode, the process immediately proceeds to step S10 to stop the drive recorder mode.

  5 and 6 are conceptual diagrams for calculating position information in step S3. FIG. 5 shows a procedure for transmitting a DPCCH / DPDCH frame between the mobile phone terminal 12 and the base station 100, and FIG. 6 shows the position of the base station 100 and between the mobile phone terminal 12 and the base station 100. This shows how the position coordinates (current position) of the mobile phone terminal 12 can be calculated from the distance r.

  In FIG. 5, TA indicates “the time from when the base station transmits a downlink DPCCH / DPDCH frame to when the mobile phone terminal receives it”, and TB indicates “the uplink DPCCH after the mobile phone terminal detects the downlink DPCCH / DPDCH frame” TC indicates “time from transmission of uplink DPCCH / DPDCH frame by mobile phone terminal to reception by base station”, TX indicates “time from base station to downlink DPCCH The time from when the / DPDCH frame is transmitted to when the upstream DPCCH / DPDCH frame is received is shown.

  According to “3GPP TS25.211, 7.6.3 Uplink / downlink timing at UE”, the mobile phone terminal 12 (UE) transmits the uplink DPCCH / DPDCH frame to the base station 100 in accordance with the corresponding downlink DPCCH / This is performed 1024 chips (266.6 usec) after the first detection of the DPDCH frame. That is, in FIG. 5, TB becomes TB = 266.6 usec. Therefore, the base station 100 can calculate the distance r to the mobile phone terminal 12 from the delay time TX from the transmission of the downlink DPCCH / DPDCH frame to the reception of the uplink DPCCH / DPDCH frame.

  Also, as shown in FIG. 6, if the distance r1 between the base station 100A and the mobile phone terminal 12 is known, the mobile phone terminal 12 is located somewhere on a circle with a radius r1 centered on the position of the base station 100A. It can be seen that is located. If the distance r1 between the mobile phone terminal 12 and the base station 100A and the distance r2 between the mobile phone terminal 12 and the base station 100B are known, a circle with a radius r1 centered on the position of the base station 100A and the base station 100B It can be seen that the mobile phone terminal 12 is located at one of the two points where the circle with the radius r2 centering on the position of. If the distance r1 between the mobile phone terminal 12 and the base station 100A, the distance r2 between the mobile phone terminal 12 and the base station 100B, and the distance r3 between the mobile phone terminal 12 and the base station 100C are known, the base station The mobile phone terminal 12 is at one point where a circle with a radius r1 centered on the position of 100A, a circle with a radius r2 centered on the position of the base station 100B, and a circle with a radius r3 centered on the position of the base station 100C intersect. You can see that it is located.

  Therefore, in this embodiment, each base station 100 calculates the distance r to the mobile phone terminal 12 from the delay time from transmission of the downlink DPCCH / DPDCH frame to reception of the uplink DPCCH / DPDCH frame. The calculated distance r is sent to the mobile phone terminal 12 together with its own position (base station position). In this case, the mobile phone terminal 12 calculates the current position of the mobile terminal from the position of the base station 100 sent from at least three base stations 100 and the distance r between the base station 100 and the mobile terminal, The calculated current position of the terminal is stored in the memory unit 35 as the current position of the vehicle 10.

  As can be seen from the above description, according to the present embodiment, the mobile phone terminal 12 having a video shooting function by a camera is provided with a video storage function (drive recorder function) when an accident occurs, so that the vehicle 10 at the time of the accident occurs. Since the video data (image data) ahead of the vehicle's running direction and the current location of the terminal (the current location of the vehicle 10) at the time of the accident are automatically transmitted to the predetermined accident processing organization, the accident location and accident situation are handled as an accident It is possible to contact the executing agency accurately and quickly, and prompt relief activities are possible. In addition, there is no possibility of data falsification by the data submitter during the post-processing of the accident, and it becomes possible to provide reliable evidence.

  In addition, since the current position of the own terminal (current position of the vehicle 10) is calculated from the position of the base station 100 sent from a plurality of base stations 100 and the distance between the base station 100 and the own terminal, It is not necessary to use a high-performance mobile phone terminal 12 having a GPS function, and instead of an expensive dedicated drive recorder, a mobile phone terminal owned by anyone can be used as a drive recorder. The cost can be further reduced, and further contribution can be made to promote the popularization of drive recorders.

  FIG. 7 is a flowchart illustrating another example of the processing operation executed by the control unit 36. In this example, the video data at the time of the accident and the location of the accident are automatically transmitted to the designated accident handling organization, and then the voice line connection is automatically executed with the accident handling organization to enable voice communication. A means to make it.

  In FIG. 7, the operations in steps S1 to S10 are the same as those in the flowchart shown in FIG. 4, so the operations in steps S11 to S14 added mainly in this example will be described below.

  In this example, when an interruption due to impact detection occurs, the control unit 36, in step S9, sets the location information and moving image data stored in steps S6 and S7 in advance using the mobile phone function. After transmitting to the executing agency, the process proceeds to step S11 to connect a voice line with the accident handling agency.

  When the off-hook operation is performed on the accident handling engine side, the call state is set (step S12), and the driver or the passenger gives the accident handling engine side a detailed situation such as the situation of the accident and the state of the injury by voice call. It becomes possible to report. In step S13, an end call request (input from the terminal operation unit 39 or a disconnection request from the network side) is detected, and if there is no end call request, the process returns to step S12 to continue the call state.

  If there is a call termination request, the process proceeds to step S14 to disconnect the voice line, and after disconnection of the voice line is completed, the process proceeds to step S10 to end the drive recorder mode.

  According to this example, the acceleration sensor unit 32 automatically transmits the moving image data and the location where the accident occurred when the acceleration sensor 32 detects an impact of a set level or more and determines that an accident has occurred, to the predetermined accident processing execution engine, Since the voice line is automatically connected between the two, the situation at that time can be directly heard from the driver or passenger. In addition, when there is no response from the driver, it can be predicted that the driver is in an unresponsive state, and prompt and appropriate rescue activities are possible.

  Although the acceleration sensor unit 32 detected an impact exceeding the set level and the moving image data and the location of the accident at that time were automatically transmitted to a predetermined accident processing execution engine, the accident did not actually occur. In such a case, the situation at that time can be confirmed directly from the driver through the voice line, so that there is an effect that it is not necessary to perform useless rescue activities or post-processing.

  At this time, the driver is notified that the drive recorder mode is temporarily terminated after disconnection of the voice line in step S14 because the driving operation is performed such that the acceleration sensor unit 32 detects an impact of the set level or more. In addition, it is possible to instruct the driver to start the drive recorder mode in step S1 in order to resume the drive recorder mode, and to alert the driver to prevent accidents.

  An accident situation reporting method using a cellular phone terminal according to the present invention, a cellular phone terminal having an accident situation reporting function, and an accident situation reporting program are various vehicles as a drive recorder using a cellular phone terminal not equipped with a GPS function. It is possible to use it.
