After notifying the central processing unit of successful EMS data transmission (212), the service center transmission process is terminated (213).

5A to 5E are flowcharts illustrating an interworking method between a wireless communication terminal and a transport device according to the present invention, and FIG. 5A is an overall flowchart of a linkage method between a wireless communication terminal and a transport device, and FIGS. 5B to 5E Detailed process flow chart for each telematics service. Each algorithm is performed by a central processing unit of the cradle device.

First, after attaching the wireless communication terminal to the cradle device and driving the telematics program (300), the central processing unit of the cradle device communicates with the wireless communication terminal to check the communication line (301). As a result of the check, if the communication line does not operate normally, it repeatedly attempts to communicate with the wireless communication terminal, and if the communication line operates normally, the process proceeds to the next step (302).

Subsequently, when an interruption such as an emergency signal, an information signal, a telephone call mode, and a voice guidance occurs, interrupt processing is first performed (303). First, it is determined what interrupt occurred (304, 309, 314, 320).

As a result of the determination, when an emergency signal input comes in (304), the emergency signal input processing process routine proceeds (305). This will be described in detail with reference to FIG. 5B.

As shown in FIG. 5B, the central processing unit notifies the wireless communication terminal that an emergency signal has occurred (306) and waits for an acknowledgment (Ack.) Signal that an emergency signal has been received from the wireless communication terminal (307). If the response signal is not received, the transmission is continuously retransmitted to the wireless communication terminal, and upon receiving the response signal, the emergency signal input processing process is terminated (308).

As a result of the determination, when the information signal input is input (309), the information signal input processing process routine proceeds (310). This will be described in detail with reference to FIG. 5C.

As shown in FIG. 5C, the central processing unit notifies the wireless communication terminal that the information signal has occurred (311) and waits for an acknowledgment (Ack.) Signal that the information signal has been received from the wireless communication terminal (312). If the response signal is not received, the transmission is continuously retransmitted to the wireless communication terminal. If the response signal is received, the information signal input processing process is terminated (313).

As a result of the determination, when the telephone call mode interrupt is generated (314), the telephone call mode process routine proceeds (315). This will be described in detail with reference to FIG. 5D.

As shown in FIG. 5D, the central processing unit mutes the audio output in order not to disturb the voice call when receiving the call mode progress signal from the wireless communication terminal or inputting a speed dial from the user. (316). Then, power is supplied to the audio unit to enable a call (317). When the call mode ends, the phone call mode is terminated after returning the audio output to the state before the call (318).

As a result of the determination, when the voice guidance interrupt is generated (320), the voice guidance process routine proceeds (321). This will be described in detail with reference to FIG. 5E.

As shown in FIG. 5E, the central processing unit mutes the audio output (323) so as not to interfere with the voice announcement broadcast (322) upon receiving the voice guidance output scheduled signal from the wireless communication terminal. Then, power is supplied to the audio unit to enable voice guidance broadcasting (324). Thereafter, upon receiving the voice guidance termination signal from the wireless communication terminal (325), the audio output is returned to its original state (326).

If an interrupt occurs as described above, it moves to the corresponding interrupt and processes the corresponding function, and after processing, it proceeds in the normal flow. That is, the central processing unit receives data from various sensors of the transportation device (327) and transmits the data to the wireless communication terminal (328).

Thereafter, if the power supply is not interrupted, the program continues to run. If the power supply is stopped, the program ends (329).

As described above, in the present invention, by mounting a portable wireless communication terminal (such as a PDA) to a cradle device of a transportation device (such as a vehicle), the wireless communication terminal can communicate with the interface of the transportation device through the cradle device. It will be able to perform key terminal functions for telematics services.

The functions of the wireless communication terminal and the cradle device can be largely defined in four ways. One is to start driving after the user (driver) enters the desired place in the wireless communication terminal, and the device guides the user to the destination by using a GPS, a gyro sensor, an acceleration sensor, etc., with an image (LCD) and a voice (Speaker). The state performs the navigation function. That is, the device searches for the optimal path from the current location to the destination and informs the driver, and the user (driver) can drive to the destination while receiving video and audio guidance from the device. That is, it plays the same role as the function of the car navigation system (CNS).

The other is emergency rescue, one of the Telematics services. This function informs the service center when there is a collision of transportation equipment (vehicle, etc.) or when the user (driver) presses emergency / information / failure. That is, when the collision detection sensor is activated when the vehicle collides, the collision information is informed to the device, the device informs the service center of the information on the collision and the position information of the vehicle through the GPS.

In addition, the device transmits the accident information (collision accident information and location information, etc.) to the service center in a short message and then calls the service center for a voice call with the service center. When the phone is connected, the device is automatically switched to hands-free mode, and an employee of the service center attempts to speak with the occupant to find out the current situation information and reassure the driver that an ambulance or a tow truck will be sent soon if the occupant is informed of the accident. If the passenger is not injured and only the transport equipment is damaged, only the tow truck is sent. The service center will then use the information it receives to inform 119 or 112 of the traffic accident and send an ambulance and a tow truck to the accident site.

Next, it performs hands-free and privacy functions that allow you to make phone calls while driving. When the phone is turned on while driving, it automatically mutes the radio voice so that it does not interfere with the call and automatically returns the radio voice to its original state after the call.

Lastly, the power supply and charging function from the transportation equipment is included so that the wireless communication terminal can be used for a long time. In addition, the detachable function is built-in so that the wireless communication terminal can be used together for the portable and the transportation equipment, so it is mounted on the cradle device for the use of a telematics service system when boarding, and the wireless communication terminal is removed by removing it. Perform a function. Then, when driving at a traffic congestion or accident point, the user (driver) sends traffic congestion area information to the service center by pressing the traffic congestion button, and the service center collects such information from various vehicles and collects the traffic congestion. Determine the area and send traffic information to users. In addition, in order to prevent the traffic congestion information from being transmitted due to user carelessness when removing the wireless communication terminal, the traffic congestion information should not be transmitted during the removal.

On the other hand, in one embodiment of the present invention as described above, but the current location information of the transport device is described by using a GPS method, in case of emergency in the case where the current location of GPS reception is impossible, the wireless communication terminal is wireless It should be equipped with the positioning function using a communication network (CDMA mobile communication network, etc.).

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention provides a low cost telematics service system for navigation and emergency rescue using a portable wireless communication terminal, a cradle device, a collision detection sensor (or an acceleration sensor), a gyro sensor, a vehicle speed sensor, and the like. There is an effect that can be implemented.

In addition, the present invention has the effect of providing a variety of application services that meet the various needs of the user by utilizing a portable wireless communication terminal. That is, the present invention has the effect of providing a high quality telematics service to the user by receiving a road without congestion from the service center in case of emergency, road guidance for rescue roads, and roads with heavy traffic. There is.

In addition, the present invention has the effect of providing a good hands-free function to the user by automatically muting the audio volume when a call is coming or making a call with the audio on while driving.

In addition, according to the present invention, the wireless communication terminal can be used for a long time according to the charging function of the battery of the wireless communication terminal, and the attachment and detachment of the wireless communication terminal can greatly improve the utilization of the wireless communication terminal.

In addition, the present invention can transmit and receive traffic information for a traffic accident area or a congested area, it is possible to travel to the destination by the optimal route in accordance with the guide information from the service center.

In addition, the present invention has a display device that can display the location of the road and the vehicle as a map in the traffic information function as described above, in the case of missing a voice signal can reduce the vehicle speed and check the traffic information through the screen This has the effect of greatly improving the convenience of the driver.

In addition, since the present invention uses a wireless communication terminal such as a personal digital assistant (PDA) to which a display device (LCD) is attached, a wireless module using a code division multiple access (CDMA) method or a GSM method is mounted therein. And with a display device, the Internet is available without a laptop.
