The cradle GPS module 230 receives GPS data from at least three or more GPS satellites and calculates GPS location information using the GPS data. Hereinafter, GPS location information calculated by the cradle GPS module 230 provided in the terminal cradle 200 will be referred to as cradle calculated GPS location information.

The cradle control unit 270 transmits the guide mode to the detachable watch module 300 as one of a terminal interlocking mode and a terminal non-interlocking mode. That is, depending on whether the mobile communication terminal 100 and the terminal cradle 200 are interlocked with a short-range wireless connection, an information output type output from the separate watch module 300 may be determined as a terminal interlocking mode or a terminal non-interlocking mode. In more detail, the cradle control unit 270, when wirelessly interlocked with the mobile communication terminal, collects route guidance information received from the mobile communication terminal 100 or the GPS guide information calculated by the cradle GPS module 230 as a separate watch module 300. ) In a short-range wireless transmission mode, in case the mobile communication terminal 100 is not wirelessly linked, a terminal non-interlocking mode that wirelessly transmits the GPS guide information calculated by the cradle GPS module 230 to the separate watch module 300 It can operate in any one of the modes.

The terminal interlocking mode refers to a state in which the short-range wireless link connected data can be transmitted and received between the terminal short-range wireless communication unit 160 of the mobile communication terminal 100 and the cradle short-range wireless communication unit 220 of the terminal cradle 200. Therefore, in the terminal interlocking mode, the navigation application 180 of the mobile communication terminal 100 transmits route guidance information through the cradle short-range wireless communication unit 220 linked to the terminal short-range wireless communication unit 160, and the terminal cradle 200 The cradle control unit 270 transmits the route guidance information received from the mobile communication terminal 100 or the GPS guide information calculated by the cradle GPS module 230 to the detachable watch module 300 in a short range. The detachable watch module 300 outputs the received route guidance information or GPS guidance information.

Here, the route guidance information is information generated and received by the navigation application 180 of the mobile communication terminal 100, and may correspond to route guidance information to a destination, rest area guidance information, and the like. For reference, FIG. 7 is a diagram illustrating a state in which road guidance information is displayed on the detachable watch module 300 as a terminal interlocking mode. When operating in the terminal-linked mode, the detachable watch module 300 can briefly display the driving route direction to the destination as route guidance information, so that the driver can intuitively know the driving route. In addition, the road guidance information may correspond to lane guidance information when lane guidance is required. For example, when a right or left turn is required in front of 100m in front, a lane information guide to use the first and second lanes may be displayed through the watch module 300. In addition, the GPS guide information may include at least one or more of a current speed, a current time, a current location, and a crackdown camera location.

Therefore, when the mobile communication terminal 100 and the short-range wireless communication are connected to receive the road guide information and operate in the terminal interlocking mode, the cradle control unit 270 stores the received road guide information or the self-generated GPS guide information as a separate watch. It can be output through the module 300. For example, in the case of driving on the road, if there is a destination setting, a driving route may be guided, a rest area may be guided, or road guidance information such as lane information may be output. In addition, it is possible to output GPS guide information that displays a current speed, a current position, a current time, or the like, or displays a warning of the enforcement camera when the enforcement camera approaches.

For reference, FIG. 9 shows a navigation guide map through the display window of the mobile communication terminal 100 when the mobile communication terminal 100 is mounted on the terminal holder while the mobile communication terminal 100 is interlocked with the terminal holder for short-range wireless communication. It is displayed and is a picture showing a state in which road guide information or GPS guide information is displayed through the detachable watch module 300. FIG. 9(a) is a diagram showing the way guidance information received through short-range wireless communication from the mobile communication terminal 100 in a state in which the mobile communication terminal 100 is mounted is displayed on the detachable watch module 300, 9(b) is a diagram showing a state in which GPS guide information indicating a rest area distance is displayed on the detachable watch module 300 while the mobile communication terminal 100 is mounted, and FIG. 9(c) is a mobile communication terminal ( 100) is a picture showing a state in which GPS guide information indicating the camera distance and speed limit is displayed on the detachable watch module 300.

In addition, FIG. 10 is a diagram illustrating a case in which the mobile communication terminal 100 is interlocked with the terminal holder 200 for short-range wireless communication, but the mobile communication terminal 100 is not mounted on the terminal holder 200. 10(a) shows that route guidance information received from the mobile communication terminal 100 through short-range wireless communication in a state in which the mobile communication terminal 100 is not mounted is displayed on the detachable watch module 300. . Fig. 10(b) is a picture showing a state in which GPS guide information indicating a rest area distance is displayed on the detachable watch module 300 without the mobile communication terminal 100 mounted thereon, and Fig. 10 (c) is a diagram showing a state in which GPS guide information indicating the intermittent camera distance is displayed on the detachable watch module 300 in a state in which the mobile communication terminal 100 is not mounted.

Eventually, when operating in the terminal interlocking mode, route guidance information displayed on the mobile communication terminal 100 can be distributed and output through the detachable watch module 300 mounted on the terminal cradle 200. Optimization and visibility can be improved. For example, important road guidance information (direction, distance, etc.) requiring visibility among various pieces of information displayed on a narrow screen of the mobile communication terminal 100 is output through the detachable watch module 300 mounted on the terminal cradle 200. Can be. Therefore, since the road guidance information displayed on the detachable watch module 300 mounted on the terminal cradle 200 does not need to be displayed on the screen of the mobile communication terminal 100, the screen area of the mobile communication terminal 100 can be optimized. I can.

On the other hand, the second form according to whether a short-range wireless communication connection (Bluetooth connection) is performed is a second case in which road guidance information is not received from the mobile communication terminal 100 because the short-range wireless communication is not connected with the mobile communication terminal 100. to be. In this second case, regardless of whether or not the mobile communication terminal is mounted, the cradle control unit 270 may perform the terminal non-interlocking mode through the detachable watch module 300.

In the terminal non-interlocking mode, data communication is disconnected because a short-range wireless link is not connected between the terminal short-range wireless communication unit 160 of the mobile communication terminal 100 and the cradle short-range wireless communication unit 220 of the terminal cradle 200. In the terminal non-interlocking mode, the cradle control unit 270 may transmit and output GPS guide information calculated by the cradle GPS module 230 to the detachable watch module 300 mounted on the terminal cradle 200.

Here, the GPS guide information is guide information including a distance from a current location to a facility (eg, a surveillance camera), a current speed, a current time, and a current location. That is, the GPS guide information refers to information that can be generated using GPS location information, and indicates how far the location of the surveillance camera of the vehicle in which the mobile communication terminal 100 is mounted is from the current location of the vehicle. Distance guidance information, current speed, time, etc. calculated using GPS location information may be included. In order to guide the distance to the enforcement camera among GPS guide information, the terminal cradle 200 stores location information of the enforcement camera. The location information of the surveillance camera may be updated when interlocked with the mobile communication terminal. For reference, FIG. 8 is a diagram showing a state in which GPS guide information is displayed on the detachable watch module 300 as a terminal non-interlocking mode. The GPS guide information may correspond to a distance from the current location to the enforcement camera, as shown in FIG. 8A. Here, the enforcement camera is a camera that controls whether the driving speed of a vehicle or the like exceeds the speed limit. In addition, as shown in Fig. 8(b), the current speed, the current time, and the current position may be displayed.

As a result, when the short-range wireless communication is not connected and the terminal operates in the non-interlocking mode, as shown in FIG. 11, regardless of the mobile communication terminal, only the GPS guide information generated by the terminal cradle 200 is output and separated. It transmits wirelessly to the watch module 300. That is, FIG. 11 (a) is a diagram showing a state in which GPS guide information indicating the distance to the enforcement camera and the regulated speed is displayed on the detachable watch module 300 when the mobile communication terminal 100 is not connected with Bluetooth, FIG. 11(b) is a diagram showing a state in which GPS guide information indicating a current speed, a current time, and a current location is displayed on the detachable watch module 300 when the mobile communication terminal 100 is not connected to Bluetooth.

Meanwhile, when operating in the terminal non-interlocking mode, the cradle control unit 270 may generate GPS guide information by using the cradle-calculated GPS location information or the terminal-calculated GPS location information. When terminal-calculated GPS location information is received from the mobile communication terminal 100, GPS guide information may be generated using the terminal-calculated GPS location information. If the GPS module of the cradle is implemented as a low-cost product in order to reduce the manufacturing cost, the GPS location information calculated by the terminal is more accurate than the GPS location information calculated by the cradle. It is to create guidance information. However, if the GPS location information calculated by the mobile communication terminal 100 is not received, GPS guide information may be generated using the GPS location information calculated by the cradle. When the short-range wireless communication connection with the mobile communication terminal 100 is not established, GPS guide information is generated by using the GPS location information calculated by the cradle itself. For reference, when generating GPS guide information, a distance to a specific facility may be calculated based on the current location by using a facility location database storing data on the facility location point. In addition, when the terminal cradle 200 cannot receive GPS data from a GPS satellite, the mobile communication terminal 100 may request and receive terminal-calculated GPS location information, and use this to generate GPS location information for the cradle.

On the other hand, the terminal cradle 200 may include an alarm lamp 260 that lights up in a different lighting form according to a terminal interlocking mode, a terminal non-interlocking mode, and whether or not a speeding has occurred. For example, in the terminal interlocking mode, the blue light may be lit, and in the terminal non-interlocking mode, the red light may be lit. In addition, the alarm light 260 may warn a user by performing on/off blinking when the vehicle speed exceeds the limit speed. The vehicle speed is calculated from GPS location information, and when the vehicle speed exceeds the speed limit on the current road, a flashing operation is performed to warn the user. For example, if the current speed of the vehicle is at a constant speed that does not exceed the speed limit, the alarm lamp 260 is displayed in green, and if the current speed of the vehicle exceeds the speed limit, the alarm lamp 260 is displayed in red. Flashing operation can be made.

Meanwhile, the terminal cradle 200 includes a power supply unit 240 for providing driving power to the cradle short-range wireless communication unit 220, the cradle GPS module 230, and the cradle control unit 270, respectively.
