Description

Method for sharing navigation data between heterogeneous devices using communication and navigation system {for method sharing navigation data between different kind devices using communication and navi-interlocking system therefor}

The present invention relates to a navigation device, and more particularly, a communication device that connects a navigation device or a GPS terminal with another device through communication so that other devices can use data (GPS data, navigation data, navigation information, etc.) of the navigation device or GPS terminal. The present invention relates to a navigation data sharing method and a navigation linkage system between heterogeneous devices.

In general, the navigation device or GPS terminal is composed of a software unit 10 and a hardware unit 20 as shown in FIG. The software unit 10 of the navigation device or the GPS terminal includes an application unit 11 and a data unit 12. Since the GPS terminal is usually a form in which there is no display unit of the navigation device, that is, a terminal incorporating navigation data, the GPS device is included in the navigation device unless otherwise specified herein. That is, for convenience of explanation, unless otherwise specified, the term "navigation device or GPS terminal" is collectively referred to as "navigation device". The performance of the navigation device 1 depends largely on the performance of the hardware unit 20 including the GPS 23, in particular the processing power of the central processing unit (CPU) 21, the size of the memory 22 and the graphics. It is affected by the presence or absence of a dedicated chip. In order to lower the price of the navigation product, it is necessary to optimize and develop the specifications of the hardware as much as possible, but if the hardware is developed at the lower specification with the price as the priority, the performance of the navigation function may be degraded and the satisfactory navigation cannot be realized.

On the other hand, the existing navigation device is a single product to implement only the navigation function, so if the performance of the hardware is not improved, it is impossible to implement the improved navigation and the life of the product is limited. In addition, even if you want to add a navigation function, it is impossible to implement because of the limitation of hardware performance. For example, to implement 3D maps requires high-performance hardware. However, if the existing navigation is not a high-performance hardware capable of implementing 3D, the addition of practical navigation functions is very limited.

In addition, the existing navigation device or GPS terminal is installed in most vehicles because of its characteristics, so to update the product or add new content, the device must be detached and operated. The existing navigation device has a screen size of 3.5 inches depending on the product. It is too small to operate. In addition, the memory size of the existing navigation device is limited, making it difficult to extend the function, and the method for upgrading is also complicated.

On the other hand, mobile phones equipped with the recent GPS-enabled navigation function can download and use various data (e.g., satellite maps and traffic information) through wireless broadband Internet access technology such as Wi-Fi (Wireless Fidelity). However, when using the navigation data, it is difficult to use the call function of the mobile phone, and there is a problem that cannot be used as a mobile phone when calculating the route.

On the other hand, with the development of wireless communication technology, a terminal device having a high performance with a built-in wireless communication function is widely used. Such terminals are representative of PMP, notebook, UMPC, smart phone, PSP, PDA, etc. Although the purpose of these terminals is different, they have a specification that can be used as a navigation terminal with high hardware performance and excellent operability. It is not used for its own purpose because it does not have GPS built in to perform the data or no data is provided for navigation.

The present invention has been invented to solve the above problems, a device capable of a navigation function such as a navigation device or a GPS terminal, and other devices to connect the other device by communication to other devices actively to the data of the navigation device or GPS terminal An object of the present invention is to provide a navigation data sharing method and a navigation linkage system between heterogeneous devices using communication.

In addition, another object of the present invention is to share navigation data between heterogeneous devices using communication that allows the navigation function to be used with high performance in devices that have excellent hardware performance but do not have navigation data and thus cannot be navigated (for example, portable devices such as notebook computers). The present invention provides a method and a NAD interlocking system.

In a preferred embodiment of the present invention, when the navigation link device has already downloaded and used the navigation data from the navigation device and connected with another new navigation device, a version of the navigation data previously stored Is compared to the data version for navigation of the new navigation device, if all or part of the data of the new navigation device is the latest data, delete the existing data and download the latest data items from the new navigation device to bring the data for navigation to the latest version. If the data for navigation of all or part of the newly connected navigation device is lower than the data of the navigation link device, the data of the navigation link device is updated. And all the devices connected by the ever sent to the device used to be updated to always keep the navigation data for the same date.

In the preferred embodiment of the present invention, in order to perform a normal navigation function in the navigation link device in order to prevent illegal use of the navigation data, only after authentication is successful after authentication through communication with a navigation device connected at initial startup. Use the downloaded navigation data.

According to the navigation data sharing method and navigation interworking system between heterogeneous devices using the communication according to the present invention, since the navigation device can be operated in a link device with a large screen, the operation of the navigation device provided with a small size screen is improved.

According to the navigation data sharing method and navigation interworking system between heterogeneous devices using the communication according to the present invention, the navigation device can be a device that can not receive GPS data.

According to the navigation data sharing method and navigation interworking system between heterogeneous devices using the communication according to the present invention, since a single navigation device and a plurality of link devices can share a plurality of navigation data, the driving range of the navigation data is expanded. .

Hereinafter, a preferred embodiment of a navigation data sharing method and system between heterogeneous devices according to the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, when it is determined that detailed descriptions of related well-known technologies or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be made based on the contents throughout the specification.

First, a navigation device or a GPS terminal applied to the present invention is preferably a navigation device or a GPS terminal equipped with a communication module that enables communication with an existing navigation device or a GPS terminal. In some cases, a mobile phone having a built-in GPS and performing some navigation functions may also be a navigation device in the present invention. In addition, the navigation link device or link device applied to the present invention is preferably hardware that is higher than the hardware performance of the navigation device (for example, a laptop computer, ipod touch MP4 player, PDA, PMP, PSP, DS, electronic dictionary, mobile phone, etc.) However, these devices are electronic devices that are not equipped with a GPS receiver and cannot receive GPS data and cannot generate navigation data and information. In the embodiment of the present invention, the navigation device or the GPS terminal operates as a kind of master device, and the link device is used for communication (for example, wireless communication such as WiFi, WIBRO, Bluetooth, and wired communication such as serial communication). It can be viewed as a client device that is connected to a navigation device or a GPS terminal to perform a high-performance navigation function by using various data transmitted from the navigation device or the GPS terminal.

2 to 4, in the navigation data sharing method between heterogeneous devices using the communication according to the present invention, the navigation device 100 first communicates with the communication module 230 of the navigation link device 200. The communication module 130 corresponding to the communication module 230 is installed (S10). The navigation link device 200 is provided with navigation application software (or navigation software) that enables the link device 200 to perform navigation using navigation data such as GPS data transmitted from the navigation device 100. (S20).

With the communication module 130 and the application software installed as described above, the navigation device 100 or the GPS terminal starts the communication module 130 to communicate with the communication module 230 of the navigation link device 200 ( S100). Alternatively, the navigation software can be integrated to perform communication functions. The communication module 230 of the link device 200 may be, for example, a communication module for performing wireless communication such as WIFI, WIBRO, Bluetooth, or wired communication such as serial communication, and communication of the navigation device 100 or the GPS terminal. As described above, the module 130 is a module capable of communicating with a communication module installed in the link device 200. For example, when the communication module 230 of the navigation link device 200 performs WiFi, the communication module 130 of the navigation device 100 may include a router and an access point (AP) function. It will be apparent to those skilled in the art. On the other hand, when a mobile phone that is equipped with a GPS that can perform a navigation function is used as the navigation device of the present invention, since there is a module for communicating with the mobile phone already, there is no need to install a separate communication module to those skilled in the art Will be self explanatory.

Meanwhile, the application software installed and activated in the navigation link device 200 may be downloaded and installed free or for a fee through the Internet in the form of freeware. The application software may be uploaded to a website or the like for free or paid for use by the operator who manufactures and sells the navigation device 100 to increase the value and utility of the navigation device 100, that is, to spread widely. Preferably, in some cases, it can be distributed free or paid in a recording storage medium such as a CD.

The reason why the manufacturer of the navigation device 100 distributes and uses navigation application software for free or for a fee as described above is not only a communication function but also a notebook, PDA, and PMP equipped with the highest performance hardware. In order to enable users who use portable electronic devices such as mobile phones and game consoles to use the navigation data provided by the navigation device 100 or the GPS terminal by purchasing the navigation device 100 or the GPS terminal at a low price. In other words, the manufacturer or seller of the navigation device 100 or the GPS terminal distributes the application software for free or for a fee so that the navigation device 100 or the GPS terminal can be used by more users.

When the communication module 130 and the application software are installed in each of the devices 100 and 200 through the steps S10 and S20, the user may substantially share the navigation data between the heterogeneous devices and the application software. Start (S100) (S200). When the communication modules 130 and 230 and the application software of each of the devices 100 and 200 are activated, the navigation device 100 or the GPS terminal and the navigation link device 200 may be substantially connected to each other. When communication is connected between both devices (S300), the navigation device 100 or the GPS terminal transmits data and information necessary for navigation to the link device 200, and the link device 200 starts the application software. The navigation apparatus 100 receives data and information necessary for navigation from the navigation device 100 or the GPS terminal (S400).

3 and 4, the navigation system using communication according to the present invention includes a navigation device 100 or a GPS terminal that receives GPS data and generates various data required for navigation; And a navigation link device 200 having a hardware having higher performance than that of the navigation device 100 or the GPS terminal and including a communication module 230 capable of communicating with the navigation device 100 or the GPS terminal. In the present invention, the navigation device 100 or the GPS terminal is provided with a communication module 130 for communication with the navigation link device 200. The navigation link device 200 installs application software (or navigation software) for performing a navigation function by using a download or storage device (CD, DVD, SD, etc.).

The operation of the navigation data sharing method and the navigation system between heterogeneous devices using the communication according to the present invention configured as described above will be described with reference to FIGS. 2 to 9.

First, the synchronization between the navigation device 100 or the GPS terminal and the navigation link device 200 will be described. In the present invention, since the navigation device 100 or the GPS terminal serves as a kind of master, and the navigation link device 200 serves as a kind of client, in the present specification, for the convenience of description, the navigation device 100 or the GPS terminal is used. The name is used mixed as the master device, and the navigation link device 200 is used as the client device.

3 to 5, an example of using an access point (AP) function for a synchronization operation between a master device 100 (navigation device or GPS terminal) and a client device 200 (navigation link device) is as follows. . FIG. 5 is a reference diagram for explaining a synchronizing operation of the present invention, and the names of specific components constituting the software 10 are used as the original names commonly used by those skilled in the art for convenience. In Fig. 5, reference numeral 10 'is navigation software (application) distributed free of charge.

For synchronization between two devices, when the user activates the navigation software 10 of the master device 100, the navigation software 10 selects an access point (AP) mode so that the user can select a synchronization mode or a navigation only mode. Displays the screen and the navigation mode selection screen on the screen. Or, it can automatically execute AP communication mode and display connectable devices. When the user selects the AP mode, the navigation software 10 searches for the connected device. If the connected device is found, the navigation software 10 displays a popup to the user to display the found device name. When the user selects the desired navigation link device 200 from the searched device name, the navigation software 10 communicates with the navigation link device 200 through the communication module 130 to maintain the communication state in a synchronous state. If no device is found, a pop-up message such as "No device is connected" is displayed on the screen, then the AP mode is terminated, and the navigation alone mode is used.

On the other hand, the navigation link device 200 also activates the navigation software 10 'downloaded and installed for synchronization with the navigation device 100. The navigation software installed on the link device does not have the data necessary to perform the navigation and therefore cannot perform its normal function. When the navigation software 10 ′ is activated in the navigation link device 200, the navigation link device 200 also pops up a communication mode (eg, WiFi mode) for communication connection with the navigation device 100. When the user selects a communication mode, the navigation software 10 'searches for a communication connectable AP and displays the communication connectable search device name. When the user selects the navigation device 100 in the searched device name, the navigation software 10 ′ communicates with the navigation device 100 through the communication module 230 to maintain the communication state in a synchronous state. If no device is found, a pop-up message such as "No device connected" is displayed on the screen, then the communication mode is terminated, and the device mode is used.

Next, a data transmission / reception operation between the two devices 100 and 200 will be described with reference to FIG. 6. When the navigation device 100 and the navigation link device 200 are communicatively connected as described above, the navigation device 100 as the master device and the navigation link device 200 as the client device confirm the communication. After confirming the communication, the navigation device 100 transmits a notification for data transmission to the navigation link device 200. When the data transmission confirmation request transmitted from the navigation device 100 is received by the navigation link device 200, the navigation link device 200 displays a popup for approving data transmission on the screen. When the user selects the approval button displayed on the pop-up, the navigation link device 200 transmits a data transmission approval message to the navigation device 100.

When the navigation device 100 receives the data transmission approval message transmitted from the navigation link device 200, the navigation device 100 transmits data necessary for navigation to the navigation link device 200. As shown in FIG. 4, data transmitted to the navigation link device 200 may be classified into search data D1, map display data D2, route calculation and guidance data D3, and the like. Alternatively, data can be sent to a single compressed data file for efficient data transfer, and then decompressed and re-converted into a data structure for navigation.

The navigation apparatus 100 preferably displays a data name, a transmission progress status, and the like on the screen during the transmission of the navigation data, and deactivates all menus in order to prevent screen manipulation. Meanwhile, the navigation device 100 preferably requests information of the data transmitted to the navigation link device 200 in order to confirm whether the data transmission is successful, and terminates the transmission mode if the data transmission is successful. After the data transmission is completed, the navigation device 100 may check whether there is an abnormality in the embedded data.

When data is transmitted from the navigation device 100, the navigation link device 200 stores the transmitted data in the internal memory 222 (FIG. 3). When the data transmission is completed, the navigation link device 200 transmits the transmission completion information to the navigation device 100 side, and also notifies the transmitted data information requested by the navigation device 100 side. When the transmission of the necessary navigation data is completed, the navigation link device 200 reads the stored navigation data and performs a map display.

As described above, even though the navigation data (e.g., search data, map display data, route calculation and guidance data) required for map display has been received and stored, the navigation link device 200 is required for substantial navigation as shown in FIG. 7A. Data on the current coordinate value, that is, GPS data should be received from the navigation device 100 in real time. That is, if GPS data is not received from the navigation device 100 in real time, only a screen such as [before GPS interworking] as shown in FIG. 7b is displayed, and [after GPS interworking] as shown in FIG. 7c. In order to display the same screen, GPS data must be received from the navigation device 100 in real time. Therefore, the navigation link device 200 configures a screen for displaying a map by reading the stored navigation data, and receives the GPS data 12a in real time from the navigation device 100 to perform the actual navigation based on the current coordinate values. .

Thus, according to the present invention, the navigation link device 200, which is a client device having high-performance hardware, is a data required for navigation, and includes GPS data 12a, search data D1, map display data D2, and a route. The calculation and guidance data D3 may be received from the navigation device 100 having low hardware performance to implement navigation with higher performance than the navigation device implemented in the navigation device 100. Therefore, it will be apparent to those skilled in the art that only navigation data is shared and navigation software can be developed and used separately from the master device to implement high-performance navigation, and it is not necessary to maintain the same software version as the master navigation.

On the other hand, according to the present invention, since communication between each other is possible through the communication module, it is possible to operate two devices at the same time in the communication synchronization state after starting the navigation software, which will be described as follows.

Referring to FIG. 8, when the navigation device 100 and the navigation link device 200 select a synchronous interlocking mode in a state in which the navigation link apparatus 200 is connected and synchronized in communication as described above, each device is converted into a synchronous interlocking mode state, and thus the navigation is performed. When the menu is operated in the device 100 or the navigation link device 200, the menu information is transmitted to another device to perform the same operation. To this end, unique command values of each menu can be unified with each other, and when each menu operation is executed, the same operation can be automatically performed by transmitting the command value to another device connected through communication. Therefore, by using such a synchronous interlocking mode, one device can be used as a remote control of the other device because the device can be operated using a device having a large screen or an easy to operate device according to the situation. In addition, during the menu operation, preferably, data communication such as GPS can be temporarily stopped to adjust the menu operation smoothly.

On the other hand, in the navigation function, the route calculation from the origin to the destination is largely dependent on the hardware performance. When the hardware specification of one device is high, the route calculation is performed on the side with the good hardware performance. It is possible to reduce the path calculation time by transmitting to another device, and since the path calculation data is the same, two devices can provide the same guidance at the same time. That is, according to the present invention, since the hardware performance of the navigation link device 200 is good, the starting point and the destination are set here to perform the route calculation. When the path calculation is completed in the navigation link device 200, the calculated path calculation data is transmitted to the navigation device 100. When the calculated route calculation data is transmitted to the navigation device 100, the navigation device 100 displays the transmitted route calculation data on the screen. Once the route calculation data has been made available to the navigation device 100, the navigation device 100 generates GPS data providing the current coordinate values and transmits the GPS data to the navigation link device 200, thereby navigating itself as well as the navigation link device 200. The same navigation can also be performed. That is, the path calculation may be performed by the navigation link device 200 having a high hardware speed, thereby improving navigation performance.

In addition, in the case of the existing navigation device, in order to use traffic information or additional content, it was possible to use information by connecting a server with a built-in communication module or installing a separate receiving device. However, such a connection device is inevitable in price increase and can be used only in an expensive navigation device. Therefore, when utilizing the present invention, when linking a mobile phone-type navigation link device with a built-in wireless communication function, the link device downloads various information (traffic information, news, securities, etc.) from a server and transmits it back to the navigation device. By doing so, it is possible to share the same information without increasing the price of the navigation terminal.

Referring to Figure 10, a method of sharing traffic information in detail as follows.

In order to provide traffic information, the basic navigation device 100 receives traffic information data by incorporating a dedicated receiver into the navigation device 100 or by directly connecting it. However, nowadays, communication terminals (smartphones, iPhones, mobile phones, etc.) supporting various wireless Internet are spread, so when used as a navigation link device 200, the traffic information navigation by connecting to the traffic server 300 through the wireless Internet The link device 200 may download and use the downloaded traffic information, and the downloaded traffic information may be transmitted to the navigation device 100 so that two vehicles may simultaneously use the traffic information. In this case, one is for checking traffic information, and the other is useful for using information by using traffic information as a separate function such as a route guidance function. By displaying various information on the two devices as described above, the received traffic information can be quickly used for driving.

The order of sharing traffic information is as follows.

When the navigation link device 200 connects to the server 300 using the wireless Internet network (S101), the server 300 performs user authentication. If the user authentication is finished, the server transmits the traffic information requested by the navigation link device 200 (S102). The navigation link device 200 displays the data on the map using the data transmitted from the server 300 or uses it in the navigation, and transmits the traffic information received to the navigation device 100 (S103). The navigation device 100 utilizes the traffic information data transmitted from the navigation link device 200 in a desired mode (screen is a simple display type).

Referring to FIG. 11, the map updating method will be described in detail as follows.

In the case of the navigation data of the existing navigation device 100 to update, it is possible only by manually changing the data inside the device. For example, in the case of a DVD navigation device, a new DVD must be purchased, and in the case of an HDD-type navigation device, it is inconvenient to remove data from a hard disk and update data in a dedicated device. In the system of the present invention, when the navigation link device 200 supporting the wireless Internet is connected, update data is downloaded from the server 400 via the wireless internet, and the data is transmitted back to the navigation device 100 so that the navigation data can be easily transferred. You can update it. In case of wireless internet, unique phone number is assigned to prevent illegal copying of map data. When using the updated data of master, check the phone number of link side navigator to start and prevent illegal copying of data. can do.

The detailed flow of the map updating method is as follows.

Referring to FIG. 11, the navigation link device 200 connects to the map data server 400 using a wireless internet network (S111). When the navigation link device 200 is connected to the server 400, the server 400 performs user authentication and transmits the latest cost data to the navigation link device 200 (S112). The navigation link device 200 implements navigation using the data transmitted from the server 400, records its mobile phone number information to the master side navigation device 100, and transmits navigation data (S113). The navigation device 100 updates the data with the data transmitted from the navigation link device 200 and requests a phone number from the navigation link device 200 while activating the navigation using the updated data (S114). When the navigation link device 200 receives a request for a phone number from the navigation device 100, the navigation link device 200 transmits its own phone number to the navigation device 100 (S115). If the phone number received from the navigation link device 200 and the phone number recorded in the data match, the navigation device 100 normally activates the navigation using the data.

In addition, according to the present invention, when the navigation link device 200 has already downloaded the navigation data from the navigation device 100 and is in use, when the navigation link device 200 is connected to another new navigation device, the navigation device has been stored previously. Compare the version of the data for the new navigation device with the data version for the navigation device, and if all or part of the data of the new navigation device is the latest data, delete the existing data and download the latest data item from the new navigation device to download the data for navigation. Update to the latest version or, conversely, if the navigation data of all or part of the newly connected navigation device is lower than the data of the navigation link device, the data of the navigation link device is transferred to the navigation device. By transmitting, updating and using it, all connected devices always maintain the same latest version of navigation data.

In addition, to perform a normal navigation function in the navigation link device 200 in order to prevent illegal use of the navigation data, it is downloaded only when authentication is successful after authentication through communication with the navigation device 100 connected at initial startup. Use navigation data.
