The readable recording medium is a _flash drive (Flash Drive). The method of downloading through the social community website: The dangerous road section database 13 is also used for at least one website information storage input by the user. The website information includes a website address for downloading at least one dangerous section of the website, and a category information corresponding to the website. The category information indicates that the dangerous section of the dangerous section of the website corresponds to one of the car modes 'one locomotive mode or one bicycle mode. That is, the information of the category corresponding to the website is used to distinguish the dangerous section data of the website downloaded from the website, which is one of the car mode, the locomotive mode or the bicycle mode. The data receiving unit includes a transceiver module (not shown) connectable to the website and downloading the dangerous section data of the website from the website. The transceiver module stores the data in the dangerous section database 丨3. At least one of the dangerous sections of the information is the dangerous section of the website. In the preferred embodiment, the website is a community website for car owners that is related to the car 'locomotive or bicycle' and the website allows the riders to add dangerous sections of the website. The 7 201237816 transceiver module can be connected to the website through a wired network or a wireless network, but the details of the connection are not the focus of the present invention, and therefore will not be described here. It is worth mentioning that the dangerous sections of the website within the website are also classified according to the region, for example, by county and city. Therefore, the transceiver module can also download the dangerous section data of the website from the website through the wireless network according to the current location and the website information. That is to say, the transceiver module can download the relevant dangerous section data of the website along with the location where the navigation device 1 is located. For example, if the current location of the navigation device 1 is in Taipei City, the transceiver module downloads the dangerous section data of the website related to the website in Taibei City according to the website information of the website information. The processing unit 15 is connected to the global positioning system receiving unit, the data receiving unit 12, the dangerous link database 13' and the map database 14, respectively. In the following, when the road segment warning function of the navigation device 1 is operated, the relationship between the units is further explained. First, the processing unit 15 is configured to perform positioning according to the global positioning system satellite signals to calculate a positioning position corresponding to the location of the navigation device ,, and generate a suggested path according to the positioning positions. The processing unit 15 can be operated in one of a car mode, a locomotive mode and a bicycle mode, and the switching or decision between the operating modes of the processing unit 15 can be performed automatically or manually. The output unit 16 is connected to the processing unit 15 and is used to display the electronic map data and the suggested path 8 201237816. In the preferred embodiment, the processing unit & 15 is based on the The movement state of the position calculates a speed, and refers to one of the preset speeds in the speed comparison table (see Table 1), and switches the operation mode to one of the vehicle mode, the locomotive mode and the bicycle mode. . That is, the processing unit 15 determines, based on the current speed of the navigation device i, whether the (four) communication tool is the automobile, the locomotive, or the bicycle to operate in the corresponding vehicle mode, the locomotive mode, or the bicycle mode. Preset speed operation mode Preset speed 1 Car mode Preset speed 2 Locomotive mode 'Preset speed 3 Cycling mode, "A road feature of the male port, the position of the battle position, operation (4) Car m locomotive mode and skip mode, For example, if the road corresponding to the location is corresponding to the highway, the processing unit 15 will automatically decide or = switch to operate in the car mode; If the road special corresponds to the lane, then the processing unit 15 will automatically decide or switch: in the locomotive mode; if the corresponding position is = in the riverside park - single lane, then The processing unit 15 automatically switches to or operates in the bicycle mode. ', Manual mode: In the preferred embodiment, the operation mode of the processing list a 15 can also be 201237816 =: through the user interface 18 (For example, keyboard, mouse, touch unit) Manually set-vehicle mode, operate in "fly, 4 locomotive mode or the bicycle mode" - 2::! When the tool is the car, the user Permeable The user mode: the vehicle mode is the car mode, so that the process 2 is the car mode; similarly, when the vehicle is the locomotive, the locomotive module t can set the mode of the vehicle to the 'through the user interface 18 (4) The processing unit 15 operates in the locomotive mode; similarly, when the bicycle is in use, the user can use the user interface to "turn the tool mode into the bicycle mode" to operate the processing unit 15 in the bicycle mode. It is to be noted that each dangerous road segment data corresponds to at least one of the car mode, the locomotive mode and the bicycle mode. _ Next, when the processing unit 15 operates in the car mode, the process:疋15 will obtain the data of the dangerous road section corresponding to the automobile mode from the dangerous road section database 13; when the processing unit 15 operates in the locomotive mode, the management order 15 will obtain the corresponding locomotive mode from the dangerous section database 13. The dangerous section data; t when the processing unit 15 operates in the bicycle mode, the single unit 70 15 will obtain the corresponding single =! dangerous section data from the dangerous section database 13. The processing is further judged according to the dangerous section of the dangerous section data obtained from the && database, and the negotiation path. That is, the processing unit determines whether the suggested path crosses the corresponding navigation. The dangerous section interval of the operation mode of the device in time is 201237816. Finally, the user can also select the _ dangerous treatment mode when the suggested path crosses the dangerous section sections through the user interface 18.... See FIG. 2, for example, assume that the processing unit 15 has automatically operated in the car mode according to the speed. When the user selects the risk processing mode to be the avoidance mode, the processing unit 15 also according to the risk. The link section 164 and the positioning position generate a avoidance suggestion path 163 to update the suggested path and perform related output through the output unit 16. The avoidance suggestion path 163 does not traverse the dangerous link section 164 corresponding to the suggested route 163 to allow (4) to avoid the dangerous section section (6). In this example, the dangerous section interval 164 is the section being defended. The output unit 16 includes a display 161 and a speaker 162. The avoidance suggestion path 163 is associated with the display 161 for related display. That is to say, 'the avoidance suggestion path 163 generated by the bean when the material element 15 is operated in the vapor phase type is traversed through the dangerous section section 164 of the car mode corresponding to the use order; the unit 15 operates on In the locomotive mode, the avoidance suggestion path 163 generated in the avoidance mode does not cross the dangerous link section 164 corresponding to the locomotive mode of the navigation device i; when the processing unit: is in the bicycle mode The avoidance path # 163 generated in the avoidance mode does not cross the dangerous link section 164 corresponding to the bicycle mode in use by the navigation device 1. According to Fig. 3, Fig. 3, for example, assumes that the processing unit 15 has been at risk == movably operating in the bicycle mode. When the user selects the risk mode as the alert mode, the processing unit 15 determines whether the suggested route generated by the 201237816 passes through the dangerous link sections corresponding to the bicycle mode in use by the navigation device. A warning signal is generated when the suggested path traverses at least one of the dangerous sections. That is to say, if the suggested path traverses at least one of the dangerous sections, the processing unit 15 generates the warning signal. The output unit 16 will output the warning signal correspondingly. In the preferred embodiment, the dangerous section is a section with a lot of pavements. The alert signal includes a visual effect 165 and an audible effect. The display $161 is used to rotate the visual effect 165 to enhance the alertness of the user through the text; the speaker 162 is configured to output the audible effect corresponding to the text content for the user to be alert.
