Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a global positioning technology, and more particularly to a navigation device and a navigation method. [Prior Art] The development of the Global Positioning System (GPS) is hosted by the US Department of Defense, involving the Ministry of Transportation, and transferring technology to civilian use. In recent years, it has been applied to navigation and positioning. /Bei J is a bit of a bad attitude and standard time and other related work. It is a navigation system that combines satellite and cable technology to provide precise positioning, speed and day-to-day. The application of GPS has been widely used in the current field. With the advancement of satellite technology, many GPS technologies and business opportunities have developed rapidly. GPS was limited to military units in the early days, and its purpose was for military purposes, such as warplanes, ships, vehicles, and personnel. , the accuracy of the target object, etc. Today, GPS Lu has been opened to the public for positioning. This technology combining space satellite and communication technology has been vigorously developed in the private market. In addition to providing accurate positioning, it is for speed and time. Directions and deviations can also provide accurate information, and the scope of application is quite extensive. GPS discs are full of unlimited business opportunities. With the development of global positioning technology, products derived from the application of food-ball satellite positioning technology have also come out, such as car navigation devices. Referring to Fig. 1, a conventional car navigation device 1 is provided in a car. The vehicle navigation device includes a food ball positioning module 11, a storage module 12, a display module 13, and a processing die cone I4. The global positioning module 11 200825376 can receive a plurality of global positioning signals 111 transmitted by a plurality of satellites, and calculate the global positioning signals 111 to a position coordinate 112 of the car navigation device 1 (automobile). The storage module 12 stores an electronic street map '121. The display module 13 is electrically connected to the storage module 12 and displays an electric sub-street map 121. The processing module 14 is electrically connected to the storage module 12, the global positioning module 11 and the display module 13, and the position coordinates 112 of the vehicle navigation device 1 (car) are indicated on the electronic street map displayed by the display module 13. 121 corresponding position, to facilitate navigation. # However, although the height indicator is also included in the global positioning signal, the accuracy of the height indicator is not quite accurate. Therefore, when the vehicle travels on an elevated road (planar road) overlapping with a plane road (elevated road), the height difference between the plane road and the elevated road falls within the error value of the height index, so that the vehicle navigation device 1 often The wrong location data will be displayed, or a new path will be re-planned. SUMMARY OF THE INVENTION It is an object of the present invention to provide a navigation device in which a level is placed in a navigation device to know whether there is a gateway to enter (leave) a non-planar road and to plan and broadcast the route correctly or in a timely manner. It is still another object of the present invention to provide a navigation method that can be correctly displayed on a map material when a user enters (leaves) a gateway of a non-planar road, and is displayed and voiced. The present invention provides a navigation device that receives a satellite positioning signal. The navigation device includes a global positioning module, a horizontal detection module, a data 7 200825376 library, and a central processing module. The above-mentioned global positioning module receives the satellite positioning signal, and obtains and outputs the current position data after decoding the satellite positioning signal. The horizontal detection module described above selectively generates and outputs a 'tilt signal. The above database is stored with map data. The central processing module receives the current location data, the map data and the tilt signal, and determines whether the current location data has a non-planar road within a preset range on the map data when receiving the tilt signal. Wherein, when the central processing module determines that the current location data has a non-planar road within a preset range on the map data, a non-planar road notification message is output. The present invention further provides a navigation method suitable for use on a navigation device. The navigation method includes first receiving a satellite positioning signal. Secondly, after decoding the satellite positioning signal, a current position data is obtained and output. Then, a tilt signal is selectively generated and output. Then, when receiving the tilt signal, it is determined whether the current location data has a non-planar road in a preset range on the map data, and when the current location is determined, the data is in the preset range on the map data. On a flat road, the output ® is a non-planar road notification message. The present invention is based on the configuration of a level on the navigation device so that when the vehicle enters (leaves) the gate of the non-planar road, it will be known from the angle of inclination of the level and thus the navigation device will be informed of the correct position of the vehicle. That is, the navigation device can be made to more clearly distinguish whether the vehicle is on a flat road or a non-planar road, thereby providing a correct voice indication or planning a correct new path. 8 200825376 [Embodiment] The guide of the embodiment will be described below with reference to the related drawings.仏 Referring to FIG. 2, JL gives + / six jobs _ ^ ^, 曰 η a preferred embodiment of a V-aviation device of the circuit of the circuit 闰 ll _ 峪 峪 块 block diagram. The navigation device 2 includes a global positioning module 21, a database 22, a display λ package, a 琢疋 埤Ζ display unit 23, a horizontal measurement module 24, a speaker module 25 and a central processing module. 2, , , , ' r / , a , u 26 , wherein the navigation device 2 can be, for example, a personal digital assistant (Pda), a smart phone / a smart phone or a personal computer (pers 〇ή.p Λ, S〇nal C〇mPuter referred to as PC), or any other electronic product with a croquet positioning system. The global positioning module 21 receives the satellite positioning signal and decodes the satellite positioning signal to output the current position data. The global positioning module 21 includes an antenna unit 211 and an arithmetic unit 212. The antenna unit 211 receives and outputs a satellite positioning signal. The operation unit 212 is electrically coupled to the antenna unit 211, and receives and decodes the satellite positioning signal to output the current position data. In a preferred embodiment of the present invention, the decoding operation performed by the operation unit 212 on the satellite positioning signal may be, for example, first, after the satellite positioning signal is amplified by an active low noise amplifier circuit (LNA), and then utilized. The filter filters out the noise to obtain the satellite positioning signal of the National Marine Electronics Association (NMEA) agreement. Then, from this data, the current location data containing the longitude and latitude is obtained. 9 200825376 In a preferred embodiment of the invention, the satellite positioning signal is, for example, a satellite number including (1) longitude (2) latitude positioning completion code (4) using effective satellite number (5), and elevation angle, direction Corner, receive. Signal strength (6) Satellite azimuth (7) Height (8) Relative displacement Displacement - Velocity (9) Relative displacement Displacement direction angle (1 〇) Date (n) utc Time (12) DOP error reference value (13) Satellite status And receiving status. The horizontal tilting module 24 selectively generates and outputs a tilt signal. The level debt testing module 24 includes a level 241 and a detecting unit 242. In the brewing, the level 241 generates a tilt angle according to the motion of the current navigation device 2 (i.e., the tilt angle formed by the horizontal reference plane when the vehicle travels on the slope section). The detecting unit 242 is electrically coupled to the level 241, and the metering unit το 242 detects the level 241 without interruption, so that the tilt angle is greater than the built-in angle of the Xiaohan angle. Output a tilt number. In the preferred embodiment of the present invention, the preset time and the preset angle are - (4) if the manufacturer of the navigation device 2 is set at the time of manufacture. The pre-$ angle can be, for example, the minimum angle or average value of the elevated roads and highways in Taiwan, and the preset time can be, for example, the vehicle passing through the elevated roads and highways within the speed limit. The minimum time required for the slope of the gateway, but not limited to this. In the preferred embodiment of the invention, when the level 211 is enabled, the water level of the Liangping 211 is compared with a horizontal reference point (which may be the water level stored when the built-in water is used for a long time). Correct. When the current gap between the water level and the station is within an error value (i.e., the vehicle 200825376 should be in a plane), the current water level is the new horizontal base # point. Conversely, 'When the gap between the current water level and the horizontal reference point is not the # inducement range value (that is, the vehicle should be on the slope), then the ground breaks the water level and changes the current water level to the horizontal reference point. When the gap is within the error value, the new level reference 2 is reset. ‘Continue to refer to Figure 2, this database 22 stores map data. The map information may be, for example, an elevated road or a highway, but not limited thereto. The central processing module 26 receives the current location data, the map resource and the tilt signal, and when the current location data is received, the current location #赏科 is marked on the map data. Next, the central processing module 26 determines whether the current supply data has a non-planar trajectory (flat road) or not within a predetermined range of the map data. When the central processing module 26 determines that there is a non-planar road (planar road) within the preset range of the current information on the map data, a non-planar road (planar road) notification message is output. In the preferred embodiment of the present invention, in order to enable the navigation device 2 to perform the navigation function more accurately, the tilt angle of the level can be used regardless of whether the vehicle is on the upper or lower elevated road, the south speed highway, or the like. It is known that we will enter (leave) elevated roads and highways in order to be able to connect with non-planar roads (planar roads). In the preferred embodiment of the present invention, as is familiar to those skilled in the art, the preset range is the distance between the gateway and the non-planar road or the flat road, but is not limited thereto. In this embodiment, the display module 23 is electrically coupled to the central processing unit 11 200825376 module 26, and receives and displays the non-flat, that is, the display module 23 displays a notification of ^ entering * (face) message. Message. Exhaustive) Non-planar road-ear board group 25 series electrically connected to the central processing and broadcasting non-planar roads (planar roads) to inform the news y 26, and the receiving group 25 will be voiced to enter (away) non; That is, the sound of the sound mode, please refer to Figure 2 and Figure 3, the message of complex and road. - In a navigation method of the preferred embodiment, in the second embodiment, the *navigation method is to first search for the defender in the sky at the start of the guide = °/2 = real device: 2 to at least 4 satellites After that, the antenna + ΓΡς i- - + and the antenna 兀 211 began to receive the satellite positioning signal (s3 〇 2) from the GPS star. Next, the arithmetic unit 212 performs a decoding operation on the satellite positioning signal (S304). Since the decoding operation has been described above, this is described. - After step S304, i.e., the operator unit 212 is positioned to dissipate the difference, the arithmetic unit 212 will obtain the current location information and output the directory location data to the central processing module %. Wherein, after receiving the current location data, the central processing module 26 marks the current poor material location on the map data (S306). After the voyage I is activated, the level 24 i will use the water level of the target level 211 to compare with the horizontal reference point and generate a tilt angle based on the comparison result. After the tilt angle is obtained, the level 241 outputs the tilt angle to the detecting unit 242 (S3〇8). 12 200825376 Referring to FIG. 3, when the detecting unit 242 receives the tilt angle, it is determined whether the tilt angle is greater than a preset angle or not (S310). When it is determined that the tilt angle is greater than a predetermined angle, then it is determined whether the tilt angle is greater than the preset angle is greater than a preset time? - When it is judged that the time when the tilt angle is greater than the preset angle is greater than the preset time, it is determined that the vehicle is, for example, in the upper or lower gate, thereby outputting a tilt signal to the central processing module 26 (S312) ). On the other hand, when it is judged that the time when the tilt angle is greater than the preset angle is less than the preset time #, it is judged that the vehicle does not have to go up and down the gate. Therefore, at this time, the navigation device 2 performs display and voice prompt according to the current road data. In the preferred embodiment t of the present invention, when it is judged that the tilt angle is smaller than a predetermined angle, it is not regarded as an upper gate or a lower gate. In this embodiment, when the vehicle where the navigation device 2 is located is to be gated by the plane road, the central processing module 26 determines that the current location data is on the map data according to the tilt signal and the map data. Within the range ^ there is a non-planar road or not (S314). Here, it is judged whether there is a non-planar road system within the preset range on the map data, and the slope of the flat road may be steep and the steep slope distance is long. Therefore, there is a mechanism in this design to separate. When it is judged that the current location data has a non-planar road within a preset range of the map data, the non-planar road notification message is notified to the user via the display module 23 and/or the speaker module 25 (S316). In this embodiment, when the vehicle in which the navigation device 2 is located is to be a lower gate of the non-planar road, the central processing module 26 determines that the navigation signal is based on the tilt signal 13 20U825376 and the map data. Set the tribute on the map data - the default range, Xing Xing (S318). s judged that 4,, there is a plane in the range of the road, Wei Wei, the material on the map data, a preset non-planar road notice 23 and / or speaker module 25 escape, this t (S320) . The configuration on the device - the navigation system and navigation method of the second navigation system will be based on the level of the navigation surface (four); = (in) two so that the navigation device knows the correct enemy of the vehicle: angle payment ': two
