Description of the Invention: [Technical Field] The present invention relates to a map information updating apparatus and method, and more particularly to a map information updating apparatus and method using GPS positioning technology. [Prior Art] The Global Positioning System (GPS) can provide a wide range of applications, such as resource survey and detection, navigation, location, geodetic, mapping, position dynamic information, and precise timing. The general user usually uses the position dynamic information function. By using the GPS signal receiver and the map database for calculation, the user's location can be displayed immediately. This is also the operation of the general map information update system (such as GPS navigation device). the way. However, the GPS technology currently used in the map information update system has the following disadvantages: (1) When the GPS navigation device is turned on, it needs to wait for a period of time to be able to operate normally. Generally, when the GPS navigation device on the market is powered on, it has to wait for tens of seconds to several minutes for the GPS navigation device to receive the GPS signal and the computing station & to display the updated map information. However, such a satellite reception process may cause inconvenience in use. (2) GPS signal reception is not easy, it will interrupt the continuous update of map information, and the ability of GPS signal to penetrate the shield is poor. Therefore, GPS signals cannot be received in buildings, tunnels, and underpasses, even when the weather is not good. It is also difficult to receive GPS signals when the clouds are dense. Therefore, the map is funded. The hole update system cannot continuously update the information. 110930 201022636 (3) The GPS navigation device consumes a lot of power and reduces the standby time of the handheld device. At present, the operating current of the GPS device is between 1 mA and 1 mA. Continuously turning on the map information update function will reduce the standby time of the handheld device (such as mobile phone or PDA) combined with the GPS navigation function, greatly reducing its practicability. . ..., only in summary, how to provide a more convenient and efficient map data update system and method has become an urgent problem to be solved. SUMMARY OF THE INVENTION In order to solve the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a map information updating apparatus and method for avoiding the problem that the map data cannot be quickly obtained due to poor Gps signal strength. Another object of the present invention is to provide a map information updating device and method, so that an electronic device that performs positioning processing by using a GPS signal does not continuously receive a GPS signal when the GPS signal is not good, thereby causing power consumption. To achieve the foregoing and other objects, the present invention provides a map information update device and method. The map information updating device is applied to an electronic device having a positioning function, the map information updating device comprising: a map database for storing map data; at least one positioning signal receiving module for receiving a clamp signal; GPS The signal receiving module is configured to receive a Gps signal, and the coordinate counting module is configured to calculate a coordinate of the positioning signal and/or the Gps signal corresponding to the map data; the map updating module is configured to The coordinate of the positioning signal or the GPS signal is updated on the map data; and the mode switching module is sent according to the Gps signal receiving state, the positioning signal receiving state, the electronic device power maintaining state, and/or the coordinate further 110930 201022636 new state. The trigger signal is sent to the map update module to switch the update mode of the map data. The map information updating method of the present invention comprises the following steps: (1) determining whether the received GPS signal is converted into coordinate information within a predetermined time, and converting into coordinate information, proceeding to step (5), not converting to coordinates The message then proceeds to step (2); (2) suspends receiving the GPS signal and switches to receive the positioning signal; (3) converts the positioning signal into coordinate information and updates the map data; (4) determines whether When the start of the gps signal is received, the process returns to step (1). If not, the process returns to step (3); and (5) the coordinate information of the GPS signal is updated to the map data. (1). The map information updating apparatus and method of the present invention solves the disadvantages of the conventional GPS navigation apparatus as compared with the prior art. The map information updating device of the present invention mainly operates by using at least one positioning signal receiving device in combination with a GPS navigation device. When the GPS navigation device is just turned on, the GPS signal is not received, or the GPS signal strength is too weak, the map information update device of the present invention updates the coordinates obtained by the positioning signal receiving module to the map, and the user does not Therefore, the timeliness of viewing map information is lost. When the user only needs simple map information, the power-consuming GPS navigation device can be turned off, and only the positioning signal receiving module can receive signals, convert coordinates and update map information. Therefore, the map information updating apparatus and method of the present invention greatly improves the convenience and immediacy of the user inquiring the map information, and solves the problem of inconvenience and power consumption of the conventional technology. [Embodiment] 110930 7 201022636 The following describes the embodiments of the present invention by way of specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the disclosure of the present specification. The invention may also be embodied or applied by other different embodiments. Please refer to Fig. 1, which is a schematic diagram of the basic structure of the map information updating apparatus of the present invention. As shown in the figure, the map information updating apparatus 1 of the present invention is applied to an electronic device having a positioning function, such as a mobile phone, a personal digital assistant (PDA) or a navigation device, etc., and the map information new device 1 includes The map database 10, the positioning signal receiving module u, the Gps signal receiving module 12, the coordinate calculating module 13, the map updating module and the mode switching module 15. The map database 10 is used to store map data, which is stored in a storage medium. The map data stored in the map database 10 is a type of information showing geographic information such as roads, buildings, terrain, and landforms in a specific area. The map information can be used to understand the geographic information of a specific area. In the invention, the map data is used to assist the coordinate data to indicate the location of the electronic design. ° The positioning signal receiving module u is used to receive the positioning signal. The so-called positioning signal refers to a message that can determine the location of the device receiving the signal. For example, a signal transmitted by a Global Positioning System (GPS) satellite is a kind of positioning signal, and the nickname issued by a wireless communication base station in its range of range can also be used as a positioning signal. For example, an access point of a wireless local area network, the signal sent by the working range is also a positioning signal. The 2 Π 0930 8 201022636 bit signal received by the positioning signal receiving module u of this embodiment does not include the GPS signal. For example, the positioning signal can be a mobile communication system signal and/or a wireless network system signal. The GPS signal receiving module 12 is configured to receive GPS signals. Since the GPS satellite continuously transmits the GPS signal, the GPS signal receiving module 12 can be turned on at any time as long as the GPS signal receiving module 12 is turned on. The coordinate calculation module 13 is configured to calculate the coordinate of the positioning signal and/or the GPS signal corresponding to the map data. Since the electronic device having the positioning function must be positioned by coordinates, the received positioning signal and GPS signal must be converted into coordinates by the coordinate meter different module 13. The usual practice is to construct a coordinate database of positioning signals. When the coordinate calculation module 13 obtains a specific positioning signal, the coordinate database is pre-established to find the coordinates corresponding to the positioning signal. The map update module 14 is used to update the coordinates of the positioning signal or the coordinates of the GPS signal in the map data. Since the coordinate system is constantly changing with the movement of the buns device having the positioning force, the map update is required. The core group 14 updates the latest coordinates to the existing map data. The mode switching module 15 sends a trigger number to the map update module 14 for switching the update mode of the map data according to the Gps signal receiving state, the positioning signal = the receiving state, the power maintaining state, and/or the map data state. The mode switching module 丨5 is in the map information updating device 1 of the present invention, and the important function of the phase field, the mode switching module 15 must switch the map update mode according to different states, so that the map data updating device of the present invention is sufficient. Balanced power saving while maintaining map updates. Furthermore, the mode switching module 15 determines according to the external input signal that 9 110930 201022636 whether to send GPS signal coordinate update information or positioning signal coordinate update information. The external input signal is received by the electronic device to initiate or close the GPS signal receiving request, for example, the user generates the activation or closing request by pressing a button provided on the electronic device, or is offset by the electronic device. The GPS signal strength is measured to generate the start or close request. The trigger signal may include GPS signal coordinate update information, and the map update module 14 is configured to update the GPS signal coordinate to the map data and the location signal coordinate update information, so that the map update module group 14 is used. Update the positioning signal coordinates to the map material. In the specific implementation of the present invention, the map data of a specific area is first stored in the map database 10, and then received by the GPS signal receiving module 12

Under normal circumstances, the coordinate calculation module 13 converts the received gPS nickname into coordinates, and then the map update module 丨4 updates the coordinates of the Gps signal to the map data. In this way, the user can instantly know the current location through the map information update device. The above process is also the operation of the conventional Gps φ positioning device. However, in a special case, the GPS signal strength is easily blocked and dry, so the effect of the clamp is naturally affected, for example, the weather is not good. ^When the cloud is dense, the GPS signal cannot penetrate the thick cloud' GPS signal The receiving module 12 may not receive the Gps signal. For example, if the user is located under the two bridges and there are buildings on both sides, it is not easy to receive the milk signal. The GPS signal receiving module 12 can not receive the GPS signal or the GPS signal is too low. Updating to map data is therefore a great problem for users. When the mode switch 110930 10 201022636 of the present invention detects that the GPS signal reception status is abnormal, it will immediately send a trigger signal to the map update module 14 for switching the update mode of the map data. Since the positioning signal receiving module 11 can continuously receive the specific type of positioning signal, the local map updating module 14 can update the coordinates of the positioning signal to the map data immediately when receiving the trigger signal, so the map information updating device of the present invention does not Stop updating the coordinates because the GPS signal is not received. However, the resolution of the coordinates is determined according to the type of the positioning signal. In a specific embodiment, the speed of the start of the GPS signal receiving module 12 is slow. Therefore, the user has to wait a few minutes to complete the update of the first coordinate when the user just turns on the general GPS positioning device. The map information updating device of the present invention can first enter the coordinate updating mode of the positioning signal when the power is turned on (usually the resolution is low). When the GPS signal receiving module 12 can start working, it can switch back to the coordinate updating mode of the GPS signal, for example, When the strength of the GPS signal received by the Gps signal receiving group 12 is greater than a specific value, the mode switching module 233 sends the GPS signal coordinate update information to the map update module 232' according to the received GPS signal. The coordinates update the map material. Therefore, the electronic device can continue to perform the positioning function without interruption. In the preferred embodiment, since the Gps signal receiving module 12 is more power consuming, the mode switching module 15 transmits when the power of the map information updating device of the present invention is lower than a certain value or switches to the power saving mode. The positioning signal coordinate update information is sent to the map update module 14 to update the coordinates of the map update module heart positioning signal. The benefit is that the standby and usage time of the electronic device can be extended, and the electronic device can continuously provide the function of positioning 110930 11 201022636. In another preferred embodiment, the user can set the map sentence update device of the present invention to preferentially execute the update mode of the location signal coordinates. Example ^ In the suburbs or mountains, the density of buildings or roads is low. To reduce the power consumption of the map information update device, the mode can be set to use the positioning signal coordinates to update the map data. However, if a special situation occurs in which the location signal transmitting device fails due to an earthquake, so that the device does not receive the positioning signal or the received signal strength is too low, the mode switching module 15 β can transmit the GPS signal coordinate update information to the map update. The module 14 switches to the GPS coordinate update mode (because the GPS signal transmitter is affected by the earthquake). In another preferred embodiment, the mode switching module 15 can switch the coordinate update mode according to the state of the map data. If the user has to drive through the A, B, and (: ground, the ground is the suburb, the B For the mountainous area, the c is the city. Based on the positioning efficiency considerations, the A is set to use the GPS signal to set the position of the box B. Because the area is sparsely populated, the GSM base station signal is set to locate, and the C area is densely populated and full. The wireless local area network is set to use the WLAN signal to locate. When the user is in the A place, the map data shows the coordinate A, so the GPS signal positioning mode is activated. When the user is in the A place When the map data indicates that the coordinates are B, the mode switching module 15 sends the GSM signal update information to the map update module η to switch to the GSM coordinate update mode. Similarly, when entering c, the mode switching module 15 transmits the WLAN. The number update information is sent to the map update module 14 to switch to the WLAN coordinate update mode. 110930 12 201022636 Please refer to FIG. 2 for displaying the basic information of the map information update device of the present embodiment applied to a mobile phone 2. Architecture The mobile phone 2 includes a display screen 20, a positioning signal receiving module 21 for receiving the Qing signal, a GPS signal receiving module 22, a map database 23, a coordinate calculating module 231, a map updating module 232, and a mode. The switching module 233. In the specific implementation, the positioning signal receiving module 21 must continuously receive the signal from the GSM base station 25 in order to perform the function of transmitting and receiving the mobile phone. The GSM signal receiving module 22 can receive the transmission by the (jps satellite 24). The nickname is converted into a map coordinate by the coordinate calculation module 231, and the map update module 232 extracts the corresponding map data from the map database 23 according to the map coordinate, and displays the map data on the screen. The mobile phone 2 of the present embodiment implements a method for locating a progressive map information update through the mode switching module 233. Usually, when the user opens the map software to view the map, the map software passes through the positioning signal receiving module 21 After receiving the GPS signal and calculating by the coordinate calculation module 231, the coordinate can be obtained and the coordinate information can be updated by using the map update module 232. However, the process of updating the coordinates depends on the strength of the GPS signal, the speed at which the GPS signal is converted to coordinates, and the speed of the mobile phone. It usually takes a few minutes to 'lose the timeliness of viewing the map. At this time, when the GPS signal is not yet available. When converted to coordinate information, the mode switching module 233 notifies the map update core group 232 to update the map information by using the coordinates of the GSM signal. Since the GPS signal locates the coordinate range of about tens of meters, and the signal range transmitted by the base station is about Hundreds of meters, so the resolution of the coordinates of the GSM signal on the map is lower than the resolution of the GPS signal on the map. Therefore, 13 110930 201022636 :! The progressive information means that the GPS signal has not been converted into coordinate information. ΪΓ: The map information update device uses a less-resolved coffee " No, when the gps signal receiving function can operate normally, it switches to a higher resolution GPS signal coordinate mode. In a preferred embodiment, based on the power considerations, when the mobile phone drops to a certain level, in order to keep the mobile phone running continuously, the mode switching module 233 can notify the map update module to switch to the GSM nickname coordinate. Update mode. Because of the '', the user can still see the location's ss resolution is poor), you can also increase the monthly navigation of the mobile phone 2 by the function of the side GPS signal reception and processing. Please refer to FIG. 3 for displaying the signal receiving state of the mobile phone 2 disposed in the mobile vehicle 32 shown in FIG. 2. The GPS satellite 30 can provide GPS signals for positioning using 300a, 300b in the figure. 30〇c, 300d, 3〇〇e, 3〇〇f, _ are coordinates for the conversion of the milk ginseng signal. Since the mobile phone is equipped with the mobile phone 2', the built-in copy can be used when the vehicle 32 advances. The map information updating device 23 of the invention performs positioning, and displays the current position on the display screen 2 of the mobile phone 2 in accordance with the coordinates obtained by the positioning. The basic functions of the GSM base stations 31a, 31b are provided. The mobile phone 2 transmits and receives the communication signal 'When the mobile phone 2 is within the coverage of the GSM base station, it can be used normally. In this embodiment, the GSM base station is used for positioning, and the map information updating device 2 of the present invention is used.

As shown in the figure, the coverage of the GSM base station The range is large. For example, any point within the coverage of the GSM base station 31a represents the coordinates 310a, and any point within the coverage of the GSM base station 311) = the coordinates 310b. The same area can be found. The number of Gps seatposts shown in the figure is greater than the number of GSM coordinates, because the coverage of the GSM base station is about a few meters, and the resolution of the GPS coordinates can reach tens of meters. Therefore, if the gSM coordinates are used to update the map data, The level of detail is less detailed than the Gps coordinates. The map database 230 can store the map data of the reachable range of the vehicle 32. The location signal receiving module 21 and the GPS signal receiving module 22 for receiving the GSM signal receive the positioning signal. The coordinate calculation module 231 converts the signal into coordinates, and finally updates with the map update module and displays the location of the vehicle crime on the display screen 20 of the mobile phone. So the driver can immediately grasp the geographic location.
