Description

Mobile communication device with landmark communication function and its landmark data query method

technical field

The present invention relates to a mobile communication device and a data query method thereof, in particular to a mobile communication device with a landmark transmission function and a landmark query method thereof, which not only can directly transmit a landmark coordinate data to other users in the form of a message, but also It can reduce the secondary transmission to the system operator, thereby reducing the cost and quickly providing the user with a landmark coordinate information.

Background technique

With the consumer demand derived from the advancement of science and technology, electronic products tend to develop in multiple ways, so that various electronic products have changed from a single function in the past to the current integration of multiple functions in one machine.

Therefore, the current mobile communication devices also have multiple functions, such as the integration of functions such as cameras, walkmans and even position determination.

Among them, in order to achieve the function of position measurement, two methods are used to achieve the above-mentioned purpose in known mobile communication devices with positioning function:

1. The geographical coordinate data of the mobile communication device is measured by the position measurement module of the mobile communication device itself.

2. By means of triangulation and calculation of the communication distance between the mobile communication device and multiple communication base stations, the geographical coordinate data of the mobile communication device is determined.

Although the above method can measure the geographical coordinate data of the mobile communication device for the user to browse the latitude and longitude of its location, but because the digital data of longitude and latitude is just a meaningless digital data for ordinary users, it cannot be directly Convert it into geographical location information that is helpful for understanding. Even professionals who have a better understanding of geographical location need to refer to the map to roughly determine their current location. This method cannot provide users with a simple, fast and easy-to-understand function. .

Later, someone improved the above two methods, so that the data transfer process is shown in Figure 1.

It mainly uses the mobile communication device 11 to measure a geographic coordinate data 113, and sends the geographic coordinate data 113 back to the system operator 15 through the mobile communication device 11, and the system operator 15 then transmits the geographic coordinate data 113 to its Cooperated with 19 information providers. The information provider 19 uses the map information system it has built to calculate and process the geographical coordinate data, and find out the prominent landmarks or other relevant information adjacent to the geographical coordinate data 113 from the database of its map information system. , and then convert the landmark data and related information into messages and send them to the system operator 15, and then the system operator 15 sends the messages to the mobile communication device 11 of the user, so as to provide the landmark information and related data 191 required by the user.

Although the above-mentioned known technology can transmit a message containing the landmark coordinate information 191 to the user's mobile communication device 11, so that the user can correctly determine the location, but, when transmitting the message, it needs to go through the user's mobile communication device 11 to the system operator. 15, and then send it to the information provider 19 to obtain the landmark coordinate data 191 and send the message back to the user's mobile communication device 11 through the system operator 15's host computer. In addition to the cost of multiple message transmissions and query costs, it also takes more time in the transmission process and loses the real-time availability of data.

Detailed ways

First of all, please refer to FIG. 2 and FIG. 3 which show a block diagram of modules and a schematic diagram of division of landmark blocks in a preferred embodiment of the present invention.

As shown in the figure, the main structure of the mobile communication device 21 with landmark transmission function of the present invention includes: a communication module 23 , a data storage module 29 , a location measurement module 25 and a calculation module 27 . Wherein, the data storage module 29 stores several landmark coordinate data 275, and the user can use the location measurement module 25 to measure the geographic coordinates of the location of the mobile communication device 21, such as longitude and latitude; then the geographic coordinates are sent to the computing module 27 for calculation In order to compare the landmark coordinate data 275 stored in the data storage module 29 to find the landmark coordinate data corresponding to the geographic coordinates, and display it on the mobile communication device. The user can also use the communication module 23 to send the corresponding landmark coordinate data to a designated target, such as another user's mobile phone, a monitoring and tracking system, etc., via the wireless network 31 in the form of a message.

The wireless network 31 used in the present invention can be selected as a wireless network composed of one of CDMA, GPRS, GSM, PHS and other wireless communication protocols.

The landmark coordinate data 275 in the data storage module 29 is pre-established and stored in the data storage module 29 . In this embodiment, a map data is mainly divided into several landmark blocks 293 with the longitude lon and latitude lat each 60 seconds as the basic unit area, and each landmark block 293 is given a specific index number. Each landmark block 293 includes several landmark coordinate data 291 respectively, and each landmark coordinate data 291 can contain the geographic coordinates of the landmark and the data related to the annotation, and can be selected in the form of text data, graphic data or The types of text data and graphic data used simultaneously are recorded in the data storage module 29 .

The position measuring module 25 of the present invention can use the Global Positioning System (Global Positioning System; GPS), measure the geographic coordinate data 253 of the position of the mobile communication device 21 through the mode of satellite positioning, and transmit this geographic coordinate data 253 to the computing module 27. The calculation module 27 performs calculations, and determines the corresponding landmark block 293 of the geographical coordinate data 253 according to the index data in the data storage module 29, and then performs a landmark search in the range of the corresponding landmark block 293, which can quickly enter the local area. The precise search phase of the system greatly reduces the time required for the search.

When the calculation module 27 performs calculation and search, it mainly compares the measured geographic coordinate data with the landmark data 291 pre-stored in the corresponding landmark block 293 in the data storage module 29 . When the comparison result has at least one landmark coordinate data 291 that matches or is close to the geographic coordinate data 253, the landmark coordinate data 291 is displayed on the display of the mobile communication device 21 for users to consult and view landmarks near their location and its related data. In addition, the user can also select the appropriate landmark coordinate data 291, and use the communication module 23 in the mobile communication device 21 to transmit the landmark coordinate data 275 in the form of text message or graphic data to the specified user's mobile phone via the wireless network 31. The mobile phone or other wireless communication devices can enable other users to easily know the location of the sender by using the landmark coordinate data 275 .

In order to prevent the position of the geographical coordinate data 253 measured by the position measurement module 25 from being located at the edge area of the corresponding landmark block 293 determined by the calculation module 27, resulting in closer landmark coordinates 297 in the adjacent landmark block 295 But the error that cannot be included in the calculation range; or the situation that the landmark coordinate data 291 that meets the conditions cannot be found in the corresponding landmark block 293, the present invention can use the increment Δ of longitude and latitude to expand the scope of search and comparison To the range including other adjacent landmark blocks 297 , and search again for matching or close landmark coordinate data in this extended range, so as to obtain landmark coordinate data 291 close to the geographic coordinate data 253 . Of course, the landmark coordinate data 291 obtained from the search can be directly displayed on the display of the mobile device 21 , and the user can also select appropriate landmark coordinate data 291 and use the communication module 23 to send it through the wireless network 31 .

Wherein, the increment Δ of the longitude and latitude is to gradually increase the side length of the original landmark block from the original longitude lon and latitude lat to 60 seconds each, so as to expand the scope of calculation search. In the present invention, it is recommended that the extended range should not exceed three times the side length of the original landmark block 293 at most, that is, the longitude and latitude of the extended range should not exceed 180 seconds. When the calculation module 27 repeatedly expands the search range with an increment Δ, and the size of the expansion reaches three times of the original landmark block 293, and the appropriate landmark coordinates cannot be found, the calculation module 27 stops searching and directly displays the mobile communication device. 21 The geographical coordinate data 253 of the location is provided to the user for viewing and reference.

By using the user's mobile communication device 21 to directly query the landmark coordinates of the location and the surrounding prominent landmarks, not only can the geographic coordinate data 253 and landmark coordinate data 291 be directly and quickly obtained, but also the landmark coordinate data 291 can be directly transmitted to other users. Mobile communication devices can quickly achieve the effect and purpose of positioning and communication without the need for repeated information transmission and calculation queries by system operators and information providers.

Please refer to FIG. 4 for a flow chart of query operation in a preferred embodiment of the present invention. As shown in the figure, the landmark query method of the present invention mainly includes the following steps: first, the geographic coordinates 401 of the location are measured by the position measurement module; the operation module is used to determine the corresponding landmark block 403 of the geographic coordinates; Search 405 for landmark coordinates within the block range. In step 405, if matching or close landmark coordinates are found in the block, step 407 is executed to display the landmark coordinate data obtained from the search. The user can select an appropriate landmark data 409 according to the displayed data, and then transmit the landmark data to another designated mobile communication device or receiver 430 via the wireless network.

If in step 405 , no matching or close landmark coordinates are found in the corresponding landmark block, the search range 425 is expanded around the corresponding landmark block by an increment around the center. In order to prevent the search range from being infinitely expanded and lose the meaning of positioning, this embodiment limits the increment of range expansion to no more than 60 seconds 427 . If the increment is not greater than 60 seconds, execute step 405 to search for matching or close landmark coordinates to form a loop; if the increment is greater than 60 seconds, then directly display the geographical coordinate data 429 measured by the location measurement module. The user can also transmit the geographic coordinate data to a designated receiver or mobile communication device 430 via the wireless network.

The mobile communication device and its landmark query method of the present invention can also be applied to the positioning and tracking of children or valuables,

Finally, please refer to FIG. 5 which is a module block diagram of another embodiment of the present invention. In this embodiment, the location measurement module 55 , the computing module 7 and the data storage module 59 can be manufactured and integrated into an independent location measurement unit 51 , for example implemented in the form of an identification chip. The user only needs to install the mobile communication device 53 on a mobile communication device 53 with compatible expansion functions, and the mobile communication device 53 can be endowed with the function of landmark transmission.

Of course, in the above-mentioned embodiments, the data storage module can be a memory card, so that the landmark coordinate data stored in the data storage module can be updated at any time, and can be applied to different geographic regions. In addition, the data storage module can not only store text information, but also record image data, such as the shape of the landmark, landscape and other graphics, which can help users quickly and accurately identify the coordinate data of the landmark.

To sum up, the present invention is a mobile communication device and its data query method, especially a mobile communication device with a landmark transmission function and its landmark query method, which not only can directly transmit a landmark coordinate data in the form of a message To other users, and can reduce the secondary transmission to the system operator, thereby reducing costs, and quickly provide users with a landmark coordinate information.
