Problems solved by technology

This position expression method is more complicated and not easy to remember. At the same time, its character length is relatively long, which is not convenient for computer storage and transmission. More importantly, different information systems usually use different encoding methods to encode positioning data. Encoding, so that these data cannot be freely transmitted between different information systems

Embodiment Construction

[0037] In an embodiment provided by the present invention, the zoom coding rules adopted may include the following three types, which are:

[0038] First, the 7-bit encoding of the area within China using 8x zoom.

[0039] According to relevant data, the maximum distance from north to south of China's border is about 5500KM, and the maximum distance from east to west is about 5200KM. Therefore, this application uses a square viewfinder frame with a side length of 5500KM, and each zoom factor is 8 times. It can be known by calculation that the accuracy of 7-bit encoding can reach 5500KM / 8^7 which is about 2.62m. Compared with GPS accuracy, this accuracy can fully meet the requirements of location services.

[0040] According to the above calculation, this application needs to use a total of 64 characters of 8*8 for encoding. In order to facilitate computer input and user memory, the application selects 64 commonly used characters to express, that is, 10 Arabic numerals plus ...

Abstract

The invention relates to a rapid geographical position search locating system and a method, and a systematic method for sending and decoding position locating codes. By adopting zooming locating, the method can code any area to be located and establish a complete set of code table. Compared with traditional position expression ways, zooming locating coding can have a shorter code length, and each coded bit can independently indicate one area range, thus being more convenient for memory and sharing of users, and also being more convenient for the input and processing of a computer. The system includes a receiver, a processor, a storage module, a map module, an output device and other parts.

Description

technical field [0001] The invention relates to a system and method for quickly searching and locating a geographical location, more specifically, a zoom positioning method is used for position coding, so as to achieve the purpose of quickly searching and locating. Background technique [0002] Currently, location service providers usually use satellite positioning data, such as the GPS positioning system, when representing location information. These positioning systems use latitude and longitude coordinates for the expression of position, similar to the coordinate data of 120.3456E, 30.1234N. This position expression method is more complicated and not easy to remember. At the same time, its character length is relatively long, which is not convenient for computer storage and transmission. More importantly, different information systems usually use different encoding methods to encode positioning data. Coding prevents these data from being freely transmitted between differ...
