Embodiment Construction

[0022] In order to have a deeper understanding of the present invention, a specific embodiment is listed below, and the present invention is further described in detail in conjunction with the accompanying drawings.

[0023] Generally, sorting can be performed by one-to-one correspondence between hexadecimal numbers and characters within a certain range, so that sorting can be performed by comparing the size of hexadecimal numbers. But ASCII is only suitable for the comparison of Latin characters, and GBCode can only be converted with Chinese characters, so it is only suitable for comparison of Chinese characters. Sorting with the Unicode method actually takes care of the mixed characters and realizes the unified sorting of the maximum data set.

[0024] figure 2 It is a plurality of different fields in one embodiment of the present invention, combined below figure 2 The examples explain and illustrate the present invention in detail according to the methods provided by th...

Abstract

The invention provides an ordering method and device of mixed fields. The ordering method and device of the mixed fields is characterized by comprising the following steps that all characters in the mixed fields are converted into Unicode values; the Unicode values of the converted fields are compared and ordered, and if the Unicode values of two fields are completely the same, the Unicode values of all Chinese characters in initial Chinese character fields are compared one by one and are ordered. The ordering method and device of the mixed fields can effectively avoid the situation that the code values after conversion of the Chinese characters and letters are the same and the ordering problem caused by errors of code values of homophone Chinese characters and multiple Chinese characters due to the fact that complete spelling letters are the same, reduces ordering errors and improves retrieval efficiency.

Description

technical field [0001] The invention relates to a sorting method of characters, especially for a sorting method of mixed fields in an intelligent terminal or a vehicle-mounted multimedia system. Background technique [0002] The car multimedia system represented by car navigation and car radio has quickly entered the era of intelligence. Especially in recent years, the interaction with smart phones has become an essential function of smart vehicle systems. With the increase in the amount of interaction between mobile phone book, Bluetooth audio, USB audio files and other content, pure Chinese display can no longer meet the needs of smart devices. It is a problem that must be solved that all information, like mobile phones, can be sorted according to certain rules and can be retrieved quickly. However, the sorting methods of various information in various mobile phones are different, and the way in-vehicle devices are made is different from mobile devices. In the existing ...
