    [0109] 1. b.sub.11, Postfix can only be spelled with b.sub.i, Suffix, (i=12, 25, 26).

    [0110] 2. b.sub.28, Postfix can only be spelled with b.sub.i, Suffix, (i=3, 4, 15, 16).

    [0111] Tibetan spelling grammar 17: when being spelled with the Tibetan subscripts corresponding to b.sub.j, Subfix, (j=24, 25), the Tibetan radicals corresponding to b.sub.i, Root, (i=3, 11, 14) can be simultaneously spelled with the Tibetan subscripts corresponding to b.sub.20, Subfix. The specific rules are as follows:

    [0112] 1. when being spelled with b.sub.25, Subfix, b.sub.i, Root, (i=3, 11) can be simultaneously spelled with b.sub.20, Subfix.

    [0113] 2. When being spelled with b.sub.24, Subfix, b.sub.14, Root can be simultaneously spelled with b.sub.20, Subfix.

    [0114] Tibetan spelling grammar 18: the Tibetan consonants corresponding to b.sub.29, Root can be spelled with the Tibetan consonants corresponding to b.sub.14, Root, and b.sub.14, Root is correspondingly located below b.sub.29, Root.

    [0115] Tibetan spelling grammar 19: when being spelled with the Tibetan consonants corresponding to b.sub.14, Root, the Tibetan consonants corresponding to b.sub.29, Root can be simultaneously spelled with the Tibetan postscripts corresponding to b.sub.i, Suffix, (i=3, 4, 11, 12, 15, 16, 23, 25, 26, 28).

    [0116] Tibetan spelling grammar 20: the Tibetan characters having no postscript can be spelled with the Tibetan consonants corresponding to b.sub.23, Root, and at this time, the Tibetan consonants corresponding to b.sub.23, Root must be spelled with the vowels (i, e, u, o) corresponding to v Vowel, Vowel={i, u, e, o}.

    [0117] Tibetan spelling grammar 21: except the special spelling in the grammars 17, 18, 19 and 20, the Tibetan characters are spelled according to the sequence of the prescripts, the superscripts, the radicals, the subscripts, the vowels, the postscripts and the post-postscripts.

    [0118] Specifically, to satisfy the ambiguous layout rule, the layout of the input module of the Tibetan input device can be shown in FIG. 3, on the Tibetan input keys, the Tibetan consonant and the Tibetan subscript custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan vowel custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan vowel custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan vowel custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, and the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit. The Tibetan subscript custom-character is deformed into custom-character when being written; the Tibetan subscript custom-character is deformed into custom-character when being written; and the Tibetan subscript custom-character is deformed into custom-character when being written.

    [0119] At this time, as shown in FIG. 3, among the other Tibetan characters excluding the Tibetan consonant custom-character, the Tibetan subscript custom-character, the Tibetan consonant custom-character, the Tibetan vowel custom-character, the Tibetan consonant custom-character, the Tibetan vowel custom-character, the Tibetan consonant custom-character, the Tibetan vowel custom-character, the Tibetan consonant custom-character, the Tibetan subscript custom-character, the Tibetan consonant custom-character, the Tibetan subscript custom-character, the Tibetan consonant custom-character, the Tibetan subscript custom-character, the Tibetan consonant custom-character, and the Tibetan subscript custom-character, each Tibetan character corresponds to one storage unit.

    [0120] To input an instruction, in the Tibetan input system provided by the embodiment of the present disclosure, the input module is further used by the user for inputting the instruction;

    [0121] the storage unit further stores an instruction character, and the instruction character includes one or more of a control character Ctrl, an alternate shift character Alt, a shift conversion character Shift, a carriage return character Enter, a backspace character Backspace, a tab character Tab and a capslock character Capslock; and

    [0122] the processing device is further used for obtaining the instruction character corresponding to the input key according to the keyboard definition module when the user inputs the instruction through the input key, and executing the instruction corresponding to the instruction character.

    [0123] To input Chinese, English and other characters, the Tibetan input module can switch Tibetan input, Chinese input and English input through the keys, as well as switching through the instruction, and this is not limited herein.

    [0124] The layout of the input keys of the input module in the Tibetan input system provided by the embodiment of the present disclosure can be shown in FIG. 3, other modes can also be available, as long as the storage unit satisfies the ambiguous layout rule.

    [0125] In the embodiment, when the user needs to input characters beyond the pre-combined Tibetan characters stored in the Tibetan font, the processing device may not determine the target pre-combined Tibetan character, at this time, the processing device can prompt the user about all possible character combinations, and then input the characters beyond the pre-combined Tibetan characters stored in the Tibetan font according to the indication of the user.

    [0126] The present disclosure has the following beneficial effects: when the user inputs the

    [0127] Tibetan characters through the input keys, the initial Tibetan characters corresponding to the input keys are obtained according to the keyboard definition module; and the target pre-combined Tibetan character is determined according to the initial Tibetan characters and the Tibetan font, and then is output. According to the technical solutions provided by the embodiment of the present disclosure, when each storage unit stores a plurality of Tibetan characters, the preset ambiguous layout rule is satisfied, therefore the input module has no redundant code and repeated code, and only 6 very common Tibetan characters correspond to the shift key. Thus, the following problems in the prior art are solved: when one Tibetan character corresponds to one key position, although the Tibetan input method has no repeated code, it contains a large number of redundant codes, namely dead keys; when one Tibetan character corresponds to a plurality of key positions, although it is easy to remember, there are repeated codes; and when a plurality of common Tibetan characters correspond to the shift key position of the keyboard, although there is no repeated code, a large number of shift key positions are present, so the Tibetan input efficiency is relatively low.

    Second Embodiment

    [0128] As shown in FIG. 4, the embodiment provides a Tibetan input method including the following steps:

    [0129] Step 401, whether a plurality of preset input keys are pressed down is detected.

    [0130] In the embodiment, the distribution mode of the plurality of input keys can be shown in FIG. 3, other modes can also be available, and will not be repeated redundantly herein.

    [0131] Step 402, when the input keys are pressed down, initial Tibetan characters corresponding to the input keys are obtained according to a preset keyboard definition module.

    [0132] In the embodiment, the structure and the function of the keyboard definition module are similar to those as shown in FIG. 1. The keyboard definition module includes a plurality of storage units, each storage unit corresponds to one input key, and stores one or more Tibetan characters; and when each storage unit stores a plurality of Tibetan characters, a preset ambiguous layout rule is satisfied. The ambiguous layout rule is similar to that provided in the first embodiment of the present disclosure, and includes: Tibetan superscripts and Tibetan radicals correspond to two storage units; Tibetan subscripts and Tibetan postscripts correspond to two storage units; when the intersection of a set consisting of all prescripts of the Tibetan superscripts and a set consisting of all radicals of the Tibetan subscripts is a null set, the Tibetan superscripts and the Tibetan subscripts can correspond to one storage unit; when Tibetan consonants cannot be spelled with the prescripts and the Tibetan consonants cannot be used as the postscripts, the Tibetan consonants and Tibetan vowels can correspond to one storage unit; and when the intersection of a set consisting of all prescripts of other Tibetan radicals excluding the Tibetan radicals corresponding to the consonants that can be used as the postscripts and a set consisting of all radicals of the Tibetan subscripts is a null set, the other Tibetan radicals and the Tibetan subscripts can correspond to one storage unit.

    [0133] Optionally, in the Tibetan input method provided by the embodiment of the present disclosure, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan vowel custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan vowel custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan vowel custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit, and the Tibetan consonant custom-character and the Tibetan subscript custom-character correspond to one storage unit. No repetition will be given herein one by one.

    [0134] Step 403, a target pre-combined Tibetan character is determined according to the initial Tibetan characters and a preset Tibetan font, and then is output.

    [0135] In the embodiment, the process of determining the target pre-combined Tibetan character in the step S403 includes: judging whether one or a plurality of initial Tibetan characters exist; when one initial Tibetan character exists, using the initial Tibetan character as the target pre-combined Tibetan character and outputting the target pre-combined Tibetan character; when a plurality of initial Tibetan characters exist, obtaining the Tibetan characters that are input in front of or behind the initial Tibetan characters, searching the Tibetan font according to the Tibetan characters that are input in front of or behind the initial Tibetan characters and the initial Tibetan characters, determining the target pre-combined Tibetan character from the plurality of initial Tibetan characters, and outputting the target pre-combined Tibetan character.

    [0136] In the embodiment, when the user needs to input characters beyond the pre-combined Tibetan characters stored in the Tibetan font, the processing device may not determine the target pre-combined Tibetan character, at this time, the processing device can prompt the user about all possible character combinations, and then input the characters beyond the pre-combined Tibetan characters stored in the Tibetan font according to the indication of the user.

    [0137] The present disclosure has the following beneficial effects: when the user inputs the Tibetan characters through the input keys, the initial Tibetan characters corresponding to the input keys are obtained according to the keyboard definition module; and the target pre-combined Tibetan character is determined according to the initial Tibetan characters and the Tibetan font, and then character is output. According to the technical solutions provided by the embodiment of the present disclosure, when each storage unit stores a plurality of Tibetan characters, the preset ambiguous layout rule is satisfied, therefore the input module has no redundant code and repeated code, and only 6 very common Tibetan characters correspond to the shift key. Thus, the following problems in the prior art are solved: when one Tibetan character corresponds to one key position, although the Tibetan input method has no repeated code, it contains a large number of redundant codes, namely dead keys; when one Tibetan character corresponds to a plurality of key positions, although it is easy to remember, there are repeated codes; and when a plurality of common Tibetan characters correspond to the shift key position of the keyboard, although there is no repeated code, a large number of shift key positions are present, so the Tibetan input efficiency is relatively low.
