Abstract:
     A unique code collective creation method belongs to the coding technology field. The invention adopts the improved exhaustion method to quick create the entire gather of the special coding-length coding that accord with the specified mathematic standard, firstly the mathematic standard divide into two types: the processing mathematic standard and the final mathematic standard; secondly processing the coding and creating the code collection; distinguishing the code bunch of the repeat, the taking-inverse repeat, the mirror image repeat and the taking-inverse mirror image repeat by the two-dimensional forming method in any two groups of coding. The character of the invention is: it is foreign to the frondose mathematic standard, can create the code collection with the random coding type and the length of the code, which ground for the large-scale application of the special code. Combine the code of the invention and the micro-mechanical code lock that is made by the MEMS (micro-electromechanical system) technology, which can be used in the field with high safety requests.
