| Along with the information technology in the field of each social field playing a more and more important role in information technology, as one of the important links in information system, encoding has paid much attention by the domestic and foreign research experts. The rapid development of rural road, jots of information to deal with, made the traditional project management processing, methods to be challenged. To arrange and manage rural road construction reasonably and effectively, it should conduct research of coding system facing the highway information, and gradually formed a relatively independent theoretical system, to provide powerful support for query needs of large-scale rural road data.From the project construction planning overall requirements of principle, convenience, practicability and the overall goals, analyze its main function requirement, and then put forward demand indicators related with project construction planning libraries code design.Introduce information classification and coding theory knowledge, according to encoding principle of the consistency and stability, uniqueness and characteristic, systematic and conciseness, design the code of roads, bridges, tunnels and facilities construction, determine the code form, structure, and position. According to code compiling process, get fixed length (road, bridge, tunnel, facilities) program code respectively which is made up with the code for basic information and extra code for supplementary specification.As ShaanXi rural road Twelfth Five-Year construction planning for example, selected AnKang representative project of rural road asphalt pavement construction, village road asphalt pavement construction, rural road technology grade promotion construction, construction for bridge in danger Etc of ten kinds, Establish coding scheme application. Research proves that, a rational and efficient coding system is very meaningful for improving the management level of rural road construction project, and worth researching. |
