Abstract:With the increase of the business volume of infrastructure projects, standardize electronic ledger entry data accuracy, the main project higher goal, timeliness and accuracy of determination, not only to accurately establish ledger equipment, components, functional location information, familiar with a wiring diagram and field equipment is needed, and the accuracy of the electronic record of the ledger hierarchy do audit checks. From different dimensions, causes analysis, cause confirmation, countermeasure formulation and implementation methods were carried out, which improved the accuracy of entries, closing rate of ledgers, reducing labor costs, reducing repetitive work and ensuring the timely performance of ledgers. In the professional audit work to be timely audit, timely tracking, timely improvement of information, reduce the waste of resources to improve efficiency. In business as a guide, the "Zunyi Power Supply Bureau infrastructure network transmission line ledger work flow chart", shorten the time of process specification do account, and to enhance the data quality of electronic ledger entry, to achieve the accuracy of electronic ledger structure accuracy, input information, the account can be put into operation on schedule, infrastructure the main information data quality jumped on a level.
