Abstract: Based on object-oriented high-level programming language C# running on the.NET Framework, using the Timer timer, ADO.NET2.0 SqlBulkCopy technology, intelligent entrance and exit attendance software system for mine wells is developed. System combines KJ405T personnel positioning system with mine enterprises attendance system and solves the practical problems of statistics and analysis of intelligent entrance and exit attendance, automatic generation and management of all kinds of statistical reports of attendance. The paper introduces the basic software solutions and applications of the intelligent attendance software system. The test results at the scene show that the intelligent attendance software system based on C# accords with actual hardware conditions of mining enterprises with lower environment requirements.
