基于AT89C51和数据库技术的多功能评分系统的设计与实现

采用ATMEL89系列单片机成功开发了多功能综合评分系统．该系统分为管理机和终端机两部分，前者采用Access和VB环境下的数据库技术，后者采用KeilC51开发．系统已广泛地应用于体育比赛、文体表演等场合的现场评分工作，具有处理速度快、操作简单、操作界面友好、数据保存及时准确、比赛结果可现场查询和打印、系统工作稳定等特点．同时，还给出了系统具体的硬件组成和软件流程，以及针对在开发过程中出现的关键问题的解决方案．

The Designment and Realization of Multi-Function Graded System Based on AT89C51 and Database Technology

Based on AT89C51 series MCU , a multi-functional integrated graded system is successfully developed, which includes management and terminal, the former adopting Access and the database technology in the environment of VB, the latter adopting the development of KeilC51. The system has been widely applied in the spot-grading of sports competitions, performances and so on, featuring on fast processing , simple handling , good operating inter- face, timely and accurate data-saving, on-the-spot quering and printing the competition result, and steady working of the system. This article also introduces the structure of the system and the flow chart of software detailed, gives the solutions to the key questions arised in the process of development simultaneously.
