海洋测绘试卷自动创建系统的构建与实现

Implementation and Realization of Hydrographic Surveying andCharting Testing Paper Automatic Creation System

针对海洋测绘各专业日常技能考试的特点与存在的问题,在构建海洋测绘专业考试题库的基础上,架构了海洋测绘试卷自动创建系统,设计了海洋测绘试卷自动创建系统需要的后台数据库表单,结合实际需要,设置了相应的出题功能,对计算机自动化出题时用到的随机函数以及与数据库ADO访问方式,提出了试题编号的随机向量生成方式与批处理式地向数据库写入方法,加快了出题速度。通过重力测量试卷创建的实例认证,该系统实现了海洋测绘考试的试卷出题的自动化,使得题目分布具有均衡性与全面性,提高了出题效率与出题的客观性,有助于海洋测绘考试的规范性与公正性。

For the characters and existing problems on hydrographic surveying and charting daily ability testing,based on the creation of questions database of all the specialties of hydrographic surveying and charting,this article implements the hydrographic surveying and charting testing paper automatic creation system and designs the forms which are served for the system and are needed for the background running database.Besides,in order to meet the practical demands,the system combines with lots of useful testing paper automatically creating functions and advanced the methods of creating the random testing codes’ vector which are based on the utility of ADO linking method of database.Besides,the system uses both the random functions and the method of writing codes into database in a batch way that greatly fastens the speed of the paper creation.Through the practical testing paper creation of gravity,it proves that the system realizes the automatic procession of creating the hydrographic testing papers.What’s more,it makes the distribution of questions on the result testing paper equal and comprehensive.Thus,the system greatly improves the objectivity and efficiency of the process of testing paper creation and is helpful for the normality and justice of the hydrographic surveying and charting testing.
