Design And Implementation Of Online Examination System For Special Operators In Coal Mining Industry

Coal mining belongs to a high-risk industry.Safety training examination of special operations personnel has been using traditional methods, namely the traditional written test or LAN exam.The disaddavantages of traditional test is obviously, such as, resources can not be shared effectively, item bank is not updated quickly,fairness of results can not be guaranteed and social coats of exam is too high, and etc.To ensure safety in production, and to strengthen the significance of safety training in prevention accidents of production, it’s important to speed up the construction of coal mine network examination system of special operation personnel, and also important to enhance safety training work standardization.According to the production safety law of the people’s Republic of China, and managements of safety training in production of The State Administration of production safety supervision and management,and other laws and regulations, aimed at characteristics of safety production training for coal special operations personnel,and based on system requirements analysis, this paper divides network examination system into several modules of functions. It focuses on question bank management module and students online examination module. According to database designation the writer builds database and creates database interfaces by using HIBERNATE framework. According to the design of function interface, realize the users expressed layer by using STRUTS framework. According to the functional logic among modules, utilizing object-oriented ideas of closed and inheriting, build sequence diagram model of business, integrate Spring framework, realize the development of business logic layer. This system is tested by user case method, including function testing, interface testing and also performance testing. Finally, a multi-functional network examination system is accomplished, which includes functions of knowledge management, item bank management, setting rules of management, automatically generating test papers, automatically accounting scores, online examination, etc.
