Design And Implementation Of Campus Card Clearing System Based On Petri Net

With the continuous development of the digital campus,as well as the gradual enhancement of school management modernization awareness,the campus card system is playing an important part in the campus informatization.The campus card clearing and settlement system is the key to make the campus card system work properly and reliably,which directly determines the success of the whole campus card system.Based on the researches of campus cards used at home and abroad,the article is to analyze the needs of campus card clearing and settlement system deeply,then to redesign,implement and test the system which results in a better situation.The paper is summarized as follows:Firstly,the theory of Petri net is used to model and analyze the important business processes of the system.PIPE and Exspect software are the professional Petri net simulation tools,which are used to simulate the important business processes of the system,and to analyze the reachability,liveness and boundedness of the business process qualitatively and quantitatively.Then it can ensure the accuracy and rationality of the new-designed system.Secondly,the paper designs the overall architecture of the campus card clearing and settlement system then defines and analyzes the business access layer,the core function layer and business support layer.It also focuses on the security,the interactive interface with third-party systems,the databases,and so on.Thirdly,the paper introduces the realization of the relevant functional modules briefly,makes the detailed functional testing and performance tests for the system-related functional modules and core performance indicators,which leads to the conclusion that the system works stably,availably,with good load performance,and that is easy to be operated with high accuracy.So through the deployment and operation of the campus card clearing and settlement system,it can provide convenient and efficient service for the school teachers and students;it can also be a unified,scientific,modern financial management tools for school financial department,as well as a good reference for important decision-making in schools.
