A test cloud platform system based on block chain

Abstract

The invention discloses an examination cloud platform system based on block chain in the technical field of examination system, including the CPU, the central processing unit is electrically connectedwith a login subsystem, on-line examination module, fractional comparison subsystem, monitoring subsystem, Query Modules and Databases, the CPU is respectively electrically output and connected withan alarm module, information display module, An information block chain storage module and an error question set subsystem, the device compares the steps of answering incorrect test questions with thesteps of labeling, what is the wrong step to analyze a student, it is convenient for the teacher to know which kind of examination questions the students make mistakes in and which step of the examination questions, Teachers can know which knowledge point students have weak grasp, so that teachers have targeted to explain the test questions to students, and through the wrong questions set block chain storage module to store students' mistakes, facilitating the access of students and teachers, so that students in the review can be targeted to review, to speed up the grasp of knowledge points of students.

Description

technical field [0001] The invention relates to the technical field of examination systems, in particular to a blockchain-based examination cloud platform system. Background technique [0002] Examination is an important means of testing whether students have a solid grasp of knowledge points. With the rapid development of online education and the promotion of paperless office, more and more schools use the online examination system to test students, while the existing The online examination system has a single function and cannot make good use of students' wrong questions and analyze the students' knowledge points. Therefore, a blockchain-based examination cloud platform system is needed. Contents of the invention [0003] The purpose of the present invention is to provide a block chain-based examination cloud platform system to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention pro...
