Description

Examination data classified receiving and transmitting method and system Technical Field The invention relates to the technical field of computer aided education, in particular to a method and a system for classifying, receiving and transmitting examination data. Background In the prior art, in order to ensure data security in high-interest examination, an off-line physical escort mode is generally adopted, so that examination data cannot be transmitted in real time, and a command center is difficult to respond dynamically. While the conventional online examination mode supports real-time transmission, the conventional online examination mode is based on a single channel of the public Internet, so that the national security requirement of examination and answering data cannot be met, and the safety and the instantaneity are affected due to mutual interference caused by mixed transmission of the examination and answering data. With the development of education informatization, paperless machine-test systems are becoming popular. The current examination data transmission mode is mainly divided into two modes, namely ① off-line mode, namely, the mode is used for high-interest examination, data is escort under the line through physical media (such as a USB flash disk and an optical disk), and the safety is high but the examination data cannot be transmitted in real time. ② The on-line mode is used for general examination, data are uniformly transmitted through the Internet, and the on-line mode can be used for monitoring in real time, but the safety is insufficient, and all the data share the same link, so that the transmission efficiency is influenced. As shown in fig. 1, the conventional on-line test system generally adopts a data transmission path of' test center server → test point server → examination monitor → examination machine And examination data (examination papers and answer papers) and examination service data (examination staff state, equipment abnormality, statistical information and the like) are transmitted through the same internet link, and the security classification and link separation of the data are not carried out. In the prior art, the data transmission process is as follows: 1. And the examination data is issued, namely the examination center server issues the examination paper package to each examination point server through the public internet. 2. And the examination room distribution is that the examination point server distributes the examination papers to the invigilator through the campus local area network, and the invigilator distributes the examination papers to each examination machine through the machine room local area network. 3. And the answer sheet returning step of reversely returning the answer sheet data through the original path (terminal, prison machine, examination point server and examination center server) after the answer sheet of the examinee is finished. 4. And (3) test data transmission, namely, test data such as test staff states, equipment abnormality, login information and the like generated in the test process and test data share the same transmission channel, and the test data are uploaded to a test center server in real time or near real time. Although the prior art can realize a certain degree of real-time monitoring, the national cryptographic requirements of high-interest examination on data security cannot be met, and examination data and examination answer data are transmitted in a mixed mode, so that the real-time performance and the bandwidth utilization rate are affected. In summary, the prior art has an obvious contradiction that the national security level safe transmission of the examination answering data and the real-time and high-efficiency transmission of the examination service data can not be realized in the same high-interest examination. Therefore, how to realize the rapid transmission and visual monitoring of the examination data through the independent real-time link while guaranteeing the safety of the examination data through the special safety link in the high-interest examination, so that the dual requirements of the highest safety level and the real-time command and dispatch are met in a single examination at the same time, which becomes a technical problem to be solved by the technicians in the field. Disclosure of Invention In view of the above-mentioned drawbacks of the prior art, the present invention provides a method and a system for classifying and receiving test data, which can ensure the safety of the test data through a special safety link and realize the rapid transmission and visual monitoring of the test data through an independent real-time link in a high-interest test, so as to simultaneously satisfy the dual requirements of the highest safety level and real-time command and dispatch in a single test. In order to achieve the above purpose, the invention discloses a classified receiving and transmitting method of
