Mobile integrated test server

Abstract

A mobile integrated test server takes a network server as a center, and integrates a USB interface, a GPS module, a 10 / 100 Mbit / s self-adaptive network card, a hardware encryption unit, a video unit, a power supply interface, a 3G module, a Wi-Fi module, a fingerprint verification module, and a lithium battery. The network server includes a CPU, an internal memory, and an SSD solid state disk; the hardware encryption unit is internally provided with an encryption algorithm chip, a clock chip and a digital certificate; the video unit outputs standard VGA videos; the power supply interface supports access of a 12 V direct-current power supply; the Wi-Fi module is used for providing an AP with the wireless routing function; and the fingerprint verification module is used for scanning and recognizing fingerprints. The mobile integrated test server solves the data safety problem, the server reliability problem and the network reliability problem.

Description

technical field [0001] The invention is used for computerized examination and computerized classroom teaching, is the application of cloud computing technology, wireless communication technology, network communication technology and information encryption technology in the field of educational examination, and belongs to the field of computer information processing. Background technique [0002] At present, there are generally two ways of computerized examination: one is the online examination based on the Internet, and the other is the computerized way based on the local area network. The security and confidentiality of online examinations on the Internet are relatively poor, and they are generally only used in fields such as corporate training. The LAN-based computerized examination system has good system security and confidentiality, high efficiency, and good effect in preventing cheating, and solves the shortcomings of traditional paper-and-pencil examinations such as ...

AI Technical Summary

Problems solved by technology

In the process of implementing computerized examinations, people found that there are still some defects in the LAN computerized examination system:

[0004]①Data security issues: The test server system needs to be installed on the test room server in the test computer room, and all test data such as test questions, test papers, candidate answer sheets, etc. Because the computer room is open and has other purposes, anyone can install tracking software, cracking software, remote control software, Trojan horse programs, etc. on the test room server, which seriously threatens the security of test data;

[0005]②Server reliability problem: The examination system is based on the examination server system as the core working method. Once the examination room server has software and hardware failures, the entire examination system will be paralyzed. Affect the normal conduct of the examination

The test server models and service life in the computer room are very different, and there are problems such as equipment aging and insufficient maintenance. Problems such as equipment failure, virus infection, network failure, etc. often occur during the test process, and it is necessary to replace the device or take the test again

[0006]③ Network reliability problem: the test system needs to connect to the test center to obtain the test papers before the test, and transmit the candidates' answer sheets to the test center after the test

During the exam, candidates answer questions on the exam client, and the exam client system needs to transmit the answer sheet data to the exam room server through the LAN in the computer room. Once the network fails, the data cannot be uploaded and downloaded, which will seriously affect the progress of the exam, or even make it impossible to take the exam.
