Local area network-based network examination system and implementation method thereof

Abstract

The invention discloses a local area network (LAN)-based network examination system and an implementation method thereof. The LAN-based network examination system adopts a client/server (C/S) mode framework; an examination room server, an examination affair operating terminal and examinee operating terminals form a local are network; and examination test questions in the examination room server are decrypted by the examination affair operating terminal and then converted into a data format which can be identified by the examinee operating terminals. The examination affair operating terminal classifies and collects data files of problems worked by examinees and archives examination data. The examinee operating terminals display the identified data and provide an examination environment for examinees. The LAN-based network examination system has lower requirements on network and hardware configurations, stronger adaptability and high compatibility, and only each examinee operating terminal is communicated with a twisted pair cable and is connected with each other by using an exchanger to form the local area network, thereby greatly saving the input of network equipment. The examination data are transferred in the local area network and has no physical contact with the internet, thereby guaranteeing data security and stability of the examination system.

Description

technical field [0001] The invention belongs to the technical field of computer network communication, and relates to a system platform for network examination, in particular to a network examination system based on a local area network and its realization method. Background technique [0002] Traditional examination methods generally use paper as a carrier, and generally go through the following stages: First, the examination paper preparation stage: the teacher determines the examination question type according to the examination outline, compiles the examination paper, prints the examination paper and answer sheet, seals the examination paper, transports the examination paper, and seals the examination paper ;The second is the examination stage: unpacking the examination papers, issuing answer sheets, recycling the test papers and answer sheets; the third is the examination paper review stage: the examination papers must be manually reviewed, and the answer sheets are read...

AI Technical Summary

Problems solved by technology

Moreover, once there is a network failure or equipment failure during the test, the test will not be able to proceed normally

Therefore, the construction and maintenance costs of the existing network examination system are relatively expensive

Many economically underdeveloped areas, such as mountain villages, schools at the township level, and units generally cannot afford expensive computer equipment and network hardware investment, which seriously hinders the promotion and application of computer network examination methods
