The Design And Realization Of The Answer Sheet Scanning System For Qualification Examinations

Qualification Examinations,a form of examination organized by the state administrative organs or units or organizations authorized by the laws and regulations of the state,is an important part of the Non-degree examinations.There are a number of companies to undertake such examination of the answer sheet scanning.With the increasing number of candidates year by year,the social concern is growing in recent years.Every province organized the examination.After the end of the exam,lots of answer sheet boxes have been sent to the Data Processing Center scanning.The transport of unordered boxes in large quantities.At the same time,The Data Processing Center's data processing projects to increase the implementation of a single project implementation cycle compression.Urgent need to scan the workflow from the answer sheet and scanning procedures to solve the following problems.Firstly,it will be a large number of answer sheets in the absence of finishing in the case of the unit as a unit to scan the formation of electronic images,and the latter can quickly and accurately find the original answer sheet.Secondly,design of an algorithm to generate the secret numbers of examinees.Thirdly,design of an algorithm to solve the problem of disorder processing of the answer sheet.According to the characteristics of the qualification examinations and the problems encountered in the implementation of the qualification examination,the main work of this paper is to design an answer sheet scanning system which is suitable for practicing qualification examinations.The system focuses on two aspects:one is communication between the answer sheet scanning system and the self-developed TS series high speed intelligence scanners with Socket technology and USB communication technology,the other is a software design and implementation of answer sheet scanning.The answer sheet scanning software is focused on the design of the scanning case numbers number and scanning table,the answer sheet out of order processing algorithm and fuzzy number algorithm to stop recording.The system also adds the box numbers of input and identification of the examination rooms.The scanning system uses OCR and 7 segment code recognition technology to ensure the consistency of the answer sheet.The system used image correction technology and noise reduction to reduce the number of answering card scanner downtime.The procedure is applicable to the actual project implementation and also reduces labor,improves work efficiency.My main job is to study comparative analysis of the background and status of the qualifying examination.Put forward the answer sheet scanning system to achieve the goal and need to solve the bottleneck.Describe the requirements and overall design of the answer sheet scanning system for design goals and key issues.This paper focuses on the design and key problems and solutions of scanning software using the means of techniques and algorithms.The system has been successfully applied in many qualification test card scanning projects in 2016.The system provides convenient scanning for data processing service personnel.In order to shorten the implementation of the answer sheet scanning cycle and improve the efficiency of scanning has played a positive effect.
