Research On Intelligent Review Of Airport Radio Navigation Source Material

The production of aviation information products is related to the safe operation of civil aviation,which requires the supply of information products must be accurate and timely.At present,we still adopt artificial method to audit the original data,not only the personnel load,because the intelligence personnel qualification is inconsistent,human error is also more.In the context of intelligent civil aviation,aviation information service in our country should be transformed to digital direction.Based on aviation information secondary institutions,this thesis proposes an intelligent audit scheme for the original data reported by airports,and takes the addition of radio navigation facilities as an example to study key technologies.Firstly,based on the theory of user behavior,the recognition degree of intelligence personnel to the intelligent audit system is analyzed and the possible problems are predicted to improve the audit efficiency.Then,the kano model is used to analyze the requirements of auditors to understand their requirements in the civil aviation industry and system performance,and the requirements are analyzed and converted into product characteristics.According to the life cycle theory,the review time of different original materials is divided,and the review of the body of the checklist is divided into two ways according to the data type.For the items in the regulation manual with clear audit basis,a full intelligent audit scheme based on regular expression is proposed.For the items filled in without clear audit rules,man-machine interactive semi-intelligent audit is realized by making historical error library.For the uploaded attachments,YOLOv5 s identification seals are used to ensure the validity of the documents,OCR technology is adopted to extract key information of the documents and associate and match with the corresponding data of the text to meet the consistency of the data.Finally,an intelligent audit system is built based on JAVA platform to display the research results of this paper.The system includes user registration,login,audit and result feedback,etc.The horizontal and vertical theory is adopted to analyze and evaluate the system,so as to analyze the characteristics of intelligent audit and the advantages compared with traditional manual audit.
