Achievement And Research On Automatic Identification And Location Service In Library Management

Logistics warehousing is one of the most critical stages of the logistics industry,the automation and intelligent level of which directly affect the quality and efficiency of logistics services.At present,logistics warehousing suffers a low development level,especially in the stage of automation.What's worse,there are still other serious problems.For instance,people need to manually query the book label,determine the library warehousing location,query shelf number before finding the shelf and book due to the inefficiency of the library management.The operation process is cumbersome inefficient and at a low level of automation,especially for those who are not familiar with the environment of the library.It demands quite a lot from the query to the required information to the acquisition process,which means people can not quickly locate the book or get book search route.In order to meet the needs in the library management,this paper designs and implements the automatic identification and location service system.This paper has done the following research work:(1)This thesis proposes a dynamic gradient matching K-nearest neighbor algorithm.First,the positioning accuracy in the dynamic Wi-Fi environment is greatly degraded and the performance is unstable.What's more,the redundancy in the database can lead to a low matching rate.The algorithm can enhance the anti-jamming capability of Wi-Fi positioning in the dynamic Wi-Fi environment.Meanwhile,the gradient featured fingerprint reduces the database redundancy and the secondary partition can improve the partition hit rate.The experimental results show that the algorithm has obvious advantages in improving the overall positioning accuracy,positioning efficiency and partition hit rate,and the heterogeneity of the equipment.(2)The thesis designs a dynamic joint tracking and navigation mechanism,which has high effectiveness in the Wi-Fi positioning in Wi-Fi blind environment.It also achieves continuous indoor positioning in Wi-Fi blind environment.At the same time,a real-time dynamic Dijkstra navigation algorithm based on reference fingerprint nodes is proposed,and the optimization of path planning between two positions is realized.The experimental results show that the algorithm has a significant effect on path planning length and time use.(3)The automatic identification and location service system is designed and implemented in the library management.This system can solve the problem of the low efficiency of searching and shelving books as well as the cumbersome process.This achievement provides reliable library information query,indoor positioning and navigation of practical tools for library warehouse administrators and visitors successfully.
