Design And Realization Of Taxi Inspection System Based On Internet Of Things Technology

This thesis discussed the principles and key recognition technology in the taxi inspection work based on the ZigBee short-range communications networking technology and color feature recognition.Currently,taxi inspection work is mainly done through RFID radio frequency identification technology,or video license plate recognition,these two technologies have obvious defects.This paper summarizes and analyzes the existing taxi recognition technology,based on the technical aspects of the problem for WSN applications,wireless identification,taxi licenses and other electronics in the taxi sector are explored and studied.IEEE802.15.4 ZigBee is based on a short-range communication technology,its application environment is mainly transmitted sensor data collected medical,industrial and mining enterprises,but the case for the motion of the vehicle is less common.The CC2530 ZigBee chips were tested concurrent communication,interference,relevance and speed of the transmission rate to demonstrated the feasibility in a taxi.Vehicle characteristics recognition technology is relatively mature,but it is mainly used in the vehicle 's license plate information extraction.This papaer Based on the GUANGZHOU taxi's characteristics,carried on the front dome feature recognition,according to vehicle characteristics;movement of vehicles on color recognition,the front of the taxi were divided into three parts,the best part of taking color consistency as the main color of the vehicle,for the preservation of the taxi basic color library comparison.At the same time,also according to this Peugeot taxi bumper coating are silver,as a second selection criteria,to further improve the recognition rate of the cab.The existing license plate recognition technology and wireless identification technology in the field of the taxi were analyzed and compared to propose the use of wireless electronic identification feature recognition of license plates and vehicle licenses video comparison of ideas,by means of information will be needed before labor,on-site verification brought a lot of work into electronic license plate reading system for ZigBee and physical contrast license plate automatic video recognition within a certain time frame,exclude most legitimate rental vehicles,simplifying the existing security Examiner workflow,reducing the intensity of the work.This paper discussed how to build a color feature recognition technology and ZigBee short-range communication based taxi inspection management platform,and get validation in the actual test run.
