Design and development of tractor hangar information management system based on RFID and GPS
In view of the huge amount of data generated in the management process of some large tractor hangars,the traditional management method of manual input is inefficient,high cost and low reliability,and a set of tractor hangar information management system is designed and developed in combination with the Internet,sensors,intelligent positioning and other technologies.The system is mainly divided into mobile terminal and hangar end development,the mobile terminal uses GPS for tractor outdoor positioning,calculates the tractor working area and other information combined with the tractor working width,and develops the mobile terminal human-computer interaction interface.At the hangar end,the hardware circuit of radio frequency identification(RFID)is designed first,and then the indoor positioning of the tractor is carried out using the Landmarc positioning algorithm,and finally,the tractor online management visualization platform is developed by integrating the environmental parameters in the hangar and the operation information uploaded by the mobile terminal.In order to verify the feasibility of this system,the positioning simulation of Landmarc algorithm,the verification of the accuracy of the operation area calculation,and the packet loss test of data upload are carried out,and the test results show that the average error of the indoor positioning of the tractor is 1.06m,which can meet the requirements of judging the tractor parking space,and the average error of the operation area calculation is 4.17％,which can meet the needs of actual operation.The success rate of data storage is 97.70％,which can realize the storage of various data.
