Tracker For Logistics Based On Secondary Radar Detection

With the development of logistics, tracking equipments are needed and developed in times. At the very begging, barcode is used in logistics. Later with the use of RFID technical, logistics information upload becomes more safe and efficient, but it can’t upload information real time.This thesis gives a design of tracker that is fit for logistics. In the design, GSM/GPRS communication technical is used as access network, GPS receiver is used to get position. Sensors such as temperature and humidity sensor, G-sensor, pressure sensor, light and proximity sensor are used to collect real time information. Especially, a new method of airport secondary radar detection is design, so when the equipment arrives at the airport, it will turn off transition part automatically. With these designs, the tracker is fit for air transport.
