| Abstract: | Agricultural products traceability system is designed and implemented based on LPC1766 central processing unit to overcome the difficulties of tracing the origins and verifying the flow in the circulation phases.The hardware circuit includes LPC1766 core circuit,power,A/D,RFID interface,Ethernet interface.The function of weighing,electronic trading,product tracking,RFID identity recognition,two-dimensional bar code printing is implemented based on keil μVision3 IDE platform,including distributed control by means of wireless UDP.The results show that the system has good usability and high precision and improves management level,and implements effective tracing and tracking of agricultural products. |
| Keywords: | circulation traceability tracking control LPC1766 |
