Adapting Traceability System to Origin Positioning System for Agricultural Product from an Electronic Scale Using GPS

摘要

To overcome the limitations of current agricultural products traceability information obtaining methodology, we developed the OPSAP (origin positioning system of agricultural product) with electronic scales. The positioning system is a software model working with the electronic scale and providing objective location information for the whole traceability system. The electronic scale not only has the weighting function, but also provides a method for determining location where the scale positioned. This article establishes the OPSAP and changes traceability system made to support the TSAP (traceability system of agricultural product). Together, the two modules provide customers the unique ability to obtain the agricultural products' origin information through the traceability system. The application experiments showed that this was an effective way to complete agricultural products traceability chain.
