Aiming at traditional Chinese medicinal materials traceability problem of type
quality and weight in all aspects of planting
producing and circulation
propose overall structure of traceability system of traditional Chinese medicinal materials. Design a high-precision weighing sensor node
which has the function of reading RFID tag value from medicine packing bag and weighing. At the same time
temperature compensation is carried out on sensor node using artificial neural network. Experimental results show that the nonlinearity of weighing sensor reaches 0. 285 % after compensation
its weighing precision is high and has great application prospect in traceability system of traditional Chinese medicinal materials.
