Abstract:Based on Radio Frequency Identification(RFID) principle, Sample Information Management System(SIMS) is built by integrating a high degree custom acquisition system and newly designed RFID tags. The basic working principle and design ideas are introduced in detail. The proposed system can solve the problem of low recognition rate for bottled and boxed liquid, and substantially increase the recognition rate of ordinary material samples. The flowchart of the program design is put forward. The identification system is designed for the sample management from the perspective of efficient identification, scientific management and simple application.
