The management system for traditional manual and semi-automatic barcode has disadvantages and shortcomings of the real time and convenience of the work, the dynamic tracking management system for samples based on RFID technology is designed. The functions of accurate positioning, dynamic tracking, automatic updating information and wireless upgrading for the electronic label through the application system are realized. The system is composed of activator, semi-active electronic tag, reader and application system. Adopting low power consumption "design, the whole electronic tag has a sleep current of 6. Using the anti-collision algorithm, when 200 tags are excited at the same time, the average missed read rate is 0.5% and the misjudgment rate is 0%.
