Abstract: At present, most RFID readers only read and write a general range, rather than an accurate distance reading and writing. This makes the application unable to determine the correct application of scenarios, and when found that the distance can not meet the requirements to read and write, you must manually change to the application of this inconvenience. To solve this problem, the paper presents an optimized strategy, namely that the RFID-based auto-loop gain adjustment algorithm is applied to RFID-based transportation management systems of the ore shipped in the automatic recognition of vehicle segments.
