METHOD AND DEVICE FOR RECOGNIZING VEHICLES SEQUENCE

摘要

A method for recognizing vehicles sequence is disclosed. The method is implemented based on low level reader protocol (LLRP) scheduling, and includes: when vehicles trigger a first coil, the vehicles are inventoried circularly and the value of received signal strength identification (RSSI) of each vehicle in each inventory result is accumulated until the vehicles trigger a second coil (101); the vehicles sequence is determined according to the size order of the accumulation of RSSI value for each vehicle (102). A device for recognizing vehicles sequence is also disclosed. Using the method and device, when multiple vehicles appear in the coverage of an antenna simultaneously, the vehicles sequence can be recognized correctly.
