Problems solved by technology

[0004] However, in the current application process, when the vehicle is counted, the position of a certain vehicle may be in the blind spot that the UHF reader cannot recognize. At this time, if the RO first counts the vehicles behind, There will be a situation where the rear vehicles that have been counted will be deducted and the front vehicles will be released. That is to say, there is a defect in the existing application process that the order of the front and rear vehicles cannot be correctly identified. The serious consequences of deducting the wrong amount due to the deduction of the vehicle in front

Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The scheme of the present invention's identifying vehicle sequence is realized based on the scheduling of the low-level reading protocol (LLRP, Low Level Reader Protocol), the present invention's method for identifying the vehicle sequence, such as figure 1 shown, including the following steps:

[0045] Step 101: When the vehicle triggers the first coil, the vehicles are cyclically counted, and the RSSI value of each vehicle in each counting result is accumulated until the vehicle triggers the second coil;

[0046] Here, in actual application, the operation of vehicle inventory and corresponding deduction is performed after the vehicle triggers the two coils respectively. Specifically, when the vehicle triggers the first coil, the operation of vehicle inventory is performed, that is, to identify the vehicle Sequential operatio...

Abstract

The invention discloses a method for identifying vehicle orders. The method is implemented based on the dispatching of a low level reader protocol (LLRP) and comprises the following steps of: when a vehicle triggers a first coil, checking vehicles circularly; accumulating received signal strength indicator (RSSI) values of each vehicle in a checking result each time until the vehicle triggers a second coil; and determining the vehicle orders according to the magnitude orders of the accommodated values of the RSSI values of each vehicle. The invention also discloses a device for identifying the vehicle orders. By adopting the method and the device, the orders of the vehicles can be identified accurately when a plurality of the vehicles appear in an antenna coverage area at the same time.

Description

technical field [0001] The present invention relates to radio frequency identification (RFID, Radio Frequency Identification) technology, in particular to a method and device for identifying the sequence of vehicles. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) technology is a non-contact automatic identification technology. It automatically identifies the target object through radio frequency signals and obtains relevant data. The identification work does not require manual intervention. The RFID system includes readers and electronic tags. With the development of RFID technology, its application scope is also becoming wider and wider, and the most important application is the Electronic Toll Collection system (ETC, Electronic Toll Collection). [0003] In the actual application of the electronic non-stop charging system, the electronic tag is called an electronic license plate. The antenna of the UHF reader can identi...
