Radio frequency identification system test board

Abstract

The invention discloses a radio frequency identification system test board. The test board comprises an upper computer, a PLC controller, a conveyer, an antenna revolving table and an antenna rotary table, wherein the conveyer is used for transmitting a radio frequency tag; the antenna revolving table is used for adjusting the directions of a transmitting antenna and a receiving antenna; the conveyor is driven by a variable frequency motor; the antenna revolving table is arranged above a conveyer belt of the conveyor; a brake motor is connected with a rotary table transverse shaft through a two-stage speed reducer and is used for adjusting the pitch angle of the antenna; a servo motor is in transmission connection with the antenna rotary table through a driving mechanism which is used for driving a first antenna turntable and a second turntable to rotate synchronously and reversely, and is used for adjusting the azimuth angles of the transmitting antenna and the receiving antenna; the transmitting antenna and the receiving antenna are connected with the upper computer through a measuring device; and control ends of the variable frequency motor, the brake motor and the servo motor are connected with the output end of the PLC controller. The test board can simulate a practical application scene to perform a comprehensive test on the radio frequency tag and has high automatic degree.

Description

technical field [0001] The invention belongs to the field of automatic detection devices of radio frequency tags, and in particular relates to a radio frequency identification system test platform. Background technique [0002] Radio frequency identification technology is widely used in industrial automation, logistics management, transportation management, anti-counterfeiting, security management and other fields. Although the radio frequency identification technology is relatively mature and there are many corresponding products, there are still few tests on the radio frequency identification system. In actual use, the installation position of the radio frequency identification system reader, the attachment position of the label, and the moving speed of the item must be tested. Repeatedly installing, testing, then removing, and reinstalling in another location for subsequent testing is time consuming and difficult. Therefore, there is a need for a radio frequency identifi...
