The invention provides a portable RFID (Radio Frequency Identification Device) product parameter testing device. The portable RFID product parameter testing device comprises a coupling interface, a power detection device and a control unit, wherein the coupling interface is suitable to be connected to a reader and an antenna, and is used for communicating the reader with the antenna and acquiring an incident power signal transmitted by the reader and a reflected power signal received by the antenna; the power detection device is connected with the coupling interface, and is suitable for converting the incident power signal into an incident voltage value, and converting the reflected power signal into a reflected voltage value, and outputting the incident voltage value and the reflected voltage value; and the control unit is suitable for receiving the incident voltage value and the reflected voltage value, performing calculation to obtain a parameter including at least one of transmitting power and transmitting frequency of the reader and a standing-wave ratio of an antenna end, and outputting the parameter. The portable RFID product parameter testing device has the characteristics of online detection function, arrangement of an embedded battery and an LCD display screen, convenience in field maintenance, high measuring accuracy and the like.
Description
technical field [0001] The invention relates to the technical field of radio frequency communication detection, in particular to a portable RFID product parameter testing device. Background technique [0002] Today, RFID technology has been used in various industries. A conventional RFID system consists of the following four parts: a tag, an antenna, a reader, and a radio frequency cable connecting the antenna and the reader. ) and the matching degree (standing wave ratio) of the antenna end to detect the faults and deal with them in time. At present, some manufacturers have integrated some power and standing wave ratio detection circuits in the reader, but to view the corresponding detection data, an external computer (and corresponding test software needs to be configured), and few devices can read tags. At the same time, monitor the changes of the corresponding indicators. [0003] In addition, there is no separate professional equipment for detecting the emission inde...
