The invention provides a system and a method for testing electronic label sensitivity. The system comprises a device used for keeping an electronic label identification distance and an angle be invariant, and an electronic label sensitivity test device, wherein the device keeps the identification distance of an electronic label and the angle be invariant through adjusting height of a liftable support and a liftable platform and the angle between test antennas. The method mainly comprises steps that a query Query command is sent through a radio frequency transmitter under nominal center frequency of a tested electronic label to the tested electronic label, power scanning is further carried out in a 0-27dBm scope, and power stepping is 0.25dBm; the response data of the tested electronic label for the query Query command is acquired through utilizing a radio frequency receiver, if the response data passes CRC verification, label identification is determined to succeed, a minimum emission power value for label identification success is recorded in a test, and a sensitivity value of the label is further calculated.
Description
technical field [0001] The invention relates to the field of measurement technology, and more particularly, to a system and method for testing the sensitivity of an electronic tag based on a device that keeps the identification distance and angle of the electronic tag constant. Background technique [0002] With the continuous development of the national electric power industry, the demand for efficient and precise management of power assets in the power grid system is getting higher and higher. In this regard, the power grid system has introduced electronic tags based on radio frequency identification technology (Radio Frequency Identification, RFID) to achieve efficient and accurate management of power assets. In order to ensure that these electronic labels can be accurately identified in actual use, strict tests must be carried out at each stage of label development. Among them, the test of label sensitivity is the top priority of each test, which is directly related to ...
