Active tag identification precision test method based on normal distribution

Abstract

The invention discloses an active tag identification precision test method based on normal distribution. The method comprises the following steps: arranging active tags and an induction area, testing trigger moments of a plurality of active tags and calculating deviation values of the trigger moments, calculating a standard deviation of the deviation values of the plurality of active tags, and discriminating identification precision according to a normal distribution principle. The beneficial effects of the invention lie in that the method tests the timing precision of the induction timing system based on normal distribution, reads and records the triggering time of each active tag through the induction device, and calculates the standard deviation between each triggering time and the average triggering time through a large number of repeated test samples, the upper limit and the lower limit of the confidence interval of the given probability to which the deviation value between the output value and the true value of the induction timing system belongs are taken as the timing precision of the system, the theoretical basis is sufficient, the operation is simple, and the accuracy of the active tag precision interval can be obtained through a table look-up method.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a method for testing the identification accuracy of active tags based on normal distribution. Background technique [0002] In the sports industry, the camera timing system at the finish line is likely to cause disputes over the results of the competition due to errors in human recognition. Even for sprint events, replays and other methods cannot resolve competition disputes. With the rapid development of science and technology, high-speed radio frequency identification technology is more and more widely used in various fields of life. Especially in the sports industry, active tag timing systems can more accurately record athletes' game data. However, the inductive timing system of the active tag must undergo repeated tests before use to determine that the timing accuracy of the entire system meets the usage requirements. At present, the accuracy test met...
