Position identification method and system

Abstract

A position identification method and system are provided. The position identification method is applied to a position identification system. The system includes: a power supply guide rail provided with positioning mark information, and an electronic shelf label installed on the power supply guide rail and provided with a photoelectric geminate transistor. The electronic shelf label reads corresponding positioning mark information on the power supply guide rail on the basis of the photoelectric geminate transistor, and determines a target position on the power supply guide rail according to the positioning mark information. By means of determining a target position of an electronic shelf label on a power supply guide rail according to positioning mark information of the electronic shelf label on the power supply guide rail, a self-positioning capability of the electronic shelf label is realized at a low cost, and the accuracy of positioning can be ensured.
