Method for updating content of electronic label and device

A method for updating a content of an electronic label, applied to a first electronic label, the method comprising:

• receiving a status query request from an electronic label content updating device;
• in response to the status query request, sending status information of the first electronic label to the electronic label content updating device;
• receiving first object information of the first target object determined according to the status information of the first electronic label sent by the electronic label content updating device, wherein a distance difference between the first target object and a first coordinate position where a first electronic label is located is within a preset distance range;
• and
• displaying the first object information of the first target object;
• wherein, in response to the status query request, sending the status information of the first electronic label to the electronic label content updating device comprises:
• in response to the status query request, sending an electronic label identifier of the first electronic label to the electronic label content updating device, wherein the electronic label identifier uniquely identifies the first electronic label;
• and
• controlling a status light in the first electronic label to flash.

An electronic label content updating device, comprising:

• a memory and at least one processor, wherein the at least one processor is configured to read and execute instructions stored in the memory to perform:
• obtaining first object information of a first target object, wherein a distance difference between the first target object and a first coordinate position where a first electronic label is located is within a preset distance range;
• and
• sending the first object information of the first target object to the first electronic label, and controlling the first electronic label to display the first object information of the first target object;
• wherein the at least one processor is further configured to read and execute instructions stored in the memory to perform:
• determining the first coordinate position of the first electronic label and a first electronic label identifier of the first electronic label, wherein the first electronic label identifier uniquely identifies the first electronic label;
• determining that there is the first target object whose distance difference from the first coordinate position is within the preset distance range;
• determining the first object information of the first target object;
• and
• establishing a first corresponding relationship between the first electronic label located at the first coordinate position and the first target object;
• wherein the at least one processor is further configured to read and execute instructions stored in the memory to perform:
• obtaining an image of the first electronic label, wherein the image comprises a mark point configured to represent a coordinate position of the first electronic label;
• and
• determining the first coordinate position of the first electronic label according to the coordinate position represented by the mark point.
