AI Technical Summary
Technical Problem
The existing electronic paper tags have unstable signal transmission when they are far from the access point, resulting in untimely image refresh and affecting operational stability and accuracy.
Method used
A distributed base station system is adopted, which uses power line carrier technology to connect base stations and nodes. Nodes and tags use BLE combined communication to realize broadcast connection requests and data transmission.
Benefits of technology
It reduced the cost of base station construction, saved maintenance manpower and resources, and improved the stability of signal transmission and the accuracy of command execution.

Abstract
The application relates to the technical field of electronic paper and discloses an electronic paper picture transmission method, system and device based on a distributed base station. When a first label receives a picture brushing instruction, the method compares a to-be-brushed-picture label id in the picture brushing instruction with a self label id; if the label id of the first label exists in the to-be-brushed-picture label id, a first connection request is broadcast to a base station to initiate connection; when a first node corresponding to the first label detects the first connection request, the first connection request is forwarded to the base station, so that the base station acquires first picture data corresponding to the picture brushing instruction and sends the first picture data to the first label; when the first label receives the first picture data, picture brushing is completed according to the picture brushing instruction. The application greatly reduces the cost of base station construction, saves manpower and material resources for daily maintenance, and improves the stability of signal transmission and the accuracy of instruction execution.
