Construction of an Integrated Management Platform for Remote Maintenance and Content Updates of LED Displays
ZENG Xiaoting
Abstract：With the acceleration of urban informatization,the large-scale deployment of outdoor LED displays has exposed two major challenges in traditional manual operation and maintenance(O&M)and offline playback control models:low management efficiency and significant security risks.To address these issues,this paper designs and implements a system comprising an integrated management platform for remote maintenance and content updates of LED displays.The system employs a cloud-edge-device collaborative technical architecture.It utilizes an intelligent terminal controller with ARM+FPGA heterogeneous computing capabilities to achieve real-time sensing of display microenvironment parameters and deep-level control of underlying hardware.A lightweight MQTT communication protocol was designed to address high-concurrency access from numerous terminals in weak network environments.Software-wise,a comprehensive management system was established,incorporating intelligent fault diagnosis,multimedia content orchestration,and multi-level security review.
