Seamlessly link multiple IoT devices to the cloud, oversee them through an intuitive interface, incorporate and evaluate data, and leverage open functionalities for innovative services. The issue of device fragmentation poses significant challenges, as diverse protocols and complex standards lead to prolonged interconnection times. Efficient management is hindered by the lack of unified access across different networks, resulting in unstable connections and isolated devices, while event processing remains rigid. With robust remote operation and maintenance (O&M) capabilities, personnel can effortlessly gather device fault logs, identify issues, restart hardware, or revert devices to their original settings, significantly lowering labor expenses associated with on-site maintenance. This not only enhances operational efficiency but also paves the way for smoother device interoperability in the future.
