The Holographic Perception Convergence Platform is established around urban security, utilizing technologies such as video structured analysis and pervasive access of IoT smart hardware to ensure urban safety, achieving data convergence, parsing and recognition, and intelligent operation and maintenance detection functions. As a nexus for data convergence and governance, it aggregates data from public, social, and professional domains into the holographic perception platform of the sensing network, realizing full lifecycle supervision of data-driven governance, monitoring, acceptance, application, and operation and maintenance.
