The IoT sensing system and integrated service platform independently developed by Capinfo, which was built on the new reproducible and propagable foundation of Beijing “unified management with one network” for data access, aggregation and application demonstration”, can provide basic support for coordinated management of IoT sensing devices and application services of sensing data within areas and fields. By keeping ledgers in for terminals and bases, we constructed an IoT sensing resource management system, where “unified standards are adopted, coordinated management is conducted, mutual recognition is realized and one code is available for general use”, to generally understand existing conditions and dynamic changes of all terminal sensing devices. This IoT sensing system and integrated service platform perform intensive management with “one terminal, one code”, facilitate full understanding of sensing devices through one ledger, and assist with leaders’ decision-making through multi-dimensional indicators.
