Abstract:With the development of urbanization in China, the underground drainage network system becomes more and more large and complex. The traditional drainage management mode is facing huge challenges, and smart drainage system has been emerged. Based on the analysis of the current situation of the drainage network in a central city of South Henan Province, and combined with the local actual situation and the business needs of pollution control and waterlogging prevention, a smart drainage network system for the central urban area of a city is established. The contents of the smart pipeline network platform are divided and described in detail. And the stationing measures and monitoring scheme of divided area and monitoring in turn are innovatively proposed. Finally, the application effect of this smart drainage pipeline network system is analyzed and the future development direction of the platform is put forward in order to provide the valuable reference for the smart construction of drainage industry in the future.
