Abstract:Rural water supply projects in Guizhou's mountainous areas face challenges such as scattered distribution, complex management, and low informatization. To enhance supervision, operation, maintenance, and service capabilities, this study developed a provincially coordinated information management platform for rural water supply security projects. The platform integrated Internet of Things (IoT) and big data technologies, establishing an intelligent sensing network spanning water sources, pipelines, water plants, and end-users, enabling fully digitized supervision across the entire process. A three-level collaborative management system (provincial, municipal, and county) based on cloud-edge collaboration and microservice architecture was designed, forming a business closed-loop encompassing monitoring and early warning, decision-making and response, and effectiveness evaluation. The platform incorporated two core modules—provincial standardized information management and intelligent monitoring and early warning for water plants—providing comprehensive coverage from macro-level supervision to on-site operations. Practical applications demonstrated that the platform effectively improved water supply security and operational efficiency while reducing pipeline leakage, offering a systematic solution for digital and intelligent management of rural water supply in mountainous regions. Its standardized architecture and collaborative mechanisms provide a replicable reference for similar contexts.
