In the digital economy's rapid growth, this study aims to improve rural toilets using smart designs, enhancing public health emergency preparedness and addressing rural information asymmetry. By integrating environmental treatment, IoT, and smart detection technologies, seamless data interaction with big data platforms is achieved. The Smart Urban-Rural Cloud Platform enables intelligent management of rural public health emergency toilets. This system monitors rural epidemics, provides toilet hygiene feedback, and establishes a smart information platform for rural revitalization. It boosts rural smartness, information resource efficiency, and resident/tourist satisfaction, promoting balanced urban-rural information distribution, economic ties, and digital support for rural revitalization
