Abstract:At present, China’s county-level water informatization is still in its infancy, there are a large number of common technical and functional needs among different business applications. In order to realize the rapid establishment of business system, reduce development and maintenance costs and meet the demand of rapid technology iteration in the future, this paper puts forward a micro-service architecture-based framework of countylevel lightweight intelligent water management platform on the basis of actual development of county-level regional development and systematic sorting of water utilities business, water users, associated synergy systems in county areas. To solve the core problems in country-level water management, the intelligent management platform takes core business as the functional traction, professional model and numerical algorithm as the intelligent engine, and personalized customization as the user expansion. By functions decomposition of the business processes of the water system and commonality extraction and merger, a microservice group that could be shared by each business system is constructed. Based on a unifified application support platform, cross-system data, process and business synergy are realized, which can reduce repeated development and investment of local governments in informatization construction, and improve management and service levels of county water industry.
