  • In response to the urgent need of online meteorological service products in business, the construction of online production system of meteorological service products is carried out based on service integration. Details of the key technology is discussed, including dynamic service registration technology, product and service standardization, product service pipelined realization, the application of comprehensive regular operation rules in dynamic updating of parameters, and multi-level tasks scheduling. The system consists of server and client sides, and the server takes the duty of service interface development and release, while the client can be used for the management and operation of the task scheduling by all levels of the user.The WebGIS architecture is used in the weather service product online production system. The server is responsible for the development and management of the service interface, solving the problem of product production efficiency and standardize through distributed computing. It also packs the research and development of service component development module, service model creation module, service template development module, service configuration module, and service package module. The client together with the server side solves problems of system resource requirements and maintenance, also, the client achieves the function of task query, task management, operation monitoring, data statistics, user management, and parameter configuration.The construction of service-based system is discussed in detail too. The whole system is composed of services, using a dynamic, distributed and service-oriented system framework. Components are the core of the whole architecture, and they use and provide a variety of services that can be found. The service is the consistent window for the entire system, the product is a service, the interface is a service, and even the whole system is a service. Users do not need to care about the use of the system hardware and software deployment, product specific production steps and data sources. Users only need to analyze requirements and use the service interface on-demand production or extract results of the interface.Dynamic expansion of services and flexible configuration are realized through the service dynamic registration technology. Business products, overall norms, upgrades, efficiency is guaranteed by the key technology of product and service standardization and product service pipelined realization. The application of comprehensive regular operation rules improves the flexibility of the product. Multi-level task scheduling processing technology solves the problem of the system cluster deployment and effectiveness.
