Research And Design On Machine After-Sales Service Management System Supported By The Offline Application Technology

During the NPC & CPPCC of 2015, the China government report pointed out that our manufacturing industry must develop toward to innovation, high - end, high added value and green direction. The industry should attach importance to manufacturing industry development mode innovation, including the network, digital, intelligent and service, to make our country manufacturing industry shift from production type to production service.Based on the importance of manufacturing service innovation in the whole value chain, combining with the application of traditional after-sales service management system in the construction machinery industry, and using the Web offline application technology, this article gives detailed analysis and design for the ZTJ group Tunnel Boring Machine(TBM) after - sales service information management system. The main research content including:First of all, according to the research of ZTJ group’s requirements, this article gives detailed analysis for business requirements, functional requirements and performance requirements, etc. Combining with the TBM after - sales service features and the current problems of after - sales service information management, this article designs a new after-sales service information management system based on B/S architecture. It could manage all the information in the process of the whole after-sales service, which will improve the management efficiency.Secondly, during the analysis of the system applications environment requirements, to meet the situations of no network or network instability, this article designs offline mode. Currently, there are two kinds of offline applications, desktop applications and web applications. In order to achieve better cross - platform - ability, reusability, and obtain a better user experience, this article adopts the way of the Web offline applications.In the end, this article implements the basic business functions and offline application operation of the TBM after - sales service management system. The offline application system party adopts HTML5 offline technology:The offline caching of resources is based on HTML 5 Cache Manifest mechanism, the offline data storage is based on IndexedDB, and the offline data upload is based on the Ajax asynchronous request mechanism.
