The Design And Implementation Of The Water Supply Network Inspection System Based On Android Smartphones

Urban water supply networks and facilities are complete, functional soundness, direct impact on the living standards of urban residents, related to the sustainable and healthy development of urban economy and society. The traditional network model cannot meet the urban conservation inspections rapid development and the need for rapid increases in people’s lives, the use of information technology, development of water supply pipe network inspections system, water supply facilities inspections management, information technology, intelligence, in order to achieve the existing water supply fundamental changes in the pipe network patrol patterns to enhance inspections conservation management level, to improve the technical capacity of the outdoor inspectors regulation to solve the bottleneck of the business sector and the real-time data exchange of inspectors.Based on the urban water supply networks inspections work characteristics, ways and means for inspections conducted research, combined with the current development of smart phones, mobile communications and computer technology, we propose a Android-based smartphones, GPS,3G wireless communication technology, GIS (geographic information system) technical inspections of the water supply network and urban water supply network combining geographic information.First, this paper discusses the development background of Android-based smartphones water supply network inspections systems research status of the system to solve the problems of the statements from the functional requirements of the system and non-functional requirements described in two ways need to question the system, the system functional requirements of this section, use the system business process diagrams and system is described in detail the use case diagram.After the needs analysis, the paper supply pipe network architecture design systems based on inspections Android smartphones were analyzed. According to the results of the system needs analysis, the proposed mission-critical systems, describe the system design principles from the system advanced, system openness, scalability, security, and business adaptability five aspects. Based on the design principles, the system architecture is divided into technical architecture, functional architecture and security architecture. Technology architecture describes the system structure and the technical means dividing the phone side and the central server uses. The functional structure which describes the system functional modules composed and affiliation between functional modules. Security architecture description of the system on which the security level has been designed.On the basis of the system architecture design, detailed design of Android intelligent mobile phone water supply pipeline inspection system based on. This part according to the server and the mobile phone terminal data exchange process to design the system, analysis of system model structure, describe the main realization of each layer of content three layer architecture, complete the hierarchical Android intelligent mobile phone water supply pipeline inspection system based on sketch. According to the divided way smart phone terminal system and server management subsystem, function point of some key function modules in the system description, detailed discussion and design of process, draw the flow chart of the system process.The fourth part describes the realization of the system; first introduced the hardware and software needed for system development environment, and then describes the Android mobile client focus and server-side implementations of data interaction inspections, given the specific implementation code and the specific interface. Then the manner described in the code inspections of several typical business phone system features side and server side, gives concrete realization screenshot function. Finally, a brief introduction of the system test.Finally, the conclusion would have been part of the post-Android-based smartphones water supply pipe network systems need to improve inspections improved part of the explanation, the next step is proposed to perfect a few key points.
