Development And Application Of Smart Pipe Network Data Acquisition System Based On RTK And Mobile GIS

In recent years,with the continuous improvement of China’s urbanization process,the construction of urban heating network systems has been continuously improved,and the acquisition of basic data for heating network networks has become one of the important research directions in the construction of heating network information.After analyzing the research status at home and abroad and conducting an in-depth investigation of the construction needs of heating network companies,this article understands that most heating network companies have problems with data collection.Aiming at these problems,the data types and collection methods of data collection for heating pipe network are studied.The main research contents of this article are as follows:1)Analyze the overall situation in the context of the mobile Internet,and carry out the overall design of the system based on the actual conditions and overall needs of the urban heating network system,and based on the characteristics and types of relevant data of the urban heating network system The required data structure is reasonably designed,and a set of data collection and management system for urban heating pipelines suitable for Android mobile applications is proposed.2)According to the data precision requirements of urban heating pipe network,the RTK measurement method based on GNSS receiver is selected as the main measurement method of the system,so as to obtain the high-precision spatial position information of the upper and lower entities of the heating pipe network,and carry out the Bluetooth communication module.The design enables Bluetooth communication and information interaction between the GNSS receiver and the Android mobile device.3)Based on Android Studio and mobile GIS,develop mobile application of urban heating pipe network data collection system based on Android system,develop PC-based data management system based on Visual Studio,realize multi-functional collection of different types of urban heating pipe network data,Professional application functions such as real-time two-dimensional map display,data addition,deletion,modification and retrieval,data caching,and data management.The application practice shows that the data acquisition system of urban heating pipe network is reasonable in design,clear in silk path,complete in software function and stable in operation,and achieves accurate acquisition of location information of ground objects,which improves the efficiency of data collection and management of heating pipe network system.It satisfies the application requirements of data management and pipe network maintenance of heating pipe network company,and has a good application and promotion prospect.
