In order to improve the heating quality of residential district and increase?the working efficiency of the heating network staff, the system which can be used to adjust the balance of heating pipe network is presented. The hydraulic balance adjusting system based on Android uses the architecture of C/S and its development environment is built of Eclipse?and ADT. Besides, SQLite and SQL Server are used as system database. Furthermore, the object-oriented development method is adopted throughout the implementation process to achieve the functions of information management, hydraulic characteristic adjustment, heat load forecasting, new heat network hydraulic characteristics of forecasting and system management. The trend of the information parameters is demonstrated directly by the line chart in the information management subsystem. While in the hydraulic characteristic adjustment subsystem, it can analyze the current situation of the heating network by establishing the method of temperature control model and then generate scientific adjustment strategy, including the histogram of hydraulic parameters and textual description, to provide scient
