Real-time Monitoring of Ready-Mixed Concrete Delivery with an Integrated Navigation System

چکیده
The escalating scale and growing complexity of ready-mixed concrete (RMC) delivery operations have challenged current methods for monitoring RMC delivery and dispatching truckmixers by two-way radio voice-based communication and experience-driven management. This paper describes an integrated navigation system, based on Global Positioning System (GPS)/Dead Reckoning (DR)/Bluetooth Beacon (BB) and Global System for Mobile Communication (GSM) technologies. The application of the integrated navigation system in tracking RMC truckmixers on and off Hong Kong construction sites is presented. The system performance in terms of positioning precision in tracking RMC truckmixers is analyzed. In addition, the readily available data of event times resulting from tracking RMC truckmixers is found conducive to high-end simulation modeling for productivity analysis and improvement in construction.

Performance Enhancement of GPS/INS Integrated Navigation System Using Wavelet Based De-noising method
Accuracy of inertial navigation system (INS) is limited by inertial sensors imperfections. Before using inertial sensors signals in the data fusion algorithm, noise removal method should be performed, in which, wavelet decomposition method is used. In this method the raw data is decomposed into high and low frequency data sets. In this study, wavelet multi-level resolution analysis (WMRA) techn...
