Real-time monitoring of ready-mixed concrete delivery with an integrated navigation system

摘要

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.
