Application of Wireless Communication in Road Intensity Detecting System

Road intensity is an important performance parameter and evaluation index of concrete road quality. During the construction of road infrastructure, the implementation of road intensity testing has become very necessary. So as to meet the needs of remote testing, wireless communication was adopted based on CC2430. LabVIEW was used as the system’s development platform of upper computer. Through the signal collected by the pressure sensor combined with signal conditioning circuits, functions of various parts were designed to analyze the relevant parameters of the road intensity. The related data of concrete road was measured and sent to upper computer through wireless communication module, at the same time, the statistics data was analyzed with regression analysis by virtual instrument software. The functional relations between compressive strength and tensile strength of the road was found and thus it provided an important basis for the quality of road management and road maintenance.
