Study On Wireless Transmission Technology Of Vibration Compaction Dynamic Monitoring

With the rapid development of communication technology,especially the development of wireless network communication technology,more and more industrial applications accelerate the process of its informatization.In the monitoring and testing applications,wireless network transmission technology of many advantages provide an important reference tool for the high quality of the compaction monitoring.Engineering practices show that asphalt pavement construction technology is the guarantee of engineering quality.Yet all level of management,supervision personnel will detect the construction,it is limited to a certain frequency sampling.In the practical construction,different parts of the asphalt mixture in the process of mixing,rolling are different,a certain frequency detection is not comprehensive.In view of this,how to realize the construction of the real process control,achieve "seamless type,no blind spots "regulation,reduce the variability of the construction,has become a further problem for the builders.Proposed a kind of vibration compaction monitoring system based on 3 G services provided by China Unicom WCDMA network in this paper,to achieve the goal that the project management,supervision,personnel can monitor any vibration compaction construction site under the coverage of China Unicom WCDMA though PC platform getting access to the Internet.The vibration roller acceleration signals collected by the data acquisition system in the construction site,were analyzed by industrial computer.The vibration acceleration signals were converted to the value of the degree of compaction by the empirical formula and displayed in real time and the results were send to the remote monitoring PC platform.The project management,supervision of personnel on the construction site vibration compaction equipment and compaction of real time monitoring,data saving,which provides the basis for management decisions.Also supported the simple data retrieval,less and more compaction level alarm function.Though the internal testing and project construction trial,compared with the traditional compaction test method,with the function of wireless transmission compaction real-time system can not only effectively solve the traditional compaction test method of fewer sampling point problems,and solve the lag of the traditional detection method,the real-time detection improves the detection efficiency.Compared with the similar system,it’s real-time monitoring system,low cost,wide application,thus provide a good reference for the asphalt pavement construction process control and quality management.
