The importance of monitoring the rolling quality of road rollers
With the development of information technology, informatization and digitization have gradually penetrated the entire lifecycle of engineering construction and operation. In recent years, the rapid development of Internet of Things technology and Mobile technology has once again promoted the new application of high-precision measurement, positioning technology and intelligent technology in construction process control. These innovative products provide scientific and effective means to control the quality of the construction process, improve work efficiency, and ensure construction safety.
Rolling compaction construction is one of the main construction measures commonly used in infrastructure projects such as hydropower stations, airports, high-speed railways, and transportation, including soil and stone compaction construction, concrete compaction construction, etc. Compaction is the core indicator for evaluating the quality and results of rolling construction, while the thickness of the rolling layer, the number of rolling passes, and the frequency of vibration are the key control indicators for the quality control of the rolling construction process. For a long time, traditional quality monitoring methods have adopted the method of "manually measuring the thickness of the rolling layer, recording the number of rolling passes, and organizing sampling testing for compaction degree after rolling is completed", which not only has low work efficiency but also cannot comprehensively evaluate the rolling quality. In recent years, digital products and solutions for rolling monitoring based on GPS and related sensing technology have gradually emerged, but the cost is high and Chinese enterprises do not have independent intellectual property rights in core technologies.
The Application of Rion Accelerometer in the Monitoring and Analysis System of Rolling Quality
The Rion Technology accelerometer monitors the roller in the real-time monitoring and analysis system for rolling quality. It uses the vibration frequency and amplitude of the accelerometer to monitor the roller's rolling construction speed, speed, and excitation force in real time, whether it vibrates according to the requirements, whether the vibration meets the design requirements, and can also calculate the excitation force of the roller at that time through the amplitude and frequency. The vibration frequency is the number of vibrations within a period of time, and the vibration amplitude is the maximum acceleration per unit time. The sensor is installed on the roller of the press, uploading data in real-time, providing construction guidance and abnormal warning of rolling speed, layer thickness exceeding standards, and assisting the driver in driving and control.
