The MK926 accelerometer is used for monitoring and analyzing the compaction of rollers.
1. The Importance of Monitoring the Quality of Roller Compaction
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 IoT technology and mobile technology has once again promoted the innovative application of high-precision measurement, positioning technology, and intelligent technology in the control of the construction process. These innovative products provide scientific and effective means for controlling construction process quality, improving work efficiency, and ensuring construction safety.
Compaction construction is one of the main construction measures commonly used in infrastructure projects such as hydropower stations, airports, high-speed rail, and transportation, including soil and stone material compaction construction and concrete compaction construction. The compaction degree is the core indicator for evaluating the quality and results of compaction construction, while the thickness of the compaction layer, the number of compaction passes, and the vibration frequency are key control indicators for quality control in the compaction construction process. For a long time, traditional quality monitoring methods have used 'manual measurement of compaction layer thickness, recording the number of compaction passes, and organizing sampling tests for compaction degree after compaction is completed,' which not only has low work efficiency but also cannot comprehensively evaluate compaction quality. In recent years, digital products and solutions for compaction monitoring based on GPS and related sensing technologies have gradually emerged, but they are costly, and Chinese enterprises do not possess independent intellectual property rights for core technologies.
2.MK926 AccelerometerUsed for the Roller Compaction Quality Monitoring and Analysis System
The MK926 accelerometer plays a role in the 'real-time monitoring and analysis system for compaction quality' by monitoring the roller compactor. It uses the vibration frequency and amplitude of the accelerometer to monitor the compaction speed, velocity, and excitation force of the roller compactor in real-time, checking whether the vibration meets the requirements and whether the vibration conforms to the design values. It can also calculate the excitation force of the roller compactor at that moment through amplitude and frequency. (Vibration frequency is the number of vibrations within a period, and vibration amplitude is the maximum acceleration per unit time. The sensor is installed on the roller's drum, uploading data in real-time, providing construction guidance and abnormal early warning information for compaction speed and layer thickness exceeding standards, assisting the driver in operation control.)
