To address the issue of uncontrolled vibration in concrete construction. A control system with visual and auditory feedback functionality is developed. Worker posture is represented by Euler angles and size of body to establish palm positioning model. Combined with the construction characteristic of the vibrator, the position relationship between the worker head and vibrator tip is established using the palm as medium. The working state judgment algorithm for vibrator is proposed using the variation characteristic of input current in vibrator to calculate the vibration duration and insertion depth. Based on these algorithms, developing devices are suitable for manual vibration to collect calculated parameters. The developed software system accesses parameters from on-site devices to evaluate vibration quality based on energy transfer model, and sends the construction warning information to site through visualization model and the main control device installed on safety helmet. The application proves that the developed feedback control system is helpful to improve the vibration quality.
