상용 RF 위치 센서를 이용한 네일건 부상 방지 시스템 개발

초록

This study experimentally evaluated the feasibility of a nail gun injury prevention system using the commercial RF positioning sensor module DWM1000. We designed the system to attach positioning sensors to the nail gun and the worker's opposite hand, generating an alarm when the distance and orientation between the two sensors exceeded a predefined threshold. In the experiment, we tested the case with increasing wooden board thickness (1.6 cm increments) between the sensor modules to analyze positioning accuracy. We derived a two-step error correction function through linear regression analysis. After applying the error correction function, the system was tested under conditions where a wooden board was positioned between the two sensors. The results showed a predicted value of 9.81 cm for an actual distance of 10.73 cm, corresponding to an error rate of approximately 8.61%.
