According to the real-time monitoring method and system for the state of the drilling tool in the cast-in-situ bored pile construction disclosed by the invention, the characteristics in the working state information of the drilling tool in the cast-in-situ bored pile construction and the corresponding characteristic values are analyzed, and then the analyzed data are judged and fused to determine whether the current drilling tool has errors or not, so that the accuracy of monitoring the state of the drilling tool in the cast-in-situ bored pile construction is improved. And when error information of the drilling tool exists, the drilling tool is adjusted in time, and the precision of the cast-in-situ bored pile is improved. 本发明公开的一种钻孔灌注桩施工钻具状态实时监测方法及系统，通过对钻孔灌注桩施工钻具的工作状态信息中的特征以及对应特征值进行分析，再将分析出来的数据进行判定以及融合，确定当前钻具是否存在错误，当存在钻具错误信息时，及时对钻具进行调整，提高了钻孔灌注桩的精度。
