Method and apparatus for collecting drill bit performance data

The drill bit and sampling drill bit and related sensor data method. Is drilling into the formation drill bit (200) comprises a drill body and shank (210). The shank further - comprising through the rock drill tail's inner diameter is; and configured to receive the data analysis module centre hole. Data analysis module comprises multiple sensor (340), memories (330) and a processor (320). The processor is configured as a communication, comprising a through a plurality of sensors for containing the sensor, data analyzing the sensor data to form a locating degree, and at least one self-adaptation threshold value the data sensor, and wherein by the data with in comparison. The method comprising, wherein is in a patterns and a sampling multiple containing the sensor data of the drill bit and related rich parameters, and converting of the sample patterns.
