Pseudo rock and analysis system using the same |
摘要 |
A pseudo rock includes a housing, a strain sensor, a three-axis acceleration sensor, a vibration generator and a controller. The housing has an average shape and size of rocks. The strain sensor detects a stress acting in positive and negative directions of each axis with respect to three-dimensional coordinates using the center of the housing as the origin. The three-axis acceleration sensor detects acceleration acting in each axis of the three-dimensional coordinates. The vibration generator produces vibration in a specific direction with respect to the three-dimensional coordinates. The controller converts respective detected values of the strain sensor and the three-axis acceleration sensor into vibration pulses of specific patterns and outputting the vibration pulses to the vibration generator. |

1. A pseudo rock, configured to be buried inside a mineral deposit or under ground, comprising:
a housing having an average shape and size of rocks existing inside the mineral deposit or the ground; a plurality of strain sensors provided in the housing and configured to detect a stress acting in positive and negative directions of each axis with respect to three-dimensional coordinates (X axis, Y axis, Z axis); a three-axis acceleration sensor provided in the housing and configured to detect acceleration acting in each axis of the three-dimensional coordinates; a vibration generator provided in the housing and configured to produce vibration in a specific direction with respect to the three-dimensional coordinates; and a controller provided in the housing and configured to convert respective detected values of the strain sensors and the three-axis acceleration sensor into vibration pulses of specific patterns and outputting the vibration pulses to the vibration generator. |
