Core Drilling Breakthrough Detection for Cavities and Intermediate Layers

The breakthrough detection is segmented into multiple independent sensing channels: a first sensor detects mechanical breakthrough conditions, while a second sensor detects electrical breakthrough conditions. This segmentation allows the system to distinguish between different drilling situations (actual breakthrough vs. intermediate layer) by evaluating which sensor triggers the breakthrough signal, thereby improving measurement precision and preventing unnecessary re-drilling operations that waste time.

An intermediary control unit is introduced that receives signals from both the first sensor (mechanical detection) and the second sensor (electrical detection). This intermediary processes and evaluates both detection results before determining whether a true breakthrough has occurred. By using this intermediary layer, the system achieves more precise situation recognition and avoids false breakthrough detections that would prolong drilling time.

The sensing system is segmented into two independent but complementary detection channels: mechanical detection (first sensor) and electrical detection (second sensor). Each sensor handles a specific aspect of breakthrough detection, simplifying the overall system architecture while improving measurement precision. The control unit processes these segmented signals independently before making a final breakthrough determination.

The control unit is designed with multi-functionality, serving both as a mechanical signal processor and an electrical signal evaluator. This universal component consolidates the complexity by handling both sensor types within a single control unit, rather than requiring separate processing systems for each sensor type, thereby improving detection precision without proportionally increasing device complexity.
