Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic delay detonators are used with precise delay time control, then blasting accuracy and vibration reduction are improved, but the complexity of connection and delay time setting increases
Solution Approach 1:
The system performs self-diagnosis by automatically detecting the connection status of each detonator through the trunk line and generating a connection status table, eliminating the need for manual connection verification and reducing setting complexity while maintaining precise delay time control
Solution Approach 2:
The connection inspection is performed before blasting operations to identify and correct connection issues in advance, ensuring that all detonators are properly connected and configured with accurate delay times before the actual blasting occurs
2Adaptability or versatility
If manual delay time setting is used for each detonator, then flexibility in blast pattern control is improved, but the time required for setup and error rate increase
Solution Approach 1:
The system provides feedback by displaying the connection status of each detonator and the assigned log counters, allowing operators to verify the configuration and make adjustments while maintaining flexibility in blast pattern control
Solution Approach 2:
The control device serves multiple functions including connection inspection, log counter assignment, and blast pattern control through a single integrated system, reducing the need for separate manual setting operations while maintaining versatility
3Reliability
If connection inspection is performed before blasting, then misfire prevention is improved, but the setup time and operational steps increase
Solution Approach 1:
The system performs automatic connection inspection by sending detection signals through the trunk line and automatically generating a connection status table, improving misfire prevention without requiring complex manual inspection procedures
Solution Approach 2:
Connection inspection is performed as a preliminary step before blasting to identify and correct connection issues in advance, ensuring reliable operation while the automated process minimizes the time and complexity added to the setup

AI summary
The present invention relates to an electronic delay detonator logging control device and a method therefor. The state and the connection of a plurality of electronic delay detonators connected in parallel and a trunk line are inspected before blasting so as to check for an incomplete connection and prevent a partial misfire, thereby inducing accurate blasting and enabling the stability of the electronic delay detonator to be improved. A log counter is assigned to the plurality of electronic delay detonators such that the plurality of electronic delay detonators can be blasted in desired blasting patterns or in sequence. In the event of a failure, a logging recovery mode is operated so as to recover connection information of the plurality of electronic delay detonators, and thus worker inconvenience is minimized during reconnection and re-registration operations such that work efficiency and convenience can be maximized.
