Electronic Detonator Local ID Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic blasting systems face challenges in verifying the presence and status of multiple detonators efficiently, particularly in large shots, due to the time-consuming process of serial ID verification and limitations in communication speed.
Innovation Solution
The system employs a local ID instead of the serial ID for verification and communication between detonators and the remote master controller, allowing for synchronous or asynchronous responses with shortened messages, thereby speeding up the verification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If serial ID verification is used to ensure unique identification of each detonator, then identification accuracy is improved, but communication time increases significantly
Solution Approach 1:
The patent segments the identification process into two distinct phases: a verification phase that uses shortened local IDs for rapid communication, and a confirmation phase that uses full serial IDs for accurate identification. This segmentation allows the system to benefit from both fast communication and precise identification without the trade-off present in traditional single-phase systems.
Solution Approach 2:
The patent introduces local IDs as an intermediary element between the master controller and detonators. These local IDs serve as temporary proxies for the full serial IDs during verification operations, enabling fast communication while maintaining the ability to confirm unique identification when needed. The local ID acts as a mediator that resolves the conflict between speed and accuracy.
2Speed
If bandwidth is increased to achieve faster communication speed, then signal transmission speed is improved, but the RC of the bus line becomes a limiting factor
Solution Approach 1:
The patent changes the key parameter of communication from using full-length serial IDs to using shortened local IDs. This parameter change reduces the data transmission volume and allows the system to operate effectively within the existing bus line RC constraints, achieving fast communication without requiring increased bandwidth that would be limited by the physical characteristics of the bus line.
3Measurement precision
If individual serial ID communication is used for each detonator, then identification accuracy is improved, but system productivity decreases
Solution Approach 1:
The patent merges multiple verification operations into a single broadcast communication event. By using local IDs that can be verified simultaneously across multiple detonators through a single broadcast message, the system achieves both accurate verification and high throughput. This merging eliminates the need for sequential individual communications while maintaining verification integrity.

Implementation Method 1
an acoustic transducer, such as a speaker, in the initiation device may be used to generate acoustic waves that propagate through the borehole fluid to an acoustic transducer, such as a microphone, in the electronic detonator
Implementation Method 2
an acoustic transducer, such as a microphone, in the electronic detonator receives the acoustic waves and decodes the data
