Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless blasting systems face challenges in selectively controlling and firing wireless detonators in predetermined groups without physical connections, which complicates the setup and execution of blasting operations in mining.
Innovation Solution
A method involving wireless command signals with a group identification component that allows each wireless initiation device or booster to determine whether it belongs to a predetermined group, enabling selective execution of operations based on the signal, thereby allowing for the controlled actuation of explosive charges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless blasting systems are used to avoid physical connections between detonators, then safety and ease of setup are improved, but the ability to selectively control and fire detonators in predetermined groups becomes difficult to achieve
Solution Approach 1:
The patent segments wireless initiation devices into predetermined groups using group identification components. Each device receives a command signal that includes group identification data, allowing selective activation of specific groups. This segmentation enables safe wireless blasting while maintaining the ability to control detonators in predetermined groups for staged blasting operations.
2Device complexity
If wireless command signals are transmitted to all wireless initiation devices, then communication simplicity is improved, but the complexity of determining which devices should execute the operation increases
Solution Approach 1:
The patent introduces group identification components as intermediaries between the command signal and the wireless initiation devices. Each device contains a group identification component that compares the received signal's group identification data with its own stored identification. This intermediary mechanism enables simple universal signal transmission while providing accurate device selection through comparison and determination logic within each device.
