Mine Machine Remote Operation Zone Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mining machine operation systems fail to allow safe operation near personnel by only disabling the machine upon detecting their presence, rather than enabling controlled operation that avoids interference with individuals in specific zones.
Innovation Solution
A system comprising emitters, transmitters, and controllers that define and manage operational zones around mining machines, allowing controlled operation by preventing machine movements into zones where personnel are detected, while enabling operation in other zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the machine operation is disabled upon detecting the presence of an individual, then safety is improved, but productivity deteriorates
Solution Approach 1:
The system divides the workspace into multiple zones (first zone, second zone, third zone) with different safety requirements. The controller selectively disables machine operations only when an individual is detected in specific zones (first or second zone), while allowing operation when individuals are in the third zone. This localized approach maintains safety in critical areas while preserving productivity in safe areas.
2Reliability
If the machine operation is completely disabled when an individual is detected, then safety is improved, but device complexity increases
Solution Approach 1:
The detection system is segmented into multiple independent emitters (first emitter, second emitter, third emitter), each responsible for detecting presence in a specific zone. The controller receives signals from these separate emitters and applies different control logic based on which zone contains an individual. This segmentation simplifies the control logic compared to a single complex detection system, as each emitter only needs to detect its own zone independently.
3Productivity
If zone-based selective operation control is implemented, then productivity is improved, but measurement precision requirements increase
Solution Approach 1:
The workspace is divided into distinct, non-overlapping zones (first zone, second zone, third zone) with clear spatial boundaries. Each emitter is assigned to detect a specific zone, and the controller uses simple presence/absence logic for each zone rather than complex continuous positioning. This segmentation approach reduces measurement precision requirements compared to systems that would need to continuously and precisely track exact operator positions within a single large workspace.

AI summary
A system for remotely operating a machine, such as a mine vehicle, includes at least one first emitter for emitting a first signal corresponding to a first zone adjacent to the machine. A transmitter is provided for receiving the first signal emitted by the emitter, the transmitter being adapted for issuing commands for controlling the machine and also indicating the presence of the transmitter in the first zone. A controller is also provided for controlling the machine based on the control signals from the transmitter based on the presence of the transmitter in the first zone.
