Bulk Explosive Loading Controller With Independent HMI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bulk explosive loading systems often feature outdated and difficult-to-use user interfaces that are tied to the controller, making them expensive and hard to update or replace, which poses challenges in safely and efficiently managing explosive mixtures in mining and drilling operations.
Innovation Solution
A Human-Machine Interface (HMI) that is independent of the controller, allowing for real-time communication and reconfiguration without affecting the controller, providing a more robust and updatable interface for operators, enabling secure access and management of explosive mixture recipes and delivery processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user interface is tied to the controller, then the system structure is simple, but the interface becomes outdated and difficult to update or replace
Solution Approach 1:
The system is divided into two independent parts: the controller that manages explosive loading operations and the human-machine interface (HMI) that provides user interaction. This segmentation allows the HMI to be updated or replaced without modifying the controller, resolving the contradiction between interface adaptability and system complexity.
Solution Approach 2:
The HMI is extracted from the controller as a separate, independent component. This extraction enables the interface to be developed, updated, and replaced independently while the controller remains unchanged, achieving interface versatility without proportionally increasing overall system complexity.
2Ease of repair
If the user interface is tied to the controller, then the system is compact, but updates or replacements become expensive and difficult
Solution Approach 1:
By segmenting the HMI from the controller, the interface becomes a replaceable module that can be maintained and updated independently, significantly improving ease of repair while maintaining manageable system integration through standardized communication protocols.
3Ease of operation
If the user interface provides comprehensive control features, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The HMI is designed as a universal interface that can provide comprehensive control features for multiple functions and operations. By making the interface multi-functional and highly capable, it improves ease of operation while the independent architecture prevents this complexity from propagating to the controller, effectively decoupling interface complexity from system complexity.

AI summary
Controllers and methods of bulk explosive loading systems are disclosed. A controller of a bulk explosive loading system includes a communication interface configured to communicate with a human-machine interface (HMI). The HMI is configured to execute a software program configured to enable the HMI to receive user inputs from a user. The controller also includes control outputs to output control signals to electrically controllable components. The controller further includes sensor inputs configured to receive sensor signals from sensors configured to monitor the bulk explosive loading system. The controller also includes a processor configured to process recipe information received from the HMI, generate the control signals based on the recipe information to control the electrically controllable components to blend the mixture, process the sensor signals received during blending of the mixture, and transmit blending information to the HMI device. The blending information includes information regarding the blending of the mixture.
