Frame Controller Power Cutoff for Multi-Slot Measurement Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional frame controllers struggle to support multiple-slot-width modules effectively, as they cannot simultaneously unpower multiple slots occupied by such modules, leading to potential damage from excessive current flow.
Innovation Solution
A measurement apparatus with a power supply manager that identifies and stops powering all slots connected to a module with an anomaly, using a power supply control table to ensure all relevant slots are unpowered simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional frame controllers unpower slots individually when an anomaly is detected, then the control logic is simple, but multiple-slot-width modules cannot be properly supported and excessive current may flow damaging internal circuits
Solution Approach 1:
The patent segments the power supply control by introducing a power supply control table that associates each module with its connected slots. When an anomaly is detected in one slot, the system identifies all slots connected to the same module through this table and unpowers them simultaneously. This segmentation approach allows complex multi-slot module management while maintaining simple individual slot control logic.
Solution Approach 2:
The power supply control table serves as an intermediary data structure between the anomaly detection mechanism and the power supply control logic. It stores the correspondence between modules and their connected slots, enabling the system to translate a single-slot anomaly into coordinated multi-slot power control without complex direct control logic.
2Adaptability or versatility
If the system supports multiple-slot-width modules by unpowering all connected slots simultaneously, then module support is improved, but the control mechanism becomes more complex
Solution Approach 1:
The power supply control table provides a universal solution that works for all module types regardless of their slot width. By storing module-to-slot mappings in a standardized format, the system can handle 1-slot, 2-slot, 3-slot, and other multi-slot modules uniformly through the same anomaly response mechanism, enhancing adaptability without requiring separate control logic for each module type.
Solution Approach 2:
The system performs preliminary action by pre-establishing the power supply control table that maps each module to its connected slots before anomalies occur. This advance preparation allows the anomaly response mechanism to quickly identify and unpower all relevant slots simultaneously without requiring complex real-time analysis, thus supporting multiple-slot-width modules efficiently.
3Reliability
If individual slot powering control is used, then the power control is simple, but modules spanning multiple slots cannot be properly protected from excessive current
Solution Approach 1:
The system uses feedback through the power supply control table to automatically determine which slots need to be unpowered based on the anomaly location. When an anomaly is detected in one slot, the feedback mechanism queries the table to identify all slots connected to the same module and unpowers them accordingly, providing automatic module-level protection without requiring manual intervention or complex control operations.

AI summary
It would be helpful to enable a frame controller to support multiple- slot-width modules. A measurement apparatus includes a plurality of slots to which one or more modules are connectable, a power supply manager configured to control powering the modules connected to the plurality of slots, and a display configured to display measurement signals acquired by the modules. The power supply manager is configured to, when an anomaly is detected at any slot of the plurality of slots, identify, as one or more target slots, all one or more slots to which a module connected to the slot with the detected anomaly is connected, and stop powering the identified target slots.
