Naval Power Monitoring Across HM&E and Weapon Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical power monitoring techniques fail to effectively observe and manage power consumption by individual weapon systems on naval ships due to cross-domain issues between unclassified Hull, Mechanical, and Electrical (HM&E) systems and classified weapon systems, lacking a holistic method to monitor both simultaneously.
Innovation Solution
The Power and Energy Requirement Systems to Evaluate Utility and Supply (PERSEUS) system, which uses sensors to monitor electrical consumption, compares data against lookup tables, and adjusts power usage to maintain system power below established thresholds, integrating with both HM&E and weapon systems for comprehensive power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electrical power monitoring techniques are used to monitor HM&E systems, then generator and electrical bus health can be monitored, but power consumption by individual weapon systems cannot be observed
Solution Approach 1:
The monitoring system is segmented into two independent parts: HM&E system monitoring (unclassified) and weapon system monitoring (classified). Each part operates independently with its own sensors and processing, eliminating the need for complex cross-domain communication while enabling precise power consumption observation at both levels.
Solution Approach 2:
A power management system acts as an intermediary that receives power consumption data from both HM&E and weapon systems through separate unclassified interfaces. This intermediary consolidates information from both domains without requiring direct communication between classified and unclassified systems, enabling comprehensive power monitoring while maintaining security boundaries.
2Adaptability or versatility
If HM&E systems and weapon systems communicate directly, then integrated power management is achieved, but cross-domain security issues arise
Solution Approach 1:
The power management system serves as an unclassified intermediary that receives power consumption information from both HM&E systems and weapon systems through separate interfaces. It performs integrated power management functions without requiring direct classified-unclassified communication, thus achieving adaptability while maintaining security reliability.
Solution Approach 2:
The system creates separate copies of power consumption data from HM&E and weapon systems, processes them independently through unclassified interfaces, and integrates the results at the power management level. This copying approach enables integrated management while avoiding direct cross-domain communication and its associated security risks.
3Power
If power consumption is increased for weapon systems, then combat effectiveness is improved, but system power threshold may be exceeded
Solution Approach 1:
The power management system continuously monitors real-time power consumption from both HM&E and weapon systems, compares it against available power thresholds, and provides feedback control. When power consumption approaches thresholds, the system can adjust or prioritize loads to prevent violations, enabling high power delivery to weapons when available while maintaining system-wide power constraints.
Solution Approach 2:
The system dynamically adjusts power allocation based on real-time conditions, weapon priority, and available power margins. Power consumption levels are not fixed but adapt continuously to operational needs and power availability, allowing maximum weapon power when possible while dynamically preventing threshold violations through real-time control.
