Remote Power Management via Server Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing PMBus power management protocol is limited by its dependency on an onboard system, making it difficult to control or expand power supply systems, and lacks remote monitoring and control capabilities, which can lead to inconvenience and potential system failures.
Innovation Solution
A remote power management apparatus and method that utilizes a remote server to control and monitor power supplies through an interface, allowing for remote control and monitoring via a managing unit with features like controllers, monitors, and abnormality processors, using interfaces such as Ethernet, USB, or USART, enabling dynamic control and expansion of power supplies without affecting powered devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If PMBus protocol is used for power management, then power supply control is simplified and standardized, but the system becomes dependent on onboard systems and lacks remote control capability
Solution Approach 1:
The patent introduces a remote server as an intermediary between the user and the power supply system. The remote server communicates with the power supply through standard interfaces (I2C, SMBus, PMBus), enabling remote control without requiring direct connection to the power supply. This mediator approach allows the system to maintain PMBus simplicity while adding remote accessibility.
2Extent of automation
If PMBus protocol is used for power management, then digital control is achieved, but the system cannot be controlled by alternative ways when onboard system fails
Solution Approach 1:
The remote server acts as an alternative control path that can take over when the onboard system fails. It communicates with the power supply through standard digital interfaces, providing backup control capability that maintains system operation even when the primary onboard control system is unavailable.
Solution Approach 2:
The system allows dynamic changes to control parameters and operational modes through the remote server. It can modify power supply settings, monitoring thresholds, and control strategies adaptively, enabling the system to respond to different operational conditions and failure scenarios by changing operational parameters.
3Ease of manufacture
If PMBus protocol is used for power management, then power development becomes simpler, but the system becomes inconvenient to expand and change
Solution Approach 1:
The remote server provides a universal control interface that can manage multiple power supplies and different power management scenarios through standard protocols. This multi-functional approach allows the system to be expanded to include additional power supplies or modified for different applications without requiring proprietary or custom control mechanisms.
