Remote Testing System Power Control via Dual Receiver Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote testing of electronic devices often requires development boards to be continuously powered on, leading to unnecessary energy consumption and difficulties in performing hard resets due to geographical distance and network-based access.
Innovation Solution
A system comprising a test circuit, a first receiver unit for test commands, a power supply unit, and a second receiver unit for power commands, which allows for controlled power management and remote operation of the development board, enabling efficient power usage and remote hard resets through a network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If development boards are permanently left on to facilitate remote access from different time zones, then remote accessibility is improved, but power consumption increases unnecessarily
Solution Approach 1:
The system dynamically adjusts the power state of the development board based on operational needs. The board transitions between powered-on and powered-off states, allowing remote accessibility when needed while conserving energy when not in use. This is achieved through remote wake-up capability that allows the board to be activated on-demand rather than remaining continuously powered.
2Use of energy by stationary object
If development boards are turned off to save power, then power consumption is reduced, but hard resets become difficult to perform remotely
Solution Approach 1:
The system prepares for potential reset needs by implementing a wake-up mechanism that can be triggered remotely even when the board is in a low-power state. The wake-up capability is预先 established, allowing the board to be activated and reset remotely without requiring physical access, thus maintaining hard reset capability while enabling power savings.
3Productivity
If development boards remain powered on for remote testing, then testing availability is improved, but energy waste increases
Solution Approach 1:
The system implements periodic or on-demand power activation rather than continuous operation. The development board is powered on only when testing is required and can be remotely activated through the wake-up function. This periodic activation pattern maintains testing availability when needed while eliminating energy waste during idle periods.
