Single Live Line Switch Sleep Mode Wake-Up Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single live line switches that incorporate remote control functionality require a wireless module, leading to unnecessary power consumption, especially when controlling loads like lamps, as the operating current of the wireless module continuously powers the load.
Innovation Solution
An intelligent switch system with a sleep mode and wake-up mode, where the wireless communication unit is powered by an energy storage unit during wake-up, reducing power consumption by using a wake-up signal with a specific central frequency to only activate the switch corresponding to the intended load, and entering sleep mode after state changes or queries are processed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless module is integrated into a single live line switch to enable remote control, then remote control functionality is achieved, but power consumption increases due to continuous operating current
Solution Approach 1:
The wireless communication unit operates periodically rather than continuously. It enters sleep mode to conserve energy and only activates when a wake-up signal is received, thus achieving remote control functionality while minimizing power consumption.
Solution Approach 2:
The system dynamically switches between sleep mode and active communication mode based on whether a wake-up signal is received. This dynamic operation allows the wireless module to be versatile when needed while consuming minimal power during normal operation.
2Speed
If the wireless communication unit remains active for remote control operations, then control responsiveness is improved, but power consumption increases causing continuous load operation
Solution Approach 1:
The system prepares for remote control operations by entering a low-power sleep state and only activates the wireless communication unit when a wake-up signal is detected. This preliminary preparation maintains responsiveness when control is needed while avoiding continuous power consumption.
Solution Approach 2:
The system changes its operational parameters by switching between sleep mode (low power, no communication) and active mode (higher power, responsive communication). This parameter change allows the system to maintain control responsiveness when needed while minimizing energy loss during normal operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach minimizes power consumption by ensuring the wireless communication unit is only active when necessary, reducing the current flowing through the load and preventing continuous illumination or operation of loads like lamps, thereby enhancing energy efficiency.
Implementation Method 1
the first wake-up unit receives wake-up signal H with a specific central frequency from the power source network, and converts the wake-up signal H into a resonant voltage signal X

AI summary
An intelligent switch system with reduced power consumption includes a wireless gateway, single live line intelligent switches, and one load per single live line intelligent switch. The wireless gateway generates wake-up signal, couples the wake-up signal to the alternating current power source network, and sends a control signal to all the intelligent switches. Each switch includes first wireless communication unit with sleep mode and wake-up mode, first wake-up unit, first controller, and switch unit. Every first wireless communication unit in wake-up mode receives the control signal. Every first wake-up unit receives and the wake-up signal to wake-up the first wireless communication unit if the control signal is tailored for that switch. The first controller analyzes the control signal and outputs a switch signal, the switch unit changes the on or off state of the load accordingly. When the switch unit is turned off, the current flowing is less than 50 uA.
