Synchronized Network Battery Backup Sleep Schedule
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network devices with battery backup systems face challenges such as high costs, increased volume and weight due to large battery capacity, and limited battery life, which necessitate reducing power consumption during mains power failures to extend battery reserves.
Innovation Solution
Implementing a synchronized network with a coordinated sleep schedule that restricts data transmission to specific windows when mains power is unavailable, allowing devices to operate in low-power mode and conserve battery life, while transmitting data freely when mains power is restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to meet power needs during mains power failure, then battery backup duration is improved, but device volume and weight increase
Solution Approach 1:
The patent implements a synchronized sleep schedule where network devices alternate between active transmission windows and sleep periods. During sleep mode, devices significantly reduce power consumption, allowing smaller batteries to provide adequate backup duration without increasing device weight. This periodic operation pattern enables the system to extend effective battery life while avoiding the need for large, heavy battery capacities.
2Duration of action of moving object
If battery capacity is increased to meet power needs during mains power failure, then battery backup duration is improved, but device cost increases
Solution Approach 1:
By implementing synchronized sleep schedules with periodic active windows for data transmission, the system reduces average power consumption during battery operation. This allows the use of smaller, less expensive batteries that still provide adequate backup duration, thereby reducing device manufacturing cost while maintaining acceptable battery backup performance.
3Productivity
If data transmission is unrestricted during battery operation, then network performance is improved, but battery power consumption increases
Solution Approach 1:
The patent establishes synchronized sleep schedules where all network devices coordinate their active transmission windows and sleep periods. During battery operation, devices transmit data only during designated active windows and remain in low-power sleep mode otherwise. This periodic transmission pattern maintains essential network functionality while dramatically reducing battery power consumption compared to unrestricted continuous transmission.
4Use of energy by moving object
If synchronized sleep schedule is implemented during battery operation, then battery power consumption is reduced, but network performance decreases
Solution Approach 1:
The system dynamically adapts its operation mode based on power availability. When mains power is present, devices operate without sleep restrictions achieving full network performance. When battery operation begins, devices transition to synchronized sleep schedules that balance power consumption with network functionality. This dynamic adjustment allows the system to optimize between performance and power consumption according to current operating conditions.

AI summary
Devices, systems, and techniques for a synchronized network for battery backup are described herein. A network device can establish a synchronized sleep schedule with the network while in a mains-power mode of operation. The network device can transmit data in the mains-power mode without regard for a transmission window of the synchronized sleep schedule. The network device can detect an interruption of mains power to itself and transition to a low-power mode of operation. The network device can then transmit data in the low-power mode, restricting data transmission to the transmission window of the synchronized sleep schedule.
