Daisy Chain Power Control via Wireless Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional daisy chain storage systems require a dedicated power supply control device, leading to increased costs, power consumption, and system enlargement, as they lack the capability to control power supply without external devices.
Innovation Solution
A daisy chain connection system where the first information equipment controls multiple second information equipment via a wireless communication link, allowing for power supply control without the need for a dedicated power supply control device by using a combination of wired and wireless communication circuits for power management.

Engineering Contradiction Analysis
1Extent of automation
If a dedicated power supply control device is added to enable power supply control in daisy chain-connected enclosures, then power supply control capability is improved, but device complexity and cost increase
Solution Approach 1:
The master enclosure's control unit is made multi-functional by enabling it to perform both data communication and power supply control functions. The control unit transmits both data signals and power supply control signals through the same communication interface to slave enclosures, eliminating the need for separate dedicated power supply control devices and reducing overall system complexity.
Solution Approach 2:
The invention merges the power supply control function with the existing data communication function in the master enclosure's control unit. By combining these functions into a single control unit and using a unified communication interface, the system avoids adding separate control devices while maintaining both data communication and power supply control capabilities.
2Extent of automation
If a dedicated power supply control device is added to control power supply to slave enclosures, then power supply control is improved, but power consumption increases
Solution Approach 1:
The control unit in the master enclosure performs multiple functions including both data processing and power supply control. By making the control unit multi-functional, the system eliminates the need for additional dedicated power supply control devices that would consume extra power, thereby reducing overall system power consumption while maintaining full power supply control capability.
3Extent of automation
If a dedicated power supply control device is added to enable power supply control, then power supply control capability is improved, but system size and cost increase
Solution Approach 1:
The invention combines the power supply control function with the existing control unit in the master enclosure, merging multiple functions into a single component. This approach reduces the quantity of system components by eliminating the need for separate dedicated power supply control devices, while still providing comprehensive power supply control to slave enclosures.
Solution Approach 2:
The control unit is designed to perform multiple functions including data communication, power supply control, and enclosure management. By making the control unit universal and multi-functional, the system reduces the total number of components needed, as the same control unit handles both data and power control tasks without requiring additional dedicated devices.

AI summary
A system having information equipment connected in a daisy chain, where power supply control of the daisy chain-connected information equipment is performed without having to add a dedicated power supply control device. In a daisy chain connection system, second information equipment comprise a control unit and a power supply unit, and a first information equipment and the control unit of the second information equipment include a communication circuit capable of wired communication, and the first information equipment and the power supply unit of the second information equipment include a wireless circuit capable of wireless communication. When turning OFF a power supply to any one of the second information equipment, the first information equipment requests the power supply unit to stop the power supply by using wireless communication, and the power supply unit performs control for stopping the power supply to the control unit according to the request.
