Electronic Shelf Label Wake-Up via Composite Data Packet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic shelf label systems require sending multiple wake-up signals serially to wake up individual electronic shelf labels, resulting in inefficient batch wake-up operations due to the large number of labels and the need for prolonged overall wake-up time.
Innovation Solution
A method where a master terminal device receives an electronic shelf label wake-up instruction, determines the target feature information of all labels to be woken up, constructs a wake-up data packet, and sends it to all labels, allowing multiple electronic shelf labels to be woken up simultaneously by including their feature information, such as tag IDs or masks, in a single data packet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wake-up signals are sent to each electronic shelf label one by one, then each label can be reliably woken up, but the overall wake-up time becomes very long
Solution Approach 1:
The patent merges multiple individual wake-up signals into a single composite wake-up data packet that contains wake-up information for multiple electronic shelf labels simultaneously. This single packet is transmitted once to wake up all target labels at the same time, resolving the contradiction between reliable individual wake-up and long overall wake-up time.
Solution Approach 2:
The wake-up data packet is segmented to include multiple target identification values, each corresponding to a specific electronic shelf label. This segmentation allows the system to maintain individual label identification and wake-up reliability while transmitting all wake-up commands in a single consolidated packet, eliminating the need for sequential transmission.
2Ease of operation
If multiple wake-up signals are sent sequentially, then each signal can be processed individually, but the processing efficiency and throughput are reduced
Solution Approach 1:
The patent combines multiple individual wake-up operations into a single batch operation by creating a wake-up data packet that contains multiple target identification values. This allows the master terminal device to wake up multiple electronic shelf labels simultaneously through one transmission, dramatically improving batch processing efficiency while maintaining the ability to individually identify and address each label.
3Use of energy by stationary object
If the system wakes up all electronic shelf labels one by one, then power consumption can be minimized by keeping labels dormant, but the system responsiveness and update speed are slowed
Solution Approach 1:
The system prepares wake-up data packets in advance that contain pre-calculated target identification values for multiple electronic shelf labels. When a wake-up operation is needed, the pre-prepared packet can be immediately transmitted to multiple labels simultaneously, enabling fast system response while maintaining the energy-efficient dormant state of labels until needed.
