Electronic Shelf Label Frame Listening for Fast Response and Low Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic shelf labels face a dilemma in balancing high real-time performance and low power consumption, as increasing the frame-listening cycle to conserve power leads to delayed responses.
Innovation Solution
A method is introduced to configure a fixed frame-listening cycle based on predicted service types, switching between fast and low power consumption cycles to meet real-time demands, with dynamic adjustments via modification commands and external triggers.

1Use of energy by moving object
If the frame-listening cycle is increased to save power, then power consumption is reduced, but the response time increases and real-time performance deteriorates
Solution Approach 1:
The patent applies dynamics by making the frame-listening cycle adjustable rather than fixed. The electronic shelf label can dynamically switch between a first frame-listening cycle (for power saving) and a second frame-listening cycle (for fast response) based on service requirements. This is achieved through receiving adjustment instructions from the server that specify different frame-listening cycles for different services, allowing the system to optimize between power consumption and response time in real-time.
Solution Approach 2:
The patent changes the parameter of frame-listening cycle based on service types. The server identifies service types (e.g., power-saving services vs. fast-response services) and sends adjustment instructions to set appropriate frame-listening cycle values. This parameter change allows the electronic shelf label to adapt its listening behavior to match service requirements, reducing power consumption for non-urgent services while ensuring fast response for time-sensitive services.
2Device complexity
If a fixed frame-listening cycle is used, then device complexity is reduced, but the system cannot simultaneously satisfy high real-time performance and low power consumption
Solution Approach 1:
The patent implements self-service by allowing the electronic shelf label to automatically adjust its frame-listening cycle based on service requirements without requiring complex manual configuration. The server sends adjustment instructions that the label executes autonomously, and the label can also autonomously switch between different frame-listening cycles based on the type of service being performed. This reduces the burden on the system while maintaining high adaptability.
Solution Approach 2:
The patent segments services into different categories (e.g., power-saving services and fast-response services) and assigns different frame-listening cycles to different service segments. This segmentation allows the system to manage complexity by handling different service types with appropriate parameters, achieving both low complexity in individual service handling and high versatility across multiple service types.

AI summary
The present application provides a method for adjusting a frame-listening cycle, a shelf label system, a computer device, and a storage medium. The method includes: configuring, by a server, a fixed frame-listening cycle of an electronic shelf label according to a time period; and sending, by the server, a second frame-listening cycle modification command through a base station when the server is to issue the fast response service during the low power consumption time period, so that the electronic shelf label modifies the current frame-listening cycle to a fast frame-listening cycle according to the second frame-listening cycle modification command. According to the present application, the fixed frame-listening cycle of the electronic shelf label is configured by predicting an issuance time period of each service, so that the electronic shelf label can not only respond to the fast response service in real time, but also keep the low power consumption of a long frame-listening cycle, thereby simultaneously satisfying the requirements of high real-time performance and low power consumption of the electronic shelf label.
