Two-Dimensional Addressing Map for 2.4G Label Batch Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current addressing methods for 2.4G electronic labels are limited by the cache of Bluetooth chips, restricting the ability to update labels in large batches, making them unsuitable for large-scale applications such as large supermarkets and warehouses.
Innovation Solution
A two-dimensional addressing method based on a 2.4G private protocol is introduced, where a server establishes a two-dimensional addressing map using MAC addresses, and a base station broadcasts updated information to labels, allowing for efficient updating of a few or many labels as needed, with labels automatically connecting to receive and apply updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional Bluetooth or 2.4G addressing methods are used, then the system is simple to implement, but the number of labels that can be updated at once is limited by cache size
Solution Approach 1:
The patent divides the addressing mechanism into two parts: a simple one-dimensional MAC address for basic identification and a new two-dimensional addressing map (row, column) for batch selection. This segmentation allows the system to maintain simplicity for individual label communication while enabling complex batch operations through the coordinated use of both addressing methods.
Solution Approach 2:
The patent transitions from one-dimensional MAC address addressing to two-dimensional (row, column) addressing in the addressing map. This dimensional change enables the system to select and update multiple labels simultaneously by specifying row and column ranges, thereby increasing batch update capacity without requiring fundamentally new communication protocols.
2Adaptability or versatility
If the addressing method is extended to support large-scale labels, then the adaptability to complex scenarios improves, but the cache resource consumption increases
Solution Approach 1:
The patent applies partial action by allowing the system to select and update only the necessary portion of labels based on the (row, column) addressing map, rather than requiring cache resources for all possible labels. The addressing map acts as an index that points to specific label groups, enabling the system to handle large-scale scenarios by accessing only the required data portions from cache.
Solution Approach 2:
The two-dimensional addressing map serves as an intermediary between the cache system and the label database. It translates high-level batch selection requirements into specific cache-accessible addresses, allowing the system to navigate large label datasets efficiently without requiring the entire dataset to reside in cache simultaneously.
3Productivity
If batch updating of labels is enabled, then the productivity increases, but the communication overhead and protocol complexity increase
Solution Approach 1:
The patent implements preliminary action by pre-establishing the two-dimensional addressing map structure and pre-organizing label data into the corresponding (row, column) grid. This preparation allows the system to perform efficient batch updates by simply specifying the target row and column ranges, avoiding the need for complex real-time calculations and reducing protocol complexity during actual update operations.

AI summary
The present invention discloses a two-dimensional addressing method for labels based on 2.4G private protocol, including: establishing, by a server, a two-dimensional addressing map based on MAC addresses of the labels in a system, and sending, through a base station AP, respective two-dimensional addresses to each of the labels for storage; accessing a database by the server, and distributing array map information and label data for updating to the base station AP, so that the base station AP sends the updated two-dimensional addressing map and the label data for updating to the label through broadcasting a signal by 2.4G; after receiving the broadcasted signal from the base station AP, automatically indexing, by the label, the array map information of the label and sending connection request information to the base station AP; and querying, by the base station AP, the MAC address of the label corresponding to the two-dimensional addressing map, connecting the label, and distributing the label data for updating to the label, so that the label performs a corresponding update action. According to the present invention, a few or a large number of electronic labels may be called based on requirements each time, thereby satisfying control requirements of the electronic label in a complex scenario.
