Edge Computing Schema Addressing for IoT Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The industrial Internet of Things faces high network bandwidth consumption and costs due to the large storage space occupied by schema in data format normalization, leading to inefficient data transmission in the industrial Internet of Things.
Innovation Solution
A data transmission system where the edge computing device requests a transmission address from the cloud server for a target schema, allowing it to receive only data values from the gateway, which then generates target data conforming to the schema, eliminating the need for repeated transmission of schema labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the gateway serializes data into specific formats (JSON, XML) and embeds the data in the schema for transmission, then the data format normalization is achieved, but the storage space occupied by the schema becomes higher than that occupied by the data, causing large network bandwidth consumption and high data transmission costs
Solution Approach 1:
The patent segments the schema into two parts: schema information (labels, data types, constraints) is stored in the cloud server's schema database, while only data values are transmitted from the gateway to the edge computing device. This segmentation eliminates redundant schema transmission and reduces network bandwidth consumption significantly.
Solution Approach 2:
The cloud server performs preliminary action by storing the schema information in advance in its schema database before data transmission occurs. When the edge computing device needs data, it requests the transmission address from the cloud server, and the gateway transmits only the data values according to the pre-stored schema, avoiding repeated schema transmission.
2Stability of the object's composition
If the gateway transmits complete normalized data including schema and data values, then the data format integrity is maintained, but the transmission volume increases unnecessarily due to repeated schema labels
Solution Approach 1:
The patent extracts the schema information from the transmitted data package and places it in the cloud server's schema database. Only the essential data values are transmitted from the gateway to the edge computing device. The edge computing device reconstructs the complete normalized data by combining received data values with schema information from the cloud server, maintaining data format integrity while minimizing transmission volume.
Solution Approach 2:
The cloud server's schema database serves multiple functions: it stores schema information for multiple data types, provides schema references to multiple edge computing devices, and enables multiple gateways to transmit data using the same schema definitions. This multi-functionality eliminates redundant schema storage and transmission across the entire industrial IoT system.
Data Source
AI summary
A data transmission system and a data transmission method are disclosed. The data transmission system includes a cloud server, an edge computing device, and a gateway. The cloud server includes a schema database which stores a transmission address corresponding to a target schema. The edge computing device transmits a data receiving request message related to the target schema to the cloud server. The cloud server transmits the transmission address to the edge computing device after receiving the data receiving request message. After receiving the transmission address, the edge computing device receives at least one data value corresponding to at least one label of the target schema from the gateway according to the transmission address, and generates a target data corresponding to the target schema according to the at least one label and the at least one data value.
