Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate protocol conversion devices are used for different communication protocols, then data transmission compatibility is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple protocol conversion devices into a single gateway device that can handle multiple communication protocols simultaneously. This gateway device integrates the functions of what would otherwise be separate devices, reducing system complexity while maintaining compatibility across different protocols through unified management and processing.
Solution Approach 2:
The gateway device is designed with multi-functionality to support multiple communication protocols (such as MQTT, CoAP, HTTP) within a single device. This universal approach allows the same device to perform protocol conversion for different types of sensors and communication standards, eliminating the need for dedicated protocol conversion devices for each protocol type.
2Adaptability or versatility
If data is transmitted through multiple intermediate devices, then protocol compatibility is improved, but data transmission time increases
Solution Approach 1:
The patent extracts the protocol conversion function from multiple intermediate devices and consolidates it into a single gateway device positioned at the network edge. This extraction and consolidation reduces the number of data transmission hops, allowing data to be converted to the target protocol in one location rather than passing through multiple intermediate conversion points, thereby reducing transmission time.
Solution Approach 2:
The gateway device serves as an optimized intermediary that directly connects sensor networks to the platform. By positioning this single intermediary at the network edge closest to the sensors, the system minimizes the number of intermediate steps in data transmission while maintaining protocol compatibility, thus reducing overall transmission time compared to multiple distributed intermediaries.
3Ease of operation
If a centralized platform processes all data, then data management control is improved, but processing load on the platform increases
Solution Approach 1:
The patent segments the data processing function by introducing edge computing capabilities at the gateway device. Instead of all data processing occurring at the centralized platform, the gateway performs initial data filtering, preprocessing, and local analysis. This segmentation offloads significant processing tasks from the centralized platform, reducing its processing load while maintaining centralized management control over the overall system architecture and data flow.

AI summary
Methods, industrial Internet of Things systems, and storage mediums for controlling production line detection data are provided. The industrial Internet of Things system includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform. The service platform and the management platform use a centralized arrangement. The management platform sends a data request and receives production line detection data. The sensor network platform uses an arrangement of a front sub-platform, the sensor network platform includes a total platform and a plurality of sub-platforms, the sub-platforms are child node gateway devices in different communication networks, and the total platform is a total node gateway device aggregated by all the communication networks. The sensor network platform retrieves the production line detection data from the total node gateway device or the child node gateway devices based on a data request sent by the management platform.
