Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent manufacturing systems face communication challenges due to non-uniform interface standards, preventing seamless data exchange between systems.
Innovation Solution
A production control system is developed with a terminal server and manufacturing execution server that utilize multiple communications protocols to transmit control messages, allowing invocation of application modules and connecting through relay and database servers to establish a standardized interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication protocols are used to ensure compatibility between different intelligent manufacturing systems, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a gateway server as an intermediary component that supports multiple communication protocols (MQTT, HTTP, TCP). This gateway acts as a mediator between terminal servers and the manufacturing execution server, translating messages between different protocols. This resolves the contradiction by centralizing protocol handling in the gateway, keeping the core system simple while maintaining communication reliability across diverse systems.
2Adaptability or versatility
If a standardized interface is implemented to enable seamless communication, then adaptability is improved, but implementation complexity increases
Solution Approach 1:
The gateway server is designed with universal multi-functionality, supporting multiple communication protocols (MQTT, HTTP, TCP) and message formats within a single platform. This allows the system to adapt to different intelligent manufacturing systems without requiring separate interface implementations for each protocol, thereby improving adaptability while managing implementation complexity through consolidation.
3Speed
If control messages are transmitted frequently to ensure real-time monitoring, then response speed is improved, but communication overhead increases
Solution Approach 1:
The system implements periodic message transmission with configurable intervals. The terminal server can send control messages at optimized frequencies based on the specific monitoring requirements of different devices and processes. This periodic action ensures real-time monitoring capabilities while allowing communication overhead to be managed through intelligent frequency control, preventing excessive message transmission.
Data Source
AI summary
A production control system includes a terminal server and a manufacturing execution server. The terminal server is configured to transmit a control message. The manufacturing execution server is configured to receive the control message through a first communications protocol and a second communications protocol and to execute a first application module and a second application module according to the control message. The terminal server judges whether a quantity of the control message is greater than a predetermined value; if the quantity of the control message is judged to be greater than the predetermined value, then the terminal server transmits the control message through the first communications protocol; and if the quantity of the control message is judged to be less than or equal to the predetermined value, then the terminal server transmits the control message through the second communications protocol.
