Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in plants or factories, which conform to different wireless standards like ISA100 and WirelessHART, cannot communicate with each other, leading to high initial costs, reduced convenience and ease of maintenance, and limited expandability due to the need for separate systems and tools.
Innovation Solution
A communication device and system that includes an identification control unit in the data-link layer to identify data and route it between different wireless networks, enabling communication between systems conforming to ISA100 and WirelessHART standards, thereby reducing costs and improving maintenance and expandability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate communication systems conforming to different wireless standards (ISA100, WirelessHART) are implemented, then each system can operate independently with standardized protocols, but the initial cost increases and multiple devices must be provided
Solution Approach 1:
The patent combines multiple wireless communication standards (ISA100 and WirelessHART) into a single gateway device that supports both protocols simultaneously. This merging approach allows the gateway to communicate with devices from both standards through a unified interface, reducing the total number of devices needed while maintaining the reliability of independent system operation.
Solution Approach 2:
The gateway device is designed with multi-functionality to support multiple wireless communication standards. By incorporating both ISA100 and WirelessHART protocol capabilities within a single device, the system achieves universality, allowing one device to perform the functions previously requiring separate dedicated devices for each standard.
2Reliability
If separate communication systems conforming to different wireless standards are implemented, then each system maintains its own protocol standards, but the cost of maintenance and management increases due to requiring different tools for each system
Solution Approach 1:
The gateway device provides universal support for multiple wireless communication standards, allowing a single maintenance tool to manage both ISA100 and WirelessHART networks through the unified gateway interface. This eliminates the need for separate maintenance tools for each standard, reducing maintenance costs while preserving protocol standard compliance.
Solution Approach 2:
The gateway acts as an intermediary between devices using different wireless standards and the control system. It translates and forwards messages between ISA100 and WirelessHART networks, allowing maintenance personnel to access and manage both networks through a single standardized interface, thereby simplifying maintenance operations.
3Reliability
If separate communication systems conforming to different wireless standards are implemented, then each system operates independently, but expandability is reduced
Solution Approach 1:
The gateway device provides a unified access point that supports multiple wireless communication standards, enabling the system to expand by adding devices from different standards without requiring separate gateway devices. This multi-functional gateway enhances expandability while maintaining the independence and reliability of each protocol's operation.
