State Monitoring Device Dual Communication Line Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing state monitoring systems are ineffective in areas with poor communication environments, as they rely on internet connectivity and cannot transmit monitoring information to maintenance workers when communication infrastructure is lacking.
Innovation Solution
A state monitoring device that uses a primary communication line for normal data transmission and switches to a wireless communication line via a mobile object when the primary line is unavailable, ensuring continuous data transmission to a server device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a first communication line is used to transmit operating information to a server device, then communication reliability is improved in areas with good infrastructure, but the system becomes inapplicable in remote areas with poor communication environments
Solution Approach 1:
The system dynamically switches between first communication line (wired/infrastructure-based) and second communication line (wireless/mobile-based) depending on availability. The state monitoring device detects communication line status and automatically selects the appropriate transmission path, making the system adaptable to both infrastructure-rich and remote areas.
Solution Approach 2:
A mobile object (such as a smartphone or mobile device) acts as an intermediary carrier to transmit operating information from the state monitoring device to the server device when the first communication line is unavailable. This intermediary enables communication in remote areas without fixed infrastructure.
2Adaptability or versatility
If a wireless communication via mobile object is used as backup, then adaptability to remote areas is improved, but device complexity increases
Solution Approach 1:
The state monitoring device incorporates multiple communication capabilities (first communication line interface and second communication line interface) within a single unit. This multi-functionality allows the device to operate in diverse environments without requiring separate systems, managing complexity through integration rather than multiplication of components.
Solution Approach 2:
The system automatically detects communication line status and selects the appropriate transmission path without external intervention. The mobile object autonomously functions as a communication carrier when needed, reducing the need for complex manual configuration or external control systems.

AI summary
The present invention provides a state monitoring device which make it possible to certainly deliver, to the maintenance staff side, state monitoring information of an apparatus to be monitored which is disposed in a distant place with a bad communication environment. A state monitoring device 300 is provided with a communication unit 301 which performs communication using a first communication line for transmitting operating information of an apparatus to be monitored to a server device, and a second communication line for transmitting the operating information to the server device via wireless communication provided by a mobile object if the first communication line is not communicable.
