Dual Telemetry Communication Switching for Power-Constrained Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telemetry devices in industrial plants, particularly remote devices, face challenges in conserving power due to their reliance on solar and/or battery power, necessitating efficient communication methods to maintain normal operations.
Innovation Solution
Implementing a dual communication system comprising a primary low power/low bandwidth method and a secondary high power/high bandwidth method, with the primary system being the default and the secondary system activated only when necessary, to optimize power conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high power communication methodology is used, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The communication system dynamically switches between low power and high power communication methodologies based on operational requirements. The system activates high power mode only when necessary for reliable data transmission, and uses low power mode during normal operations, making the power consumption adaptive rather than static.
Solution Approach 2:
The system changes communication parameters (power level, bandwidth) based on operational needs. By adjusting these parameters dynamically, the system optimizes the balance between transmission reliability and power consumption, avoiding continuous high power usage while ensuring reliability when required.
2Use of energy by moving object
If low power communication methodology is used, then power consumption is reduced, but data transmission bandwidth is limited
Solution Approach 1:
The system dynamically adjusts communication bandwidth based on operational requirements. During normal operations, low bandwidth mode conserves power. When high data transmission capacity is needed, the system switches to high bandwidth mode, making the productivity adaptive to actual needs rather than fixed.
3Adaptability or versatility
If dual communication system is implemented, then communication flexibility is improved, but device complexity increases
Solution Approach 1:
The communication system is segmented into distinct low power and high power subsystems, each optimized for specific operational scenarios. This segmentation allows independent control and optimization of each communication mode, managing complexity through modular architecture rather than a monolithic system.

AI summary
A telemetry communication system is configured for conserving power of telemetry devices of an industrial plant. The telemetry communication system comprises an external plant device and at least one of a telemetry communication device and an outstation. The telemetry communication device and outstation are configured to activate a primary communication system and a secondary communication system. The primary communication system is configured for executing a primary communication method comprising a low power communication methodology and a low bandwidth communication methodology for communicating with the external plant device. The secondary communication system is configured for executing a secondary communication method comprising a high power communication methodology and a high bandwidth communication methodology for communicating with the external plant device. Each of the telemetry communication device and outstation are configured to determine whether to use the primary or secondary communication system for communicating with the external plant device based on an event.
