Dual-Mode Telemetry Communication for Power and Bandwidth Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telemetry devices in industrial plants, which are often powered by solar and/or battery, face challenges in conserving power due to the need for efficient communication methods that balance low power consumption with data transmission requirements.
Innovation Solution
Implementing a dual communication system comprising a primary low power/low bandwidth method and a secondary high power/high bandwidth method, allowing devices to switch between these based on communication needs, thereby optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If low power communication methodology is used, then power consumption is reduced, but communication bandwidth is limited
Solution Approach 1:
The system dynamically switches between primary low power communication methodology and secondary high power communication methodology based on operational needs. The outstation and telemetry communication device can adaptively select which communication system to use, making the power consumption and bandwidth characteristics variable rather than fixed, thus resolving the contradiction between low power consumption and sufficient bandwidth.
2Productivity
If high power communication methodology is used, then communication bandwidth is increased, but power consumption increases
Solution Approach 1:
The communication system is segmented into two distinct parts: a primary communication system using low power methodology and a secondary communication system using high power methodology. Each segment serves specific purposes - the primary for routine low-bandwidth operations and the secondary for high-bandwidth requirements - allowing the system to optimize power consumption by using only the necessary segment for each communication task.
3Adaptability or versatility
If dual communication system is implemented, then communication flexibility is improved, but device complexity increases
Solution Approach 1:
Both the outstation and telemetry communication device are designed with multi-functionality, capable of operating with either the primary low power communication system or the secondary high power communication system. This universal design allows a single device to perform multiple communication functions across different power and bandwidth requirements, achieving flexibility without proportionally increasing complexity.

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.
