Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility systems face challenges with incomplete or delayed data transmission due to battery-powered sensors, leading to reduced opportunities for addressing conditions before they escalate, and network traffic congestion from numerous devices.
Innovation Solution
A telemetry device dynamically adjusts data package content and transmission intervals based on sensed data ranges, transmitting more data at shorter intervals as values approach alarm thresholds to provide timely data to the central utility controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If real time data transmission is minimized to extend battery life, then energy consumption is reduced, but data completeness and timeliness deteriorate
Solution Approach 1:
The system dynamically adjusts data transmission frequency and package size based on the current state of monitored parameters. When parameters are within normal ranges, transmission is minimized to conserve battery life. When parameters approach alarm thresholds, transmission frequency increases and data package size expands to ensure complete and timely information delivery, thus resolving the contradiction between energy conservation and data completeness
Solution Approach 2:
The system changes transmission parameters (frequency, data volume, packet size) based on the magnitude of sensed values relative to alarm thresholds. By adjusting these parameters dynamically according to the current operational state, the system optimizes the balance between energy consumption and information completeness, ensuring sufficient data is transmitted only when necessary
2Use of energy by moving object
If real time data transmission is minimized to optimize battery life, then energy consumption is reduced, but system responsiveness deteriorates
Solution Approach 1:
The transmission schedule is made dynamic rather than static. The system continuously monitors parameter values and adjusts transmission timing accordingly, switching from periodic transmission to event-driven transmission when conditions warrant immediate attention, thus maintaining system responsiveness while optimizing energy usage during normal operation
Solution Approach 2:
The system performs preliminary data collection and prepares data packages in advance when parameters are stable, so that when alarm conditions occur, data can be transmitted immediately without delay. This preliminary preparation ensures rapid response time when needed while maintaining low transmission frequency during normal operation to conserve battery life
3Loss of time
If data transmission frequency is increased to provide timely data, then system responsiveness is improved, but network traffic increases
Solution Approach 1:
The system transmits only the necessary amount of data (partial action) based on the current state. When parameters are normal, minimal data is transmitted. When parameters approach alarm thresholds, more comprehensive data is transmitted (excessive action relative to normal operation but appropriate to the situation). This ensures timely detection of developing issues while avoiding unnecessary network traffic during stable operation
Solution Approach 2:
The system changes data transmission parameters (frequency, volume, detail level) based on the current operational state and proximity to alarm conditions. By adjusting these parameters dynamically, the system provides timely data when needed while minimizing network traffic during normal operation, resolving the contradiction between responsiveness and network utilization
4Loss of information
If data package size is increased to provide more data values, then information completeness is improved, but transmission energy consumption increases
Solution Approach 1:
The system includes only the necessary data values in each transmission (partial action). When parameters are within normal ranges, data packages contain minimal information. When parameters approach alarm thresholds, data packages expand to include more historical data and detailed values (excessive action relative to normal operation but appropriate to the situation). This ensures complete information is available when needed while minimizing transmission energy consumption during stable operation

AI summary
A telemetry device is configured to receive data from one or more sensing devices associated with a component of a utility system. The telemetry device processes the received data by determining a range associated with a value of the received data, and in response to determining the value of the received data is in a first range, generate a first data package having a second number of received data values and transmit the first data package at a first transmission interval. In response to determining that the value of the received data is in a second range, the telemetry device is configured to generate a second data package having a second number of received data values and transmit the second data package at a second transmission interval.
