Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial facilities face challenges in efficiently monitoring machine parameters due to limited bandwidth and battery life of battery-powered field units, leading to data transmission delays, errors, frequent battery replacements, and safety concerns, as conventional methods transmit entire waveforms or fixed a priori bands that often include insignificant data.
Innovation Solution
The system analyzes machine parameters at the field unit based on analysis parameters received from a base station, identifying relevant data and generating a representation of the parameter, which reduces the amount of data transmitted, specifically by determining frequency bands of interest related to operation speed, thereby conserving power and extending battery life.

Engineering Contradiction Analysis
1Loss of information
If the entire waveform or large amounts of data are transmitted from the field unit to the base unit, then the information completeness is improved, but the data transmission bandwidth and battery life are worsened
Solution Approach 1:
The patent extracts only the relevant features and parameters from the complete waveform data at the field unit before transmission. Instead of transmitting the entire waveform, the system identifies and transmits only the essential characteristics needed for monitoring, thereby reducing data volume and energy consumption while maintaining information completeness for decision-making purposes.
Solution Approach 2:
The patent transforms the raw waveform data into different parameter representations (such as extracted features, statistics, or simplified metrics) that convey the same monitoring information with significantly reduced data volume. This parameter transformation allows the system to maintain information completeness while dramatically reducing the energy required for transmission.
2Loss of information
If the entire waveform or large amounts of data are transmitted from the field unit to the base unit, then the information completeness is improved, but the data transmission bandwidth is worsened
Solution Approach 1:
The system extracts only the essential features from the complete waveform data at the field unit. By identifying and transmitting only the relevant characteristics needed for effective monitoring, the patent reduces the data transmission volume while maintaining information completeness for operational decision-making.
Solution Approach 2:
The patent transforms raw waveform data into condensed parameter representations that preserve the essential monitoring information. This transformation reduces the quantity of data transmitted over the network while ensuring that all necessary information for monitoring and decision-making remains intact.
3Quantity of substance
If fixed a priori bands of the signal are transmitted, then the data transmission volume is reduced, but the relevant bands of interest are not encompassed
Solution Approach 1:
The patent implements dynamic adaptation of the signal bands transmitted based on actual monitoring needs and conditions. Instead of using fixed a priori bands, the system adjusts which frequency bands and signal characteristics are extracted and transmitted in real-time, ensuring that the most relevant information is always captured while maintaining reduced data transmission volume.
Solution Approach 2:
The system uses feedback mechanisms to determine which signal bands and features are most relevant for current monitoring conditions. Based on this feedback, the field unit dynamically selects and transmits only the pertinent signal characteristics, ensuring both reduced data volume and high relevance of the transmitted information.

AI summary
A sensor sampling system comprises a field unit to receive at least one analysis parameter from a base station and a signal representing a machine parameter monitored by a machine sensor. The field unit analyzes the signal based on the at least one machine parameter to generate a representation of the machine parameter, and wirelessly transmits the representation of the machine parameter for reception by the base station.
