Title:
MULTI-SENSOR DATA FUSION-BASED SELF-POWERED TRANSMISSION LINE ONLINE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/252408
Kind Code:
A1
Abstract:
A multi-sensor data fusion-based self-powered transmission line online monitoring system, comprising a plurality of detection nodes, an optical communication receiving demodulation module, and a data processing module. Each detection node comprises a vibration energy collection module, a sensing module, and an optical communication modulation transmitting module. The detection nodes convert and collect energy by means of a triboelectric nanogenerator (TENG), use the sensing modules to collect various types of sensing data, and modulate and transmit same by means of the optical communication modulation transmitting modules, and the optical communication receiving demodulation module correspondingly receives and demodulates the sensing data, and transmits same to the data processing module for processing. The processing process comprises fusing sensing data of the same type by using the weighted least squares method, analyzing sensing data of different types by using a fuzzy comprehensive evaluation method, and finally obtaining a monitoring result. By means of two-layer analysis on data, the accuracy of the data collected by the sensor is improved, and the validity and reliability of data fusion output results are improved. The detection nodes have the features of having a small volume and a light weight, and being self-powered.
