Beschreibung
Zusammenfassung:	A multi-sensor data fusion-based self-powered online monitoring system for a transmission line includes a plurality of detection nodes, an optical communication receiving and demodulation module, and a data processing module. The detection nodes each include a vibration energy harvesting module, a sensing module, and an optical communication modulation and transmitting module. The detection node uses a triboelectric nanogenerator (TENG) to convert and harvest energy, uses the sensing module to acquire a plurality of types of sensing data, and uses the optical communication modulation and transmitting module to modulate and transmit the sensing data. The optical communication receiving and demodulation module correspondingly receives and demodulates the sensing data, and transmits the sensing data to the data processing module for processing. The processing includes using a weighted least square method to fuse homogeneous sensing data and using a fuzzy comprehensive evaluation method to analyze heterogeneous sensing data.
