Abstract

The invention discloses a self-powered transmission line on-line monitoring system based on multi-sensor data fusion, wherein the system comprises a plurality of detection nodes, an optical communication receiving demodulation module and a data processing module; and 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 through a friction nanoelectric generator, use the sensing modules to collect various types of sensing data, and modulate and transmit the sensing data through the optical communication modulation transmitting modules, and the optical communication receiving demodulation module correspondingly receives and demodulates the sensing data, and transmits the sensing data to the data processing module for processing. The processing process comprises the steps of fusing similar sensing data by using a weighted least square method, analyzing heterogeneous sensing data by using a fuzzy comprehensive evaluation method, and finally obtaining a monitoring result. The precision of the data collected by the sensors is improved through two-layer analysis of the data, and the effectiveness and the reliability of a data fusion output result are improved. The detection nodes have the characteristics of small size, light weight and self power supply.

Description

Technical field [0001] The present invention relates to wireless optical communication field, particularly to a self-powered multi-line transmission line monitoring system for sensor data fusion. Background technique [0002] Environmental effects due to transmission lines in the operating state complex, ice, and lightning dancing phenomenon will cause the base parameters (such as temperature, vibration and sag) has variation, the safe operation of the transmission lines need to sense equipment for these parameters were aware and monitoring, in order to advance the security warning. However, the conventional online monitoring program monitoring data transmission line single wire data monitoring prior isolation monitor often only a two environments parameter, the more one-sided results; and there is the problem of limited scope of monitoring, the monitoring is often limited to a range of a single small area around the sensor, ignoring other areas of the transmission line parameter...
