[Abstract]:Based on the propagation characteristics of optical waveguide boundary and artificial neural network, an on-line pollution monitoring device is introduced, which can simultaneously monitor the equivalent salt density and grey density of insulator surface of transmission line. Based on the detailed analysis of the influence mechanism of the surface fouling layer on the total reflected beam, the design scheme of the optical waveguide and the light source is proposed. A large number of sample data were obtained through the calibration tests under different humidity, different pollution grades and different lime-salt ratios, and an artificial neural network model was established and trained accordingly. The test results and operation practice show that both the salt density and grey density can be monitored simultaneously by using the device and the embedded neural network model after training, and the precision of the test meets the requirements of relevant standards.
