In this embodiment, by defining the generation source, transmission path and processing end point of the data and correspondingly setting the monitoring mechanism, a reliable power carrier monitoring network is facilitated to be built, the power carrier communication channel can be accurately evaluated, and real-time transmission of elevator operation information is ensured.
In some possible embodiments of the present invention, the step of comparing and analyzing the transmission status data and establishing a data noise influence model of the power carrier communication channel includes:
extracting signal quality index data (such as signal-to-noise ratio, bit error rate, phase-locked state and the like) and environmental noise data (such as noise type, frequency range, amplitude and the like) from transmission state data of a channel;
preprocessing such as correcting, synchronizing and interpolating is carried out on the signal quality index data and the environmental noise data, so that the signal quality index data and the environmental noise data are aligned on the same time sequence;
adopting a statistical analysis method, such as correlation coefficient analysis, regression analysis and the like, to determine a correlation analysis result between the signal quality index data and the environmental noise data;
based on the correlation analysis result, adopting methods such as linear regression, nonlinear regression, neural network and the like to establish an influence model of noise factors on the channel quality index;
and verifying the model effect by using the newly collected transmission state data and noise data, and optimizing the model according to the verification result to obtain the data noise influence model.
Therefore, the root of the power carrier communication quality problem can be identified and noise reduction optimization measures can be guided through the noise influence model established through data driving.
In some possible embodiments of the present invention, the step of comprehensively weighting from several dimensions of transmission rate, transmission stability, interference immunity and security according to the data transmission channel state evaluation model and the data noise influence model to evaluate the power carrier communication channel to obtain the first evaluation data includes:

according to the determined weight, weighting and summarizing the scores of all the evaluation dimensions to obtain the comprehensive evaluation score of the power carrier communication channel;
