Online monitoring system and method for elevator car system

The invention provides an elevator car system online monitoring system and method. The system comprises a model optimization module which is used for establishing an elevator car aerodynamic characteristic state parameter model under a multi-working-condition airflow field and carrying out parameter analysis on the model to obtain a parameter data set under a first operation mode; the data monitoring module is used for acquiring parameters required by the optimization model through detection equipment and processing the parameters to obtain an effective detection data set, and the effective detection data set is provided for the model optimization module and the data processing module; the data processing module is used for analyzing the effective detection data set to obtain the elevator operation condition so as to generate a regulation and control instruction; and the remote control module is used for receiving the regulation and control instruction so as to remotely control the elevator based on the param
