Abstract

The invention discloses a subway station air conditioner predictive operation and maintenance management method and system, and the method comprises the following steps: obtaining sensor information and non-sensor information of an air conditioning system through a detection device and an information storage device, and uploading the sensor information and the non-sensor information to an edge node unit in real time; preprocessing the sensor information and the non-sensor information through an edge node unit to obtain preprocessed data; performing data normalization processing on the preprocessed first part of data; by a cloud server, training and verifying the first part of data subjected to standard processing to obtain an information fusion model, a predictive maintenance model and a fault processing scheme model; by the edge node unit, performing normalization processing, fault prediction and maintenance scheme determination on the preprocessed second part of data in real time according to the information fusion model, the predictive maintenance model and the fault processing scheme model; and by the edge node unit, automatically maintaining the air conditioning system according to the determined maintenance scheme.

Description

technical field [0001] The invention relates to the field of intelligent air conditioners, in particular to a predictive operation and maintenance management method and system for air conditioners in subway stations. Background technique [0002] Due to its high efficiency, large transport capacity, fast and punctual, and low environmental pollution, the subway transportation system has achieved rapid development and has become an important part of the public transportation system. Due to their special structures and uses, each station of the subway needs ventilation and air conditioning systems for a long time to ensure a safe and comfortable riding environment for passengers. Therefore, it is very important for the good and stable operation of the air conditioner in the subway station. [0003] At present, the operation and maintenance management of air-conditioning system equipment in the subway system often adopts the following two methods: First, the monitoring system ...
