Embodiment 1

[0060] This embodiment provides a central air-conditioning fault performance detection system based on big data processing, including a management module, a background server module and a monitoring module;

[0061] The server module includes a deep belief network module, a failure analysis module and a database module;

[0062] The deep belief network module is used to train and deploy the deep belief network model. The deep belief network module uses pre-collected data to train the basic deep belief network fault monitoring model before the deployment of the overall system. The data is collected and organized, and the model is retrained and deployed regularly to ensure that the model can continue to accumulate with the training data;

[0063] The fault analysis module is responsible for processing the fault phenomenon information returned after the abnormality is detected by the model, and performing comparative reasoning from the fault analysis knowledge base according to t...

Abstract

The invention discloses a central air-conditioning failure performance detecting system based on big data processing. The central air-conditioning failure performance detecting system comprises a management module, a background server module and a monitoring module; the background server module comprises a depth faith network module, a failure analysis module and a database module; the managementmodule manages knowledge base and a factbase for constructing failure analysis; and the monitoring module is used for monitoring related data parameters of a central air-conditioning in real time within the monitoring range. The central air-conditioning failure performance detecting system can monitor the real-time operating state of the central air-conditioning in real time, can give out an alarmwhen equipment operates abnormally and diagnoses the failure type, can modify and perfect a system knowledge base through the background management module, can precisely judge the failure informationand has actual using value.

Description

technical field [0001] The invention relates to the technical field of air conditioner fault monitoring, in particular to a central air conditioner fault performance detection system based on big data processing. Background technique [0002] Air-conditioning system faults can be divided into hard faults and soft faults according to the severity of the faults. Hard faults refer to faults that completely fail and inoperable equipment and meters, such as water pumps that cannot operate, fans that cannot operate, and valves that are blocked. Soft faults refer to faults that cause partial failure of equipment and instruments and gradually degrade performance, such as heat exchanger scaling, refrigerant leakage, sensor drift, unreasonable water flow, etc. Hard faults generally occur suddenly and can directly cause equipment or systems to be in a state of paralysis. They are relatively serious but relatively easy to detect faults. Soft faults are also called performance faults, w...
