Fault detection method and equipment for drainage pipe network, server, and storage medium

A fault detection method for a drainage pipe network, comprising:

• acquiring a first liquid level time series collected at a current node in the drainage pipe network;
• performing abnormality type identification according to the first liquid level time series to obtain an abnormal event type of the current node;
• performing hydraulic characteristic matching on the first liquid level time series and a liquid level time series of a neighboring node of the current node by using a fault diagnosis algorithm corresponding to the abnormal event type to obtain a fault diagnosis result corresponding to the current node;
• the liquid level time series of the neighboring node comprising:
• a second liquid level time series corresponding to an upstream node of the current node, and/or a third liquid level time series corresponding to a downstream node of the current node.
