Power distribution network management and control method and system based on Internet of Things, terminal and storage medium

The invention relates to the technical field of power distribution network operation and maintenance, and particularly provides a power distribution network management and control method and system based on the Internet of Things, a terminal and a storage medium, and the method comprises the steps: building communication connection with an Internet of Things terminal, and obtaining power grid monitoring data from the Internet of Things terminal; performing abnormality checking on the power grid monitoring data according to a preset standard threshold value to obtain abnormal data; mining the association degree between the abnormal data items corresponding to the abnormal data by using an association rule algorithm, and dividing the abnormal data items with the association degree exceeding a set threshold value into the same group; and generating a maintenance task for each group of abnormal data items, and issuing the maintenance task to a maintenance terminal. According to the method, the abnormal data are g
