Distribution network real-time data storage and reading method and medium

The embodiment of the invention discloses a distribution network real-time data storage and reading method and a medium, and the method comprises the steps: classifying real-time data into equipment attribute data, topological data and online data; setting memory mapping structural bodies corresponding to various real-time data; mapping different types of real-time data into a memory according to the memory mapping structural body; real-time data and the number of accessed programs of the memory block corresponding to the real-time data are read through the count value mark record; and if the count value mark is reduced to zero, closing a database corresponding to the real-time data, and releasing a mapping memory of the real-time data. According to the embodiment of the invention, the real-time security and efficiency of the distribution network system are improved, and the real-time data can be effectively and safely processed at a high speed under the condition that the equipment capacity of the system is
