Discrete data storage method and system

The invention provides a discrete data storage method and system, and the method comprises the steps: building a grid system according to a distribution region of discrete data and a preset grid size, and constructing a search circular ring set corresponding to each grid vertex by taking each grid vertex in the grid system as a circle center; traversing each search circular ring corresponding to each grid vertex, and performing first weighting processing on each discrete sub-data according to the distance between each discrete sub-data covered by the current traversal circular ring and the circle center of the current traversal circular ring to obtain a plurality of first weighting data corresponding to each grid vertex; according to the outer circle radius of the search circular ring where the first weighted data are located, second weighted processing is conducted on the multiple pieces of first weighted data corresponding to the grid vertexes, second weighted data corresponding to the grid vertexes are obt
