Power grid slice updating method and terminal

The invention discloses a power grid slice updating method and a terminal. The method comprises the following steps: obtaining a change record of power grid equipment, combining slice geographic blocks of the change record through employing a pyramid slicing algorithm, and obtaining index change data of the slice geographic blocks; determining a display layer according to the slice geographic block, and calculating associated slice data before and after the power grid equipment data is changed in real time according to the index change data and the display layer, so as to obtain incremental slice data; and according to a file storage model of a pyramid algorithm, generating an incremental slice file from incremental slice data, and updating power grid slices based on the incremental slice file, and dynamically completing generation and pushing of a vector slice file online, so as to realize online updating of slice map service. The problem that off-line map cutting and publishing need to be carried out regula
