Parking lot distribution line layout method and device, terminal and storage medium

The invention discloses a parking lot distribution line layout method and device, a terminal and a storage medium, and the method comprises the steps: obtaining a parking lot map and a power supply range of a selected distribution box, and obtaining a first distribution box number; obtaining the number of parking spaces according to the parking lot map, integrating the limit number of cable plugs capable of being loaded by each distribution box to obtain the number of second distribution boxes, and taking the larger value in the number of the first distribution boxes and the number of the second distribution boxes as the theoretical number of the distribution boxes; obtaining an initial position layout diagram of the distribution boxes according to the theoretical number of the distribution boxes, and processing the positions of the distribution boxes through a preset optimization algorithm to obtain an optimal distribution box position diagram of the distribution boxes; and extracting a topographic structure
