Parking system with function of automatic route planning

The invention relates to the technical field of parking systems and discloses a parking system with a function of automatic route planning. The system comprises a read sensor, a sensing card, a controller, a wireless communication module, a server, a GPS (global positioning system) positioning module and radio-frequency equipment. When the server receives a selection instruction, a current road crossing of a vehicle is appointed as a current node, and all of next-step process nodes adjacent to the current node and capable of reaching a target node are searched in a map database of a parking lot; the server checks quantity of vehicles on a route, communicated with the current node, of each process node according to a road condition table, selects the next-step process node with the route having fewest vehicles as an optimal process node, and sends position information of the optimal process node to the controller; the controller sends the position information of the optimal process node to an electronic displa
