The invention discloses a parking
toll collection method and
system. The method comprises the following steps that an entrance device, when recognizing an entering vehicle, obtains vehicle entry information including a vehicle
license number and
entry time, and sends the vehicle entry information to other equipment in a network; and an exit device, when recognizing a leaving vehicle, obtains vehicle departure information number including the vehicle
license number and departure time, matches the vehicle
license number of the leaving vehicle and the vehicle
license number of the entering vehicle stored in the exit device to obtain the
entry time corresponding to the vehicle
license number of the leaving vehicle and calculate a parking fee based on a difference between the departure time of the leaving vehicle and the
entry time corresponding to the vehicle
license number of the leaving vehicle, and outputs parking fee information related to the parking fee. The method and
system share the data between the entrance device and the exit device through the networking technology, reduce cost, and shorten chargeable time.
