Abstract: The invention relates to a system for the management of a parking zone with chargeable parking spaces for vehicles, in particular of a parking zone sited at or on a public road, comprising an automatic machine for the payment of a parking fee for a parking space, said machine being assigned to the parking spaces. A parking-zone management system is provided which can indicate the current occupancy status of the parking spaces of the managed parking zone in an up-to-date manner and as accurately as possible, whereby at least one vehicle detector which is configured for determining the occupancy status of the parking space is arranged on each parking space, and whereby communication means, by means of which data representing the occupancy status can be transmitted, is provided for wireless data transmission between each respective vehicle detector and the automatic parking-fee machine.

Abstract: A money-operated machine is disclosed, such as a ticket machine for parking, for example. The machine includes a changeable cashbox used to receive money, which can be changed at given time intervals. The machine further includes a rechargeable voltage source for supplying the electric consumers of the machine with power. A method is disclosed for maintaining the money-operated machine. By integrating the voltage source into the cashbox, it is possible to form a common change unit. As a result, the money-operated machine requires less servicing since the cashbox can be changed and the voltage source can be charged in a single work step.
