摘要: Parking meter carries photosensor directed at the controlled parking space. The operator of a parked car energizes the meter by coin insertion and meter cranking and thus activates the photosensor. When the vehicle is moved out of the parking space, the photosensor detects the movement and resets the parking meter to zero.
