Design and Development of Automatic Timing and Charging System Based on
Untouched IC Card in Parking Lots LI Hong-jia, WEI Quan-li, XU Xiao-xiao, GUO Si-wen (College of Information and Scientific Technology, Qingdao University of Science and Technology, Qingdao 266042, China) Abstract: The designing idea of the system is put forward according to demand in intelligentized management in parking lots. The whole system is composed of entrance-machine, exit-machine and card-sender and their hardware circuits and software designing are discussed. The IC card reader which is the central part of the system hardware is introduced in detail.
