Fully automatic parking time control - is based upon charge rate fixed by detection of number of vehicle occupants

摘要

The fully automatic car parking control system has a monitoring station located in front of the barrier that detects the number of occupants and indicates a related charge value. Infra red detectors (13-22) are positioned around the vehicle at window and door height and respond to the presence of passengers. Each sensor signals a circuit (23-26) that connects with the control unit. Once the charge has been paid the barrier opens. ADVANTAGE - Automatic control of charge and access.
