Abstract

This paper introduces an automatic parking toll management system based on AT89C51 singlechip. The system adopts infrared detection and charging method which is more superior than the traditional parking charging method. The required storage capacity is small, with automatic opening and closing door function, automatic billing function, display function (display parking lot status, query function, and the charge mode can be adjusted to make the system more flexible. The automatic parking system is simple in operation, low in price, convenient in installation and debugging, and can solve the problem of the management charge of the temporary parking lot. Automatic parking charge management The system has the advantages of simple operation, low price, convenient installation and debugging, and can meet the requirements of managing the temporary parking lot. The actual development and use of the system will greatly reduce the management costs and manpower of the temporary parking lot and improve the utilization efficiency of the temporary parking lot. In addition, the automatic parking charge management system can easily realize information encryption and various functional extensions, and can become a general parking fee management system through improvement.
