Parking Charge Management System
Abstract:With the continuous progress of social economy and science and technology, the
continuous development of the city has greatly improved people's living standards. In
the modern city, there are still many old residential areas. These old residential areas
are not very ideal for the design of the parking lot in the residential area, and lack of
foresight, which leads to the problem of difficult parking today. The parking charge
management system is mainly composed of three layers, including perception layer,
data transmission layer and application layer. The rc522 RF module in the perception
layer scans and identifies the information of registered user card when the vehicle
enters and leaves the warehouse, and the infrared detection module detects the parking
data of all parking spaces in the parking lot in real time. After that, the data
transmission layer will transmit the user's corresponding card information and parking
information to the upper computer through the serial port under the data of the sensing
layer, and the underlying data of each module of the sensing layer will be transmitted
to the main control chip. After receiving the information, the main control chip will
display the corresponding information on the 12864 LCD screen and control the motor
to rotate the analog gate switch. The application layer includes a simple upper
computer software, which will store the data into the access database after receiving
the data from the data transmission layer, so as to facilitate the future data query. At
the same time, the upper computer software can also query and modify the user
information and transmit the modified information to the lower computer through the
serial port. The parking charge management system is convenient for the parking
management of the parking lot administrator, which effectively solves the problem of
the management of the parking lot in the old community. The design is simple and
easy to understand, and the price is affordable. Under the large population
environment in China, it also has a certain practical value.
