VEHICLE PARKING MANAGEMENT SYSTEM TO WEB SERVER USING GPRS COMMUNICATION (HTTP AND TCP/IP PROTOCALS)

Abstract:

Vehicle parking management ad issue tickets updates to web server using GPRS communication via TCP/IP and HTTP protocols with hard copy ticket printing through Thermal Printer.

In these modern days everything is getting automated, thus reducing the manual and effort and save lot of time. Paying bills for home needs is in manual process which takes lot of time and even there are possibilities for human error. In this project we avoid such manipulations and save time. Instead of written signed paper bills, E writing (printing) is the best option to avoid human errors and saving time.  Here in this project we use thermal printer for printing text data on Thermal paper. We could update data to web server wireless protocols. These web connected applications belong to server client relation. TCP, UDP and HTTP protocols are used in this concept. Data transfer to web server through GPRS (General packet radio services) communication. We can transfer long data through this GPRS. Many Embedded Networking applications fall under this model only. This project consists a 16X2 LCD and 4X4 keypad. Thermal printer is also connected to microcontroller but it was optional. After parking the vehicle, the service person enters the vehicle license no, vehicle type and price. Microcontroller gets this information and develop TCP stack with standard format. This data stack is printed on thermal paper using thermal printer. Also this stack data will be sent to web server. Web server consists of particular IP address and port number. Web server maintain data base of all tickets information with respective time. Owner could see this information in web server from any where I the world. This system avoids ticket manipulation from service men. The advantage of this project is vehicle details are stored in web server. This is very helpful for transport and cop departments.  

 Here we use 8051 microcontroller with 5V DC Power supply.  Serial (UART) protocol is primary concern here. The main heart of this project is GSM/GPRS modem which works on GPRS AT commands. 16X2 LCD is connected to microcontroller through Digital I/O lines. AT keyboard is interface to microcontroller with PS/2 connection. 4X4 keypad is directly connected to microcontroller. Thermal printer connected to microcontroller serially and it works on ESC/POS commands, but microcontroller has only one serial port so that we have to use serial shift driver (built with relays or driver ics – depends on availability and possibility).
