The automatic toll e-ticketing system is the approach used for the vehicle when it reaches the toll plaza, this is detected by using Infrared Proximity Sensor. RFID tags are used to read each vehicle with the help of RFID reader. An IR receiver is used to receive these pulses and sends it to a controller (MSP 430 Launch pad), which then transmits the vehicle number through the RF transmitter located in vehicle. We assume that vehicles have 16-bit identification numbers. The RFID [3] tags to readers read the signal and information about vehicles owners. These RF signals are received by an RF receiver at the toll plaza, which send data to a computer’s parallel port. A software program running on the computer retrieves vehicle details from its vehicle database. Depending on this information, appropriate toll tax is deducted from the pre-paid account of the vehicle’s owners [8]. The owner receives an SMS message on his/her mobile about the details of the payment [1]. If the balance in the owner’s account is low or if the vehicle is not equipped with an RF system, the toll gate remains close. Next method proposes a very simple method for enhancing the performance of infrared electronic-toll-collection systems, in such a case, the vehicle owner will have to pay the toll tax in case and collect the receipt, Figure 2 explains the concept in the form of a block diagram. We need a system for handling violation and acknowledgement when a vehicle does not have an RFID module installed, a vehicle’s ID number is not found in the database, or a driver has insufficient funds to pay toll [9]. If an acknowledgement is not received in a predefined time from the database, the toll plaza gate remains closed. Existing automatic toll collection techniques incur power loss since the receiver is continuously turned on, even when no vehicle arrived at a toll plaza [2].In our technique, only the IR sensor is turned on to detect the arrival of vehicles. Only when a vehicle is detected, RFID Tag to RFID reader reads the data.
SOFTWAREIMPLEMENTATION A.MICROSOFT ACCESS For secure and easy access of the database, we used Microsoft Access which is relational database management system from Microsoft Corporation.Microsoftaccess is supported by Visual Basic for Applications, an object-based programming language that can reference a variety of objects including DAO (Data Access Object). B.VISUAL BASIC Visual Basic 6.0 was used to interface the microcontroller with the personal computer in the e-toll plaza. The inputs from the microcontroller are given to the PC’s parallel port and this Data is retrieved by VB 6.0 software program, which manages the database. On receiving the input from the MSP430G2553 microcontroller, the program deducts the toll amount from account balance, returns success or failure acknowledgement to the controller and runs an executable file to send the transaction statement as SMS to the owner’s mobile number from the database. See figure8 which show the GUI. C. SENDING SMSWe made use of SMS send, Message to be sent are register in “SEND_SMS”. The transmission is activated by setting the START_SMS parameter once an open source software which helps connect the mobile phone as a GSM modem to the computer via a data cable. The software uses the SIM card in the mobile phone to send the SMS. The mobile is connected to the computer via COM. The operations of the software are automated using a Message Loop (default). It is wise to call this function many times per second in a loop; otherwise, you will have a slow or unresponsive GUI. COM extensions provide a common interface for working with software applications in a Microsoft environment. Applications have defined COM objects that can be used in AutoIt (and other programming languages) to manipulate the applications and perform tasks within them. To use COM objects, you must know the object name and its properties and methods. C.IAR Workbench IAR Workbench Kick start version provided by Texas Instruments was used to develop the microcontroller programs as it was user friendly and has both simulation and debugger mode. This also makes the process of loading the programs to the controller faster and easier.
The security at the toll booth will improve in this system and it will become possible to detect stolen vehicles. Since cars do not have to stop at the toll booth, savings on fuel from repeated stops for vehicles, and reduction in accidents. There are several limitations of the proposed system. It requires a user to have a dedicated prepaid account. Since the infrared proximity sensor is used in detecting the arrival of vehicles, there can be interface from external source of light. Since highways are operated in two directions, If computer of the toll plaza are connected in a network, then a vehicle from one state can use the automated facility of a toll booth in another state. The unique identification number of vehicle can be increased to larger number. Vehicle theft can be prevented by anti-theft alarm along with this kit.
In this Paper, the concept of Automated toll e-ticketing using MSP430 Launch pad. We have used an innovative approach where a traveler will be able to pay the toll while in motion using RFID communication technology. Through this process of toll collection will save time, effort, and man power. How many vehicles passing through the toll gate stored in a database. We can also find out a vehicle how many times passing through the toll gate in a day. The improvement can be done to develop a multi vehicle amount deducted and send a SMS at a time multi vehicle.
