An Advanced Security System Integrated with RFID Based Automated Toll Collection System

Abstract

In the developing countries many crimes are happening at the highways and bridges. In this paper we have introduced a security feature which can resist the occurrence of those crimes. However, this system is based on RFID (Radio Frequency Identification) technology which replaces the traditional manual tolling system. In the existing automated tolling system RFID reader only detects the RFID card to deduct the toll amount according to the vehicle types. In our integrated system if the authority wants to block a certain type of vehicle or a specific vehicle, it can be done at the toll booth area. For this, a simple code text is sent to the system using GSM module and then the vehicle is blocked by not lifting the barrier even after deduction of the toll amount from the vehicle owners prepaid based account. In addition, this can also be done to block all the vehicles at the toll booth area in the bridges in case of emergency.

Existing System

Automated Toll Collection System.

Proposed System

In this paper we tried to design an embedded system to ensure a faster toll collection system along with security feature that will contribute a lot to stop crimes at the highways and bridges. It will also ease the work of the police authority to catch a criminal. The system performs the whole task by processing the data received through GSM shield from the police authority. However, the same concept can be implemented at the car parking system or any other security concern places. The real life model construction cost of the system is very less and sustainable too. We can improve the response time of the whole system by using more powerful RFID system. As a whole, the integrated toll collection with security system is very beneficial and effective system. The system is a compact hardware system which starts when a vehicle enters in the toll booth area. Then vehicle identification is done by detecting the value of the RFID tag which is attached to the vehicle. However, this identification is done by using RFID reader which is placed at the toll collection booth. If it founds valid tag, the overall process moves further. Moreover, the weight of the vehicle is measured by using FSR (Force Sensitive Resistor). The calculation of the toll charge is done in the database where the toll amount is predetermined according to the vehicle type. For truck or cargo which carries extra weight, the calculation is done by using a formula or method. Then the toll charge is debited and credited from the vehicle owners prepaid based account. Required information about the account, like-account number has to be recorded in the system database prior. A confirmation SMS will also be sent to the vehicle owners mobile number via GSM module. After that the servo motor will rotate and lift the barrier to pass the vehicle if access permission is not blocked by the authority.
