Electronic Toll Collection System using Passive RFID

This paper focuses on an electronic toll collection (ETC) system using radio frequency identification (RFID) technology. Research on ETC has been around since 1992, during which RFID tags began to be widely used in vehicles to automate toll processes.

The proposed RFID system uses tags that are mounted on the windshields of vehicles, through which information embedded on the tags are read by RFID readers. The proposed system eliminates the need for motorists and toll authorities to manually perform ticket payments and toll fee collections, respectively.

Data information are also easily exchanged between the motorists and toll authorities, thereby enabling a more efficient toll collection by reducing traffic and eliminating possible human errors.

Automated Toll Collection System Using RFID

Rede Tacton Seminor/ Project

What is RedTacton?

RedTacton is a technology that bridges the last networking gap, creating the HAN – Human Area Network, connecting the last meter.  It works by utilizing the electric field on the surface of the human body to transmit data between a RedTacton receiver and other devices.  Data can be transmitted at up to 10 mbps.  According to Technology Review, the “transceiver combines an optical receiver circuit equipped with a super-sensitive photonic electrical field sensor and a crystal to transmit data.”

Currently, RedTacton is gearing up to compete with Bluetooth, Zigbee, IrDA (infrared data association), UWB (ultra wide band), and other wireless communication forms.  These competing technologies are different in that they use radio frequency or light to transmit data short distances.  They also tend to work at slower speeds that RedTacton which, as mentioned before, uses the body’s electrical field to transmit at a high speed.  Additionally, since RedTacton requires touch and has a low potential for interference, it it much more secure than the competition.

Project On Frost Alarm

 

Description
A simple thermistor triggered switch with adjustable threshold. It triggers with cold temperatures so may be used as a frost alarm or cold temperature switch.

frost alarm


Circuit Notes
The thermistor used has a resistance of 15k at 25°C and 45k at 0° Celsius. A suitable bead type thermistor can be found in the Maplin catalogue. The 100k pot allows this circuit to trigger over a wide range of temperatures.

DGS DRIVING GUIDANCE SYSTEM BASED ON WIRELESS SENSOR NETWORK

In recent years, the desire to connect all electronic computing devices together and to embed computing devices in almost everything has increased. Although they can be connected through wired lines, it is more convenient and effective to use wireless links when we consider the large number of pervasive devices in the environment.
Wireless sensor networks (WSN) are one of the enabling technologies for such a ubiquitous computing world. This is especially true in the telematics field where WSNs can be used to provide useful information such as road condition and traffic speed for safe driving. Currently, this information is detected in a wired way using loop detectors and sensors. Furthermore, they are very expensive and it is difficult to install and maintain them. In the proposed system these things will be done through WSN.
SYSTEM DESIGN:
The system present with the WSN based DGS system architecture which consists of the SMS and the WPS. The WPS (Weather information Providing Sub-system) is used to provide road condition information (e.g., dry, icy, wet, etc.) to drivers and the SMS (Speed Measurement Sub-system) is used to measure the speed of a vehicle and to control a VMS(Variable Message Signboard) to guide the driver to keep to the regulated speed.
HARDWARE & SOFTWARE REQUIREMENTS:
1)Hardware components: PIC 16F877A, 2x16-LCD, MAX232, RS232, Sensors, RF TX, RX
2)Software tools: Development tool – MPLAB v7.42, Hardware Compiler - HI-Tech PICC, Programmer - PIC Flash, Hardware Simulation tool - Proteus v6.9 Sp4

DESIGN AND CONSTRUCTION OF TILT BASED TOUCH FREE MOBILE PHONE

This project aims at designing a GSM mobile with the help of a MEMS sensor to help for a friendly hardware interaction for the user. The device is designed by interfacing a Micro Electro Mechanical Sensor (MEMS) and a GSM modem. An onboard computer (Microcontroller) controls these two hardware modules. These three combined to form the project that can achieve the following innovative features.
1) Horizontal Right Tilt based Phone Book (forward) reading system.
2) Horizontal Left Tilt based Phone Book (backward) reading system.
3) Vertical Upward Tilt for calling the phone number.
4) Vertical Downward Tilt for disconnecting the call.

This kind of hardware interactions are made possible with the help of the MEMS technology. This kind of mobile designs are helpful for user who are interested for a fast and less complex operations and also for the illiterates who least prefer for lot more button operation.
The objectives of the project are achieved by making use of an onboard computer. Onboard computer which we are making use can also be termed as a control unit or microcontrollers. Microcontroller interfaces with MEMS based tilt sensor and also with GSM Modem. GSM modem interfacing is done using Serial Communication and AT commands. This system also consists of a graphical LCD for better visibility. This displays the control options for tilt based commands, Address book, Mobile operator name and Number dialing/disconnection information. This system also enabled with the power saving features like disconnecting the power supply to GLCD incase of non-usage of mobile phone for few seconds.
The MEMS sensor is the input module of the project and provides the information about the tilt in different directions. While the GSM modem is used for remote communication and it catch holds of a SIM card. It is operated with out the need of any control button interface and for this the control makes use of AT commands as per the interest of the user (as per the tilt).
The main features of this project are:
1. User friendly operation.
2. Dynamic phone book display with respect to the horizontal (left/right) tilt angle.
3. Dynamic calling option with respect to the forward vertical tilt angle.
4. Dynamic calling option with respect to the backward vertical tilt angle.
5. Very easy to operate.
6. GLCD with backlight control.
7. Power saving mode of operation.
8. Activities display on GLCD.
9. Buzzer for audible alerts.
