Embedded Based Conveyance Authentication and Notification System
S. Dharanya,A. Umamakeswari
International Journal of Engineering and Technology , 2013,
Abstract: Amidst the rapid increase in population and urbanization, the use of automobiles is increasing rapidly. Though there are improved safety and security features with advancement in technology, there are no vehicle regulatory systems that provide automation in vehicle monitoring and act violations. The main objective of the work is to have a centralized server based monitoring of vehicles with an advanced security system realized in two levels of verification (password and RFID card i.e. driving license) for engine ignition. In addition to this, the centralized server maintains two separate databases i.e. one for the vehicle and another for the person who rides it. A unique id is allotted for the vehicle and RFID card (smart card driving license) can be used to identify the object. The unique identifiers linked to the respective person’s bank account debits the penalty/toll fare when the vehicle passes by toll gates/check posts. This provides a way for reducing any possibility of corruption in motor vehicles section as the penalty will be deducted straightforwardly from the person's account by an automated system.

V. Divya,A. Umamakeswari
Journal of Artificial Intelligence , 2013,
Abstract: Agriculture sector is the backbone of Indian economy. With the advent of electric motors, the burden of manual irrigation by farmers has mitigated a lot. But still frequent power cuts and voltage fluctuations have affected the proper irrigation of fields in many remote areas. There have been several innovative efforts to automate the irrigation of fields. This study proposed an automatic irrigation system based on voice commands from an illiterate farmer. A separate module for speech to text conversion is interfaced to the farmers mobile. The module uses the Hidden Markov Model for speech recognition and a Field Programmable Gate Array (FPGA) or processor based system to store the texts. Besides this, the system also includes a wireless network based remote monitoring of the field’s temperature and moisture. The voltage monitoring unit informs the farmer about the power availability in the field. The control unit is based on the Peripheral Interface Controller (PIC) controller and relays connected to the various valves. Controller shuts off the motor if the measured values of temperature and moisture have reached the prefixed levels. The proposed system would reduce the hardships of the farmer and helps in efficient utilization of water in the fields.

Abstract: In this wireless communication era, mobile phones have become a necessity in the common man’s life. Besides being capable of making calls and sending messages, the latest advancements in mobile phones facilitate them to connect to the internet also. With these capabilities, there has been an unprecedented use of mobile phones in many areas of automation. One such area where mobile phone can help with the automation is irrigation process. The main aim of the work is to simplify the method of irrigation using vocal commands through the mobile phone. The Farmer just needs to call a fixed number and utter the control commands through his phone. The control system at the field involves a PIC microcontroller interfaced with GSM modem to receive the command from the farmer and a voice recognition unit which decodes it. The motor is turned on/off according to the decoded commands by the controller. In addition, the system also sends back a message to the farmer’s mobile about the action that has taken place. The power detection and battery backup unit helps in detecting the power availability in the field and inform the farmer about the same, even if the there is no supply at the field. The moisture sensor attached to the system helps in collecting the moisture content of the soil and switch off the motor after it reaches the required value.

Abstract: Health is an important factor of every human being. Remote health monitoring messenger is needed for the people to reduce their inconvenience in travel to hospitals due to ailing health. Ill-patientrequires accurate decision to be taken immediately in critical situations, so that life-protecting and lifesaving therapy can be properly applied. In recent years, sensors are used in each and every fast developing application for designing the miniaturized system which is much easier for people use. A remote health monitoring messenger informs the doctor about the patient condition through wireless media such as Global System for Mobile communication. The system specifically deals with the signal conditioning and data acquisition of heart beat, temperature, and blood pressure of human body. The Heart beat sensor is used to read the patient’s beats per minute (bpm) and temperature sensor to measure the body temperature of patient externally and pressure sensor to measure the level of pressure in blood. Signals obtained from sensors are fed into the microcontroller for processing and medicine is prescribed as first aid for patient to control the parameters through visual basic. A message is then sent to the doctor for further actions to be taken for treatment of patient after first aid. The system has a very good response time and it is cost effective.

U. Rajkanna,K. Guna Sekaran,D. Manivannan,A. Umamakeswari
Journal of Artificial Intelligence , 2012,
Abstract: In forging and rolling industries, the furnace is used for melting. The temperature of the furnace is controlled by supplying air-fuel combination, flow of electron, inflow of coal etc. Depends on the type of furnace it will vary. The temperature is measured by using pyrometer type sensors or any contact type sensors. Fully automated furnace, temperature is measured and transmitted to control room through a wired connection. Similarly control on furnace also carried out by wired connections from the control room. In wired network, transmission between control room and furnace and vice versa needs lengthy and confusing wire connections. Installation cost is also high. In this proposed study, the amplified value of the temperature sensor is transmitted to the controller unit by radio frequency waves. For transmission highly secured XBee is used. The controller unit receives the temperature serially by using another XBee module. The controller unit displays the temperature locally. Controlling value of the flow of electrons is transmitted to another controller using the XBee module. So that temperature of the furnace is maintained with ±1°C. In the entire process LPC2148 processor is used. By implementing this technique accident due to operator carelessness can be reduced. This technique is easy to implement and also acquired at low cost.
