PROGRAMMABLE LOGIC CONTROLLER (PLC)

Automation devices such as controllers and data systems and or services. Systems and methods are provided that receive statements or other unit of data interaction from an automation device, provide the statements to an appropriate system or service for processing, and optionally return a response such as a result set. Furthermore, in accordance with an aspect of the invention native controller code, variables, or tags can be mapped to stored data, procedures or combinations of data and/or procedures and updated automatically or semi automatically. A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. PLCs are used in many industries and machines. Unlike general-purpose The subject invention pertains to facilitating communication between industrial computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.

Smart Dust

Advances in hardware technology has enabled very compact, autonomous and mobile nodes each having one or more sensors,computation and communication capabilities ,and a power supply. The Smart Dust project is exploring whether an autonomous sensing, computing and communication system can be packed into a cubic-millimeter mote to form the basis of integrated, massively distributed sensor networks. It focuses on reduction of power consumption, size and cost. To build these small sensors, processors, communication devices, and power supply ,designers have used the MEMS (Micro electro mechanical Systems)technology.

MISSILES AND THEIR GUIDANCE BY GPS

A weapon that is self-propelled or directed by remote control, carrying conventional or nuclear explosive."the plane disintegrated after being hit by a missile launched from the ground".basically there are three types of missile among them ballistic and cruise are there based on their mode of path.Ballistic Missile: ... Since it depends on gravity to reach its target, it's called aballistic missile. Ballistic missiles that fly above the atmosphere have a much longer range than would be possible for cruise missiles of the same size. Ballistic missiles can travel extremely quickly along their flight path.In other words, in a military context, a rocket is an unguided, rocket-powered weapon, with no steering ability. A missile is a self-propelled weapon, often rocket-powered (but not always), that has some kind of guidance system so that it can steerin flight, towards its target.

ELECTRONIC TOLL COLLECTION SYSTEM

Today, due to the increase in the vehicles, there is a lot of gathering of the traffic at the toll booths. The main reason for this traffic at the toll booths is due to the manual working of the toll tax collection at the booths. Each vehicle on an average needs to stop at the toll booth for about a minute for the payment of the toll tax. In order to decrease this traffic we decided to work on the construction of a project which reduces the manual work and hence increases the vehicle speed passing by the toll booth. Also we decided to develop a project which allows the vehicles just to pass through the booth without stopping as a result reducing the traffic gathering at the toll collecting booths.
