AUTOMATIC RAIN OPERATED WIPER
ABSTRACT
Over the past two decades, the automotive industry has aggressively researched ways to exploit modern computing and electronic advances in the development of safety, reliability, and entertainment technologies for vehicles. With drivers exposed to an ever increasing number of distractions, automatic rain-sensing wiper systems become an even more appealing feature, as they work to minimize the time the driver must take his/her hands off the wheel. Most traditional systems offer intermittent as well as variable speed operation. The traditional wiper system however requires driver constant attention in adjusting the wiper speed .Traditional windshield wiper speed constantly varies according to time and vehicle’s speed. Because the manual adjustment of the wiper distracts driver's attention, which may be a direct cause accidents. This is review paper for automatic wiper in various method and also explain the basic skeleton for adjust speed of wiper automatically cording to the amount of water on the windshield and in addition with also in advance removal of moisture inside the car while raining. The system activates the wiper to operate in full automatic mode and detect moister using CAN technology
INTRODUCTION
I have pleasure in introducing AUTOMATIC RAIN OPERATED WIPER, which is fully equipped by sensors circuit and wiper motor. It is fully equipped and designed for Automobile vehicles. This forms an integral part of best quality. The Automatic rain operated wiper system is a fully automation design. This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased. Degrees of automation are of two types, viz. Full automation, semi automation. In semi automation a combination of manual effort and mechanical power is required whereas in full automation human participation is very negligible
HISTORY
The inventor Mary Anderson is credited with devising the first operational windshield wiper in 1903 An Anderson's patent, she called her invention a "window cleaning device" for electric cars and other vehicles. Operated via a lever from inside a vehicle, her version of windshield wipers closely resembles the windshield wiper found on many early car models. Anderson had a model of her design manufactured, then filed a patent (US 743,801) on June 18, 1903 that was issued to her by the US Patent Office on November 10, 1903 born inventor James Henry AP John (1845–1914) devised a method of moving two brushes up and down on a vertical plate glass windscreen in 1903. This was patented in the UK
WORKING
The battery supplies the power to the sensor as well as rain operated motor. Wiper motor is automatically ON during the time of rainfall. The senor is fixed in the vehicle glass. The conductive (Touch) sensor is used in this system. It senses the rainfall and giving control signal to the control unit. The control unit activates the wiper motor automatically.
IMPEDANCE SENSOR
The sensor output voltage span seldom equals the analog to digital converter (ADC) input voltage span. Sensor data is lost and/or ADC dynamic range is not fully utilized because the spans are unequal, start at different DC voltages or both. In Figure 1(a) the spans are equal but offset This situation requires level shifting to move the sensor output voltage up by one volt so the spans match. In Figure 1(b) the spans are unequal, but no offset exists.
This situation requires amplification of the sensor output to match the spans. When the spans are unequal and offset as is often the case, level shifting and amplification are required to match the spans.
IR SENSOR
The photo depicts the schematics for an infrared sensor which allows you to detect an object's distance from the robot. The big picture problem is attach this infrared sensor on both wings of the aerial robot. Attaching these sensors on the wing tips will help the robot navigate through the halls of any building.. This tutorial shows you how to construct and test one infrared sensor and takes approximately 3 hours to complete
MICROCONTROLLER
In a one line definition we can say "MicroController is a Processing Unit (just like CPU in Computer System), which takes input through its input channels, processes the data, does the required task and finally gives the output.". I think now You can easily understand what it exactly does.. Lets get into deeper, lets know how it looks like in physical ? , how it takes input? Where it stores data? How it performs task? How it provides the output?
A microcontroller looks just like a small IC, it may be rectangular or square and it is of few square centimeters in area. So, you can assume this as a very tiny IC.. Lets see how different MCUs locks like
OUTPUT SIGNAL MODULE
The Aqua Trend Signal Output Module (SOM) is designed to be used with the
Aqua Trend Network System. The SOM can be a stand-alone device, or it can
be part of an Aqua Trend interface with SOM.
The SOM provides two relays, each with normally open and normally closed
contacts rated at a maximum of (30 VDC, 5A) resistive loads,
and two analog outputs, selectable at either 4-20 or 0-20 mA using the
AquaTrend Interface
WIND SCREEN WASHER
As per the statutory regulations in some countries a screen washer must be installed to clean the driver’s side of the Windscreen. Most of the vehicles install an electrically-operated pump to supply water or cleaning fluid in the form of two or more jets for spraying on the windscreen. On some vehicles an extra pump is used for a separate headlamp wash system, and some of these vehicles are also fitted with headlamp wipers.
The small centrifugal pump is either fixed directly on to the water reservoir or fitted in the hydraulic line. A permanent magnet motor drives the pump and is controlled by a switch often operated from the wiper switch stalk on the steering column (Fig. 30.12). The pump is of self-priming type and a filter is installed at the inlet of the pump. Polythene tubing is used for the jets. A typical motor consumes about 3 A and supplies about 0.75 litre/min fluid at a pressure of 66 k Pa. During winter period a small quantity of meth ylated spirit is added to the water to lower the freezing temperature.
