Smart Bike On Safety Helmet Report (1).docx

Sky Advanced Safety Helmet Abstract: Every year in India a large number of deaths occur due road accidents. Drivers on two-wheeler contribute significantly to these numbers. In a large number of two wheeler accidents, deaths occur because no preventive actions have been taken beforehand by the driver or those sitting in the two-wheeler. As greater risk is involved in riding a two wheeler therefore, it becomes essential to use protective guard while riding the vehicle. In our paper we propose one such security systems that make it mandatory for the user to wear a protective guard or helmet before riding a two wheeler. This system reduces the probability of a severe injury or death during an accident. We also take into consideration a prototype that has been developed for motor cycle riders.

INTRODUCTION There has been a sharp rise in the total number of deaths that occur due to road accidents in the past few years. Reckless driving, ignorance of traffic rules and absence of a protective shield have been some of the most important reasons for these deaths. The driver must have a line of defence in case an accident occurs survey performed in India confirmed that there were a total of 1,34,513 deaths due to road accidents in India in the year 2014. The number increased to 1, 42,485 in the year 2011. Accidents involving two wheelers are more dangerous due to the absence of protective guards like air bags and the direct interaction of the user with the environment. It becomes utmost essential for the users have a line of defence in case they encounter an accident. Fatal injuries to the brain are an important reason behind deaths due to the road accidents. Therefore, a person riding a two wheeler must wear a helmet in order to protect his skull. Riders wearing a helmet have a greater probability of survival during accident. Many riders however do not prefer to wear helmets due to in significant reasons. The traffic rules also do not affect these riders much. In our proposed safety system for two wheelers, we have proposed an approach that makes it compulsory for the user to wear a helmet. The two wheeler Would not start until the user wears a helmet and rides the two wheeler. We were successful in implementing a prototype for this human safety system.

LITERATURE SURVEY Review of Literature: This is a report about a smart helmet which makes motor cycle driving safer than before. The main aim of this project is that it makes sure that the biker can’t start the bike without wearing the helmet. A similar proposed work that has been put forward earlier which is based on the principle of pressure sensing that is wearing a helmet creates a pressure on the helmet and a data signal is passed to the transmitter which redirects the bike ignition control to turn on. Moreover the transmitter and the receiver modules used are IR based. However, both the technologies have certain drawbacks: DRAWBACKS:  Pressure can be created inside the helmet by putting any dummy material inside it. Thus the rider instead of wearing a helmet can create the required pressure by putting any dummy material inside the helmet. Hence the basic purpose of starting the bike by wearing the helmet can be easily by passed.  The IR technology is of short range.  IR modules work on the principle of line of sight.  IR based devices cannot move around while the transmission is in progress.  Keeping all these drawbacks in mind, we have a proposed system which overcomes all these problems. Instead of pressure sensor a unique technology of SKIN SURFACE POTENTIAL has been used which enforces the biker to wear the helmet for starting as well as riding the bike and cannot bypass it by any means. Moreover this system is RF based which not only has a long range but also eliminates the problem of need of line of

sight. Moreover RF based transmitter and receiver can be moved while the data transmission is in progress.

OVERVIEW: A smart helmet is a special idea which makes motorcycle driving safer than before. The main aim of the smart helmet is to prevent the biker from starting his bike until and unless he actually wears the helmet. It incorporates the concepts of GSM and GPS to track a location of the accident and to provide the victim prompt medical attention. The project also carries the concept of a TILT sensor which senses the tilt of the bike above a permissible limit (>60◦) and informs the family and friends of the biker about the accident by the concepts of GSM and GPS BACKGROUND: In today’s era, especially in the young generation, the craze of motorbikes is really remarkable. The middle-class families prefer to buy motorbikes rather than four wheelers, because of their low prices. As the bikes in our country are increasing, the road mishaps are also increasing day by day, due to which many deaths occur, most of which are caused due to most common negligence of not wearing a helmet. According to a survey of India, there are around 698 accidents occurring due to bike crashes per year. If accidents are one issue, lack of proper treatment is another reason for deaths. In India out of the 698 deaths occurring annually, nearly half of the people die due to lack of proper treatment in proper time. The many reasons for this are late arrival of an ambulance, no person at the place of accident to give information to the ambulance or parents, etc. This is a situation we observe in our day to day life; a thought of finding some solution to resolve this problem comes up with this idea of giving information about the accident as soon as possible because of TIME………!!!!!!!!! matters a lot. If everything is done in time, at least, we can save half the lives that are lost due to bike accidents.

Objective Of Project The objectives of this project are I. To design the circuit that can improve the safety of motorcyclists. II. To develop an Smart safety helmet for complete rider. III. To study and understand the concept of RF Transmitter RF and Receiver circuit in implementing the project.

PROPOSED SYSTEM: The idea of our work is that a biker must wear a helmet in order to start up his bike, otherwise the bike won’t start. It also gives information about the location, in case, the biker meets an accident. The location of the accident is given by a GSM module to the cell phones of family and friends, through an SMS. Sending the SMS regarding the accident alone cannot help the rider until and unless the location of the accident is also known. So as to trace out the location of an accident, we use a GPS module. Thus an SMS containing the information about the accident as well as the location (latitude and longitude) of the area is sent to the family and friends using a microcontroller.

Project descriptionTHE HELMET The helmet was a normal driving helmet that had been instilled with 4 infra-red sensors that were connected to an Arduino microcontroller board. This development board also had a CC-2500 wireless receiver/transmitter attached to it. The 89s52 was the brain of this section of the setup and was concerned with the transmission of messages to the receiver part as soon as the helmet is worn by a human being. A MAX-232 IC is used for conversion of data to RS-232 protocol.

Alcohole sensor A large number of road accidents occur due to excess alcohol consumption of drivers. Adding an extra alcohol meter to the helmet would ensure that the vehicle does not start if the driver has consumed a large amount of alcohol. Even if the vehicle starts its speed is restricted to a threshold in order to minimize the chances of accidents IR SENSOR One Infra-Red sensors have been embedded in the helmet. These sensors have a low logic level when there is no object present in their sensing range and change their state to a high logic level as soon an object is present in their range. This sensor when instilled in a helmet can be used for determining the presence of a human head inside the helmet. All the sensors will be high if a human head is present inside the helmet. The sensors are attached to an microcontroller that continuously monitors the logic levels of these sensors. The microcontroller signals the receiver section to stop the motor if all the sensor are not high. When all the sensors are high, the microcontroller sends a message to the receiver section to keep the motor moving. In case of real time

IMPLEMENTING THE SYSTEM ON AN ACTUAL TWO WHEELER Our initial aim is to implement this security system on an actual two wheeler, so that the security system may function in a real time environment. The receiver section can be used for switching the start button of a two wheeler and can be attached to the two wheeler.

ADXL 335 vibration sensor:

The principle of capacitive can be applied for measurement of non –contact type vibration , if the vibrating device or a related part of it is useable as a plate of a capacitor. In order to do measurements, a second plate is needed. Now the whole setup works like any common capacitor. The variation of the distance of the two plates is proportional to the capacity. An AC supply is connected to the capacitor. Depending on the space between the plates, a specific amplitude can be perceived by the sensor which can be used for further processing.

ALCOHOL SENSOR This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog output based on alcohol concentration. Today’s sensors, while featuring a high sensitivity to a wide gases variety, are very compact in size and have significantly reduced their power consumption to better adapt to portable solutions. Building a system with an Alcohol sensor is not as easy as it could appear. Despite the sensor could be treated, basically, as a variable resistor (which value depends on gas concentration in air) the practical implementation in a project should be done considering some design rules, especially if the final circuit is a device to be used in a field where reliability is strongly required (e.g. safety). As an example the internal elements of a sensor (heater and gas sensitive resistors) have to be constantly kept under control to avoid failures leading to a wrong alarm indication; furthermore, if the application needs to achieve a good measurement accuracy, factors like environment temperature, sensor life etc... have to be taken into account.

4.2 Applications  Breath Analyzer  Blood Alcohol Concentration Checker  Alcohol Gas Sensor

Features     

High sensitivity to alcohol and small sensitivity to Benzine Fast response and High sensitivity Stable and long life Simple drive circuit of 5V DC with analog output Operation Temperature: -10 to 70 degrees C

Warm up Time  The sensor needs 10 minutes of warm up time after first power is applied. After 10 minutes you can take its readings. During warm up time the output analog voltage would go up from 4.5V to 0.5V in variation down gradually. During this warm up time the sensor reading should be ignored . Using the Sensor  The sensor needs 5V to operate, Give regulated +5V DC supply, The sensor will take around 180mA supply. The sensor will heat a little bit since it has internal heater that heats the sensing element.

Testing the sensor Measure the output voltage through multi-meter between A.OUT and Ground pins or Use a microcontroller to measure the voltage output. Best way to check the sensor is take a bottle of after shave liquid and open the cap. Take the sensor near the bottle output. You will see increase in the readings.

GSM GSM is a mobile communication modem; it is stands for global system for mobile communication (GSM). The idea of GSM was developed at Bell Laboratories in 1970. It is widely used mobile communication system in the world. GSM is an open and digital cellular technology used for transmitting mobile voice and data services operates at the 850MHz, 900MHz, 1800MHz and 1900MHz frequency bands. GSM system was developed as a digital system using time division multiple access (TDMA) technique for communication purpose. A GSM digitizes and reduces the data, then sends it down through a channel with two different streams of client data, each in its own particular time slot. The digital system has an ability to carry 64 kbps to 120 Mbps of data rates. Features of GSM Module:  Improved spectrum efficiency  International roaming  Compatibility with integrated services digital network (ISDN)  Support for new services.  SIM phonebook management  Fixed dialing number (FDN)  Real time clock with alarm management  High-quality speech  Uses encryption to make phone calls more secure  Short message service (SMS) The security strategies standardized for the GSM system make it the most secure telecommunications standard currently accessible. Although the confidentiality of a call and secrecy of the GSM subscriber is just ensured on the radio channel, this is a major step in achieving end-to- end security.

GSM Modem A GSM modem is a device which can be either a mobile phone or a modem device which can be used to make a computer or any other processor communicate over a network. A GSM modem requires a SIM card to be operated and operates over a network range subscribed by the network operator. It can be connected to a computer through serial, USB or Bluetooth connection.

Working of GSM Module: From the below circuit, a GSM modem duly interfaced to the MC through the level shifter IC Max232. The SIM card mounted GSM modem upon receiving digit command by SMS from any cell phone send that data to the MC through serial communication. While the program is executed, the GSM modem receives command ‘STOP’ to develop an output at the MC, the contact point of which are used to disable the ignition switch. The command so sent by the user is based on an intimation received by him through the GSM modem ‘ALERT’ a programmed message only if the input is driven low. The complete operation is displayed over 16×2 LCD display

GPS

What is GPS? GPS or Global Positioning System is a satellite navigation system that furnishes location and time information in all climate conditions to the user. GPS is used for navigation in planes, ships, cars and trucks also. The system gives critical abilities to military and civilian users around the globe. GPS provides continuous real time, 3dimensional positioning, navigation and timing worldwide.

How does GPS System Work? The GPS system consists of three segments: 1) The space segment: the GPS satellites

GPS is used on some incidents in several ways, such as: 1. To determine position locations; for example, you need to radio a helicopter pilot the coordinates of your position location so the pilot can pick you up.

2. To navigate from one location to another; for example, you need to travel from a lookout to the fire perimeter. 3. To create digitized maps; for example, you are assigned to plot the fire perimeter and hot spots. 4. To determine distance between two different points. 3 Advantages of GPS: 

GPS satellite based navigation system is an important tool for military, civil and commercial users  Vehicle tracking systems GPS-based navigation systems can provide us with turn by turn directions  Very high speed 2 Disadvantages of GPS: GPS satellite signals are too weak when compared to phone signals, so it doesn’t work as well indoors, underwater, under trees, etc.  The highest accuracy requires line-of-sight from the receiver to the satellite, this is why GPS doesn’t work very well in an urban environment. Using a GPS Receiver: 

There are several different models and types of GPS receivers. While working with a GPS receiver it is important to have :       

A compass and a map. A downloaded GPS cable. Some extra batteries. Knowledge about the memory capacity of the GPS receiver to prevent loss of data, decrease in accuracy of data, or other problems. An external antenna whenever possible, especially under tree canopy, in canyons, or while driving. A set up GPS receiver according to incident or agency standard regulation; coordinate system. Notes that describe what you are saving in the receiver.

POWER SUPPLY: When working with electronics, you always need one basic thing: Power. In every electronic circuit power supply is required. The proper working of each and every component, the exact amount of voltage and current to be supplied to it. If the power exceed its limit, it can be fatal. Below is the circuit diagram of power supply which gives output of 5V, as only that much is required for microcontroller. Its circuit diagram and designing calculation are given below.

Fig.2.3 +5 V Regulated Power Supply The +5 volt power supply is based on the commercial 7805 voltage regulator IC. This IC contains all the circuitry needed two accept any input voltage from 8 to 18 volts and produce a steady +5 volt output, accurate to within 5% (0.25 volt). It also contains current-limiting circuitry and thermal overload protection, so that the IC won't be damaged in case of excessive load current; it will reduce its output voltage instead. The advantage of a bridge rectifier is you don’t need a centre tap on the secondary of the transformer. A further but significant advantage is that the ripple frequency

at the output is twice the line frequency(i.e. 50Hz) and makes filtering somewhat easier. The use of capacitor c1, c2, c3 and c4 is to make signal ripple free. The two capacitor used before the regulator is to make ac signal ripple free and then later which we are using is for safety, if incase there is a ripple left after regulating, then c3 and c4 will remove it. HARDWARE IMPLEMENTATION 3.1 Circuit Design Specification:3.1.1Power Supply Component Design: 1. Transformer Design:

Fig.3.1 Transformer Design We require 5V at the o/p of the regulator. The drop out voltage of the regulator is 2V As per the data sheet) Vdc = 5+2 = 7V So at the regulator input, the voltage applied should be of 7V. According to the formula, Vdc = 2Vm/Pi Assuming there is no ripple Capacitor from Vm= Vdc .pi/2 =7 x 3.14)/2

=10.99V Vm= 10.99V During one cycle, two diodes are conducting Drop out voltage of one diode = 0.7V Drop out voltage of two diode = 1.4V Vim = Vm+ 1.4V =10.99+1.4= 12.39V Vim=12.39V Vrms = Vim/sqrt(2) = 12.39/sqrt(2) = 8.76V Vrms = 8.76V So we select transformer of 9V. Similarly Im=Idc x pi/2 Im=400m x 3.14/2 = 628mA. Irms= Im/sqrt(2) = 628mA/sqrt(2) `

= 444.06mA Irms = 444.06mA

So we select the transformer of current rating 500mA. Considering the above transformer rating , We take the transformer of 0-9V/500mA TRANFORMER – 0-9V/500mA Stepdown transformer. 2. Rectifier Design: PIV of diode = Vm = 12.39V

Im= 628mA BRIDGE RECTIFIER -So, we select the bridge IC of 1Ampere rating. 3. Filter Capacitor Design:

Fig.3.2 Filter Capacitor Design R = Vdc/Idc = 7 / 400m = 17.5Ohms. Vr = 2(Vim – Vdc) = 2(12.39 – 7) = 10.78V C = Vdc/ (FxRxVr) = 7/ (100x17.5x10.78) = 371.05uF So for Safe working we select capacitor of 1000uF C = 1000uF / 35V C1= 1000uF/35V Electrolytic Capacitor. C2,C4 = 0.1uF Ceramic Capacitor. C3 = 220uF/25V Electrolytic Capacitor. So the power supply made from the above mentioned components gives the output of 5V.

For master PCB we are taking supply from USB. Through USB we get 5V, 500mA supply. This is given to AVR and LM317. Using LM 317 we can get 3.3 V outputs which are given to RF module. For the slave side we are using 9V battery. The output of battery is 9V DC is given to 7805 which is given to AVR controller. The output of 7805 is further given to the LM317 which gives 3.3V output which is given to RF module.

Software Development Dip Trace Dip Trace is an EDA/CAD software for creating schematic diagrams and printed circuit boards. The developers provide a multi-lingual interface and tutorials (currently available in English and 21 other languages). Dip Trace has 4 modules: schematic capture editor, PCB layout editor with built-in shape-baseauto router and 3D-preview & export, component editor, and pattern editor. An operating system (OS) is software that manages computer hardwareand softwarere sources and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, though the application code is

usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers. The dominant desktop operating system is Microsoft Windows with a market share of around 82.74%. mac OS by Apple Inc. is in second place (13.23%), and the varieties of Linux are collectively in third place (1.57%).In the mobile (smartphone and tablet combined) sector, use in 2017 is up to 70% of Google's Android ands according to third quarter 2016 data, Android on smart phones is dominant with 87.5 percent and a growth rate 10.3 percent per year, followed by Apple's iOS with 12.1 percent and a per year decrease in market share of 5.2 percent, while other operating systems amount to just 0.3 percent. Linux distributions are dominant in the server and supercomputing sectors. Other specialized classes of operating systems, such as embedded and real-time systems, exist for many applications. 3.5.2. Arduino C language Arduino is the hardware platform used to teach the C programming language as Arduino boards are available worldwide and contain the popular AVR microcontrollers from Atmel. Atmel Studio is used as the development environment for writing C programs for AVR microcontrollers
