Bluetooth Applications

BLUETOOTH APPLICATION plagiarise In the current scenario the world is plagued by accidents which ar primarily due to humane errors in judgment and hence thousands of lives be lost. These accidents mountain be avoided if only in that respect was a mechanism to alert the number one wood of approaching danger. This can be make by proctoring the surpass between nearby auto quicks and alerting the thingamajig driver whenever the distance be fathers as well as short. This is precisely the aim of this musical composition.In this paper we propose the wasting disease of Bluetooth Technology by which we can check the speed of the cable railway auto whenever it come ups dangerously snug to any an separatewise(prenominal) fomite up front, thereby thriftiness real many lives.

REFERENCES INTRODUCTION Since Bluetooth devices argon capable of communication with eight other devices simultaneously we can monitor and check the speeds of up to eight cable motor elevator cars simultaneously, thus preventing accidents.Thus if we have dickens Bluetooth enabled devices in cardinal cars the devices automatically communicate with severally other when they come in the vomit up of up to 100 meters of to apiece(prenominal) one other. The align is dependant on the power clear up of the product. Power transmission rates turn in many Bluetooth devices depending upon the power deliverance features available in a crabby unit, bandwidth requirements, transmission distance. The statistics of road accidents is tremendous and highlights the posit for such a arrangement. The fol baseing is a statistic on the number of road accidents occurring each year.ROAD ACCIDENT STATISTICS OF INDIA 1970-2003 Sl. No. Source info received from States/UTs. s OPERATION Because of change of location at high speeds there is a ca lamity of having accident. The figure 2 shows that when two cars or more(prenominal) come deep smoothen the distance of 10 km at high speeds there is a possibility of having accidents. The Bluetooth radio is a short distance, low power radio operating in the unlicensed spectrum of 2. GHz and using a nominal antenna power of 20 dBm. pic At the 20 dB the range is 100 meters, meaning equipment must be Within 100 meters to each other ( around 328 feet) to communicate using the Bluetooth standard. With the help of this engineering we can send data to the eight devices. The group of eight devices is known as piconet. Here we have a piconet and a scatternet, in the piconet M is the outmatch and S1 to S7 are the slaves pic Radio communication is subjected to noise and interference, as the 2. 4 GHz frequencies are divided up between the all device in piconet.So the Bluetooth specification has solved this problem by employing what is called as spectrum spreading, in which the Bluetooth ra dio hops among different frequencies very quickly. There are 79 hops starting at 2. 402 GHz and stopping at 2. 480 GHz, each of which is displaced by 1 MHz. The Bluetooth avoids interference by hoping around these 79 frequencies 1600 times per plump for. So in order to avoid it we use bluetooth equipped car, in which each car have bluetooth transmitter and receiver. And the either car should have mini electronic computer to monitor the relative position of the car with the other car. picWhen any car comes close in concert bluetooth device sends warning designate to the car. base on the type of warning guide received the computer sends presageing to the bracken control clay to slow down the speed of the car. There are two types of control signs. First type of signal control the speed of the car and the second type of signal is to overtake the car which is moving forward. Schematic diagram of car pic AUTOMTIC BRAKE SYSTEM The automatic pasture brake system is the next gene ration braking system for controlling the speed of the car.On receiving the control signal from the traveling car the computer internal the car manipulates the signal and gives control signal to the braking system. There are four primary(prenominal) components to an automatic braking system speed sensors watch valves controller pic Automatic braking pump and valves The computer constantly monitors the distance between each of these cars and when it senses that the car is jack offting too close it moves the hydraulic valves to increase the pinch on the braking circuit, effectively increasing the braking force on the wheels.If the distance between two vehicle is within the 100m the Bluetooth devices get enabled and if the distance come closer within 10m the automatic braking system takes the control. After the speed of the car is rock-bottom and distance increased the hydraulic valves drops the pressure on the braking circuit, thus effectively decrease the braking force on t he wheels. The following locomote show the versatile functions of the hydraulic valves in position one, the valve is open pressure from the headwaiter cylinder is passed right through to the brake. in position two, the valve blocks the line, isolating that brake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder. in position three, the valve releases some of the pressure from the brake.REPRESENTATION OF OUR IDEA In the figure 7 when car A and car B come within the range of 100m both the Bluetooth devices get enabled and if any one of the car comes too fast then the bluetooth device sends a warning signal to the other car and it processes the signal and gives it to the automatic braking system. pic CONCLUSION The Bluetooth engineering is being widely adopted by the Industry leaders. The possibility for new applications is very exciting with this Versatile technology. It provides a simple, licit answer to all th e Problems-which is built a single common radio into every mobile computer, then neither do companies have to worry about WAN, nor do communication companies need to worry about building external cables. The Bluetooth communication device will thus be a small, low powered radio in a chip that will rag to other Bluetooth enabled products.Bluetooth has been designed to solve a number of connectivity problems experienced by the mobile workers & consumers. Thus, this technology helps make the electronic devices more user friendly and helps address various other problems like accidents. digit 1 gondola 1 CAR 6 CAR 4 CAR 3 CAR 7 CAR 8 CAR 5 CAR 2 MINI COMPUTER INSIDE THE CAR Fig 2 M S72222222 S1 M2 S2 S1 M1/S S1 S1/S3 M1 S3 Fig 3 Fig 4 Fig 5 Fig 6 Within 10m Sends warning signal Receives signal and control the speed of car Fig 7
