Study and Literature Survey for Wireless Data Acquisition for Automobile Dashboard

Abstract: The collection of the real time data before moving the vehicle i.e immediately after Starting the vehicle to drive the driver can see the status or the health of the various parts of the vehicle which is determined or analyzed by the data collected at the moment and simultaneously transmitting the data over the wireless network. The data acquisition System (DAQ) is used to collect the data like speed, engine temperature, Brake status, fuel sensor, tyre pressure, acceleration, GPS position, wiper movement, and time etc. This data can be used to see that whether the vehicle is safe for the ride or should go for the service. The data collected by DAQ is used by the service person to come to know the problems in the vehicle which reduces the time taken to analyze the problem as it points at the problem associated area. If required the data can be collected using a SD card for analyzing purpose. The main purpose of this paper is to avoid accidents rather than alerting police after the accident .In system data is collected by using different sensors and wireless communication. the DAQ system is implemented over FPGA SoC.

INTRODUCTION he major problem in many countries is to control vehicle accidents. Due to some factors like speed driving, drunk driving, riding without sufficient sleep, etcall cause to increase the number of accidents.The numbers of death and disability are very high because of late assistance by public to the person who met with the accident. Due to this maximum automobile manufacturers are developing safety devices to protect riders from accidents. However, a perfect safety device for vehicles is difficult to implement and it will cost more. On roads, drivers usually a maintain distance from one vehicle to another. On the other hand ,due to lots of interruption, like longtime driving, sudden application of brake by the car which is ahead, even though the driver is in a conscious mind he cannot respond immediately to control vehicle. Sometimes crash may occur due to bad weather. Like if rain has started and wipers are not working then it can lead to poor visibility of the road due to which accidents can occur.so if we have devised a system which can tell the status before starting the drive so that we can overcome this situation.
