Study On Vehicular Safety Monitor System Based On Bluetooth

Automobile is a kind of important vehicle. Despite its convenience and advantages nowadays in our life, it also brings a lot of social problems, among which traffic accident is very typical. Traffic accident, to some extent, always causes economic loss and harm to people. In a car accident, the automobile's condition, as well as the driver's instant reaction, plays a very crucial role in the liability attribution.This article proposes a vehicle-carried wireless monitor system, based on the combination of embedded-control technology, Bluetooth wireless transfer system and information security technology. This system records the image data during driving, especially those right before accidents, and other situational statistics about the vehicle condition. Then, it steps further to secure the statistics through data encryption and digital signature. Under the security process, statistics is stored in flash in case of use afterwards, and can provide important evidence for liability cognizance.This system is basically made up of Information Collection Cell (Front) and Centre Control & Data Safely Disposing and Cell (Back). Its statistical communications is done by means of wireless Bluetooth. Besides, the mark of statistics combines time and space information offered by GPS, meanwhile, the initial design of soft and hardware model is secured through the Bluetooth and its affiliated information and secure technology. The experimental test was done under the statistical Bluetooth transfer and encrypted signature.This thesis focuses on introduction of embedded technology, including its characteristics, the way and its application in vehicular condition. The systematical model structure and its working theory are also studied in it. Besides, it specially introduces the basic norms of wireless Bluetooth technology, and analyzes according to the HCI of Bluetooth plus the control command of its interface and the data disposing for safety.The vehicular wireless monitor system in this thesis offers applicable...
