Bluetooth Vehicle Traveling Data Recorder

A Vehicle Traveling Data Recorder can be used to record and store the information of vehicles, such as velocity, time, distance, etc. It can also display and print the data stored. The Vehicle Traveling Data Recorder reminds drivers of safe drive, and it is of great importance in ensuring the safety of the vehicle traveling. It bases on the RS232 and USB for record transmission, it isn't convenient for application. Bluetooth technology is a world-wide open standard for wireless data communication. It fulfills the wireless connection for mobile device in short distance upon low cost. It realizes the wireless net among digital devices. It is widely used in communications, network, chip, software, communication wiring and car-making.This thesis bases on the status and characteristic of the vehicle traveling data recorder, brings forward a Bluetooth wireless technology vehicle traveling data recorder. Use the Bluetooth technology for the record transmission, it becomes simply and convenient, improves security and reliability. The system includes a Vehicle Traveling Data Recorder, a Bluetooth Data- Collecting Device and a computer installing Data-Analysis Software. First of all, the author introduces the brief description of the system structure, the characteristic of Bluetooth technology and its application. Second, the author bases the layout and the target vehicle acceleration data collection and analysis, choose the acceleration sensor, discusses the Vehicle Traveling Data Recorder including the hardware and the software, the design of Bluetooth peer to peer wireless interconnected. Then are described the design of the Data-Collecting Device and the Data-Analysis Software. The paper ends with a sum-up of the research work and a further conception of the system.
