The Research Of Bluetooth-based Data Collection System On Bus

Bluetooth as a new short-range wireless communications technology standards, it is a low-cost, short distance, low-power wireless communication standard, and provides a wireless connection, and in vehicles on the application of electronic devices more wide. The paper based on the Bluetooth technology on the current bus automatic toll collection machine study.This paper introduce the origin of Bluetooth technology, features and development prospects of a brief introduction. And then analyze the Bluetooth communications system and the application of the framework agreement, and demand for the project, proposed a reasonable solution, and from both hardware and software, Bluetooth modules on the design of the elaborate. On the hardware design, detailed the selection of chips, modules and the design of the external interface design and expand the use of and understand the Bluetooth module ROK101 007 and the characteristics of the basic vehicle structure, analysis of the current automotive automatic toll collection Methods of data collection problems, on the basis of this, based on Bluetooth technology to the automotive machine wireless data transmission programme. In software design, the HCI (host control interface) to conduct a comprehensive analysis, is based on the RS232 interfaces and point-to-point transmission of the communication process. After detailed analysis of the current bus fares for automatic data collection methods existing problems, and to design a Bluetooth-based automatic toll collection machine wireless automatic data collection methods and the new programme, which is a reliable, safe, fast data Acquisition methods.
