CAN Bus Network Design Based on Bluetooth Technology

The integration between Bluetooth technology and the field bus is an important item in the industry field application of the wireless communication. By the analysis of Bluetooth technology and the field bus network topology architecture, we put over the interconnect topology architecture based on Bluetooth wireless sensor network and CAN bus, also finish the system hardware design and software development that contains three components: CAN intelligent controller and CAN-Bluetooth intelligent master nodes based on the MCU8051 and Bluetooth sensor nodes based on MCU2051. We mainly resolved Bluetooth technology protocol and CAN bus protocol and realized the conversion between them. Experiments indicated that the system could operate reliably and steadily and CAN-Bluetooth nodes could deliver the data correctly transmitted from the Bluetooth wireless sensor nodes in real time to the upper computer to process through CAN bus intelligent controller.
