摘要
蓝牙技术是一种开放的无线短距互联技术。蓝牙模块可通过基于IEEE 1451.2标准和基于通用异步接发模式(UART)与智能传感器接口构成无线传感器网络。蓝牙无线传感器网络结构分为原始信息收集的下层、原始数据预处理的中间层、和负责数据处理的上位机等3层。比较IEEE 1451.2和UART,基于蓝牙技术的无线智能传感器网络采用UART模式。其系统软件包括上位机应用程序、嵌入智能传感器模块的MCU程序、蓝牙模块HCI固件程序,及上位机、MCU与HCI间的通讯程序。硬件由爱立信ROK 101 007蓝牙模块,和以ADuC812为核心的智能传感器模块构成。
Bluetooth technology is an open short-range wireless interlinkage technology. Bluetooth module can be connected with the intelligent sensors to form a wireless intelligent sensor network via an interface of IEEE 1451.2 or UART. The bluetooth intelligent sensor network consists of three layers of lower layer collecting original information, middle layer pretreating original data, up layer processing data. Comparing IEEE 1451.2 with UART interface, the sensor network uses UART interface to intergrate bluetooth module with intelligent sensor. The system software includes application program in PC, the MCU program in of embedded intelligent sensor module, HCI firmware of bluetooth module and communication program among PC, MCU and HCI. The hardware consists of Ericsson bluetooth module ROK 101 007 and the intelligent sensor module based on ADuC812.
