<正> 蓝牙(Bluetooth)是一种低功率短距离的无线连接技术标准的代称,“蓝牙”一词取自一位在公元10世纪统一了丹麦的国王,哈拉德二世(Harald)的绰号,即蓝牙(Bluetooth)。蓝牙技术的最初倡导者是五家世界著名的计算机和通信公司:爱立信 Ericsson,国际商用机器(IBM),英特尔(Intel),诺基亚(Nokia)和东芝(Toshiba)。并于1998年5月成立了蓝牙特殊利益集团(BluetoothSpecial Interest Group-SIG),该组织采取了向产业界无偿转让该项专利技术的策略,以实现其全球统一标准的目标。 相似文献

An overview of the Bluetooth wireless technology 总被引:7,自引:0,他引:7
The BluetoothTM wireless technology is designed as a short-range connectivity solution for personal, portable, and handheld electronic devices. Since May 1998 the Bluetooth SIG has steered the development of the technology through the development of an open industry specification, including both protocols and application scenarios, and a qualification program designed to assure end-user value for Bluetooth products. This article highlights the Bluetooth wireless technology 相似文献

Bluetooth in wireless communication 总被引:3,自引:0,他引:3
Bluetooth is a method for data communication that uses short-range radio links to replace cables between computers and their connected units. Industry-wide Bluetooth promises very substantial benefits for wireless network operators, end workers, and content developers of exciting new applications. This article delves into the implementation and architecture of Bluetooth. It also describes the functional overview and applications of Bluetooth, and deals with the development of a model for recording, printing, monitoring, and controlling of eight process variables at the same time, using a distributed control system. We explain industrial automation via Bluetooth using IISS. Industrial automation is one of the major applications of Bluetooth technology. Industrial automation, in terms of controlling or monitoring a factory, office, or industrial process, means to install machines that can do the work instead of human workers. Industrial plants consists of many devices interconnected in different ways ranging from simple data collection units (I/O) to more intelligent devices such as sensors, one-loop controllers, or programmable controllers, and a supervisory system used as a human-machine interface (HMI) for data logging and supervisory control. An IISS is a controlling device that monitors the devices in a company. It basically communicates via the interface card in the PC; the hardware is connected parallel across the device, and it is interfaced with the PC via a transceiver. The device can be accessed both manually via the switches and remotely via the PC. A simulation of connecting a PC with the machines in a company was executed. Also, we wrote a software program using C language; we will show how the remote monitoring takes place between the control room and the PC. These details in the article establish the growing need for Bluetooth technology 相似文献
