蓝牙锁的研究与开发

蓝牙技术实现了小型的移动设备之间的无线连接，这样在设备之间传递数据就不需要线缆了。蓝牙设备工作在2．4GHz的工业、科学与医学频上，这一频段不需申请就可使用。蓝牙射频部分的设计能提供设备间快速，稳定，安全的连接。跳频技术使得在传送与接收数据包时可以避免其它信号的干扰。蓝牙锁是北京邮电大学与有关单位合作的国家863科研项目，用于实时监测装有要害数据电子设备如数据库装置，各种信息安全控制设备的工作状态是否正常，是否被人移动，攻击等。目前该产品已经申请了国家专利。

Research and Development of Bluetooth Lock

Bluetooth wireless technology is a specification designed to enable wireless communication between small,mobile devices.In this case there is no need for cables to transfer data between devices. The radio of bluetooth devices operates in the 2 4 GHz Industrial,Scientific,and Medical(ISM)band which is globally available.The Bluetooth Radio is designed to operate in a noisy radio environment and to provide a fast,robust,and secure connection between devices.Stability is ensured by implementing a frequency hopping scheme which enables Bluetooth Radio modules to avoid interference from other signals after transmitting or receiving a data packet.Bluetooth lock belongs to the 863 scientific research project carried on by BUPT and relative units.It is used to inspect that if important electronic devices such as database equipment and information security control facilities are working well,moved or attacked.At present,bluetooth lock has applied for the state patent.
