摘　　要：近年来,家庭医疗监护系统对无线数据传输的可靠性、实时性以及便捷性提出了更高要求。系统是基于蓝牙HID规范的家庭医疗监护仪,利用BLUELAB4.01开发环境和它的底层协议栈库,建立了蓝牙芯片和主控芯片之间的命令包和数据包,使得可低时延和可靠地实现传感器数据传输、键盘输入等功能。文章着重介绍了蓝牙模块的功能实现,讨论了低延迟以及延长电池寿命的方法。实验结果总结了不同呼吸间隔下的实际电流消耗。The recent family health care system requires high-reliability, low-latency and flexibility for wireless transmitting. Here we present a family health care system based on the Bluetooth HID profile technology. With the help of strong BLUELAB4.01 development environment and its low-layer stack library, we established a communication protocol and related data packets between the Bluetooth module and the Host IC to realize the fast and reliable data transmitting from sensor or keyboard to the Host.In the article, we deeply discussed the realization of Bluetooth functions, and how to achieve the balance of low-latency and long power life. The experiment results concluded the actual currency cost with the different sniff interval parameters.
