摘要
目的:研制基于蓝牙技术适用于医疗设备间的无线数据通讯与控制系统。方法:系统根据蓝牙主控制器(HCI)接口规范,采用双微控制器模式,通过HCIRS-232物理接口连接蓝牙模块,实现医疗设备之间数据通讯。电源采用串口窃电技术为系统供电。结果:该系统在10m的范围内能实现良好的数据和文件传输,误码率在10-6以下,串口通讯速率可达38.4kb/s。结论:该系统具有稳定性高,体积和质量小等特点,基本能满足实际工作需要。
Objective To develop a wireless data communication and controlling system between medical devices based on bluetooth technology. Methods According with Bluetooth host controller interface（HCI） specification, the system adopted double micro-controller mode, and was connected with Bluetooth module through the HCI RS-232 physical interface, to realize data communication between medical devices. A serial port was used as the power supply. Results The System could realize data and file transmission within 10 meters, with a bit error rate less than 10-6 and a serial communication speed up to 38.4 kbit/s. Conclusion The high stability, small volume and light weight make the system meet the requirements in practice.[Chinese Medical Equipment Journal, 201 O, 31 （2） ： 28-31 ]
