摘要
目的:研制一种用于监测水下作业潜水员实时心率参数的便携式装置。方法:硬件系统设计为2个部分,包括心率检测单元和心率接收单元。心率检测单元位于潜水服之内,心率接收单元位于潜水服之外,2个单元之间采用无线通讯方式,心率接收单元与船上计算机之间采用有线的485传输方式,可进行长距离传输。结果:样机完成后经过反复测试,基本达到设计要求,成功实现陆上心率实时传输和水下模拟心率信号实时传输功能。无线传输模块水下可靠传输的最大距离可达10 m,且无线信号的传输距离和深度、压力无关。结论:硬件装置改进耐压和防水性能后,完全可以实现潜水员水下心电、心率信号的实时监测,并可扩展到其他生理信号的实时监测。
Objective To research a portable device which can monitor the real-time heart rate（HR） for underwater diver.Methods Hardware system included two parts,HR detecting unit and HR receiving unit.The detecting unit was inside the divingde,while the receiving unit was outside the divingde.Wireless communication was adopted between these two units,and line communication was adopted between receiving unit and a computer on board.Results Repeated tests showed that the basic design requirements were attained.The distance of wireless communication between the above two units achieved to 10 meters,and was independent of depth and pressure.Conclusion After improving the capability of pressure and water resistance to the hard devices,ECG and HR monitoring for underwater diver can be fully realized.
