【摘要】：将无线通信网络技术引入智慧医疗、智慧家庭等前沿的智慧城市技术领域,设计并实现了一种支持多监测点自由接入的无线便携式生物电信号智能监测与显示系统。提出了一种异步缓存机制,降低系统运算复杂度及开销,解决实时监测数据与现有无线网络接入问题;改进无线网络数据传输点协调控制(PCF)机制,提出优先级轮询及动态调整重发上限等技术手段,提高无线网络的通信效率,保证多用户情况下的实时监测与波形显示稳定性。通过NS2仿真及系统整体实测,表明设计能够达到连续不间断的无线监测与视频显示效果,与现有采用DCF和PCF网络机制相比,传输延迟降低5%和1%,且接入的设备数量越多优势越体现。该设计大幅改善设备使用灵活性与实用性,突破现有设备因体积及有线连接等方式只能局限于医疗机构等场地使用的限制,适用于智慧城市对智能健康监护的多用户、可移动、无线化、远程诊断与记录发展需求。
[Abstract]:Wireless communication network technology will be introduced into the intelligent medical, intelligent family and other cutting-edge smart city technology. A wireless portable intelligent monitoring and display system for bioelectrical signals is designed and implemented, which supports free access of multiple monitoring points. An asynchronous buffer mechanism is proposed to reduce the computational complexity and overhead of the system. Solve the problem of real-time monitoring data and existing wireless network access; The communication efficiency of wireless network is improved by improving the PCF mechanism of wireless network data transmission point coordination, putting forward the technical means of priority polling and dynamic adjusting the upper limit of retransmission. The stability of real-time monitoring and waveform display under multi-user condition is guaranteed. Through NS2 simulation and the whole measurement of the system, it is shown that the design can achieve continuous wireless monitoring and video display effect. Compared with the existing DCF and PCF network mechanism, the transmission delay is reduced by 5% and 1, and the more devices are accessed, the more advantages. This design greatly improves the flexibility and practicability of the device. Break through the existing equipment because of the volume and wired connection can only be limited to medical institutions and other sites to use restrictions, suitable for intelligent city to intelligent health monitoring multi-user, mobile, wireless. Remote diagnosis and documentation development requirements.
