数据传输改进方案在医疗设备监测系统的应用

针对在医疗设备监测系统中，因网络拥塞和储存速度缓慢，造成的网络丢包现象，设计并实现了数据传输改进方案，该方案采用TCP拥塞控制和多线程双缓存算法。TCP拥塞控制通过动态队列管理算法，设定最大丢弃概率，对TCP连接请求进行管控。多线程双缓存算法通过双线程缓存队列对数据包完成储存。实验在45、55、65台设备同时发送数据时，数据包的接收成功率为100%、99.6%、99.1%，结果表明:数据传输改进方案能有效提升数据包的接收成功率。

Application of Improved Data Transmission Scheme in Medical Equipment Monitoring System

Aiming at the phenomenon of network induced packet losses caused by network congestion and slow storage speed in the research of medical equipment monitoring system， this paper designs and implements an improved data transmission scheme， which adopts transmission control protocol（TCP） Congestion Control and Multithreading Double-cache Algorithm. TCP Congestion Control manages the queue of TCP connection requests by setting the maximum discard probability which follows dynamic queue management algorithm. Multithreading Dual-cache Algorithm stores packets through the dual-thread cache queue. In the experiment， when 45， 55， 65 devices respectively send data at the same time， the success rates of receiving data packets are100%， 99.6%， 99.1%. The result shows that the improvement scheme of the data transmission can effectively improve the success rates of receiving data packet.
