摘　　要：由于心电图波形数据在计算机网络中传输对实时性和可靠性的要求都比较高,而目前网络传输层中常用的TCP协议和UDP协议均不能满足此要求。针对这种情况,提出一种对UDP协议进行改进的方法。通过对UDP协议的通信特点的分析,设计了一种实现简单、效率高的分包和拼接方法,添加了失序、包丢失和超时处理机制。实验结果表明,心电图波形数据利用改进后的UDP协议进行传输,可以满足其数据传输的要求。Since ECG waveform data has higher requirements on real-time property and reliability when transmitting in Internet, while neither the TCP protocol nor the UDP protocol commonly used in current networks transmission layer can meet these requirements. In view of this, we propose a method to improve UDP protocol. Through analysing the communication features of UDP protocol, we design a subcontracting and stitching method which is simple in implementation and high in efficiency, in it the processing mechanisms of disorder, packet loss and timeout are added. Experimental results show that the transmission of ECG waveform data can take the advantage of the improved UDP protocol to meet its requirements.
