家庭、社区远程医疗诊断系统数据传输协议的设计

The Design of Data Transfer Protocol for Home and Community Tele-medical System

南方医科大学基础医学院生物信息学研究室,广州,510515针对社区和家庭远程医疗诊断服务系统的需要,设计了一种医学生理信息存储格式和传输协议。该协议以ASCII字符为基础,以帧为基本结构,分为控制指令帧和数据帧两种。控制指令帧可实现启动、结束传输,确认指令,请求启动等功能。数据帧根据传输数据的不同分为7种,完成数据传输的功能。该协议简洁明了,可扩展性强,在实际的系统中完成了预定目标的应用。

This article describes a design of physiological signal storage format and transfer protocol for the tele-medical system between home and community. The protocol is based on ASCII character with frames as itsbasic structure. There are two kinds of frames： control frames and data frames. Control frames can start and stop data transfer, confirm the order, and ask for start. There are seven kinds of data frames, according to the different data types. Data is transferred in data frames. The protocol described in this article is simple and extensible. The design target has been accomplished in real system.
