基于 FTPS的实时图像传输软件的设计与实现

摘要

We design a real-time image transmission software targeted at the problem of mainstream FTP software that its functions cannot be customised and it cannot meet the special requirement of image data transmission.The software of real-time image transmitter ( RIT) is based on FTPS protocol, and is designed and developed with C#language.The client of RIT includes the timing image search module, the image compression and transmission management module, and the image transmission module.The server of RIT includes the timing search module and the decompression module, they jointly accomplish the functions of physical transmission of real-time image from client to SSL-basedfile server, automatic rechecking and transmission records storage, etc.As a data transmitting module for hospital pathology informationsystem, RIT plays an important role on the backup and sharing of massive image information.Experimental results show that the method achieves good effect in real-time images transmission and management, and is feasible in application of engineering.%针对主流FTP软件功能无法定制，不能满足影像数据传输特有的需求，设计了实时图像传输软件。实时图像传输器RIT （ Real-time Image Transmitter）软件基于FTPS协议，利用C＃语言设计并开发。 RIT客户端包括定时图像检索、图像压缩与发送管理、图像发送等模块；服务器端包括定时检索与解压模块；共同完成实时图像从客户端到SSL型服务器端的物理传输、自动查重及发送记录存储等功能。 RIT作为医院病理信息系统的数据传输模块，在海量图像信息的备份与共享上发挥了重要作用。实验结果表明RIT应用在实时图像传输与管理上可以达到较好的效果，在工程上应用是可行的。
