摘　　要：本文提出了一种基于TETRA数字集群通信系统实现图像摄取传输的实现方案,分析了图像传输功能中的传输协议,大文件传输,丢包,乱序以及图像传输的完备性检测等关键技术,并给出了具体解决方法。通过对移动电台终端、移动设备和调度终端等设备的分组数据连接配置,编程实现了利用数字集群系统进行图像摄取传输的功能,扩充了集群系统的业务范围。This article presented an implementation proposal, which could achieve and transfer the image files between mobile devices and PC based on Terrestrial Trunked Radio （TETRA） Digital Trunked Communication System. The key technologies and solutions of the image transmission, such as transmission protocol, large files transmission, packet loss, disorder packets＇ sequence and the completeness testing, were proposed. By packing the data connection configuration for mobile radio terminals, mobile equipment, as well as dispatching terminals, the image transmission feature based on digital trunked system was implemented, which expanded the business scope of the trunked system.
