摘　　要：针对现有井下通信设备不成体系,通用性不强的问题,提出一种基于LwIP协议的应用层通信协议,并基于该应用层协议设计一种以ARM芯片为核心的数字多媒体通信系统.首先介绍系统使用的硬件设备,然后展示软件功能和上位机软件,其中详细阐述基于LwIP协议栈的应用层设计思路,最后设计试验进行系统测试.经试验测试表明:所提出的应用层协议可以达到设计的功能和性能要求;同时,所设计的系统与现有的通信设备在功能上相比,升级对讲功能为实时通话功能,增加视频传输功能和上位机控制,增强了实用性且更方便统一管理.Aiming at the problem that the existing downhole communication equipment is not systematic and universal,this paper proposes an application layer communication protocol based on LwIP protocol,and designs a digital multimedia communication system based on this application layer protocol with ARM chip as the core.First of all,the hardware equipment used in the system is introduced,then shows the software functions and the upper computer software,which elaborates the application layer design ideas based on the LwIP protocol stack,and finally designs experiments for system testing.The experimental test shows that the application layer protocol proposed in this paper can meet the designed functional and performance requirements,and at the same time,the system designed in this paper upgrades the intercom function to real-time call function,increases the video transmission function and the upper computer control compared with the existing communication equipment in terms of function,which enhances the practicality and is more convenient for unified management.
