摘要
针对现有有线语音视频传输系统敷设困难、作业移动性差,无线系统传输距离短、传输带宽小的情况,提出一种基于新型组网应用模式。通过搭建无线音视频传输样机系统,验证了组网方案的可行性,同时在应用过程中对组网工作方法进行了研讨。该系统基于IEEE 802.11 b/g,可以与TCP/IP协议转换,具有标准化、兼容性好、高带宽、多级无线中继的特点,适合于井下复杂环境传输音视频数据。
To counter the situations of difficult laying of the existing wire voice video transmission network,its poor oeprational mobility,the short tansmission distance and small transmission bandwidth of the wireless system,an application mode based on new network was put forward.The feasibilty of the wireless voice video transmission network scheme was verified by building its prototype system,and meatime,the working method of the wireless voice video transmission network was studied in its application process.This system is based on IEEE 802.11 b/g and can be converted with TCP/IP protocol,has the features of standardization,good compatibility,large bandwidth,and multi-stage wireless relay,and is suitable for the transmission of audio and video data in complex undreground environment.
