| Abstract (English): | In order to adapt to the military requirement of modern war digitization and solve the problems of increasing amounts and types of information need to be transmitted in the battlefield environment and constrained network bandwidth, a decoding module of variable message format(VMF) is designed as the technical support of underlying message. Using dynamic link library, Java Script object notation(JSON),Snappy and other technology, it can provide the service of message codec for the upper application. The design is based on the template of JSON, bit stream integrated compression algorithm and the data dictionary structure JSON, and then realizes the message sent "on demand" and the combination of dynamic message content according to the different delivery requirements. The experiment shows that coding and decoding only takes about 3 ms in the designed module, while the original decoding system takes over 200 ms. Obviously, it can increase the rate, and further shorten the length of the encoded data stream. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): | 为适应现代战争数字化的军事需求,解决战场环境下需要传输的信息种类和数量日益增多 以及网络带宽受限等问题,设计了可变报文格式( VMF) 编解码模块,作为底层消息传送的技术支 撑。利用动态链接库、JSON(Java Script Object Notation)、Snappy(压缩算法) 等技术为上层应用提供 消息的编解码服务,设计基于JSON 的可变长报文模板、比特流集成压缩算法、基于JSON 的数据字 典结构,实现报文的“按需发送冶,根据不同的发送需求,动态地组合报文内容。实验显示所设计的 模块编码解码只需3 ms 左右,而参考系统编解码则需耗时200 ms 以上,可见速率提升明显,数据流 长度也进一步缩短。 [ABSTRACT FROM AUTHOR] |
