摘　　要：为保证特高压输电塔实时监测系统数据传输的可靠性、安全性,针对常用的无线传输信道GPRS网络的自身缺陷以及系统所处的特殊环境,提出了在应用层设计相应的系统性能优化方案,采用应答确认机制以及自适应重传机制提高了数据传输的可靠性,应用分段嵌入签名机制以及随机动态认证机制保障数据传输的完整性并及时发现受第三方攻击的连接。实验结果表明,改进后数据传输的性能得到较大的优化。In order to guarantee the data transmission reliability and safety of UHV transmission tower real-time monitoring system, this paper proposes that a system performance optimization scheme be designed in the application layer, given the deficiencies of the conventional GPRS network and the particular condition around the system. The response confirmation mechanism and the adaptive retransmission mechanism are utilized to improve the data transmission reliability; the application of the subsection insertion signature mechanism and random dynamic authentication mechanism can ensure the integrity of the data transmission and detect the connection which is attacked by hacker in time. The experimental results show that the data transmission performance gets a greater optimization after improvement.
