一种无线网络端到端时延检测方法

针对项目中对某无线网络双向通讯时端到端时延检测的需求，本文经深入研究，提出了一种利用 GPS 接收机进行时钟同步，基于道系统实时进程项目的多站点组网下端到端无线网络通讯时延检测方法。根据该方法，设计并实现了基于上位机、下位机方式的通讯检测系统。经多次测试采样，利用统计学理论给出了比较准确的时延检测结果。本文提出的方法从时钟同步、 操作系统选择、软件设计和结果分析方法等多方面充分考虑了其对检测结果的影响，采用精确、 实时、优良、合理的方法，提高了测试结果的准确度

End-to-End Time Delay Detection Method for Wireless Network

For the needs of the end-to-end time delay detection of a wireless network in two-way communication in the project, this paper has conducted in-depth research and proposed a GPS receiver for clock synchronization, multi-site networking, end-to-end Wireless network communication time delay detection method based on real-time process project which works on the Delta System. According to the method, a communication detection system based on upper computer and lower computer is designed and implemented. After many tests and samples, statistical theory was used to give more accurate data of delay detection results. The method proposed in this paper fully considers its impact on the test results from many aspects such as clock synchronization, operating system selection, and software design and result analysis methods. Accurate, real-time, excellent, and reasonable methods are used to improve the accuracy of test results.
