【摘要】 随着高速增长的移动数据业务需求,无线网络的建设逐渐向着高带宽、高效率和低成本的方向进行发展,在无线局域网的大规模部署中,无线接入路由器的重要性变得越来越突出。为了提高无线接入路由器的产品质量,需要对设备进行不同方面的测试,分析测试结果并对设备进行改进。但是由于当前无线设备生产商对于无线接入路由器的测试主要集中在相对封闭且环境干净的实验室中进行,与设备的真实使用场景差距较大,导致在测试过程中所获取到的数据参考性不强。为了提高测试的精确度与可靠性,减少与实际使用环境的差别,为无线接入路由器功能和性能的改善提供有效的测试数据,本论文分析了无线接入路由器测试系统的需求,设计并实现了基于场景还原的无线路由器测试系统。通过对真实环境中存在的无线信号进行采集与传输,并在实验室中进行还原,从而实现在真实环境下对无线接入路由器的测试。本论文的主要工作归纳如下:(1)提出了基于场景还原的无线接入路由器测试系统的设计方案。通过对系统的需求进行分析,进而对系统作出总体设计,确立了系统的架构、功能模块划分、工作流程以及数据库表结构。(2)提出了无线信号采集、回传以及还原的处理方法。通过对无线接入路由器的软件程序进行修改,利用其作为信号采集器完成无线信号的采集,并将采集到的数据传送至实验室的服务器端,采用三角形定位算法完成采集信号的定位分析,依据定位分析结果将采集到的无线信号进行位置还原,并利用信号发生器发射对应强度、频率的信号,实现场景还原。(3)根据无线接入路由器的测试需求,分别面向单一设备测试和组网环境测试编写测试用例库和测试脚本,能够对其进行功能和性能方面的测试。(4)对实现测试系统的关键技术和方法进行了论述,并从场景的还原以及调用测试用例库中的测试用例对无线接入路由器进行测试这两个方面对测试系统的功能进行了验证。更多还原

【Abstract】 With the rapid growth of mobile data service demands,the construction of wireless network is developing gradually towards a direction of high bandwidth,high efficiency and low cost.The importance of wireless access routers has become increasingly prominent in the large-scale deployment of wireless local area network(WLAN).Therefore,to improve the quality of the wireless router,various tests have been conducted to the device and improvements have been made after a careful analysis of the tests’ results.However,most of the tests carried out by the manufactures are conducted in a closed clean laboratory environment,which is greatly different from the actual application scenario,and as a result of which,the test results become less credible for reference.In order to improve the accuracy and reliability of the tests,reduce the scene differences between the tests and the actual environment and to collect effective test data for product performance improvement,this thesis analyzes the requirements of a wireless router test system,proposes and realizes a design of wireless router test system that is based on scene restoration.By collecting and transmitting the wireless signals in the real environment,this test system can provide a laboratory environment that is the same with the actual application environment and conduct related wireless products tests.The main work is as follows:(1)Proposes a design scheme of wireless router test system based on scene restoration.The paper analyzes the demands of the system first,and then proposes an overall design of the system by establishing the system structure,functional modules,workflows and the structure of the database table.(2)Proposes methods of wireless signal acquisition,backhaul and restoration in the test system.The methods mainly are:modifying the bottom program of the wireless router and making it the signal acquisition device to collect wireless signals and transmit them to the server;using triangle localization algorithm to position and analyze the signals collected;according positioning results,restoring the position of the wireless signals collected and realizing scene restoration in the laboratoryby making use of the signal projectors to emit signals with corresponding strength and frequencies.(3)Compiles test case library and test scriptsfor both single device and network environment test according to their specific requirements for wireless access router,which is to test the functions and performance of the device.(4)Gives a detailed description of the implementation of several key points of the testing system.Tests and verifies the functions of the system from the aspects of scene restoration and calling test cases from the test case library.更多还原
