自动路测系统中智能数据采集终端设计

Design of Intelligent Data Collection Terminal in System of Automatic Drive Test

传统的无线通信网络数据采集终端,存在着数据反馈不实时,难以进行多网络测试同步对比,人力物力资源浪费等问题。为解决这一问题,文中设计了一种基于ARM的智能数据采集终端,该终端包括数据采集模块、传输模块、GPS定位模块以及自适应电源模块。该设计中电源模块供电之后,传输模块会自主下载测试任务,数据采集模块会根据测试任务智能地进行相应的语音或者数据业务数据采集工作,同时传输模块会将采集到的数据相对实时地回传数据中心。本设计通过对语音和数据业务场景的重现,最大程度地实现了无人值守的网络质量数据的高效采集。

The traditional data collection terminal of a wireless communication network exists many problems, such as data feedback with- out real-time performance, difficulties of carrying out multi-network testing simultaneous contrast and waste of human and material re- sources. To solve these problems, in this paper, an ARM-based data collection terminal has been proposed, including data acquisition module,transmission module, GPS positioning module and adaptive power module. In this design, after powered by the adaptive power module, the transmission module will download the test tasks autonomously and the data acquisition module will intelligently implement relative data collection on voice or data services. Meanwhile, collected data will be sent back to data center relatively without time-delay by the transmission module. By reproducing scenes of voice and data services, the design realized efficient collection for unattended network quality data.
