矿井有限空间WIFI信号测评系统研究

Research of mine limited space WIFI signal evaluation system

针对矿井有限空间WIFI信号覆盖和工程验收困难,传统分段测评方法存在数据不兼容、测试效率低等问题,设计一种由嵌入式WIFI模块和无线网卡组成的矿井有限空间WIFI信号专用测评系统,嵌入式WIFI模块用于完成信号覆盖测试和干扰测试,无线网卡用于完成WIFI网络性能测试;在便携式终端使用CSharp语言编程对测试数据进行处理、存储、图形化显示,并结合矿井无线通信标准生成评估报告.研究结果表明:该系统能准确、客观、高效地反映矿井有限空间WIFI信号质量。

Aiming at current problem of mine limited space WIFI signal, which includes difficulty for sig- nal coverage and project acceptance, incompatible data and low efficiency resulted by traditional measure method, this paper designs a special mine WIFI signal test and evaluation system consisted of embedded WIFI module and wireless network card. The former is used to accomplish the test of signal coverage and interference, and the latter to measure network performance. By programming with CSharp language on portable terminal, it can process, store and display the test data, as well as generate assessment report combined with mine wireless communication standards. The research result indicates this system can re- flect quality of mine limited space WIFI signal accurately, objectively and efficiently.
