无线射频识别技术在地下管线标识和定位中的应用分析

Application and Analysis of Radio Frequency Identification Technology in Identification and Location for Underground Pipelines

大量的非金属管线应用于通信、给排水、热气等场所,其查找和定位工作无法顺利开展,无线射频技术有着寿命长、抗干扰性好、易于辨识的特点,为使其能在地下管线标识和定位中得以应用,介绍了无线射频设别技术的系统方案、射频供电机理以及阅读器和应答器的设计,比较了探地雷达、管线仪和无线射频识别器的优缺点,提出了在识别器在施工时的注意事项,对其在地下的应用作了应用分析和展望。

In view of a large number of non-metal pipeline applied in communications, water supply and drainage, gas and other places, which make the work of finding and locating can not be carried out smoothly, and the wireless radio frequency identification technology has characteristics such as a long service life, good anti-jamming features and easy to identify. In order to make it can be used in the identification and location for underground pipelines, introduced the system scheme, radio frequency identification technology and radio frequency power supply mechanism of the reader and transponder design, compared the advantages and disadvantages of the radar, pipeline locator and radio frequency identifier, also mentioned the matters needing attention in the construction of the recognizer, put forward the application analysis and prospect to make it can be applied in the underground.
