摘要
现有技术电缆定位检测依托金属探测器与图纸结合方法,由于受城市地层地基钢筋、管网影响,金属探测器难以准确探测,导致电缆实际位置定位不准,外破事故频发的痛点难以根治,极大影响了电缆供电可靠性。射频识别(RFID)技术只能标记大概位置,无法精确描述具体电缆信息,对于电缆故障征兆或故障后的定位也不具备预警或检测能力。提出了一种新型双芯片地下电缆定位标签,可以较为精确地实现地下电缆定位。
The existing technology of cable positioning detection relies on the combination of metal detectors and drawings.Due to the influence of steel bars and pipe networks on the urban ground,it is difficult for metal detectors to detect accurately,resulting in inaccurate positioning of the cable and difficult to solve the frequent external breaking accidents,which greatly affects the reliability of cable power supply.Radio frequency identification(RFID)technology can only mark the general position rather than accurately describe the specific cable information,and has no warning or detection ability for cable failure symptom or location after failure.A new type of dual-chip underground cable positioning tag is proposed to accurately locate underground cable.
