摘要: 针对因吊车等机械施工造成输电线路外力破坏的问题,提出基于射频雷达的输电线路预警联控系统,构建输电线路下的三维多级警戒区,通过计算目标RCS值、距离、速度、经纬度,进行空间分割、聚类、动静分离、跟踪等过滤识别处理,实现了输电线路下超高机械的状态监测、跟踪及预警。研发的吊车配备自主联动、监测及锁止装置,具备激光光幕定向警示及语音提示功能。现场试验结果表明,系统能有效防范输电线路外力破坏事件,可对吊车等超高机械入侵危险源提前预警、主动干预。

Abstract: Aiming at the issue of external damage to transmission lines caused by the construction of cranes and other machinery, a transmission line early warning and interlocking control system based on radio frequency radar is proposed to construct a three-dimensional multi-level warning zone under the transmission lines. Through calculations of target RCS value, distance, speed,longitude and latitude, spatial segmentation, clustering, dynamic and static separation, tracking and other filtering and recognition processing are carried out, which realizes the state monitoring,tracking and early warning of ultra-high machinery under transmission lines. The developed crane is equipped with autonomous linkage, monitoring and locking devices and has laser light curtain directional warning and voice prompt functions. On-site testing results show, the system can effectively prevent external damage to transmission lines and can provide early warning and active intervention for the intrusion hazards of ultra-high machinery such as cranes.

Key words: transmission line, radio frequency radar, three dimensional multi-level alert zone, laser light curtain, early warning, interlocking control
