基于双频载波的电缆屏蔽层实时防盗监控系统设计

摘要

该文设计的电缆防盗监控系统应用了双频载波技术,既可以实现故障监控与定位,又可以实现三维GIS可视化管理.通过对电缆屏蔽层载波信号进行实时监测,可以及时发现电缆屏蔽层断线故障并通知维修人员紧急处理,减少电缆被盗损失,有效提升城市电网的安全水平.%In this paper,a cable antitheft monitoring system is designed,which use of the technology of dual-frequency carrier,it could be monitoring and locating the fault point as well as management with three-dimensional GIS visualization. It could be finding the break of cable shielded layer timely and no-tify maintenance personnel for emergency treatment by real time monitoring the carrier signal on cable shielded layer,and so that reduce losses with cable is stolen and promote the safety level of city power distribution network effectively.
