随着人工智能技术的广泛应用,将其引入光缆维护工作中,尤其是在故障的诊断和维护辅助决策等方面,可使光缆维护工作的效率得到有效提高。针对通信光缆故障点位置及故障类型判断困难,维护效率较低等问题,提出了一个基于地理信息系统GIS的故障智能决策方法,根据光时域反射仪OTDR的基本工作原理及其在光缆接续点测量中各种接续点衰减曲线的特征,设计了专家系统的相关知识规则,并且结合通信光缆维护的具体特点和要求,建立了一个光缆沿途区域的GIS系统,以实现通信光缆维护的信息化和智能化,提高了光缆维护工作的维护效率。
With the widespread application of artificial intelligence technology, it will be introduced into the optical cable maintenance work, especially in the fault diagnosis and maintenance of auxiliary decision-making, optical fiber cable maintenance work can be effectively improved. Aiming at the problems such as the location of the fault point of communication optical cable and the difficulty of judging the type of fault and the low maintenance efficiency, a fault intelligent decision-making method based on geographic information system (GIS) is proposed. According to the basic working principle of optical time domain reflectometer OTDR and its connection point The characteristics of decay curves of various connection points are measured and the relevant knowledge rules of the expert system are designed. Based on the specific characteristics and requirements of the maintenance of communication optical cable, a GIS system of the optical cable along the area is established to realize the informationization of communication optical cable maintenance Intelligent, improve the maintenance efficiency of fiber optic cable maintenance.
