摘要:
报道一种基于网络自协商信号检测网络线缆故障位置、类型及阻抗失配的新方法,利用网络系统中的自协商信号替代传统反射测量法中的外部信号,通过相关运算实现网络线缆故障测量.以RG-S2828G交换机的自协商信号为例,实验测量非屏蔽双绞线不同长度的断点距离,其定位的相对标准偏差为0.29%. 此方法可同时测量阻抗失配情况,实现故障类型判断,为网络故障检测提供新思路.
Abstract:
A new method of detecting the location, type and impedance mismatching of the network cable fault based on the auto-negotiation signal is presented in this paper. Replacing the external signal of the traditional reflectometry with the auto-negotiation signal in the network system, the detection of network fault breakpoints is realized by the correlation method. Different fault points of the unshielded twisted pair are located experimentally by utilizing the auto-negotiation signal of RG-S2628G switch, and the relative standard deviation of fault location is determined to be 0.29%. The experiment results also show that the value and location of impedance mismatching and the fault type can be determined. Our method provides a new idea for network fault detection.
