摘要
基于在线监测装置、紫外光电传感器、便携式数据处理计算机等设备,设计了一套刚性接触网在线监测装置。通过光学检测法,利用模态匹配法进行图像识别,实现测量弓网振动位移、分析弓网受流情况以及燃弧检测的目的,并将该检测装置进行了实际应用。应用表明,该系统效果理想,可准确发现故障,为刚性接触网日常维护提供了一种有效的监测方式。
With a research of the online monitoring device,ultraviolet photoelectric sensor,portable data processing computer and other equipment,a set of online monitoring device for rigid contact network is designed.Then,through optical detection,the mode matching method is used to realize image recognition,measure the vibration displacement of pantograph and network,analyze the current situation of pantograph network and the goal of arc detection,in order to apply the device in practical detection.The application shows that the system is effective in detecting faults accurately,thus providing a useful way for routine maintenance of rigid catenary.
