非接触式图像检测以其行车干扰小、通用性好、便于安装使用等优点在弓网综合检测车、定点弓网检测设备、移动式弓网检测设备及手持式弓网检测设备中获得越来越广泛的应用。在总结国内外近年来最新弓网检测设备研究的基础上,从弓网非接触式检测设备、弓网图像智能识别算法等方面出发,研究非接触式图像检测在弓网参数识别、弓网故障检测等方面的最新进展;分析现有弓网图像识别研究中的不足;针对弓网图像检测识别存在的问题提出一些可行思路;对弓网检测设备未来研究工作提出建议。
Non-contact image detection has been applied more and more widely in the pantograph-catenary com- prehensive inspection car, stationary pantograph-catenary inspection devices, mobile pantograph-catenary in- spection devices and hand-held pantograph-catenary detection devices owing to its advantages of few operating troubles, good generality and easy to installation. After summarizing the latest domestic and overseas develop ment of pantograph-catenary inspection devices,the non-contact inspection devices and intelligent image recognition algorithms were studied to look forward to the up-to-date progresses in the field of non-contact panto- graph-catenary parameter recognition and faults detection. The defects of the present pantograph-catenary image recognition system were analyzed and some ideas were proposed to solve the existing problems. Suggestions were made for future research work regarding pantograph-catenary inspection devices.
