| Traditional catenary detection method requires installing the sensor on the pantograph.When the detection of catenary geometry parameters and dynamic characteristics was runningon the high-speed railway, we faced with poor experimental environment and the severevibration. If the traditional detection methods are used, the pantograph following performancewill be affected, and catenary test parameter errors will be larger than usual.This paper fully studies the detection technology development status and trends. A typeof non-contact detection method to contact wire height, dynamic stagger and other parametersis developed based on our existing catenary detection system’s theoretical basis.This non-contact method has no effect on the catenary system’s dynamic flow characteristics.The video data we used is got from the video camera included in original detection method.After the processing, we will get the contact line height and the pull-out value. |
