When angular displacement sensor can measure the angle change of main shaft, be thus finally inversed by contact net height change；Contactless contact
Net height measurement apparatus mainly uses optical principle to measure, usually accurate using one end alignment contact net transmitting of device
Collimated optical beam, the detector of the device other end receives the reflected beams, and then branch office's light beam is drawn in the projected position of detector target surface
The height of contact net.In actual production because contact measuring apparatus can only measure contact net height indirectly, it is impossible to directly for by
Pantograph directly provides the feedback information of contact net height, thus using it is relatively broad be that contactless contact net elevation carrection is filled
Put.But because train speed is high in practical application, Contact Line Detection information is big, and single lidar measurement can not meet inspection
The requirement of real-time of survey, so being badly in need of being improved to lift detection real-time to contact net detection means.
