Aiming at requirement of catenaries routine inspection in electrified railway maintenance work area
develops a portable laser measuring instrument which is used to test catenaries geometry parameters.Combining the method for catenaries geometry parameters measurement
builds an effective measuring model.It uses DSP2812 as the master chip and completes design of hardware circuit such as laser sensor
angle measurement sensor
video camera and so on
and also completes software design of laser measuring instrument.Verifies the correctness of design of the measuring instrument through experiment.
