Measuring instrument for power transmission line tower
2016
The invention provides a measuring instrument for a power transmission line tower, and belongs to the field of electric power equipment. The measuring instrument comprises an equipment bearing base, a stepping motor is arranged on the equipment bearing base, a laser transmitter is fixed to the edge of the equipment bearing base, and a laser receiving sensor, a camera and a processing circuit are further arranged on the equipment bearing base. When the stepping motor rotates, the camera acquires the video of light spots formed by laser irradiating to a target object and acquires frame images of the light spots in the video, the distance between the power transmission line tower and an ambient target object is determined according to the distance between the power transmission line tower and the target object and angular speed, an ambient environment distance diagram taking the power transmission line tower as a center is drawn according to the distance, the influence of sunlight on the distance can be effectively avoided, and laser ranging accuracy is improved.
