Measuring device and measuring method for three-dimensional displacement of GIS busbar chamber relative to ground

Abstract

The invention provides a measuring device for the three-dimensional displacement of a GIS busbar chamber relative to the ground, which comprises an image processing unit and a marker, and is characterized in that the image processing unit is fixed on a busbar chamber, and the marker is fixed right below the image processing unit; the image processing unit comprises a camera, a storage unit, a calculation unit and a communication unit, the camera is used for imaging the marker and outputting an image of the marker to the storage unit to store; the calculation unit is used for acquiring three-dimensional displacement information of the busbar chamber according to central position variations of the marker in the imaged image and variations in the distance between two features points on the marker; and the communication unit is used for transmitting the three-dimensional displacement information, which is calculated by the calculation unit, of the busbar chamber to a monitoring center. The invention further provides a measuring method for the three-dimensional displacement of the GIS busbar chamber relative to the ground. The measuring device provided by the invention can measure the three-dimensional displacement of the GIS busbar chamber relative to the ground accurately, is simple in mechanical structure, low in installation requirement, low in cost and easy to be deployed in great quantities, and can be widely applied to the field of electric power monitoring.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for a three-dimensional displacement of a GIS bus compartment to the ground, in particular to a measuring device and a measuring method for measuring the three-dimensional displacement of a GIS bus compartment to the ground by using a sign and a single camera. Background technique [0002] The busbar cabin is one of the important components of the substation. It is found in actual operation that the GIS busbar cabin installed outdoors will be displaced and deformed due to the change of the ambient temperature. At present, there is no special equipment for monitoring this change. The first accident occurred due to the displacement and deformation of the GIS bus cabin. At present, there is no device capable of measuring the three-dimensional displacement of the GIS bus compartment. Generally, it can only measure the axial displacement. If the scale is generally used for observation on the...

Problems solved by technology

At present, there is no device capable of measuring the three-dimensional displacement of the GIS bus compartment. Generally, it can only measure the axial displacement. If the scale is generally used for observation on the spot, the measurement accuracy itself is not high. At the same time, due to random errors caused by human factors, the measurement results refer to For another example, the published paper "Tubular Busbar Displacement Monitoring System Based on Laser Ranging" proposed the method of using laser to measure displacement. After actual tests, there are big problems. It has high requirements, and is not suitable for outdoor online deployment. Its expensive price is not suitable for large-scale deployment. The measurement method uses the triangle principle. If there is a slight angle deviation during the installation process, the triangle principle will amplify the deviation and affect the measurement accuracy. Therefore, its practical application value is not great
