Remote monitoring system and method for ice coating process of power transmission lines

Abstract

The invention discloses a remote monitoring system and method for ice coating process of power transmission lines and belongs to the field of power industry monitoring system products. The remote monitoring system includes a simulation wire, a tension sensor connected with the simulation wire, a binocular camera and a control box; a data acquisition module connected with the binocular camera, a control module connected with the tension sensor, a communication module connected with a central control terminal and the like are arranged in the control box; the remote monitoring method is a method for obtaining three-dimensional geometric information of an object from multiple images based on the principle of parallax, wherein two digital images of the measured object can be obtained simultaneously by the binocular camera from different angles, the three-dimensional geometric information of the object is restored based on the principle of parallax, the three-dimensional profile and position of the object are reconstructed, and the three-dimensional image data is transmitted to the central control terminal for calculation, so as to master the dynamic changes of ice coating in real time. According to the invention, the ice coating data monitoring accuracy and convenience can be satisfied, the expansibility is excellent, and the data monitoring sensitivity is improved.

Description

technical field [0001] The invention relates to a remote monitoring system and method for the icing process of transmission lines, belonging to the field of monitoring system products in the electric power industry. Background technique [0002] In 2013, according to the requirements of the State Grid Corporation of China, municipal bureaus installed artificial ice viewers at key ice monitoring points to measure ice. However, due to the bad weather during the ice-covering period, and the ice-observing areas are generally located in areas that are difficult for personnel to reach, the previous artificial ice-observing methods need to consume a lot of manpower, and in extremely bad weather, personnel cannot reach the observation point for measurement. In addition, due to the irregularity of the ice coating, the thickness and shape of the ice coating cannot be accurately measured by manual measurement. The low installation position of the artificial ice viewer is inconsistent ...

Problems solved by technology

However, after the line is icing, the comprehensive load of the conductor changes, and several common monitoring methods cannot reflect the icing condition of the line very well, and have limited guiding significance for actual production work.
