Problems solved by technology

[0005] The three types of thermal imaging cameras can monitor the temperature conditions of substation equipment to varying degrees, but they all have certain disadvantages: handheld thermal imaging cameras can only be used for inspections, cannot monitor in real time, and require manual operation; The monitoring range of fixed thermal imaging cameras is limited; pan-tilt thermal imaging cameras can monitor and cover a larger area with the help of pan-tilt rotation function, but like fixed thermal imaging cameras, the infrared temperature analysis pictures they generate They are all two-dimensional, not visual and intuitive enough, and the equipment temperature monitoring area is also scattered without integrity, which makes it difficult for the maintenance personnel to grasp the overall temperature status of the equipment

Abstract

The invention relates to a 3D infrared temperature monitoring method and a system for a substation. The monitoring system comprises a bureau device data center, a substation device data center, thermal infrared imagers, high-accuracy holders and visible light cameras. The bureau device data center is connected with the substation device data center through networks, the substation device data center is connected with the thermal infrared imagers through a switcher by network cable interfaces, the substation device data center is connected with the high-accuracy holders through communication interfaces and connected with the visible light cameras through coaxial cables. The monitoring method comprises that infrared picture two-dimensional planar data obtained through the thermal infrared imagers are converted into 3D spatial data, 3D substation virtual scenes are generated through 3D modeling, and device models are subjected to corresponding body surface temperature color rendering. According to the 3D infrared temperature monitoring method and the system for the substation, thermal infrared imager temperature measurement is combined with substation 3D modeling, and accordingly, device temperature conditions can be displayed for 360 degrees in all directions and real time, and accuracy and effectiveness of monitoring are improved.

Description

technical field [0001] The invention belongs to a method and system for monitoring electric power equipment, in particular to a method and system for three-dimensional infrared temperature measurement and monitoring of substations. Background technique [0002] In the power system, temperature detection, as one of the most commonly used live detection methods, has been widely used in the condition-based maintenance of power equipment. With the promotion of on-line monitoring technology for substation equipment, infrared temperature on-line monitoring will be widely used in the condition maintenance of power equipment. [0003] Infrared imaging is the only diagnostic technique that can instantly visualize and verify thermal information. Thermal imaging cameras convert infrared radiation from surfaces that are invisible to the human eye into visible infrared images that reveal and quantify thermal faults through non-contact temperature measurement. [0004] At present, infra...
