Description

technical field [0001] The invention belongs to the technical field of high-performance and intelligent instruments, and in particular relates to a transmission ratio characteristic detection system and method of an automatic darkening welding filter. Background technique [0002] During welding operations, a large amount of ultraviolet rays, infrared rays, and strong light will be generated to damage the eyes. Therefore, people have developed automatic darkening welding filters to protect welders. The automatic darkening welding filter is composed of a photodetector, a light valve, a control circuit, a power supply, a frame, and inner and outer protection sheets, etc., and automatically controls the shading signal conversion of the filter through the initiation and extinguishment of arc light to realize the light and dark state conversion. Thereby effectively improving the protection of workers and work efficiency. [0003] According to the national standard GB / T3609.2-20...
