Abstract
An automatic darkening filter with adaptive parameter adjustment includes: a welding arc intensity detection unit configured to provide a first signal for determining the welding arc intensity; a solar power supply module configured to provide electric energy for the welding arc intensity detection unit and provide a second signal for determining the ambient light intensity; and a CPU and a light valve, the CPU being configured to calculate a difference between the welding arc intensity and the ambient light intensity based on the first and second signals, and control the scale number of the light valve based on the difference. The automatic darkening filter can realize the automatic adjustment of the scale number, and in the adjustment process, the welding arc intensity signal can be revised based on the ambient light intensity, which can effectively ensure the accuracy of the final determination of the scale number.
