Automatic darkening filter with adaptive parameter adjustment and working method thereof

An automatic darkening filter with adaptive parameter adjustment, comprising:

• a welding arc intensity detection unit configured to provide a first signal for determining a 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 an ambient light intensity;
• and
• a CPU (central processing unit) 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 a scale number of the light valve based on the difference,
• wherein the solar power supply module comprises:
• a solar panel configured to generate electricity through the ambient light, and generate a varying voltage signal as the second signal based on changes in the ambient light;
• and
• a first analog-to-digital (ADC) converter configured to acquire the second signal and convert the second signal into a second digital signal, and transmit the second digital signal to the CPU.
