Abstract :
Interference can affect the stability of system and accuracy of test results; even damage the components or system. Thus, anti-interference techniques are necessary for modern test system. Focused on a Lumber Stress Rating System we developed, a set of anti-interference designs to restrain the influences of different disturbance factors on system were conducted. These interferences including electric power, transmission channels, electromagnetic radiation, etc. Results obtained in the investigation confirm that every measure can have better effects as new anti-interference method is applied; as well as linear power has better anti-interference effect than switching power. The final result indicates that the measurement of using linear power while adding low-pass filter and isolation transformer, with effective grounding measure has the best anti-interference effect.
