Problems solved by technology

However, subject to various factors of technical strength, the current fault judgment is mostly focused on visual observation and empirical judgment, and the detection methods also stay in off-line detection methods such as multimeters and oscilloscopes. The efficiency is low, the effect is poor, the detection methods are backward, and the accuracy is not high. Low level of intelligence
