Electric signal parameter real-time monitoring system for engineering environment in construction operation process of electronic engineer

The invention discloses a real-time monitoring system for electric signal parameters of an engineering environment in the construction operation process of an electronic engineer. A filter circuit filters electric signals needing to be measured in the construction environment; the electric signals entering the front-end proportion circuit are amplified or reduced through an amplifying circuit or an adding circuit, and the electric signals after filtering processing are controlled to be 300 mv to 3.3 V; the electric signal amplified or reduced by the front-end proportional circuit enters an electric signal detection circuit, and resistance and current detection is carried out on the electric signal through the electric signal detection circuit; the electric signals detected by the electric signal detection circuit are sent to the single-chip microcomputer, the single-chip microcomputer detects the voltage of the electric signals, oscillogram drawing is carried out according to resistance, voltage and current v
