Abstract

The invention discloses a differential amplification signal processing system for a sewage network monitoring device based on big data. The differential amplification signal processing system mainly consists of a processing chip U, a triode VT2, a polar capacitor C6, a polar capacitor C7, a differential amplification circuit, a second-order low-pass filter circuit, a frequency error correction circuit and a differential amplification circuit, wherein the frequency error correction circuit is connected with a CS pin, a G pin and an OUT pin of the processing chip U respectively; and the differential amplification circuit is connected in series between a CLK pin of the processing chip and the frequency error correction circuit. Through adoption of the differential amplification signal processing system, low-frequency interference signals in signals can be eliminated or restrained, and frequency points of signals subjected to anti-interference processing can be amplified, so that the signals are more stable. Moreover, phase and frequency errors of multicarrier signals in data signals can be corrected, so that the signal processing effect is improved, and the accuracy of sewage data information obtained by a data processing center is ensured effectively.
