Highly-stable signal processing system for sewage discharging network monitoring device based on big data

Abstract

The invention discloses a highly-stable signal processing system for a sewage discharging network monitoring device based on big data. The highly-stable signal processing system is mainly formed by a processing chip U, a triode VT2, a polar capacitor C6, a polar capacitor C7, a signal bandwidth regulation circuit, a differential amplification circuit, a second-order lowpass filtering circuit, and a frequency error correcting circuit connected with a CS tube pin, a G tube pin and an OUT tube pin of the processing chip U. The differential amplification circuit is serially connected between a CLK tube pipe of the processing chip U and the frequency error correcting circuit. Low-frequency interference signals of the processing chip can be eliminated or prohibited; frequency point of the signal after anti-interference process can be amplified, so the signal can be more stable; phase positions of multi-carrier wave signals of data signals, and frequency errors can be corrected, so signal processing effect can be improved; and accuracy of sewage data information acquired from a data processing center can be effectively guaranteed.

Description

technical field [0001] The invention relates to a processing system, in particular to a high-stability signal processing system for a sewage network monitoring device based on big data. Background technique [0002] Today's society is a rapidly developing society, with advanced technology, information flow, people's communication is getting closer and closer, and life is becoming more and more convenient. Big data is the product of this high-tech era. Big data refers to a huge data set collected from many sources in multiple forms and has strong real-time characteristics. With the continuous development of information technology, big data is widely used in sewage network monitoring devices. The current sewage network monitoring device based on big data is mainly composed of a big data processing center, a monitoring point collection box, a regional signal transceiver system, a regional signal processing system, and a regional data storage system; and whether the sewage data...
