The invention discloses an informatization remote monitoring system based on big data. The informatization remote monitoring system comprises a smoothing input circuit, a rectified feedback circuit and a voltage stabilizing output circuit. According to the smoothing input circuit, an inductor L1, a capacitor C1 and a capacitor C2 are used for forming pi-type circuit smoothing, then signals are input into the rectified feedback circuit, according to the rectified feedback circuit, an amplifying circuit composed of a triode Q1 and a triode Q2 is used for conducting differential amplification onthe signals, meanwhile, a rectifying circuit composed of an operational amplifier AR1, an operational amplifier AR2, a variable resistor R15 and a capacitor C3 is used for rectifying the signals, meanwhile, a triode Q3 and a triode Q5 are used for feeding back and correcting the potential of output signals of the rectifying circuit, a triode Q4 is used for conducting positive feedback on an emitting electrode signal of the triode Q2, and finally the voltage stabilizing output circuit applies a voltage stabilizing circuit composed of a triode Q6, a triode Q7 and a voltage stabilizing tube D4 toconduct outputting after voltage stabilization, so that signals in a signal transmission channel are used for automatically and effectively correcting data signals received by the informatization remote monitoring system based on the big data, and signal turbulence is prevented.
