Embodiment 1

[0015] Embodiment 1, a big data-based power grid security management information system, the weak signal in the big data transmission channel of the power grid received by the noise suppression circuit is composed of capacitor C1, capacitor C2, inductor L1, inductor L2, inductor L3, and capacitor C3 Band-pass filter (specifically, a high-pass filter circuit composed of capacitor C1, capacitor C2, and inductor L1 is connected in series with a low-pass filter circuit composed of inductor L2, inductor L3, and capacitor C3 to form a band-pass filter) to filter out different frequency interference and improve the immunity Interference ability, after the transient suppression diode VD1 suppresses the electromagnetic interference transmission to the subsequent stage, the peak pulse release circuit composed of resistor R1, capacitor C4-C6, thyristor VTL1, and voltage regulator Z1 eliminates the peak pulse interference in the same frequency signal, and then enters The low-noise amplifie...

Embodiment 2

[0016] Embodiment 2, on the basis of Embodiment 1, the low-noise amplifier circuit receives the weak signal output by the noise suppression circuit, and only allows the frequency component of the received signal to pass through the band-pass filter of the capacitor C7 and the inductor L4, blocking the frequency components other than the frequency. After avoiding other frequency signal interference, it enters the input terminal of the amplifier composed of transistor Q1 cascaded field effect transistor T1, and performs two-stage low-noise amplification (because when amplifying weak signals, the noise of the amplifier itself interferes very much with the signal Seriously, in order to take into account low noise generation and high gain amplification, the characteristics of the input impedance and output impedance of the triode Q1 and field effect transistor T1 are used to cascade to form a low-noise amplifier), and then the emitter follower of the triode Q2 reduces the output impe...

Embodiment 3

[0017]Embodiment 3, on the basis of Embodiment 2, the weak signal in the large data transmission channel of the power grid received by the noise suppression circuit passes through the band composed of capacitor C1, capacitor C2, inductor L1, inductor L2, inductor L3, and capacitor C3. The high-pass filter circuit composed of capacitor C1, capacitor C2, and inductor L1 is connected in series with the low-pass filter circuit composed of inductor L2, inductor L3, and capacitor C3 to form a band-pass filter, which only allows large data from the power grid. The frequency component of the weak signal in the transmission channel passes through, preventing other frequency components from passing through, adjusting any inductance and capacitance value can adjust the range of frequency components allowed to pass through, filtering out interference signals, improving anti-interference ability, and then through the transient suppression diode VD1 suppresses the transmission of electromagn...

Abstract

The invention discloses a grid security management information system based on big data. A noise suppression circuit receives a weak signal in a big data transmission channel of the grid. A band-passfilter filters out inter-frequency interference. A transient suppression diode VD1 suppresses electromagnetic interference. A spike release circuit eliminates spike interference in the same frequencysignal and the weak signal enters a low noise amplifier circuit. The low noise amplifier circuit uses a triode Q1 cascaded FET T1 for two-stage low-noise amplification, and a triode Q2 emitter to follow the output. The low noise amplifier circuit uses an operational amplifier AR4 feedback emitter to follow the output signal to the input of the transistor Q1 and ensure that the signal after low noise amplification meets the requirements for the signal amplitude. Finally, the feedback regulator circuit is used, and a pass transistor Q3 is combined with the feedback regulator circuit of a photocoupler U1 to output a stably varying 0-5V signal to the server of the grid security management information system based on the big data. According to the grid security management information system based on the big data, the problem that the signal cannot be effectively received by the server since the signal distortion and the attenuation in the network information transmission channel is solved.
