Intelligent monitoring equipment for monitoring fault of video camera

Abstract

The invention discloses intelligent monitoring equipment for monitoring a fault of a video camera. The intelligent monitoring equipment comprises an operational amplifier input circuit, an enhanced calibration circuit and a clamp output circuit, wherein the operational amplifier input circuit receives a data signal output by a modulation signal module in the intelligent monitoring equipment for monitoring the fault of the video camera; the enhanced calibration circuit utilizes a triode Q2, a triode Q3, a triode Q4 and a triode Q5 to form a signal enhancement circuit for enhancing signals; an operational amplifier AR3 and a variable resistor RW1 form a frequency modulation circuit for modulating frequency of signals; an operational amplifier AR2 is designed for feeding back signals to an emitter of the triode Q2, so as to adjust output signal potential of the frequency modulation circuit; and finally, the clamp output circuit utilizes a diode D2 and a diode D3 to clamp an output signalof the enhanced calibration circuit to be in a range from 0 to +5 V, and the signal is filtered for output by means of a pi type filtering circuit composed of an inductor L3, a capacitor C4 and a capacitor C5. The intelligent monitoring equipment realizes automatic calibration of the signals, stabilizes the signal frequency and potential, and prevents signal distortion.

Problems solved by technology

[0004] In addition, in the actual application of this kind of equipment, when the signal output by the modulating signal module passes through the 4G signal sending module, the signal is often out of tune and the frequency is unstable, which leads to distortion of the signal received by the 4G signal receiving module.
