Household video monitoring system

Abstract

The invention discloses a household video monitoring system. The system comprises a frequency acquisition circuit 1, a frequency acquisition circuit 2, a rectification calibration circuit and a filtering output circuit. The frequency acquisition circuit 1 and the frequency acquisition circuit 2 respectively acquire analog signals at the input end and the output end of a signal transmission channelin a control terminal of the household video monitoring system. The rectification calibration circuit uses a variable resistor RW1, a capacitor C4, and a capacitor C3 to form a rectifying circuit torectify the signal, and uses a diode D6-diode D9 and an amplifier AR1 to form a composite circuit for signal limiting, amplification, and limiting processing. The frequency acquisition circuit 2 usesthe op amp AR2-AR4 and the capacitor C14 to form a loss compensation circuit to compensate the output signal of the rectification and calibration circuit. Finally, the filter output circuit uses the inductor L2, the capacitor C10, and the capacitor C11 to form a [pi]-type filter circuit. The filtered output can convert the signal frequency into a compensation signal of the signal at the output endof the signal transmission channel in the control terminal of the home video monitoring system.
