Embodiment 1

[0013] Embodiment 1, the intelligent terminal system of integrated real estate payment and certificate issuance equipment includes an anti-interference circuit, a signal amplitude adjustment circuit and a hysteresis voltage stabilization circuit. The signal transmitted by the equipment suppresses electromagnetic interference through the transient suppression diode VD1, the RC absorption circuit composed of the resistor RT1 and the capacitor C1 further absorbs the electromagnetic interference and releases it to the ground, and the frequency selection composed of the variable capacitor CY, the capacitor C2 and the inductor L1 After the circuit screens out the single frequency signal in the signal, it enters the signal amplitude adjustment circuit. The signal amplitude adjustment circuit first uses the operational amplifier AR1 as the core amplifier to perform proportional amplification, and then enters the operational amplifier AR2 and operational amplifier AR3 as the core window ...

Embodiment 2

[0015]Embodiment 2. On the basis of Embodiment 1, the anti-interference circuit receives the signal transmitted from the real estate payment and certification integrated equipment intelligent terminal system, and first suppresses electromagnetic interference through the transient suppression diode VD1. Then enter the RC absorption circuit composed of resistor RT1 and capacitor C1 to further absorb electromagnetic interference and release it to the ground, so as to avoid the problem that the signal at the input end of the signal transmission channel is interfered by external signals during signal transmission, and finally through the variable capacitor CY and capacitor C2 And the frequency selection circuit composed of inductor L1 screens out the single frequency signal of the signal at the input end of the signal transmission channel and transmits it backwards, so that other frequency signals are blocked, including transient suppression diode VD1, resistor RT1, resistor R1, tran...

Embodiment 3

[0016] Embodiment 3, on the basis of Embodiment 1, the hysteresis voltage regulator circuit is used to trigger the triode Q1 to be turned on when the window circuit outputs a low level, and the proportionally amplified signal passes through the π circuit composed of capacitor C3, capacitor C4, and inductor L2. Type filter circuit filtering, and then through the hysteresis comparator composed of operational amplifier AR4, resistors R8~R10, potentiometer RP1 capacitor C5, and voltage regulator tube Z2 to eliminate the slight voltage change near the signal amplitude after proportional amplification (the size of the voltage is determined by the resistor R8 , potentiometer RP1, capacitor C5, and voltage regulator tube Z2 provide a voltage divider circuit, adjust the potentiometer RP1 to adjust the size of the tiny voltage), improve the anti-interference ability, and then input the stable voltage into the intelligent terminal system of the real estate payment and certification integra...

Abstract

The present invention discloses a real estate payment and certificate integrated device intelligent terminal device. An anti-jamming circuit performs inhibition, electromagnetic interference absorption and frequency selection of receiving signals, the receiving signals are transmitted into a signal amplitude regulation circuit, an operational amplifier AR1 is taken as a core amplifier for scale amplification, a window circuit is employed to detect whether the amplitudes of the signals are abnormal or not, when the signal amplitude is abnormal, difference value signals are added to a transmitting electrode of an unijunction transistor Q1, a conduction angle of the unijunction transistor Q1 is changed to change signals coupled to the input end of the operational amplifier AR1 to regulate thesignal amplitude, when the signal amplitude is normal, the signals are transmitted to a delaying voltage stabilizing circuit, the signals after scale amplification are processed by a filter circuit and a hysteresis comparator to eliminate tiny voltage change near the signal amplitude values after the scale amplification of the signals so as to input the stable voltage into a control terminal signal transmission channel in a real estate payment and certificate integrated device intelligent system after improving the antijamming capability and effectively solve the technical problems that the attenuation, the anti-jamming and the stability of signal transmission are poor in the data safety intelligent operation and maintenance monitoring system.
