Abstract

The invention discloses an intelligent water affair data aggregation terminal. The circuit comprises a signal receiving circuit, a delay feedback circuit and an operational amplifier output circuit. The signal receiving circuit receives signals demodulated by the water affair data control terminal to stabilize voltage stabilization by using voltage-regulator tube D1, the delay feedback circuit forms an average circuit by using an operational amplifier AR1, a diode D2, a diode D3 and a capacitor C2; extraction of mean signals, one path of an output signal of the operational amplifier AR1 buffers the signal by using a buffer circuit consisting of a diode D4, a triode Q2 and a capacitor C3; in the second path, a triode Q5 and a capacitor C4 are used to form a time-delay circuit time-delay signal; finally, the two paths of signals are input into a frequency modulation circuit composed of a triode Q3, a triode Q6 and resistors R8-R10 to adjust the signal frequency. A triode Q7 and a triodeQ8 are used to form a push-pull circuit to prevent signal distortion, an operational amplifier output circuit uses an operational amplifier AR2 to amplify signals in the same phase and then outputs the signals, and the problem that the instantaneous transmission throughput of the signals is too large is solved.

Description

technical field [0001] The invention relates to the technical field of data aggregation, in particular to an intelligent water data aggregation terminal. Background technique [0002] At present, the intelligent water affairs data gathering terminal mainly includes a control terminal, a data acquisition module, a signal transmission module, and a display module. The terminal demodulates the signal and analyzes the signal, controls the display module to display the data information of the intelligent water pipe network, and the control terminal is a data aggregation terminal. When the control terminal or the signal transmission module fails, when it is repaired again, the information received by the control terminal instantly The throughput will be much greater than the normal throughput, which will cause the control terminal to receive signal disorder and seriously affect the operation status of the intelligent water data aggregation terminal.
