Multi-channel communication synchronous transmission system

Abstract

The invention discloses a multi-channel communication synchronous transmission system. The system comprises a frequency acquisition module and a comparison feedback module, the frequency acquisition module uses a frequency collector J1 of which the model is SJ-ADC to acquire the carrier signal frequency of a multichannel communication node signal transmitter. The comparison feedback module uses anoperational amplifier AR1 and a triode Q4 to form a detection circuit to adjust a signal waveform. An operational amplifier AR2, a resistor R6 and a capacitor C4 form a comparison circuit for comparing output signals of a push-pull circuit and the detection circuit; a high-level detection circuit composed of a triode Q5 and a voltage stabilizing tube D5 is used for detecting an output signal of the operational amplifier AR2; an operational amplifier AR3 compares a transmitter signal of the triode Q5 with an output signal of a composite circuit; and the signal is sent to a controller of the multichannel communication synchronous transmission system through a signal transmitter E1, so that the carrier signal frequency of the multichannel communication node signal transmitter can be calibrated and converted into a correction trigger signal of the multichannel communication synchronous transmission system controller.

Description

technical field [0001] The invention relates to the technical field of communication transmission, in particular to a multi-channel communication synchronous transmission system. Background technique [0002] At present, communication transmission is a multi-channel communication transmission method, especially the information interaction is becoming more and more complicated, which requires multi-channel multi-node segmented transmission, or even multi-channel synchronous transmission, adapting to today's rapid development of information delivery, and at the same time the signal transmission requirements It is also getting higher and higher, and multi-channel synchronous transmission often causes noise accumulation, which reduces communication quality, and even clutter signals appear, resulting in signal distortion. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is ...
