Description
Technical field
The present invention relates to transmitter field, is a kind of multipath analog signal summation transmitter.Power to D.C. high-current
System, more DC source parallel operations, to the analog voltage signal of every DC source DC current sensor collection always add
The analog signals output of demand is converted to, metering and technology controlling and process are examined for In situ DC electricity.Being widely used in Gong ﹑ have
The fields such as the electrolysis such as non-ferrous metal.
Background technology
It is traditional with the mark that social development is energy-saving and increases economic efficiency as social progress and development in science and technology
Large-scale electrolysis DC power supply system, operating current bring up to 60 present Wan An, 1 direct current of past from past several Wan An
Source power supply can not meet live electrical demand, it is necessary to which more DC power supply parallel operations could meet electrolysis process needed for scene
Electric current.More DC power supply parallel operation real-time current sizes must fast send electrolytic cell in real time, be electrolysed automatic process control
Processing procedure sequence adjusts operating procedure according to supplied size of current.Require to have the total plus conversion for being quickly added more unit electric currents for this
Device, always plus converter precision, response speed directly influence electrolysis automatic process control.Traditional software gathered data, which is added, to be needed
It will be changed into digital signal respectively per road analog signal, and adopt sample several times by the way that software is per second to be added the result so drawn inaccurate,
Response speed influences site technique operation slowly reduces electric effect.
The content of the invention
The invention aims to provide a kind of multipath analog signal summation transmitter.Input signal and output signal are not
Need to filter, isolation module is using analog signal into analog signal goes out to be not required to plus the module of any capacitance-resistance peripheral components ensures signal
Response speed.Two groups of working powers become the rectified bridging direct current of low pressure by transformer high-voltage and use three-terminal voltage-stabilizing offer positive and negative
Working power, avoids live high current high-intensity magnetic field adverse circumstances from influencing working power, it is ensured that output signal accuracy and stabilization.
The technical scheme is that：A kind of multipath analog signal summation transmitter, it is characterized in that multichannel analog signals connect
Differential adder is connect, differential adder connects isolation module, the differential adder of working power A connections and isolation module, isolation mode
Block connects zero suppression converting unit, zero suppression converting unit connection analog output signal A and analog output signal B, working power B connections
Isolation module, zero suppression converting unit, analog output signal A and analog output signal B.
Due to taking above-mentioned technical proposal, multicomputer direct current supply can be divided electric current to correspond to scaling signal addition and be converted to
Resultant signal, exportable plurality of voltages or current standard signal, shows for In situ DC electricity, measures examination and technology controlling and process, work
Make power supply, input signal, output signal three isolation avoid either signal and high voltage short circuit and damage other equipment.

Number A5 and analog output signal B6.
Multichannel analog signals 1 do add operation and ratio amplifier through differential adder 2, and differential adder 2 exports signal and passes
Isolation module 3, isolation module 3 is by signal isolation for the signal on ground does not give zero suppression converting unit altogether with differential 2 identical value of adder
4, signal zero suppression no-load voltage ratio is passed analog output signal A5 and analog output signal B6, analog output signal A5 by zero suppression converting unit 4
4 derived signals of zero suppression converting unit are changed into the analog voltage of standard respectively with analog output signal B6 or current signal exports.
Working power A7 is multichannel analog signals 1, differential adder 2, isolation module 3 provide working power, and working power B8 is isolation
Module 3, zero suppression converting unit 4, analog output signal A5, analog output signal B6 provide working power.
