Description
Technical field
The utility model relates to a kind of multifunction electronic belt conveyer scale, belongs to the detection technique field.
Background technology
The material transportation is link important in the commercial production, generally need the flow of material be detected and control.Present belted electronic balance is mainly used to measure the flow by the material of belt, and function singleness need be equipped with control devices such as PLC and could form perfect autofeed control system.There is complex structure in this feed control system, and is with high costs, is unfavorable for applying.
Summary of the invention
The purpose of this utility model provides a kind of multifunction electronic belt conveyer scale simple in structure, to solve traditional belted electronic balance function singleness, need join the defective that the PLC controller could autofeed.
The utility model is realized by following technical scheme: a kind of multifunction electronic belt conveyer scale comprises belt conveyer scale main frame 1, LOAD CELLS 2, tachogenerator 3, frequency converter 4, oscillating feeder 5, belt 6; LOAD CELLS 2 is installed in belt 6 bottoms, gather the material gravitational cue, tachogenerator 3 contacts with belt 6, to gather the belt speed signal, LOAD CELLS 2, tachogenerator 3 are connected with belt conveyer scale main frame 1, frequency converter 4 one ends are connected with belt conveyer scale main frame 1, and the other end is connected with oscillating feeder 5.
A kind of principle of work of multifunction electronic belt conveyer scale is: the belt speed signal that the material gravitational cue that LOAD CELLS 2 collects and tachogenerator 3 collect passes to belt conveyer scale main frame 1 simultaneously, belt conveyer scale main frame 1 obtains material gravity W (t) and belt speed V (t) with the signal that receives through signal condition, calculate then, draw instantaneous mass flow Q (t).Q (t) is compared with set-point, and the process pid control algorithm calculates the controlled quentity controlled variable of frequency converter, and export control signal at last and give frequency converter 4, thus control oscillating feeder 5.
A kind of circuit working principle of multifunction electronic belt conveyer scale is: the AVR one-chip computer with the high speed high reliability is core, gather load cell signal by mould/number conversion chip AD7705 and signal conditioning circuit, gather the pulse signal of belt speed measuring sensor by the photoelectricity coupled circuit, calculate weight of material and belt speed then, calculate mass flow by the mass flow computing formula, and mass flow is calculated.When carrying out mass flow control, the mass flow set-point compares with the streams value that calculates acquisition, its difference is sent into new digital PID controller and is calculated, operation result is by TLV5638 D/A switch chip and XTR115 electric current loop chip circuit, convert 4 ~ 20mA analog control signal to, controlled fixture has the feeding device of regulatory function (as frequency converter etc.), the digital controlled signal of AVR single-chip microcomputer can be exported by the photoelectricity coupled circuit simultaneously, thus the operation of control travelling belt, batcher.This electronic equipment can be stored in each parameter among the inner EEPROM of single-chip microcomputer, the mass flow history data store is externally prevented loss of data after the power down among the EEPROM, can pass through the man-machine interface of keyboard, LCD2004 LCD composition, carry out operations such as parameter setting, real time data inquiry, the inquiry of historical data.Adopt MAX3483 chip and circuit thereof to realize that single-chip microcomputer and computing machine carry out communication by the RS485 agreement, can with PLC, PC or the direct communication of other equipment, adopt the DS1302 real-time timepiece chip to carry out reading of date and time, can be by the correlation function in the keyboard operation menu, the setting on realization time, date, and be furnished with the 3V button cell, still normally operation of clock need not to reset Time of Day after the device looses power after powering on.
The beneficial effect that the utlity model has is: the detection and the totalized function that have both had mass flow, also has pid control function, record and the search function of historical data also are provided, man-machine interface close friend, easy to operate, be applicable to that the feed of industries such as ore dressing, metallurgy, chemical industry, building materials detects and control.
