Checkout equipment (denotion weight sensor), controller, display screen and the scale pan form a danier scale jointly.This danier scale is placed in operator's console casing.
What this danier scale adopted is the high-precision weighing sensor examining and determine scale divisions value e=10d, and the platform balance precision being used in raw silk size detection than present reeling enterprises improves a lot, and measured value is more accurate.
This danier scale controller principle of work:
Whole system is by forming: 1 power circuit: transfer 220V civil power to DC low voltage power supply needed for circuit system; 2 LOAD CELLS: transfer weight data to voltage signal; 3 filter amplification circuit: filter undesired signal, amplify useful level; 4 D/A converting circuits: the analog voltage collected is converted to digital signal and reads for central processing unit; 5 message circuit: as the exchanges data bridge of central processing unit and host computer; 6 input through keyboard: the instruction of site operation people is inputed to central processing unit; 7 LED display: the weight data that real-time display system collects and certain operations code; 8 temperature protection circuits: prevent system overheat from affecting acquisition precision and damage equipment; 9 vibration protection circuit: vibration equipment can have a strong impact on weighing precision, Real-Time Monitoring environmental vibration data is very important.
Described temperature protection circuit:
According to the practical structures of balance, the thermal source having influence on balance weighing accuracy is divided into internal heat resource and external heat source.Internal heat resource refers to the heating of LOAD CELLS Inside coil originally when energising, and in this case, alleged object is heavier, and the electric current that coil midstream is crossed is larger, and the heating of coil is also larger, thus affects the accuracy of balance weighing.External heat source refers to the thermal source beyond from weighing sensor, mainly refers to the change of ambient temperature, as the heating, the heating of electronic devices and components, the change of room temperature etc. of power transformer.
In order to more effectively compensate, two kinds of thermals source separate and process by system.
(1) compensation of internal heat resource
The heating of coil is that the electric current himself flow through produced, and with alleged object light, heavily change and change.
Solution is:
In coil, add the exchange current that a positive and negative amplitude is equal, make the effective value of the total current flow through in coil constant, thus eliminate the change of coil heating, also just eliminate due to weigh change and cause change.
(2) compensation of external heat source
From electromagnetic theory, the size of the Lorentz force F produced in the magnetic field of magnetic flux for B for I, the length wire that is L that alives is:
F= B L I
Another according to force balance principle, can obtain
F= m g
Therefore B L I=m g namely: I=g m/ B L
According to Ohm law, have:
V = I R
I can be influenced by ambient temperature and change, and in order to make the V value of the object of same weight consistent, needs R also variation with temperature and changing.
Solution: as shown in Figure 6.
Circuit is given a sample resistance R1 thermistor R2 in parallel, like this
V1 = I1[R1R2/(R1+R2)]
Wherein V1 is voltage signal; I1 is current signal; R1 is sample resistance; R2 is thermistor.
According to the situation of change of actual temp value, a selected suitable R2 value, when making temperature variation, the value of R1R2/ (R1+R2) is constant, just achieve the constant of same object voltage signal V1 value at different temperatures, thus the error that elimination external heat source causes temperature variation to produce balance measurement result.
Described vibration protection circuit:
Below LOAD CELLS, installed shock sensor, arrange the maximum detected value of vibration, when the vibration signal of LOAD CELLS is less than maximum detected value, data are read in CPU protection; When the vibration signal of LOAD CELLS is more than or equal to maximum detected value, export a signal to CPU, control CPU abandons the data of this time, again again detects raw silk weight, and gets the data that again detect as valid data.Thus the accuracy that guarantee is weighed.
Cpu command LOAD CELLS works, weight data is transferred to faint voltage signal with certain algorithm, faint voltage signal filters interference level after amplifying circuit after filtering, useful level is amplified to the voltage range of applicable digital to analog converter conversion, convert digital signal to finally by A/D change-over circuit to read for central processing unit, so just complete the collection of a weighing data, central processing unit draws the weight of this time weighing through data acquisition and computing, judge that whether data are effective by vibration and temperature monitoring, then be supplied to LED display show in real time or gone out to host computer by communicating circuit.
