Description
Technical field
The utility model is related to weighing system, more particularly to a kind of high precision dynamic weighing system.
Background technology
Before the appearance of continuous weighting device, the weighing or control of product on production line is all manually carried out, i.e.,：Regularly
Take out, weigh respectively.This " sampling check " method, it is clear that be not suitable with the requirement of current high-speed production, but needed one kind
Automatic on-line measurement.Quickly and simply online acquisition and verification statistics are needed in the process of reproduction.If continuously gone out
Existing one group of substandard products, the producer is that should close production line and check reason.Therefore, oneself is impracticable for traditional sample mode, gradually by
On-line checking replaces.Late 1970s microcomputer introduces Weighing instrument, and the development to weighing technology is filled with work
Power.Currently, the automatic title for on-line measurement, is even more to carry out weight not just to underweight product is rejected
Amount control, statistical analysis and processing.
Weighing instrument can work out the reading report of producer's invitation after being connected with computer, for example, real time data
Histogram, the standard deviation of weight, the average value of operation, related parameter report, statistical report, and temporally, quantity
Or the gap report of weight classification etc..Therefore, the producer can be changed in the control room away from measuring station by remote control panel
Variable element, without walking up and down on a production line, the producer even can keep an eye on several production lines simultaneously.For food, change
For the industries such as cosmetic, medicine and chemical industry, the automatic title of this on-line measurement undoubtedly becomes the work for making production manager
Simply, accurately, it is safe and efficient.
Nowadays weighing technology has been indispensable part in human society all trades and professions activity, in ceramic industry
Application it is also more and more extensive.Development in recent years achieves suitable breakthrough, be mainly manifested in weighing measurement technology by
Static measurement develops to dynamic measurement, on-line measurement and modelling direction.Especially in the foundation of dynamic mathematical models, system reason
By, the science and technology such as fuzzy theory, artificial intelligence, neutral net, digital filtering, Theory of Vibration, damping in the field of weighing
Extensive use, the self diagnosis of system, the formation of adaptive and function self-organizing make Weighing at the information of measuring system
Reason is intelligent, modularization and function adaptive direction develop.Because people, which do not require nothing more than, obtains measurement result, also requirement pair
As a result overall merit is carried out, i.e., state estimation, diagnosis or trend analysis are carried out to tested quality.People are actual to be faced, often
It is often dynamic process need to measure in real time, multivariable or system.So, only with traditional measuring method and data processing
It is inadequate, and needs to be set up by means of model and parameter Estimation, realizes intelligent measuring.
Conventional weighing system type mainly has in the market：Static weighing, dynamic weighing, absorption type etc..Various types
The weighing system of formula is adapted to different environment and meets different object demands.Wherein, high precision dynamic weighing system has
The features such as weighing precision is high, adaptability is extensive, man-machine interaction facilitates, applicable and customs, clothes, medicine etc., so more and more wider
It is applied to generally in various products storage circulation systems.
The common method of Dynamic Weighting is concurrently or separately to measure the acceleration of testee, displacement and speed, using number
It is worth the differential equation in integration method solution weighing process, obtains weight.Generally use the Heuristics about weighing system, reasoning
Go out a mathematical modeling containing unknown number, then go fitting to weigh transient signals, in the hope of the ginseng of least squares error
Number estimation.Due to that can be regarded as the final value of weighing process by measured weight, it can be estimated and be measured with model parameter.The system
Theoretical foundation be State-space analysis method in modern control theory, while being also applied to the biography in classical control theory
Delivery function is theoretical.
Two key issues in dynamic quantitative weighing, one is weighing accuracy, and two be speed of weighing, and these two aspects is comprehensive
Close and consider to take into account simultaneously.Dynamic quantitative weighing process contain vibration, time-varying, non-linear, uncertain and random disturbances etc. because
Element, when speed is weighed in quickening, the underdamping concussion of weighing sensor, material impact power change causes vibration and uncertain sky
In fly the disturbing factors such as material and all influence weighing accuracy, reduction is would have to sometimes and is weighed speed.Realize that height is weighed accurately simultaneously
Spend and the dynamic quantitative weighing of higher speed of weighing is one of problem of metering field.
The problem of dynamic quantitative weighing control system is comprising two aspects：One is measurement, and two be control.Quick accurate title
Remeasurement is the quick basis accurately controlled, the accurate measurement of the reasonable selection and weighing measurement link of weighing sensor for
Can the static state and dynamic property of one Quantitative Weighing System be reached for requirement, play vital effect.It is fixed to realize
The fast speed and high accuracy of blanking are measured, what is primarily solved is the dynamic weighing precision problem of system.
Influence the factor of static accuracy weighed：The quantization that the measurement error of weighing sensor, analog-digital converter are brought is missed
Difference, noise jamming error.
Influence the factor of dynamic accuracy weighed：The underdamped oscillation of weighing measurement system, the impulsive force of material blanking, survey
The drop error that delayed (the aerial material) of amount is brought.
Existing dynamic weighing system, weighing precision is relatively low, often can not meet the demand of the system increasingly become more meticulous.
Therefore, those skilled in the art is directed to developing a kind of high precision dynamic weighing system.
