Description
Technical field
The present invention relates to a kind of automatic weighing technique of multi-material and device of being used for, belong to computer technology, the detection technique field of controlling automatically, weigh.
Background technology
In iron and steel enterprise's production run, production feeds intake, the continuous data of product rewinding is one of significant data of cost accounting.In (mine, coking, sintering, ironmaking) system, it is various in style to produce the material that feeds intake with the product rewinding before iron, and most belts that adopt transport, and the metering raw data of these materials is mainly derived from field erected belt conveyer scale.
It is more and more higher that present steel enterprise produces the requirement that becomes more meticulous, while is along with the construction of information system, requirement provides by the material continuous data of classifying automatically, and according to hour, order of classes or grades at school, fate add up, instantaneous delivery shows and cumulative amount calculates and existing apparatus (belt conveyer scale etc.) can only carry out the material of transportation, can't meet the demands, can only rely on and artificially collect raw data, carry out statistical summaries again, human factor causes data accuracy not high in the whole link, waste time and energy inefficiency.
Material metering data acquisition at present, read by the operative employee and obtain after calculating behind the weight data of belt conveyer scale instrument, mainly there is following problem: when 1, belt conveyer scale measures multi-material, the weight data that needs manually to read the belt conveyer scale instrument when conversion material kind carries out record, which kind of weight of material otherwise can not distinguish continuous data is, operative employee's labour intensity is big when the multi-material frequent changes.2, when needs according to hour, order of classes or grades at school, when fate is added up the material metering data, need manually to read the weight data of belt conveyer scale instrument according to the time frequency, calculate then and gather because there is deviation in operative employee's timing, cause data error.3, when many belt conveyer scale metering multi-materials, rely on and manually can not finish.
Many material meterings system of the dynamic Machine Vision Recognition control of splendid steel and Shenyang Inst of Automation, Chinese Academy of Sciences's cooperative development, on the band conveyor of carrying multiple iron-smelting raw material between the factory border, this system has been installed all and has put into operation, this system's principal feature is based on dynamic Machine Vision Recognition material, measures then.
The special-purpose measuring instrument NHZK821 of the belt conveyer scale with the sub-material function of measuring type belt conveyer scale integrator that Qinhuangdao electronics corporation of Novartis produces, can be set to various materials is measured by parameter, after being set to the startup of various materials function of measuring, can conveniently realize the classification function of measuring of various materials by the switching of external signal, be applied in power station and some other enterprises and exist the situation that a belt feeder is supplied with the fire coal of a plurality of boilers, accurately measure the coal input quantity of each boiler.
More than these two kinds of systems, all need to adopt specific specialized equipment to differentiate the identification material, only pay close attention to material identification and classification metering, the versatility of equipment, ease for maintenance have restricted the applicability of system, do not relate to problems such as the transmission of material metering data and statistical management simultaneously.
Summary of the invention
