Description

The method of seeking starting sequence of sub-control system
Technical field
The present invention relates to the method cutting apart sub-control system in a kind of industrial and mineral control system that is applied to have the sequential control important document and ask for the subsystem boot sequence, relate in particular to the asking for and obtain the method for burden balance discharging order of a kind of many proportioning materials scale systems that are used for indicating the logistics order based on " greatly collecting " with scale material kind.The inventive method also can use with similar sequence control system in, tiered warehouse facility inbound/outbound process system for example, stock yard belt control system etc.
Background technology
Industrial and mining enterprises' feed proportioning system, for example, the auxiliary material and the alloy material input coefficient of steel-making factory often adopt a plurality of burden balance.The corresponding a plurality of upper feed bins of each burden balance are so that prepare various materials in the lump.This type systematic is the scale of proportioning materials more than a many system.
Common industrial and mining enterprises feed proportioning system, technological requirement is simple.Usually feed intake when prescription in setting, only to the requirement of having matched of the kind of required material and weight.To not requiring with the order of the individual species mass transport that is disposed to certain target station.This type systematic digital-to-analogue is set up simple, and the control system program is also simple.Each burden balance only need be by the prescription material in the selected affiliated upper feed bin of prescription, and the weight weighing by prescription is provided with when the material-transporting system conditions being possessed, is discharged into induction system then, carries to the target station.
Gather in burden balance, selected and weighing is intact by prescription, various types of prescription material is overall, is defined as here: " with scale material kind collection ".At every turn before induction system discharging, system allows has " with the scale material kind collection " of material variety to greatest extent, is defined as " greatly collecting with scale material kind " here.For above-mentioned simple feed proportioning system, " greatly collecting with scale material kind " also is that this scale is obtained also weighing by prescription simply from the upper feed bin of attaching troops to a unit, and do not exceed whole materials of burden balance volume and freight weight limit.
Raising along with industrial and mining enterprises' feed proportioning system technological requirement, for example, the raw material input coefficient of AOD of stainless steel steel mill or VOD is in the composition of raw materials, except the setting of material kind and weight, various types of material also will be set to the order of material-transporting system or the discharging of target station.Such system is the scale of proportioning materials more than many system that indicates the logistics order.
Indicate the scale of proportioning materials more than many system of logistics order, it seems has only increased the logistics sequence requirement than conventional system, but the requirement of burden balance system has been increased greatly.The control of each burden balance, not only relevant with this scale in prescription material is provided with related, and the material relevant with other scale in the prescription is provided with related.It is very complicated that system's control becomes.For example, the raw material input coefficient of certain AOD of stainless steel steel mill or VOD, the process desinger illustrates that to auto-control Design teacher the discharging of various requirement sets down in proper order with regard to each " function declaration " that has used ten multipages, and how each burden balance controls weighing and control discharging sequence.Then, the PLC program that auto-control Design teacher is designed arrives the tables of data overload unexpectedly greatly.
Summary of the invention
Technical matters to be solved by this invention provides a kind ofly to be asked for and obtains the method for starting sequence of sub-control system based on " sub-control system unit greatly collection ", and it can optimize sequential control, improves work efficiency and technology controlling and process level.

Embodiment
For method of the present invention is described, uses one below and indicate asking for and the method that obtains burden balance discharging order illustrates in many proportioning materials scale systems of logistics order based on " greatly collecting " with scale material kind.As shown in Figure 1, the present invention includes following steps:
Step 1, real time scan formula table will expects that by the discharging order that formula table is set kind renumbers, by number writing the n formation, from N=N 1To N=N n, element writes down this material kind discharging order N in the formation x, subscript x is from 1 to n corresponding a kind of material, and N is pressed in formation 1＜=N 2... ..N N-1＜=N nRule arrange.N is the maximum species number of this time prescription material, N xThe material discharging order of the i.e. artificial input of value.When artificial formation generation material lower label 1 arrives n, eliminated spacing automatically.
Step 2, definition M yBe the m queue member of " greatly collecting with scale material kind " of being set up by n formation material, on behalf of it, subscript y=1 " greatly collect " position in the m formation with scale material kind to m.Plant from x=n to 1 scanning material, establish y=x, N xBe included into down and be designated as y " with scale material kind collection " and make first member, M y=N x, tentatively obtain original m formation.(if=n) scanning m formation is M to m for y=1 yWith adjacent M Y+1Member N xAnd N X+1Material in the upper feed bin of same burden balance, and N x=N X+1, N X+1Be included into M yThe m formation is with preface carry cancellation " empty set " M successively Y+1, and m=m-1.
Step 3:y=1 is to m scanning m formation, if m queue member My has in the m of same burden balance queue member My+z (z is a positive integer) its value My+z=My value+1, then search for the m formation, if other burden balance not with the equivalent member of My+z, then also all material kind members of My are included into My+z.And then search m formation, and preface carry cancellation " empty set " is former m queue member My successively, and every cancellation one " empty set " is with m=m-1.
Step 4: appropriate repeating step 3, guarantee that at last " with scale material kind collection " queue member of m formation is " greatly collecting with scale material kind ".
Step 5: by following principle is that the subscript 1 to m " greatly collecting with scale material kind " that partition obtains is set discharging serial number: M 1=1, if adjacent subscript only contains the identical material of N value in " greatly collecting with scale material kind ", M then X+1=M x, otherwise M X+1=M x+ 1.
Comprehensive above step, the discharging that just can obtain " greatly collecting with scale material kind " in proper order.
In order to understand this method better, existing is the concrete application of example explanation this method with one AOD of stainless steel steel mill of the factory converter feed proportioning system of steel in the Baoshan Iron and Steel Group.
As shown in Figure 2: there are 20 of upper feed bins (SH1...SH20) in system, six of burden balance (WH1...WH6).Other burden balance are respectively joined four or two upper feed bins with material kind of upper feed bin except burden balance are joined two, and it is corresponding burden balance batching that each upper feed bin can be adorned different material.Burden balance discharge output feeds intake by belt feeder system and three middle hoppers (CH1, CH2, CHL) ladle behind two stations that feed intake (AOD1, AOD2) of AOD converter and stove station that feeds intake.When prescription was discarded, the output of burden balance discharge was discarded to discarded charging basket by belt feeder (BT1, BT2, BT3) system.Feed proportioning system allows to handle in real time the conventional formulation table of AOD.The AOD formula table has eight batches of prescriptions.AOD also has a high preferential batch of prescription and one to handle/blowing batch prescription more again.AOD also has one to use formula table for next heat gives getting the raw materials ready, and three batches of prescriptions are arranged.Each batch prescription can be selected 19 kinds of material at most.19 kinds of material feeding sequences can be specified one by one.Use " greatly collecting " model successfully to handle each batch prescription in this example, solved complicated technological requirement and burden balance furnish component and discharge control problem with scale material kind.
In order to illustrate that " greatly collecting with scale material kind " ask for model and how to solve burden balance furnish component and discharge control problem, following form one: batching batch table, list one group of batch of formula table:
This form is taken from AOD technological design merchant's " function declaration " book.For the purpose of simplifying the description, in " function declaration " book, this batch table is not distinguished main batch still high preferential batch, or handles/blowing batch more again, comprehensively is nine batches.Burden balance also only use WH1, WH3, three of WH5.In order to simplify, upper feed bin numbering is used for substituting the material kind.This type of mass transport that numeral promptly is provided with in the table is to the order of target station.
