Description
Technical Field
The invention relates to a family returning method, in particular to a family returning method for pickled plate thickness data, and belongs to the field of automatic control of pickling line.
Background
In a plum steel pickling high-strength steel production line, a thickness gauge is positioned at an inlet of a crescent shear and used for measuring the thickness value of a product, the measurement interval is 300mm, the typical sampling time is 10ms, and thickness data are sent to a process control system according to a 1-second sampling average value. As the plum steel pickling high-strength steel production line is a continuous production line, the sampling data of the thickness gauge is correctly classified under the name of a produced roll, which is called thickness data classification, and the data basis for judging the product quality and analyzing and controlling the product thickness by the process is a necessary means for refined production and is one of key data sources of a control system of a steel-making integrated process.
The original thickness data home-setting method comprises the following steps: when the export scissors carry out shearing, the process control system can carry out volume number matching on the newly generated export volume number and the thickness high-frequency data which are not matched with the export volume number. However, from the thickness trend chart of a consistent process control system, part of the head and tail data of the steel coil is not matched with the real object.
Because the thickness gauge is positioned at the inlet of the crescent shear and has certain spatial difference with the outlet transverse shear, when the outlet shear performs shearing, the high-frequency thickness data is divided into two parts, the data going to the coiling machine after the transverse shear is returned to the current produced coil, and the data going to the thickness gauge before the transverse shear is returned to the next produced coil. However, according to the original home-returning method, all thickness data are returned to the current roll, so that the thickness curve data and the thickness of the material roll have deviation, and the thickness judgment accuracy is influenced. When the produced roll is a weld roll, the thickness data is more complicated to home because the process control system cannot identify the identity correspondence between the current roll and the thickness gauge data.
After the research, two invention patents of a thinning compensation method (CN201610991061.8) for improving the control precision of a shearing setting model and a preparation method (CN201310554278.9) of a high-frequency data line for synchronizing a drawing panel and a computer are provided, and a utility model patent of a portable high-frequency data transmission socket connector (CN201520323132.8) based on USB3.0 is provided. One of the thinning amount compensation methods (CN201610991061.8) for improving the control accuracy of the shear setting model is a thinning amount compensation method for improving the control accuracy of the shear setting model; the preparation method (CN201310554278.9) of the high-frequency data line of the drawing panel and the computer is the preparation method of the high-frequency data line of the drawing panel and the computer; however, the specific implementation manner, the problems to be solved and the effects of the related schemes in the prior art are different from those in the present application.
Disclosure of Invention
The invention provides a pickling plate thickness data home-making method aiming at the problems in the prior art, which is characterized in that the fixed physical length between a thickness gauge and a transverse shear is measured and calculated on the production line of the existing pickling unit, the existing basic control system and the existing process control system are utilized to classify output coils into two conditions of finished product coils and welding seam coils, the thickness measuring data of a fixed physical length area are identified and marked under different conditions, and finally the coil number is matched to each thickness high-frequency data record according to the matching principle, so that the coincidence degree of the head and tail data of the steel coil and a real object is effectively improved.
In order to achieve the purpose, the technical scheme of the invention is that the pickled plate thickness data home-making method comprises the following steps:
step 1: accurately measuring the fixed physical length between the thickness gauge and the outlet cross shear;
step 2: identifying an entry number for the thickness data within the fixed physical length;
and step 3: distinguishing whether the head part is brought into the welding line or the tail part is brought into the welding line;
and 4, step 4: and determining a rejection point and matching an exit volume number.
Wherein, the step 1: the fixed physical length between the thickness gauge and the outlet transverse shear is accurately measured, and specifically the fixed physical length is as follows:
DISTINCE＝D1+D2+D3；
d1, thickness gauge to crescent shear;
d2, cutting the crescent moon into a circle shear;
d3, shearing the disc to an outlet cross shear;
the fixed physical length is 1.5+5.1+28 is 34.6 m.
Wherein, the step 2: identifying an entry number for the thickness data within the fixed physical length; the method comprises the following specific steps:
for the current volume, thickness data within a fixed physical length needs to be removed, the fixed physical length is called a removal area, and the part of data in the removal area is a removal point. Classifying the current volume properties:
1) if the current roll is a finished roll: the current volume number is the reject region volume number. Because the strip steel in the fixed physical length and the current coil belong to the same mother coil as the finished coil.
2) If the current coil is a welding seam coil, whether the head part is brought into the welding seam or the tail part is brought into the welding seam needs to be further distinguished;
the head is brought into the welding line, the current coil is a small welding line coil, the head of the current coil and the tail of the previous coil are combined into a small welding line coil, and the PRIMARY coil wound by the current head is used as a PRIMARY coil to generate an outlet coil number. The generated export volume split number is 01 volume, and the current volume number is the number of the rejection area volume;
and the tail part is brought into the welding line, the current coil is a small welding line coil, the tail part of the current coil and the head part of the next coil are combined into a small welding line coil, the parent coil wound by the current tail part is used as a PRIMARY coil to generate an outlet coil number, the generated outlet coil is the last coil, and the next coil number is the rejection area coil number.
Wherein, the step 3: distinguishing whether the head part is brought into the welding line or the tail part is brought into the welding line, specifically:
when the transverse shear shears the steel coil, if the produced coil is a welding seam coil, the basic automation system can give two ID numbers, one is a main ID number, the other is a next coil ID number, and the physical positions of the two ID numbers are explained, but the physical positions of the forward strip steel and the backward strip steel, the main ID number and the next coil ID number do not have a fixed corresponding relation, so that a steel coil process data table is designed in the existing system, and fields are set in the table: the actual number of cutters (actusubid), which corresponds to the entry number. And the inlet coil reaches the transverse shearing position for shearing, and the actual number of the shearing knives is +1 automatically. The actual number of the shearing knives of the forward strip steel and the backward strip steel can be obtained by setting the actual number field of the shearing knives, the current coil is clearly seen to belong to the forward strip steel or the backward strip steel, and then whether the head part of the main ID number is brought into the weld coil or the tail part of the main ID number is brought into the weld coil is judged. Examples are as follows:
for the weld roll, the actual number of shear blades of "main ID number" and "next roll ID number" is obtained, and if actsubid1 is equal to 1, actsubid1 and actsubid2 indicate that the "main ID number" just generates a coil, which is the current weld roll, so the "main ID number" is that the head is brought into the weld roll, and 01 roll is generated, in the rejection area.
If actsubid1>1& & actsubid2 is 0, it is stated that the "primary ID number" has generated multiple wraps, but the "next wrap ID number" has not generated an excess wrap, so the tail of the primary ID number "is brought into the weld wrap and the last wrap is generated, which is followed by the wrap in the culling area.
Wherein, the step 4: determining a rejection point and matching an export volume number;
after the entry number of the reject region is determined, which high-frequency data are the reject points of the reject region should be determined.
Firstly, retrieving the high-frequency thickness data by using the coil numbers of the rejection areas, and performing reverse sorting according to the sequence numbers to obtain the last piece of thickness data, the corresponding sequence number (seqno) of the last piece of thickness data and the speed (V) of the strip steel;
secondly, calculating the running path of the strip steel according to the speed of the strip steel;
Dis1＝V*t；
thirdly, if the running distance of the strip steel is less than 34.6, pointing the pointer to seqno-1, continuously obtaining the next thickness data, and continuously accumulating the running distance of the strip steel to obtain the running distance of the accumulated strip steel; when the accumulated walking distance is larger than 34.6, the thickness data participating in accumulation is the elimination data in the space with the fixed length (34.6 meters)
The method for reversely calculating the traveling distance of the strip steel according to the strip steel speed accords with a high-frequency data collection scene, the parts of the high-frequency data of the thicknesses after inverted sorting, the accumulated travel of which does not exceed 34.6m, are all the elimination points of an elimination area, and the data in a space with a fixed length (34.6 meters) are effectively screened out.
Fourthly, identifying the data one by one without being listed in the range of matching the export volume number; and matching the export coil number to each thickness high-frequency data record according to two types of finished product coils and welding seam coils according to a matching principle, resetting the removed points as normal points, and entering the next round of home-returning processing.
Compared with the prior art, the method has the advantages that the technical scheme improves the original household method through the steps, the fixed physical length between the thickness gauge and the transverse shear is measured and calculated, the output coils are classified into two conditions of finished coils and welding seam coils, and the number of the inlet coil of the thickness data in the fixed physical length is identified. Particularly, for a weld roll, a method for comprehensively judging the actual number of shearing cutters (actual) of the strip steel and the ID number of the strip steel in the front/rear rows is adopted to distinguish whether the head part is brought into the weld or the tail part is brought into the weld, and then the attribution of the thickness data in the fixed physical length is determined. After the coil number of the eliminating area is determined, the traveling path of the strip steel is calculated reversely according to the speed of the strip steel, an eliminating point is determined and set to be in an eliminating state, and finally the outlet coil number is matched with all thickness high-frequency data records in a normal state, so that the aim of improving the coincidence degree of head and tail data and a real object of the steel coil is fulfilled. After the method is applied to production practice, the coincidence degree of the head and tail data of the steel coil and a real object is greatly improved compared with that before the method is applied, and the coincidence degree can reach 97.5%.
