Description

Technical Field

[0001] The invention relates to a hot-rolled finished steel plate production technology, and more specifically to a digital tracking method and system for hot-rolled finished steel plate bundling. Background Art

[0002] The existing steel enterprises' 2050 hot-rolled high-strength steel leveling unit's middle plate cross-cutting line shears the steel plates and stacks them into bundles. During the production process, the grating, limit and other signals on the stacking table and the transverse machine equipment are used to determine whether the steel plates have passed the equipment detection method to determine whether there is a steel plate stack, so as to do simple tracking.

[0003] Install gratings, limit switches and other detection equipment in front of the process equipment. After detecting the material, the process equipment sets parameters according to the pre-stored material information. However, the problem with this method is that gratings, limit switches and other detection equipment often generate false signals due to installation, maintenance and other reasons, resulting in errors in the entire tracking process, and often requiring shutdown and manual intervention. Summary of the invention

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0015] Preferably, in step S2, the tracking PLC sends the digital steel plate bundle stacking object at the front of the queue to the stacking PLC.

[0016] Preferably, in step S4, the stacking PLC adds the newly received digital steel plate bundle stacking object to the digital steel plate bundle stacking object set.

[0017] Preferably, in step S6, the periodic processing of the digital steel plate bundle stacking object is specifically as follows:

[0024] Preferably, the method for deleting the data table is specifically as follows:

[0025] When the entire stack of steel plates is judged to be scrapped, the digital steel plate bundle stack object is deleted by the data table deletion method, or is deleted manually by issuing a command through the screen.

[0034] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0035] Combination Figure 1 As shown, the present invention provides a digital tracking method for hot-rolled finished steel plate bundles, comprising the following steps:

[0036] S1. When the stacker starts to stack steel plates, a digital steel plate bundle stacking object is generated, whose data structure is defined in advance, and a unique ID number is generated as a global unique handle to facilitate data association and data indexing and backtracking in any state;

[0037] S2, stacking plate drop signal processing, and stacking plate drop signal is valid, if so, the tracking PLC sends the digital steel plate bundle stacking object to the stacking PLC, if not, return to step S1;

[0038] S3, determine whether the tracking PLC sends / stacking PLC receives successfully, if so, go to step S4, if not, return to step S2;

[0039] S4, the tracking PLC deletes the sent digital steel plate bundle stacking object and refreshes the data column, and the stacking PLC adds the newly received digital steel plate bundle stacking object to the digital steel plate bundle stacking object set;

[0040] S5, judging whether the steel plate stacking is successful, if so, proceeding to step S6, if not, returning to step S4;

[0041] S6, periodically process the digital steel plate bundle stacking object, and event process the digital steel plate bundle stacking object;

[0042] S7. Tracking PLC sends the digital steel plate bundle stacking object to the L2 system for archiving.

[0043] The digital steel plate bundle stacking object includes the following data structures:

[0044]

[0045] In step S6, the periodic processing of the digital steel plate bundle stacking object is specifically as follows:

[0046] According to the running speed of the equipment, the dynamic data (physical position, current speed, etc.) of the digital steel plate bundle stacking object is refreshed by tracking the PLC cycle. When the current steel plate stack enters the process equipment area, the relevant parameters in the digital steel plate bundle stacking object are sent to the current process equipment as process settings.

[0047] In step S6, the event processing digital steel plate bundle stacking object is specifically:

[0048] The gratings and limit switches of the operation line will generate signal events. When the current steel plate stack passes through the grating and limit detection points, the physical positions of these grating and limit signals will be used in the corresponding digital steel plate bundle stacking object to correct the dynamic data in the data table of the digital steel plate bundle stacking object, such as position value and length value, so as to eliminate the cumulative errors that may occur during periodic processing.

[0049] The difference between this correction method and the traditional one is that even if there is a problem with the grating or limit signal of the operating line, simply not correcting the tracking position signal will not cause tracking failure.

[0050] The digital steel plate bundle stacking object itself has a method for creating a data table and a method for deleting a data table.

[0051] The specific method for generating a data table is:

[0052] When a valid shear signal is given or a virtual steel plate stack is manually generated through a screen, a digital steel plate bundle stack object of the current steel plate stack is generated (constructed) by generating a data table, and the digital steel plate bundle stack object follows the current steel plate stack throughout its life.

[0053] The specific method for deleting a data table is:

[0054] When the entire stack of steel plates is judged as scrap, the digital steel plate bundle stack object is deleted by deleting the data table method, or by manually issuing a command to delete it through the screen.

[0055] Combination Figure 2 and Figure 3 As shown, the present invention also provides a digital tracking system for hot-rolled finished steel plate bundles, comprising:

[0056] Stacking PLC1 obtains tracking signals from conveyor roller 2 and transverse machine 3;

[0057] Tracking PLC4 receives the tracking signal of the stacking PLC1 and processes the steel plate stacking data;

[0058] The digital tracking method for hot-rolled finished steel plate bundles of the present invention is realized by the digital tracking system for hot-rolled finished steel plate bundles of the present invention.

[0059] The present invention adopts an object-oriented tracking method. The principle is to use the digital steel plate bundle stack generated by the stacker as a digital steel plate bundle stack object. The object has its own properties and methods, which solves the problem of difficulty in tracking steel plate stacks, greatly improves stability, and has broad prospects for promotion and application.

As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
