Description
Technical field
The present invention relates to field of industrial automatic control, relate in particular to a kind of solid material from the method for motion tracking.
Background technology
It is a kind of control technology that combines optical detection, signal processing, data analysis that the material automated location is followed the tracks of, and is widely used at present industrial automation control area.Along with the development of equipment control technology, a lot of equipment can carry out production and processing automatically according to different material parameters, the requirement of ordering goods.Therefore grasp in real time the basis that the position of each material on production line becomes automatic control.Especially in Heavy Plate Production, material is followed the tracks of complicated, and labor workload is large, error rate is high, the steel plate management is very difficult, the difficulty of searching is often arranged, the problem that amount lost is large in the actual production.Although steel plate can not in time be processed according to plan, deliver goods at milling train roll forming, causes larger economic loss.
1. point out in the literary composition at " Computer Control System in Modernized Wide Heavy Plate Mill ": in Wide and Thick Slab factory, rear step operation (being the cold-zone) has large quantities of shearings, finishing equipment, forms some production lines, shears, the operation such as thermal treatment.In addition, also to manage stock bank, middle database, warehouse for finished product.Material processed, cutting in long over thousands of rice, wide by 5,6 workshops that collapse, and shunt in many places, converge, intersect, again processing, technique is moved towards complexity.And in the Wide and Thick Slab production, short run, multi-assortment production account for very large proportion, and material tracking is very important and complicated.
The automatic material that is applied at present metallurgy industry is followed the tracks of the main form of calculating motor speed that adopts.Gather roller-way rotating speed or conveyer chain rotating speed by scrambler, the absolute position of Calculating material is aided with the light sensation detection signal as the check foundation of calculating in real time, and for example CN 101221419A 2..This mode is applicable among a small circle and need to carries out pinpoint occasion to material.Because need the design parameter of related tracing object, such as thing item number, length, speed, weight, volume, position etc., also need in addition the absolute position of defining virtual section, equipment.For different production lines, when adopting the method, need to do a large amount of redesigns, require simultaneously the handover path of tracing object must be according to predefined technique strict implement.The zone is wide, processing is complicated when facing, the various situation in path, and system will be very complicated.
Summary of the invention
For solving the problem and blemish of above-mentioned middle existence, the invention provides a kind of solid material from the method for motion tracking, the method with the material followed the tracks of as the independent logical object, make it in tracing process, not rely on the material self attributes, mean size, outward appearance or other physics when material, do not consist of impact to following the tracks of when chemical parameters changes.Described technical scheme is as follows:
A kind of solid material is from the method for motion tracking, and the method adopts the form of server, client to carry out from motion tracking, it is characterized in that described method comprises:
Key element is followed the tracks of in definition, and described key element is stored as the control parameter;
Read the tracing object record of servers' data memory block, and by graphically showing the user;
Undertaken compoundly by will superpose material throughput direction signal and light sensation detecting element signal of server system, obtain new flip-over type signal, and described flip-over type signal is sent to the data communication units of tracker with the form of electronic message; And
Data communication units is resolved the described text that receives;
From text, follow the tracks of event data and be stored into the data storage area, and process following the tracks of event data.
The beneficial effect of technical scheme provided by the invention is:
The first, adopt the end to end pattern of control, tracing object is divided into two parts of head and tail.It is not the absolute position that any moment all needs material in the Industry Control.In the situation that satisfies the control requirement, adopt and follow the tracks of the calculated load that material method end to end can greatly reduce tracker.
The second, adopt definition tracing object, tracing area, tracking event and between the method for mutual relationship.Material Tracking person only needs to draw zone, the event design drawing in the following range.Require to divide tracing area according to control, then carry out event definition according to the direction of motion of material, can automatically generate the tracking processing logic, do not need to write separately control program.Wide for following range, tracing area is various, the track path complicated situation is very applicable.
The 3rd, not high for the accuracy requirement of detection signal.At the more abominable scene of some environment, the accuracy of detection signal is difficult to guarantee.When the signal abnormal, the wrong treatment mechanism of system will be carried out logic verify based on following the tracks of the three elements rule.
The 4th, carry out the 2 dimensional region definition by matrix pattern.The material that adopts the method can process specific type is followed the tracks of.For example: based on batch tracking, both each tracking event represented one batch integral position and changed.
The 5th, can under any circumstance follow the tracks of correction (online, off-line), adopt the method simple modifications positions of materials of simulating signal, this revises with the method for operation irrelevant, no matter has been to advance, retreat, reach the standard grade, roll off the production line both.
The 6th, when technological requirement and equipment layout change, only need to change the definition of tracing area and the event of tracking, can realize the system reform, do not need reconfiguration code.
The 7th, tracing area and event all are the definition on the logical concept, and they not necessarily will be with in kind corresponding.Therefore the virtual test that can follow the tracks of and control by the mode of simulating signal easily.
