Description
Technical field
The present invention relates to field of industrial automatic control, relate in particular to the method for a kind of solid material from motion tracking.
Background technology
It is a kind of control technology that combines optical detection, signal processing, data analysis that 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 position of each material on production line and become the basis of automatic control.Especially in Heavy Plate Production, material is followed the tracks of complicated, and labor workload is large, error rate is high, steel plate management is very difficult, often has the difficulty of searching, the problem that amount lost is large in actual production.Although steel plate, at roll forming of milling train, can not be processed according to plan in time, deliver goods, and causes larger economic loss.
1. one the article pointed out at " Computer Control System in Modernized Wide Heavy Plate Mill ": in Wide and Thick Slab factory, rear step operation (being cold-zone) has large quantities of shearings, finishing equipment, forms some production lines, shear, 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, processing again, technique is moved towards complexity.And in Wide and Thick Slab production, short run, multi-assortment production account for very large proportion, material tracking is very important and more 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 in real time, is aided with light sensation detection signal as the check foundation of calculating, and for example CN 101221419A 2..Which is applicable among a small circle and need to carries out pinpoint occasion to material.Because need the design parameter of associated tracing object, 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, need to do a large amount of redesigns adopting when the method, require the handover path of tracing object must be according to predefined technique strict implement simultaneously.When facing, region is wide, processing is complicated, 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 the method for a kind of solid material from motion tracking, the method is using the material of following the tracks of as independent logical object, make it in tracing process, not rely on material self attributes, mean in the time that size, outward appearance or other physics, the chemical parameters of material change and do not form impact to following the tracks of.Described technical scheme is as follows:
Solid material is from a 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 controlling parameter;
Read the tracing object record of servers' data memory block, and by graphically showing user;
By server system, stack material throughput direction signal and light sensation detecting element signal are carried out compoundly, 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
The text receiving described in data communication units parsing;
From text, follow the tracks of event data and be stored into 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 pattern of controlling end to end, tracing object is divided into two parts of head and tail.It in Industry Control, is not the absolute position that any moment all needs material.In the situation that meeting control requirement, adopt tracking material method end to end can greatly reduce the calculated load of 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 region, the event design drawing in following range.Require to divide tracing area according to controlling, then carry out event definition according to the direction of motion of material, can automatically generate tracking processing logic, do not need to write separately control program.Wide for following range, tracing area is various, track path complicated situation is very applicable.
The 3rd, not high for the accuracy requirement of detection signal.At the more severe scene of some environment, the accuracy of detection signal is difficult to ensure.When signal occurs when abnormal, the wrong treatment mechanism of system will be carried out logic verify based on following the tracks of three elements rule.
The 4th, carry out 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 change.
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 correction and the method for operation are irrelevant, no matter have been both to advance, retreat, reach the standard grade, roll off the production line.
The 6th, in the time that 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 are all the definition in 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.
