The present invention is simple in structure, it is safe and reliable to realize, and applicability of the present invention is wide, is convenient to standardization and makes, and is conducive to promote the use of.
Below implementation process of the present invention is elaborated:
Obtain the positional information of plasterboard 6, first must know whether that plate enters, on distribution bridge 11, an optoelectronic switch 12 has been installed for this reason, plasterboard 6 enters drying machine 5 when over-allocation bridge 11, and optoelectronic switch 12 can be exported a switching signal to PLC.Because what we paid close attention to is the distribution situation of whole drying machine 5 Nei Ge district plasterboards 6, rather than the particular location of a certain plate, if so a sheet by a sheet plasterboard 6 that enters successively drying machine 5 is regarded as to a queue, we only need to know the position of head of the queue and the tail of the queue of queue so, and this has also just determined the position of this entire team's plasterboard 6.
After having known and whether having plasterboard 6 to enter, also need to know the plasterboard 6 the having entered distance how far of having advanced forward, this has accomplished in many ways.That the most easily expect is s=vt, utilizes the speed of drying machine 5 and time that plasterboard 6 is advanced to calculate distance, and this method seems simply, but implement, to have any problem, can be more loaded down with trivial details.Reason mainly contains 3 points: the one, and the speed of drying machine 5 main transmissions can change along with Main Line Speed, and this makes troubles to calculating; The 2nd, the measurement of speed itself is just not easy to survey accurately; The 3rd, also need Measuring Time, this also has error, with the original speed of larger error and the measured value of time of just existing, calculates distance, and error can be larger.Adopt the method for direct measuring distance herein.A pitch sense switch 21 is installed on drying machine 5 main drive chains, the main drive chain pitch of often advancing, pitch sense switch 21 sends a signal, PLC records the number n of pitch sense switch 21 signals, be multiplied by again pitch c, just obtain apart from s, i.e. s=cn.
PLC processes the signal collecting, and mainly completes following work: the judgement of head of the queue tail of the queue, travel distance calculate, carry out shifting function, abnormal conditions processing etc.
When first group of plasterboard 6 passes through to distribute bridge 11, distribute a pulse signal of bridge 11 optoelectronic switches 12 outputs, activate into plate display routine, system is started working.At this moment system thinks that the head of the queue of plasterboard 6 queues arrives, the pitch n counting that starts main drive chain to pass by, and by result store.Through in-site measurement, the long c=0.288 rice of pitch, so the travel distance s=cn=0.288n of first group of plasterboard 6.In order to facilitate post operation personnel to distinguish fast the position of plasterboard 6, drying machine 5 is divided into 75 junior units, each unit is numbered from front to back, compile as No. 1-75, this is just corresponding one by one with the door of drying machine 5, post personnel know plasterboard 6 is gone to which number door of drying machine more than 5 district at a glance, very convenient.Each width of drying machine 5 is basic identical, be 2 meters, and the local gate-width degree that a few district and district have a common boundary is not 2 meters, and what have surpasses 2 meters, and 2 meters of some less thaies, according to compensation principle, can be approximately 2 meters.Like this, the first group of plasterboard 6 namely position of head of the queue in traveling process is that place door sequence number is m=s/2=0.288n/2, often advances forward 2 meters, and the sequence number of door will add 1.
The judgement of tail of the queue: if distribute bridge 11 to have plate process always, enter plate optoelectronic switch 12 at every turn and all can send a pulse signal, queue constantly lengthens, system can think that tail of the queue does not arrive; If the reason such as useless is put in the disconnected paper of a control or two controls, cause distributing bridge 11 no longer to enter plate, optoelectronic switch 12 do not enter plate during this period of time in can not send signal always, now system can think that tail of the queue arrives, and makes corresponding processing.How long do not enter plate and represent that tail of the queue arrives? drying machine 5 has 8 layers, while entering plate, distribute bridge 11 according to 1,3,5,7,8,6,4,2,1 order-assigned, during normal production, one deck enters plate for twice and is about 110 seconds interval time, if enter so the plate time for twice, be greater than 110 seconds, plasterboard 6 queues of this one deck will be interrupted, i.e. the tail of the queue of queue arrives.In actual production, through debugging, this time be made as 120 seconds proper, plate is not entered at interval for 120 seconds above, system thinks that tail of the queue arrives.
The position that packs data into enters a queue, and data move in whole queue, last position of data in removal queue.When step is by vacation during to true variation, enable bit is set and data block is moved to position of low level.The position of bit address appointment is moved and enters last bit position.First is moved out of queue and is stored in the drawing off in position of control element state byte, and displacement completes.
Can represent with the data queue that 75 binary numbers form in each unit, with " 1 ", to indicate plate by 75 doors of drying machine 5, with " 0 ", indicate without plate.Start after plate, system is by " 1 " shift-in data queue, represent that No. 1 door has plate, according to the actual range measuring, be converted into a sequence number, often the pass by distance of a door of plasterboard 6, system will be in real time by " 1 " or " 0 " shift-in data queue, and legacy data all moves forward one, represents like this plasterboard 6 queues door of having advanced forward.Concrete shifting process is: with pitch number n, be multiplied by the long c of pitch and obtain apart from s, divided by 2, obtain the door sequence number m that head of the queue arrives again, this value and shift count buffer memory are compared, if the former deducts the latter, result is more than or equal to 1, explanation, from the door that advanced again of plasterboard 6 after last time displacement, is carried out one of a shifting function ，Jiang data queue reach, shift count buffer memory adds 1 simultaneously, carries out shifting function next time when plasterboard 6 is passed by a door more by the time.The accumulated value of individual count device is understood zero clearing after reaching preset value, but can not empty data queue, and the preset value of counter is set according to drying machine total length and door number.
With displacement, representing that advancing of plasterboard 6 queues is most suitable, is also the simplest method, and it, is synchronizeed with advancing of plasterboard 6 the past reach of data queue according to the actual travel distance measuring.The more important thing is, it has obvious superiority when processing the discontinuous a plurality of queue plasterboard 6 producing while entering plate.If need not be shifted to represent advancing of plasterboard 6, such as the method for taking to each unit assignment, certain door has plate to this binary digit assignment 1, without plate, gives this assignment 0.Like this can be very loaded down with trivial details, plasterboard 6 door of often passing by, new data more just, whether have plate, also will carry out assign operation 75 times if need to calculate each door, and operand is very large, can take a lot of processor resources, and efficiency is low, programmes also very complicated.
Native system has also designed exception handler, mainly for the processing of the abnormal conditions of drying machine 5 emergent stoppings, closure plate.In 5 li, drying machine, also have plasterboard 6 but main transmission stops Shi， data queue synchronizes with actual conditions, also can suspend and move forward, the main transmission Shi， data queue of recovering to turn round can synchronously move forward along with plasterboard 6 advances.If there is for some reason the situation of drying machine 5 interior closure plates, at this moment the plasterboard in drying machine 56 is improper motion, and cleaning drying machine needs to stop.Native system has designed manual Protection Counter Functions, and when drying machine 5 closure plate, by the clear data data of queue of manual zero clearing, this is corresponding with the bad plate in labor cleaning's drying machine 5, and when after zero clearing, drying machine 5 turns round again, system can be devoted oneself to work again.
The work of display section mainly completes on display module 4 (host computer) picture.Utilize RSview32 configuration software, each schematic diagram of drying machine 5 each districts is drawn on picture, with 75 little rectangles, represent 75 doors of drying machine, with different colours, indicate plate or without plate, the green plate that indicates, redness indicates without plate.Data queue in 75 little rectangles and PLC program is one to one, green red corresponding with " 1 ", " 0 " in program respectively.On picture, also designed the chain rupture warning indication of drying machine; according to the normal speed of drying machine 5 main transmission; main drive chain is walked a pitch approximately 9 seconds; pitch sense switch 21 sends a pulse signal, if exceed during this period of time approach switch no signal always, main drive chain stall is described; if drying machine 5 main transmission run signal also exist; there is transmission fault in explanation, and this may cause due to chain rupture or closure plate, answer hard stop, to scene, checks.On picture, also designed manual reset button, and enclosed operating instruction, while again producing after drying machine 5 closure plate cleanings, used manual zero clearing to empty data, system is reworked.
In sum; these are only better case study on implementation of the present invention, be not intended to limit protection scope of the present invention, therefore; all any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
