The present invention is simple in structure, realization is safe and reliable, and applicability of the present invention is wide, is convenient to standardization and makes, and helps promoting the use of.
Elaborate in the face of implementation process of the present invention down:
Obtaining the positional information of plasterboard 6, whether have plate get into, on distribution bridge 11, an optoelectronic switch 12 has been installed for this reason if at first must know, plasterboard 6 gets into drying machines 5 when over-allocation bridge 11, and optoelectronic switch 12 can switching signal of output be given 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 regard the plasterboard 6 of a Zhang Yici entering drying machine 5 as a formation; We only need know the position of the head of the queue and the tail of the queue of formation so, and this has also just confirmed the position of this entire team's plasterboard 6.
Known whether have plasterboard 6 to get into after, also need know the plasterboard 6 that has got into the distance how far of having advanced forward, this has accomplished in many ways.That expect the most easily is s=vt, promptly utilizes the speed of drying machine 5 and the time computed range that plasterboard 6 is advanced, and this method seems simply to have any problem but implement, 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 just is not easy to survey accurately; The 3rd, also need Measuring Time, this also has error, comes computed range with original just existence than the speed of mistake and the measured value of time, and error can be bigger.Adopt the method for direct measuring distance here.A pitch sense switch 21 is installed on drying machine 5 main transmission chains, the main transmission chain pitch of whenever advancing, pitch sense switch 21 sends a signal; PLC notes the number n of pitch sense switch 21 signals; Multiply by pitch c again, just obtain apart from s, i.e. s=cn.
PLC handles the signal that collects, work below main the completion: the head of the queue tail of the queue is judged, travel distance calculates, carry out shifting function, abnormal conditions processing etc.
When first group of plasterboard 6 passes through to distribute bridge 11, distribute pulse signal of bridge 11 optoelectronic switches, 12 outputs, activate the plate display routine, system starts working.At this moment system thinks that the head of the queue of plasterboard 6 formations arrives, and the pitch n that begins the main transmission chain is passed by counts, and the result is stored.Through in-site measurement, the long c=0.288 rice of pitch, the travel distance s=cn=0.288n of first group of plasterboard 6 so.The post operation personnel distinguish the position of plasterboard 6 fast for ease; Drying machine 5 is divided into 75 junior units; Number from front to back each unit, compiles to be 1-75 number, and door with drying machine 5 is corresponding one by one just for this; The post personnel know at a glance plasterboard 6 is gone to which number door of drying machine more than 5 districts, and are very convenient.Each width of drying machine 5 is basic identical, is 2 meters, and the gate-width degree in the place that a few district and district have a common boundary is not 2 meters, and what have surpasses 2 meters, and 2 meters of the less thaies that has according to compensation principle, can be approximately 2 meters.Like this, just promptly to belong to a sequence number be m=s/2=0.288n/2 in the position of head of the queue in traveling process for first group of plasterboard 6, whenever advances 2 meters forward, and the sequence number of door will add 1.
The judgement of tail of the queue: if distribute bridge 11 that the plate process is arranged always, advance plate optoelectronic switch 12 at every turn and all can send a pulse signal, formation constantly extends, and system can think that tail of the queue does not arrive; Cause distributing bridge 11 no longer to advance plate if reason such as useless is put in disconnected paper of a control or two controls, then optoelectronic switch 12 do not advance plate during this period of time in can not send signal always, this moment, system can think that tail of the queue arrives, and made corresponding processing.How long do not advance plate and represent that tail of the queue arrives? Drying machine 5 has 8 layers; Distribute bridge 11 to distribute when advancing plate according to 1,3,5,7,8,6,4,2,1 order; One deck advances plate for twice and is about 110 seconds blanking time during ordinary production; If advance the plate time so for twice greater than 110 seconds, plasterboard 6 formations of this one deck will be interrupted, i.e. the tail of the queue of formation arrives.In actual production, through debugging, this time be made as 120 seconds proper, do not advance at interval plate more than 120 seconds, system thinks that tail of the queue arrives.
The position of the data of packing into gets into the position formation, and data move in whole formation, last position of data in the removal formation.When step by vacation during to true the variation, enable bit is set and data block is moved to position of low level.The position of bit address appointment is moved and gets into last bit position.First is moved out of formation and is stored in the drawing off in the position of control element state byte, and displacement is accomplished.
The data queue that available 75 binary numbers are formed representes 75 doors of drying machine 5, with " 1 " expression plate is arranged in each unit, with the no plate of " 0 " expression.After beginning into plate; System representes that with " 1 " shift-in data queue No. 1 door has plate, is converted into a sequence number according to the actual range that measures; Whenever the pass by distance of a door of plasterboard 6; System will be in real time with " 1 " or " 0 " shift-in data queue, and legacy data all moves forward one, representes the plasterboard 6 formations door of having advanced forward like this.Concrete shifting process is: multiply by the long c of pitch with pitch number n and obtain apart from s, obtain the door sequence number m that head of the queue arrives divided by 2 again, this value and shift count buffer memory are compared; The former deduct the latter if the result more than or equal to 1; Explanation plasterboard 6 after last time displacement door that advanced is again carried out a shifting function, and data queue is moved forward one; The 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.
Representing that with displacement advancing of plasterboard 6 formations is only, also is the simplest method, its according to the actual travel distance that measures with data queue toward reach, with advancing of plasterboard 6 be synchronous.The more important thing is that it has obvious superiority when handling the discontinuous a plurality of formation plasterboard 6 that produces when advancing plate.Represent advancing of plasterboard 6 if need not be shifted, such as the method for taking to each unit assignment, certain door has plate to give this binary digit assignment 1, and no plate is given this assignment 0.Like this can be very loaded down with trivial details, plasterboard 6 door of whenever passing by just must Update Information, and whether have plate, also will carry out assign operation 75 times if needing to calculate each door, and operand is very big, can take a lot of processor resources, and efficient is low, and programming is also very complicated.
Native system has also designed exception handler, is primarily aimed at that drying machine 5 promptly stops, the processing of the abnormal conditions of closure plate.Also have plasterboard 6 but main transmission when stopping in 5 li in drying machine, data queue and actual conditions are synchronous, also can suspend to move forward, and when main transmission recovered to turn round, data queue can move forward along with plasterboard 6 advances synchronously.If the situation of closure plate in the drying machine 5 takes place for some reason, at this moment the plasterboard 6 in the drying machine 5 is improper motion, and the cleaning drying machine needs to stop.Native system has designed manual Protection Counter Functions, and through the clear data data of formation of manual zero clearing, the bad plates in this and the labor cleaning's drying machine 5 are corresponding when drying machine 5 closure plates, and system can devote oneself to work again when drying machine 5 turned round again after the zero clearing.
The work of display part is mainly accomplished on display module 4 (host computer) picture.Utilize the RSview32 configuration software, the sketch map of drying machine 5 respectively being distinguished each is drawn on the picture, represents 75 doors of drying machine with 75 little rectangles, representes to have plate still not have plate with different colours, and green expression has plate, the no plate of red expression.Data queue in 75 little rectangles and the PLC program is one to one, green red respectively with program in " 1 ", " 0 " corresponding.The chain rupture that has also designed drying machine on the picture indication of reporting to the police, according to the normal speed of drying machine 5 main transmissions, the main transmission chain is walked a pitch about 9 seconds; Pitch sense switch 21 sends a pulse signal, if exceed during this period of time near switch no signal always, the stall of main transmission chain is described; If drying machine 5 main transmission run signal also exist; Then the transmission fault has taken place in explanation, this maybe since chain rupture or closure plate cause, answer hard stop, check to the scene.Also designed manual reset button on the picture, and enclosed operating instruction, used manual zero clearing to empty data when after the cleaning of drying machine 5 closure plates, producing again, system is reworked.
In sum; More than being merely preferable case study on implementation of the present invention, is not to be used to limit protection scope of the present invention, therefore; All any modifications of within spirit of the present invention and principle, being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
