Additional, labour of Ⅲ of 4 high-powered P accuses machine serve as a system go up a machine, undertake through aether net and PLC data conveys, the monitoring that machine of the casting that finish produces, among them 3 stand for operator, each other is reserve, use at real time monitoring of production; 1 stands for the engineer, can complete pair of software systems consult, revise wait for the job (if the graph is shown 1 times,the system configures a graph) . 4, function of control of software design, system and implementation 　 4. The design of 1PLC program: Control program uses Rslogix5 of software of special process designing of company of automation of Luoke Wei Er, use the echelon that understands easily simply to scheme pattern weaves and be become entirely, cent sheds control program for public control program and casting in all 4. What every control program all used popularity is modular / method of structured process designing: What the basis dominates end of object, control is different it is control program cent a certain number of control parts, scanning every time by the main program in cycle ordinal call will realize respective control function; In file of each echelon graph, put the program with control same function in same control paragraph in, try annotate. Method of process designing of this kind of structuralization makes of the program consult, it is more easy that functional augment reachs long change to get, the flexibility that enhanced a process greatly, readability, practical and safeguard a gender. 4. The design of 2 supervisory system: On supervisory system uses Rsview32 to make, rslinx is in charge of completing the data news report with PLC. The basis produces the craft, demand that controls a function, made 9 much in all, add up to picture of more than 40 monitoring. 4. 3 main control functions reach the implementation of crucial technology: Basically control a function: The fundamental class automation that this automation system basically produces with Yu Lianzhu machine is controlled, what through using A-B automation to control a technology achievable foundation produces process is full automatic turn control, those who realize equipment of site of the production that connect casting is automatic and interlocking, of medium temperature, pressure, discharge detect adjust, the communication processing of data, breakdown calls the police and the function such as the online monitoring that produces a condition. Main control function has: Intermediate tank car walks, litre fall function; The discharge of crystallizer cooling water, 2 cold water, public medium and pressure detect adjust function; The machine that choose steel controls a function: Sideslip machine controls a function; The molten steel of big package, intermediate bag is measured lukewarm reach say to weigh a function; Big Bao Xuan turns reach litre fall control; Hydraulic pressure station is controlled; Crystallizer vibration is controlled; The machine that pull correct / pull Jiao Gun to control; Export roller path control; Crystallizer cooling water is controlled; 2 cold water are controlled; Dog automatically control; The online monitoring of blaze cut control and production. The implementation of crucial technology: Technology of ① frequency control control: The equipment such as machine of the intermediate tank car, machine that pull correct, path of roller of crystallizer, output, sideslip all used frequency control to control a technology. PLC passes means of communication of Scanner of RemoteI/O 　 　 to will control a command to communicate transducer, the status that receives transducer at the same time feedbacks in real time information; Control program criterion to will be opened through using MOV to dictate / stop, / invert, the order information such as speed set-point conveys with outputting the data format of the word transducer, implement the automation of frequency control thereby. ② of 2 cold regions full automatic control matching water is algorithmic: The curve of 2 cold control matching water of theoretic ideal is a 2 second curves: F=aV2+bV+c, but it is very difficult that implementation rises. For this, we use technology of linear emulation curve: Those who use 3 slope to differ is linear come imitate 2 curves, the basis is pulled currently fast value of the A that reachs correspondence of 3 linear place, B is calculated respectively a F1 of 3 quantities matching water, F2, F3, take its maximum to serve as current actual set-point next: F1 of ｛ of =Max of Fsp 　 　 , f2, f3 ｝ (if pursue,show 2 times) . In addition, through PID the instruction achieves 7 paragraphs of return on software appearance adjustment is controlled (control block diagram sees a picture 3) . Graph 2 graphs casting of ③ of 3 　 　 flows to dog automatically technology: PLC basis A-B increment coder (installation helps correct aircraft at 3# , 1024 pulse / circle) send the pulse to pattern plate of high speed computation to count, be calculated automatically and finish send the mode that bring ingot, pouring the machine pulling correct below mode / the roller that pull correct, 2 cold regions match water, electric machinery to measure fast and casting base is measured long etc full automatic control. ④ blaze cut controls a system oneself: This system uses PLC of 　 of 3 SLC500 　 alone, built DH+ communication method and PLC5 to have data news report. Send the casting base that come over to measure data of long real time according to PLC5, implementation is controlled to the automation of billet cut, have 2 kinds of scale (this machine, on) , 3 kinds of mode of operation (the hand is moved, semi-automatic, full automatic) control function. The casting base use that at the same time PLC5 controls the movement that exports roller way to end cut according to the feedback information of SLC500 goes out. Those who control a program to use MSG instruction to realize communication data information is mutual deliver. The technology of automatic and online monitoring that ⑤ casting machine manufactures: Used Rsview32 monitoring technology, Rslinx communication technology to develop the online supervisory system that casting machine produces. Cent of this supervisory system is hydraulic pressure of total appearance, fan station, condition and condition, public detect, control of face of cooling water of one cold, 2 cold, equipment, fluid and other 9 much, have following main functions: Produce the online indication monitoring of status of data, facility; Produce data go up a set and the control alternative that produce pattern; The teleregulation of the long-range control of the choice of means of device control character and equipment, medium; Trend record, breakdown calls the police, forms for reporting statistics is printed and systematic breakdown is diagnosed oneself. 5, the last word should control a system oneself integrated and compositive technology of the PLC control technology of company of automation of American Luo Kewei Er, picture monitoring technology, network news report and frequency control technology, came true to produce even casting machine base the automation control of process, achievable Lian Zhusheng produces the automatic and interlocking control of spot equipment, of medium parameter detect adjust, the communication processing of data, breakdown calls the police diagnose and the function such as the online monitoring that produces a condition. Through 3 years of much moving test and verify, function of this system control is safe and advanced, stable reliable, improved labor productivity effectively, improved working environment of the staff member, reduced labor intensity of the staff member, the direct motion that is production provided reliable safeguard, obtained very remarkable economic benefits.
