Summary: The article basically introduced a stage to amount to automation product to control the good and integrated application on the system in plastic mattess forming machine, emphasize reflected a stage to amount to automation product in equipment the tall sex price that electric control system is medium integrated applying is compared, outstanding stage amounts to advantage of plan of conformity of technology of mechanical and electrical products. Key word: RS-485 of PLC HMI communication is introductive: Show plastic nowadays products to apply already generally in production of industry and agriculture and great numerous life inside numerous industry domain, plastic products is opposite cost is inferior, certain respect can replace metal completely to use, function is none inferior also, the article such as the tub that people uses in great quantities in daily life, bucket, bottle all is plastic products, the plastic mattess goods of article introduction also is the requisite in people life, market demand is exuberant, perspective is wide. At present producer goods is raw material of avirulent hurtless chemistry completely, the value is relative more expensive, additionally plastic mattess belongs to new-style mattess product, comfortable and durable, wintry warm summer is cool, won't give birth to bug, service life is very long also, so plastic mattess product belongs to high-grade mattess things, the price fills up tower above than traditional palmy bed a lot of, at present wide application is in southeast Asia country and area, home market just starts, as the progress of social progress and technology, believe before long plastic in the future mattess can replace palmy mattess stage by stage. Control configuration of systematic technology program. Detailed sees next tables: Afore-mentioned form list adduce to control a system only main yuan of parts of an apparatus, in addition still include low-pressure electric equipment (relay of contactor of low-pressure breaker, electromagnetism, electromagnetism, pushbutton, indicator light) , detect sensor (be close to switch, journey switch to wait) , transducer communication cable, all do not grant here give uncecessary details. Block diagram of control system principle is brief introduce: System of control of plastic mattess forming machine uses a stage to amount to man-machine interface to make give priority to a station supervisory equipment, make full use of man-machine interface DOP-A10THTD1 3 communication mouth, join of man-machine COM 1(RS232) issues a news report of PLC controller COM1 mouth, nose of join of COM2(RS485) of man-machine of; of data of parameter of communication trade technology controls a system 12 lukewarm accuse to express, lead plane of man-machine COM3(RS485) join controls a system 11 lukewarm accuse to express, man-machine interface is OK SV of temperature of different control area is worth set, communication of COM2(RS485) of mouth of communication of;PLC of value of indication temperature PV joins 7 transducer, PLC communication writes transducer to give frequency, transducer to start cease an order, read take rotate speed of target of electric machinery of set of interface of man-machine of; of actual output frequency, read take electric machinery actual rotate speed. Control systematic principle block diagram: Craft of plastic mattess forming machine is brief introduce: Plastic mattess shapes cent of equipment machinery share is nose part and leader share, industrial chemicals is added into nose part raw material to fight agitate to add lukewarm, fall through asking in proper technology temperature is controlled, production of nose nozzle treatment gives a diameter very fine cylindrical plastic silk, according to the product different specifications needs, change the diameter that the mould can change columnar and plastic silk, the transportation with constant in a steady stream of many plastic and columnar silk arrives leader share, requirement of different area temperature controls leader share different, plastic silk machines processing through the mould, those who form the sth resembling a net of plastic and columnar silk screen with ply, certain width to interweave is plastic shape goods, again according to set cut out length cut, the product of plastic and webby mattess that can produce a length, ply, width to differ thereby. Program of man-machine interface control is brief introduce: Main component gives priority to machine temperature the picture such as setting of parameter of control of control of speed of electric machinery of control, nose temperature control, frequency conversion, common electric machinery, transducer, different area temperature controls implementation device and plastic shape speed controls a demand, at the same time can parameter of supervisory equipment craft. PLC control program is brief introduce: Main component is PLC control program below a few parts: 1, imitate measures processing: Accept nose to control 2 imitate inside ark to measure signal, after be being changed through maths, 1 comes back as electric machinery of dc timing system rotate speed spends real time numerical value, output 1 imitate quantity to convey to control system of timing of ark ABB dc to nose, give 　 of command; 　 as speed 2, lukewarm accuse a watch to start stop to control; 　 　 3, decide controls a process, differ according to set length, implementation of act of combination of different pneumatic component is plastic and meshy shape fast decide controls product; 　 　 4, transducer communication control: Include transducer to start, cease an order, set linear velocity (M/min) changeover gives numerical value for frequency (Hz) , read take transducer to output frequency actually (Hz) changeover is electric machinery traversal speed (M/min) is numeric. 5, carry control quickly, after the program that cut a knife into parts is carried out movement. Summary: This system of control of plastic mattess forming machine combines a stage to amount to HMI, PLC, transducer, lukewarm accuse implement wait for automation product, developed a stable and reliable product line system for the client, got the client is approbated adequately with use unit, this new product develops a success, the client that the spot sees signed the intent book that buying an equipment at once, for follow-up and congener product the quantity is produced laid solid foundation, report is being amounted to to connect in proving again is the partner that the client is worth to trust.
