Interface of article introduction man-machine disinfects the applied circumstance of product line in bottle of water needlework glass. Develop as industrial automation pilot, a kind of new class accuses product man-machine interface (abbreviation touchs screen) appear, give industrial equipment spot to control a kind of brand-new graph to operate interfacial ─ (GOT) . It is used can the 32 RISC chip that high speed corresponds, it is good to have alternant sex, process designing is handy, agile, and as handy as the join between PLC, simplify control ark design, the actual input of economic PLC outputs a dot, begin to receive promotion application in industrial device control character. It is with product line of disinfection of bottle of water needlework glass now exemple, introduce systematic configuration and application. One, if sketch map of technological process and equipment of product line of disinfection of bottle of glass of requirement water alignment pursues 1 is shown. Vitreous bottle is entered from entry point, come up against sensor 1, start take away machine belt, drive bottle to move toward exit from the entrance, contaminated area of area of warm-up of by way of, disappear, cooling zone. Import fan, hot fan, exit fan, platoon fan to run only, ability goes belt. If the entrance is in,pass into bottle fast, extruding sensor gives out signal 2 times to stop ahead equipment to stop to take bottle. If export not free, sensor 3 issue signal, stop to take mechanic to make. There should be to stop only in 5 fan machine, stop heater to move, call the police show. Detect fan does not move have pass feeling switch to hold the exit in fan, the breakdown of fan transducer outputs a dot to enter PLC, walk along the contact of air switch tripping operation that takes machine and each electric machinery to also enter PLC, heater installs the central coping in furnace, diffuse equably downward by sirocco machine add lukewarm. The requirement has the setting of different temperature to the Bo bottle of different type size. Can show the temperature of each area is worth, and of respond temperature walk along situation graph. Should have to entering fan, hot fan, exit fan can detect the numerical value of its leeway shows, in order to decide whether screen pack jams. Graph when sketch map of equipment of 1 product line is working normally, after the job comes off work, drop when temperature 100 ℃ are the following, equipment can close automatically machine. If there still is bottle to was not handled inside furnace, start nightwork. Stop machine hind below in 100 ℃ so, still entrance fan, exit fan works, in order to assure external dirt cannot enter furnace inside. To disinfecting time, collect the data of exit sensor by PLC, pass time of speed translate into, will show Bo bottle to disinfect time in what disinfect an area, the dependability that disinfects in order to ensure. Equipment falls in safeguard, ask can accurate indication breakdown produces a dot to reach solve problem countermeasure picture, animation reflects condition of manufacturing site job. 2, systematic configuration asks to above, we are chosen in amount to - composition of the man-machine interface of Si Mike company, PLC controls a system. Specific as follows: 1. Man-machine interface model is PWS-3760-TFT, this screen is true color 10.

4 inches of screen, use 232 to undertake download and process designing, use RS422 mouth and PLC news report. Choose true colour to be able to reflect spot view better, animation is distinct, beautiful. 2. PLC chooses SC, 500 series, this machines and tools has function of 1024 bits of inputs, output, mouth of communication of a RS232 and mouth of communication of a RS422, be a kind modular type, can configure dot of functional module and input, output neatly. 3. Input choosing matchs XDC10 DC inputted module at 16 o'clock 2, output matchs a YRY10 relay outputted module at 16 o'clock. 4. Emulation input unit uses AD020 4 inputs module, input value of a quantity of 3 leeway imitate (4mA ～ 20mA) . 5. Temperature input unit uses THM10 5 belts output of PID adjustment PWM is lukewarm accuse module 1, collect enter 3: The temperature of contaminated area of thermal treatment zone, disappear, cooling zone. If the graph is shown 2 times,its system is formed. Graph 2 systems configure a graph 3, debug moving circumstance this system is the most important is pilot of precision of temperature of offset contaminated area debug, of disappear contaminated area heat the system uses unit of silk of 5 groups of electric heat to heat, among them one group is heat basically unit, other quadruplet heats for PID thermoregulation unit. This product line uses OMRON PLC previously, the circumstance at that time is: Product line tries when moving, range of wave motion of occurrence temperature curve is too big (± 8 ℃ ) . The index of alexipharmic temperature wave motion that exceeds manufacturer requirement (2 ℃ of ± ) . Two measure were adopted to undertake controlling to extent of temperature wave motion when be being debugged actually. (1) use two-step PID temperature to control a system to stem temperature downtrend. Detect when platinum thermistor temperature of disappear contaminated area under set temperature when 1 ℃ . Through two-step PID temperature control system makes PLC heats 7 groups unit and total investment runs 30 seconds, detect through platinum thermistor next temperature of disappear contaminated area, by lukewarm charge unit PID control, achieve set till temperature till the value. (2) the control that temperature moves an amount too. Undertake detecting to disinfecting area temperature above all, if temperature is more than set value, PLC heats 7 groups unit is excised forcibly entirely, detect ceaselessly temperature of disappear contaminated area, make real time control according to actual condition, certain to controlling the certain parameter of the program to make modification is passed in the spot. Debug through relapsing, final temperature controls precision to accord with manufacturer requirement completely. In the in debugging discovery to the system, this control system can pass pair of programs completely to make farther modification, debug. Achieve higher temperature to control precision. Using SC, 500 hind, PID of because our THM10 is OK separate set is worth, because this is very convenient stabilize temperature in losing 1 degree inside, exceeded craft requirement. 4, this system uses the last word on equipment of product line of Bo bottle disinfection, good to disinfecting degree of control, can undertake indication to each area temperature, undertake installing to the alexipharmic temperature of different Bo bottle. Once spot breakdown happens can shoot a picture of countermeasure of one detailed breakdown immediately. Via the spot working circumstance looks, satisfy design requirement. This system is the expert countermeasure system that a kind of intelligence changes, enhanced interactive sex, improve the control performance of equipment, simplified to operate ark design, raised content of equipment science and technology, in the market very competitive, have space of very great progress.
