Dispatch of net of machine tool of Chinese numerical control: The article is the introduction of pair of man-machine interface ABC, hope to look right the first time the new reader of the E-Works that contacts man-machine interface is helped somewhat. One, man-machine interface (HMI) product common sense 1, the definition of man-machine interface product joins but program controller (PLC) , the industry such as governor of transducer, dc, appearance controls device, use indication screen to show, take unit through be defeated (if feel screen, clavier, mouse to wait) be written into working parameter or be defeated into operate command, implementation person and machine information are interactive digital facilities, by hardware and software two parts are comprised. 2, man-machine interface (HMI) the composition of the product and product of interface of working principle man-machine by hardware and software two parts are comprised, hardware part includes processor, indication unit, be defeated to wait into memory cell of interface of unit, communication, data, among them the function discretion that the function of processor decided HMI product, the core that is HMI is unit. Differ according to the item category of HMI, processor can choose 8 respectively, 16, 32 processor. HMI software is divided commonly for two parts, the systematic software that runs in HMI hardware namely and the picture configuration software that run at PC Windows control system to fall (be like JB - software of HMI picture configuration) . The picture configuration software that the person that use must use HMI first is made " project file " , the serial communication mouth of repass PC and HMI product, good the work out " project file " download moves in the processor of HMI. Graph 2 man-machine interface 3, the basic function of man-machine interface product and basic skill of type selecting index can: Facility work status shows, if the data such as indicator light, pushbutton, character, graph, curve, character is defeated,enter operate, printout produces recipe memory, the logic with equipment production plain data logging and numeric operation can join a variety of industries dominate index of type selecting of equipment group net: Indication screen dimension reachs colour, the processor speed performance of resolution HMI is defeated into means: Feeling screen or filmy clavier picture keep lay aside size, the unit of capacity that advertent manufacturer tags is byte (Byte) , or (Bit) communication mouth sort and amount, whether to support the function that print 4, man-machine interface product classifies filmy key to be defeated by the HMI that enter, indication dimension is less than 5.

7 ˊ , picture configuration software is free, belong to elementary product. Like POP - screen of feeling of interface of HMI small-sized man-machine is defeated by the HMI that enter, indication screen dimension is 5.

7 ˊ ～ 12.

1 ˊ , picture configuration software is free, belong to intermediate product to be based on flat PC computer, of a variety of communication mouths, high-powered HMI, indication dimension is more than 10.

4 ˊ , picture configuration software collects fees, belong to high-end product 5, the use method of man-machine interface makes clear monitoring job requirement, the HMI product that the choice fits uses picture configuration software to edit on the PC " project file " check and save what already had edited " project file " hardware of PC join HMI, download " project file " to HMI of the join in HMI and industrial controller (wait like PLC, appearance) , is implementation interactive 2, interlocution of man-machine interface product 1, man-machine interface and people often say " feeling screen " what distinction is there? Come from firm sense say, both it is to have substantially of distinction. As a result of " touch screen " it is the hardware part that the likelihood in man-machine interface product uses only, it is one kind replaces mouse and clavier part function, the really before installation is displaying screen is defeated into equipment; And man-machine interface product is a kind of interactive facility that includes hardware and software. In the industry, people constant have feeling to be defeated by the man-machine interface product that takes a function to call " feeling screen " , but this is unscientific. 2, what distinction do man-machine interface and configuration software have? Man-machine interface product, often be called by everybody " feeling screen " , include HMI hardware and software of corresponding special appearance configuration, usually, the HMI hardware of different manufacturer uses different picture configuration software, connective is main equipment sort is PLC. And configuration software is to move at product of software of a below control system of PC hardware platform, Windows general tool, accuse with PC or labour machine also can comprise HMI product together; The equipment sort that current configuration software supports is very much, wait for equipment like card of all sorts of PLC, PC board, appearance, transducer, module, and because the hardware platform function of PC is powerful (main reaction is in go up in speed and memory capacity) , the function of general configuration software is a lot of stronger also, in applying to large supervisory system. 3, whether is there control system in man-machine interface product? Product of anybody machine interface has systematic software share, systematic software moves in the processor of HMI, support much task to handle a function, those who diminutive control system administers systematic software need to move in processor. In the product of high-powered man-machine interface that is based on flat computer, use WinCE commonly, the current telescope mood such as Linux control system. 4, can man-machine interface join only PLC? Either such. Man-machine interface product is to solve the interactive title of PLC and of generation, but the development as computer technology and digital circuit technology, a lot of industries controlled equipment to have capacity of the communication that string together a mouth, the industry that should have capacity of the communication that string together a mouth only so controls device, be like transducer, dc governor, lukewarm it is OK to accuse appearance, number to collect module to wait product of join man-machine interface, will realize interactive function. 5, can man-machine interface pass serial communication mouth of the standard and join of other equipment photograph only? It is below most circumstance such. But the development as the computer and digital circuit technology, the interface capability of man-machine interface product is stronger and stronger. Besides the tradition serial (RS232, RS422/RS485) outside communication interface, product of some man-machine interface already had net opening, and the data interface such as mouth, USB mouth, they but with have net opening, and the industry of the interface such as mouth, USB mouth controls equipment photograph to join, those who will realize the man-machine of equipment is alternant. 6, the facility that whether has communication function can be mixed certainly join of man-machine interface product? Should be such. Because current man-machine interface product was offerred many, the driver of communication of commonly used equipment that can offer an alternative; Usually, the communication driver that answers relatively with join equipment chooses in wanting the picture configuration software in man-machine interface only, with respect to the communication join that can complete HMI and installation. If what choose the configuration of HMI product,the communication driver of join equipment did not want in software, the user is OK the manufacturing dealer that a communication mouth kind that wants join facility and consultative content tell HMI product, ask HMI manufacturer to weave for you the communication driver of this equipment. 7, the PC increases feeling hold, whether direct with PLC communication, the function of the HMI that finish? OK of course. Weave even nevertheless corresponding HMI software, ability makes the PC makes a real HMI product. 8, what is the development trend of prospective man-machine interface? As the development of digital circuit and computer technology, man-machine interface product of future what go up in the function is tall, medium, low differentiate will more and more unidentified show, the function of HMI will be richer and richer; 5.

The HMI product of 7 inches of above will be chromatic indication screen entirely, the life of screen also will longer. As a result of computer hardware capital reduce, HMI product gives priority to the high-end product that is HMI hardware with flat PC computer, because product of this kind of tall really is in,resource of ability of net of sort of interface of processor speed, memory capacity, communication and amount, group, software is shared go up to have bigger windward, it is the development direction of prospective HMI product. Of course, of small size (indication dimension is less than 5.

7 inches) HMI product, what go up in bulk and price as a result of its is windward, increase of the function further as its (if increase IO function) , will get applied extensively in the interactive application of small-sized and mechanical equipment. CNC Milling CNC Machining
