Description

Man-machine interface system and design operation method thereof thereof with facilities Control bridge

Technical field

The present invention relates to a kind of man-machine interface system and method for designing, particularly a kind of man-machine interface system and method for designing with facilities Control bridge.

Background technology

Man-machine interface refers generally to realize linking up and interactive hardware and software between user and computing machine, purpose be to make the user of computer system to make things convenient for and efficiently the operational computations machine to reach two-way interaction, finish the desired work of finishing by computing machine, its scope that contains comprises: data input devices such as keyboard, mouse, digiboard, output units such as display screen, audible device.

The system design framework of tradition man-machine interface product is normally integrated various hardware communication interface such as USB, RS-232, RS-422, RS-485, CAN BUS or Ether Net etc. on an Embedded hardware platform.Main CPU (central processing unit) (CPU) in this system has been born the required work of all man-machine interface runnings, comprises work such as picture processing, calculating, input-output device control and Control on Communication.The user the exquisite degree of picture is required to need to take into account simultaneously real-time (Real Time) problem of communication again under the situation of raising day by day, this is the requirement that can't get both for the central processing unit function of a low to medium price level.

The problem of another man-machine interface product design is exactly how to accomplish as far as possible and the communication protocol of each tame equipment manufacturing compatibility that this involves a personal-machine interface product may face the design challenges of change software and hardware architecture at any time under requirement of client.

Under the situation that the wafer production technology is constantly brought forth new ideas, microprocessor is incorporated into the controller interface circuit of various peripheral devices in the framework of microprocessor gradually, its core with a microprocessor is that main body is responsible for numerical value and logical operation, integrate some specific controller unit again, as Memory Controller Hub, get (Cache) controller, timing (Timer) controller, communication controler (as ..SPI, USB, UART etc.) soon ..., Here it is is called the microprocessor architecture design of SOC (System OnChip).

(the Human Machine Interface of Xin Yidai man-machine interface now, hereinafter to be referred as HMI) system design, also therefore by in the past based on simple single-chip or microprocessor design in conjunction with needed peripheral control chip layout, changing into gradually by employing SOC is that the mode of core designs.This will help the elevator system bus speed, the complexity of simplified system design, and also reduced the number of spare parts and the cost of peripheral controller.The appearance of SOC on market is a new revolution for man-machine product.

Yet just the man-machine products-hardware framework of present low price on the market be it seems, all is the control of being responsible for whole man-machine system running by a microprocessor.No matter be under the operating system of multitask or single task, it is awkward that the resources allocation of microprocessor all seems.Especially in industrial control condition, the problem of real-time comes into question for a long time always.Therefore, how to design a low cost and can reach dynamical HMI product, be to be expected by market always.

At present with general HMI product, in order on design cost, to average out a little, usually to sacrifice plotting speed or picture exquisiteness degree for paying the utmost attention to.But in the trend of following HMI product, the high-resolution LCD of high image quality will become main flow.Although the built-in drawing accelerator of follow-on microprocessor possibility will be based on consumer products on using.If on man-machine product, adopt microprocessor platform based on consumer products, application characteristic with man-machine product, microprocessor still do not increase any advantage, because can not be shared the real-time communication protocol computing that enough usefulness is handled more complicated at any time.Therefore, when the man-machine product that this class is general runs into complicated real-time communication protocol, all certainly will have only and adopt plug-in hardware protocol processing module one way.

The viewpoint of another consideration is, when utilizing the built-in communication controler of SOC itself, the software of control and the software of HMI are integrated, and therefore can't independently operate.When HMI has changed the equipment end device that connects, also HMI must be changed simultaneously and supporting communication protocol between it.And, for the software development work of man-machine product, also must constantly increase new communication protocol and upgrade version at different device, this all is puzzlement for man-machine manufacturing plant and client.

Fig. 1 is the hardware structure of traditional basic man-machine interface, it utilizes amicroprocessor 100A to control the work of all man-machine interfaces, comprisesmicroprocessor chip 10A,LCD module 20A,internal memory IC 30A, user's input media (comprisingcontact panel 40A andnumeric keypad 42A) and communication port 50A.Wherein can comprisemicroprocessor 100A,display controller 102A,GPIO controller 104A, UART Universal Asynchronous Receiver Transmitter (UART, Universal Asynchronous Receiver/Transmitter)controller 106A andCAN bus controller 108A in the microprocessor chip 10A.Wherein internal memory IC30A is for storing the memory block (as Flash ROM, SDRAM and SRAM... etc.) of executive routine and data, the circuit control module of communication functions such as thisUART controller 106A has RS-232 in order to extend, RS-422 and RS-485....

Fig. 2 is the software operation pattern of traditional man-machine interface.In general man-machine picture design, the picture deviser need promptly determine destination equipment at the beginning of design, because in the middle of the picture assembly that this parameter adds, all need designated that equipment end points that corresponds to that controller after each.Therefore the deviser will consider picture assembly, destination equipment and communication protocol simultaneously when the enantiomorphic relationship of planning picture assembly and destination equipment.The inconvenience of this practice is, with the method for the direct mapping of destination device description mode, in case need to revise when using different destination equipment, will seem very inconvenient, and will have modification action a large amount of and that repeat and need processed.

And, in the design picture, the user need install different characteristics according to each and plan assembly, so the user possibly can't take into account simultaneously or think deeply when replacing different destination equipment if desired in the future, whether some assembly has special consideration.Therefore, when the design of present man-machine interface product had all faced replacing destination equipment, picture also needed the puzzlement that redesigns.

Fig. 3 is the software operation process flow diagram of general man-machine interface.Man-machine picture deviser is in design during man-machine picture (step S100), at first needs to consider described man-machine label and characteristic with the controller that connects, to determine the communication protocol (step S102) between man-machine and the controller.Remove to select assembly (step S106) according to various controller then, set the attribute (step S108) of each assembly in the picture, and address, the data kenel (step S110) of assembly mapping device are set.If man-machine picture deviser is required to change controller label or model (step S104) in design or after the design, must upgrade the attribute of each picture assembly this moment according to new controller again.Step S112 checks whether finish all component, if picture has 1,000 assemblies, just need correct 1,000 module sets again.And then the compiling of carrying out picture data and communication protocol be connected (step S114) and be downloaded to man-machine interface (step S116) step.This design is the workflow of single-line type, and Renewal Design temporarily in case changed the specification of (purpose) controller, will face the puzzlement that accent comes again midway.

As known from the above, present man-machine product, no matter on the design architecture of hardware and software, all underaction reaches and does not have modular advantage.Therefore, need a hardware platform and can make product again on design of hardware and software cheaply, man-machine operation interface module and communication transfer interface module are designed to separately independently framework, if can use two separate processor to handle separately work respectively, thereby realize designing the purpose of dynamical man-machine interface, make manufacturing plant and client obtain doulbe-sides' victory with low cost.
