【導(dǎo)讀】本次所做的設(shè)計課題是基于PLC的自控軋鋼機監(jiān)控系統(tǒng)，系統(tǒng)；也可以是工廠生產(chǎn)過程中的監(jiān)控系統(tǒng)等等。器、傳輸方式或許不同，但它們的工作原理是相似的：一般都是信息采集，信息傳輸，信息處理，信息反饋等幾大功能。

　　

【正文】 ment, when the scene (including the hardware device or system) or user needs change, the need for a lot of modification to facilitate pletion of software updates and upgrades。 (2) packages of (easy to learn easytouse), generalpurpose configuration software functions can be pleted in a userfriendly way to wrap up for the users, do not have too much of the programming language technology (do not even need a programming technique), can be very good to plete a plex project in all the required functions。 (3) general, each user based on the actual situation in the project, the use of generic configuration software provided by the underlying device (PLC, smart instrumentation, smart modules, boards, inverter, etc. ) of I / O Driver, open the database and screen production tools, will be able to plete an animation, realtime data processing, historical data and curves of the coexistence with multimedia functions and work functions of engineering, not sector specific. Developed the first generalpurpose configuration software is DOS configuration software environment, which is characterized with a simple manmachine interface (MMI), library, basic functions such as graphics toolbox. With a wide range of Windows applications, Windows environment into the mainstream of the configuration software. DOS environment and the configuration software into the mainstream. DOS environment and the configuration software, its most prominent feature is the graphics have greatly enhanced functionality. Many excellent 39 generalpurpose configuration software is developed by the English state, it has applied a long time, the user interface is not ideal, does not support or not support the widespread use of free hardware equipment, software configuration costs and training costs configuration software such factors as high, which is the domestic generic configuration software is not widely used in domestic reasons. With the domestic puter industry standards and continuous improvement in the degree of automation, general configuration software growing market demand. In recent years, some technology is strong in hightech panies have been developed for domestic use mon configuration software. System configuration software and its profile In the configuration software, configuration generated through the application of a target item in the puter39。s hard drive holds only the physical space (the logic of space), can be used only to identify a name, it is called an application. In the same puter can store multiple applications, configuration software through the application of the name of the program to access the contents of its configuration, open the contents of its configuration or to modify the application of realtime input into the puter memory to run. Configuration software into a variety of structural standards, here to stage the work of the use of software and software system members to discuss their two standard architecture. The structure of configuration software 1． To use the software division of the work of stage Also can be said to be divided in accordance with the system environment, generally speaking, the configuration software is posed of two major parts: 2． Systems development environment: automated design engineers for the implementation of its control program, in support of configuration software applications under the systemgenerated and must rely on the work of the working environment. Through the establishment of a series of user data files to generate the ultimate goal of graphics applications for the system runtime environment to use. System development environment configuration process from a number of ponents, such as the graphical interface configuration procedures, such as realtime database configuration process. System operating environment: in the system environment, the target applications are loaded into puter memory and runtime. System environment to run programs from a number of ponents, such as the graphical interface to run programs, run programs, such as realtime database. Configuration software to support online configuration technology, which does not withdraw from the system environment can be directly Then enter the configuration environment and modify the configuration, so that the modified direct entry into force of the configuration. Automation Engineering design engineers must first e into contact with the system development environment, through a certain workload and debug the system configuration, the ultimate goal of the application will be running in the system in realtime operating environment, to plete a project. 40 2. In accordance with the membership divided Configuration software because of its powerful, but relatively speaking, each function also has a certain independence, so the form of its ponents is an integrated software platform ponents from a number of procedures. Typical ponents which must include the following: (1) Program Manager (2) interface development process (3) graphical interface to run programs (4) realtime database system configuration process (5) realtime database system operating procedures (6) I / O driver Expansion of optional ponents include: Generic database interface (ODBC interface) configuration procedures Generic database interface software ponent used to plete the configuration of realtime database with generalpurpose database (eg Oracle, Sybase, Foxpro, DB2, Infomix, SQL Server, etc.) of the Inter, the realization of twoway data exchange, mon database can be read by both realtime data historical data can be read。 realtime database is also available from Universal Database in realtime data read. Generic database interface (ODBC interface) environment configuration for the specified database to the exchange of mon database
