Summary
Regard a small-scale sewage disposal project as the opportunity , control the subsystem and procedure design process of controlling the subsystem in the discussion project. First of all, the application of the brief and concise embedded system of introduction in the article, existing working foundation, the customer's demand to project analyses , are designed the process chart to begin by the machinery of the project. Tell ABC designed in systematic programming, the process chart how to analyse machinery to design, explain the functional diagram of the order and important function in the course of programming of UML modeling language, it makes it turn a lot of relatively independent small module detailedly to divide up the complicated large-scale system, and then simplify the programming work. Improve working efficiency. The software and hardware telling the subsystem of controlling and controlling the subsystem is formed basically, every part of package connects the methods, the interface of the communication link is set up . And explain its applied environment.
The workers of Siemens Company have higher occupation rate to accuse of the field to accuse of the series of products while using the market, S7-200 series PLC is one of the members in Siemens SIMATIC PLC family . This project regards S7-200 series products of Siemens as the systematic platform. The introduction focused on is by developing and adopting the course concretly of Siemens' s7-200 series PLC configuration monitoring system. Add and hang EM223/EM222 and expand the module and accuse of some for the on-the-spot worker with miniature PLC of CPU-226 in Siemens S7-200 series in the project one, it is the communication bridge to inject the communication module of CP243-1 , utilize Ethernet to join the highest location machine PC 827B, form the hardware foundation of the monitoring system of configuration. The software respect is with Siemens STEP 7- the Ethernet function in Micro/WIN V4.0 SP6 programming software, join WinCC configuration on 6.26.2 and control the software and form development course with man-machine configuration monitoring system of operating the interface through server software PC Access of OPC. Concrete implementation detail of telling the project from the superficial to the deep; To the characteristic of water treatment trade, the difficult point in the design, describe in detail .

With the developing at a high speed of human civilization, the electron of a large number of automation and mechanical system are developed and popularized . The domestic and international worker accuses of controlling technology increasing rapidly and the computer of modern times , explosion type development of software engineering , promote the innovation of the monitoring system technology of the configuration strongly . Present PLC and configuration control technology not to confine to being can only be used with the heavy-duty equipment together , can all see the figure that PLC and configuration control everywhere in some small-scale equipment and system, using PLC and configuration to control and reduce industry's cost of some large area of small and medium enterprise. No matter in industrial control, or in the commercial field, it is widely used that the configuration controls technology.
The full text is divided into 7 chapters altogether, chapter one Introduction; Chapter two Design overallly; Chapter three Control the subsystem to design; Chapter four The communication link of controlling the subsystem and controlling the subsystem is designed; Chapter five Control the subsystem to design; Chapter six Operate testing and trouble clearing ; Chapter seven The deficiency hit in design and vision of the future.
Mention to
With a small wastewater treatment engineering project, as an opportunity to discuss engineering control subsystem and the supervisory control subsystem of program design process. First of all, this paper brief introduced the application of the embedded system, the existing work foundation, the customer to the project's requirement analysis, the project by the mechanical design of the process flow diagram began. About the design of the system programming basic knowledge, how to analyze the mechanical design of the process flow diagram, this paper expounds the function of order UML modeling language in the diagram and the programming process the vital role, the resolution of the complex large system make divided into multiple relatively independent small module, and simplify programming work. Improve the work efficiency. About control subsystem and the supervisory control subsystem of the software and hardware of the basic composition, each part of the component connection mode method, communication link set of interfaces. And explains its application environment.
Siemens industrial control series products of the company in the field of industrial control application is of high market share and series S7-200 PLC is Siemens SIMATIC PLC in the family member. This engineering to Siemens S7-200 series products for the system platform. Mainly introduced by Siemens series s7-200 PLC configuration monitoring system of the specific application development process. Engineering item with Siemens S7-200 series of CPU-226 miniature PLC EM223 / EM222 use for the expansion module industrial parts, plug-and-socket CP243-1 communication module for communication bridge, using the Ethernet connection first place machine PC 827 B, a configuration monitoring system hardware foundation. Software is Siemens STEP 7-Micro/WIN V4.0 SP6 programming software of Ethernet function, through the OPC server software PC Access connections WinCC 6.26.2 configuration monitoring software constituted with the man-machine operation interface configuration of the monitoring system of the development process. Through the concrete implementation of the telling of the project details; For water treatment industry characteristics, the difficulty in the design, to be presented. Software type selection process, overall system design teams state monitoring system development environment; Hardware industrial control equipment selection techniques, the main function is introduced. PLC programming ideas and several small the techniques; Configuration monitoring system of man-machine interface diagram; A system description of WinCC 6.2 configuration monitoring system and PLC established a connection parameters set example; Configuration C language script specific application example of a few, and the common faults in the operation of the simulation to analyze and solve, explanation debugging process, error analysis of the problem, improve and perfect the process, design the deficiency, the improvement of the late anticipated.
With the high speed development of human civilization, a large number of electronic and mechanical automation system were developed promotion. Rapid growth of industrial control monitoring technology at home and abroad and the modern computer, software technology development of explosive, strongly promote configuration monitoring system of technological innovation. Now the PLC and configuration monitoring technology is not only limited in large equipment and supporting the use of some small equipment and in the system is everywhere see PLC and configuration monitoring of the scene, some small and medium enterprise area of the use of PLC and configuration monitoring to reduce industrial cost. Both in industrial control, or in the business world, configuration monitoring techniques have been widely used.
Full text is divided into seven chapters, the first chapter the introduction; The second chapter overall design; Chapter 3 control subsystem design; The fourth chapter control subsystem and the supervisory control subsystem of communications link design; Chapter 5 monitoring subsystem design; Chapter 6 run the test and troubleshooting; Chapter 7 of the design of the shortages and future prospects.
