Abstract


The 21st century is the era of the information economy, the Internet became a popular means of information exchange. Industrial Ethernet with its unique advantages of a recognized field of industrial control control network of the 21st century the best solution. Currently, Ethernet-based industrial control systems are gradually replacing the existing fieldbus control system, used in various control areas. This design of the Ethernet control system includes a temperature sampling, testing, control and communications network multifunction control system. In the system design to solve the general Ethernet transmission inherent uncertainty; site equipment supply problems; traditional Ethernet device interoperability is not strong; intrinsically safe and remote transmission and other shortcomings, develop the appropriate technical standards. We use the full-duplex switched Ethernet transmission technology to solve real-time and deterministic communication problems, they use a switching hub to expand network bandwidth, using the UDP protocol to ensure the payload of the packet transmission, to avoid unnecessary padding domain data transmission on the network bandwidth, the network remained at light load operating conditions, to further ensure network traffic in real time. By using a connecting cable idle cable supplies power to field devices, in order to achieve the fieldbus power supply. Ethernet TCP (UDP) / IP protocol, based on the development of harmonized and applied to industrial control application layer specification, also refer to the relevant IEC standards in the application layer to increase user layer, industrial control function block FB standardized by specifying their respective inputs, outputs, algorithms, events, parameters, and put them in a field composed of devices running the application process, easy to implement mix different manufacturers equipment configuration and calls. With low power consumption technology and intrinsically safe field device technology to solve security problems. Adopt appropriate to reduce the signal transmission rate and improved communications interface methods, so that Industrial Ethernet with a more long-distance transmission capability. In the design of application of the PSD module design technology, effectively ensure the system scalability. And, because PSD integrates a variety of programmable logic devices, thus greatly simplifying the hardware circuit, the system design, modifications and extensions become very flexible and convenient. WST used in the design of the company's software tools PSDsoftExpress and FLASHLINK TM JTAG cable to configure the entire chip programming, thereby improving the efficiency of the circuit design and shorten the development cycle, reduce design costs, improve the overall performance, but the system can always updated according to the required conditions implemented on-site. In this module using UMC's UM9008 as an Ethernet controller, making the system not only compatible with Microsoft's Plug and Play function, and is fully compatible with commercial Ethernet; has a wide range of versatility. CPU uses PIJLIPHS company P51XA {3, combined with data acquisition and processing circuit, constitute a field sampling, transmission and control of multi-purpose module, widely adapted to the needs of users, and enhance the vitality of products of great significance.
