I. Overview
Sichuan Pharmaceutical Co., Ltd. uses the fiber-optic deep power workshop to control the operation of two Jonathan 550 air compressors in the whole plant LAN design, and joins the dispatch management system to infiltrate the Ethernet into the industrial site to realize seamless office automation and industrial automation. Combine and provide assistance to the dispatching room and the chief engineer of the plant at any time. Fully use the AI ​​series of intelligent instruments to build a fieldbus computer monitoring system to connect to the shared information resources on the LAN. Make the workshop, dispatching room, and factory office computer form a peer-to-peer Ethernet, and realize the integration of resource sharing management and control.
Second, the system architecture We put the traditional server to the site to act as a server, the computer installed WWW network version of the industrial control software, the field instrument data is collected by the server in the form of digital signals and stored in the server.
Regulator AI-808AXL2L2S4 inspection instrument AI-706MAJ0J0J0L2L2S AI table collection of pressure, flow, temperature, displacement, liquid level, flow and other data stored in the customer server WWW network version of the industrial control software database, installed on the computer 100M network card, connected The optical transceiver is a four-core optical cable that is sent to a 16-port 100-megabit adaptive hub (HUB) at 500 meters (up to several kilometers) to form a corporate LAN, so that the computers in the entire LAN become peer-to-peer Ethernet. By assigning an IP address to each computer, the parameters of the industrial site quickly transmit images and data through the optical fiber, which satisfies the actual needs and reduces the cost.
Any management machine in the enterprise network can exchange real-time flowchart data with the on-site server. All computers become peer-to-peer Ethernet (see figure). Users can query field data and process parameters through the standard IE browser of their respective computers. Really share resources to simplify complex network configuration and save hardware investment.
Third, the network hardware executive layer
The network backbone uses optical fiber to directly penetrate the optical fiber cable and Ethernet technology into the workshop. The industrial site adopts AIFCS fieldbus computer monitoring system, and the smart instruments on the site are connected by super five shielded twisted pair cables. Each station is connected with 101 instruments (101 address codes) and passed through the optical converter (RS232/). RS485) plugged into the serial port of the computer,
The link system of the entire network determines that the main line of the factory area adopts the optical cable structure. Since the optical cable can eliminate the surface potential difference and other electromagnetic interference sources, the transmission frequency bandwidth, the information volume is large, the transmission loss is low, the relay distance is long, the security is reliable, and the optical cable is light in weight. Easy to construct. Multi-mode fiber should be used for computer local area network. When using optical fiber as data backbone, it is generally used with 4 cores, 6 cores and 8 cores. It can be laid in overhead and trough trenches. For every 50CM bracket, the ends of the cable must be welded to the pigtails. Fixed to the fiber terminal box, to the wall mount, pigtail and fiber transceiver connector to ensure clean, so as not to affect the transmission, the hub should be installed in the center of the LAN, the subsystem uses Category 5 standard unshielded twisted pair wiring. With 100% compatibility with mature Ethernet technology products, the Ethernet application industry site is by far the most ideal choice. It can fully consider the future development needs, with high transmission rate, and now to 100Mbits/s, high transmission security and reliability. Sex, collector technology determinism almost does not need to consider the network topology, transmission of physical media, twisted pair, fiber, coaxial cable, hub applications can be considered without the expansion of the network, using Windows98, NT, TCP / IP protocol Peer-to-peer Ethernet for easy integration with public data networks for global networking across the entire plant.

Fourth, system functions,
Features: (1) WWW network version configuration software, introduced advanced thin client mechanism, that is, only need to have Microsoft Imternet Explore5.0 or above web browser on the client, you can carry out various tasks on the spot. Browse, even control, without having to install any software on the user's computer. That is to reduce the software purchase cost, user training and maintenance costs of the client software. At the same time, the production site control system can be fully explored, enabling the entire enterprise manager to view the production status of the entire plant on his own desktop.
(2) Ability to perform on-line detection and diagnosis of operating field devices. Through simple configuration, the engineering curve, report, data browsing and analysis, and WWW release of animation display can be realized, and the scene can be known anytime and anywhere.
(3) Intranet integration that facilitates device management and enterprise management.
(4) Adopting a layered authentication method and having a complete security mechanism can fully guarantee the security of the enterprise running equipment and information system.
(5) Powerful data reporting function, through the seamless connection of Microsott EXCEL, the report mode can be compared with the provided report.
(6) The extended curve function can display 100 curves simultaneously on the same page, corresponding to the curve, providing an intuitive and accurate digital display. The peak value of each curve can be obtained through a special button.
(7) Provide support for various heterogeneous networks, connect media support as you like: twisted pair, fiber network domain support: local and wide area Internet connection support: dedicated line and Modem dialing (8) to provide personalized users Customized functions, users can choose the appropriate WWW template to achieve different browsing styles according to their needs.
V. Conclusion
In the current situation of the field bus field, the field bus is close to the Ethernet, which is a trend in a certain period of time. It is reflected in the efficiency and benefits obtained by the enterprise. It is the key to grasp the industrial site and enterprise operation status anytime and anywhere. It is the key to accurately and timely understand the required information, greatly improve work efficiency and achieve successful decision-making.
With the rapid development of computer and network technology, most domestic manufacturers have established their own computer local area networks. You work in a highly office automation environment, your PC can access the Internet at any time, inquiring and exchanging information with others, on the other hand, you need to know anytime, anywhere, in a factory workshop, there is a very advanced Monitoring system, such as AIFCS fieldbus computer monitoring system built by Yuguang AI instrument. How to help you understand the production status of the workshop, such as the operation of the machine and the chemical reaction of the product, including the monitoring system can collect a large amount of data and information you need. If your on-site monitoring system is not connected to the network, it can only be used as an island of information and cannot be sent out smoothly.
Ethernet is currently the most widely used LAN technology in the world. With the rapid development of the Internet, Ethernet has become the de facto industry standard, and the simple and practical TCP/IP protocol is accepted by users. With the development of communication, network technology and smart meters, Ethernet technology has the ability to extend to the industrial site, that is, Ethernet can be built into the industrial field I / O level, thus achieving a seamless integration of office automation and industrial automation To form a truly open, interoperable monitoring system in the true sense. Since the LAN layout is generally twisted pair, the distance is controlled within 99 meters, and your workshop is a few hundred meters to several kilometers away from the management. Ethernet products must be introduced, fiber optic cables and fiber optic transceivers should be configured, and the machine should be directly penetrated into the workshop. The management is connected, so that the Yuguang AI instrument becomes a reality through the field bus to the Ethernet, and it becomes the enterprise information of the true meaning.
