Hubei Xingfa Chemical Group Co., Ltd. was established in 1994 and is China's largest manufacturer of fine phosphates and the world's largest sodium hexametaphosphate producer. Xingfa Chemical Group is a company led by the deep processing of yellow phosphorus and its downstream products, while yellow phosphorus is a high energy-consuming product. How to save energy and reduce emissions and reduce production costs is very important for the company's development. The production energy management platform project can effectively link the various production workshops, through the energy management center to unify and rationally allocate energy, significantly improve the company's energy-saving emission reduction and energy management, and maximize the company's production capacity and safety performance. The Production Energy Dispatch Management Platform Construction Project (abbreviated as EMS) is a company-level integrated management-control computer system that integrates process monitoring, energy management, and energy scheduling. It mainly includes integrated management and control of production energy dispatch management platforms and energy management on-site process networks. System, site data collection substation, field control system reconstruction, energy management center construction and other five sub-items. It can realize process optimization and reengineering, improve equipment operation efficiency and reduce energy management costs. At the same time, it can also make timely analysis and take measures according to the system's safety warning to ensure the long-term, continuous and safe operation of the entire production system. Hubei Xingfa Chemical Industry Group, as a pilot company for energy conservation and emission reduction in the petrochemical industry designated by the Ministry of Industry and Information Technology of the State Council, began construction of a production energy dispatch management platform project in 2010. system requirement Moxa solution In the EMS system of Xingfa Chemical, there are two plant areas, namely the Baishahe plant area and Liucaopo plant area. In the selection of factory substation switches, the customer finally adopted the EDS-619 modular compact Gigabit redundant industrial Ethernet switch as the plant house station switch. Since the EDS-619 has 16 Fast ports and 3 Gigabit ports, two Gigabit ports are connected to each other to form a gigabit redundant ring network. Two Gigabit ports of the EDS-619 are respectively connected to the convergence layer switches. The main/standby network connection can effectively guarantee the overall gigabit communication performance and network transmission stability of the system. The EDS-619 is a modular design. The interface is hot-swappable, which greatly facilitates the autonomy of customers in collocation and selection. The EMS system uses the concept of redundancy to improve the stability of data transmission. The two Gigabit ports of the EDS-619 form a Gigabit redundant ring network, support Turbo Ring, and self-healing time <20ms. In addition, two Gigabit ports of the two EDS-619s are respectively connected to different aggregation layer switches, one of which is set as the main connection link, and the other is set as the backup connection link. The data exchange is generally performed from the main connection link. When the main connection link fails or a switching device connected to the main connection link fails, the data exchange automatically switches to the standby link. There are a large number of serial devices and network devices in the factory site. Moxa's outstanding integrated solution can fully meet the needs of customers on site. The Moxa EDS-505, EDS-505A and EDS-508A provide 5/8 ports of 100M. Gather information on various network devices on site. The NPort 6450 and NPort 6650-16 provide 4/16 RS-232/422/485 serial ports to connect multiple serial devices in the field to the Ethernet network. For network communications, Moxa's managed switches all support Turbo Ring's fast redundancy technology and can switch between primary and backup paths within 20 milliseconds. This industry's fastest ring redundancy guarantees the system's line reliability. In addition, field engineers can not only manage and configure the EDS-619/EDS-508A/EDS-505A series of industrial switches through the Web, but also can monitor the status of each port of the network in real time through the network monitoring software integrated with the SNMP OPC Server software. . The Moxa switch has powerful network management capabilities. It can send fault alarm information through E-mail, Relay and OPC data. The SNMP Trap can also effectively capture fault points to ensure that engineers can pay attention to and understand the situation at any time. In Xingfa Chemical Energy Management System, the customer finally selected 12 EDS-619 modular industrial Ethernet switches, 22 EDS-508A/505A/205 industrial Ethernet switches and 27 NPort 6450/6650-16 terminal servers. . In addition, customers also purchase MXview-50 to easily view network topology and device status over the network. The current product is operating reliably and stably, and Moxa's excellent service and responsible work attitude are also impressive. Why Moxa?

- Divided into two factories and one information center
- The interior of the plant is composed of Gigabit fiber respectively, which is connected to the aggregation layer switch. Finally, the information is uploaded to the switch of the core layer switch plant house station switch and convergence layer. The main/standby redundant connection mode is adopted to ensure the data transmission. Stabilized plant house station switch connects up to the nearest tandem center switch, and connects down to the energy collection point access equipment. There is a serial port device and a network device in the field equipment, which needs to be linked to the plant house switch to adapt to the harsh field application environment. , such as wide temperature and anti-electromagnetic interference, etc.
