Example Embodiment

[0014] The multi-functional operation monitoring method of the polyethylene production process of the present invention is realized by relying on the three-tier system structure connected by the Internet, such figure 1 Shown. The monitoring system is composed of OPC interface machine, database server, operation station group and monitoring station group. The mutual connection relationship is: OPC interface machine is connected to the DCS system of the production site to provide production process data for the database server. The database server is from the OPC interface machine. To obtain data in the database, the operation station group and the monitoring station group are connected to the database server through industrial Ethernet, and the data in the database server can be read and processed. The OPC interface machine is a data interface device for data interaction with the DCS in the present invention, and it is connected to the DCS system through a DCS data cable. According...

Abstract

The invention discloses a multifunction operation monitoring method for the production process of petrothene, which is realized by replying on three layers of architectures connected by Internet; the method has the advantages of simple network deployment, convenient upgrade, interconnection, update, and maintenance in implementation and application. Plant mode selection is common and standard. The method solves the problem that the current process units of petrothene are short of an omnibearing operation monitoring method and overcomes the defect that a DCS system can not directly realize various advanced monitoring techniques; and the architectures and the plant mode selection can be conveniently popularized and applied to other types of industry devices.

Description

technical field [0001] The invention relates to polyethylene production technology in the field of petrochemical industry, in particular to a multifunctional operation monitoring method for polyethylene production process. Background technique [0002] In the past two decades, China's petrochemical industry has developed by leaps and bounds. Taking synthetic resin at the end of the petrochemical production chain as an example, by the end of 2007, the production scale of synthetic resin ranked second in the world, and the scale of demand ranked first in the world, becoming a veritable world producer, consumer and importer. Vinyl resin accounts for about 50% of the total synthetic resin. Therefore, polyethylene production process and equipment is one of the most common and important equipment in petrochemical enterprises. [0003] There are many production processes of polyethylene resin, but no matter what kind of process, its production operation and equipment operation ar...
