Embodiment Construction

[0031] The work of CEMS on-site control and data acquisition is generally realized by PLC. Generally, PLC manufacturers will configure OPC server for PLC. The present invention realizes communication between hardware through OPC communication technology, including OPC server and OPC client. The OPC server collects the monitoring data information of the field equipment through CEMS, and then transmits it to the OPC client through the standard OPC interface; the OPC client is equipped with a data processing module, a database and a display interface to process, store and display the received data. The database Stores the variable information list and archived data. The content defined by the variable information list of analog and switch variables defined by CEMS monitoring includes CEMS monitoring variables, relevant calculation formulas for flue gas monitoring in CEMS standards, CEMS monitoring status, and data processing and storage rules. and the display interface display fil...

Abstract

The invention provides a CEMS monitoring method based on OPC communication technology. The CEMS is provided with an OPC server and an OPC client, the OPC client is provided with a data processing module, a database and a display interface, the data processing module comprises a set data processing program according to a data processing method required by the CEMS standard, the database is preset with a variable information list of analog quantity and switch quantity defined according to CEMS monitoring. Aiming at data acquisition, storage, control and remote transmission by CEMS in site, the method can be applied to various CEMSs in various fields, such as petrifaction, metallurgy and mining power, has strong adapbility to the demands of users, good stability and is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of industrial automation monitoring, in particular to a CEMS (continuous Emission Monitoring System) monitoring method based on OPC (Object Linking and Embedding for Process Control) communication technology. Realize the collection and processing of monitoring signals in CEMS and send control signals to each switch node in the system, thus providing remote monitoring and monitoring for CEMS, and laying the foundation for equipment pre-diagnosis, maintenance and troubleshooting. Background technique [0002] CEMS (continuous Emission Monitoring System), namely a fixed continuous emission source flue gas monitoring system, consists of a sampling system, a testing system, a data acquisition and processing system, and can collect and process data, generate reports, and control automatic operations. The data acquisition and processing system is mainly composed of PLC, industrial computer and corresponding data pr...
