Abstract:

A new method used in power plantside real data acquisition was introduced. The field data acquisition module is made up of the data transmitter

and the COM component, which is installed in the industrial control computer of the continuous emission monitoring system (CEMS). The field data

acquisition module had been developed and used in Jiangsu coalfired unit FGD realtime monitoring and information management system; and the result shows

that using the field data acquisition module, the development and debug cost was reduced, the system stability was enhanced, and the data privacy was

realized.

Key words: monitoring of desulphurization system, field data acquisition, COM component, data transmitter
