Abstract
The paper describes a decentralized data acquisition system installed for a long term on-site test at a French power plant. Two local autonomous stations acquire the information from 24 channels ; the data are continuously transmitted to a concentrator through two 600 m long optical cables at a rate of 0.96 Mbits/sec.. An error ratio lower than 10” on transmission, made possible through the use of optical fiber, allows testing to be performed in an industrial environment using only very simple error detection technique. The optical cables which follow interchangeable paths inside and outside the station, and operate in a temperature range of between -20°C and +60°C, are operational transmission media, which, during testing on large sites, eliminate the constraints related to the location of central computer facilities.
