Design and implementation of distributed data acquisition system based on fieldbus for large space fire test

It is important to have reliable experimental data for studying compartment fire and developing fire models. A data acquisition system (DAS) based on “fieldbus” technology was developed to capture signals from full-scale burning experiments in the PolyU/USTC Atrium. Such system is demonstrated to have higher flexibility in its network architecture and provide more reliable signals than conventional techniques. In this paper, both the hardware of the instrument and the software for compiling the data will be discussed. This system is demonstrated to be a reliable tool for full-scale burning experiments.
