Research of High-Reliability Transmission Based on Wireless Foundation Fieldbus

For the purpose of improving reliability of wireless Foundation Fieldbus (FF), we increased redundancy of the transmission path and compensated for poor communication quality of wireless communication in harsh industrial environments partly. The multi-path transmission mechanism based on wireless FF is proposed. The topology of dual-band and secondary structure based on FF is designed, and it allows use of independent frequency bands to communication on devices and communication controllers. So as to diminish the chance of conflict and the effective use of space capacity to work in parallel. At the same time, we introduce to DS-UWB in wireless FF. The project of wireless FF integrated with UWB are designed on the multi-path transmission mechanism based on topology of dual-band and secondary structure. It provides an effective application way of high-reliability transmission based on wireless FF.
