A multi-path transmission mechanism based on topology of dual-band and secondary structure and application on WNCS

For the purpose of improving to redundancy of the transmission path, compensating for poor communication quality of wireless communication in harsh industrial environments and partly improving reliability of industrial wireless networked control system (WNCS), the multi-path transmission mechanism based on topology of dual-band and secondary structure is proposed. The topology of dual-band and secondary structure 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. It partly eased real-time problems on wireless communication technology in industrial environment. At the same time, we introduce to DS-UWB in WNCS firstly. The project of PROFIBUS integrated with UWB are designed on the multipath transmission mechanism based on topology of dual-band and secondary structure. It provides an effective application way of the multi-path transmission mechanism.
