With the application and development of wireless network in industrial fields, wireless network technology can be applied to control network systems at field control layer, which achieves a hybrid wired/wireless networks with industrial-grade real-time performance. This paper focuses on the integration architecture and performance evaluation of the industrial wired/wireless hybrid networks, and proposes a synchronized optimization method for hybrid integration. A periodic real-time communication model in gateway based on multi-token is established. Especially, a delay model of data synchronization update and data are built in the case of low-speed and high-speed token network. The token cycle synchronization is proposed according to the integration situation, which is significant in reducing network delay and improving delay stability of integration hybrid network. At last performance evaluation on conversion time, control cycle is carried out to study the hybrid integration gateway model and gateway optimization. |
