Analysis of time structure in the industrial hybrid network

A hybrid network topology that is composed of the traditional industrial bus and wireless sensor network, it is suitable for industrial scenario. Based on describing a typical control loop, in this paper, analysis of time structure is elaborated in detailed. According to the analysis of time structure, the delay of networked control system involves in the various aspects in the hybrid network, it is discussed in this paper. The measures are proposed to improve the situation of time delay.
