The resources shortage, resource exhaustion and environment pollution resulted from economic development awake people to think over how to achieve the sustainable development. Under the background, more and more governments, semiofficial organization, industrial association, and folk organization are beginning to pay more attention to environment and resources. Based on the cycle utilization of materials, circular economy could improve the utilization efficiency of resources and energy, and farthest decrease waste emission, and protect the ecology environment. The paper analyzed the circular economy in terms of the basic concept, the development mode, and circular system, which would provide some making-decision references for clearing the development thought of circular economy.

The ControlNet network is designed to be the central communication architecture for interoperating automation products. It provides fast, deterministic scheduled data transfer for control purposes and unscheduled non–time–critical messaging for configuration and house–keeping on the same network. This is accomplished by partitioning the bandwidth into a scheduled portion that is guaranteed to be delivered within a specified Network Update Time and an unscheduled portion that is essentially the time remaining after the scheduled traffic is handled. A critical user-supplied parameter for ControlNet is the Network Update Time or NUT. In this article, we studied the critical parameter of the ControlNet network when used in a control situation. Simulation results and conclusions are presented.
