The token ring-based industrial wireless monitoring and control network is constrained by the communicating distance of the wireless module.In order to extend the communicating limit and expand the application range,a two layer network based on the token ring with a master/slave network layer subordinated called Wireless Monitoring and Control Network Protocol-Two layers(WICN-TL) is proposed.The topological structure,and communicating procedure is introduced in the paper.The protocol is implemented on the NanoNET hardware platform based on the IEEE802.15.4a standard,accessed to the PROFIBUS-DP fieldbus system and tested in a sewage plant.The result shows that the protocol performs well in communication and the covered range is extend to apply to the industrial environment application demand.
