Research on Wireless Communication Technology of WS-mCNC System

Two wireless communication technology standard are analyzed including the common bluetooth technology and IEEE802.1, they were compared firstly at same time in this paper. Further we analyse bluetooth protocol system structure and bluetooth protocol stack, protocol stack is the core part of bluetooth technology realization, it ensures the connection between the device and data exchange and security. Bluetooth protocol stack adopts event-driven multithreading operation mode, the bluetooth configuration, application model configuration corresponding agreements, procedures and their combination order, so these meet the demand of equipment. Meanwhile MC and DC bluetooth communication realization process of WS-CNC are studied, the design application includes two parts, one runs in DC side, the other part of the running in MC, design the communication protocol, through experiment, obtains the DC and MC bluetooth communication results, so that realizes the important part of the flexible manufacturing unit (the workshop HMC), thus fulfilling the workshop agility, rapid organization, to better support the man-machine coordinated, effective coping workshop dynamic production environment.
