Abstract


\On the basis of this study , the successful development of the group control system based on PC motion controller \The control system NextMove ES controller as the core , the design group control system architecture . RS485, RS232 and CAN bus to establish a channel of communication between the group control system controller . Communication between each FEP and lower controller via the serial communication mode , based on the set communication protocol , and thereby control the movement of the respective stepping motors . For the group control system is easy to operate , safe and reliable , the software part of a mixed programming technology , the underlying software controller NextMove ES Language - MintMT the multitasking MintMT programming , to the upper-layer software section provides a communication interface , the upper layer software developed by VC system application interface module and various control functions . Timeout retransmission mechanism to guarantee the reliability of the control signal communication , and real-time dynamic calculation of overtime waiting time , thereby increasing the efficiency of the system . The modular design of the system software features to improve the scalability and versatility of the system . The group control system the actual SG - III prototype device laser alignment straight and diagnosis system to get a good application , system design development of the concept of \
