Abstract: For improving the performance and competitive power of the weaving machine′s control system of our country,in this paper,the movements of electronic dobby rapier weaving machine were analyzed.Based on multi-layer finite state machine concept,which manages control tasks in a structural,hierarchy way,the software control system of electronic dobby rapier weaving machine was designed.The state transition relations of electronic dobby rapier weaving machine were clearly defined.And the corresponding design processes were given in detail.Phillips′s LPC2214 was chosen as the main chip,which is based on ARM microcontroller,to design the hardware platform for implementing the complex process control of electronic dobby rapier weaving machine,while μC/OS-Ⅱ real-time operation system was used to design the software.
