The design of control software

Teaching type CNC engraving machine, CNC engraving system control software adopts the modular design method, by teaching control, signal acquisition, data processing, coordinate motion control, communication monitoring, interrupt handling module, as shown in figure 3. The content of the software system of master control program include: system initialization Settings, such as key analysis and display of three parts. Initialization setting main effect is to make the whole control system in a state of work ready. Key including digital key and function keys analysis two parts, each function key has the function of the corresponding service program. After the analysis of the function keys, execution and its corresponding service program, and automatically return to the master program. Teaching control module is used to control the operation of the teaching organization, using the international teaching instruction information control teaching institutions along the target direction. In teaching process, the tool path information to complete a collection by the signal acquisition module, as defined by the set of acquisition system control method and the patch, automatically record the relevant information. Data processing module is used to deal with to collect the information and data automatic CNC engraving processing needed for the control program. According to target coordinate control module is used to control the carving machine control program is running, carved processing work to complete. Communication monitoring module used to implement the control system of the communication with other computer systems, in order to use other computer hardware software resources expansion system control functions, to form a multifunctional distributed control system. Interrupt handling module used to handle the problem of system operation process ( Such as tool breakage after the replacement, etc. ) , interrupt system normal operation, and to protect the original state information, after the interruption, automatically return to normal working state, continue to run.
