Research And Design Of PC Software System Based On PMAC Control Card

CNC System as compared with conventional NC system is a system powerful, convenient, expansibilitive. In recent years,the motion control card has been rapid developed, the CNC system is used more and more widely, especially in the universities and research institutes.The function of PC software, the first to It can communicate with the motion control card and guarantee the establishment of reliable communication connection.It can complete the data reading and real-time transmission, such as the current position and motion feedback each control shaft speed, or send to the lower computer control commands for motion control. It can monitor other equipmentby the expansion boards under computer control system.This software system can be widely used in other display and control software about motion control interface, can be used as an example the development of other related motion control PC card control system.The development of the software has certain universality.When G code open is open, Static simulation can generate formation of the static graph,and dynamic simulation in the machine tool movement to the different colors of the line between the trajectory of the current execution, it is convenient for the operator to observeIf this software has not developed, the other software of PMAC can also realize these functions.But the convenience is greatly reduced, on the one hand control the software with motion control system debugging functions, and these functions are not needed by user, on the other hand controling and display are confined, such as control command to users according to the control command to view the corresponding motion control card operation manual, then put the command line into the dialog box, and such as parameter display most also need to knock on the command line.Through the development of the project of OPC communication technology, we can solve the optimization control algorithm where is no place to write. Because modifying the PLC online program is not safe, and compiling in configuration software only by the script language, programming environment is not suitable for a large amount of computation and storage.With the programming language platform standard, procedure, portability read ability good, and in order to protect intellectual property rights, programming by Visual Basic can also be encrypted, with great technical advantages. Compared to VS2008 programming platform through the drop-down menu to select and click on the button and the indicator light shows much more complex.
