Abstract
A new method that Bluetooth wireless communication network applied in all-software NC system is proposed to diagnose the fault in NC system. NC system is connected with PDA by virtual serial port technology. Virtual serial port in PC is directly accessed with NT port software. The information of NC machine, including NC code, cutter location data and so on, is regularly accessed from top-level application program by wireless communication module with timer component in C++Builder6. Bluetooth wireless communication system is embedded in all-software NC system based on windows OS by above-mentioned method. Sending data module program in Bluetooth wireless communication system is designed in C++Builder6. Receiving data module program is compiled by evb3.0 in PDA. The information of NC machine is saved as the Access file in PDA database by ActiveSync software. In the experiment based on the method above, PC is connected with PDA by virtual serial port. Process information is successfully transferred to PDA While NC system is running.
