Abstract: In order to meet the requirements of tunnel drilling rig, a drilling parameter monitoring system was designed. The hardware sys-tem with the PLC as the control core, applying CoDeSys for designing software system ,and the signal collection and processing method was introduced in detail .the monitoring system adopt the CAN bus network and the upper machine as communication, the interface uses LabVIEW software was designed based on windows system of PC. Practical application results shows that the mon-itoring system can accurately display drilling parameters to the PC interface and save it., such as strong real-time performance, and high reliability.
