Development of Remote Control Device in Numerical Control System

Numerical Control (NC) system plays a vital role in industrial automation. For large cutting machines, centering is a frequently used and important operation. Due to the long distance between the console and the burning torch, it's hard for only one operator to accomplish this work. In this design, remote control is added to the traditional NC system, which is a good solution to the problem. As to hardware design, STC10L08XE is chosen as the main chip and CC1100 as the RF (Radio Frequency) wireless transceiver chip. As to software design, the reliable wireless communication between two modules is realized with CRC check and the mechanism of automatic retransmission, so as to ensure reliability in disturbance. This design realizes the control of machines with remote control, so that operators can move freely and not limited to console. This not only saves labor but also improve the production efficiency, thus having a good application prospect.
