Design and Application of Multi-Terminal Parameters-Monitored System Based on ARM for Tunnel Drilling Rigs

In order to know the working state of drilling rig in far distance without going near the working site, a new control method of multiterminal parameters-monitored system based on ARM (Advanced RISC Machines) for coal mine tunnel underground was introduced in this paper. Firstly, the input signal from sensor module was transported into ARM processor and treated, and then outputted to all the display terminals in multi-optical signal through the communication processor circuit, at last the parameters will be displayed on screen after a conversion process of optical signal. In this paper, a brief introduction of tunnel drilling rig was firstly done, and then the control scheme and principle were introduced, the hardware and software were designed in detailed, at last it was proved in actual project application that it has the merits of easy installation, far monitoring distance, multiple terminals and flexible display with high project application value.
