Abstract: To solve problems of large dimensions, high cost and non-uniform programming interface existed in mine-used display, the paper introduced design of a mine-used LCD display platform based on embedded system. The hardware system of the platform adopts ARM9 and integrates many functions of display, communication and A/D sampling ; software system uses operation system of embedded Windows CE as platform and adopts embedded LabVIEW as user interaction software to edit display interface, and has advantages of convenient extend, efficient and beautiful interface. The platform can also match with electrical control devices through some communication methods to display state, alarm message of tunneling machine. The practical application showed that the platform has faster communication and display speed and good display effect.
