Wireless Control for Pointolite in Light-Pen CMMs

Article Preview

Abstract:

A wireless control system for pointolite on the light pen based on TMS320DM642 and CC2530 is introduced in this paper, in order to solve the problem that only pointolite's switch values could be controlled on the light pen in light-pen CMMs, but not lightening time values and brightness values. Through wireless networks of Zigbee, not only pointolite could be switched on or off separately, but also lightening time values and brightness values could be changed by TMS320DM642. Protocols of wired and wireless communication, multipoint answer and error reporting are also given, to improve anti-jamming capability of the system. The experimental result demonstrates that the control success rate could reach 96%, as the wireless modules of TMS320DM642 and the light pen within 8m. So the developed system has high anti-interference capability and could meet expected requirements.
