碩士 === 國立虎尾科技大學 === 電機工程研究所 === 97 === Based on CompactRIO programmable automation controller (PAC) technique, this dissertation implements the omni directional mobile vehicle hand-held control system, in which includes an ZigBee wireless transmission triple-axis accelerometer. By using LabVIEW graphical programming language and LabVIEW FPGA Module, the pulse width modulation (PWM) signals are designed to control motors speed and directions. On the other hand, the mobile vehicle motion modes are created by LabVIEW Real-Time module. Thus, in this dissertation contribute five main researches: (1) Manufactures the body structure of omni directional mobile vehicle. (2) Combines triple-axis accelerometer module with ZigBee wireless transmission module to create the hand-held wireless accelerometer controller. (3) Uses wireless broadband router to communicate CompactRIO and personal computer, and provides a wireless local area network control environment for omni direction mobile vehicle. (4) By using LabVEIW program design of graphical software, designs triple-axis accelerometer module, ultrasonic signal acquisition module, avoid obstacle function module, PWM signal control module, omni direction mobile vehicle motion algorithm, RS-232 transmission setup module, waveform width calculation module, and accelerometer control module. (5) Integrates omni direction mobile vehicle three control mode: Mode-1, PC human-machine interface control mode; Mode-2, wireless accelerometer control mode; and Mode-3, random motion mode.
