碩士 === 朝陽科技大學 === 資訊工程系碩士班 === 96 === An embedded system based automatic guided vehicle was developed and studied. This system is construed with an embedded system, microcontroller module, motor driving module, optical monitor module, anti-collision detecting module, battery voltage monitor module, and power regulator system. The embedded system coordinates the whole system. It reads the pre-programmed route data and then calculates and sends to microcontroller via RS-232. The microcontroller receives the command and send to correspondence I/O port. The motor driving module drives this system to motion. The motion status is detected by an optical detector module and sends back to microcontroller and embedded system. Three ultrasonic sensors were used to detect the environment change while motion. Those modules detect any barrier in front of this system while motion and send back to embedded system foe judgment. Power level detector can detect the battery status and alarm if it is at low voltage level. A high efficiency switching power regulator was used to convert battery voltage to 5 volts for control circuitry. This system can move according to the pre-programmed route. The pre-programmed data can upload via web browser. The anti-collision function was successfully verified when a barrier in front of the system.
